Abstract

Limited resource of fossil fuel inspires many research activities to search for alternative energy. This work offers alternative solution to address this problem through charcoal gasification. The goal of this research is to find the amount of syngas produced in the gasification is process. The alternative fuel was produced from the mixing rice husk and low quality coal due to their abundant resource in South Kalimantan. The mixture was then gasified at 500 °C. The highest syngas volume at 29.56 L was in the sample of SP 200 gr and BB 0 then followed at 25.7 L for ratio SP 180 gr : BB 20 gr. The lowest produced syngas 19.45 was produced from the sample with ratio SP 100 gr : BB 100 gr. This gasification process also resulted in side product, i.e. tar component which varies from 22.5 mL to 58.75 mL.

Abstract

In recent few years, many works have been dedicated to search for new source of renewable energy. In this study, new source of renewable energy is based in the briquette made from mixture of ironwood (Eusideroxylon zwageri) powder and gelam (Melaleuca leucadendron) wood powder. The mixture was carbonized at temperature of 500 oC ± 10 oC for 120 minutes. The size of the particles used was 50 mesh while the ratio between wood powder adhesives, i.e. starch powder, used in the study was 1:1. The composition variations between ironwood charcoal and gelam were 100% ironwood charcoal powder and 0% gelam, 70%: 30%, 50%: 50%, 30%: 70%, 0% ironwood: 100% gelam. The compaction pressure during briquette production was varied at 100 kg/cm2, 125 kg/cm2 and 150 kg/cm2.  The highest combustion temperature at 205 oC occurred in the specimen with composition of 30% ironwood powder and 70% gelam wood powder with compaction pressure of 100 kg/cm2. The longest burning duration 140 minutes (2 hours 20 minutes) occurred at composition of 50% ironwood powder and 50% gelam wood powder at compaction pressure of 150 kg/cm2. The fastest initial ignition time was 7 minutes and occurred for mixture with composition of 70% ironwood powder and 30% gelam wood powder at compaction pressure of 125 kg/cm2.

Abstract

In Kalimantan, gelam (Melaleuca cajuputi)  grows naturally in the swamp forest reaching 40 m with a diameter around 35 cm. Gelam wood is very resistant to acid soil in the swamp forest. Despite of it’s small diameter, gelam wood is very strong. This wood is usually used as the main house, as mold or mall support in casting concrete. Ulin (Eusideroxylon zwageri) is a typical plant of Kalimantan. In this study, the ignition duration, burning speed, and ash weight from briquette made from mixture of ulin and gelam sawdust was investigated. Size of sawdust used for briquette was varied for 40, 50, and 60 mesh while compaction pressure during briquette production was varied for 100, 125 and 150 kg/cm2. The study shows that the highest combustion temperature at 178 oC occurred for briquette with compaction pressure of 150 kg/cm2. Meanwhile, the lowest combustion temperature was obtained in briquette witch compaction pressure of 100 kg/cm2.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pengurangan kadar air terhadap kualitas pemipilan jagung menggunakan mesin pemipil tipe spiral rotary. Jagung hibrida Bima 9 diuji dengan empat perlakuan pengeringan yang berbeda, yaitu tanpa pengeringan (S0), dijemur selama 8 jam (S1), dioven selama 1 jam pada suhu 90°C (S2), dan dioven selama 2 jam pada suhu 90°C (S3). Sampel jagung dipipil menggunakan mesin pemipil tipe spiral rotary, dan hasil pemipilan dianalisis berdasarkan efisiensi mesin, kualitas pemipilan, dan kerusakan biji. Hasil penelitian menunjukkan bahwa pengurangan kadar air meningkatkan efisiensi mesin dan kualitas pemipilan, dengan kadar air 18.3% (S3) menghasilkan rata-rata efisiensi mesin tertinggi sebesar 85% dan pemipilan yang bersih, meskipun dengan sedikit kerusakan pada biji. Kadar air yang lebih tinggi, seperti pada S1 (24.4%), menghasilkan efisiensi mesin yang rendah dan banyak biji yang tertinggal pada tongkol. Penelitian ini menyarankan bahwa kadar air optimal untuk pemipilan jagung menggunakan mesin pemipil spiral rotary adalah sekitar 18–22%. Temuan ini memberikan kontribusi dalam meningkatkan efisiensi pemipilan jagung di industri pengolahan pakan ternak.

Abstract

Bank Sampah Sekumpul merupakan inovasi dalam pengelolaan sampah yang menggabungkan prinsip lingkungan dan ekonomi. Dari hasil diskusi dengan mitra, dalam perkembangannya Bank Sampah Sekumpul menemui beberapa permasalahan, salah satunya yaitu sulitnya mengatasi sampah plastik seperti kresek dan plastik mika sisa makanan. Oleh karena itu, diperlukan suatu kegiatan pelatihan untuk mitra agar dapat mengendalikan sampah plastik dengan aman dan tidak mencemari lingkungan. Berdasarkan hal tersebut, tim PkM memberi solusi berupa alat pembakaran sampah plastik dengan metode wet scrubber. Tujuan dari kegiatan PKM ini yaitu untuk meningkatkan pengetahuan dan keterampilan mitra dalam mengatasi limbah plastik dengan menggunakan alat pembakaran. Alat ini mempunyai tabung pembakaran dengan kapasitas 15 kg, dan dapat membakar sampah sebanyak 1 kg dalam waktu 2 menit. Metode yang digunakan berupa tutorial penggunaan alat pembakaran sampah dengan metode wet scrubber. Hasil dari kegiatan ini yaitu mitra mendapatkan pemahaman tentang pengendalian limbah plastik dengan cara meminimalisir polusi, penggunaan alat pembakaran sampah dengan aman, serta teknis perawatan alat pembakaran sampah agar tetap dapat berfungsi dengan baik. Untuk keberlanjutan program, kegiatan pengabdian kepada masyarakat ini diharapkan terus berlanjut dengan cakupan yang lebih luas agar dapat berkontribusi terhadap kebersihan lingkungan.
