Abstract

Abstrak: Uji Fisis Paving Block dengan Penambahan Abu Cangkang Kerang Kepah (Polymesoda erosa). Penelitian ini adalah penelitian ekperimental yang bertujuan untuk mengetahui pengaruh penambahan abu cangkang kerang kepah (Polymesoda erosa) terhadap sifat fisis paving block. Data yang diperoleh merupakan data hasil penelitian yang dilaksanakan pada bulan september–oktober 2020 di Laboratorium UINSU-Medan.  Sifat fisis yang diuji pada penelitian ini adalah densitas, daya serap air, dan porositas.  Penggunaan abu cangkang kerang kepah sebagai pengganti sebagian semen dalam pembuatan paving block  berpengaruh terhadap nilai densitas, daya serap air dan porositas. Pada setiap variasi campuran 5-15%  menghasilkan penurunan nilai densitas yaitu sebesar 1,81, 1,77,  dan 1,62 (g/cm3), mencapai nilai standar densitas beton ringan. Untuk nilai daya serap air pada setiap variasi campuran 0-15% mengalami peningkatan yaitu sebesar 5,88, 6,26, 7,37, dan 7,58%, telah memenuhi SNI 03-0691-1996. Kemudian untuk nilai porositas mengalami peningkatan pada variasi campuran 0-15% yaitu sebesar 9,95, 10,96, 13,41, dan 14,22%.

Abstract

Research has been carried out on the manufacture of biobatteries using pineapple extract. This research aims to determine the effect of volume variations of pineapple extract solution on the voltage and current produced by biobattery. Volume variations of pineapple extract solution consisted of 50 ml, 100 ml, 150 ml, 200 ml and 250 ml. The electrodes used were copper (Cu) and zinc (Zn), the tests carried out consisted of measurements of pH, voltage, current, electric power and the length of time the voltage was lowered. The test results for the pH value of the pineapple extract solution were 3.7. The highest value of voltage, current and electrical power is obtained in pineapple extract solution because the pineapple extract solution has a higher acidity value.

Abstract : The study about the effect of the applied voltage to decrease the water turbidity from local pond and river have been conducted. This study aims to investigate the ability of the electrocoagulation process in removing pollutants containing groundwater from the pond and river. The water sample obtained from Dusun I Paya Perupuk Tanjung Pura in Langkat Regency. Indonesia which has been reported having high water turbidity. A copper plate was used as a sacrificial electrode with a specific variation of applied voltage of 6, 9, and 12 Volts. The result showed that applying 9 and 12 volts of voltages were able to reduce 60% and 66% of water turbidity from water pond, respectively. In river water, both optimum applied voltages could reduce approximately 98% of water turbidity. The result indicated that the electrocoagulation process potentially devoted as an alternative way to treat the massive local groundwater.Abstrak : Penelitian mengenai pengaruh tegangan listrik terhadap penurunan kekeruhan air sumur dan air sungai pada proses elektrokoagulasi telah dilakukan.

Abstract

Research using the electrocoagulation method has been carried out to determine the results of the sample test results for BOD and COD parameters in palm oil mill effluent. The electrodes used n this method are aluminium electrodes with varying adapter voltages of 6, 9, and 12 Volts. Palm oil liquid waste used comes from PTPN IV Adolina Perbaungan. The results of the study showed that before the electrocoagulation method the BOD value obtained was 243 mg/l, while after the electrocoagulation method the best results were obtained at a voltage of 12 Volt with a value of 52,5 mg/l. The value obtained before the electorocoagulation method was carried out on the COD parameter was 649 mg/l and after the electrocoagulation method the best results were obtained at a voltage of 12 Volt, which was 110 mg/l. This shows that the parameter values of BOD and COD in processed waste have decreased and meet the wastewater quality standards for the palm oil industry, namelyb 100 mg/l and 350 mg/l. The higher the value of the applied voltage, the more optimal the levels of BOD and COD.

Abstract

The need for an electrical energy source is currently a very necessary thing, therefore researchers conducted experiments on the use of pineapple peel (ananas  comosus) extract as an electrolyte solution with a variety of electrodes. This research was conducted with the aim of generating voltage, electric current, and strength values. The measure of the holding capacity of the solution used were 50 ml, 100 ml, 150 ml, 200 ml, and 250 ml. The electrodes to be used are in the form of copper-zinc, copper-iron, and copper-aluminum pairs with each plate measurement of 4 cm × 7 cm, thickness of 0.2 mm. To determine the magnitude of the value of the voltage and current, a resistance is given in the form of an LED lamp. Based on the results of the research the pH measurement of the solution was 3.9. The test results obtained by the pair of Cu:Zn plates are the best compared to other pairs of plates, namely by producing a voltage of 1.59 Volts, a current of 0.28 mA, and an strength values of 0.44 mW with a volume of 250 ml. This is due to the influence of the volume of the solution and the electrodes used, that the more plates submerged in the solution, the greater the energy produced.
