Abstract

This research aims to design and compare the results to the biogas reactor with a stirrer with a biogas reactor without a stirrer. The research has successfully designed a biogas reactor with a stirrer with a stirrer using a dynamo as a player with a capacity of 11 kg. From the results of tests performed 3 times a day for 9 days, had the highest pH value data obtained on day 5 is 7.5 to biogas reactor with a stirrer and a biogas reactor without a stirrer. For the measurement of temperature changes irregularly due to unfavorable weather conditions remain. For the production of biogas in the biogas reactor with a stirrer, began to be seen on day 5 with a value of 76.3 cmHg whereas the increase in biogas reactors without biogas agitator begins to form on day 7 with a 76.5 rise in value. This tool is used for testing samples of cow dung as a sample of the most nice and easy to obtain. Based on the results of research conducted, it can prove that the biogas reactor stirrer dngan able to produce biogas more quickly than the biogas reactor without a stirrer this was due to the substrate in the fermentation container tercempur homogeneously so that the bacteria is able to reproduce a whole.

Abstract

This study aims to determine the effect of NaCl concentration of sea water on the value of voltage and electric current, the amount of power produced from seawater with various concentration and duration of sea water can be utilized as a source of electrical energy. Plate copper (Cu) and plate zinc (Zn) as the electrode and the concentration of NaCl sea water used were obtained from three point locations is Tanjuang Bayam coast, Barombong coast and Je’ne’berang river estuary. The results was show that the concentration of NaCl seawater affect the amount of voltage and current value of the electricity generated is greater concentration of NaCl seawater used, the greater the voltage and electrical current was generat. For the highest concentration was obtained at the point of Cape Shaded locations with large concentrations of 3,4% and a maximum power generated 0,21072 watts while the lowest concentration was obtained at the point of estuaries Jeneberang locations with large concentrations of 3,2% and a maximum power generated 0, 20 331 watts. Effective time used for the utilization of sea water which is the average for ten days to turn on the LED (Light Emithing Dioda).

Abstract

Draining traditional boat water efficiently is sometimes considered to be of little importance to most fishermen. Because it is considered a normal thing without realizing it can be detrimental, both in terms of time and work. One of the things that often makes the use of draining water less efficient is that the draining of boat water is still done manually with human intervention. So that fishermen are preoccupied with removing puddles of boats and hindering their work. Based on the above problems, this study aims to make a traditional boat water drain control system automatically. This tool functions to control the volume of water in the boat as well as turn on and turn off the water pump engine automatically. This tool is able to remove puddles that enter the fishing boat automatically. The working principle of this tool, if the water hits the sensor ≥ 5 cm, the pump and buzzer will start and if the water doesn't hit the sensor, the pump and buzzer will automatically shut down.

Abstract

This study is aimed at knowing the problematics of german education students who have never gotten german lessons in previous education levels. This study belongs to descriptive qualitative. The population in this study is German Education students of State University of Makassar, class of 2019. The samples in the study are students of the class of 2019 who have never learned German in previous education level. The data were collected from observation and questionnaires. The results of the study are problems faced in the learning process including internal factors and external factors. The internal factors are the ability to memorize teaching materials, explore memorized teaching materials, and learning habit. Whilst external factors are academic facilities and infrastructure, teaching staff assessment policies, and the social environment on campus. The main problems are: the lack of vocabulary, difficulties in sentences structure (grammar) and the lack of ability in pronunciation.

Abstract

Nutmeg is a source of income for some people in South Aceh, and some types of nutmeg, like mace nutmeg, are of better quality. Mace nutmeg is also an agricultural community with great economic value and benefits for humans, as it can be processed into spices and herbs. A range of products includes nutmeg oil and medicines. The harvesting and drying of mace nutmeg, which is still considered a problem by nutmeg growers, cannot be isolated from the processing of the basic ingredients. The natural process of drying mace nutmeg involves the use of sunshine, which necessitates a considerable drying time. Therefore nutmeg farmers frequently complain of erratic weather, especially during the wet season. The constant rain can cause the mace to rot, causing the nutmeg farming community's revenue to become unstable. Methods and steps of research work starting from the study of literature, determination of design specifications, hardware design, software design, toolmaking, tool testing.Good results were reached with the dryness of the mace nutmeg, which can be adjusted, and without putting into account the weather in the drying process, which is usually done with the heat of the sun, per the results of the testing of the designed tools.The average dryness of mace nutmeg is at a temperature of 45 percent with a time of 4 hours and a capacity of 100 grams; according to the test results of the automatic mace drying machine, it produces 50 grams of dry mace.

Abstract

This research aims to determine the characteristics of chemical laboratory wastewater which includes COD, pH, turbidity and heavy metals (Pb, Hg, and Cd) before processing and after processing using the electrocoagulation method and moringa seed coagulant. The electrocoagulation process is carried out using a pair of electrode plates made of iron as anode and cathode with a voltage variation of 6, 9 and 12 V with each coagulation process carried out for 30, 60 and 120 minutes for each voltage variation and the coagulation-flocculation method using 2.5 grams of moringa seed powder each as a coagulant with fast stirring for 5 minutes and slow stirring for 2 minutes. The results obtained from the electrocoagulation method and the coagulant method of moringa seeds, namely with pH parameters of 5, COD of 20000 ppm, turbidity of 4.09 FTU, Hg levels of 1.2857 mg / l, Pb levels of 0.090659341 mg / l and Cd levels of 0.090659341 mg / l. This shows that the electrocoagulation method and the coagulant method of Moringa seeds can reduce each of the parameters tested, both pH, COD, turbidity and heavy metals (Pb, Hg and Cd).

Abstract

One threat today is the destruction of the environment waste pollution. Waste of mango peel, papaya peel and banana stem bark can be used to absorb heavy metals in a body of water such as waste containing cellulose and pectin. Leachate is the result of a pile of garbage that have decomposed physical, chemical and biological decay results contain harmful substances such as heavy metals. In this study attempted an adsorption method using waste mango peel, papaya peel and banana stem as an adsorbent to absorb heavy metals in leachate is adsorbat.  With adsorption process mango peel, papaya peel and banana stem as adsorbent divided into several mass size is 1, 1.5 and 2 grams with a variety of contact time of 40, 60 and 80 minutes as the independent variables in the study and the stirring speed as a fixed variable. Leachate used contain heavy metals Pb of 1.58 mg/l. After analysis using the SSA found that the highest effectiveness in the mango peel adsorb Pb, namely the addition of mango peel masses as much as 1 gram to 40 minutes of contact time with the absorption efficiency of 93.67%; the highest effectiveness in papaya peel adsorption of Pb, namely the addition of papaya mass of 1.5 grams with a contact time of 40 minutes with the absorption efficiency of 65.82%; the highest effectiveness in the banana stem adsorption of  Pb, namely the addition of banana stem mass 1 gram with a contact time of 40 minutes with the absorption efficiency of 56.33%.
