Abstract

: The characteristics of dried candlenut are largely determined by temperature variations during drying. The purpose of this study was to determine the effect of variations in drying temperature on the fat content, protein content, and weight loss of candlenut (Aleurites moluccanus) seeds. Drying was carried out using an oven with three temperature variations, namely 40°C, 55°C, and 70°C. The parameters analyzed in this study included weight loss, water content, fat content, and protein content as indicators of quality and drying efficiency. The experimental design in this study used a Completely Randomized Design (CRD). The results showed that increasing the drying temperature significantly affected the fat content and weight loss. A temperature of 70°C produced the highest fat content of 67.64%, while a temperature of 40°C showed the lowest content of 60.96%. In addition, the higher the drying temperature, the greater the level of weight loss that occurs due to faster and more effective water evaporation. Protein content also experienced changes, although not significant, but tended to be stable at medium to high drying temperatures. Based on these results, it can be concluded that a drying temperature of 70°C is the optimal temperature for increasing the fat content and drying efficiency of candlenuts without significantly reducing the protein content.

Abstract

Coconut is a highly promising crop due to the wide variety of products that can be derived from it. One important form of coconut utilization is its processing into Virgin Coconut Oil (VCO). VCO can be produced through a fermentation method using yeast. This study aimed to evaluate the effect of different percentages of traditional ragi tape (Saccharomyces cerevisiae) on the physical and chemical quality of VCO. The experiment was conducted using a Completely Randomized Design with a single factor consisting of four treatments: 0%, 5%, 10%, and 15% ragi tape starter, each with three replications. Physical quality parameters included aroma, taste, and color, while chemical quality parameters comprised moisture content, free fatty acid (FFA) content, and peroxide value. The results showed that the percentage of ragi tape had no significant effect on the physical quality of VCO but significantly affected yield and chemical quality. The highest yield (23.3%) was obtained at the 15% treatment; however, the moisture content at 10% and 15% did not meet the SNI 7381:2022 standard. FFA levels in all treatments complied with the standard, whereas peroxide values in all treatments exceeded the SNI limit. Considering the balance between yield and chemical quality, the 5% ragi tape treatment was determined to be the best.

Abstract

Edible film is a thin layer that functions as a coating for food products, made from natural and consumable materials. One of the materials used in this study is cassava peel starch, which is suspended with glycerol and agar as plasticizers. This study aims to determine the characteristics of Edible film made from cassava peel starch and agar with the addition of different glycerol concentrations. The research was conducted using an experimental method and designed with a Completely Randomized Design (CRD), with glycerol treatments of 1,5 ml (P1), 2 ml (P2), and 2,5 ml (P3). The results showed that variations in glycerol concentration affected the biodegradation rate but did not significantly influence thickness, solubility, and absorption capacity of the Edible film. The best absorption capacity was observed at 1,5 ml of glycerol, while the best results for thickness, solubility, and biodegradability were found at 2.5 ml of glycerol. The use of 2,5 ml of glycerol is recommended as the optimal treatment in terms of both physical and microbiological properties, with the following characteristics: thickness of 0,19 mm, solubility of 40,8%, film absorption capacity of 29,7%, and film biodegradability of 79,3%, with a degradation rate of 10,9 mg/day.

Abstract

Chili pepper (Capsicum frutescens L.) is a high-value agricultural commodity rich in vitamin C and antioxidant compounds. However, drying processes may potentially reduce its physical and chemical quality. This study presents novelty by investigating the effect of low-temperature drying using a dehydrator at 45°C, 50°C, and 55°C for 10 hours on changes in the physical and chemical properties of chili pepper, aiming to determine optimal drying conditions to maintain product quality and functional value. The parameters analyzed included weight loss, moisture content, vitamin C content, and beta-carotene content. The experiment was conducted using a Completely Randomized Design (CRD) with a single factor and three replications. The results showed that drying temperature had no significant effect on the physical and chemical characteristics of chili pepper. Drying at 55°C resulted in the highest weight loss (78.70%) and the lowest moisture content (15.9%). The highest vitamin C content was obtained at 45°C (76.58 mg/100  g), while the highest beta-carotene content was also recorded at 45°C (78.69 mg/100  g). Appropriate selection of dehydrator temperature can help maintain quality and extend the shelf life of dried chili pepper.

Abstract

Chili Peppers(Capsicum frutescens) is a local chili variety typical of Sumbawa that has a high level of spiciness and nutrient content such as vitamin C and antioxidants. However, the short shelf life is an obstacle in its utilization, so this study aims to determine the effect of temperature variations in drying using an oven on the physical characteristics (weight loss) and chemistry (moisture content, vitamin C, and antioxidant activity) of forest cayenne pepper. The method used was a one-factor Complete Random Design (RAL), namely drying temperatures (50°C, 60°C, and 70°C), each with three replicates. The results showed that weight loss increased with temperature increase, highest at 60°C, but not statistically significant (p > 0.05). Moisture content decreased in all treatments, but the difference between temperatures was not significant (p > 0.05). The vitamin C content is significantly reduced at high temperatures (p < 0.05), with a temperature of 50°C being able to maintain vitamin C best. In contrast, antioxidant activity increased as the temperature increased, and the temperature of 70°C resulted in the highest DPPH inhibition value significantly (p < 0.05). This study concludes that drying temperature affects physical and chemical parameters differently, so the selection of drying temperature should be adjusted to the purpose of processing, whether to maintain vitamin C or increase antioxidant activity.

Abstract

One of the materials that can be used to make activated charcoal is bidara wood. Bidara wood has a high carbon content and a good pore structure. In addition, bidara wood also contains several minerals such as calcium, potassium, and magnesium in small amounts. The content of these compounds and elements makes bidara wood very suitable to be used as a raw material for activated charcoal. One of the activation materials is an H3PO4 solution. In the activation process, bidara wood activated charcoal can improve its quality properties, such as surface area, pore volume, and adsorption capacity. Therefore, the aim of this research is to determine the effect of heating temperature variations on the quality properties of bidara wood activated charcoal using chemical activation with an H3PO4 solution. The experimental design used in this study is a Completely Randomized Design with one factor, which is the activation temperature (500, 600, and 700˚C). The results of the study showed that the use of H3PO4 solution at a temperature variation of 700˚C resulted in better properties for moisture content (5.41%), ash content (43.29%), and iodine adsorption capacity (4,737 mg/g) compared to the temperature variations of 500˚C and 600˚C.

Abstract

Natural resources in Indonesia are very abundant, but there are still some that are not utilised properly so that they only become waste polluting the environment, one of which is acid wood. This waste can be innovated into briquettes. This study aims to identify the characteristics of briquettes from tamarind wood and coconut shells with starch adhesive, including moisture content, ash, volatile substances, bound carbon, and calorific value. This study uses a complete randomised design (CRD) as a tool to analyse significant data at the 0.05% level. Each concentration involves a variation of composition between tamarind wood charcoal and coconut shell charcoal, with additional starch adhesive in the ratio of 90%:10%, 45%:45%:10%, and 50%:40%:10%. Each sample will then be analysed for moisture content, ash content, volatile matter content, bound carbon content, and calorific value.  The results showed that the composition of the material mixture greatly affected the characteristics of the briquettes. The lowest average value of moisture content is at concentration P1 with a value of 1.69%, the lowest value in ash content is at concentration P1 with a value of 5.06%, the lowest volatile substance content is at concentration P1 with a value of 13.34%, the highest bound carbon is at concentration P3 with a value of 29.21% and the highest calorific value is at concentration P3 with a value of 6690 cal/gram. The characteristics that meet the SNI NO. 01/6235/2000 standards are only moisture content and calorific value, with the specified standards for moisture content <8% and calorific value >5,000. So from all five testing parameters of moisture content, ash content, volatile substance content, bound carbon content and calorific value, the best treatment was treatment P1 with 90% KA concentration: 10% adhesive.

Abstract

Natural resources in Indonesia are abundant, but some are not utilized properly, resulting in environmental pollution waste, such as kapok fruit husk and jatropha fruit. This waste can be innovatively processed into briquettes. This study aims to analyze the characteristics of briquettes made from kapok fruit husk and jatropha fruit using starch adhesive. An experimental method was used with variations in raw material composition: P1=(KK 45:BJ 45:PR 10), P2=(KK 60:BJ 30:PR 10), and P3=(KK 90:PR 10). The research design applied a Completely Randomized Design (CRD) to analyze significant data at a 0.05% level. The results showed that the lowest average moisture content was at P2 with a value of 1.69%, the lowest ash content was at P2 with a value of 9.10%, the lowest volatile matter content was at P3 with a value of 84.46%, the highest fixed carbon content was at P2 with a value of 4.80%, and the highest calorific value was at P3 with a value of 9,478%. The characteristics that meet the Indonesian National Standard (SNI No.1683-2021) are only moisture content and calorific value, with the standard requiring moisture content <8-10% and calorific value >6,000. These results indicate that briquettes can serve as an environmentally friendly alternative fuel with potential for further development.
