           Adsorben Pada Penjerapan Methylene Blue

    • Authors: Andi Musfirah Adhar, Isma Ayu Ningsih Putri Zainal, Farham Farham, Ida Adriani Idris, Haera Setiawati, Yuliani HR
      Pages: 1 - 6
      Abstract: Kluwak (Pangium edule) is a plant that the seeds are used as a seasoning, to produce waste in the form of kluwak shells that the application has not been widely used by the community. This study aims to utilize the carbonized kluwak shell waste as an adsorbent for the absorption of methylene blue, by activating them using potassium hydroxide (KOH) to increase the adsorption ability of the adsorbent. Variations in the concentrations of KOHused are 0, 1, 3, and 5 M and concentrations of methylene blue solution 100, 110, 120, 130, 140, and 150 ppm. The study reviewed how the characteristics of the kluwak shell as an adsorbent on the absorption of methylene blue, including absorption percentage, maximum adsorption capacity through Langmuir equation, adsorbent morphology through Scanning Electron Microscope (SEM) analysis, and surface area. The adsorption process in this study took place in batches for 90 minutes using a shaker with speed of 300 rpm with volume methylene blue solution as much as 50 mL and the weight of the kluwak shell carbon without activation, and KOH 1, 3, and 5 M activated kluwak shell carbon as much as 0.15 g. The results showed that the higher the concentration of KOH, the higher the average adsorption percentage and maximum adsorption capacity. The amount of the average percent absorption, maximum adsorption capacity, and the largest surface area were on the kluwak shell carbon activated by KOH 5 M, were respectively 97.69%; 48.082mg/g; and 174.17 m2/g. The SEM results analysis showed that activated kluwak shell carbon of 5 M KOH had a larger particle size and pore shape, had a more unified shape, and a flake structure than without activation.

  • Pengaruh EM4 Terhadap Pengolahan Limbah Cair Industri Tahu Menjadi Pupuk
           Organik Cair

    • Authors: Nabilah Rizqi Qurrotu'aini, Mintan Mawarni, Yoshua Beay, Nurrochman Nurrochman
      Pages: 7 - 12
      Abstract: Household waste contains high enough organic pollutants which can be used as raw material for liquid organic fertilizer. The addition of EM4 (Effective Microorganisms) in the manufacture of fertilizers aims to accelerate the process of making organic fertilizers effectively and EM4 can also improve the quality of the fertilizer. The method used in the manufacture of this fertilizer is an anaerobic method. The tofu industry liquid waste is accommodated in tubs that have been labeled A and B. Then the same treatment is given, namely the addition of 750 mL of coconut water for every 3 liters of tofu industrial liquid waste and 90 grams of granulated sugar in each tub. In the tub labeled B, 90 mL of EM4 was added. The tub to which these ingredients have been added is then closed tightly and fermented for 14 days. Parameters tested include pH, temperature and also levels of C-Organic. After 14 days of fermentation, the pH obtained was 4. The pH of the liquid organic fertilizer decreased because the C-Organic decomposed in the fermentation of this liquid organic fertilizer into organic acids. C-Organic content after fermentation for sample A was 0.57% and C-Organic content for sample B was 0.42%. The low levels of C-Organic are due to the addition of EM4 during the fermentation process which can break down compounds such as carbohydrates and proteins into simpler compounds that can later be utilized by plants. This standard of liquid organic fertilizer is adjusted to the Regulation of the Minister of Agriculture no. 70/Permentan/SR.140/10/2011. Liquid organic fertilizer with the addition of EM4 will affect the yield of C-Organic content.

  • Analisis Pupuk Organik Cair Limbah Industri Tahu Dan Air Cucian Beras

    • Authors: Sukmawati Sukmawati, Sufi Ainun Nisa, Ardian Desta Pratama, Fadli Nur Fauzi
      Pages: 13 - 20
      Abstract: Domestic waste contains good organic matter for plant growth. One of the domestic wastes owned by each house is rice washing water. In addition, the tofu industry is also widely found in Indonesia, one of which is Cilacap City. The content of organic matter possessed by the two wastes is a source of plants. To reduce the environment, this waste can be used as raw material for making liquid organic fertilizer (POC). In addition to being environmentally friendly, the raw materials used are also easy to find. This study aims to analyze pH, temperature and levels of C-Organic in liquid organic fertilizer from tofu industrial waste and rice washing water. The manufacture of liquid fertilizer is carried out using the anaerobic method, which utilizes bacteria that are active without oxygen through a fermentation process for 14 days. To determine the effect of adding EM4 and molasses, compositional variations were carried out on samples of liquid fertilizer, namely KO, P1, P2, and P3 with molasses volume sequentially 0 grams, 5 grams, 5 grams, 10 grams. Meanwhile, the volume of EM4 added sequentially is 0%, 5%, 10% and 5%. Measurements of pH and temperature were carried out every 4 days, but measurements of C-Organic were carried out at the beginning and end of the mini-research. The final pH of POC was in accordance with quality standards with KO = 4.5 and P1, P2 and P3 = 4. The final temperature of KO samples was 29.5ᵒC, P1 29ᵒC, P2 and P3 28.5ᵒC. The highest organic-C content was owned by the knockout sample, which was 0.00297. All samples in this mini research are not included in liquid organic fertilizer (POC) but can be classified as nutrients for soil improvement.

  • Penyisihan Fosfat dan Amonium Pada Air Limbah Menggunakan Presipitasi
           Struvite Dengan Penambahan Bittern

    • Authors: Adhi Setiawan, Falenia Firdatul Jannah, Tarikh Azis Ramadani, Tanti Utami Dewi
      Pages: 21 - 28
      Abstract: The fertilizer industry generally produces wastewater with relatively high ammonium and phosphate content, so processing is necessary so as not to cause eutrophication effects that harm the environment. Struvite precipitation with bittern media was an alternative method to remove struvite content in wastewater. This study aimed to analyze the effect of pH and molar ratio [Mg2+] : [NH4+] : [PO43-] on the struvite precipitation process in reducing the ammonium and phosphate content in the artificial wastewater of the fertilizer industry and to characterize the struvite obtained from the precipitation process. The precipitation process was conducted in batches with various pH and molar ratios [Mg2+]: [NH4+]: [PO43-]. The variation of pH used is 8−10. The molar ratios used are 1.5 : 1.0 : 1.0 and 3.0 : 1.0 : 1.0. Struvite characterization was conducted using SEM-EDX and XRD methods. The results showed that pH and molar ratio had an effect on the efficiency of removal ammonium and phosphate using struvite precipitation. The best pH value and molar ratio that can be used to remove content of ammonium and phosphate is at pH 9 with a molar ratio of [Mg2+] : [NH4+] : [PO43-] 3.0 : 1.0 : 1.0 which results in the removal efficiency of 86.50% and 99.96% respectively. The morphology of struvite obtained from precipitation is irregular rod-shaped with an average size of 28.53 μm. XRD results have detected peaks indicating the struvite phase.

    • Authors: Sopyan Ali Rohman, Abdurrahman Abdurrahman, Shafwan Amrullah
      Pages: 39 - 48
      Abstract: Household energy need in Indonesia, especially for cooking, are still dominated by LPG fossil fuels with 70% of LPG needs being imported. On the other hand, the availability of biomass waste, especially candlenut shells, is abundant. One way to optimize the use of candlenut shells is to use candlenut shells as fuel for biomass stoves by optimizing the efficiency of biomass stoves. In this study, a biomass stove with primary and secondary airflow was used with a combustion chamber diameter of 200 mm and a height of 340 mm. The biomass waste used is candlenut shells as fuel. The purpose of this study was to explain the increase in the performance of a biomass stove fueled with candlenut shell which is influenced by primary and secondary air velocity. Biomass stove testing includes thermal efficiency, specific fuel consumption, CO and CO2 emissions. The performance test results show that the biomass stove with a primary air velocity of 3.7 m/s, a secondary air velocity of 3.7 m/s has the highest thermal efficiency of 45.77%. The lowest specific fuel consumption is obtained from a biomass stove with a primary air velocity of 1.5 m/s, a secondary air velocity of 1.5 m/s, which is 0.583 kg/hour, and the emission test results show that complete combustion occurs with 0% CO emotion. on all air velocity variables studied.

      Abstract: Catfish cultivation is widely cultivated by the Indonesian people and generally uses intensive methods so as to produce high stocking densities. Fish farming activities will produce wastewater in which organic residues can accumulate from feeding fish, manure, particles of fish feed residue, bacteria, and algae. In addition, catfish cultivators utilize the remaining water from catfish cultivation as plant fertilizer without further processing. This will affect other organisms in the soil, so it is necessary to research and manufacture liquid fertilizer from water left over from catfish farming. Liquid organic fertilizer is a fertilizer derived from organic materials from plants and animals that have undergone decomposition and have a liquid form of product. Liquid organic fertilizer is made by comparing the composition of the remaining water from catfish farming, EM4, and molasses. This aims to determine the effect of bioactivators for liquid organic fertilizer with water as a base material from catfish cultivation. The composition made is 1 liter of pure wastewater (sample A); 1 liter of pure waste, 20 ml of EM4, and 20 ml of molasses (sample B); 1 liter of pure waste, 10 ml of EM4, and 30 ml of molasses (sample C); and 1 liter of pure waste, 30 ml of EM4, and 10 ml of molasses (sample D) which were then kept in the mixture for 15 days in a closed manner. From these 4 variations, the results of testing pH, temperature and also organic C content were obtained where the temperature and pH tests met the quality standards for liquid organic fertilizers, while the organic C values did not meet the quality standards for liquid organic fertilizers.

  • Characteristics Of Microbubbles Generated From Perforated Plates

    • Authors: Dhyna Analyes Trirahayu, Ridwan P. Putra, Joshua Mulia Nababan, Mubiar Purwasasmita
      Pages: 53 - 61
      Abstract: Microbubbles are emerging as versatile tools in numerous scientific and engineering disciplines. However, the applications of microbubbles in agricultural fields require a simple and cost-effective device that can be used to generate microbubbles. In this study, a new approach to producing microbubbles was developed using perforated plates incorporated with glass columns. Two different plates with various numbers of holes were fabricated. Characterization of the microbubbles showed that the diameter of the microbubbles produced was in the range of 10.4 to 21.1 µm. The gas-liquid ratio tended to increase by around 30-40%, with increasing oxygen gas flow rate and gas-jetting time. The enhanced oxygen gas flow rate and gas-jetting time also prolonged the residence time of the microbubbles. In general, this technique is promising that can be implemented in agricultural sectors, especially in hydroponic systems.

      Abstract: Pineapple production which reaches 8.75% of the total production of all fruits in Indonesia produces pineapple peel waste that has not been processed. Therefore, composting with Black Soldier Fly (BSF) larvae was carried out to overcome this problem. Variations in the composition of the compost material used in this study were one hundred percent pineapple peel, a mixture of pineapple skin and cow dung (25:75), and a mixture of pineapple skin and chicken manure (25:75). Temperature, pH, moisture content, C/N and final weight of BSF larvae were analyzed. The weight of the larvae used in each composition of the compost material is fourteen grams. The results showed that the temperature, pH, and moisture content of the compost had met the requirements according to Indonesian National Standard number 19-7030-2004. The C/N ratio of compost with 100% pineapple peel, pineapple skin and cow dung (25:75), and pineapple peel and chicken manure (25:75) were 24.6; 16.3; and 14.2, respectively. The C/N ratio of compost with a composition of one hundred percent pineapple peel did not meet the standard. Compost with a mixture of pineapple skin and livestock manure (cow and chicken) met the standard. The weight gain of the larvae in each reactor was in the range of forty to fifty times the initial weight of the larvae added to the reactor.

      Abstract: One of the fisheries and marine potentials in Cilacap Regency is tuna fisheries. Catch tuna that landed at the Cilacap Ocean Fishery Port (PPSC) is high. Based on the analysis of the needs of actors in the tuna fisheries system in Cilacap, one of the components included in the system is the tuna fish processing industry. This is because there is only one tuna fishing company in Cilacap in 2009. The existence of these problems causes an increase in the growth of the micro-industry in the tuna fish processing business in Cilacap. This increase certainly has an impact on increasing the waste generated. This study aims to identify the type of waste generated and the waste management efforts of micro-industry players (MSMEs) processing tuna chili sauce in Cilacap and analyze the appropriate management design to be applied in the tuna fish sauce processing industry. The research data collection method was carried out by direct observation by conducting interviews with the owners of MSMEs. The results of field observations on MSMEs that produce tuna fish sauce produce organic and non-organic waste and the waste is simply thrown into the environment without any treatment first. Efforts to manage waste produced by MSMEs with tuna sauce have not yet been carried out due to limited human resources in knowledge about waste management. Based on the characteristics of the waste produced, several types of designs can be carried out by MSMEs, namely the management of organic and non-organic wastes to minimize the waste generated both in terms of quality and quantity as not to pollute the environment.
