Abstract

Meningkatnya tingkat kebutuhan masyarakat terhadap energi listrik menyebabkan perusahaan penyedia energi listrik harus memperhatikan tingkat pelayanan dan kualitas energi listrik yang disalurkan dari pembangkit sampai ke konsumen. Tujuan dari penelitian ini adalah menghitung indeks keandalan SAIFI, SAIDI, CAIFI, CAIDI, ASAI, ASUI, ASIFI dan ASIDI sistem distribusi 20 kV di PT. PLN (Persero) UP3 Yogyakarta. Pada penelitian ini menggunakan metode analisis perhiungan matematis untuk mendapatkan hasil indeks keandalan serta menganalisis penyebab gangguan sampai terjadinya pemadaman. Berdasarkan hasil perhitungan yang telah dilakukan nilai keandalan di Rayon UP3 Yogyakarta yaitu SAIFI = 0,98 kali/gangguan/tahun, SAIDI = 0,96 jam/gangguan/tahun, CAIFI = 1,07 kali/gangguan/tahun, CAIDI = 1,005 kali/gangguan/tahun, ASAI = 0,99989 atau 99,989%, ASUI = 0,00010, ASIFI = 10,52 kali/gangguan/tahun dan ASIDI = 14,52 jam/gangguan/tahun. Hal ini dapat dikatakan bahwa nilai SAIFI dan SAIDI masih dikatakan andal sesuai standarisasi SPLN 68-2 : 1986. Beberapa faktor yang menjadi penyebab menurunnya tingkat keandalan yaitu faktor tegangan distribusi, kerapatan beban, lingkungan fisik, cuaca dan umur Kata kunci:  Keandalan, Sistem Distribusi, SAIFI, SAIDI

Abstract

Perhatian akan pengembangan energi terbarukan semakin meningkat dikarenakan polusi lingkungan yang semakin memburuk serta masalah kekurangan energi. Salah satu pengembangan energi terbarukan yang ada di Indonesia adala PLTH Pantai Baru yang terletak di Desa Poncosari, Srandakan, Bantul. Umumnya, pembangkit listrik yang menggunakan sumber energi terbarukan memiliki kelemahan yaitu sangat bergantung pada kondisi alam. Hal yang sama pun terjadi pada PLTH Pantai Baru. Selain itu, juga perlu diketahui apakah daya yang dibangkitkan mampu memenuhi kebutuhan beban yang ada. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kuantitatif. Menurut Walliman (2011: 10), penelitian deskriptif merupakan penelitian yang bergantung pada kegiatan observasi dengan tujuan untuk mengumpulkan data. Data-data yang dikumpulkan berupa data tegangan, arus, dan daya dari PLTH Pantai Baru. Proses pengumpulan data dilakukan selama tiga hari dengan tujuan untuk mendapatkan variasi kondisi lingkungan dan beban. Data-data tersebut kemudian akan dibandingkan dengan hasil simulasi melalui aplikasi Homer. Hasil penelitian yang telah dilakukan yaitu pada hari pertama daya yang dihasilkan PLTH Pantai Baru sebesar 74.204,05 W dengan efisiensi 52,07%. Hari kedua sebesar 55.393,45 W dengan efisiensi 38,87%. Hari ketiga sebesar 40.250,47 W dengan efisiensi 28,25%. Sementara itu, hasil simulasi hari pertama sebesar 80.656,88 W, hari kedua sebesar 67.228,42 W, dan hari ketiga sebesar 61.646,48 W.

Abstract

Public street lighting is a complement to the road and is placed on the left or right side of the road or in the middle of the median of the road to illuminate the road. The public street lighting that has been operating is usually rarely maintained, and problems will arise in the street lighting that can reduce the illumination value. This study aims to determine the illumination value, whether it is the SNI 7391:2008 standard or not, by means of measurements and simulations on the Jenderal Sudirman Pemalang road. measurement using a digital lux meter (AS803) and simulation using the software DIALux evo 10.1. Based on simulation results with the SNI 7391:2008 standard and an illumination value of 11-20 lux, the study recommends replacing the installed lamp with a 70 W LED lamp. The result of this study is that replacing a 70 W LED lamp can reduce the cost of electrical energy consumption by Rp 3,037,338 and reduce electrical power consumption by 2,102.4 kWh

Abstract

This study aims to enhance the competency of vocational high school students in automotive air conditioning (AC) maintenance by developing a practical learning module. Conducted at SMK Al Asror Semarang, this research utilized the ADDIE development model, encompassing Analysis, Design, Development, Implementation, and Evaluation phases. The analysis identified inadequate facilities and infrastructure as significant factors contributing to students’ low achievement levels. To address this issue, a practical learning module was designed based on the Indonesian National Work Competency Standards (SKKNI) and validated by subject matter and media experts. The implementation involved 29 students who participated in both pre- and post-competency assessments. The module’s practicality was also evaluated in terms of usability, clarity, relevance, and instructional design. In the final stage, students underwent a practical AC maintenance test assessed by external industry professionals. The results demonstrated a substantial improvement in students’ competencies, indicating that the developed module is not only effective but also a valuable instructional resource for enhancing HVACR learning outcomes in vocational education settings.

Abstract

Teacher performance refers to the success of teachers in creating a directed and effective learning process. Factors that influence teacher performance include academic supervision, communication, participatory decision-making, and school climate. In practice, supervision is not always implemented effectively, and communication between principals and teachers does not consistently run harmoniously. This study aims to examine the influence of academic supervision, communication, and participatory decision-making on teacher performance, with school climate as a moderating variable. The research employed a quantitative survey design. Data were collected using questionnaires and documentation. Questionnaires gathered information related to academic supervision, communication, participatory decision-making, and school climate, while documentation was used to obtain Teacher Performance Assessment (PKG) data. The sample consisted of 114 civil servant (PNS) teachers and principals from four public junior high schools in Banyumanik Sub-district, selected using purposive sampling. The findings show that academic supervision, communication, and participatory decision-making each have a significant effect on teacher performance. School climate does not have a direct significant effect on performance, but it strengthens the influence of academic supervision and communication on performance. However, it does not moderate the influence of participatory decision-making. The study recommends providing opportunities for teachers to engage in decision-making and fostering a positive, supportive school climate to improve performance

Abstract

The digital competence of teachers is a crucial aspect in supporting the success of technology-based learning implementation. However, at SMK Merdeka Ulujami, issues were found regarding the low use of effective digital media in the learning process, mainly due to limited training and the lack of integrated media. This study aims to develop a website-based Learning Management System (LMS) as a solution to improve the digital competence of teachers. This research is a type of R&D with the development model being ADDIE. The LMS was developed using the WordPress platform and the Tutor LMS plugin, designed to support blended learning. The research was conducted at SMK Merdeka Ulujami with a total of 20 teachers as participants. Normality testing was conducted using the Shapiro-Wilk method, which showed normal results. Data analysis used paired sample t-tests and Normalized Gain. The results showed a significant improvement in the digital competence of teachers after using the LMS, with a Normalized Gain score of 0.93 or 93%, which is categorized as effective. Observations and interviews indicated that the LMS helped teachers manage digital classrooms efficiently and in a structured manner. However, challenges remain, especially with older teachers who are less familiar with software, highlighting the need for continuous support.
