Pemisahan partikel-partikel tersebut dari umumnya dilakukan dengan menggunakan siklon. Konstruksi dan kondisi operasi siklon, seperti suhu gas yang masuk, berperan penting dalam menentukan kinerja pemisahan partikel dari gas tersebut. Penelitian ini bertujuan untuk mengkaji pengaruh perubahan suhu gas terhadap kinerja siklon dalam memisahkan partikulat dan tar dari gas-gas hasil gasifikasi tandan kosong kelapa sawit. Hasil kajian menunjukkan bahwa peningkatan suhu gas yang masuk ke siklon mampu memisahkan partikel berukuran 5â€“6 Î¼m di kisaran suhu 200â€“300 Â°C pada efisiensi minimum 50%. Hasil perhitungan efisiensi pengumpulan rata-rata mencapai 98,23%, sedangkan hasil pengukuran adalah 85,56%. Hasil perhitungan dan ekperimen terhadap tekanan jatuh pada siklon, masing-masing, adalah 100,11 dan 87 mmH2 O, berada pada kisaran standar tekanan jatuh yang disarankan. Efisiensi dan tekanan jatuh yang diperoleh menunjukkan bahwa siklon dapat bekerja dengan baik.

A cyclone is usually used in the purification process to separate particles and tarss from the gas. Particle separating performance of a cyclone is affected by its construction and operating conditions, such as temperature of the entering gas. The objectives of this study is to examine the effect of the entering gas temperature to the cyclone performance in separating particulates and tar from gases produced by gasification of oil palm empty fruit bunch. The results shows that the cyclone was capable in separating particles with size of 5-6 Î¼m at entering gas temperature range of 200- 300 Â°C, at a minimum efficiency of 50%. The calculated average collection efficiency was 98.23% while the experimental results were 84.56%. Calculation and experimental data on pressure drop within the cylone was 100.11 and 97.0 mmH2 O, respectively, and fall within the required standard pressure drop. The collection efficiency and pressure drop indicated that the cyclone performed well. The study also suggests that cyclone is best to be used at the first row of the purification system for gases produced by gasification of empty fruit bunch since the temperature is still high enoughÂ Keywords : Collection Efficiency; Diameter Cut Size; Pressures Drop; Temperature of Gas; TarÂ

Proses pengolahan ikan patin di Indonesia memiliki hasil samping hingga 67% dari total bobotnya dan berpotensi menimbulkan polusi. Pemanfaatan hasil samping sebagai biopelumas yang ramah lingkungan merupakan salah satu solusi dalam penanggulangan hasil samping menjadi produk yang bernilai ekonomis. Namun, pelumas yang dihasilkan harus dapat memenuhi standar nasional Indonesia (SNI). Riset ini bertujuan untuk melakukan karakterisasi biopelumas yang dibuat dari hasil samping produksi ikan patin Siam (Pangasius hypophthalmus), berupa bagian jeroan atau isi perut, dan membandingkannya dengan SNI 7069.9:2016. Isi perut patin diekstrak menjadi minyak kasar dengan metode wet rendering. Selanjutnya, minyak kasar diubah menjadi biopelumas melalui tahapan hidrolisis, polimerisasi, dan poliesterifikasi. Bahan baku minyak kasar diuji komposisi asam lemak, bilangan asam lemak bebas, dan bilangan penyabunan. Sementara itu, karakterisasi biopelumas dilakukan dengan variabel densitas, viskositas kinematik pada suhu 40 dan 100Â°C, warna, indeks viskositas, flashpoint, pour point, dan uji korosi. Hasil penelitian memperlihatkan bahwa suhu poliesterifikasi 135Â°C akan menghasilkan biopelumas terbaik. Biopelumas ini memiliki densitas 0,903 g/cm3; viskositas 40Â°C sebesar 39,76 cSt; viskositas 100Â°C sebesar 7,94 cSt; indeks viskositas 176; dan sifat korosi yang rendah (1A). Indeks viskositas dan korosi bilah tembaga menunjukkan bahwa minyak patin adalah bahan baku biopelumas yang potensial. Namun, titik nyala dari biopelumas masih rendah (127Â°C) dan titik tuangnya juga tinggi (27Â°C). Modifikasi proses lebih lanjut dapat dilakukan untuk menaikkan titik nyala serta menurunkan titik tuang, sehingga produk ini dapat memenuhi persyaratan sebagai biopelumas.ABSTRACTThe pangasius processing in Indonesia has a by-products waste, that can reach up to 67% of its total weight, and may cause pollution. An environmentally friendly lubricant (biolubricant) is a potential solution that transforms the by-products waste into an economically value product. However, the proceed biolubricant has to meet the Indonesian National Standard (abbreviated SNI). The purpose of this study were to characterize the biolubricant from pangasius (Pangasius hypophthalmus) by-products, which is the viscera part, and to compare the product with the Indonesian lubricant standard SNI 7069.9: 2016 reference. The crude fish oil was extracted from the viscera using the wet rendering method. Furthermore, the crude fish oil was converted into biolubricant through the stages of hydrolysis, polymerization, and polyesterification. The raw material of pangasius by-products was characterized by fatty acid profiles, free fatty acid numbers, and saponification numbers. Meanwhile, the biolubricant product was characterized by density, kinematic viscosity at temperatures of 40 and 100Â°C, color, viscosity index, flashpoint, pour point, and hazardous corrosion test. The results showed that the best biolubricants were those through the polyesterification temperature process of 135Â°C. This biolubricant has a density of 0.903 g/cm3; a viscosity at 40Â°C of 39.76 cSt; a viscosity at 100Â°C of 7.94 cSt; a viscosity index of 176; and low corrosion level (1A). The viscosity index and corrosion of copper blades were adequate for biolubricant standards. However, the biolubricant flashpoint was relatively low (127Â°C) and the pour point was relatively high (27Â°C). A further modification is needed to adjust the flash and pour points so that the biolubricant able to fullfil the national lubricant standard.

Energy consumption in non-catalytic biodiesel production is still high, and needs to be reduced to the optimum level. It can be accomplished by recirculating the heat being used in the process by using heat exchanger. The objective of this study is to analyze the energy ratio of the system as influenced by the heat recirculation through a heat exchanger. This experiment used a superheated methanol vapor method for non-catalytic biodiesel production. The study was started with the determination and calculation of physical and thermal properties of materials to be used (palm olein, methanol, and methyl ester), continued with the designing of the heat exchanger, the experiment itself, and the energy ratio analysis. The process was occured in semi-batch mode with 3 levels of methanol flow rate, i.e., 1.5, 3.0, and 4.5 mL/minute, at reaction temperature of 290 °C. The results show that heat recirculation by using heat exchanger can increase the energy ratio from 0.84 to 1.03, according to the definition that energy ratio is the ratio between energy content of the biodiesel to the total energi of the feedstock and the process energy. If the energy ratio is defined as the ratio between the increase in energy content of the biodiesel from its feedstock to the process energy, the energy ratio was found to be 7.85, 2.98, and 2.87 for the respective methanol flow rate of 1.5, 3.0, and 4.5 mL/min.

Application of static mixer is expected to enhance yield of biodiesel production and reduce catalyst requirement. Static mixer could increase the mixing effectiveness of oil and methanol, so that FAME yielded at the reactor would increase and could reach the desired level of conversion with lower catalyst requirement.A more in-depth study of the mixing and its relation to the effectiveness of transesterification reactions is indispensable to obtain important parameters which is necessary in process improvement and reactor design. The objective of this study was to examine the flow profile and its relation on mixing of oil and methanol in a continuous type reactor using computational fluid dynamics (CFD). Simulation was conducted using five scenarios of mass flow rate in the range of 5-20 L/min for oil and 0.6-2.4 L/min for methanol. It was observed that the static mixer elements can increase the uniformity of vorticity, which indicates that the flow is not only moved on the mainstream (axial direction) but also moves toward the y-axis and the z-axis randomly as well as rotational motion. The uniformity of vorticity along the static mixing reactor provided a better chance of mixing and increase the possibility of reactions between molecules of reactant. Keywords : biodiesel, transesterification, static mixer, computational fluid dynamics (CFD), vorticity

The sustainability of hydrogen as an energy carrier depends on the production process and the source of raw materials. The choice of substrate in anaerobic digestion process plays an important role to maximize biohydrogen production because it depends on its availability and the composition of substrate. The purpose of this study is to design and construct a prototype reactor for biohydrogen production and to determine the potential of H2 gas production from anaerobic digestion process. This study uses an experimental research method with three operating temperature variations in the reactor, at the range of thermophilic temperatures, i.e. 55°C, 60°C, and 65°C. The substrate used was POME and cow dung, and the process was conducted in 24 hours which is assumed to be the stage of non-methanogenic within the anaerobic process. From this research, the prototype of continuous stirred tank reactor (CSTR) in batch system was made from acrylic, with a capacity of 6 liters biomass waste. Using the reactor, total biohydrogen gas produced during 24 hours process with cow manure as substrate was 0,0932 gram at 55°C; 0,0307 gram at 60°C and 0,0797 gram at 65°C. While, biohydrogen production using POME as substrate was 0,0645 gram at 55°C; 0,1708 gram at 60°C, and 0,0636 gram at 65°C. These results indicate the potentiality of POME and cow manure to produce biohydrogen gas during anaerobic digestion process.

Java turmeric (Curcuma xanthorrhiza Roxb.) is a medicinal plant used as raw material for making herbal medicine, its rhizome cut into slices and dried so called simplicia. Curcuma has a harvest moisture content is high enough to need a great energy for drying. Generally, the theory used to analyze the energy efficiency is the first law of thermodynamics that describes the principle of conservation of energy. However, this theory has limitations in measuring the loss of energy quality. To determine whether the energy used in the drying process has been used optimally in terms of quality, the second law of thermodynamics -known as exergy analysis- is used. The purpose of this study is to determine the efficiency of the thin layer drying of curcuma slices with exergy analysis. The results show that the process conditions affect the energy utilization ratio and exergy efficiency of drying. Exergy analysis method based on the second law of thermodynamics has been used to determine the amount of exergy destroyed so that the efficiency of the drying process can be determined more accurately. Exergy efficiency varies between 96.5%-100% for temperatures of 50 °C to 70 °C at 40% RH and 82.3% - 100% for 20% to 40% RH at 50 °C.ABSTRAKTemulawak (Curcuma xanthorrhiza Roxb.) merupakan tanaman obat yang simplisianya digunakan sebagai bahan baku pembuatan jamu atau obat tradisional. Pengeringan merupakan proses utama dalam memproduksi simplisia. Untuk menganalisis efisiensi energi suatu proses pengeringan umumnya digunakan hukum termodinamika pertama yang menjelaskan tentang prinsip kekekalan energi. Akan tetapi teori ini mempunyai keterbatasan dalam mengukur penurunan kualitas energi. Untuk mengetahui apakah energi yang digunakan pada proses pengeringan sudah digunakan secara optimal dari sisi kualitas, digunakan hukum termodinamika kedua atau yang dikenal dengan analisis eksergi. Tujuan penelitian ini adalah menentukan efisiensi proses pengeringan lapisan tipis irisan temulawak dengan metode analisis energi dan eksergi. Dalam studi ini, metode analisis energi dan eksergi berdasarkan hukum termodinamika pertama dan kedua telah digunakan untuk menghitung rasio penggunaan energi dan besaran eksergi yang musnah (exergy loss). sehingga efisiensi proses pengeringan irisan temulawak dapat ditentukan secara akurat. Hasil penelitian menunjukkan bahwa kondisi proses pengeringan mempengaruhi rasio penggunaan energi dan efisiensi eksergi pengeringan. Semakin tinggi suhu dan RH pengeringan maka rasio penggunaan energi semakin rendah dan efisiensi eksergi semakin tinggi. Efisiensi eksergi pengeringan temulawak bervariasi antara 96,5%-100% untuk selang suhu 50 oC hingga 70 oC pada RH 40% serta 82,3% - 100% untuk selang RH 20% hingga 40% pada suhu 50 oC.

AbstractEmpty fruit bunch (EFB) and shell of oil palm are potential sources of bioenergy because they contain lignocellulose (cellulose, hemycellulose and lignin) which can be converted to bio-oil (liquid), char, or combustible gases by pyrolysis process. Operating temperature of the pyrolysis process will influence the composition of the liquid, char and gases, as well as its characteristics. The objective of this study is to characterize the pyrolysis product of both empty fruit bunch and shell as affected by the pyrolysis temperature. The experiment was conducted by using a lab scale pyrolysis reactor, specially designed with controlable temperature. The temperature of the pyrolysis process was controled at 300°C, 400°C, 500°C, and 600°C level, and the product was measured and analysed. The result showed that pyrolysis of shell produced char, liquid and gases at the range of 34.99 - 63.78%, 22.76 - 43.28% and 13.47 - 21.73%, in mass fraction respectively. While pyrolysis of empty fruit bunch produced char, liquid and gases at the range of 30.66 - 64.7%, 16.25 - 29.16% and 18.98 - 44.49%, in mass fraction respectively. Increasing temperature resulted in increasing calorific value of the pyrolysis char from shell and empty fruit bunch in range of 25.64 – 29.60 kJ/g and 24.50 – 27.86 kJ/g, respectively. However, the calorific value of pyrolysis gases was decreasing with the increasing temperature in range of 12.18 kJ/g – 20.05 kJ/g and 11.98 kJ/g – 15.94 kJ/g, respectively. The gas calorific value did not account H2 gas, which might be the cause of the phenomenon. Shell pyrolysis temperature increasing caused the increasing of CO concentration in range 2.86% - 18.42% while the CH4 concentration increased at 400°C level afterwards decreased at higher temperature level in range of 0.89% - 2.84%. The increasing of EFB pyrolysis temperature increased CO dan CH4 concentration in range 3.8% - 15.74% and 0.29% - 0.76%, respectively.AbstrakCangkang dan tandan kosong kelapa sawit (TKKS) merupakan sumber bioenergi yang potensial karena mengandung lignoselulosa (selulosa, hemiselulosa dan lignin) sehingga dapat dikonversi menjadi cairan, arang atau gas mampu bakar melalui proses pirolisis. Suhu pengoperasian pada proses pirolisis akan mempengaruhi komposisi cairan, arang dan gas serta karakteristik hasil pirolisis tersebut. Tujuan dari penelitian ini adalah untuk mengkarakterisasi produk pirolisis cangkang dan tandan kelapa sawit yang dipengaruhi oleh suhu pirolisis. Penelitian dilakukan dengan menggunakan reaktor pirolisis skala lab, yang didesain khusus agar suhunya dapat dikendalikan. Suhu pirolisis dikendalikan pada level 300°C, 400°C, 500°C dan 600°C, kemudian hasil pirolisis diukur dan dianalisa. Hasil penelitian menunjukkan bahwa pirolisis cangkang menghasilkan fraksi massa arang , cairan dan gas dalam rentang 34.99 - 63.78%, 22.76 - 43.28% dan 13.47 - 21.73% secara berturut-turut. Sedangkan pirolisis TKKS menghasilkan fraksi massa arang, cairan dan gas dalam rentang 30.66 – 64.76%, 16.25 – 29.16% dan 18.98 – 44.49% secara berturut-turut. Peningkatan suhu menghasilkan peningkatan nilai kalor arang hasil pirolisis cangkang dan TKKS dengan rentang antara 25.64 – 29.60 kJ/g dan 24.50 – 27.86 kJ/g. Tetapi, nilai kalor gas pirolisis menurun seiring dengan peningkatan suhu pirolisis dengan rentang 12.18 kJ/g – 20.05 kJ/g dan 11.98 kJ/g – 15.94 kJ/g untuk pirolisis cangkang dan TKKS. Nilai kalor gas tidak menghitung gas H2 yang mungkin menyebabkan fenomena tersebut. Peningkatan suhu pirolisis cangkang kelapa sawit mengakibatkan peningkatan konsentrasi gas CO pada rentang 2.8% - 18.42% sementara konsentrasi gas CH4 meningkat pada suhu 400°C namun menurun kembali dengan rentang 0.89% - 2.84%. Peningkatan suhu pirolisis TKKS meningkatkan konsentrasi gas CO dan CH4 pada rentang 3.81% - 15.74% dan 0.29% - 0.76%.
