Abstract

Excessive use of electricity produces emissions, as well as carbon will have impact on global warming because electricity mostly still using fossil-based energy. Usage of other alternative energy is beneficial to reduce dependence on the use of fossil fuels. Researchers are currently working to reduce the use of fossil energy by using renewable energy. Among the most common alternative energies found is water, so this research focuses on designing dry cell type HHO (Hydrogen Hydrogen Oxygen) Generator technology with hydrogen gas water electrolysis. The HHO generator functions to break water (H2O) into hydrogen atoms and oxygen atoms, known as HHO. Electrolysis testing using NaCl and a storage tube to see the rise and fall of water from the gas produced. NaCl used weighing 20 grams, 50 grams, 75 grams, and 100 grams dissolved in 500 cc of water. The results of the data obtained, many uses of NaCl produce hydrogen gas faster, the data shows 100 grams of NaCl at 180-210 seconds produces a gas volume of 175 CC compared to 20 grams produces a gas volume of 75 CC, 50 grams produces 125 CC, and 75 grams produces 150 CC

Abstract

Fly ash catalyst that has been activated using NaoH 2M was analyzed using XRD at an angle of 2θ = 15 ° - 80 ° with a wavelength (λ) of X rays of 0.15406 nm. From the results of the analysis, the NaO26Si6Y9 compound is obtained with a hexagonal structure. Furthermore, the XRD analysis results obtained in the form of wavelength, intensity, 2θ and FWHM values will be substituted into the Debye Scherrer equation to calculate the size of the crystal structure of the Fly Ash catalyst. From this equation, a graph of the relationship between ln(b) dan ln(1/cos(q ))  will be drawn so that the intercept value is - 4.0688 and the value of K = 0.9 and λ = 0.15406 nm. The value of K and λ can be calculated using the modified Debye Scherrer equation, so that the crystal size (D) is 8,10942 nm.

Abstract

Biobriquette can be used to anticipate the high fossil fuel needed as alternative fuel, cheap and easily obtained. Biobriquette is solid fuel and derived from organic residues. Generally, coal biobriquette making process used biomass waste such as straws, sawdust or various shell biomasses (coffee, cocoa, hazelnut, corn, cassava and jatropha waste). In this research used biomass waste from rice straw with adding the various coconut shell compositions. The compositions of rice straw: coconut shell are 50% : 50 %, 60%: 40%, 70% : 30%, 80% : 20%, 90% : 10% with 10 % tapioca adhesive addition. One of variables determined the biobriquette quality was pollution level generated in the combustion process which was Nox and CO gas. In this research obtained best quality composition of rice straw : coconut shell was 50% : 50% and had emission level for Nox gas at 3.17 mg/m3 and CO gas at 0.5 mg/m3. The biobriquette product was feasible due to the emission value were below the emission standards set for Nox ≤ 1000 mg/m3 and CO ≤ 500 mg/m3.

Abstract

Underground Coal Gasification (UCG) is a process of converting coal in the ground into synthetic gas that has economic value. In the UCG process which will be carried out in the UCG prototype assisted by the presence of oxygen as a gasification agent, which this gasification agent will help the process of burning coal in the ground. The flow rate of oxygen in the process of UCG affecting the coal combustion temperature and effective flame from burning coal. The highest temperature at a flow rate of 5 l/min is 240oC, at an oxygen flow rate of 3 l/min the highest temperature is 143oC and at an oxygen flow rate of 2 l/min the highest temperature is 135oC and time effective flame at a flow rate of 5 l / min ie 80 minutes, effective burning time on the speed of the flow rate of 3 l / min ie for 120 minutes and time effective flame at a flow rate of 2 l / min ie for 165 minutes. This study proves that the greater the oxygen flow rate is used as the gasification agent at UCG process the lignite coal combustion temperatures will be high and effective flame coal combustion process will be more brief.

Abstract

Underground Coal Gasification (UCG) is the process of converting the materials used to make synthetic gas in a feasible and economically attractive manner as a method for harnessing energy from underground coal sources. Coal gasification will produce a gas producer in the form of synthetic gas (syngas) with the main components consisting of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and nitrogen (N2) and low pollutants. The highest temperature produced with MT 47 lignite coal using an oxygen velocity of 5 liters/minute was 2400 C at the 35th minute, while the lowest temperature was 950 C at the 95th minute. For Subbituminous AL 51 coal using an oxygen velocity of 5 liters/minute, the highest temperature is 3540 C at 75 minutes, while the lowest temperature is 1060 C at 130 minutes. At an oxygen velocity of 5 liters/minute the flash point / burn test is on the MT 47 lignite coal type in the 10th minute and at a temperature of 1700 C. Meanwhile, the AL 51 subbituminous coal type is in the 30th minute and at a temperature of 3130 C. Based on the discussion and analysis of data from the gasification test of lignite and subbituminous coal with variations in oxygen velocity of 5 liters/minute, the results obtained are that lignite coal burns faster (burn test) in the 10th minute at a temperature of 1700 C, in the subbituminous type it has higher temperature 3130 C and longer burn test at 30 minutes.

Tandan kosong kelapa sawit (TKKS) merupakan limbah padatan yang dihasilkan dari proses pembuatan minyak kelapa sawit yang selulosa (45,95%), kadar abu (1,23%), hemiselulosa (22,84%), kadar air (3,74%) dan lignin (16,49%). Pelepah pisang mempunyai kandungan selulosa yang tinggi akan tetapi belum dimanfaatkan secara optimal yang memiliki kandungan densitas ( 1,35 gr/cm3), selulosa (63 -64 %), hemiselulosa (20 %), lignin (5%), kekuatan Tarik rata-rata (600 Mpa), modulus tarik rata-rata (17,85 Gpa), pertambahan panjang (3,36 %), diameter serat (5,8 µm), serta panjang serat (30,9240 cm). Namun bahan-bahan ini mempunyai karakteristik dan sifat fisika kimia yang berbeda-beda. Karakteristik menjadikan perlunya analisa agar menghasilkan pulp yang diinginkan berada pada kondisi optimal. Beberapa parameter yang diukur di antaranya, konsentrasi larutan NaOH dengan variasi 7% dan 9%, dengan variasi bahan baku 40-60% serta waktu pemasakan dengan variasi waktu 75, 90, 105, 120 dan 135 menit. Sehingga pada penelitian ini didapatkan kondisi optimumnya yakni pada rasio 40:60, dengan konsentrasi 9% dan waktu pemasakan selama 120 menit didapatkan nilai kadar lignin 11,21% dan kadar selulosa 68,94%. Oil palm empty fruit bunches or TKKS are solid wastes produced from the process of making palm oil which are cellulose (45.95%), ash content (1.23%), hemicellulose (22.84%), water content (3.74 %) and lignin (16.49%). Banana midrib has a high cellulose content but has not been used optimally which contains density (1.35 g/cm3), cellulose (63 -64 %), hemicellulose (20 %), lignin (5%), average tensile strength. average (600 Mpa), average tensile modulus (17.85 Gpa), increase in length (3.36%), fiber diameter (5.8 m), and fiber length (30,9240 cm). However, these materials have different physicochemical characteristics and properties. The characteristics make the need for analysis in order to produce the desired pulp in optimal conditions. Several parameters were measured including the concentration of NaOH solution with variations of 7% and 9%, with variations of raw materials 40-60% and cooking time with variations of 75, 90, 105, 120 and 135 minutes. So that in this study the optimum conditions were obtained, namely at a ratio of 40:60, with a concentration of 9% and cooking time for 120 minutes, the lignin content was 11.21% and the cellulose content was 68.94%.
