Abstract

In this study, the addition of aluminum (Al) and magnesium (Mg) at the zinc (Zn) electrode as the sacrifice anode in an alternative sea-based electrical energy system was carried out. The sacrifice anode method is used as a way to prevent the corrosion of Zn electrodes. There are 3 types of electrode treatments, namely Cu-Zn, Cu-ZnAl, and Cu-ZnMg. The tool is designed to have 20 cells arranged in series and given a load of 3 Watt LED lights. Tool testing is carried out for 72 hours with electrolyte replacement every 24 hours. The measurement results showed that the Cu-ZnMg electrode produced the highest power output compared to the Cu-Zn and Cu-ZnAl electrodes. The maximum value of power from the Cu-ZnMg electrode is 125.71 mW while the electrodes of Cu-Zn and Cu-ZnAl have maximum power values of 49.49 mW and 52.48 mW respectively. The value of the intensity of the light generated from the instrument shows that the greater the power released, the higher the intensity of light. The lowest corrosion rate was generated by the Cu-ZnMg electrode of 0.079 mm/year after 72 hours of testing. This shows that the addition of sacrificial anode metal with a higher potential electrode value can produce higher and longer electrical energy and a lower corrosion rate

Abstract

The electrical characteristics of filtered seawater can be determined by using Cu-Zn electrode pairs. Seawater is filtered by using a 1 micron sediment filter. Measurement of electrical characteristics of water is carried out using a 3 watt DC LED load and when the load is removed. The electrolyte cell consists of 40 cells, which are arranged in series and parallel with 300 ml per cell. Tool testing is carried out for 144 hours with 6 times electrolyte filling every 24 hours. The test results show that the longer the tool is used, the more electrical characteristics produced will be decreasing. The produce of maximum voltage (Vbl) by seawater is not filtered with a series of 31.5 V. The produce of maximum power (P) by seawater is not filtered with a series of 101.1 mW. The produce of maximum illumination by seawater is not filtered with a series of 426.4 Lux, the duration of the light is 8 hours. Despite the produce of maximum illumination by filtered seawater with a series of 319.7 Lux series, the duration of the light is 11 hours.

Abstract

Bio-battery is a battery with paste that is made of natural materials. Bio-battery produce electrical power by using electrolyte cassava pulp and Cu-Zn electrode. Design of bio-batteries are made by 20 cell of dry cell battery type R20S IEC/UM-1/D 1,5 volt and arranged in series. Cassava pulp variation are new cassava pulp and pulp with fermentation for 48 hours, 96 hours, and 144 hours. The measurement of the electrical characteristics using 7 watt LED DC for 12 hours. The maximum voltage when the load is released which genereted by new cassava pulp is 16,76 volt, fermented for 48 hours is 19,28 volt, fermented for 96 hours is 20,00 volt, and fermented for 144 hours is 20,30 volt. The variety of cassava pulp which has the best electrical characteristics is fermented cassava pulp for 144 hours. It could turn on the lamp with bright lights. The results showed that the longer the fermentation time of cassava pulp caused the electrical conductivity was increased.

Abstract

Telah direalisasikan sitem elektrolit berbasis air laut dengan penambahan variasi Alumina. Penelitian ini bertujuan untuk mengetahui alumina terhadap karakteristik tegangan dan arus yang dihasilkan. Variasi alumina yang digunakan yaitu sebanyak 2 gram dan 4 gram. Proses pengujian dilakukan menggunakan 40 buah sel elektrolit dengan sepasang Zn dalam tiap selnya. Waktu pengujian dilakukan selama 48 jam dengan pergantian elektrolit sebanyak 2 kali untuk tiap variasi alumina. Hasil pengujian relatif sama yaitu menghasilkan tegangan sebesar 26,9 volt elektroda Cu-dan arus sebesar 2,5 mA untuk tiap variasi alumina, sehingga diketahui bahwa alumina yang di berikan tidak memberikan perubahan yang signifikan terhadap hasil tegangan, dan arus.

Abstract

Penelitian ini dilakukan untuk mempelajari penggunaan magnesium (Mg) sebagai anoda tumbal untuk melindungi Zn yang digunakan sebagai anoda dalam sel elektrokimia untuk menghasilkan energi listrik dari air laut. Sebagai katoda digunakan Cu yang dilapisi dengan logam Ag untuk melindunginya dari korosi katodik. Sel elektrikimia dirangkai terdiri dari 20 sel yang disusun secara seri, dan masing-masing sel diisi air sebanyak 300 mL. Sel elektrokimia dihubungkan dengan beban LED 3 watt 12 volt selama 72 jam dan pengambilan data karakteristik listrik meliputi tegangan, arus, dan intensitas cahaya, setiap 1 jam. Dari data tegangan dan arus, dihitung besarnya hambatan dalam. Hasil penelitian menunjukkan bahwa penggunaan Mg sebagai anoda tumbal menghasilkan data karaktersitik listrik yang lebih besar dibanding dengan sel elektrokimia tanpa penggunaan anoda tumbal.

Abstract

Coffee skin contains cellulose, reaching 49%, so the material has the potential to be used as a substitute for the main material of wood in the paper industry. To obtain pure cellulose coffee skin, the lignin delignification process was carried out using 15% NaOH. Then, it was bleached by adding 10% H2O2. The bleached precipitate was washed to a neutral pH and dried. Coffe Skin Cellulose mixed with sago starch as an adhesive was weighed in a ratio of 1:3. To improve the quality of the paper, the material was mixed with a solution of Ag+ ions in a ratio of 2:1 to form pulp.The process of making an Ag+ ion solution involves forming two AgBr plates into electrodes with a distance of 1 cm in 400 ml of aquades. The electrolysis stage used V = 25 volts by checking the concentration of the solution using a TDS meter every 10 minutes. Then, the electrolysis solution underwent four variations in concentration, namely 18, 21, 24, and 27 ppm. Next, the paper is printed and dried using sunlight. This study reviewed the effect of variations in the concentration of Ag+ ion solutions coated on paper on functional groups and antibacterial properties. The results of UV-Vis analysis revealed Ag+ ions in the wavelength range of 400–439 nm. As the concentration increases, so does the absorbance peak. Then, functional group analysis indicated a shift in the absorption band peak of the N-H bending group due to reduced binding by Ag+ ions. In the results of bacterial testing, all samples had clear zone values, with an average diameter of Bacillus sp. 3.7 mm and Escherichia coli 4.65 mm. The ability of paper samples to inhibit bacteria was still weak. Keywords: Paper, Ag+ ions, Cellulose, coffee skin, antibacterial.
