Abstract

Bioetanol merupakan merupakan salah satu energi alternatif pengganti minyak bumi. Komponen utama pada limbah pertanian dan industri yang digunakan untuk produksi bioetanol adalah lignoselulosa yang terdiri dari selulosa, hemiselulosa dan lignin. Kelapa menghasilkan ampas kelapa yang dapat diolah menjadi bioetanol. Etanol dibuat dengan proses fermentasi dengan bantuan Saccharomyces Cereviciae. Penelitian ini bertujuan  mempelajari  pemanfaatan ampas kelapa untuk dibuat etanol dengan proses fermentasi dan mempelajari pengaruh waktu dan massa ragi  yang berpengaruh terhadap volume dan kadar alkohol.  Percobaan dilakukan dengan penyiapan ampas kelapa, selanjutnya ampas kelapa disterilkan dan didelignifikasi, dituangkan kedalam erlenmeyer  bersama ragi  (5 gr, 7.5 gr, 10 gr, 12.5 gr, 15 gr), waktu operasi (4 hari, 5 hari dan 6 hari),  pH 4, kemudian analisa kadar etanol menggunakan alat kromatografi gas. Hasil percobaan menunjukkan bahwa percobaan pada massa ragi 15 gr dan waktu fermentasi hari ke enam memberikan volume alkohol 3,6 ml dan kadar  alohol tertinggi yaitu 9,49%.

Abstract

Kayu karet yang menjadi produk samping dari tanaman karet biasanya akan dimanfaatkan untuk mabel, pulp dan kertas, serta arang aktif. Sedangkan pemanfaatannya sebagai bahan bakar alternatif  masih sedikit. Penelitian ini dilakukan untuk mengetahui kualitas briket bioarang yang dihasilkan dari pemanfaatan kayu karet dengan karbonisasi secara konvensional dan karbonisasi pada suhu 500oC. Arang kayu karet yang telah dikarbonisasi selanjutnya disaring menggunakan ayakan 18 mesh, dengan variasi komposisi arang kayu karet dan perekat tapioka yaitu 100%:0%, 85%:15%, 80%:20%, 75%:25%, 70%:30%, 65%:35%. Berdasarkan hasil analisa yang didapat dari penelitian briket bioarang kayu karet, kualitas briket bioarang yang terbaik ditunjukkan oleh karbonisasi pada suhu 500oC dengan komposisi arang dan perekat 100%:0%, kadar air lembab 6.27%, kadar zat terbang 24.75%, kadar abu 5.06%, kadar karbon tetap 63.92%, dan nilai kalor 6346 kal/gr.  Kata kunci: biobriket, kayu karet, perekat tapioka.

Abstract

The cement production process is one of the most energy and cost intensive in the world. In order to produce clinker, a cement industry requires the substantial energy consumption. About 70% of energy consumption lies on the unit of rotary kiln system. The higher amount of energy consumption is due to the lack of work efficiency tools leading the waste heat. This reserach was focus on modeling of the waste heat recovery in the rotary kiln system using CFD. Analysis of mass and energy balance was used to determine the sources of heat loss from kiln system. The results showed that the distribustion of the input heat to the system is a good agreement with the output energy and gave the significant insights oft the reasons for the low overall system efficiency. The system efficiency is obtained of 53 %. The major heat loss sources have been determined as kiln exhaust (21.88% of total input), cooler exhaust to stack (9.62 % of total input) and heat loss astemated as heat from kiln surface (13.54 % of total input). The amount of heat energy can be absorbed by air amounted to 163,080 Kcal / hour and can be used as air for combustion of fuel. Based on data calculation, the amount of coal can be saved amounted to 738 kg / day.

Abstract

As we know that, urea fertilizer Industry is one of important industries for supporting food consumption. But, in manufacturing process, this industry produces a wastewater containing ammonia. Before ammonia rejected to environment, it should be treated. Biological process at perforated plate with foam as attachment media and addition of ammonia degrading isolate is used as an alternative treatment with observing the effect of residence time and initial concentration of NH3-N on its pollutant degradation. From this research, biological process occur with residence time of 63 to 250 minutes and range of initial concentration from NH3-N 276 to 530 mg/L. The results are as follows: removal of ammonia of 20.92 – 56.52%, COD of 48.46 – 74.52 %, and TKN of 17.69 – 44.89 %.

Abstract

Population activity which tends to centralized in certain area cause decrease in air quality due to exhaust gas from transportation vehicle. From 2011-2014, Palembang city transport growth 3-5% per year comprise of passenger transportation, buses, truck, motorcycle and special vehicle. The increase of vehicle in Palembang gave the city air pollution potential. Transportation is the main source of air pollution in big city with 70% contribution. Exhaust gas from transport activity consist of 60% CO and 15% incomplete combustion of hydrocarbon such as NOx and Sox. The aim of research is to analyzed air quality in Palembang city. Samples were taken and subject to analysis for SO2, NO2 and CO. Sample location were determined by using purposive sampling. Location was chosen by means of traffic density at least for one hour and took place at Charitas crossroads, Patal intersection, Mesjid Agung circle, Lemabang crossroad and Plaju intersection. Result of analysis showed SO2 level is at range 112-208 mg/Nm3/hour. NO2 level between 45-227 mg/Nm3/hour and CO at range 12.595-18.320 mg/Nm3/hour. All parameter of air quality obtained are below threshold value defined by government regulation (GR) on air quality No 41 year 1999.

Abstract

Research had been carried out on tidal marshes condition at tertiary channel Muliasari Village and the effect of land user behavior on water and soils quality. The aimed of research is to evaluate water and soil quality and potent pollution due to fertilizer and pesticide utilization. The research methods are survey and qualitative approach using observation and directed interview with questionnaire aid. Water and soils samples were taken by purposive sampling method. Measurement obtained soils has pH 4.59 and 3.92 for TC4 and TC5 respectively. Cation exchange capacity is 21.65 mg/100 g or TC4 and 20.62 mg/100 g for TC5. C-organic contained in both TC4 and TC5 are very high whereas Total-N is moderate hence ratio C/N has moderate value. P2O5 detected as 81.55 ppm at TC4 and 36.06 ppm at TC5. According to Soils Research Centre Bogor, TC4 and TC5 has moderate value of N (35%) while P and K very high (81.55 ppm and 103.32 ppm). Scoring result concluded that soils is in good health and has 76% (TC4) and 73% (TC5). Storet method confirmed score result for soils as B-class or in good condition. According to these result, TC4 and TC5 of Muliasari Village was lightly polluted and still has good prospect as crops land. Key Words: Tidal zone, Water quality, pollution

Abstract

Nowadays, environmental pollution caused by industrial wastewater is quite apprehensive. Most of textile industries used synthetic dyes. Procion red is one of the synthetic dyes that often used in textile industries and classified as a reactive dye that is difficult to decompose in nature and contain harmful toxins. One of the colored wastewater treatment process is by using Fenton reagent and TiO2 catalyst (Fenton-TiO2) as one of Advanced Oxidation Processes (AOPs). The objective of this research is to treat of procion red synthetic dye by using Fenton-TiO2 method and study the effect of procion red concentration, reaction time and the concentrations of TiO2 catalyst on color and COD degradation. In this experiment, the concentrations of procion red were varied between 150-300 ppm, the concentrations of TiO2 catalyst were varied from 0.05 to 0.4% (w/v) and the reaction time of 5 to 20 minutes. The optimum condition was achieved by using procion red concentration of 150 ppm with TiO2 catalyst concentration of 0.4% and reaction time of 20 minutes, which the maximum color and COD degradation of 98.67% and 92% were achieved respectively. This condition was applied to the real wastewater of textile home industry in Palembang. The color and COD degradation of 59% and 44% were found respectively after 220 minutes of reaction.
