Abstract

Indonesia faces dual challenges in the form of high dependence on coal and increased volumes of leaf and ranting organic waste. This study studied the development of biomass pellets from leaf litter and ranting as renewable energy (EBT) initiated by PT Building Solutions Indonesia (SBI) Cilacap together with Cilacap State Polytechnic. Analysis includes technical concepts, environmental impacts through a life cycle approach, as well as implementation potentials and challenges. Results show the use of biomass pellets can decrease net greenhouse gas and methane gas emissions from leaf burning and ranting by the community, as well as supporting the circular economy model. The main challenges include production energy consumption and particulate emission control. The concept is technically and ecologically feasible with optimization and policy support as a prerequisite for commercialization.

Abstract

The rotary dryer is a machine designed to simplify the cocopeat drying process. The current process still relies on sunlight; this drying process has the drawback of longer drying times and uncontrolled moisture content. The maximum moisture content of the cocopeat must be 15%. This research method is an experiment using several parameters: a drum speed of 6 rpm, heating temperatures of 600°C, 900°C, and 1300°C, with varying drying times of 120 and 150 minutes. The drying process at a temperature of 600 °C resulted in a decrease in humidity efficiency of up to 56.7% with a water content value of 23.8% in 150 minutes and a mass of 3.7 kg. Meanwhile, for drying at a temperature of 1300 °C, the best reduction in efficiency was obtained compared to the previous temperature, a decrease in water content of up to 84% with a water content value of 8.55 and a mass of 2.7 kg using a time of 150 minutes.

Abstract

Politeknik Negeri Cilacap sebagai Perguruan Tinggi Negeri tunggal di Kabupaten Cilacap menjadikannya Perguruan Tinggi pilihan favorit masyarakat Cilacap dengan jumlah mahasiswa pertahun yang terus bertambah sehingga dengan sendirinya menuntut ruang parkir yang cukup. Permintaan parkir yang melebihi kapasitas parkir yang tersedia dan terhambatnya manuver kendaraan menyebabkan tertundanya pengunjung yang akan parkir sehingga dapat memicu adanya parkir di bahu jalan.. Penelitian ini bertujuan untuk mengetahui kelayakan tempat parkir di Gedung Kuliah Bersama Politeknik Negeri Cilacap sehingga dapat menjadi bahan evaluasi dalam mengoptimalisasi ruang parkir yang ada sehingga menjadi lebih baik lagi. Metode penelitian yang digunakan yaitu survey pengamatan lapangan dan kuesioner. Berdasarkan hasil penelitian menunjukan bahwwa kapasitas parkir pada hari puncak tidak memenuhi syarat yang dtunjukan dengan jumlah kendaraan yang parkir per jamnya melebihi kapasitas parkir yang ada. Indeks parkir (IP) > 1 artinya kebutuhan parkir masih diatas daya tampung sehingga dapat dikatakan “kurang layak”. Analisa tingkat kepuasan pengguna terhadap kinerja parkir pada saat waktu sibuk dapat dikategorikan “cukup layak”.

Abstract

Penggunaan lahan yang berbeda pada daerah sekitar Sungai Code tentu akan berdampak pada masukan bahan organik yang masuk ke dalam aliran Sungai Code. Jumlah masukan bahan organik akan mempengaruhi kualitas dari air Sungai Code. Pemetaan kualitas air sungai Code dapat menggunakan bioindikator berupa larva Chironomidae. Penelitian dilakukan pada Bulan Oktober tahun 2022 pada lima stasiun penelitian yang menginterpretasikan daerah sebelum perkotaan, daerah perkotaan, dan setelah perkotaan. Sampel larva Chironomidae cuplik dengan menggunakan alat surber sampler 30x30 cm2 dan dilakukan analisis korelasi Pearson untuk melihat korelasi kemelimpahan larva Chironomidae dan faktor fisik dan kimia sungai Code.  Pada periode penelitian ditemukan dua genus larva Chironomidae yaitu Chironomus dan Cricotopus. Dari keseluruhan stasiun penelitian larva genus Chironomus memiliki populasi tertinggi yaitu 88 individu. Dan berdasarkan penggunaan lahan, stasiun ke IV (daerah perkotaan) memiliki kemelimpahan larva Chironomidae tertinggi yaitu 192,59 ind/m2. Hasil uji korelasi Pearson pada taraf kepercayaan 0,05 menunjukkan bahwa kemelimpahan larva Chironomidae memiliki korelasi positif dengan parameter lingkungan yaitu TDS dengan nilai kontribusi 86,77%.

Abstract

This study evaluates Biomass-Shell Composite Fuel (BSCF) from lignocellulosic and seashell waste via fermentation and densification. Results show pellet moisture (2.64–11.0%) meets ISO 17225-6:2021 standards. The highest heating value was 12.11 MJ/kg in the mixed variant, though it was below the 14.5 MJ/kg minimum. Bulk density (0.12–0.37 g/cm³) and length (33–50 mm) were also below ideal standards. Incorporating seashells caused high ash content (32.16–34.84%). Consequently, BSCF pellets are recommended as an Alternative Fuel and Raw Material (AFR) for the cement industry, where mineral residues can substitute for limestone in clinker production. Optimization requires increased compaction pressure and reduced particle size to improve product efficiency.

Abstract

Climate change and environmental degradation require the financial sector to play an active role in supporting sustainability. Islamic finance has significant potential due to its foundational values that align with the principles of sustainable development. Contemporary Islamic accounting practices remain largely focused on formal compliance and have not yet comprehensively integrated environmental aspects. This study aims to analyze the integration of Green Accounting with the principles of Maqashid Syariah and Islamic environmental ethics, and to develop a conceptual framework for Islamic Green Accounting. This research adopts a qualitative approach through a systematic literature review of 32 selected articles sourced from Google Scholar (2015-2025) with the keywords Green Accounting, Maqashid Syariah, Islamic Finance, and ESG. The analysis employs content analysis and concept mapping, grounded in the Maqashid Syariah framework. The findings indicate strong alignment between Green Accounting and Maqashid Syariah, particularly in protecting life, progeny, and wealth. This study proposes a conceptual framework of Islamic Green Accounting that positions Maqashid Syariah as the value foundation, Green Accounting as the technical instrument, and sustainability as the ultimate objective.
