Abstract

The purpose of this research was to determine the effect of ethanol vapor and to find the best treatment concentration to maintain quality and extend the shelf life of cauliflower. The research used a completely randomized design (CRD) with five levels of ethanol concentration: 0%, 5%, 10%, 15%, and 20%. Cauliflower florets without ethanol vapor treatment were used as the control and stored at room temperature. The parameters measured were respiration rate, weight loss, color, vitamin C content, total dissolved solids, organoleptic properties (including color, smell, and freshness), and intensity of damage. The results showed that the 10% ethanol concentration was the best treatment, as it reduced respiration rate and weight loss, maintained color, suppressed the decrease in vitamin C content, achieved the best organoleptic scores for color, smell, and freshness, and reduced the intensity of damage in cauliflower.

Abstract

Biogas technology is an appropriate technology for treating livestock manure anaerobically by utilizingm ethanogenic bacteria to produce methane gas (CH4). Biogas uses renewable and flammable livestock manure raw materials with a clean methane (CH4) gas content and no black smoke. This study aims to obtain biogas production with the same length of fermentation time to obtain a comparison of batch and continuous biogas biodigester production in livestock manure biogas installations. The research began with a biodigester design using Microsoft paint and making a biodigester tool. The ratio of the combination of faeces and water is 1:1. The research was conducted in two trials, namely: a single batch biodigester containing 228 kg and a continuous batch of 228 kg with the addition of a mixture of raw materials once in three days of 18 kg. Both trials were observed every day using a U manometer to analyze batch and continuous biodigester biogas production. Based on the analysis of the specifications of the biodigester used, the capacity of the reactor tube is 0.254 m3, the raw material content capacity is 0.19 m3, the volume of the biogas chamber is 0.06 m3. The batch biodigester has a maximum pressure on day 25 of 104060.7 Pa with a production volume of biogas of 0.0616199 m3. The continuous system biodigester has a maximum pressure on day 25 of 105330.9 Pa with a production volume of biogas of 0.0623721 m3. Based on the trials, it was concluded that continuous biogas production produces higher pressure and volume of biogas than batches. The production of biogas once filled has the potential to produce more optimal biogas in a batch biodigester, while continuous biogas production will result in continued biogas production every day

Abstract

The physical characteristics of bioplastic packaging can be affected by the type and concentration of filler. This research was conducted to obtain bioplastic packaging films that met the Indonesian National Standard (SNI). The experimental design used was a randomized block design (RBD) with the first factor being the type of filler (J) with 2 levels: ZnO and cellulose. The second factor is the concentration of filler (K) with 3 levels, namely 0.5; 0.7; 0.9g. Each treatment was repeated three times, so the re were a total of 18 experimental units. The data will be analyzed using variance. If it turns out that the treatment has a significant effect on the parameters being observed, then the next step is to perform Duncan's test. The results indicated that the different types and concentrations of filler in the manufacture of bioplastic packaging had an effect on the values of tensile strength, elongation, elasticity, water absorption but had no effect on the rate of bioplastic biodegradation. Treatment with cellulose filler concentration of 0.5 g was the treatment that produced bioplastic packaging with the best characteristics, namely tensile strength of 14.31 MPa, elongation of 24.76%, elasticity of 53.72 MPa, water absorption of 0.71% and long biodegradati on time 7.5 days.
