Abstract

Maraknya aktivitas Penambangan Emas Tanpa Izin (PETI) yang merupakan penambangan rakyat peninggalan kolonial Belanda yang terletak di Desa Tambang Sawah, Kecamatan Pinang Belapis, Kabupaten Lebong menimbulkan permasalahan lingkungan khususnya merkuri pada perairan sungai tersebut. Sampel air dan sedimen diambil dari lima titik yang terletak sepanjang hulu hingga batas desa. Konsentrasi total merkuri pada air mulai dari hulu sampai hilir sungai batas desa berturut-turut yaitu <0,0003 ppm, 0,0004 ppm, 0,0007 ppm, 0,0008 ppm dan 0,0011 ppm dan konsentrasi total merkuri pada sedimen dari hulu sampai hilir sungai batas desa berturut-turut yaitu 1,34 ppm, 4,18 ppm, 35,89 ppm, 50,32 ppm dan 114,37 ppm dimana kondisi ini melebihi ambang batas yang ditentukan . Peningkatan konsentrasi merkuri dari hulu sampai hilir sungai  ini dikarenakan terjadinya akumulasi kegiatan pertambangan emas rakyat yang menggunakan merkuri dan melepas limbahnya ke sungai

Abstract

Pressure Vessel is a vessel to contain both liquid and gasses. The storage tank is one of the tools to contain fluid, so it is an important factor in an industry such as chemistry, oil, and power plants. Biodiesel is an alternative fuel made from vegetable oil that is environmentally friendly and can reduce exhaust emissions in diesel engines. Biodiesel is renewable and reduces engine performance, so it can be used as a solution to overcome the reduced fossil fuel reserves. It is necessary to determine the corrosion rate of biodiesel. This research was conducted by storing biodiesel in the sample tank for 0 day, 1 day, and 4 days after that, the ASTM D-130 copper strip corrosion test was carried out for 3 hours ± 5 minutes. From the research, we know that corrosion rate at indoor had been stored for 4 days and for outdoor at day 0,1 and 4 gets greater corrosion with result 1b( dark orange).

Abstract

Organic waste that is not utilized will cause stinky odor. The Organic waste, especially liquid one,  has high COD. This kind Wastes with high COD are usually left not easily decomposed and those that live in the environment are anaerobic microbes which normally produce gas in metabolism. The gas usually consists of H2S and NH3 which give off an unpleasant odor. Handling of this organic waste by using a microbial source from cow dung can direct the waste conversion process to produce the main product in the form of methane (CH4). Preliminary study of liquid waste management from palm oil mill effluent (POME) in its handling. The initial conditioning was carried out by incubating cow manure and adding POME gradually by maintaining the pH of the media around 6.5. Uncontrolled treatment with a pH that did not change much from the initial pH of POME, which was between 4 - 5.5. The resulting biogas pH can reach 5.5 - 6.5 with CH4 when it is around 50%. Meanwhile, pH 6.5 - 7.5 gave the best biogas yield, namely 60%, even in the best conditions the CH4 concentration could reach 62.34% at pH 7.6.

Abstract

Kenaf core is waste from the kenaf plant at fiber process. The utilization is still very limited, while the number is increasing due to the increasing number of fiber processes from kenaf plants to become rope or raw materials in the textile industry. However, the textile industry also produces dye waste which is harmful to the environment. Therefore, this study aims to utilize kenaf core as an adsorbent for the congo red dye. The adsorption of the congo red dye by the kenaf core used a variation of the initial concentration and the duration of the adsorption process. Adsorption experimental data showed a decrease in dye concentration from up to 2 ppm, with decolorization reaching 96%. This study proves that kenaf core potential to be used as dye adsorbent.

Abstract

Penggunaan plastik sebagai kemasan produk menyebabkan meningkatnya beban lingkungan karena sulit mendegradasikan plastic tersebut. Tuntutan untuk menjaga lingkungan menjadi pemicu  melakukan penelitian untuk membuat substitusi plastic yang ramah lingkungan. Edible film dari bahan baku karagenan ( yang berasal dari rumput laut) menjadi salah satu alternative. Pada penelitian ini kami melakukan kombinasi karagenan dengan tepung konjak untuk mendapatkan karakteristik yang lebih baik. Tepung konjak merupakan tanaman iles iles (Amorphophallus) yang banyak mengandung umbi glukoman berupa heteropolisakarida yang terdiri dari β-D-glukosa (G) dan β-D-manosa (M) dengan rasio perbandingan 1:1,6. Tepung konjak dapat berfungsi sebagai bahan pengental, pembentuk gel, dan pengikat air. Tujuan pada penelitian ini yaitu untuk mengetahui  kondisi karakteristik edible film dengan cara mengkombinasikan kandungan antara bahan dasar karagenan dengan tepung konjak  dan mengvariasikan konsentrasi gliserol untuk  mendapatkan tekstur jelly dan karaketristik yang lebih baik. Pada penelitian ini menggunakan 2 parameter yang divariasikan yaitu Kombinasi tepung konjak dan karagenan dengan perbandingan 1: 1, 1: 2 dan 1:3 dan konsentrasi gliserol yaitu 5 %, 10% dan 15 % dengan kondisi yang dikontrol yaitu temperature campuran 85°C, Temperatur pengeringan 50 °C selama  24 jam. Penelitian ini menghasilkan data korelasi yaitu terhadap penambahan tepung konjak menyebabkan kadar air dan daya larut air meningkat serta  laju perpindahan air menurun dan tidak berpengaruh pada ketebalan edible yang terbentuk.  Sedangkan gliserol, semakin rendah konsentrasinya menyebabkan  kadar air rendah, ketebalan edible film menurun, laju perpindahan air semakin naik, serta daya larutnya mengecil.

Abstract

POME as liquid waste from palm oil processing has a high organic content so it is suitable for anaerobic digestion process to produce biogas and bio-hydrogen. This study aims to prepare activated sludge from biogas starter which will be used for bio-hydrogen production. The production of biogas starter with cow dung using POME as feed and the addition of nutrients (urea and DAP) at a certain ratio and buffer (soda ash) was carried out in a fermenter with a capacity of 1 m3 using a fed batch system. During one month of fermentation, methane concentration in biogas increased and stabilized until it reached the highest concentration at 33,7%. The fermentation process also produces hydrogen whose concentration decreases with time because hydrogen-producing microbes are dominant at the beginning of the fermentation, but then the hydrogen produced was consumed by methanogenic bacteria to produce CO2 and CH4. This confirmed that the activated sludge produced from the 1 m3 fermenter contained hydrogen-producing bacteria which were then further processed, one of which was heating at a certain temperature, to suppress the growth of methanogenic bacteria.

Abstract

Literature studies show that the nutrient content in tofu pulp is still high; however the utilization of this waste is still relatively low by the community. Nowadays, tofu dregs is still widely used as an ingredient for animal feed. Some of the reasons why people don't take advantage of tofu waste are consits of the funding, equipment, time and worries related to starting their own business. The aims of this study is to make a pre-designed tofu dregs processing plant into a multipurpose product aggregate such as sausages driven by the tofu business community. The method stage in this research is making a feasible product and process scheme, analyzing tofu solid waste in the form of a paper project and making a household scale sausage production prototype. The results of this study are able to produce a role model for tofu dregs utilization which is more  conomically valuable but still meet the standard and quality of reasonableness. The results of the role model will be disseminated by reaching out to tofu entrepreneur communities to collaborate with each other so that the utilization of tofu with high economic value can be carried out more massively, structurally and systematically.

Abstract

Plastic-based products have become daily human needs. From so many plastic products on the market, drinking bottles are one of them. Behind the color, shape and size variations that we find on the market, one thing we must know, the type of plastic base material used in making these drinking bottles and its product safety. One of the risk is the use of plasticizers as additives which work to increase the flexibility and durability of the plastic materials. These plasticizers can contain dangerous substances namely DEHP (Bis (2-ethylhexyl) phthalate), which is a type of ester phthalates. Studies conducted have found that phthalates can affect the development of the male reproductive system, or can reduce the level of the male testosterone hormone. Phthalates can cause cancer. Analysis of the levels of phthalates compounds in plastic materials can be done by the EN71-5 method. Sample preparation was carried out by extraction using a soxhlet extractor and n-Hexane organic solvent, then the samples were analyzed by GC-MS instrument. From the analysis results obtained the content of DEHP phthalates (Bis (2-ethylhexyl) phthalates) is below the Instrument detection limit or it can be concluded that the compound is not detected in the sample, so it meets the threshold for goods containing hazardous chemicals according to Regulation of the Minister of Trade No. 18 of 2019
