Abstract

Abstrak Semakin pesatnya pertumbuhan penduduk, maka kebutuhan energi listrik juga semakin meningkat. Dalam penyaluran tenaga listrik dari sumber tenaga listrik ke konsumen yang letaknya berjauhan selalu mengalami terjadinya kerugian berupa rugi-rugi daya dan jatuh tegangan. Penelitian ini dilakukan pada Penyulang Lumumba di PT. PLN Ngagel Surabaya yang bertujuan untuk memperbaiki kualitas daya terhadap rugi-rugi daya dan drop tegangan dengan pemasangan kapasitor bank pada penyulang dengan mensimulasikan pada software ETAP 12.6. Besar kapasitor bank yang dibutuhkan untuk mengkompensasi daya reaktif pada penyulang Lumumba ialah sebesar 700,52 kVAr. Setelah dilakukan perbaikan dengan pemasangan kapasitor bank dengan simulasi pada ETAP 12.6, nilai rugi-rugi daya pada penyulang Lumumba dapat diturunkan dari 26,5 kW menjadi 18,6 kW dan 75,7 kVAr menjadi 53,1 kVAr. Dengan faktor daya awal 0,8 menjadi rata-rata sebesar 0.95 pada sistem dan drop tegangan menurun dari 2,99%menjadi rata-rata sebesar 1,79% dimana drop tegangan paling besar pada sistem jaringan distribusi terjadi pada trafo BD179 dari 4,33% menjadi 2,58%. Kata Kunci: kualitas daya, rugi-rugi daya, drop tegangan, kapasitor bank, faktor daya, ETAP 12.6. Abstract By increasing population growth, the demand for electrical energy is increasing. In the distribution of electricity from a source of electricity to consumers which always at a loss in the power losses and voltage drops. This research was conducted at Lumumba Feeders at PT. PLN Ngagel Surabaya which aims to improve the quality of power towards power losses and voltage drop by installing bank capacitors using ETAP 2.6 simulation. Bank capacitors needed to compensate for the reactive power of Lumumba feeders are 700,52 kVAr. After repairs with the installation of bank capacitors using ETAP 12.6 simulation, the value of power losses for Lumumba feeders can be reduced from 26.5 kW to 18.6 kW and 75.7 kVAr to 53.1 kVAr. With a power factor of 0.8 being an average of 0.95 on the system and a voltage drop decreasing from 2.99% to an average of 1.79% where the greatest voltage drop in the distribution system occurs on the BD179 transformer from 4.33% to 2.58%. Keywords: power quality, power losses, voltage drop, bank capacitors, power factor, ETAP 12.6.

Abstract

Sistem pentanahan merupakan sistem yang dapat mengamankan makhluk hidup dari sengatan listrik dan mengamankan komponen-komponen instalasi dari bahaya tegangan/ arus abnormal. Sistem pentanahan yang baik mempunyai nilai resistansi yang kecil. Salah satu usaha untuk menurunkan resistansi pentanahan adalah dengan perlakuan khusus pada tanah (soil treatment) yaitu memberikan zat tertentu kedalam tanah. Pada penelitian ini digunakan abu terbang sebagai media pada soil treatment. Tujuan dari penelitian ini untuk memeroleh informasi pengaruh penambahan abu terbang terhadap nilai resistansi pentanahan elektroda batang berlapis tembaga. Metode yang digunakan dalam penelitian ini adalah metode eksperimen dan data diolah menggunakan statistik deskriptif. Hasil penelitian menunjukkan pemberian abu terbang dengan takaran 40% dari kedalaman penanaman elektroda dapat mengurangi nilai resistansi pentanahan yaitu sebesar 1,82 Ω menjadi 1,18 Ω. Untuk mencapai resistansi kurang dari 1 Ω, tanpa pemberian abu terbang membutuhkan kedalaman penanaman sebesar 12 meter, sedangkan dengan pemberian 40% abu terbang membutuhkan kedalaman sebesar 7 meter.Kata kunci : abu terbang, resistansi pentanahan, sistem pentanahan.

Abstract

The learning process carried out by teachers in schools is a very important activity in improving the quality of education. The learning process carried out by the teacher cannot be separated from the use of instruments in the form of questions that will be presented to determine the level of students' critical thinking. The use of the right questions is very important to support the learning process in the future. One of them is a question based on the partial credit model to determine the level of critical thinking of students which is considered suitable to be implemented in the learning process. This study aims to determine the validity and reliability of the partial credit model instrument in the subject of electrical equipment repair and to determine the position of respondents and items on the wright map. The research method used is an experimental method in the form of a One-Shot Case Study. The experimental subjects were students of class XI TITL 2 at SMK Negeri 1 Kediri. Then to analyze and process data using ministep software. The results showed that the partial credit model based question instrument was declared valid for use with the unidimensionality test results obtained by the raw variance explained by measures measurement result of 40.4%, the partial credit model based item instrument was stated to be reliable with the item reliability rating result of 0.93 and 0.94, obtained person reliability values of 0.68 and 0.70, and obtained values from crombach alpha of 0.69, analysis of the wright map obtained item measures and person measures on the wright map showing the distribution of item difficulty and person abilities with limitations logit values 2 to -2 with equivalent person and item positions, so it can be concluded that the instrument can be used to measure the person's ability level.

Abstract

Quality education is a crucial foundation for sustainable development, as emphasized in the Sustainable Development Goals (SDGs), particularly the fourth goal regarding inclusive and quality education. In the era of Industry 4.0, education must rapidly adapt to technological changes and enhance educators' competencies to equip the younger generation with future skills. Sekolah Indonesia Kuala Lumpur (SIKL) has adopted the K-13 Curriculum with the Living Curriculum concept to align learning with students' real needs and global challenges. Despite implementing various innovations, SIKL faces challenges in implementing the new Merdeka Curriculum, which offers flexibility but requires adjustments in teaching methods and evaluation. This knowledge gap threatens the quality of education and the development of 21st-century skills for students. To address this, a team of lecturers from Universitas Negeri Surabaya conducted a Community Service Program (CSP) aimed at enhancing teachers' competencies in effectively implementing the Merdeka Curriculum. The implementation method includes online training divided into three sessions: Focus Group Discussion (FGD), presentation of learning models, and evaluation techniques. The CSP activities resulted in a significant increase in teachers' understanding and skills, with average scores rising from 68 to 86, and improvements in utilizing technology and data-based evaluation. This activity successfully strengthened teachers' competencies, making them better prepared to meet global educational demands and advance teaching quality at SIKL.

Abstract

Abstrak: Perubahan radikal dalam sains pada awal Eropa modern berpengaruh amat besar terhadap riset-riset praktis dan konsep berikutnya tentang masyarakat dan manusia itu sendiri. Pola pengembangan yang khas dari sebuah kematangan sains adalah transisi berturutan dari satu paradigma ke paradigma lain melalui proses revolusi. Sains pada dasarnya lebih dicirikan oleh paradigma dan revolusi yang menyertainya. Konsep sentral Kuhn adalah apa yang dinamakan dengan paradigma. Istilah paradigma identik dengan “skema” dalam teori belajar. Skema adalah suatu struktur mental atau kognisi yang dengannya seseorang secara intelektual beradaptasi dengan lingkungan sekitarnya. Skema ini akan beradaptasi dan berubah seiring perkembangan mentalnya. Teori belajar, dimana pembelajar mengkonstruksi “skemaskemanya” dikenal dengan konstruktivisme.
