Abstract

Energy is generally divided into two, the first is non-renewable energy for example oil, coal, and natural gas while the second is renewable energy such as water power, solar power, wind power, and biomass. Briquettes is one of the developments of biomass as an alternative fuel. The purpose of this study was to make and analyze the characteristics of coffee grounds briquettes using an adhesive from orange peel with torrefaction method. Torrefaction is a low temperature (200-300 oC) carbonization process without oxygen. Briquettes are made by percentage of coffee grounds and orange peel adhesive 70% : 30%, 60% : 40%, and 50% : 50%. Torrefaction process with a temperature of 200 oC within 60 minutes without any air or little air in the furnace with the addition of modified elbows. The results showed that the best composition was found in DK1 with a ratio of 70% coffee grounds with 30% orange peel adhesive, which has density 0.49 gr/cm3, water content 5.11%, volatile matter content 78.33%, bound carbon content 17.31%, 0.62% ash content, and 4656 cal/gr calorific value

Abstract

Tekno ekonomi erat kaitannya dengan pengambilan keputusan untuk menjalankan suatu bisnis. Penelitian ini bertujuan untuk menganalisis aspek teknis dan ekonomis produksi briket berbahan baku arang tempurung kelapa di PT XYZ. Pada penelitian ini, tekno ekonomi digunakan untuk menganalisis kelayakan bisnis briket yang meliputi analisis kualitas briket dan biaya proses pembuatan briket dalam kegiatan usaha PT XYZ. Data yang diperoleh dianalisa menggunakan analisis deskriptif. Pengujian kualitas briket yang dilakukan adalah kadar air, kadar abu, volatille matter, fixed carbon, nilai kalor dan laju pembakaran; Hasil analisis menunjukkan bahwa setiap tahunnya perusahan mampu memproduksi sebanyak 532.560 kg/tahun sedangkan dari sisi rendemen yaitu 71,43%, dengan nilai susut sebesar 28,57%. Berdasarkan perhitungan HPP dihasilkan harga sebesar Rp 20.000 per kilogramnya. Perusahan harus memproduksi briket arang tempurung kelapa sebanyak 135.890,8687 dan harus memperoleh omset sebesar Rp 2.165.306.215 untuk mencapai titik impas. Lama pengembalian modal didapatkan sebesar 1,53 yang berarti modal yang dikeluarkan oleh PT XYZ akan kembali dalam kurun waktu 1 tahun 6 bulan 11 hari. Hasil NPV bernilai positif dan nilai BCR sebesar 1,650 sehingga proyek layak dilaksanakan karena investasi yang dicapai mampu memberikan keuntungan sampai periode yang diperhitungkan. Kontribusi dari penelitian ini pada tambahan informasi yang didapatkan dan dapat bermanfaat bagi pihak perusahaan sebagai pertimbangan dalam pengambilan keputusan serta dalam penentuan harga jual yang tepat. Peningkatan promosi produk agar penjualan produk briket arang tempurung kelapa ini lebih banyak peminatnya sehingga penjualan meningkat dan menambah keuntungan perusahaan.

Abstract

Fertilizer is a vital component in supporting agricultural productivity; however, low soil fertility and farmers’ dependence on synthetic chemical fertilizers have long-term negative impacts on soil health, the environment, and overall productivity. Therefore, an environmentally friendly and sustainable fertilizer innovation is required. Polychar Plus Granule fertilizer was developed as an alternative based on biochar enriched with macro- and micronutrients, and formulated in granule form for more practical application. Biochar functions as a soil conditioner that improves cation exchange capacity (CEC), maintains soil moisture, and supports the growth of beneficial soil microorganisms. The addition of organic materials and minerals (N, P, and K) enables this fertilizer to not only improve soil structure but also supply plants with balanced nutrition. This community service activity was carried out through training, demonstration of fertilizer formulation, and field mentoring at the partner farm Tefa Rintisan Rumah Organik. The main objectives were to: (a) enhance sustainable soil fertility, (b) reduce dependency on chemical fertilizers, (c) provide appropriate technology based on local resources (activated charcoal, organic waste, rice husk ash, etc.), and (d) increase production economically. The expected outputs include publication in an ISBN-proceeding at the National Seminar on Research and Community Service (NaCosVi) Politeknik Negeri Jember 2025, activity videos uploaded to the P3M Politeknik Negeri Jember YouTube channel, coverage in the Radar Jember online media, and an article published in an accredited community service journal. It is expected that Polychar Plus fertilizer technology can be independently adopted by farmers as an alternative solution to support sustainable agricultural systems.
