Abstract

Penelitian ini bertujuan untuk mengevaluasi sistem manajemen laboratorium pendidikan PTKIN khususnya laboratorium Fisika UIN IB Padang, dengan metode deskrtiptif dan verifikatif dengan pendekatan kualitatif. Evaluasi mencangkup Pelayanan, K3 di laboratorium, Pengendalian pekerjaan pengujian dan/atau kalibrasi yang tidak sesuai, Persyaratan Teknis laboratorium, Kondisi akomodasi dan lingkungan, Peralatan dan Bahan, Sistem Pengelolaan sampel, Penanganan barang yang diuji dan dikalibrasi, Jaminan mutu hasil pengujian dan kalibrasi. Berdasarkan hasil evaluasi didapatkan bahwa tingkat kepuasan rata-rata pengunjung laboratorium Fisika UIN Imam Bonjol Padang berada pada range 3.75-4.75 berdasarkan interval 1.00-5.00. hal ini menunjukkan sistem tatakelola laboratorium jika dikategorikan cukup, baik dan unggul maka berada pada kategori baik ditinjau dari sumber daya (pelayanan, K3 dan peralatan).

Abstract

This study aimed to determine the effect of pyrolysis methods on the biochar yield from oil palm empty fruit bunches (EFB) using variations in material form and combustion systems. The research was conducted from March to May 2025 in Sorek Satu, Pelalawan Regency, Riau Province, and in the Soil Science Laboratory, Faculty of Agriculture, Riau University. The study consisted of several treatments: (1) whole EFB – external semi-vacuum combustion, (2) shredded EFB – external semi-vacuum combustion, (3) whole EFB – total internal vacuum combustion, and (4) shredded EFB – total internal vacuum combustion. Collected data from the study were analyzed using descriptive statistics. The results showed that external semivacuum pyrolysis produced a higher biochar yield compared to total internal vacuum pyrolysis, with the highest yield from whole EFB at 45.6% and shredded EFB at 32.8%. The total internal vacuum system failed to produce biochar and only resulted in dry material without undergoing carbonization. The chemical characteristics from the external semi-vacuum combustion system indicated that biochar from whole EFB had higher contents of carbon, potassium, magnesium, boron, and pH, while biochar from shredded EFB tended to have higher contents of nitrogen, calcium, and iron.
