Abstract

Pompa Sentrifugal adalah mesin untuk menggerakan fluida. Pompa menggerakan fluida dari tempat bertekanan rendah ke tempat dengan tekanan yang lebih tinggi, untuk mengatasi perbedaan tekanan ini maka diperlukan tenaga (energi). Mesin ini merupakan mesin yang sangat penting pada Perusahaan Daerah Air Minum (PDAM) karena menjadi komponen utama sebagai menyalur air. Tujuan penelitian ini adalah mengidentifikasi kegagalan-kegagalan pada pompa sentrifugal dengan menggunakan fault tree analysis (FTA) dan root cause analysis (RCA), serta menggunakan analysis of variant (ANOVA) dan reliability block diagram (RBD) untuk menentukan nilai kehandalan. Mesin pompa sentrifugal terdapat di pabrik Perusahaan Daerah Air Minum (PDAM) Tirtasari, Binjai Kota, Binjai. Pada setiap pabrik ataupun perusahaan manajemen pemeliharaan sangat mempengaruhi produksi dan efisiensi sistem.

Abstract

Penelitian ini dilakukan untuk mengetahui kondisi di dalam ruang bakar turbin gas jenis Silo Chamber dan pendistribusian temperatur dan tekanan di dalamnya dengan menggunakan simulasi ANSYS. Data yang dimasukkan berupa udara kompresi bertekanan 8.5 bar dan temperatur 722 K, serta bahan bakar berupa gas alam (CH4) dengan kecepatan masuk 20 m/s dan temperatur 300 K. Hasilnya adalah temperatur, tekanan, dan kecepatan aliran udara (velocity) tertinggi berada di tengah ruang bakar dimana pada posisi interval 5 < y < 7 m dari sumbu utama.

Abstract

This study explores the implementation of a holistic community service program in Siponjot Village, North Sumatra, aimed at enhancing non-formal education, economic sustainability, and environmental resilience. Through the "Marsiajar Manang Didia Pe" initiative, the program promotes a flexible learning system aligned with local cultural values, addressing gaps in formal education. Key components include training in agricultural practices focusing on coffee and mahogany cultivation alongside the introduction of data-driven decision making tools such as economic mathematical models and QR codes for improved information management. Results indicate improved community engagement, increased agricultural productivity, and enhanced digital literacy. The findings highlight the critical interplay between education, technology adoption, and sustainable practices in fostering community empowerment and resilience against environmental challenges.

Abstract

This study examines the performance of a three-phase decanter centrifuge in separating oil, water, and solids in palm oil mills. Efficient separation is critical to improving crude palm oil (CPO) yield and minimizing losses, yet many mills face challenges such as excessive sludge, unstable emulsions, and oil loss. The objective of this research is to compare the operational performance of decanters at A and B mills and to identify the dominant factors influencing oil loss. A case study approach was employed, combining sampling of light, heavy, and solid phases with operational data analysis and direct observations. The results indicate that PKS A experienced high non-oil solids (NOS) in the feed, which caused excessive oil loss in the sludge, while PKS B faced unstable and high emulsion levels, resulting in greater oil loss in the heavy phase. These findings confirm that decanter performance is highly site-specific, even when identical machines are used. The study concludes that operational strategies must be tailored: reducing NOS in PKS A and controlling emulsions in PKS B. The main contribution of this research is providing empirical evidence of differing decanter challenges across mills, offering practical guidance for optimization. The limitation lies in the scope restricted to two mills, suggesting that future research should include more sites and external variables to develop a comprehensive optimization model.
