Abstract

Fenomena perpindahan panas dua fasa yang terjadi pada celah sempit yang berbentuk pelat pada Untai Uji Beta (UUB) penting untuk dikaji terutama pada saat terjadi kehilangan pendingin (Loos of Coolant) LOCA pada PLTN tipe PWR. Untuk menunjang pengkajian ini diperlukan sistim instrumentasi yang memadai terutama untuk meningkatkan keandalan dan keselamatan operator yang selama ini dilakukan secara manual, yaitu merancang otomatisasi katup bukaan sistem primer pada UUB berdasarkan temperatur pendingin. Tujuan rancang bangun adalah untuk mendapatkan sistem instrumentasi kendali katup yang bekerja secara otomatis sehingga memudahkan peneliti dalam melaksanakan kegiatan eksperimen dengan menggunakan fasilitas UUB. Kegiatan rancang bangun dimulai dengan menentukan modul-modul yang berhubungan dengan parameter besaran fisis yaitu modul NI 9213 (termokopel) untuk meman-tau temperatur dan modul NI 9476 (digital I/O) untuk mematikan dan menyalakan pemanas. Setelah merangkai modul-modul tersebut menjadi satu kesatuan sistem otomatisasi kendali maka dibuat pro-gram kendali menggunakan perangkat lunak LabVIEW 2011. Hasil pengujian menunjukkan bahwa pengaturan temperatur pendingin pada 55 - 60 oC dapat dicapai pada menit ke-28 dimulai dari suhu kamar dan pemanas mati dan pemanas hidup kembali pada menit ke-98. Dengan demikian sistem otomatisasi katup bukaan pada sistem pendinginan sistem primer dapat digunakan untuk kegiatan eksperimen di UUB.

Abstract

Reliabilitas merupakan peluang suatu unit atau komponen akan beroperasi dengan baik dalam jangka waktu tertentu di bawah kondisi pemakaian yang sesuai prosedur tanpa kegagalan. Reliabilitas komponen merupakan peluang komponen mampu hidup atau baru mati setelah waktu tertentu. Reliabilitas komponen dapat dipergunakan untukmenghitung reliabilitas sistem. Perhitunan reliabilitas sistem bergantung pada susunan komponen yang membentuk sistem tersebut. Susunan sistem dalam penelitian ini menggunakan seri terhadap paralel. Komponen elektronika berupa satu resistor dan dua LED yang membentuk lampu PCB. Data yang diambil merupakan waktu kegagalan komponen dan berupa data bangkitan. Untuk masalah ini diambil sebanyak 50 data dari masing-masing komponen. Uji kecocokan distribusi menggunakan metode AndersonDarling, sedangkan taksiran parameter distribusi menggunakan metode median rank regression estimation (MRRE) dan maximum likelihood estimation (MLE). Hasil yang didapat bahwa waktu kegagalan resistor berdistribusi Weibull, waktu kegalan LED1 berdistribusi normal dan waktu kegagalan LED2 berdistribusi lognormal. Estimasiparameter distribusi Weibull menggunakan MRRE didapat gˆ = 15,57 dan qˆ = 42999,12, estimasi parameter distribusi normal menggunakan MLE didapat mˆ = 40068,62 dan sˆ = 451,17 dan estimasi parameter distribusi lognormal menggunakan MLE didapat mˆl  = 10,60 dan sˆl  = 0,01. Secara umum dapat dikatakan bahwa baik untuk reliabilitas komponen maupun   reliabilitas   sistem   dengan   bertambahnya   waktu kegagalan berimplikasi menurunnya nilai reliabilitas.Kata kunci : Reliabilitas, Sistem seri terhadap paralel, Anderson-Darling.

Abstract

The processing of fish, would produce fluid that comes from the process of cutting, washing and processing of products. Fisheries waste, especially wastewater, is usually discharged directly into the environment and caused environmental nuisance. Fishing industry wastewater contains a lot of protein and fat, resulting in nitrate and ammonia values were quite high, so it can be used as raw material for a complete organic fertilizer. In this study, the wastewater derived from cleaning fishes is used as the raw material for liquid fertilizer because its nutrient content is very potentially to be used as a liquid fertilizer. One way to make liquid fertilizer is through fermentation techniques. In this case, it used six (6) variations in the addition of coconut fiber to determine the effect of macro nutrients for making the best liquid fertilizer. The variations were: 0 ml, 100 ml, 200 ml, 300 ml, 400 ml, 500 ml and it was being fermented for 28 days. The amount of coconut fiber that produces the best liquid fertilizer is by adding 100 ml of it which resulting in nutrient macro content of C-organic, nitrogen, phosphorus and potassium, respectively 11.69%, 2.251%, 0.74% and 0.029% at 14th day and the content of macro nutrients on 28th day for C-organic, Nitrogen, Phosphorus and Potassium are respectively 11.28%, 2.366%, 0.77% and 0.041%.
