The index of tourism suitability and the carrying capacity of the tourism region is a matter of concern on the management of marine tourism area and need to be developed to reduce the impact of environmental degradation. Therefore the tourist area can be maintained its sustainability. The purpose of this study is to determine the level of tourism suitability and the carrying capacity of marine tourism areas, especially on snokeling activity spots in three islands of the Thousand Islands National Park, namely Pulau Ratu, Pulau Macan, Pulau Genteng Kayu Angin. The method used is suitability marine tourism area index formula and descriptive method. The result showed the snorkeling tourist suitability tourism index of the three islands on 12 stations showed 5 stations had suitable criteria (S1) and 7 stations conditional suitable criteria (S2). This means that the three islands were still appropriate to be used as a tourist snorkeling area. But if these 12 snorkeling station in the three islands are not managed then there will be damage to the coral reefs. The carrying capacity analysis showed that the value varied according to the spacious area to the tourism area measure that has the suitable criteria (S1) which ranges from 80 to 130 person per day. However based on the number of tourists that exist in 2017, the carrying capacity had exceeded the maximum limit, which is above 150 people / day, meaning it had passed the ability of tourist area to support the number of tourists.

The food self-sufficiency performance in West Java Province faces a very complex challenge in line with the decline in agricultural land area and population growth. This study aims to evaluate the performance of food self-sufficiency in West Java Province during the period of 2007 - 2015 using the indicator of the ratio of food self-sufficiency. The focus of this research is directed to rice commodities. The analysis in this study used a descriptive analysis of food self-sufficiency performance and the factors that influence it. The analysis shows that although the area of agricultural land was declining, rice production tends to increase. This was driven by rising rice cropping index and increasing productivity. On the other hand, rapid population growth in West Java Province encourages increased consumption of rice. The growth rate of rice consumption was greater than the amount of rice production, especially since the period 2011 - 2015 leads to a decrease in food self-sufficiency in West Java Province which was illustrated by the trend of decreasing the ratio of food self-sufficiency.

Image processing plays a very important role in medical imaging. As medical imaging is used most widely in areas such as Magnetic Resonance Imaging, Ultrasound Imaging, X-ray Scanning, etc. It is necessary to obtain the clear view of the images for proper diagnosis of the patient. Ultrasound Imaging is used to detect the status of the fetus in the womb. By measuring certain parameters such as Bi-parietal Diameter (BPD), Head Circumference (HC), Abdominal Circumference (AC) and Femur Length (FL) the weight of the fetus is being calculated using Hadlock IV formula. This detection would be helpful for the detection of the abnormalities of the fetus during the earlier stages of pregnancy automatically.

Textile industry consumes the most amounts of dye lots in the production process which have a non-biodegradable in nature. It is necessary to do the dye wastewater treatment before discharging to the environment. Photodegradation is a process of decomposition of organic compounds with the aid of photon energy, in which oxidation and reduction reactions occur on the surface of the semiconductor. One of the good semiconductors used is ZnO. Furthermore, adding a matrix or dopants is expected to assist ZnO photocatalysts so that dye degradation is more optimal. Zeolite is a good solid support for dispersing ZnO semiconductors because zeolite has large surface area and uniformity of pore size. Procion Red was used as a model of synthetic dye wastewater. The objectives of the study are to synthesize ZnO-zeolite composites by impregnation method and to study the effects of irradiation time (30-120 minutes), type of composites used, and light conditions (dark room, UV light, and sunlight) on Procion Red degradation. ZnO-zeolite composites are made by weight ratio (1:2), (1:1) and (2:1). ZnO-zeolite composites that have been synthesized were characterized by using SEM-EDX. The degradation of procion red dye produced was characterized by using UV-Vis Spectrophotometer. The results showed that Procion Red degradation by using sunlight exposure was greater than UV lamp and dark room for Procion Red concentration of 150 mg/L. From the three ZnO-zeolite composites synthesized, the composite (2:1) showed the best degradation percentage of 83.96% for 120 minutes under sunlight irradiation.

With the affluence of information produced by users in websites, people have problems to find the best information. Recommender systems are a big ingredients of online systems such as e-stores e-commerce providers. Recommendation methods use information available from users-items interactions and their contextual data to provide a best list of items for users. These methods are constructed based on similarity between users and/or items (e.g., a user is likely to purchase the same items as his/her most similar users). In this paper, we introduce a novel community detection recommendation algorithm that is based on rules. Community detection create groups of interacting vertices (i.e., nodes) in a network depending on their structural properties .We can extract rules in users-items interaction network .use this rules can help recommendation process. We apply the proposed algorithm on a movelense dataset. Our proposed method show better precision as compared to the state-of-the-art recommenders.

This paper introduces a novel approach to obtain full three-axis movement in a frictionless spacecraft simulator. This simulation system is intended to test attitude determination and control stabilization subsystems for 3U Cubesats, however, it is not constrained to this group of Nanosatellites, scalability to 1U or 2U is readily available. The spacecraft simulator consists of a cup, supplied with air pressure, and a hollow sphere floating in the air cushion generated between these two components. This air cushion provides an almost frictionless environment. The Cubesat is attached inside the sphere, allowing it to have a non-restricted movement of 360 arc degrees, in the three-orthonormal axis around its center of mass. The sphere is in fact made of two pieces to allow access to the spacecraft. In this scheme the spacecraft simulator it is not instrumented with attitude and rate sensors to send its orientation by telemetry to the Earth station, as usual. In this case the own attitude instrumentation of the nanosatellite under test is employed to comply with this task. Design and functioning tests of this approach for attitude determination and control system assessment for nanosats are introduced, and for demonstrative purposes LQR and PID attitude control algorithm were implemented on board a 3U Cubesat, in order to test the entire simulator.

the field of parallel processing is concerned with architectural and algorithmic methods for enhancing the performance or other attributes (e.g., cost-effectiveness, reliability) of digital computers through various forms of concurrency. In our paper, distributed memory systems depend on client/servers principles. The algorithms used here are capable of calculating the started, consumed, and terminated CPU times, total execution time and CPU usage of servers, and CPU and total execution times for the client. This work addresses an improved approach for problem subdivision and designs flexible algorithms to communicate efficiently between client-side and server-side so as to overcome the problems of hardware networking components and message passing problems. There are three main trends in this work; the Distributed Parallel Processing technique depending on MPI Messages, Effects of Multi-core Systems on MPI Messages, and Shared Memory System Parallel Processing. Each trend is presented via a case study. All these algorithms are designed and tested completely in this work. The algorithms are implemented using Java language and C# Language.

The purpose a significant amount of operation issues do exist in local supermarkets and their supply chains confirming the need for their operational agility. The agility of supermarket chain mostly was associated to the capability of operation that responds to the increasing pressure of variability in customer demand and changing customer buying behavior. The paper therefore examines the agility of supermarkets supply chains to manage the inventory issues in meeting the customer order fulfillment. Cross-sectional study included survey data from managers of supermarkets which is spread over the big cities in East Indonesia. This also included the manufacturers and small retailers as partners of the supermarkets chain. A total of 164 usable responses, representing 40 per cent responses rate, comprise of 60 supermarkets and 104 manufacturers and retailer together. SEM modeling was used to find out the hypothesized relationship among the variables in a conceptual framework. Results of the study show that information and communication technology (ICT) plays an important role in managing supermarket inventory through its supply chains agility (SCA). The results also show that the supermarkets suffer from quick response to their consumer need, inventory stock out, higher distribution lead-time and lack of order fulfillment. The finding can offer an insight to the operation managers about the ICT usage that can provide an agility to overcome their inventory issues there by maximizing service level. The supermarkets need to be quick in response to meeting their customers’ requirement. Unfortunately, some supermarkets have too many issues in serving the customers. Limited use of ICT with the suppliers and retail customers results in inventory shortages, higher distribution lead time and low service level. The paper aims to fill this gap by investigating how managerial practices may increase the agility in the supply chains especially in managing the inventory using ICT as enabler.

Diabetes mellitus is a group of metabolic diseases showing high blood sugar levels over prolonged periods. It is one of the deadly diseases growing at rapid rates in developing countries. Diabetes has affected over 246 million people worldwide. According to the World Health Organization (WHO) report, this number is expected to rise to over 380 million by 2025. If untreated, diabetes can lead to long-term complications such as heart disease and kidney failure. Therefore, there is a great need for the timely diagnosis of diabetes for people around the world. In particular, diabetes has been identified to be a very serious threat to younger generations and working individuals. Diabetes can be managed if it can be predicted during the early stages with changes in the diet and lifestyle of the patient. Therefore, this paper proposes a model for the early prediction of diabetes by considering major risk factors. An artificial neural network model with the Levenberg-Marquardt training algorithm is built using the PIMA Indian Diabetes dataset. The objective of the study is to predict the occurrence of diabetes mellitus using known risk factors based on feed-forward artificial neural network.

Shortest path algorithms are among the most studied network flow optimization problems introduced to in such approach such as ants colony, Greedy, Floyd, K and k* algorithms. In this paper we introduce a new algorithm to find the shortest path between two centers (nods), these nods may be represent a fire zone, bus station, cities…etc.In this algorithm nods will be represents as a matrix, the number of columns and Rows equal to the number of arcs of the network. The elements represent as 0 that means that there’s no arc between the centers (nods), or 1 that’s mean there’s an arc between the two centers. The solving of this matrix occurs in many stages: Stage1: specifying the number of arcs in the network by calculating the number of elements equal to 1 as arrow of matrix. Stage2: specify the number of arcs by identifying the number of rows and columns hold the value 1. Stage3: count the length of the paths depending on the arcs which is installation the paths and compare between these paths to specify the shortest path. So in this algorithm we need just to inter the number of arcs, start state node and goal state node of the network, we choose VC++ as a language to program this application in, a compiled program will always be faster than an interpreted program.

Effects of tillage depth and forward speed on draught power of primary tillage implements were studied using a pull dynamometer in silt loam soil. The implements used were a standard 2-bottom mouldboard plough and a 3-bottom disc plough. Tillage depths of 6.5 cm, 12.5 cm and 22.5 cm and speeds of 1.3 m/s, 2.3 m/s and 3.0 m/s were used. The effects of the treatments were studied using randomized blocks. There was significant increase in draught power with increase in tillage depth and forward speed at all the levels of the treatments tested for both the ploughs used. It was also noted that the draught power for mouldboard plough was higher than that in the disc plough at all levels of the parameters tested. Power requirement for mouldboard plough changed from 4.416 kW to 7.029 kW when tillage depth was varied from 6.5 cm to 22.5 cm. This results into an increase of 0.163 kW per unit change in depth of tillage. For the case of disc plough it increased from 3.344 kW to 6.404 kW which is equivalent to an increase of 0.191 kW. When speed was increased from 1.3 km/hr. to 3 km/hr. for disc plough power requirement increased from 2.911 kW to 7.048 kW resulting into an average change of 2.434 kW for the corresponding change in speed. While for the mouldboard plough the change was 3.12 kW within the same range.

Cybercrime or cybercrime on computer programs or programs is considered a serious crime at the present time. State legislatures have provided legal protection for the legitimate use of the computer and the information network and the punishment of perpetrators of acts that constitute an attack on the rights of their users Or to prevent misuse of computer crimes. However, Arab countries, especially Iraq, are still far from legislating an e-crime law, despite the proposal by the Iraqi government in early 2011 to undermine the use of information technology and social networking sites through a project called the Cyber Crime Act. Cyber-crimes the off-spring of the cyber-space technology could be just observed; controlled and counteracted through digital enactment. Nations around the world are confronting the threats of digital violations because of a few reasons extending from the poor innovation, inadequacy and nonappearance of enactment to money related requirements, resistance with universal law and authorizing organizations. This examination was attempted to asses and breaks down the current situation with digital violations and enactment in the point of view of creating nations and to distinguish and investigate the difficulties the legislatures of creating nations are looking in the anticipation of the digital wrongdoings .

The leadership styles of supervisors can have a significant influence on motivation levels of subordinates [1]. Yet, there is a lack of empirical examinations to validate such effects of contemporary leadership styles on employee motivation in public sector organizations in South-Asian context. To plug this gap in literature this paper aimed to examine the implications of supervisor leadership styles on subordinate motivation in a public sector organization in a South-Asian culture. Thus, pledged the research question ‘What is the impact of leadership style on staff motivation in a public sector organization in Sri Lanka?’ This study used a mixed method research design where interviews and questionnaire were used for data collection. Participants were from a department of a government institution in Sri Lanka. The total sample size was 32 for the questionnaire and 4 for the interviews, where the population size was 46. Response rates for the questionnaire and the interviews were, 93.75% and 100%, respectively. It was found that the leadership style at the research site to be more transformational than transactional. Furthermore, transformational leadership demonstrated a positive effect on subordinate intrinsic motivation, while it affected negatively for subordinate extrinsic motivation. In contrast, transactional leadership indicated a negative effect on subordinate intrinsic motivation, while a positive effect was indicated on extrinsic motivation. The study concluded that transformational and transactional leadership styles have a significant effect on employee motivation, while laissez-faire leadership style is ineffective. Since the findings were consistent with the leadership literature, contemporary leadership styles were viewed as valid and applicable for the public sector organizations in Sri Lankan context. The small sample size and longitudinal effects were identified as the limitations of this study.

This study aims to analyze how Law no. 19 of 2016 on Information and Electronic Transactions (UU ITE) regulates the position of new norms regarding the right to be forgotten in Indonesia. Indonesia became the first Asian country to apply the concept. The right to be forgotten is a norm in the field of cyber law. It was born out of a desire to restore the control function of personal information circulating on the internet to the personalities of each person. Although this concept is adopted from EU countries, it is not the same application in Indonesia. Deletion of content in the EU or Russia or other countries that apply only limited to the search engine (search engine), in Indonesia is not like that. It is expressly referred to in Article 26 paragraph (3) of the revision of the ITE Law: "Every Operator of Electronic System shall remove Electronic Information and / or irrelevant Electronic Documents under its control at the request of the Person concerned pursuant to the court's determination". The results obtained 1). In Indonesia one can request a direct removal of irrelevant content, while in many countries the implementation of the right to be forgotten is limited to search engines, 2) content that can be applied for removal not only of content relating to personal data, but more broadly . 3) to irrelevant information or electronic documents, one may request removal pending judicial appointment.

Beach resorts in the Philippines aimed to build and maintain high quality services available to the clienteles in order to compete in the global market especially this time that ASEAN Integration came in to the country’s business systems. Banana Beach Resort in particular, is considered as the leading elite class resort in Mindanao that is committed to render services beyond compare and beyond its best for the benefit of all clients whom we labeled as beach resort goers. A descriptive-correlational design of research was used and it employed quota sampling in administering the questionnaire to the respondents. Data were statistically treated and analyzed. Presentation and Analysis were done in accordance with the research questions. Findings, revealed that all of Banana Beach Resort services; Accommodation, Food and Beverage, Water sports and Tours were much extensive. In like manner, the researcher had found out that the clients of Banana Beach Resort were much satisfied from the services they have received. Surprisingly, data revealed that the relationship between the services of the resort and the level of satisfaction is found “Not Significant”. It implies that the services of the beach resort have no significant relationship to the satisfaction received by the clients. This is well supported by Professor Noriaki Kano in his Kano Model Theory that states that customer satisfaction is not always proportional to how fully functional the product or service is or in other words, higher quality does not necessarily lead to higher satisfaction for all product attributes or services requirements. It was then recommended that Philippines’ beach resort owners specifically the banana beach resort must consider the Kano model theory where the focus lightens the 3 attributes to satisfaction: 1) basic or expected attributes, (2) performance or spoken attributes, and (3) surprise and delight attributes in order to develop a more comprehensive services that will give a full satisfaction to the target market.

The Software-defined networking (SDN) is an approach to computer networking that provides an opportunity for the network administrator to initialize, control, change, and manages networks programmatically via open interfaces and abstraction of lower level functionality. The old network architecture (NA) has been using the traditional networks, thus inefficient due to internetworking devices inability to support scalable computer requirements is digitalized and real time. The newest of NA is designed as a platform efficient to resolve the issue of traditional networks by decoupling and disassociating of NA responsibility is to control and making decisions in order to traffic concerns. Some of the typical systems associated with SDN include OpenFlow protocol, Cisco Systems, Open Network Environment, and network virtualization platform. The changes in technology signifies the important for the new NA that acts as a response to select in traffic patterns. Besides, the new network architecture must respond by providing a traffic pattern for the managements and flexibility of users traffic. The network architectures need to take advantage of the new cloud services and create a network that suits the interests of the potential users. This study focuses on showing how SDN deployments can be used to improve the manageability of NA, and OpenFlow can be used to create end-to-end switches and allow users to attain their objectives using efficient network architectures. The study utilizes the use of multi-case research method in analyzing the measures to be implemented for improving the efficiency of SDN. Also, investigates the different management networks traffics and their role in bolstering networking ability. The study is proposing the most harmonious method that network managers need to prioritize when it comes to deploying their network architectures. This is for ensuring so they select a NA that is easier to manage and affordable. SDN is an important tool used in improving networks and efficiency of a network. This paper, therefore, uses SDN in convincing network managers and other concerned partners about the importance of ensuring that their network is deployed on SDN. The paper further uses OpenFlow model as the primary simulation method.

By the advancement of technology, most healthcare queue management systems assign a turn number to the patients online. In traditional healthcare queue management systems, all patients are considered to be in the same priority, and only the amount of doctors and patients' wasted time is optimized. While the lives of humans are more important than time. Therefore, in the proposed method in this study, the most important issue that is considered is to give priority to patients who are already in worse conditions. At the same time, it has been tried to minimize the waiting time for doctors and patients. The proposed system prioritizes patients to receive their services according to their health and vital status, and then optimizes the visit scheduling of patients using the genetic algorithm. The results implemented in Visual Studio and SQL Server software show the effectiveness of the proposed mechanism in scheduling and prioritizing.

Strawberry pulp and sugar level was maintained at 6% and 8%, respectively. Physicochemical, physical, textural and microbiological quality of developed yogurt was investigated during storage at 4±1°C against control yogurt made by milk standardized with skim milk powder. Significant (p<0.05) increase of acidity development and pH reduction was observed with advancing storage period, irrespective of the type of yogurt. Whey syneresis appeared only in control yogurt on 13th day of storage. Water holding capacity was significantly (p<0.05) higher in developed compared to control yogurt. Acetaldehyde concentration significantly (p<0.05) decreased with advancing storage period and was significantly (p<0.05) higher in developed yogurt throughout the storage. Values of textural attributes increased significantly (p<0.05) with increasing storage period irrespective of the type of yogurt and significantly (p<0.05) higher in developed yogurt. Lactic acid bacteria count decreased significantly (p<0.05) and yeast and moulds increased significantly (p<0.05) with advancing storage period in both yogurts. After 13th day of storage, overall acceptability of the developed yogurt decreased significantly (p<0.05) due to flavor and acidity related changes. Developed strawberry yogurt had 1.30 times more protein and 1.24 times less lactose compared to control. On the basis of increased yeast and mould count and sensory defects, shelf life of developed yogurt was observed to be 13 days at 4±1°C.
