Abstract

The growing population and the increasing culinary industry have resulted in the production of used cooking oil (cooking waste) in large quantities. This cooking oil if consumed many times will cause disease so that it can disturb health, but if it is thrown away into the environment it will cause environmental pollution. To overcome this, it is necessary to strive for used cooking oil to be processed into ingredients that have added value. One of the uses of used cooking oil is as raw material for making solid soap. The method used is through the safonification reaction. First some reagents needed such as Sodium Hydroxide, filtered cooking oil, fragrances and natural dyes, are put into a container, then stirred, molded, then left until the soap hardens. The results show that the formed soap meets some basic criteria of solid soap with aroma and color that is adjusted to your desire.

Abstract

Jatiluhur Reservoir is one of the largest reservoirs in West Java which has many functions, one of which is for aquaculture with the KJA system. But along with the development of KJA activity in the Jatiluhur Reservoir it has become one of the factors causing the decline in water quality of the Jatiluhur Reservoir. Therefore the Purwakarta Regency government made a program called Operation Jatiluhur Jernih Lake through the Decree of the Regent of Purwakarta No.523.31.05 / Kep.286-DLH / 2017. This program had a purpose to curb a number of cageculture in Jatiluhur Dam. The purpose of this study was to analyze the effectiveness of the program as an effort to save the condition of reservoir water and to analyze the impact of the program to the sosio-economic condition of the farmer. The methode that used in this study was quantitavie methode based on the effectivity value from the quisioner and the qualitative method by analyzing data from interview. the results of this study indicate that the Jatiluhur Lake Operations program is running quite effectively with the acquisition of a score of 60.37%, which means this program has a pretty good value in efforts to save the water conditions of the Jatiluhur reservoir. But on the other hand this program has a significant impact, especially on the socio-economic conditions of farmers such as decreasing income levels, rising potential for unemployment, increasing levels of difficulty in fulfilling the needs of life, and also reducing the supply of fish in the Jatiluhur Reservoir

Abstract

The process of producing uniforms or shirts made of 100% cotton which has a pattern of weaving or printing is very much in demand, especially in Indonesia with a tropical climate which is suitable for wearing clothes made from cotton. The need for 100% cotton fabric needs both domestically and abroad made the textile companies intensely innovate because of the connection with the quality of the cotton fabric to meet market standards and in accordance with consumer desires. There are several factors that usually affect the quality of a fabric, including dimensional stability, tensile strength and tensile strength. Anti-creasing enhancements are a form of resin refinement application intended to improve the wrinkle-resistant properties of cellulose fabrics. The purpose of this study was to determine the optimum conditions that can be achieved from the addition of anti-tangle resin substances (Acrylics NZK) to the physical properties of the fabric. The resin used was an anti-creasing resin with the trade name Ackfik NZK (Dihydroxy Ethylene Urea) using a temperature of low heating (Curing 130 C) and a concentration variation of 80, 90. 100,110 g / l. The results showed the optimum conditions achieved in this experiment were the concentration of anti-creasing agent 100g / l with a heating temperature of 130 C obtained a formaldehyde-free content of 55.80 ppm, dimensional stability of 3.2% wariness of 2.4% warp and towards the feed , tear strength of 0.640 kg of cloth towards the warp of 0.625 kg in the direction of feed, Pull strength of fabric 24.43 kg in the direction of warp 11.86 kg in the direction of feed.

Abstract

The textile and textile product (TPT) industry is one of the mainstay commodities that drive the economy in Indonesia. Export market opportunities are very open for this commodity, but the current problem is the waste generated from this industry. PT.Vonex is a textile industry with spinning and dyeing products. Textile liquid waste produced has a very concentrated color characteristic and when the dye enters the waters it can cover the surface of the water body so as to block sunlight from entering the waters. Textile wastewater treatment with the sono-Fenton method as DCA (Decolorizing Agent) can be used as an alternative choice in overcoming these problems. In this study, an analysis of the reduction of the dye was carried out by using variations in the concentration of Fenton's reagent and the length of sonication time. The variations in the concentration of Fenton's reagent used were 1:1, 2:1, 4:1, and 6:1 while the sonication time used variations of 10, 30, 60 and 90 minutes. The test results show that the use of Fenton's reagent assisted by ultrasonic waves (sonication) in textile wastewater treatment can reduce the levels of color values, pH, COD, BOD, and TSS. The results showed that the variation of Fenton reagent concentration 1:1 with a sonication time of 30 minutes was the optimum condition with a percentage decrease in color value of 99.61%, a decrease in pH value of 68.94%, a decrease in COD value of 90.64%, a decrease in BOD levels by 97.48%, and a decrease in TSS levels by 91.28%.

Abstract

Environmental problems such as erosion, flooding, are mainly caused by human activities itself. Due to main environmental problems mainly came or originated from man, the solutions or prevention effort to repair the environment, must involve human factors in its planning. In Indonesia in general, including in Bendungan Village, limited insight, lack of skills, poor health, and a low work ethic are all internal factors that cause environmental problems. Furthermore, the lack of knowledge about the environment is one of the causes of the emergence of environmentally destructive behavior that is carried out unconsciously. One of the problems in this village is garbage, people throw garbage into drains and empty land because they are not aware of the consequences of their actions. One solution that exists to solve environmental problems by involving human factors in it is through capacity building, one of which is through a sustainability education and incentive given by the West java Government. Through this concept, citizens are given education about the impact of their previous behavior, one of them is the behavior of littering. The program also provides economic value to waste so that there is an incentive to maintain the condition or waste managing waste in their village. This research used Mixed Methods approach (quantitative and qualitative) and use secondary data review, direct observation and semi semi-structured interviewing to collect the data. This research found that the main factor for the success of this program is the people who willing to be open concerning the program and its concepts, thus becoming aware about their environmental problems, they willing to work for the benefit of their village. In this village the push factor are economic and re-education aspects that move the people to save their environment. The economic benefit from garbage bank also have helped this program. The obstacles to the program in this village are the lack of facilities that they have, and for cadres to teach people about the environment, the lack of the government to provide formal education for the people and the last obstacle of this program is the economic factor, low amount of sellable garbage such as PET and cans have become major obstacle in promoting garbage bank.
