Abstract

Wadi is one of traditionally fermented food types using basic materials of fish, salt, and lumu. As nutritive traditional food, wadi quality needs to be developed and maintained through social education. Wadi production innovation has not been done yet by the wadi makers since their information is limited on production techniques for better quality wadi. To promote local wisdom conservation, non-formal education for low educated-wadi makers is needed using simple media. Laboratory experiment and local wisdom-based booklet development is intended to broad their mind and skill in wadi production in the rural areas of Central Kalimantan. This development followed the model of Peck (1988). It contained non-formal product oriented-education materials for the wadi makers. The booklet has been validated by experts in community education, biotechnology, and learning media, and applied to wadi producing communities. Assessment instruments for booklet validation refer to non-textbook assessment instruments (enrichment books). The results showed that the booklet could be well accepted by the users and possessed very good criteria of understanding and readability value.

Abstract

The results of previous studies show that students of Physics Education (S1 and S2), FKIP Syiah Kuala University more than 50% do not understand the programs and roadmap of Pilar ASEAN Socio-Cultural Community as a part of the ASEAN Economic Community (AEC). The inference of those results to the implementation of learning physics and science education system needs to be implemented through a link and match learning model that can improve the ability to think critically and creatively, and students need to be trained to be problem solvers, not the problem makers.Based on these problems, through this research has been applied physics learning by using Problem Solving strategies on 25 students of Master of Physical Education and Science. At the end of the implementation study measured the ability of students to apply problem-solving strategies in accordance with Answer Sections of Problem Solving adopted from previous research. The results showed that the majority of students (78%) are able to implement the stage I (Focus on Problem) with a complete, almost all respondents (91%) was only able to implement the stage II (Describe the Physics) of about 40%, almost all respondents (91% ) can apply for the stage III (Plan The Solution) approximately 80% of all respondents have been able to implement the stage IV (Excute the Plan) perfectly, and all respondents have been able to apply the stage V (Evaluate the Answer) completely. It is expected that all staff of teaching Science materials (Physics), they are recommended strongly to implement Problem Solving as an alternative strategy for preparing students to face global competition in the ASEAN Economic Community (AEC).

Abstract

The role of scientific and technological knowledge is needed to compete in the era of industrial revolution 4.0. One of the roles of scientific knowledge is by analyzing the scientific literacy ability of pre-service physics teachers. This research aims to find out how far the achievement of scientific literacy possesses by current pre-service physics teachers. The measurement of scientific literacy encompasses two aspects, namely, competence and knowledge aspects. The subjects of this research were thirty pre-service physics teachers from Universitas Islam Negeri Raden Intan Lampung (State Islamic University Raden Intan Lampung) selected by using purposive sampling. The research instrument used in this research was a test of scientific literacy ability. The data analysis techniques used consisted of data reduction, data display, and verification. The result of the study indicated that some indicators of scientific literacy skills need to be improved. The results showed that there were differences in the achievement of literacy skills in each indicator. In the aspect of competence, the indicator of Indicating Scientific Issues aspects of competence covers identifying issues scientifically (poor), explaining phenomena scientifically (good), using scientific evidence (poor). The aspects of knowledge: content Knowledge (good), procedural knowledge (poor), epistemic knowledge (moderate). Overall the scientific literacy ability of the pre-service physics teachers has not shown satisfying results. It can be concluded that pre-service physics teachers’ literacy ability should be improved. A special strategy is needed that can improve the scientific literacy skills of prospective physics teachers so that the students who will teach in the future also could have good scientific literacy skills.

Abstract

Ex-mining pond water is widely used for the daily needs of the people these days, such as bathing, washing, and even drinking. Over time, it turns out that coal mine acid water has polluted the environment. The use of membrane technology to produce water that meets drinking water quality standards by the Minister of Health Regulation No. 492 of 2010 can be a solution to this problem. The NF270 membrane is a membrane process between reverse osmosis and ultrafiltration, which has a lower flux and operating pressure below 0.2-1.53 Mpa compared to reverse osmosis. Membrane NF270 is used for the reclamation of wastewater, water purification and softening, seawater desalination, and others. Its high rejection of organic molecules with a molecular weight of 200-2000 Da ions and multivalent can remove suspended solids, natural organic matter, bacteria, viruses, salts, and divalent ions contained in water, including coal mine acid water. The purpose of treating acid mine drainage with the NF270 membrane is to remove COD, TSS, TDS, and Fe metals. The NF270 membrane was used in this study to treat the coal mine acid water of PT. Bukit Asam. The performance of the NF270 process was assessed from the effect of pressure (4, 5, and 6 bar) on the flux and rejection rate of each parameter in a single solution, mixed and aqueous coal mine acid solution. The optimum pressure of the NF270 membrane for all parameters was 6 bar. This optimum pressure was then used to compare the phenomenon of flux that occurred and the level of rejection produced in the original sample of coal mine acid water. In the original coal mine acid water, there was a significant decrease in flux due to fouling deposition on the membrane surface. This phenomenon of decreasing flux was caused by fouling and polarization concentration. The rejection rates produced for the parameters of COD, TSS, TDS, and Fe with NF270 membranes were 56.4-93.1%; 78.5-100%; 43-69.3%; 67-100% respectively. Treated coal mine acid water using NF270 membrane technology can be used as drinking water that meets the standards of the Indonesian Ministry of Health Regulation. Thus, NF270 membrane technology can be used to process coal mine acid water into environmentally friendly drinking water.
