Abstract

Electricity needs for each year has increased, this is due to an increase in people's lives. Reliability is an important factor in the operation of distribution system and is an important factor in the continuity of the waiter to the consumer. Several parameters are used as reference to megukur level of reliability of a distribution system that is SAIFI (avarage interuption of frequency index system) is a calculation of the number of failures or disruptions average - average one year, SAIDI (System of interruption Duration Index) index median duration - average system interruption during the year. In this study was also performed calculations eens (Expected Energy Not Supplied) This calculation is done because of disturbance at each feeder there is energy that can not be channeled, it can happen losses. Based on the calculation and analysis that the reliability index is obtained there are some feeder Rayon Panam categorized as not reliable because it has a high SAIFI value not in accordance with the target SPLN No. 68-2 1986 and IEEE std 1366-2003. Energy losses that can not be distributed annually sizeable each feeder. This indicates a feeder located at Panam Rayon considered less reliable, to the need for repairs and maintenance

Abstract

Train is one of transportation which supports the mobilization of society. Futhermore, it is affordable and comfortable so that people prefer using it. One of trains which is usually used by many people is KRDE or electric diesel railway, which is an innovation of technology in PT. INKA based on railway industry. It is one of railway that need electricity as the main source of energy that comes from alternator. it will handle all power of load needs on KRDE like as propulsion and auxiliary load. Therefore, the fluency of KRDE is affected by electrical system of the railway, which is mostly affected by propulsion load because it needs bigger power than auxiliary load. In this research presents about losses calculation on KRDE that are Three- phase rectifier, Variable Voltage Variable Frequency (VVVF) inverter and Three phase induction motor. Three phase rectifier and VVVF inverter will simulated by PSIM software to understand how the circuit work. The results of this research are explain about the number of loss energy in three phase rectifier is 21,6 Watt. In VVVF inverter and three induction motor, there are five samples. From analysis of the samples result that VVVF inverter has the highest efficiency 95,53% with loss energy 19,992 KW, which on 645 Volt about output voltage and 90 Hz about output frequency. In three phase induction motor, 91, 426% is the highest efficiency and it has 18,211 KW at loss energy, which on 635 Volt about input voltage and 36,38 Hz about input frequency. Then, the highest efficiency of propulsion system is 94,59% and 53,38 KW about loss energy, which on 635 Volt about input voltage and 36,38 Hz about input frequency in induction motor.

Abstract

Depending on persuasive statistics, the increasing prevalence of diabetes worldwide is a huge challenge for individuals, families, and nations. According to International Diabetes Federation (IDF) projections, the number of adults with diabetes is expected to rise by an astounding 46% by 2045, to reach 783 million, or one in eight. In response to this growing concern, this research explores the implementation of the Naive Bayes algorithm for predicting diabetes, employing comprehensive data cleansing and randomization techniques. A systematic evaluation of the model's performance is conducted using several training and testing split ratios (65:35, 75:25, 85:15). The outcome showed that the model performed best at the 65:35 split ratio, with accuracy reaching its maximum of 88.16%, precision 0.883, recall 0.881, and f1-score 0.882.

Abstract

Pada era sekarang ini perkembangan ilmu pengetahuan dan teknologi semakin canggih sehingga manusia mudah mengakses setiap aplikasi digital dalam handphone dan laptop. Namun, sebagian masyarakat tidak banyak mengetahui dan mengakses aplikasi tersebut, karena kurangnya pengetahuan. Pengabdian ini ditujukan pada masyarakat Bulu, Lendah, Kulonprogo Yogyakarta. Tujuan kegiatan ini adalah meningkatkan keilmuan keislaman masyarakat dalam hal membaca Al-Qur’an agar sesuai kaidah tajwid melalui aplikasi digital Al-Qur’an. Metode yang digunakan adalah metode kualitatif yang bersifat Participatory Action Research dengan ceramah dan praktik aplikasi digital. Hasil kegiatan ini adalah: pertama, meningkatnya kecintaan dan semangat membaca Al-Qur’an dengan mudah dan mandiri. Kedua, masyarakat dapat mempraktikkan cara membaca Al-Qur’an dengan aplikasi digital Quran secara offline dan online. Ketiga, sikap tumbuh semangat dalam meningkatkan keilmuan pemahaman dalam menerjemahkan Al-Qur’an, sehingga mereka lebih banyak berinteraksi dengan Al-Qur’an. Keempat, pelatihan melalui aplikasi digital Quran tersebut mudah diakses oleh siapa pun, kapan pun dan di mana pun, maka kemandirian masyarakat menjadi lebih tinggi untuk dapat belajar Al-Qur’an daripada belajar langsung kepada guru. Kelima, pelatihan aplikasi digital Quran setidaknya dapat memberikan pengetahuan kepada masyarakat tentang penting-nya aplikasi digital Quran dalam mempelajari Al-Qur’an sebagai satu sumber ilmu pengetahuan yang komprehensif. Maka IPTEKS ini sangat membantu masyarakat dalam membaca dengan benar sesuai kaidah tajwid, memahami, dan mengamalkan isi kandungan Al-Qur’an dalam aktivitas keseharian.
