Abstract

Glucosamine is useful for overcoming joint disease or osteoarthritis. Glucosamine can be produced through synthesis involving carbon and amine. Carbon can come from plant derivatives that contain sugar, like coconut sap. While the amine branch can be derived from ammonium sulphate. This study aims to determine the effect of ammonium sulphate added as a precursor in the process of synthesizing glucosamine from coconut sap towards physiochemical characteristics of glucosamine. The research used a one-factor-randomized design with addition of six levels of ammonium sulphate, that are 1,5 M; 2M; 2,5 M; 3 M; 3,5 M and 4 M. The characterisation includes the glucosamine concentration, pH, solubility, colour, and loss on drying (LOD). The best treatment was selected by using the TOPSIS method. The results showed that the best treatment was the addition of a 3.5 M ammonium sulphate precursor compound which had a glucosamine content of 801.67 ppm; yield of 1.603%; pH 4.79; and LOD of 0.837%. The precursor concentration had significant effects on the yield of glucosamine synthesised from coconut sap. The higher of glucosamine content and the resulting yield indicate the efficiency of the treatment applied to the sample is higher.

Abstract

Nipa (Nypa fruticans Wurmb.) belongs to the Arecaceae family, covering 30% of over 4 million ha of mangrove forest in Indonesia. The most valuable part of nipa is the fruits for food, drink, handicrafts, and medicine, leaving empty fruit bunches as waste. The empty fruit bunch waste reaches 75% of the total weight of nipa fruit, producing approximately 6 Mt/ha or over 6 million Mt in a year. Nipa empty fruit bunches (EFB) are biomass containing 27.3% lignin, 36.1% cellulose, and 21.8% hemicellulose. Due to Indonesia’s increasing nipa fruit harvesting, managing and finding a suitable solution to overcome waste issues is essential. In the present review, nipa EFB’s physical and chemical properties were found suitable as a biomass energy source. Nipa’s EFB energy recovery was potentially generated from direct combustion, pyrolysis, and briquette making. The harvesting challenge and emission from direct combustion or pyrolysis process limit the nipa utilization. Education and technology dissemination is required for the coastal communities to assist in utilizing nipa.

Abstract

Art paper made of betel nut husk fibre and paper waste is one example of an innovative product. Therefore, an analysis of the technical and financial feasibility of this innovation needed to be conducted. This research aimed to determine the technical and financial feasibility of the production business of art paper from betel nut husk fibre and paper waste. The technical aspect will focus on the technology utilized, primary raw material and additional raw material, production capacity, and any workforce involved in the business. Meanwhile, the financial aspect will emphasize the calculation of the Main Production Cost (MPC), Break Even Point (BEP), Business Efficiency (R/C Ratio), Payback Period (PP), Net Present Value (NPV), and Internal Rate of Return (IRR). The calculation result of the feasibility analysis shows that Production Cost (HPP) is IDR 12,786.00, BEPunit is 9,271 paper sheet, BEP (IDR) is IDR 148,326,906.00, R/C Ratio is 1.56, PP will be for 2.2 years, NPV is IDR 2,078,713,958.00, and IRR is 68.36%. Based on this result, this business on betel nut husk fibre and paper-based waste art paper is considered worth running.

Abstract

This paper aimed to comprehensively review the potential valorization of oil palm empty fruit bunches (OPEFBs) into activated carbon and its potential application. Activated carbon is carbon processed through dual phases, including carbonization and activation. Firstly, this process converts biomass into carbon thermally with zero to little oxygen conditions. Next, the carbon needs to be activated to stimulate the formation of pores and reduce impurities. The activated carbon’s quality is influenced by the activation process, which can be done physically, chemically, or physiochemically. Activated carbon has an amorphous structure and abundant internal pore structure, thus increasing the surface area. In Indonesia, the quality of active carbon is regulated by Indonesian National Standards or SNI 06-370-1995.  The factors influencing the activation step include activator agent type,  activator agent concentration, activation ratio and time, etc. . Generally, activated carbon can be widely applied to various sectors, such as agriculture (i.e., slow-released fertilizer, fertilizer, etc.), waste treatment (i.e., adsorbent, activator in anaerobic digestion/AD, bioremediation, etc.), gas purification, ceramic membrane, etc. However, further in-depth investigation is required to determine potential scaling-up and commercialization.

Abstract

An analysis of consumer preferences to find out the characteristics of handicraft paper from betel nut fiber desired is necessary for this innovation. This study aimed to determine the attributes of handicraft paper that are most necessary for consumers. This study was conducted by using Conjoint method. Fifty respondents completed structured questionnaires in some cities in Indonesia. The attribute mix used in this study was physical and organoleptic. The physical attribute mix was tensile strength, grammage, thickness, and stiffness while the organoleptic was color, fiber appearance, and surface texture. There were 16 combinations of stimuli formed with simplification using orthogonal arrays. The result shows consumers like tensile strength of 20-<30 kN/m2, grammage of ≥500 g/m2, thickness of 1,6-3 mm, stiffness of ≥15 mN.m, dark brown color, the appearance of fiber was visible, and had rough surface texture. The results of the correlation analysis showed that there was a strong correlation between the results of preference stimuli and actual responses. The handicraft paper produced had the same characteristics as the consumer preference, except the tensile strength with thevalue ranged from 10-<20 kN/m2. The results also showed that fiber appearance had the highest relative importance value to be prioritized.
