Abstract

Food sanitation is one of the methods used to protect food from contamination, maintain quality, and prevent potential bacterial transmission. This research was conducted to observe potential diseases caused by the microbiological quality of clean water for household use. MPN method was used to compare the quality of clean water based on the Peraturan Menteri Kesehatan Nomor 416 Tahun 1990. Swab method was implemented to observe the hygiene level of the cutlery to compare with the Peraturan Menteri Kesehatan Nomor 1098 Tahun 2003. 79/100 ml of total coliform found in tenant 1 and tenant 2 which means it did not meet the standards. Escherichia coli were found absent in both clean water sources. The same result comes from 2 samples of plates and spoons before and after the first usage and second usage. In tenant 2, Escherichia coli were found in plate sample no.1 before usage and the clerk’s hands before serving the food. Hence, it did not meet the standards. Based on the interviews and observations, the sanitation hygiene of the clerks and the physical hygiene of tenant 1 and tenant 2 had only fulfilled 61.9% and 57.1% of proper hygiene, so it needed to be improved.

Abstract

Electrical energy use is an interesting topic because it is related to the operational planning of the distribution system, maintenance of medium voltage networks, and prediction of electricity consumption, especially in  the short term. Trends are created based on historical data represented in the load  curves. This research aims to determine the characteristics of the load by making load groups according to   the type of day and calculate  the load factor based on secondary data from PT. PLN (Persero) Borang substation. The research uses comparative techniques in the load groups and calculates the load factor which is the benchmark for generation  capacity. The results of the study  showed that the load trendon Singkarak feeders in  overall is the same on weekdays as on weekends, namely that  minimum load occurs in the morning at 07.00, the load starts to increase but is not significant in relation to  the activities of the population after 08.00-16.00. The load trend increases significantly from 16.00 to the peak load that occurs at 19.00-21.00 and after that, the load goes down  to the minimum load. The trend  for higher than average peak loads on Mondays is more common and weekend loads on Saturdays and Sundays only relatively small  load fluctuationsoccur.. The load group for religious holidays and national holidays received good load factor scores, with a relatively small range of loads throughout the day.

Abstract

Biodegradable plastic is an alternative to conventional plastic which has been very difficult to degrade and causes environmental pollution. Biodegradable plastic raw materials come from plants or plant wastes, so they are easily degraded by the environment and the utilization of waste becomes more efficient. The general objective of this study is to obtain the characteristics of plastics that meet the standards by varying the concentration of the materials used. This study used Kepok banana hump starch with variations in the concentration of chitosan, sorbitol, and cinnamon oil. The variable used is the ratio of weight of starch and water (1: 5). The concentration of chitosan nanoparticles was 0.25%, 0.5%, and 0.75%, sorbitol concentrations were 2 ml, 4 ml, and 6 ml, and the concentration of cinnamon was 0%, 0.5%, and 1%. Tests carried out are tensile strength, elongation of break, water absorption, and biodegradability. The best tensile strength results are 19.6 MPa, the best elongation is 47.69%, the highest water absorption is 53.77% and the lowest is 22.63%, and the complete degradation takes the longest time of 77 days.
