Abstract

Pada masa pelaksanaan proyek konstruksi sering terjadi ketidaksesuaian antara jadwal rencana dan realisasi di lapangan yang dapat mengakibatkan pertambahan waktu pelaksanaan dan pembengkakan biaya pelaksanaaan sehingga penyelesaian proyek menjadi terhambat. Maka dari itu diperlukan percepatan penyelesaian proyek, alternatif percepatan dapat berupa penambahan jam lembur, pengunaan alat yang produktif, penambahan jumlah pekerja, penggunaan material yang cepat pemasangannya dan metode konstruksi yang lebih cepat. Pelaksanaan yang mengalami keterlambatan perlu dilakukan percepatan. Analisis yang dilakukan pada penelitian ini dengan mempersingkat waktu pelaksanaan proyek dengan alternatif penambahan 3 jam kerja (lembur) pada kegiatan-kegiatan kritis yang didapat dari analisi jaringan kerja berupa CPM. Hasil yang didapatkan adalah durasi setelah percepatan yaitu 18 minggu atau 126 hari kerja atau lebih cepat 18,18% dari durasi normal yaitu 22 minggu atau 154 hari kerja, sedangkan biaya upah tenaga kerja setelah percepatan mengalami peningkatan dari biaya normal sebesar Rp. 47.750.000,00 menjadi Rp. 88.737.716,76.

Abstract

Organic waste management in Indonesia faces significant challenges due to the high greenhouse gas emissions produced. In 2020, greenhouse gas emissions from waste management in Indonesia especially the waste sector contributes around 3.2% of total global emissions. The use of organic waste shredders is one solution to minimize waste volume; althought still heavily rely on conventional energy, which is not environmentally friendly. This study aims to evaluate the implementation of solar photovoltaic (PV) technology in organic waste shredding machines to enhance energy efficiency and reduce environmental impacts. An experimental approach was used in this research. Data were collected through measurements of energy generated by the solar cells, energy consumed by the machine, and the organic waste shredding output processed into compost fertilizer. The results showed that use of solar cells could generate an average of 5.8 kWh of energy per day, with machine energy efficiency reaching 72%. Compared to conventional energy, the use of solar cells increased the shredder machine's productivity to 25 kg/hour and reduced greenhouse gas emissions by up to 70%. Additionally, machine operating time increased by 20% compared to machines using conventional energy.  This increase is due to the solar cell technology itself. In conclusion, application of solar cell technology in organic waste shredders not only improves operational efficiency but also significantly contributes to carbon emission reduction. The research  contribution is to offer concrete solutions that support the achievement of national and global carbon emission reduction targets, as well as creating a waste management model that can be applied in various regions in Indonesia and the world.

Abstract

Sistem distribusi sekunder digunakan untuk menyalurkan tenaga listrik dari gardu distribusi ke beban-beban yang ada di konsumen. Salah satu yang menyebabkan kerja transformator distribusi berkurang adalah adanya arus pada penghantar netral yang menyebabkan adanya rugi-rugi penghantar yang diakibatkan oleh ketidakseimbangan beban pada jaringan distribusi tegangan rendah di Jayapura. Metodologi penelitian yang diterapkan dengan cara melakukan pengambilan data arus, data trafo, data gambar single line yang diperoleh dari PT. PLN (PERSERO) Rayon Abepura. Hasil analisis perhitungan menunjukkan bahwa besarnya rugi-rugi pada LWBP berkisar antara 0,001 KW – 48,10 KW dan WBP rugi-rugi pada penghantar netral berkisar antara 0,01 KW – 18,81 KW. Presentase ketidakseimbangan beban pada Luar Waktu Beban Puncak terbesar pada gardu trafo ABE322 sebesar 33,33 % dan terendah pada gardu trafo ABE347-K sebesar 1,34 %. Sedangkan presentase ketidakseimbangan beban pada Waktu Beban Puncak terbesar pada gardu trafo ABE263-1 sebesar 33,98 % dan terendah pada gardu trafo ABE007-1 sebesar 1,89 %.

Abstract

The urgency of PNBP community service in 2024 is that teachers need to implement mobile learning applications as interactive multimedia learning media for science on solar system material for grade VI elementary school students. This is necessary because students find it difficult to understand the solar system subject matter and do not know what planets are in the solar system using textbook teaching materials and students get bored quickly and are less interested because students only imagine the solar system based on the teacher's explanation on the board. The purpose of this community service is the transfer of science and technology to implement mobile learning applications as interactive multimedia learning media for science on solar system subject matter for grade VI elementary school students. Community service activities are carried out using lecture methods, discussions, questions and answers, demonstrations and practices for using mobile learning applications for science, as well as evaluation of community service activities. The targeted output is that elementary school students can use interactive learning media for mobile learning applications for science to improve the quality of learning solar system material and the results of community service activities in the form of articles published in community service journals.

Abstract

This study presents a contextually tailored off-grid hybrid energy system consisting of solar photovoltaic (PV), diesel generator (DG), and battery storage, designed for the remote mountains village of Jifak in Papua, Indonesia. The objective is to evaluate the technical, economic, environmental, and social feasibility of electrification in underserved regions. A comprehensive feasibility analysis was conducted using HOMER software, incorporating realistic communal load profiles, National Aeronautics and Space Administration (NASA) climate data, and field-based social assessments. The optimized system achieved a net present cost (NPC) of $10.43 million, a levelized cost of energy (LCOE) of $0.5095/kWh, and annual emissions of 7,965 kg CO₂. Sensitivity analysis was performed on fuel cost, discount rate, and inflation rate to assess system robustness. Beyond the technical metrics, the study assessed the socio-economic impacts of electrification, revealing improvements in lighting quality, education, productivity, income generation, and environmental awareness. The findings provide a replicable model and decision-making framework for policymakers and practitioners aiming to deploy low-carbon, sustainable electrification strategies in similarly remote regions.
