Abstract

Pemanfaatan potensi sumber daya laut saat ini masih berpeluang besar, misalnya pemanfaatan air laut yang kaya akan bahan mineral mikro yang sangat berguna bagi kehidupan belum banyak dilakukan. Penggunaan air laut untuk pertanian sudah mulai dikembangkan, baik secara skala riset maupun aplikatif. Disisi lain Indonesia juga memiliki permasalahan yang juga menjadi isu yang sama di banyak negara yaitu isu pencemaran akibat sampah. Berdasarkan peluang potensi pemanfaatan air laut dan pemecahan permasalahan sampah organik yang ada tersebut, sangat penting untuk segera dilakukan, sebagai bentuk perwujudan dalam mendukung rencana pemerintah melaksanakan program pembangunan berkelanjutan dalam hal konservasi lingkungan  berbasiskan cleaner production agar memberikan kontribusi positif bagi masyarakat dan lingkungan. Penelitian ini bertujuan untuk:menentukan pengisolasian senyawa mineral dalam tablet dan menentukan efektifitas tablet sebagai pupuk tanaman tertentu. Penelitian ini dilakukan menjadi tiga tahapan, yaitu: (1) tahap persiapan bahan, (2) tahap imobilisasi/proses pentabletan air laut, (3) tahap pengujian dan interpretasi hasil. Hasil dari penelitian didapatkan bahwa Pori – pori pada permukaan serbuk sampah organik memiliki kemampuan untuk mengadsopsi unsur-unsur mineral pada air laut. Sampah organik mengadsorpsi berbagai mineral yang terdapat pada air laut sebagai primary macronutrient, secondary macronutrient dan micro nutrient bagi tanaman. Rasio air laut yang terlalu tinggi mengakibatkan kandungan Na dan Cl semakin banyak yang teradsorpsi. Skenario air laut tablet pada sampel B, sampel C dan sampel D digunakan sebagai pupuk pada dosis  5 tablet  (@500 mg) tiap 10 hari mempunyai nilai efektifitas terbaik pada sampel C  dengan efektifitas pada tanaman cabai dan terong ungu sebesar 76,47% dan 80,00%. Air laut tablet dapat digunakan sebagai pupuk tanaman.ABSTRACTUtilization of the potential of marine resources currently still has great opportunities, for example, the use of seawater which is rich in micro-mineral materials that are very useful for life has not been widely carried out. The use of seawater for agriculture has begun to be developed, both on a research and application scale. The other, Indonesia also has a problem that is also the same issue in many countries, namely the issue of pollution due to waste. Based on the potential opportunities for the use of seawater and solving the existing organic waste problems, it is very important to do it immediately, as a form of realization in supporting the government's plan to implement sustainable development programs in terms of environmental conservation based on cleaner production to make a positive contribution to society and the environment. The study aims to determine the isolation of mineral compounds in tablets and determine the effectiveness of tablets as fertilizer for certain plants. This research was carried out in three stages, that consists of: (1) the material preparation stage, (2) the immobilization/seawater tabletting process, (3) the testing phase and interpretation of the results. Results showed by the pores on the surface of the organic waste powder can adsorb mineral elements in seawater. Organic waste adsorbs various minerals found in seawater as primary macronutrients, secondary macronutrients and micronutrients. The seawater ratio is too high, resulting in more Na and Cl being adsorbed. Scenario seawater tablets in sample B, sample C and sample D were used as fertilizer at a dose of 5 tablets (@500 mg) every 10 days had the best effectiveness value in sample C with the effectiveness of 76.47% and 80% on chilli and eggplant. Seawater tablets can be used as plant fertilizer.

Abstract

Biogas is alternative energy produced from the anaerobic activity process of methane bacteria obtained by fermentation. Anaerobic activation is a sequence of microorganism processes breaking down biodegradable  materials without oxygen. Biogas is mostly produced from cow dung and tofu industry waste that has the potential to contain methane (CH4), carbon dioxide (CO2) and hydrogen sulfide (H2S). To reduce the content of (CO2) and (H2S) and to increase the element of methane gas, the purification process is needed to do. Purification can be carried out by absorption techniques using water, NaOH solution, and zeolite/silica gel. The purpose of this study is to examine the methane gas content of variations in the composition of cow dung and tofu liquid waste and the fermentation time. The method used was an experiment by varying the composition of cow dung and tofu liquid waste by 40%: 60%; 50%: 50%; and 60%: 40%, as well as variations in the fermentation time of120, 168 and 216 hours of fermentation. The results showed that the highest methane gas content in the composition of a mixture of cow dung and tofu liquid waste was 50:50 in 168 hours of fermentation which was equal to 2.806%. The content of methane gas was influenced by the fermentation time, the pH conditions in the digester, and the intensity of stirring the biogas material in the digester.

Abstract

Rice husk is an organic material that has a high lignocellulosic content so it has the potential to be turned into activated carbon. One method of making activated carbon is activation with a phosphoric acid activator (H3PO4). The purpose of this research was to study the effect of varying concentrations of H3PO4 as an activator on the characteristics of rice husk-activated carbon. The characterization refers to SNI 06-3730-1995 regarding the technical quality requirements of activated charcoal. Activation of rice husk carbon was carried out by contacting the carbon with H3PO4 for 24 hours and shaking it. The H3PO4 consisted of 3 concentration variations, namely 4M, 6M, and 8M. From the research results, the water content was 3.936%; 4.037%; 4.070%, the absorption of iodine has met the character of activated charcoal according to SNI, namely 1217.204 mg/g; 1204.255 mg/g; 1184.832 mg/g while the ash content value does not meet the SNI standard, which is still above 10%. The highest adsorption capacity and adsorption efficiency could be activated with 8M H3PO4, namely 22.42 mg/g and 89.68%. IR spectra on activated carbon with three variations of H3PO4 concentration showed the presence of aromatic C-H, C=C, and C-O anhydride functional groups.
