Abstract

Penelitian ini bertujuan untuk menganalisis performansi kabel N2XY pada sistem tiga fasa tegangan rendah dengan fokus utama pada pengaruh jatuh tegangan yang terjadi. Masalah jatuh tegangan dalam sistem distribusi listrik seringkali mengakibatkan turunnya kualitas pasokan daya, sehingga memerlukan analisis menyeluruh terhadap parameter sistem yang digunakan. Metode penelitian ini mencakup pengukuran langsung di lapangan, perhitungan manual menggunakan rumus dasar teknik listrik, serta simulasi dengan perangkat lunak ETAP 12.6.0 untuk memvalidasi hasil analisis. Hasil penelitian menunjukkan bahwa pada jarak 1,3 km dengan kabel N2XY berpenampang 4 x 70 mm² dan beban total sebesar 20,7 kW, diperoleh jatuh tegangan sebesar 33,3 V (8,31%) berdasarkan pengukuran, 33,89 V (8,47%) dari perhitungan, dan 25,8 V (6,5%) melalui simulasi ETAP. Disarankan untuk memperbesar penampang kabel guna meminimalisir jatuh tegangan dan menjaga kestabilan sistem distribusi daya listrik

Abstract

Behavior is an organism's response to internal and external stimuli. By definition, behavior is an action performed by a living being in reaction to a stimulus. A consistent pattern of response to specific stimuli is categorized as behavior. An animal's ability to survive is reflected in these behavioral patterns. Each animal species has a unique way of acting, corresponding to their anatomical structure. Therefore, it is crucial to study animal behavior patterns in depth, given their critical role in maintaining ecosystem sustainability and balance. This research aims to investigate how the provision of stimuli to animals generates responses in the form of behavioral patterns towards their environment. By writing this research, it is hoped that the general public can understand more about animal behavior patterns. This research method is a literature review or literature review through several research articles, this review is done by searching from a database in the form of Google Scholar and obtaining 5 research articles.

Abstract

Penelitian ini bertujuan menganalisis perkembangan dan arah penelitian mengenai pengelolaan ekosistem mangrove dalam mendukung keberlanjutan wilayah pesisir selama periode 2019–2025. Pendekatan yang digunakan adalah Systematic Literature Review (SLR) berdasarkan pedoman PRISMA 2020. Sebanyak 15 artikel jurnal ilmiah nasional dan internasional diseleksi dari basis data Scopus, ScienceDirect, SpringerLink, dan Google Scholar. Hasil analisis menunjukkan bahwa tema penelitian mengalami pergeseran signifikan dari konservasi struktural menuju integrasi antara ekologi, sosial-ekonomi, dan kebijakan. Lima tema utama yang diidentifikasi adalah: (1) ekologi dan blue carbon; (2) restorasi dan rehabilitasi; (3) sosial-ekonomi dan kelembagaan; (4) kebijakan dan tata kelola; serta (5) teknologi dan monitoring. Pengelolaan berbasis masyarakat, inovasi pemantauan digital, dan mekanisme pasar karbon biru muncul sebagai pendekatan strategis yang efektif. Namun demikian, ditemukan sejumlah kesenjangan penelitian, antara lain kurangnya studi longitudinal, minimnya data wilayah timur Indonesia, serta lemahnya integrasi kebijakan antar-lembaga. Oleh karena itu, riset ke depan disarankan untuk menggabungkan pendekatan socio-ecological systems dengan penguatan tata kelola dan teknologi partisipatif agar mangrove dapat menjadi fondasi keberlanjutan pesisir dan mitigasi perubahan iklim nasional.
