Abstract

Ngringo River is one of the major rivers in Karanganyar Regency. There are various activities along the river, including domestic and industrial activities where waste discharges enter the river body, causing a decrease in water quality. One of the microorganisms contained in domestic waste that acts as an indicator of pollution in the Ngringo River is Fecal Coliform bacteria, so it is necessary to calculate the total Coliform to determine the presence of pollution in the Ngringo River. The purpose of this study was to determine the total abundance of Coliforms, BOD (biological Oxygen Demand) levels and water quality status based on PP RI No. 22 of 2021. Sampling method used in this study was a random sampling. Sampling consisted of 2 place, namely upstream and downstream. The results showed that the BOD (biological Oxygen Demand) value in the upstream part of the Ngringo river was 1.08 mg/l and 3.40 mg/l downstream, while the Fecal Coliform value in the upstream part of the Ngringo river was 16000 MPN/100ml. and in the downstream part of 5400 MPN/100ml. Based on research results that BOD still meets the quality standard according to PP RI Number 22 of 2021 while the Fecal Coliform value does not meet the quality standard according to PP RI Number 22 of 2021 which means there is pollution in the river Ngringo.AbstrakSungai Ngringo merupakan salah satu sungai besar di Kabupaten Karanganyar. Terdapat berbagai aktivitas di sepanjang aliran sungai tersebut, diantaranya aktivitas domestik dan industri dimana buangan limbah masuk ke dalam badan sungai sehingga menyebabkan penurunan kualitas perairan. Salah satu mikroorganisme yang terkandung dalam limbah domestik yang berperan sebagai indikator pencemaran di Sungai Ngringo yaitu bakteri Fecal Coliform sehingga perlu dilakukan perhitungan total Coliform guna mengetahui adanya pencemaran di Sungai Ngringo. Tujuan dari penelitian ini adalah untuk mengetehui total kelimpahan Coliform, kadar BOD (Biological Oxygen Demand) dan status mutu air berdasarkan PP RI No 22 Tahun 2021. Metode sampling yang digunakan dalam penelitian ini yaitu metode random sampling. Pengambilan sampel terdiri dari 2 tempat yaitu hulu dan hilir. Hasil penelitian menunjukan Nilai BOD (Biological Oxygen Demand) pada bagian hulu air sungai Ngringo sebesar 1,08 mg/l dan pada bagian hilir sebesar 3,40 mg/l, sedangkan Nilai Fecal Coliform pada bagian hulu air sungai Ngringo sebesar 16000 MPN/100ml dan pada bagian hilir sebesar 5400 MPN/100ml.

Abstract

The aim of this study was to create and evaluate the quality of organic fertilizer using Unripened coconut waste. The process involves chopping the waste into small pieces and placing it in a container or bucket. EM4 activator liquid is then sprayed onto the waste, followed by the addition of molasses. This process is repeated for the second and subsequent batches. The prepared Unripened coconut waste is covered withblack plastic to maintain anaerobic conditions and a temperature of no more than 60°C. The pile is turned multiple times to stabilize the temperature at ± 35-45°C. The first turning occurs after one week, followedby weekly turning for up to one month. The resulting fertilizer is dried through aeration, sieved, and tested for quality. The water content was determined using the distillation method, while total nitrogen wasmeasured using the Kjeldahl method. Phosphorus was quantified using a UV-Vis Spectrophotometer, and potassium was analysed using AAS. The results indicate that Unripened coconut waste can be utilised as an organic fertiliser. The fertiliser is brown in colour, soft in texture, has an earthy smell, and a temperature of 28°C. The organic fertiliser contains 22.8% water, 0.833% nitrogen, 0.118% phosphorus, and 5.616% potassium. The produced organic fertilizer meets the specifications for fertilizer from organic waste based on nitrogen, phosphorus, and potassium content according to SNI 19-7030-2004.

Abstract

Biogas is an alternative energy source that can be renewed as one of the solutions for the scarcity of fossil energy. Liquid waste from industrial bioalcohol production (technically termed as “vinasse”) is potentially one of very promising raw material of biogas. Vinasse has low pH value (4-5), which is not preferable for metanogen. Therefore this study aimed to define the optimum condition for the production of biogas. The variable to be studied in this research was the influence of vinasse to water ratios on the production of biogas in a fed batch reactor. Three ratios of vinasse and water with the ratios of vinasse to water as 1:2 (R1); 1:2.5 (R2); and 1:3 (R3) were studied. As much as 500 mL of raw material was fed to bioreactor with 6 L of cow manure as starter inoculums. The reactor was fed once every three days, with the feed input as much as 500 mL. At the beginning of the process, total solid suspended (TSS), volatile suspended solid (VSS) and chemical oxygen demand (COD) were analyzed. The volume of biogas was measured every day while the TSS and VSS values were measured once a week. The results showed that the production of biogas at R1 reached 1640.95 ml on day 9 with pH 7, CH4 concentration of 9.89% and CO2 level of 36.93%. The biogas production at R2 on day 20 reached 119.67 mL with a methane content of 15.85%, 43.282% of CO2 level, and pH 5. In R3 the volume biogas generated on day 10 reached 158.24 mL with CH4 content of 35.36%; 35.27% of CO2 level and pH 7. Fed batch system was shown to reduce the effects of inhibitor.
