Abstract

The use of renewable energy for rural electrification in Indonesia has great potential, including the potential for energy from biomass. One way to convert biomass into renewable energy is through the pyrolysis process. Heating technology in pyrolysis is currently under development, one of which uses electrical energy with induction heating technology. Therefore, the aim of this research is to design a pyrolysis tool with a suitable induction heater, where this tool is powered by an electrical energy source. The pyrolysis tool is designed to use an induction heater that is varied by using a three-coil and a seven-coil heating element. The pyrolysis tool design was then realised in prototype form with a length of 1500 mm, width of 1000 mm and height of 1400 mm. Prototype testing was carried out using one heater, with each coil variation operated until the pyrolysis reactor reached the design temperature of 500°C within 120 minutes. The test results of the prototype pyrolysis unit using an induction heater with a three-coil heating element showed that the reactor temperature could not reach the desired target, but only reached a temperature of about 305.6°C in 120 minutes, with the electrical energy required for one test being about 5 kWh. Meanwhile, tests using an induction heater with a seven-coil heating element showed that the reactor temperature target of 500°C in 120 minutes could be well achieved. The electrical energy required for a test using a seven-coil heater is approximately 8 kWh.

Abstract

Honeycomb is applied to the Open Series Subsonic Wind Tunnel which aims to obtain a unidirectional fluid flow shape with uniform (laminar) and stable fluid flow velocities. Honeycomb testing was carried out experimentally at a flow velocity of 3 m / s without honeycomb using a variety of shapes: hexagonal, square, and circular. Each honeycomb shaped to 8mm diameter. The results of the analysis on honeycomb testing with variations in shape obtained the value of turbulence intensity that occurs in the test section, namely for hexagonal shape variations the flow that occurs is better than circular shape, while in circular shape variations the value of turbulence intensity is better than square shape. The results of the Reynold's number calculation show that the flow that occurs is laminar with the following values, in the hexagonal shape variation the value is 787, circular shape 956.48, and square shape 1199.42. After calculating the turbulence intensity and Reynold's number, we can conclude that honeycomb with hexagonal shape variation is optimal than circular shape, and circular is optimal than square.

Abstract

Currently the government is working to achieve a Golden Indonesia 2045 and Indonesia Net Zero Emissions (NZE) 2060. In an effort to reduce carbon emissions, one of the government's efforts is to use electric vehicles in the transportation sector and create an Energy Saving Car (KMHE) competition organized by Ministry of Education, Culture, Research and Technology (Kemendikbudristek). This research was conducted to determine the aerodynamic values and their influence on variations in the frontal area and leading edge of the Pase Team Electric car body at Malikussaleh University. This simulation analysis was carried out using the computational fluid dynamic (CFD) method using Ansys Fluent software as a simulation tool. With variations in air flow speed of 2.7 m/s, 5.5 m/s, 8.3 m/s and 11.1 m/s, the aerodynamic values and influences on each body variation are obtained. For the drag coefficient on a body with a frontal area A=0.48m2, the average value obtained from the three leading edge angles 36áµ’, 15áµ’ and 0áµ’ is 0.151. Then for the lift coefficient, an average value of -0.255 is obtained, which means the body produces a relatively low CD but produces large downforce. For the drag coefficient on a body with a frontal area A=0.39m2, the average value obtained from the three leading edge angles 36áµ’, 15áµ’ and 0áµ’ is 0.134. Then for the lift coefficient, the average value was -0.138. So it can be concluded that by reducing the frontal area on the body and the leading edge angle, the Cd value can be reduced by 11.34% and CL by -46%.

Abstract

Pyrolysis is a commonly used method to produce main products such as bio-char, bio-oil and syngas. However, the practical use of syngas as a fuel is currently constrained by suboptimal properties and the necessity for specialized storage. This study investigated the impact of using syngas directly as an additional fuel for heating the pyrolysis reactor on process parameters and the properties of the resulting bio-char products. The experiment was conducted using two process variations: (i) pyrolysis utilizing syngas as fuel for co-firing with LPG, and (ii) pyrolysis using only LPG as fuel. The variables observed during the testing included the consumption of LPG fuel, process time, heating rate, pyrolysis product yields, and the properties of the bio-char. Characterization of the bio-char was carried out through proximate analysis, bomb calorimetry, thermogravimetric and FTIR analysis. Based on the experimental results it can be concluded that co-firing is able to save on the use of LPG and reduce process time. In terms of product yield, there was no significant difference when syngas was co-fired with LPG. In terms of the properties of the bio-char product, syngas co-firing pyrolysis helps in reducing the moisture content, increasing the fixed carbon content, and also increasing the calorific value up to 26855 J/g.

Abstract

Limbah biomassa dapat menimbulkan pencemaran lingkungan, munculnya penyakit dan menurunkan nilai estetika (keindahan) kota serta masalah-masalah lainnya. Hal ini terus mendorong manusia untuk melakukan inovasi untuk mendapatkan sumber energi baru terbarukan dengan memanfaatkan limbah-limbah dari alam yang kurang dimanfaatkan seperti limbah kelapa muda. Penelitian ini bertujuan untuk mengkaji karakteristik biopelet yang diproduksi dari limbah kelapa muda dengan metode torefaksi pada suhu 300ËšC. Produk hasil torefaksi berupa bio-arang torefaksi selanjutnya dihaluskan dan diayak hingga ukuran partikel 20 mesh dan 40 mesh sesuai variasi nya, kemudian dicampurkan dengan perekat yang divariaskan  sebesar 5%, 10% dan 15%  dan diaduk secara manual hingga homogen selanjutnya dicetak menjadi biopelet. Dari pengujian yang telah dilakukan, diperoleh persentase moisture terendah sebesar 7,28% pada biopelet dengan sampel M40P5%, dan fixed carbon tertinggi sebesar 49,82% pada biopelet dengan sampel M40P5%. Laju pembakaran paling optimal dan nilai kalor tertinggi diperoleh sebesar 0,421 g/min dan 6586,58 kcal/kg pada biopelet dengan sampel M40P5%.  Hasil penelitian ini menunjukkan bahwa variasi perekat semakin banyak  memberikan pengaruh penurunan terhadap nilai kalor, moisture dan  fixed carbon  dan laju pembakaran tetapi sebaliknya pada ukuran mesh semakin tinggi memberikan kenaikan. Keywords: Biomassa, nilai kalor, kadar air, perekat, mesh

Abstract

The research in this final project discusses the economic calculation of electrical energy consumption in a 220 VAC system at a residential load on a type 54 house. The simulation of the AC system is carried out with ETAP 12.6 software. Simulation is done by making installations with residential loads with cables that have a length according to the distance to the loads. From the ETAP simulation, it can be seen the current and line resistance values on the report manager display so that the losses and efficiency of the two systems can also be known. Based on the results of simulations and calculations, the total value of the losses that occur in the 220 VAC system is so small that it looks like 0 watts, this happens because the simulation results are shown in kWatt in the ETAP.

Abstract

The production of bioethanol from non-plant lignocellulosic materials has reached a commercial scale and is advocated as a possible solution for the decarbonization of the transport sector. Porang pulp tubers can be converted into bioethanol because they have abundant potential due to their high glucomannan content. The purpose of this study was to determine the effect of fermentation time and the ratio of yeast addition on bioethanol production. The methods used are hydrolysis, fermentation and distillation methods. The hydrolysis process used 5% (v/v) HCl catalyst, the fermentation process with 6 gr sample powder tuber of waste used Saccharomyces cerevisiae bacteria with varying ratios of 2.5, 4 and 6.5 g and variations in fermentation time for 2, 4 and 6 days at 38-40˚C. The results showed that the duration of fermentation had a significant effect on the yield of bioethanol, where microorganisms have the opportunity to break down more glucose to produce bioethanol. While the ratio of the addition of yeast added to the fermentation process, the greater the ratio of the addition of yeast, the greater the bioethanol produced. Where the addition of 6.5 grams of yeast and 6 days of fermentation time, resulted in a yield of 9.889%, a bioethanol concentration of 37.599%, a refractive index of 1.3642 and a density of 1.04 g/ml.

Abstract

Indonesia is one of the coffee-producing countries where production tends to increase from year to year. Currently, residuals from coffee-fruit processing such as coffee-skin and husks are thrown away without any use and this biomass residual contains several toxic chemicals such as alkaloids, tannins, and polyphenols. One of potential uses of coffee-industry by-product is to make activated carbon (ACs), which is made through a carbonation process and followed by an activation process. In this study, chemical activation was carried out using chemical activators ZnCl2 and NaOH. The purpose of this study is to prepare and investigate the characteristics of chemically activated coffee skin bio-char focusing on the surface properties and iodine adsorption capacity. Prior to carbon activation, a purpose built pilot-scale reactor was fabricated and tested at temperatures of 400 C and 500 C. The difference in carbonation temperature and variations in activator concentration alter the absorption properties. The results showed that the coffee-skin pyrolyzed at 500 C and activated by 2% NaOH solution exhibits the highest absorption value of 720.2 mg/g. Lower absorption values were observed in any ZnCl2 activator samples. SEM-EDS analysis result suggests significant changes in composition of the ACs before and after activation. Most of impurities are gone during activation and washing. The value of C atoms increases and the pores structure of the activated carbon are expanding showing suitable properties for adsorbent.
