Abstract

Several lulurus products have been spread as the main product in skin care. Besides that, traditional scrub products have become another alternative choice for Indonesian people because they are known to have good advantages. However, this traditional scrub lacks knowledge of its composition and characteristics. One of them is Bima's signature black scrub, Lo'I Me'e. So that in this study a physical and chemical testing process was carried out on the lo'I Me'e black scrub. The research began with making scrubs, which are made from coffee, rice, and also the addition of tamarind. The formula used is a formula that is generally used as a Lo'I Me'e scrub product. The results of the study were tested for characteristics in the form of skin irritation test, moisture content, pH value test and antioxidant test (IC50). The results obtained in this study included no skin irritation from the public test results. In addition, the average water content produced is 34.4%. The resulting anti-oxidant levels show an average number of 35.20 IC50. While the pH value test produced was 5. All of these results met the Indonesian National Standard (SNI) regarding physical and chemical tests of scrubs.

Abstract

Urea is an important nitrogen source for plant but the price of urea fertilizer is relatively high. Urea uptake from urea manufacture waste water and its application as fertilizer is of high interest. The purpose of this study is to find out desorption ability of urea adsorbed porous carbon to be applied as fertilizer. Theoritically, urea released from porous carbon to environment has slower rate of mass transfer compare to conventional urea fertilizer because urea molecules in porous carbon has to pass through pores of carbon during its movement out of carbon. The porous carbon as adsorbent was made from coconut shell by pyrolysis, followed by sulfuric acid oxidation treatment Oxidation treatment carried out to extent adsorption capacity as well as to give additional sulfur nutrient when applied as fertilizer. Oxidation of carbon surface was performed using sulfuric acid (50%w) to soak porous carbon followed by heating at 90oC temperature for 2 hours. Desorption was conducted by placing porous carbon into beaker contain water and the raising of urea concentration in water recorded after 3,5,10, 30, and 60 minutes. Results reveal that the value of mass transfer coefficient (kc) and effective diffusivity (De) of urea desorption from porous carbon are 0,0293 – 0,0743 cm/s and 8 x 10-10 – 5 x 10-9 cm2/s with initial concentration of urea 1000, 2000, and 4000 mg/L. Release rate of urea from porous carbon and urea prill are 0,07 ppm/s and 1,23 ppm/s. Slower release rate of urea off porous carbon than urea prill shows the promising of urea recovery using porous carbon as slow release fertilizer.

Abstract

Activated carbon is a universal adsorbent possessing extensive function in human life. Adsorbent has been used in waste effluent treatment to adsorb variety substances mainly in the form of liquid and gas pollutants, odor adsorbent, food preservative, nutrient carrier for plant, and as fuel cell. Adsorbent is become an interest for its highly adsorption capacity due to its abundant pores on its surface resulting wide surface area, its simple manufacturing, its easy finding raw materials-even from waste material, and its relatively low cost of manufacturing. The purpose of this study is to investigate adsorption capacity and urea uptake percentage of activated carbon made from pyrolyzed firewood. The results obtained in this research are activated carbon from pyrolyzed firewood has urea adsorption capacity 0,026 mg urea/g adsorbent at urea concentration of 500 mg/L as high as 479 mg urea/g adsorbent at urea concentration of 50000 mg/L and urea uptake percentage 8,8 % v/v. This result shows that activated carbon from pyrolyzed firewood has capability to adsorb urea molecules form aqueous solution and therefore pyrolyzed firewood can be an alternative of low cost adsorbent for treating wastewater containing urea.

Abstract

Sumbawa Regency is an area with soil water content containing lime. There was even lime blockage in the pipe holes used. So this research aims to create a portable filtration device that is cheap and efficient. The aim of this research is to characterize a portable water filtration device with an innovative absorber from corncob waste. The way this research works is the process of carbonizing corn cob waste and then activating it using 0.5 M NaOH for 24 hours. The absorber is then filled into a portable filter with dimensions of 50 cm in length and 4 inches in diameter. Filtration is carried out by flowing the collected well water into the water reservoir through a filter. Tests are carried out on water that has not been passed through a filter. After that, characterization was also carried out on the water that had passed through the filter. This characterization consists of Total Dispended Solid (TDS), Temperature, pH, Ca levels, and turbidity. The TDS value obtained decreases with the increasing number of absorbers used, namely from 203, 163, to 123 ppm. In addition, the temperature of the test water has almost no change. The resulting results were temperatures of 32, 33, and 32oC. The resulting pH value shows a decrease with an increase in the number of absorbers used, namely from 8.3; 7.7; 7.3. For turbidity, there was a decrease in the turbidity rate with an increase in the number of absorbers used, namely from 0.29 NTU to 0.3 NTU, and 0.28 NTU. In addition, CaCO3 levels decreased with an increase in the number of absorbers used, namely from 330 mg/l, 290 mg/l, and 240 mg/l. This value has met the threshold set by PMK No. 32 of 2017.

Abstract

Energi terbarukan saat ini memiliki perhatian besar terhadap ketahanan energi dunia. Hal ini dikarenakan cadangan minyak berbasis fosil mengalami penipisan. Salah satu alternatif energi terbarukan adalah biodiesel. Harga produksi biodiesel saat ini masih relatif mahal. Sehingga pada penelitian ini bertujuan untuk membuat biodiesel murah dari minyak jelantah. Katalis yang digunakan adalah CaO/SiO2 dari limbah cangkang telur dan sekam padi dengan perbandingan 50:50 w/w. Penelitian dilakukan dengan pembuatan katalis dengan kalsinasi tertentu dan karakterisasi katalis menggunakan Surface Area Analyzer (SAA). Selanjutnya, biodiesel dibuat melalui proses esterifikasi dan transesterifikasi. Katalis CaO/SiO2 yang dihasilkan memiliki luas permukaan total sebesar 31,958 m2/gram. Nilai ini telah memenuhi standar luas permukaan katalis heterogen. Yield biodiesel yang dihasilkan dari jumlah katalis 5; 10; dan 15 gram berturut-turut sebesar 80%, 81%, dan 86%. Densitas biodiesel semakin kecil dengan meningkatnya kadar katalis yang digunakan. Densitas biodiesel dengan jumlah katalis 5,10, dan 15 gram berturut-turut 890, 860, 870 kg/m3. Nilai ini telah memenuhi SNI 7162:2015. Viskositas kinematik yang dihasilkan sedikit menurun dengan meningkatnya jumlah katalis yang digunakan. Viskositas kinematik yang dihasilkan dari jumlah katalis 5; 10; dan 15 gram berturut-turut adalah 3,1; 3,1; dan 3,0 mm2/s. Kadar FFA biodiesel cenderung menurun dengan penambahan jumlah katalis yang digunakan. Hasil penelitian ini belum memenuhi standar kadar FFA biodiesel yaitu maksimum 0,5 mg-KOH/g. Kadar FFA yang dihasilkan berturut-turut adalah 0,64%, 0,65%, dan 0,64%. Peningkatan jumlah katalis yang digunakan menyebabkan peningkatan methyl ester stearate. Hasil methyl ester stearat yang dihasilkan berdasarkan jumlah katalis 5, 10, dan 15 gram berturut-turut adalah 80,3%; 91,4%; dan 95,8%.

Abstract

The use of organic fertilizers in Indonesia is increasing, this is due to the scarcity of synthetic fertilizers. Organic fertilizers have their own challenges in terms of the concentration they contain. In addition, some organic materials that exist today are very abundant, so it needs to be used as organic fertilizer, one of which is betel leaf. However, betel leaf itself is an additional ingredient that can increase the existing nutrient content. In this study, analysis of the macro elements in organic fertilizers was carried out by adding variations in the amount of betel leaf raw material. The research was conducted using variations of betel leaf extract 2%, 4%, and 6%. The test analysis in this study was in the form of N, P, and K levels. The results showed that the highest N content was in the 4% betel leaf variation, which was 0.1%, the highest P content was in the 2% variation, which was 0.04%, and the highest K content was at 2% variation, namely 0.066%. From these results, it can be said that there was no significant effect of the addition of betel leaf extract on the macro-nutrient content of liquid organic fertilizer.
