Abstract

Declining oil production in Indonesia lately has been much discussed by industrial practitioners, especially from the petroleum industry. The decrease is due to the age of old drilling wells with high water cut (> 90%), so it is necessary to pursue a production method that can increase the production of these old wells. The EOR (Enhanced Oil Recovery) method is one way of extracting oil from oil wells that cannot be further retrieved by injecting materials that are not in the reservoir. One ingredient that can be injected is Sodium Ligno Sulfonate (SLS) surfactant derived from lignin. Lignin was obtained from the lignin isolation process from Black Liquor, which in this study came from the pulp and paper mill waste of PT. Indah Kiat, Pekanbaru, Sumatra, Indonesia. This study aims to determine the effect of variations in H2SO4 concentrations (concentrations of 15%, 20%, 25%, 30% w/w) on the yield of lignin isolation results, and to compare the functional groups between dirty lignin, clean lignin, and pure lignin using FT-IR. Based on the research results, it was found that the best lignin is lignin with an H2SO4 concentration of 20%, with the highest yield and the color of lignin produced tends to be similar to pure lignin. In addition, it was found that the peak of the net lignin group had more similarity with commercial lignin compared to crude lignin. Keywords: Lignin, Black Liquor, Enhanced Oil Recovery (EOR), FTIR

Abstract

Chitosan has a lot of benefits such as antifungal, antibacterial, coatings, absorbing water and fat.Most of research to process chitosan use a waste from crustaceans such as shrimp, small crab skins, leather and other crabs. But in reality, there are many other types of arthopoda that contain chitin, for example is the class of Insecta as Tenebrio Molitor (meal worm). Meal worm contain the chitin in the skin. Meal worm  change of skin as much as 15 times before it finally turns into a cocoon. it is the waste in meal worm cultivation and still have rich in chitin. To extract the chitin into chitosan consists of three stages namely deprotenisasi, demineralization and deacetylation. Product of in this research is if with increase of consentration NaOH and increase of operation temperature so protein contain will be decrease, mineral contain so much the decrease, and deacetylation of degree be increase. Optimum condition of deproteinisation process at 3% w/v concentration of NaOH and temperature at 90 oC with protein contain 4,25%. Optimum condition of demineralization process at 2,5 N concentration of HCl with Ca contain 0,76% and Mg contain 2,44 mg/100gr. Optimum condition of deacetylation process at 5% w/v concentration of NaOH and temperature at 100oC with deacetylation of degree is 61,2% and product of rendemen is 33,1%.

Abstract

Water hyacinth population that continues to grow every day becomes a problem that must be solve immediately. One of the prospective utilization is synthesis cellulose diacetate based on  cellulose which containing in water hyacinth. The purpose of this research are to determine the potential of water hyacinth in the manufacture of membranes and determine the effect of polymer concentration and evaporation time on membrane performance. In this research, there were two series of experiments, synthesis of cellulose diacetate from water hyacinth and manufacture of membranes. Synthesis cellulose diacetate was done by two steps, cellulose insulation and cellulose acetylation. While, manufacture of membranes was done by phase inversion method, where the parameters that will be examined is the optimization point of polymer concentration 13, 14 and 15% weight as well as  evaporation time 0, 5, 10 and 15 seconds. Cellulose diacetate used as polymer, with acetone as solvent and polyethylene glycol (PEG) as additives. Characterization of membrane was done by measuring flux and rejection to separate humic acid water, and analysis using FTIR and SEM. The results showed that water hyacinth can be utilized as cellulose diacetate and has potential to be used as membranes. In addition, it can be concluded that the concentration of polymer and evaporation time have an affect to the performance of the membrane where the greater concentration of the polymer and the longer of the evaporation time caused the morphological structure of the membrane will be more dense and pores become smaller, so flux getting smaller while the rejection getting larger. Membrane with 15 %wt polymer concentration and 10 seconds evaporation time produces the best performance with flux 460,54 L/m2.hour and rejection 64,28%.

Abstract

The scarcity of fuel oil globally will need to use biofuels as a alternative fuel. One of it is bioethanol. Bioethanol is ethanol produced from sugar fermentation. Generally bioethanol made from crops like sugar cane and sweet sorghum. Though the plant has a use value as food. This can cause food prices creeping up highly interest in plants and biofuel producers to process the material into bioethanol. Cocoa plantation commodities whose role is quite important to the national economy. Components of the cocoa pod waste is the largest cocoa pod which is 75%. The cocoa pod has a coarse fiber which consists of 27,8278 % lignin, 22,852 % cellulose,and 11,9482 % hemicellulose. The content of cellulose and hemicellulose in the cocoa pod can be further processed into bioethanol by hydrolysis, fermentation, distillation and adsorption (purification). Method for the purification of bioethanol used adsoption, to separate water from ethanol compound. The study was conducted using experimental methods and performed in the laboratory of chemical engineering, University of Diponegoro. Phases of the study are preparation materials, hydrolysis, fermentation, distillation, adsorption, and analysis of results. Variables change at the time of fermentation experiments (144: 168: 192: 216) hours, but it's kind of adsorbent during the distillation of molecular sieve 3A, silica gel and a mixture of molecular sieve 3A and silica gel. Variables fixed at the stage of hydrolysis is 100 grams of cocoa pod powder, 2N H2SO4, 1 liter distilled water, 4 hours of hydrolysis time, hydrolysis temperature 100OC. Variables fermentation stage are 0.23% w S. cerevisiae, 18% glucose, 0.5% w Urea, 0.06% w NPK, pH 5. At this stage of the distillation temperature of 85 °C, the volume of 60 ml, 1.5-hour distillation time and at this stage of dehydration is 90gram weight of adsorbent, temperature 78OC. Responses were observed levels of ethanol that is produced on fermentation time and the ability of  molecular sieve 3A or silica gel in ethanol purification. The result showed that the fermentation of the cocoa pod is the best at 168 hours. Molecular sieve 3A is a better adsorbent than silica gel or molecular sieve 3A + mixture of silica gel. Fuel grade ethanol is obtained by the adsorption of the ethanol content of 95.87% to 99.16% using molecular sieve 3A.

Abstract

Waste jengkol and petai is a class of organic waste that can pollute the environment. For that pollution problemscan be overcome by utilizing the waste into liquid organic fertilizer which can raise the economic value that arebeneficial to the environment. The process of making is solid liquid extraction (leaching) with leaching timevariation, species composition and bioactivator waste type. The mixture is fermented for 25 days once every 5 daysof leachate were taken to measure the content of phosphor. Variation time of leaching showed that the longer time,more and more content of phosphorus is produced. Optimum time on the day to 25 where each variable is theamount of phosphorus in every 663.33 mg / l; 596.69 mg / l; 427.48 mg / l and 398.98 mg / l. Bioactivator type andtype of waste that is used also affects the amount of phosphorus produced. Rendement produced on the 25th dayfrom each variable is 62.07%, 48.28%, 44.83% and 37.93%. The rank of variable composition that produces a highphosphorus content and high yield is jengkol EM4, petai EM4, jengkol Boisca boisca and petai Boisca.

Abstract

Ekonomi sirkular merupakan suatu model yang berupaya memperpanjang siklus hidup dari suatu produk, bahan baku, dan sumber daya yang ada agar dapat dipakai secara berkelanjutan. Salah satu implementasi ekonomi sirkular yaitu mampu mengurangi timbulan limbah yang dihasilkan dan dibuang, mengutamakan penggunaan energi terbarukan, dan mendukung efisiensi penggunaan sumber daya alam, produk yang dihasilkan, serta proses yang digunakan pada industri sehingga lebih ramah lingkungan. Namun belum banyak masyarakat memiliki pengetahuan terkait hal tersebut. Kegiatan pengabdian masyarakat ini bertujuan agar nantinya masyarakat di Desa Kesongo, Kecamatan Tuntang, Kabupaten Semarang memiliki pengetahuan dan memiliki keterampilan dalam mengaplikasikan ekonomi sirkular melalui pemanfaatan kotoran ayam dan sampah organik sebagai bahan baku pembuatan produk yang memiliki nilai tambah, yaitu pupuk kompos. Kegiatan serupa juga dilakukan di Yayasan Perklis Semarang dengan harapan masyarakat yang teredukasi semakin banyak. Berdasarkan hasil pengujian dari Laboratorium BBTPPI Provinsi Jawa Tengah, bahwa pupuk kompos yang dibuat dari kotoran ayam dan sampah organik telah memenuhi standar kuallitas kompos SNI 19-7030-2004 dan bernilai jual sebagai pupuk kompos yang bersertifikat BBTPPI Provinsi Jawa Tengah. Penerapan program ini juga dilakukan oleh masyarakat secara berkelanjutan dengan melakukan pengomposan secara rutin dan memanfatkan produk yang diperoleh sebagai pupuk organik untuk berbagai jenis tanaman. Manfaat yang diperoleh adalah tanaman yang diberi pupuk kompos dapat tumbuh dengan subur dan limbah organik yang diolah dapat menciptakan lingkungan yang lebih bersih dan sehat bagi masyarakat sekitar.  Kata kunci : pupuk kompos, sampah organik, kotoran ayam, probiotik, komposter
