Abstract

The community in Patin Village smokes fish in the traditional way, namely first, the fish to be smoked first, the fish are cleaned, the second the fish is split on the back to clean from dirt, the three fish that have been split will be arranged in the provided place, then fish will be put in the smoking place. Fish smoking device using closed circulation and temperature monitoring system that has been made. The purpose of the study was to compare the time efficiency of the smoked smoked smoked fish in the traditional way and to know the comparison of the smoking process of smoked smoked fish using coconut fiber and tangkos fuel. The results of the tests that have been carried out can be seen the lowest temperature when taking data 1⁄2 hours once produces 50°C and the highest temperature reaches 110°C. The temperature in the smoking room can be seen and monitored by a digital-based temperature controller with the results of testing the water content in the fish not too far away, the highest water content is 50% using Tangkos fuel, the room temperature at the time of testing is the highest at the time of taking with the highest is 110 oC using tangkos fuel and the difference in the consumption of tangkos fuel and coconut fiber has a difference in smoking, one of which is when testing the highest tangkos fuel it spends as much as 25.71 kg, coconut fiber spends the highest 19.42 kg with fish that different.

Abstract

This research aims to enhance operational reliability and prevent cavitation by evaluating and redesigning the pump's suction piping system in accordance with API RP 686 standard. The evaluation involved analyzing existing field data and comparing it against API RP 686, followed by suction pipeline redesign and Net Positive Suction Head Available (NPSHa) calculations for both conditions. The results show the existing NPSHa to be 4.78 meters, slightly below the pump's NPSHr (5 meters), indicating potential for cavitation due to existing piping configuration non-compliance with API RP 686. After redesign, NPSHa significantly increased to 7.27 meters, exceeding the pump's NPSHr, proving the new design effectiveness in eliminating cavitation.

Abstract

Perawatan mesin industri memiliki peran penting dalam menjamin kontinuitas dan efisiensi proses produksi. Penelitian ini bertujuan untuk menganalisis kerusakan pada unit Cooler Fan 5W1K14 milik PT Semen Padang melalui pendekatan predictive maintenance berbasis analisis vibrasi. Cooler fan merupakan komponen krusial dalam sistem pendinginan klinker, sehingga kegagalannya dapat mengganggu keseluruhan proses produksi. Pengambilan data dilakukan menggunakan alat VibXpert dan dianalisis dengan perangkat lunak Omnitrend. Hasil pengukuran vibrasi awal menunjukkan nilai amplitudo yang melebihi ambang batas standar ISO 10816, khususnya pada titik B2 arah horizontal dengan nilai 8,94 mm/s, yang menandakan adanya kelonggaran mekanis (mechanical looseness). Spektrum vibrasi mengonfirmasi adanya harmonik yang menjadi indikator utama kerusakan pada bearing. Setelah dilakukan penggantian bearing tipe SKF 22216 EK/C3 dan housing bearing, serta pelumasan dan pengukuran ulang, nilai vibrasi menurun secara signifikan ke zona aman, dengan nilai tertinggi 3,82 mm/s. Hasil ini menunjukkan bahwa metode analisis vibrasi efektif dalam mendeteksi dan menanggulangi kerusakan pada mesin berputar. Penelitian ini diharapkan dapat menjadi referensi bagi industri dalam mengoptimalkan strategi pemeliharaan mesin secara prediktif untuk meminimalkan downtime dan biaya operasional.
