Pisang uli adalah jenis pisang yang banyak dijumpai di Indonesia terutama di Pulau Jawa. Pemanfaatannya selama ini selain dimakan secara langsung adalah diolah menjadi pisang goreng. Kegiatan yang dilakukan ini bertujuan mencari alternatif pengolahan dengan metode baru pisang uli yaitu dengan membuat pisang crispy dan tambahan topping. Metode yang dilakukan adalah dengan tahapan persiapan yaitu pengamatan singkat sumber-sumber pisang uli dan pemanfaatannya selama ini. Setelah itu pelaksanaan pembuatan pisang uli crispy. Hasil dari kegiatan ini disajikan dalam urutan proses produksi dan perhitungan biaya pembuatan pisang crispy yang bisa dimanfaatkan oleh warga Di Cileungsi dan sekitarnya
Penelitian dilakukan di bagian assembling panel listrik bulan November 2021. Proses assembling merupakan proses perakitan komponen listrik menjadi panel listrik. Permasalahan yang terjadi adalah pada bulan Desember 2021 ditemukan 94 unit produk cacat dari total produksi 301 unit. Ada tiga jenis cacat yang terjadi yaitu cat yang mengelupas, lubang pada panel, fungsi. Hal ini dilakukan untuk meningkatkan kualitas produksi panel listrik. Metode yang digunakan adalah DMAIC (define, measure, analyze, improve and control). Dari hasil perhitungan didapat Level Sigma sebesar 2.75 dengan nilai DPMO (Defect Per Million Opportunity) sebesar 104.097 unit yang artinya proses produksi panel listrik masih berjalan dengan baik, namun perlu melakukan perbaikan secara terus-menerus untuk mencapai level 6 Sigma. Beberapa implementasi dilakukan oleh perusahaan berdasarkan usulan tindakan perbaikan yang telah dibuat. Implementasi tersebut berdampak pada kenaikan Level Sigma dan kenaikan nilai DPMO (Defect Per Million Opportunity)
Generator Set Unit that operates in the PLTD, during operation there is a knocking sound at cylinder position # 14, after checking and removing the injector there is diesel in the combustion chamber and indicated glowing in the exhaust manifold. The purpose of this study is to determine the root causes of knocking and diesel fuel in the combustion chamber. This research method uses oil sample testing to be tested in the laboratory. The results of the analysis of oil contaminated with diesel fuel are caused by diesel oil flowing into the pan oil and after checking the cylinder head crack (groove-shaped) is found on the side of the injector seal holder, when the unit is not operating the diesel flows into the combustion chamber and into the oil reservoir. The groove in the cylinder head is formed, caused by a hard injector seal caused by fuel temperature and high water temperature. The solution of this research is that the pressure on the fuel return from the engine should not exceed 27 kPa, while the maximum fuel temperature is 66 °C (150 °F), and what needs to be done is an improvement of diesel cooling and routine radiator maintenance.
Damage to the main bearing components on the generator set unit operating in the PLTD to supply power to PLN. Based on the initial indication of engine blow-by and high vibration in the damper area of the service meter unit (SMU): 25555. The purpose of this study is to determine the root cause of the main bearing damage that changes shape and color in the diesel engine generator set. The method used in this research is a visual inspection and removing engine components. The results and discussion of the research obtained changes in the shape and color of the main bearing, starting from the main bearing material (rotating) spalling so that it rubs against the main journal. The friction that occurs causes changes in the shape of the main bearing and causes the main bearing to rotate. The keywords on the main bearing are released due to thinning so that the main bearing rotates and closes the supply of lubricating oil to the main and rod bearings. Based on the analysis, the most likely cause of adhesive wear on Main Bearing #1 is crankshaft misalignment towards the front of the engine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
