“…Even though large amounts of biomass are produced from the abovementioned agricultural waste, only 10% of the same is used as an alternative raw material in biocomposite-based industries, fertilizers, animal feeds, chemical derivatives, etc. [3]. It is estimated that in the mills, 23% of oil palm empty fruit bunches (EFB) are produced per ton of fresh fruit bunches [4].…”

The recognition of nanocellulose has been prominent in recent years as prospect materials, yet the ineffectiveness of nanocellulose to disperse in an organic solvent has restricted its utilization, especially as a reinforcement in polymer nanocomposite. In this study, cellulose has been isolated and defibrillated as cellulose nanofibrils (CNF) from oil palm empty fruit bunch (EFB) fibers. Subsequently, to enhance its compatibility with UV-curable polyurethane (PU)-based resin, the surface hydrophilicity of CNF has been tailored with polyethylene glycol (PEG), as well as reduced graphene oxide (rGO). The dispersibility of reinforced modified CNF in UV-curable PU was examined through the transmittance interruption of resin, chemical, and mechanical properties of the composite printed using the stereolithographic technique. Evidently, the enhanced compatibility of modified CNF and UV-curable PU was shown to improve the tensile strength and hardness of the composites by 37% and 129%, respectively.

“…OPEFB potential becomes the most important consideration because of its abundant availability (Olisa and Kotingo, 2014). OPEFB utilization has not been handled optimally by most palm oil companies (Palamae et al 2017), causing them to have a negative impact on the surrounding environment (Hendra et al 2014). The use of OPEFB as the mushroom growing media has not been widely performed (Tabi et al 2008;Hidayati et al 2015;Kavitha et al 2013).…”

Determining factors in the development of sustainable oyster mushroom agribusiness is an important issue presently considering oyster mushrooms have good opportunities and potential. This research aims to identify prioritizing factors in the development of sustainable oyster mushroom agribusiness in Kubu Raya Regency West Kalimantan Province. This research uses the descriptive method. Respondents were 30 key informants from related agencies (Agriculture Office of Food Crops and Horticulture, agricultural extension workers, researchers in horticulture, oyster mushroom entrepreneurs, and oyster mushroom traders). The research was conducted from March to June 2018. Data were analyzed by the Analytical Hierarchy Process (AHP) analysis. The result indicates that supporting facilities aspect is the most important criterion to be considered. The main sub-criteria are oil palm empty fruit bunches (OPEFB) potential (ecology), return on investment (financial), perception and attitudes of the community in consuming oyster mushrooms (socio-culture), capital (institution), labor availability (human resources), adoption readiness (technology), and market (supporting facilities). The main subsub criterion is market demand.Abstrak: Penentuan faktor-faktor dalam pengembangan agribisnis jamur tiram berkelanjutan merupakan isu yang penting saat ini mengingat jamur tiram memiliki peluang dan potensi yang baik untuk dikembangkan. Penelitian ini bertujuan untuk mengidentifikasi dan memprioritaskan faktor-faktor dalam pengembangan usaha agribisnis jamur tiram berkelanjutan di Kabupaten Kubu Raya Provinsi Kalimantan Barat. Metode penelitian yaitu metode deskriptif. Responden yaitu key informan berjumlah 30 orang yaitu pihak instansi terkait (Dinas Pertanian Tanaman Pangan dan Hortikultura, penyuluh pertanian, peneliti bidang hortikultura, pengusaha jamur tiram, dan pedagang pengumpul jamur tiram). Penelitian dilakukan bulan Maret sampai Juni 2018. Analisis data menggunakan Analytical Hierarchy Process (AHP). Hasil mengindikasikan bahwa aspek sarana penunjang adalah kriteria utama yang paling penting untuk dipertimbangkan. Sub-kriteria utama yaitu potensi tandan kosong kelapa sawit (ekologi), tingkat pengembalian investasi (finansial), persepsi dan sikap masyarakat dalam mengkonsumsi jamur tiram (sosial budaya), kelembagaan permodalan (kelembagaan), ketersediaan tenaga kerja (sumber daya manusia), kesiapan adopsi teknologi (teknologi), pasar (sarana penunjang). Sub-sub kriteria utama yaitu permintaan pasar.Kata kunci: AHP, tandan kosong kelapa sawit, sarana penunjang, permintaan pasar

“…The cellulose content on rice husks is 25-35 % (w/w), the hemicellulose content is 18-21 % (w/w), while lignin and minerals contents are 26-31 % (w/w) and 15-17 % (w/w), respectively [39]. OPEFB contained 24-65 % (w/w) of cellulose, 21-34 % (w/w) of hemicellulose, and 14-31 % (w/w) of lignin [40]. The lignocellulosic compounds are the main constituent which potentially converted into usable energy products.…”

Biomass-based energy from agricultural wastes is a promising alternative energy source since its abundant supply and renewable. Biomass is converted into gas and liquid fuel through biochemical or thermochemical treatments. In this work, oil palm empty fruit bunches (OPEFB) and rice husk are pyrolyzed to produce gas and liquid fuel. The reactor temperature and feed mass are varied to obtain the best operating condition in a semi-batch pyrolysis reactor. The experimental results showed that the best operating temperature in pyrolysis process to produce bio-oils from OPEFB and rice husk was at 500 °C with 4.3 % (w/w) and 2.6 % (w/w) of bio-oil yields, respectively. The pyrolysis product distribution and their chemical composition are strongly affected by operating condition and the types of biomass. The GC-MS analysis results showed that the primary pyrolysis products components consist of hydrocarbons and oxygenated compounds such as carboxylic acids, phenols, ketones and aldehydes. Thermodynamic properties such as thermal conductivity of the biomass also influenced the product distribution of the biomass pyrolysis.
