Abstract

Nowadays the use of plastics has become an important material so that the demand for home products as well as in industrial production is increasing. The activity of using plastics is increasing, causing complex environmental problems because it’s non-biodegradable. One of the biodegradable plastics is an edible film, which is a thin layer as a food packaging or coating which can be consumed together with the packaged product. In this research, the edible film was made using a synthesis method with raw materials such as crab shell chitosan, banana peel starch, and glycerol. Chitosan effects film reinforcement, starch functions as a film matrix former and glycerol also functions to increase the flexibility of the film. Through this research, it is hoped that the ratio of raw materials for the edible film including starch, chitosan, and glycerol can affect the characteristics of edible film such as tensile strength, percent elongation, percent of the solubility value in water.

Abstract

Ketapang tree (Terminalia Catappa Linn) is a wild plant that trees is not including trees cultivated. Ketapang tree (Terminalia Catappa Linn) spread to almost all regions in Southeast Asia, including in Indonesia except Sumatra and Kalimantan are somewhat rare in nature. Study of Extraction Tannins from Ketapang leaves (Terminalia Catappa Linn) is done to find a solvent extraction and concentration on the extraction of tannins from leaves ketapang (Terminalia Catappa Linn) using ethanol solvent. The extraction process is done in a laboratory-scale batch and by the principles of solid-liquid extraction in a three-neck flask stirred for the specified time, namely 30, 60, 90, 120, 150 (minutes) with the concentration of solvent (ethanol) 60%, 70%, 80%, 85%, 90% as variable variables. While the weight of the sample remains variable 10 grams, ± 200 mesh particle size, extraction temperature 85 ? C, stirring speed 200 rpm, ethanol solvent type, settling time ± 30 minutes, the solvent volume 250 ml, distilled water adjuvant. The best condition of the tannin extraction using 85% ethanol for 120 minutes obtained 98.97% yield tannin concentration.

Abstract

Variation of land use can affect the quality of groundwater and increase the potential for groundwater contamination. Physical environmental conditions that have a low sensitivity to contamination of groundwater, but the use of land which could potentially generate pollutants, such as industrial areas, residential, the agricultural activity can increase the risk level of contamination in the groundwater in the area. The purpose of this study is to develop a groundwater risk to contamination map in the shallow aquifer and to determine priority areas of groundwater quality monitoring in Salatiga Groundwater Basin. Groundwater risk to contamination map was prepared on aspects of land use and the degree of vulnerability of groundwater to contamination using DRASTIC methods and spatially was prepared by using Geographic Information System. Results of the assessment of risk levels obtained worth the risk index 93-204. The risk index values are grouped into five (5) classes of risk: low, low to medium, medium, medium-high, and high. The output of this research can be input for local governments in understanding the possible spread of groundwater contamination as well as choosing the right strategy for the conservation of groundwater resources in the Groundwater Basin of Salatiga.

Abstract

This community service activities aim to: 1) increase the ability of me3mbers to make solid soap and liquid soap; 2) increase partner knowledge of solid soap and liquid soap processing that can provide economic benefit; 3) increase partner understanding of financial analysis of the business. This community service implementation method is an empowerment model for partners, farmer women grup namely “Anggrek” in Cangkarman village, Bangkalan. The implementation methods used the following steps: 1) Discussion; 2) Training ; 3) Mentoring and Evaluation. The methods of community service are training, mentoring, and practice of making solid soap and liquid soap according to the basic formulation, marketing management, packaging, and labeling. The results obtained from this activity include: 1) partners can process coconut oil into solid soap and liquid soap 2) Partners have skill in the process of producing solid soap and liquid soap; 3) Partners understand the benefits of making solid soap and liquid soap for increasing family income.

Abstract

The aims of this brief overview are providing the knowledge about the physical and chemical properties of perovskite oxides in various synthesis method and the correlation of its performance for separating oxygen from air. Perovskite oxide showed excellent conductor of ion and electron, simultaneously through oxygen lattice in the crystal structure. In the present review, we have presented the detail on the crystal structure and the factor that affect the pseudo-crystal, various synthesis method i.e., solid-state, sol-gel, combustion, and co-precipitation. It has been completed with the discussion of the characteristic and the mechanism of the perovskite to separate oxygen from air

Abstract

Tartaric acid and maleic acid are carboxylic acids that effectively inhibit the growth of struvite crystals and weak organic acids that are friendly environments. The purpose of this study was to determine the effectiveness of inhibition of struvite crystal growth from the effect of adding carboxylic acid (tartaric acid and maleic acid) using batch operation which can be used as a slow-release fertilizer. Struvite is an effective phosphate fertilizer as an alternative source of rock phosphate to maintain agricultural production systems. From the results of the study, tartaric acid was found to be 10,483 mg at a temperature of 40oC with a concentration of 20 ppm and stirrer rotation of 300 rpm which was a better optimum condition to be applied in the struvite fertilizer industry when compared to maleic acid. Characterization of struvite crystals using XRPD Rietveld and SEM-EDX methods.

Abstract

Bioethanol is an alcohol molecule that is derived through the process of fermentation using microorganisms. Fermentation is a biological process in which microbes metabolize fermentable sugars as a source of nourishment, resulting in the production of ethyl alcohol and various other byproducts. These microbes commonly metabolize 6-carbon carbohydrates, with glucose being one of the most prevalent examples. Hence, biomass materials rich in glucose or glucose precursors are the most readily convertible to bioethanol. The examination of bioethanols employing Saccharomyces bayanus demonstrated notable disparities in the obtained alcohol concentration. The utilization of Saccharomyces bayanus yeast, in the absence of sugar supplementation, for the conversion of grape into bioethanol, yielded a modest alcohol concentration of merely 14%. In the context of bioethanol production, pineapple was utilized as a substrate, wherein 4 grams of Saccharomyces bayanus yeast and an additional 70 grams of sugar were introduced as a nutritional supply to support yeast growth and metabolism. The present fermentation procedure resulted in an alcohol concentration of around 21%.
