Abstract

Large quantities of by-products from areca nut and coconut processing generated annually have significant potential as solid fuel feedstocks due to their high lignocellulosic content. Optimal utilization of these residues can increase their added value and reduce the environmental impacts associated with organic waste. This study aimed to explore the manufacturing process and characteristics of biobriquettes made from biomass waste in the form of areca nut husk, coconut husk, and coconut shell. These raw materials were processed through the stages of cleaning, drying, carbonation, refining, mixing with adhesives, molding, and drying. The use of adhesives such as tapioca flour, sago, or palm oil liquid waste affects the quality of biobriquettes, including their moisture content, ash content, calorific value, density, and combustion rate. The results of the study revealed that biomass-based biobriquettes have several advantages, such as being cost-effective, environmentally friendly, and producing a high calorific value. This study provides scientific and practical benefits to the processing of biomass waste into renewable energy with high economic value.  The utilization of this waste not only enhances renewable energy production but also reduces agricultural waste and environmental pollution.

Abstract

An experiment to test the growth and development of selected legumes, i.e. Peltophorum pterocarpus DC Heyne (soga), Cassia multijuga Rich. (kasia), Cassia surattensi Burm. f. (galenggang) and Caesalpinia pulcherrima Swartz (kembang merak),  on tin tailings was conducted at Tambang Terentang 25, Pangkal Pinang Production Site, Bangka Tin Miningfrom mid March 1989 to January 1990. The four legumes were selected for the facility in obtaining seed, their ability to improve soil fertility, and their ornamental value. The experiment on four legumes on tin tailing, compared to those grown on yellowish brown Podzol association and Bangka podzol, consisted of four parallel trial units based on the randomized block design with three replications. The tests results of 14 weeks of growth indicate the legumes tested, with the exception of Cassia surattensi Burm.f possess an adequate potential to be grown and developed on tin tailing for the improvement of visual quality, vertical and horizontal structure, and ecological function of the lanscape tailing on Bangka Island.

Abstract

Bleaching earth ialah bahan tambahan atau pemucat yang digunakan untuk memperoleh tingkat mutu warna standar pada CPO. Semakin banyak konsentrasi bleaching earth yang ditambahkan maka semakin besar kemampuan adsorpsi terhadap pigmen, sehingga warna minyak menjadi lebih terang. Namun setelah dilakukan pengamatan langsung di lapangan, terdapat perbedaan hasil warna yang menunjukkan tidak ada pengaruh terhadap penambahan bleaching earth terhadap warna RBD Palm Oil yang dihasilkan. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi bleaching earth terhadap warna produk RBD Palm Oil. Penelitian ini dilakukan dengan menggunakan alat pengukur warna Lovibond Tintometer, dengan mengamati 5 taraf konsentrasi yaitu 1,4, 1,5, 1,6, 1,7, dan 1,8 (%), terdapat 3 sampel dan dilakukan 3 kali percobaan pengujian warna. Penelitian mengaplikasikan metode analisis regresi linear sederhana yaitu koefisien determinasi (R²). Hasil perhitungan nilai regresi linear sederhana yaitu Y= 2,85-0,3X yang menunjukkan hubungan antara variabel X dan Y bersifat negatif atau berbanding terbalik dan hasil koefisien determinasi (R²) yaitu R²= 0,302 yang menunjukkan 30% konsentrasi bleaching earth mempengaruhi warna RBD Palm Oil, sedangkan sisanya (100% - 30% = 70%) dipengaruhi oleh faktor lain.

Abstract

The increasing accumulation of coconut and areca nut processing residues in Pengabuan District, Tanjung Jabung Barat Regency, Jambi Province, creates environmental concerns. Although coconut shells, coconut husks, and areca husks are abundant, integrated technical feasibility assessments for industrial-scale biobriquette production remain limited. This study aimed to conduct an integrated technical feasibility assessment to establish a biomass-based biobriquette manufacturing plant using locally available agricultural residues. A mixed-method approach employed field observations, interviews, and literature review. Technical feasibility was evaluated based on biomass availability, production process design, mass balance, industrial site selection using the Weighted Factor Method, and factory layout planning using Systematic Layout Planning (SLP). Results showed biomass availability was sufficient for industrial-scale production. The proposed plant can produce 792,000 kg of biobriquettes per year with a production yield of 36.87%. The biobriquettes complied with the Indonesian National Standard (SNI), Parit Pudin Village achieved the highest suitability score (4.25) and was selected as the optimal industrial site. The novelty of this study lies in the development of an integrated technical feasibility framework that combines biomass resource assessment, production system design, mass balance analysis, industrial site selection, and factory layout planning into a single decision-making model. These findings indicate that integrated technical planning enhances implementation readiness in the biomass industry. The framework provides practical guidance for industry stakeholders and policymakers to promote agricultural waste valorization and renewable energy development while supporting future techno-economic and sustainability assessments.
