Abstract

Biodegradable plastic is a type of plastic made from renewable materials and can be produced using materials containing starch, such as in avocado seeds. However, starch-based biodegradable plastic has the disadvantage of low mechanical properties, such as tensile strength and elongation; therefore, it is necessary to add reinforcement, such as cellulose. One potential source of cellulose with a relatively high content is areca nut skin. This study aims to obtain the appropriate concentration of areca nut skin cellulose for the characteristics of biodegradable avocado seed starch plastic. A completely randomized design (CRD) with five treatments and three replications was used in the experimental procedure of the investigation. The treatments in this study were the addition of cellulose S1 (3 g), S2 (4 g), S3 (5 g), S4 (6 g), and S5 (7 g), and the measured characteristics were water absorption, water vapor transfer rate, tensile strength, elongation, and biodegradability. The data obtained were analyzed statistically using analysis of variance (ANOVA). The results showed that the addition of areca nut cellulose significantly affected the water absorption capacity, water vapor transfer rate, tensile strength, elongation, and biodegradability of biodegradable plastics. The selected biodegradable plastic was treatment S1 (3 g), which showed a water absorption capacity of 58.80%, a water vapor transfer rate of 17.03 g/m²/hour, a tensile strength of 30.73 MPa, an elongation of 9.31%, and biodegradability of 44.24%.

The study was conducted experimentally using a Complete Randomized Design (CRD) with five treatments and three replications to get 15 experimental units. The treatments in this study were the ratio of palm oil leaves charcoal and rubber seed shells charcoal namely: DC1 (50:50), DC2 (40:60), DC3 (30:70), DC4 (20:80) and DC5 (10:90). Data were statistically analyzed using Analysis of Variance (ANOVA) follow add Duncan’s Multiple Range Test (DMRT) at 5% level. The parameters observed were density, compressive strength, moisture content, vapor content, ash content, bound carbon content, and heating value. The results of palm oil charcoal leaves and rubber shells charcoal with tapioca adhesive have a significant effect on density, compressive strength, water content, vapor content, ash content, bound carbon content and heating value. Based on the analysis results, the best treatment in this study was DC5 (10:90) with a water content of 4.85%, density of 0.56 g/cm3, compressive strength of 0.48 kg/cm2, ash content of 3.43%, evaporating content of 11.68%, bound carbon content of 80.12%, and heating value of 7,504.59 cal/g.

Abstract

The purpose of this study was to obtain a comparison of dried shrimp nuggets and young jackfruit to quality (moisture content, ash content, protein content, fat content, and crude fiber content) and sensory nugget of shrimp and young jackfruit. The research method used a completely randomized design with four treatments and four replications. The treatments consisted of UN1 dried shrimp: young jackfruit (70:30), UN2 dried shrimp:young jackfruit (60:40), UN3 dried shrimp:young jackfruit (50:50), and UN4 dried shrimp: young jackfruit (40:60). The data obtained were analyzed statistically using the analysis of variance and continued with the Duncan’s Multiple range test (DMRT) at the 5% level. The results of the analysis showed that the combination of dried shrimp and young jackfruit had a significant effect on moisture, ash, fat, protein and crude fiber content, as well as descriptive and hedonic sensory assessments such as color, aroma, taste and texture. The best treatment was UN1 dried shrimp: young jackfruit (70:30) with the moisture content was 58.68%, ash content was 4.44%, fat content was 4.14%, protein content was 11.65%, and crude fiber content was 0.99%. Descriptive sensory assessment was brown in color, very flavorful of dried shrimp, very dried shrimp taste, and chewy texture and hedonic judgments are favored by the panelists.

Abstract

Oil palm trunks and coconut shells are biomass waste that can be used to make charcoal briquettes as an alternative energy source since they contain lignin and cellulose. The goal of this study was to find the optimum briquette character from a combination of oil palm trunk charcoal and coconut shell charcoal. This study employed a completely randomized design (CRD) with five treatments and three replications. In this investigation, the ratios of oil palm trunk to coconut shell charcoal were 90:10, 80:20, 70:30, 60:40, and 50:50. The data was statistically examined using analysis of variance (ANOVA) and Duncan’s New Multiple Range Test (DNMRT) at the 5% level. The study revealed that the ratio of oil palm trunk and coconut shell charcoal had an effect on specific gravity, moisture content, fixed carbon content, ash content, and calorific value. Briquettes (50:50) with a density of 0.77 g/cm3, a water content of 4.07%, a volatile content of 14.52%, an ash content of 6.25%, a carbon content of 75.14%, and a calorific value of 7,998.07 cal/g were the best treatment.

Abstract

This study aims to obtain selected characteristics of activated charcoal made from Nypa fruitcans shell with the help of phosphoric acid as an activator. This study was conducted using a completely randomized design (CRD) with four treatments and four replications. The treatments in this study used some concentration of phosphoric acid namely; H3PO4 7.5%, H3PO410%, H3PO4 12.5%, and H3PO4 15%. Parameters observe were the yield, moisture, ash, volatile matter and pure carbon contents as well as iodine absorption. The data obtained were analyzed statistically using statistical software IBM SPSS version 23 with an analysis of variance (ANOVA) test, if F count ≥ F table and continued with Duncan’s multiple range test (DMRT) at level 5%. The results showed that increasing the concentration of phosphoric acid used significantly affected all parameters on the activated charcoal. Activated charcoal with the best treatment was found in the N4 treatment with a yield 77.78%, moisture content 3.80%, ash content 6.86%, volatile matter content 7.48%, pure carbon content 81.86% and absorption of iodine of 869.27 mg/g.

Abstract

Essential oil from sweet orange peel can be obtained through a distillation process. Steam distillation is one of the methods commonly used to extract essential oils. This study aims to find the best distillation time for the physicochemical properties of essential oil from sweet orange peel. The study was conducted experimentally using a completely randomised design (CRD) method with 5 treatments and 3 replications to obtain 15 experimental units. The treatments in this study were P1 (2 hours), P2 (3 hours), P3 (4 hours), P4 (5 hours), and P5 (6 hours). The results of the study were analysed statistically using analysis of variance (ANOVA). The DMRT test was carried out at the 5% level if the F count was greater than the F table. Yield, refractive index, specific gravity, colour, and solubility in alcohol were the parameters analysed in this study. The results showed that distillation time affected the results analysed. P5 was the best treatment in this study, with a distillation time of 6 hours, producing a yield of sweet orange peel essential oil of 0.64%. This treatment has a refractive index of 1.4745, a specific gravity of 0.8119 g/ml, a colour L (brightness) of 31.48, a* (redness) of -0.2800, b* (yellowness) of 2.82, and a solubility in clear alcohol of 1:1.
