Abstract

The effect of conventional convective drying (CCD) and convective solar drying (CSD) based on a solar collector and photovoltaic on the quality of dried red pepper was researched. The study was aimed to determine the effect of five drying system (CCD 50°C, CCD 60°C, CCD 70°C, CSD, and open sun drying) on the quality attributes of dried red pepper. The quality observed were rehydration ratio, ascorbic acid, capsaicin, non-enzymatic browning index, anthocyanin, and carotenoids. The results of the study confirmed that the drying system significantly affected the quality attributes of dried red pepper except for anthocyanin. The CSD had a satisfactory result, shown by some attributes (carotenoids, ascorbic acid, and ratio) which were not statistically different from the quality of dried red pepper gained from CCD 50°C.

Abstract

The higher of coconut crop production in Indonesia has positively correlated with the amount of coconut shell waste produced which is difficult to decompose by microorganisms. Therefore, the utilization of coconut shell waste into charcoal and liquid smoke has been carried out in recent years. During this time, the conventional process of coconut shell-liquid smoke (CS-LS) takes 3-5 days and produces grade C liquid smoke in low volume. Hence, this study aims to design CS-LS production machine based on cyclone-redistillation technology which which can increase the volume of liquid smoke produced. In this study, the method used was engineering includes structural and functional design also testing performance both apparatus and product. The performance of CS-LS production machine was analyzed by volume for each grades (grade A, B and C). The result showed that CS-LS production machine based on cyclone-redistillation has been production according to specifications, with the total dimension of machine was 132 cm length, 100 cm width and 145 cm height. The volume of grade A CS-LS production was 65 L, whereas the grade B and C volumes was 10 L and 25 L, respectively, with a shorter total production time than conventional methods in SMEs. Therefore, design of CS-LS production machine based on cyclone-redistillation technology has great potentially applied in SMEs for producing liquid smoke in Indonesia to increase productivity and quality of CS-LS.

Abstract

Bioplastics are environmentally friendly materials that serve as alternatives to synthetic plastics, capable of being decomposed by microorganisms. Starch, commonly sourced from tubers such as canna tubers, is one of the primary natural components used in bioplastic production. This study utilized a completely randomized factorial design with glycerol as a plasticizer and cellulose acetate from Oil Palm Empty Fruit Bunches (OPEFB) as a reinforcement agent. Glycerol was varied at concentrations of 1, 2, 3, 4, and 5 ml, while cellulose acetate OPEFB was varied at 1, 1.5, 2, 2.5, and 3 g. The resulting bioplastics underwent mechanical testing, including tensile strength, elongation, elasticity, water absorption, solubility, and biodegradability. The highest tensile strength (20.56 MPa) was observed with 2 ml glycerol and 1.5 g cellulose acetate OPEFB. The best elongation (33.33%) occurred with 4 ml glycerol and 1 g cellulose acetate OPEFB. Maximum elasticity (2.86 MPa) was achieved with 2 ml glycerol and 2.5 g cellulose acetate OPEFB. Optimal water absorption (12.54%) was recorded with 1 ml glycerol and 1 g cellulose acetate OPEFB, while the highest solubility (43.97%) was observed with 5 ml glycerol and 3 g cellulose acetate OPEFB. The greatest biodegradability (88.75%) was achieved with 5 ml glycerol and 1.5 g cellulose acetate OPEFB. These findings highlight the potential of starch-based bioplastics reinforced with cellulose acetate OPEFB to achieve desirable mechanical and environmental performance characteristics.
