Abstract

The purpose of this research to know and analysis for income factor with parsial and simultaneous, price and rate, amount the tools use the electric, the individual into family and the wide of building towards electric demand in consumer household in Guntarano village of Tanantovea district of Donggala Regency. The research population are 60 households that have electric network in PLN (state electric company). Remember the research population is limited relatively, that only 60 households that have electric network from PLN, so that the samples are all population in research or use a census technique where that all population member get opportunity as the sample. The collecting of primary and secondary data have been done by questionnaire and documentation. Thus, hypothesis test in research use multiple linear regression analysis method, the result of research indicate that income factor, price and rate, amount the tools use the electric, the individual into family and the wide of building with parsial and simultaneous which affect with significance towards the household electric demand in Guntarano village of Tanantovea district of Donggala Regency, and there are the factor that support and constrain of household electric demand in Guntarano village of Tanantovea district of Donggala Regency.

Abstract

Energi listrik merupakan salah kebutuhan masyarakat modern yang sangat penting dan vital. Ketiadaan energi listrik akan sangat mengganggu keberlangsungan aktivitas manusia. Oleh karena itu kesinambungan dan ketersediaan energi listrik perlu dipertahankan. Bagi masyarakat yang tinggal di daerah perkotaan dan sekitarnya, energi listrik tidaklah menjadi masalah. Karena energi listrik yang disediakan oleh Perusahaan Listrik Negara (PLN) telah tersedia di kawasan tersebut. Namun bagi masyarakat yang tinggal di daerah-daerah pedalaman dan pulau-pulau terpencil, energi listrik merupakan suatu masalah besar. Karena jaringan listrik PLN belum menjangkau pada daerah tersebut. Solusi yang tepat untuk mengatasi ketiadaan energi listrik di daerah tersebut adalah mengubah  cahaya matahari yang melimpah menjadi energi listrik menggunakan teknologi photovoltaic. Sistem penyediaan listrik seperti ini disebut Pembangkit Listrik Tenaga Surya (PLTS). PLTS yang digunakan khusus untuk perumahan disebut Solar Home System (SHS). Pada makalah ini dibahas metoda perancangan pembangkit listrik tenaga surya untuk perumahan. Hasil dari perancangan ini diharapkan menjadi acuan bagi calon pengguna maupun praktisi listrik agar diperoleh kesesuaian antara kebutuhan energi, harga, dan kualitas yang tepat.

Abstract

Paper ini membahas sebuah teknik untuk membantu para perancang catu daya dalam memodelkan dan merancang secara akurat lup kendali sebuah chopper DC mode switching. Tiga komponen utama dari lup kendali catu daya, yaitu: rangkaian daya, modulator lebar pulsa, dan penguat galat, dimodelkan dengan penekanan pada rangkaian daya. Rangkaian daya dimodelkan dengan metoda Model Sakelar PWM, yang lebih sederhana dibandingkan analisis dengan metoda state-space average. Jenis PWM yang dimodelkan adalah PWM mode tegangan

Abstract

This paper presents a method to control Permanent Magnet Synchronous Motor (PMSM) at high speed above the based speed. To control PMSM from zero speed up to base speed, the armature voltage of the motor may be varied up to maximumvoltage allowed of the inverter used. In this region the stator voltage will increases with the increases of motor speed reaches the based speed, motor voltage cannot increase anymore because of saturation and consequently motor speed cannot be increase more highly. In order motor to control the motor above base speed, it is can be done by weakening the field flux of the rotor. As the rotor made of permanent magnet, then filed weakening control cannot be done directly. The control of field-weakening effect is done by controlling stator current vector of direct axix, which is variable with speed

Abstract

The success of pencak silat athletes is influenced not only by mastery of techniques and physical condition, but also by environmental support, especially parental involvement through emotional, informational, instrumental, and assessment support that can strengthen motivation, discipline, and enthusiasm for training and competing. This study focuses on analyzing the influence of parental support on the achievements of Pencak Silat athletes from PSHT Ranting Mojosari Mojokerto in 2026 using a quantitative approach and quantitative descriptive design. The study involved all parents of PSHT Ranting Mojosari athletes as the population, with 30 respondents determined using a saturated sampling technique. Data were collected through a Likert-scale questionnaire, then analyzed using validity tests, reliability tests, descriptive analysis, normality tests, linearity tests, and simple linear regression tests assisted by SPSS 25. Data distribution shows that parental support is in the moderate category at 63.3% and athlete achievement is in the moderate category at 66.6%. The regression analysis yielded a significance value of 0.000 (p < 0.05), a correlation coefficient (R) of 0.987, and a determination coefficient (R²) of 0.975, confirming the positive and significant influence of parental support on athlete achievement, contributing 97.5%, while 2.5% was influenced by other factors outside the study. These findings indicate that increased parental support is in line with increased athlete achievement, so family involvement needs to be strengthened in the sports coaching process.
