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

The research has been carried out by utilizing pore conch shell waste using sweet potato starch to make porous Hydroxyapatite using porogen sweet potato starch by precipitation method and to determine the bioactive properties of apatite hydroxy and the growth of apatite crystals using Simulated Body Fluid (SBF). This study used wet precipitation method. The results of the analysis  using XRD show that the HAp phase has been formed. The morphology of HAp based on SEM results shows that HAp pores modification is produced in the composition of HAp added with 20% sweet potato starch with 6 hour sonication wich results in pore size from the range 0,23-3,37 µm. This result is not correlate with the theory that the best pore modification is produced in the composition of HAp added with 30% starch. This is because there are difference characters of each sweet potato used. The result of in vitro tests on synthesis HAp samples and 7 days porous HAp have shown the growth of apatite crystals in SBF solution media (Simulated Body Fluid).

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%.

Abstract

This research aims to design and design an automatic water filter and test the quality of the filtered water using an automatic filter that has been designed. The quality of the filtered water is viewed from physical and chemical parameters, both parameters are measured and observed directly at the Modern Physics Laboratory of the Faculty of Science and Technology and the Physical Chemistry Laboratory of the Faculty of Science and Technology. Based on the results of the study, it was found that the results of water quality in an automatic water filter with proof of two different samples showed that the water produced was not maximal because it had a high conductivity value and a pH value that was in the acid category. Because the water pressure that enters the filter media is too large it can stir / destroy the top layer of the filter so that the top filter cannot filter out impurities optimally.

Abstract

The use of quadrotors in various applications has made development and research in the field of drones grow rapidly. In the research and development process, a testing phase is needed to determine the flying attitude of the quadrotor. Live testing can be risky if something goes wrong. With Hardware in The Loop Simulation, it can be used as a way to minimize the occurrence of these errors. Hardware in The Loop Simulation is a combination of software and hardware simulation. The jMAVSim simulation software is connected to the Pixhawk autopilot and ground control station. The simulation results that have been obtained make it possible to carry out direct testing on the Pixhawk autopilot. From this study, the results of the quadrotor flying attitude during take-off and landing simulations show that the quadrotor is still in a stable condition with changes in pitch and roll angles of less than 1 degree.

Abstract

The availability of clean water is a basic need to meet daily needs. Therefore, the identification of groundwater and its aquifer types was carried out in Labulia, Alor sub-village, Central Lombok Region and Lilir sub-village, Membalan Village, West Lombok Region. The identification of groundwater and the type of aquifer is carried out using the vertical electrical sounding method with the Schlumberger configuration because this method can identify vertical resistivity more accurately than other resistivity methods, such as Wenner. The pseudo resistivity data obtained from these measurements is processed using IPI2Win software and progress. The result of the interpretation was that the aquifer in Olor Agung sub-village was a confined aquifer, while Lilir sub-village was a free aquifer.

Abstract

Drought usually occurs, especially during the dry season in Bontoramba, Jeneponto Regency, South Sulawesi. Therefore, it is necessary to study the potential of groundwater to meet the water needs of the Bontoramba community during the dry season. A way to identify groundwater is by using the resistivity method. This method is applied with Schlumberger configuration that gives good results vertically. The purpose of this study was to identify the potential for groundwater both in position and depth based on the results of the interpretation of measurements using the resistivity method of the Schlumberger configuration. This research is experimental research with a descriptive method. Data were processed, analyzed, and interpreted using Res2dinv. Through the results of this interpretation, modeling of the distribution of the aquifer layer in the soil is then carried out which is projected as groundwater. The results showed that the groundwater layer in path 1 and path 2 were on average at a depth of 10-30 m, path 3 and path 4 at a depth more than 30 m from the ground surface.

Abstract

The purpose of this research to analyze the effect of increasing the volume and fermentation time on the bio-battery electricity of pineapple juice. Bio-battery prototype design with acrylic size 12x5x7 consisting of 6 pair of Cu-Zn electrodes. The volume of solution used was 150 ml, 200 ml, and 250 ml. The pineapple juice solution was fermented for 3 days, 5 days, 7 days, 9 days, and 11 days. A pH meter is used to measure the acidity of the solution. Electrical measurements such as electric current and voltage with a digital multimeter. When the solution is fermented for 11 days, the maximum electrical value is obtained with a volume of 200 ml which was 4,84V; 14,58mA; and 70,57mW. In this study, increasing the volume of the solution did not have much effect on the electrical voltage. Pineapple juice bio-battery is used to turn on the red LED for 2 hours with a voltage drop of 0,01-0,04V. After reaction, the Copper was thickened due to the oxidation with the Zinc.
