Abstract

Penelitian ini bertujuan untuk mengetahui sifat fisis papan partikel yang terbuat dari bahan serbuk kayu dan limbah bulu ayam. Variasi komposisi bulu ayam, serbuk kayu dan perekat resin epoxy berturut-turut yaitu : sampel A(5%:50%:45%), B(10%:45%:45%), dan C(15%:40%:45%). Parameter uji fisis meliputi kerapatan, kadar air dan pengembangan tebal. Hasil uji fisis papan partikel berbahan bulu ayam, serbuk kayu dan perekat resin epoxy yang optimal terdapat pada sampel C dengan nilai kerapatan 0,60 g/cm3, kadar air 7,85%, dan pengembangan tebal 10,4%. Pada penelitian ini sampel telah sesuai SNI 03-2105-2006 dan papan partikel ini masuk pada penggunaan umum (struktural).

Abstract

Dilakukan penelitian pembuatan briket arang menggunakan bahan utama kulit salak dan divariasiasikan antara kulit salak dan perekat tepung tapioka yang di tambah getah karet  kulit salak yakni : sampel A (70%:30%), B (60%:40%), dan C (50%:50%), formula perekat dan air  (1:3), dan dikeringkan hingga 7 hari. Pengujian pada penelitian yakni : uji fisika dan kimia mencakup  kadar air, nilai kalor, kadar abu, kadar zat terbang juga kadar karbon. Didapatkan briket arang kulit salah yang bagus dari hasil dari pengujian fisika dan kimia yakni di sampel A (70%:30%) dengan persentaase air 4,13%, persentase kalor 4.707 Cal/g, persentase abu 6,42%, persentase zat terbang 6,27% serta persentase karbon 76,42%. Sampel briket arang sudah setara di SNI No. 01-6235-2000 jadi, briket arang bisa diaplikasikan di ruang lingkup rumah tangga.

Abstract

Minyak goreng merupakan kebutuhan pokok yang diperlukan untuk menggoreng makanan. Dikatakan baik suatu minyak goreng bila minyak goreng berwarna bening kekuningan dan terbuat dari tumbuhan serta hewani yang diolah secara buatan. Penelitian ini bertujuan untuk memurnikan minyak goreng jelantah menggunakan karbon aktif tempurung kelapa dengan aktivasi fisika sebagai adsorben. Hasil penelitian ini memperoleh bau dan rasa normal, warna, normal, nilai kadar air: 0,06% dan nilai ALB: 0,15% yang nilainya tidak melebihi dari standar maksimum yang dipersyaratkan SNI 7709:2019

Abstract

Tofu liquid waste treatment is very important because of its high organic content and can cause environmental pollution. This research uses electrocoagulation method with cylindrical aluminum electrodes to lower Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) levels. The variation of the treatment time used is 45, 60, and 75 minutes with a voltage of 12 volts and a distance between the electrodes of 2 cm. The test results showed that the BOD concentration decreased from 816 mg/L to 57–104 mg/L (efficiency 87–93%), while COD decreased from 2696 mg/L to 78–118 mg/L (efficiency 95–97%). In addition, the pH increased from 3.44 to 6.03–6.99 so that it is close to neutral condition. All final results meet the quality standards of liquid waste according to the Regulation of the Minister of Environment and Forestry No. 5 Year 2014, as well as aluminum content according to drinking water quality standards according to Permenkes No. 492/MENKES/PER/IV/2010. Thus, electrocoagulation using cylindrical electrodes is proven to be effective, environmentally friendly, and potentially applied to small to medium-scale tofu waste treatment.

Abstract

Research has been conducted aimed at testing the results of tofu liquid waste samples on the Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) parameters before and after the electrocoagulation process using Al, Cu, and Zn electrodes. This study used tofu liquid waste from Jl. Pasar V Helvetia. The BOD test results before electrocoagulation were 816 mg/L. The BOD test results after electrocoagulation with Al electrodes were 112 mg/L, Cu electrodes were 55 mg/L, and Zn electrodes were 115.2 mg/L. The COD level test results before electrocoagulation were 2696 mg/L. The COD level test results after electrocoagulation with Al electrodes were 95 mg/L, Cu electrodes were 62 mg/L, and Zn electrodes were 105 mg/L. From the electrode variations, the best results were obtained for testing the BOD and COD levels of tofu liquid waste on the Cu electrode.
