Indonesia Power UPJP Kamojang https://stt-pln.e-journal.id/kilat/article/view/643 <p>Geothermal as a newest natural resource for Indonesian. PLTP PT. Indonesia Power as one of subsidiaries of PLN that is focused on generating using geothermal resource. One of the important components in the system of PLTP is a generator. PLTP Kamojang had been operating for about ±30 years, where there are still some problems that will reduce the efficiency of generator. The generator at PLTP Kamojang unit 2 must be operated more than 90% so that it will be able to supply electric power for 150kV. If the generator operated with the efficiency under 80%, so the supply of energy will not be maximum, because there are so much energy of electric lost caused by the losses in the generator. That is why needs to be analyzed toward the efficiency of the generator, whether the generator still works optimum or not. The result of analyses from the month of February 2019 as long as 1 month, found that the efficiency of generator unit 2 is about 92,888%. If comparing by the efficiency of generator as design as much as 98,4%. The efficiency value of the generator unit 2 Kamojang is decreased for about 5,51%. This condition showed that the generator still reliable one in supllying electric power.</p> Muharrir Muharrir Ibnu Hajar ##submission.copyrightStatement## 2019-10-06 2019-10-06 8 2 93 102 10.33322/kilat.v8i2.643 Penerapan Metode Triple Exponential Smoothing Pada Sistem Prediksi Keuntungan Bisnis Ayam Broiler Guna Meningkatkan Pengelolaan Keuangan Peternak https://stt-pln.e-journal.id/kilat/article/view/551 <p style="margin: 0px 0px 10.66px;"><em><span lang="EN-ID" style="margin: 0px;"><span style="font-family: Calibri;">Profitable business predictions are used to help chicken breeder in anticipating profit earned in the next harvest. The existence of a profitable prediction, enables breeder to predict when the next harvest is experiencing little profit or harvest failures. In addition, to be the breeder still has risky capital and bankruptcy. In this research, the author compare two methods accordingly in this case, there are triple exponential smoothing method and monte carlo method. The data used in the calculation of news data is profitable on the previous harvest. To find the value of two methods are match, the author's use mean absolute percentage error (MAPE) to learn the percentage of the value of the error. Based on the value of MAPE, triple exponential smoothing method have value of 12.10% with α value = 0.3 and monte carlo method have value of 40.58%. Meanwhile with the anticipated value of profit testing for the next 2 harvest grab the difference up to Rp. 19,935,410.</span></span></em></p> Dine Tiara Kusuma Muhammad Farid Rifai M Yoga Sudirman ##submission.copyrightStatement## 2019-10-06 2019-10-06 8 2 103 111 10.33322/kilat.v8i2.551 Implementasi Metode Regresi Linier Berganda Untuk Proyeksi Kebutuhan Listrik Dalam Rangka Analisis Strategi Bisnis Di PT XYZ https://stt-pln.e-journal.id/kilat/article/view/560 <p><em>E</em><em>lectrical energy requirements in the Industrial Estate should be fulfilled as a supporting industry in the region in order to develop.

So they experience emotional instability as a result of adjusting themselves to new patterns of behavior and social environment. Personality and behavior disorders in adolescents are problems faced by parents and their environment. In this study, this knowledge was obtained from experts, namely psychologists. This study uses an interview method with a Psychologist. The expert system is a system designed to assist in detecting diseases with a dynamic knowledge base. This expert system can deduce the user's illness based on the symptoms of adolescent personality disorders that are entered into the system. As for the purpose of the research is to produce an expert system to assist psychologists in documenting their knowledge. The expert system will display the amount of confidence the symptom has on the possibility of the user's illness. The amount of the trust value is the result of calculations using the Certainty Factor (CF) method. The results obtained from this study are the application of an expert system to diagnose adolescent personality disorders with the certainty factor method by using a computer as a tool to access data</em></p> <p><em>Teenagers, Adolescent Personality Disorders, Expert System, Certainty Factor</em></p> Adi Suwarno Ishak Husin Ulfi Elana Zenni ##submission.copyrightStatement## 2019-10-08 2019-10-08 8 2 127 140 10.33322/kilat.v8i2.602 Implementasi Jaringan Nirkabel BWA (Broadband Wireless Access) Menggunakan Wimax https://stt-pln.e-journal.id/kilat/article/view/408 <p><em>Broadband Wireless Access is new standard of Wireless LAN (WLAN) developed by IEEE which standard is 108.16.The significance of BWA is wide area coverage, more users and without Line of Sight in some situation.

A good perception will guarantee customer satisfaction. This study aims to determine the extent of the influence of brand image (X<sub>1</sub>), service quality (X<sub>2</sub>), both individually and jointly towards customer satisfaction (Y). The research was conducted at the Language Development Center (LDC), a work unit at STT-PLN which organizes the English Proficiency Test (EPrT) for final year students in all majors. The study was conducted for 6 months, from December 2018 to May 2019 where EPrT was held 5 times with 987 participants. Descriptive and inferential analysis was conducted to obtain administrative and questionnaire data. Samples were taken randomly using Slovin formula and produced 100 respondents. The questionnaire was processed by assumption test (validity, reliability, and normality) which then the data was processed by correlation analysis and path analysis to reveal the magnitude of the influence between variables both individually and collectively. The results showed that individually, brand image and service quality provided a positive trend toward customer satisfaction. Brand image has an effect of 25.5%, while service quality is 73.2%.

In this case the 200 WP solar module is used as an experiment to see the symptoms produced during a certain time. The material of the solar module is silicon oxide crystal (SiO2). The process of converting solar energy into electricity can be affected by the angle between the rays that come with the solar module field. If the position of the solar module does not change throughout the day, this angle depends on the position of the sun or time. In this case, it is necessary to study how the angle that produces the most electricity is adjusted to the change in time in one day. The energy produced by solar tracking systems is more optimal than that of solar modules in an immovable state. Changes in the position of the solar module should be done once every half hour with a slope angle of </em>+5<sup>0</sup><em> from the initial position of the clock change. At the position of the solar module is not moving, the maximum power is at 12:30 a.m. which is 5.129 watts</em></p> Syarif Hidayat Agung Hariyanto Ridha Yasser ##submission.copyrightStatement## 2019-10-06 2019-10-06 8 2 168 179 10.33322/kilat.v8i2.436 Kajian Harmonisa Pada Pemakaian Tenaga Listrik Gedung STT-PLN Jakarta https://stt-pln.e-journal.id/kilat/article/view/547 <p><em>Harmonic is produced by non-linear loads in electrical system.

E-Kinerja is a tool to assess the performance of employees with the status of the State Civil Apparatus (ASN) online in all work units of the Ministry of Agriculture of the Republic of Indonesia. The purpose of this study is to prove that the determinants of the use of E-performance (performance expentancy, effort expentancy, social influence, and facilitating conditions) influence the intention to behave on users (behavioral intention). The number of respondents in this study were 42 ASN in various ranks and classes. The results of the study show that the level of ASN's acceptance of E-Kinerja received a positive response. This can be seen from each average value of the variables in the range of 3.54 - 4.34 (on a scale of 1 to 5) on the questionnaire that has been distributed. In addition it was also found that Social Influence has a positive influence on Behavioral Intention in the use of E-Kinerja. Whereas Habit has a positive influence on Use Behavioral in the use of E-Kinerja in BBVet Maros. As for the Performance Expentancy, Effort Expentancy, and Facilitating Conditions variables on Behavioral Intention, as well as the Facilitating Conditions and Behavioral Intention variables on Use Behavioral, no positive effect was found.<br><br></p> Suparyati Suparyati ##submission.copyrightStatement## 2019-10-07 2019-10-07 8 2 208 218 10.33322/kilat.v8i2.588
