Abstract

The waste water of copper board etching process in Printed Circuit Board (PCB) production is kind of heavy metal waste water, that is copper, which has not been treated yet. In order to prevent the environment contamination process the waste water should be treated before thrown to environment. The kind of waste water treatment that will be applied to the waste water with heavy metal content, specially copper metal (Cu) is electrolysis method. The experiment was done in laboratory scale. The batch electrolysis reactor was used in this experiment, with the copper as katoda and stainless steel as anoda. Electrolysis process was conducted with waste concentration variation that was equal to 124,16; 110,96 ; and 35,84 ppm. The result of the experiment shows that, the electrolysis methode could reduce copper concentration in the waste water of etching process. The biggest efficiency degradation for the variation of waste concentration was happened at waste concentration 35,84 ppm, that was equal to 100%, with end result equal to 0 ppm. Waste concentration equal to 124,16 of ppm its result 96,24 ppm, and for concentration 110,96 ppm was got by result 0,35 ppm.

Abstract

New and Renewable energy is not only an alternative energy that can meet increasing energy needs, but also green energy that does not cause harmful effects on humans and the environment such as energy derived from fossils. The application of solar cells as a source of electrical energy to modern agricultural systems, especially the aquaponics system is one of the efforts to develop new and renewable energy that is environmentally friendly. This research is a technological innovation that can cover the weaknesses of aquaponic systems in general by using solar panels to convert solar energy into electrical energy and equipped with water circulation automation technology so that the water needs are always guaranteed. The design of automatic water circulation regulator hydroponic planting method uses a timer as an automatic, solar panels as energy converters, solar charge controller as a regulator of electric current balance. The implementation of this research consists of several stages, namely: the initial data collection stage, the system development stage, and the research data collection stage. The results showed that the water pump in the aquaponic fish pond on the first, second and third days showed that the water pump was 12 V and the average flow of the fish pond water pump was 1.15 A. The data also showed that The highest measurement carried out for 3 days resulted in an average voltage of 12.68 V and a current of around 1.75 A, and the lowest measurement produced an average voltage of 12.42 V and a current of around 1.63 A. Based on the data in the study this, solar panels with a large 50 wp can meet the load requirements (water pump) to operate so that they can help circulate water in aquaponic installations.

Abstract

Reserves of fuel oil, especially those from fossil fuels, are dwindling, while the people's need for fuel oil is increasing. Dependence on fossil fuels needs to be addressed immediately. So it is necessary to develop renewable energy sources as alternative energy to replace fuel oil. One of them is by utilizing bioethanol as an alternative. The process of making bioethanol involves a distillation process. In this study, the design and performance test of an electric distillation apparatus was carried out by utilizing molasses as a raw material for making bioethanol. The aim is to determine the quality of the alcohol content in bioethanol which is processed using an electric distillation apparatus. Electrical distillator testing includes functional tests and performance tests. Functional testing is done by testing the components used in the tool so that it can be seen whether the tool is functioning properly. Meanwhile, the performance test of the electric distillator is an automatic performance test of a tool to produce bioethanol. The performance test procedure of the electric distillator was carried out using a bimetallic thermostat of 76ºC and 85ºC, to measure the distillation time and determine the alcohol content in bioethanol. From the results of the study, it was found that for an electric distillator that uses a bimetallic thermostat of 76˚C, the processing time of 70.43 hours produces bioethanol with an alcohol content of 61.7% and an electric distillator that uses a bimetallic thermostat of 85˚C with a processing time of 0.56 hours to produce bioethanol. with an alcohol content of 35%.

Abstract

Indonesia's energy needs continue to rise, while its fossil fuel resources are limited. The national energy mix for renewable energy programs is planned to reach 31% by 2030. Indonesia's pico-hydro potential is substantial, found in mountainous areas, rural areas, suburbs, and islands. Potential is also found in primary, secondary, and tertiary irrigation areas, small rivers, waterfalls, pond circulation, and even in rainwater gutters. The research method for identifying potential in the field used a Portable Pico-hydro Turbine (PPT 1.0) with direct testing and student laboratory experiments. The results of the pico-hydro prototype study can be used to identify 26 potential pico-hydro points, which can function as 100-watt street lighting and support student energy laboratory equipment.

Abstract

Household waste is one of the sources of waste which has a big role in environmental pollution. The community as a waste producer still lacks a high level of concern for waste management itself. Partners in this case are Bandungrejo Village Youth and Youth Youth Association of “Jaya Jaya” RT 02 RW 04 Bandungrejo Village Bayan District Purworejo District initiative to be able to manage the waste they produce so that it is not harmful to the environment while at the same time adding value to the income from the sale of processed waste. So in this case, the proposer has ideas to develop waste processing technology that can be utilized by partners in this case the community through the Appropriate Technology Application Program (PPTTG) in collaboration with the Ministry of Research, Technology and Higher Education with the House of Representatives Commission X. Activities undertaken i.e. to provide assistance in the form of an integrated waste processing machine as well as a waste management training. The tools provided include one unit of a plastic chopper machine, one unit of an organic chopper machine, one unit of an organic sieving machine, 20 unit of sorted waste bins, 20 units of composter and financial assistance for the construction of a waste processing building for the placement of these machines. This activity is expected to solve the problems of partners in waste management and improve the welfare of the community itself.
