Abstract

ANALISIS UNJUK KERJA HE TIPE PLAT REAKTOR KARTINI DENGAN METODE HILANG TEKANAN (PRESSURE DROP). Telah dilakukan analisis unjuk kerja HE tipe plat reactor Kartini menggunakan metode hilang tekanan (ΔP). Analisis dilaksanakan setelah perawatan HE dengan cara pelepasan plat-plat nya untuk dibersihkan, sesuai dengan prosedur perawatan. Berdasarkan data hilang tekanan pada sisi primer ΔP11 = 0,6 kg/cm2 dan hilang tekanan tekanan sisi sekunder ΔAP12 = 2,9 kg/cm2 Berdasarkan hasil analisis dapat disimpulkan bahwa setelah dioverhoul, dibersihkan dan diuji untuk operasi reaktor pada daya 100kW, HE telah mengalami kenaikan unjuk kerja yaitu ΔUf = 930,144 W/m2. K; Δɛ = 0,04; ΔCs = 0,426; ΔCf = 0,274; ΔNTU 0,025 dan ΔQact = 20,635.kW.

Abstract

ANALISIS STABILITAS SUHU TERAS REAKTOR TRIGA 2000 BANDUNG AKIBAT TRANSIEN REAKTIVITAS. Penelitian ini dilakukan untuk memperoleh gambaran tentang stabilitas dan respon transien suhu teras akibat perubahan reaktivitas selama operasi rutin. Diasumsikan reaktor sebagai suatu sistem linier tergumpal dengan neutron kasip satu grup, pengaruh fraksi hampa serta racun xenon terhadap reaktivitas diabaikan. Dan hasil evaluasi yang dilakukan dengan metode Nyquist, metode Root Locus dan diagram Bode diperoleh informasi bahwa, sistem selalu dalam keadaan stabil berapapun penguatanya dan mempunyai respontransien yang baik, karena perbandingan koefisien suhu negatif air terhadap bahan bakar adalah 1,54 lebih kecil dan batas atasnya, yaitu 14 x 106. Dengan menggunakan diagram Bode dapat ditunjukan pula sistem mempunyai kestabilan relatif dengan gainmargin 65 db dan phase margin 41° yang terjadi pada frekuensi-frekuensi jauh di atas frekuensi termal.

Abstract

This article investigates the distribution of zakat from agricultural products in Nagari Punggasan, West Sumatra. It employs a normative empirical method, analyzing legal provisions through a sociological and jurisprudential lens. Empirically, the study focuses on practices observed in Nagari Punggasan. The distribution of zakat from crops is calculated based on the capital utilized from the onset of cultivation until the harvest. Once the harvest is complete and the funds have been disbursed, the zakat obligation is considered fulfilled. This distribution process involves inviting all relevant community members, including Ninik Mamak, Labai, Imams, Khatibs, widows, and affluent individuals.However, this practice raises concerns regarding its alignment with Islamic teachings, particularly Surah At-Taubah, verse 60, which outlines the rightful recipients of zakat. According to the principles of Maqasid Shari'ah, the purpose of Shari'ah is to benefit humanity, ensuring both the spiritual and physical well-being of individuals and society at large. The objectives of Maqasid Shari'ah emphasize the importance of respecting the rights of the asnaf (eligible recipients) who are entitled to receive zakat.
