Abstract

Water is a basic necessity for people's daily lives. Each region has a local knowledge about water resources that keeps their needs met. This research explains how people in hilly lowland areas with the rivers under agricultural land can survive with their traditional knowledge. The study was conducted in Karangwangi Village, South Cianjur. Research studies have focused on different types of water sources and and utilization by the local people. The research method used was mixed-method with observational data collection techniques, semi-structured interviews and structured interviews. Based on information from the community, the water source in Karangwangi Village is not only a wahangan but also hulu cai, sirah cai, cai nyusu, wells, solokan, situ, balong and cai hujan. All of these water sources in ancient times can be used for all needs such as ibak, nyeuseuh, nginum, cooking, agriculture, fisheries. How to use it is done traditionally by using bamboo, timba, bucket. Quality and quantity of river water changes every season and the use of pesticides makes people sort water sources depend on their needs.Keywords :traditional knowledge, management water resource, water etnoecology

Abstract

Higher education is a service industry, therefore it must be able to provide excellent service. Therefore one of the lecturers’ job satisfaction must be considered. Lecturers who feel job satisfaction will work optimally. InHigher Education Z, it was found that there was an indication of the dissatisfaction of the lecturers’ work, therefore the purpose of this study was to design an Instrumenr of Lecturer performance satisfaction in Higher Education, to find out how high the level of job satisfaction was, and to identify variables from aspects that were not yet optimal Z. The method used is descriptive quantitative. The results of the analysis of the validity test, the value oh the item correlation of each variable, namely form Work, Salary and Wages, promotion Opportunities, Supervision, Co-Workers and Working Conditions by using the formula product moment r value result from 6 variables> r table (0,286) so that the design the job satisfaction instrumrnt is valid. Cronbachs Alpha value reliability test obtained Cronbach’s Alpha value greater than the critical value of (0.60). Then it can be concluded thet the items of the research instrument are reliable. Keywords : Design, Instrument, Job Satisfaction

Abstract

Indonesia is one of the largest agricultural countries in the world, with the majority of the population working as farmers. Theagricultural industry certainly needs fertilizer to maintain quality, accelerate growth and provide nutrients for plants to grow well. To provide cheap potassium sulphate fertilizer, we conducted a study on "The Effect of Temperature and Time on Yield andPurity K2SO4Fertilizer from gypsum and Ash Bark" as an alternative to commercially available ZK fertilizers. The reason we usedash bark was because it was a waste from cottonwood industry. This study used a single stage methodwhere in this method the final result was not recycled to save time.The variables used are temperature (60oC, 70oC, 80oC) and time (60, 90, 120 minutes). The results showed that the most K2SO4crystals were formed at 80oC for 120 minutes with potassium concentrations of 69.60%.Keywords: potassium sulphate fertilizer, single

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

Dyeingof wool yarn with reactive dyes is affected byfixation process with ammonium hydroxide, because it can produce good color fastness properties. The purpose of this study was to determine the effect of fixation process on wool yarn dyeing usingexhaust method withreactive dyes (Lanasol Red B), by experimenting with varying ammonium hydroxide concentrations of 3%, 4%, 5% and 6% and fixation time of 10, 20, 30 and 40 minutes. Tests carried out on color strength, colorfastness torubbing, colorfastness towashing and tensile strength of wool yarn. The resultsof experiments and tests show that the higher the use of ammonium hydroxide concentrations up to 5% and the fixation time of 20 minutes, the color strength, color fastness to rubbing and color fastness to washing increase, but using higher ammonium hydroxide concentrations and fixation time caused color strength,color fastness to rubbing, color fastness towashing and the tensile strength of wool yarnvalues relatively decreased.

Abstract

Along with the rapid development of digital technology, electronic technology which is the forerunner of information and communication technology, has been spurred on by developing miniaturization of electronic components, through the creation of integrated circuits, which at its peak gave birth to communication devices in the form of mobile phones (Cellphones / Cellphones). In its use based on macro ergonomics analysis, cell phone use is hindered by these students, giving positive and negative influences. towards its users. In this study a macro ergonomic analysis was carried out on the use of mobile phones among students, especially students of Industrial Engineering courses, Faculty of Engineering, Bandung Raya University. The purpose of this study is to analyze the positive and negative effects on the use of mobile phones among students in terms of macro ergonomics, related to the use of mobile applications in the learning process with the development of Mobile Learning through the SIAKAD and Edlink programs, and their use in relationships in the campus environment. . The research was conducted with a survey research method approach with a quantitative approach. Data obtained from the results of questionnaires that research in the field, interviews and literature studies. The results of the study showed that the results of the questionnaire test showed that the questionnaire had a level of validity of 85% and 89.6%. The results based on macro ergonomic analysis of the positive effect felt by students, in essence, is that mobile phones are very helpful in various learning process activities, academic activities and other activities in the campus environment, which is currently being promoted by the online system. The negative influence of mobile phones among students, is more on the problem of changing attitudes and behaviors of students which leads to consumptive attitudes, lazy to read text books, tend to reduce direct social interaction and less concern for the surrounding environment.
