Abstract
Indonesia has the highest potential of geothermal energy in the world with 30 GW. However, the utilization ratio is low with around 5% only. This situation occur since there are several geothermal energy targets failed to be achieved. The development of geothermal energy have several problems and one of them is rejection in the community when geothermal development begins. To overcome this situation, an increase in community understanding of this technology usage needs to be conducted. Therefore, the objective of this study is to discover public understanding by exploring the knowledge of vocational high school students about geothermal energy. This is conducted because they are young people who are part of the community. Their knowledge plays an important role in selecting energy sources for the country in the future. This study uses a triangulation strategy model that combines quantitative and qualitative methods. Respondents were students in Indonesia with a case study in Karanganyar Regency, Central of Java. Knowledge is measured by an indicator of the level of understanding of geothermal technology.

Abstract
Cathfish cultivation in Indonesia is a very promising business opportunity with a big profits. Every year, market demand continues to increase. However, this is contrary with the lack of catfish farmers knowledge, so that catfish yields are not optimal. This is because, for certain types of catfish such as Sangkuriang catfish, it is easy to contract certain diseases. This study aims to create an automated system that capable of detecting catfish disease based on its symptoms with image recognition techniques. Early detection of catfish disease can help to find out the causes and prevention, so that the yield remains optimally. The method that used in this study is Principal Component Analysis (PCA) for feature extraction in images combined with K-Nearest Neigbor (KNN) with Euclidean Distance to classify catfish diseases among others: white spots, edema (abdominal swelling), jaundice, and bent spinal disease (scoliosis and lordosis). Based on the results of the experiment using 30 images data for training and 20 images data for testing, 18 image data is classified correctly. This result proves that PCA and KNN able to detect catfish disease well with percentage of accuracy around 90%.

Abstract
By using the one-dimensional canonical partition function, we modeled an ideal gas-like form of a set of Bose-Einstein condensates confined by a three-dimensional anisotropic parabolic trap. The model itself was constructed by taking the eigenenergies of the one-dimensional Gross-Pitaevskii equation in the longitudinal direction and enabling the harmonic volume as the inverse cube of average geometric trapping frequency to substitute the available volume. In this paper, we showed that the condensates form an ideal gas represented by its equation of state and have similar mature to Einstein solid-like model with corrections both in the low and high temperatures in the internal energy formulations.

Abstract
The development of the world internet usage continues to increase from time to time. It is recorded that 46% of the worlds population has become internet users and generates data traffic of 8 zettabytes every day. This increase has triggered the growth of data center infrastructure as processing, storage and communication system in the digital world. The data center itself has contributed 1.5% of total world electricity consumption and is expected to continue to increase. With the proportion of energy use in the data center, it covers 52% of electrical energy for information technology (IT) equipment, 38% for cooling and 10% for supporting equipment. One of the problems faced by data centers is the cooling of information technology (IT) components that are relatively large in energy, this has been a separate concern in several years of research. This paper describes cooling models that have the potential to improve the efficiency of using energy data centers. There have been many studies using several methods in order to find the most effective way to transfer heat data centers, one of them using the immersion cooling method. Immersion cooling promises energy efficiency improvements in the data center, using dielectric fluids that have high heat capacity. Several types of fluids and immersion cooling methods are identified and discussed in this paper.

Abstract
Multivariate Control Charts is an effective tool in Statistical Process Control to identify either an out-of-control process or in-control process. Hotelling T2 control chart is a quite popular and widely used technique in this field. However, its performance is deteriorated when the underlying distribution of the quality characteristics is not following the multivariate normal distribution. Multivariate control chart usually recommended a procedure in the phase-in Hotelling T2 control chart although there is difficulty in interpreting the signals from multivariate control charts more work is needed on data reduction methods and graphics techniques. Basically, the multivariate control chart refers to the theory of prediction interval. Therefore, its called predictive multivariate control charts. We aim to construct what so-called predictive multivariate control chart both classical in this part in the phase-in Hotelling T2 and Copula-based ones. We argue that appropriate joint distribution function may be well estimated by employing Copula. A numerical analysis is carried out to illustrate that an Application Copula-based Multivariate control chart outperforms than bivariate control chart and others.

Abstract
The ability of students to determine their chosen field of expertise is still subjective, many students choose the field of expertise because their classmates choose the field of expertise not by considering their abilities and interests. This research uses the KNN classification method to determine areas of expertise that are in accordance with student expertise. The KNN method was chosen because it is a method that uses supervised algorithms where the results of new query instances are classified based on the majority of the categories in the KNN whose purpose is to classify test data based on training data. This system was tested using the confusion matrix method and the results were 98.30% of the total student data sample of 30 people.

Abstract
Every factory based on production, always try to find the best way to get high profit from their capital that spent on production processes. The Konveksi Zom T-Shirt is a factory that produces jacket, shirt and t-shirt. This factory, use simplex method to predict composition and number of items to get maximum profits from available capital. Based on simplex method with parameters; Rp. 2.000.000 as capital, 3.000 minutes as time production, and 6 pcs as minimum productions. This method get result with composition and number of items; 15 pcs of jacket, 6 pcs of shirts, and 22 pcs of t-shirts. The profit of production uses this method can increase 3,5% of profits from conventional method. Finally, this method can be used to support on deciding composition and number of item in productions to get a maximum profit.

Abstract
Children who are physically hurting others intentionally is a behavior that showed a lack of ability to manage conflict, less control in managing emotions, or lack of ability to convey the desired appropriately. Teaching children to resolve conflicts is a strategy that can be used to create more adaptive behaviors. Children are taught how to resolve conflicts with some of the approaches that suit the environment will grow into adults who are better to cope with emotional problems, especially with other people in the neighborhood. The problem-solving strategy in this research used technological approaches, MATA which is the development of Android-based media where children with aggressive behavior problems can be used MATA as a tool to express emotions through art. Children can freely express their thoughts and feelings visually through color scratches; they can also see the results of their work in three dimensions. The method used in this research is the experimental method. Determination of the research subjects with a purposive sample previously granted WPS Aggression Questionnaire and choose a subject with aggression medium-high categories, the number of subjects in this study were five children each in the control and experimental groups. Results showed that the experimental group experienced a decrease in the level of aggressive behavior than the control group.

Abstract
A monitoring technology for large area with low-cost and high efficiency is highly demanded. Wireless Sensor Network (WSN) is the solution for a monitoring technology. However, not all monitoring must be continuous, there are some monitoring that can be carried out periodically. Therefore it is possible to invent a mobile sensor communication system on multicell networks. This research aims to implement a WSN system by collecting data from mobile sensors on multicell networks. The focus of research is on the design of mobile sensor communication with low-cost device as transceivers, namely NodeMCU. The design is implemented using 4 NodeMCU units, 3 of them are functioned as access points, while 1 unit is employed as a client connected to the sensor. The experimentation was conducted by varying transmission distances of sensors with and without barriers. Moreover, handover and blankspot areas are also included accordingly. The result of experimentation shows that the usage of low-cost devices has still possibility to built monitoring mechanism on multicell networks eventhough the transmission power was significantly influenced by the availability of barriers.

Abstract
Encyclopedia anatomy is an android application to introduce anatomy, equipped with a search feature, multiple choice quizzes and guess image quizzes. Due to some anatomical term is uptake from foreign languages and frequently typing errors by smart phone user, then search feature in this application implement fuzzy string matching method which use levenshtein distance algorithm. However, the results obtained are still not accurate, then added method of splitting and indexing so the results are more accurate and search process fast enough. Due to more simple than book and supported by a good appearance, this application is able to get a positive response from the users.
