Abstract

B30 is a blend of 30% biodiesel produced from the transesterification process of vegetable oils and 70% diesel derived from fossil fuels. The use of biodiesel is still facing the problems such as high particulate value, water content, and reduced filter life, so it is necessary to improve the fuel-containing biodiesel with bio-additives. This study aimed to determine the effect of bio-additive addition on the characteristics of B30, performance and exhaust emissions of diesel engines, and to determine the best formula from two types of formulas, namely bio additive A (a mixture of turpentine oil, clove terpenes, and citronella) and bio additive B (a mixture of turpentine oil, clove terpene, and rhodinol). The concentration of bio-additive used in the engine performance test was 0.1%. The experimental data was then analyzed using descriptive analysis and one-way ANOVA on the 95% level of characterization testing. The best formula was found in formula B based on the performance test analysis, which increased the torque and power values by 18.09–24.58 Nm and 3.85–5.04 KW, respectively. Furthermore, fuel consumption increased in the bio-additive A by 1,238–1,546 mL/hour and bio-additive B by 1,215 – 1,515 mL/hour. Intriguingly, the CO2 and NOx emissions values decreased by 6–17.6% and 337–1,205 ppm, respectively. Nevertheless, it was observed that the smoke number increased by 2.85 – 6, 45 FSN in bio-additive B. Keywords: B30, biodiesel, bio-additive; diesel engine; essential oil

Abstract

The raw biogas from the digester is a gas produced by bacterial fermentation which has a composition of methane (CH4), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and various other gases. Gases other than methane in raw biogas can damage the combustion system if used directly. The digester that produces biogas is used to move the generator engine using raw materials, such as cow feces, goat feces, fowl feces, straw, husks, and clean water. In the mixing process, all the raw materials are stirred or mixed evenly in the digester. Next is the process with five stages, namely (1). In the first stage: on the 11th day, adding clean water and fermentation carried out for 21 days, (2). The second stage: adding starter, hormones, charcoal flour, cow feces, fowl fees, goat feces, straw, and husks, then fermented for 7 days. (3). The third stage: adding a starter and fermenting it for 7 days. (4). Fourth stage: ready-to-use compost or solid fertilizer is ready to produce. (5). Fifth stage: liquid fertilizer is ready for production. In the gathering stage: all raw materials are stirred or mixed evenly in the digester and fermented for 1.5 months to become biogas. The last stage is the distribution of biogas: for household needs, and generators. From this research, it can conclude that the water column height (h) is 10.42 cm, and the maximum water column height is 9 cm so that the reactor is safe and the maximum pressure that can be attained is 879.1918 kg.m-1.s-2. The heating rate for ratio A is 0.0600 oC.s-1 and the heating rate for ratio B is 0.0640 oC.s-1. The calorific value produced from heating 1 liter of clean water using biogas from ratio A is 297.99315 kJ, and the calorific value of ratio B is 288.9174 kJ. With a compressor pressure of 8 psi, biogas can be inserted in this using a freon tube for a maximum of 6000 seconds with a mass of 6163 grams. In filling biogas, the biogas manometer should show the maximum number (between 16.50 – 25.50).

Abstract

The purpose of this research was to apply exploratory data analysis techniques to building energy meters, such as electricity, cold, heat, and steam meters. A thorough understanding of energy usage patterns becomes increasingly vital in an era of growing awareness of energy management and sustainability. Trends, patterns, and anomalies can be identified in building energy meter data using meticulous data exploration approaches, which can give significant insights for increasing energy efficiency. Exploratory data analysis combined with machine learning approaches may be was used to reveal hidden patterns of energy usage and examine the links between relevant factors. The findings of this exploratory data analysis gave vital insights into building energy use trends. Some significant and hidden information that was crucial for understanding energy usage within a certain time frame in each building was discovered via the investigation of the data used in this study. Steam had the highest use, whereas electricity had the lowest. Utilities were more popular before 5 a.m., followed by healthcare, with daytime use hours beginning around 10 a.m., depending on the area. During the working day, the industry needs more energy. Places of worships use more energy on weekends. There was a significant relation between the number of floors and spaces per level of a building and the height meter reading between May and October. There is a significant association between the kind of buildings used for schools, workplaces and high energy use. This study significantly contributed to the management of the energy and sustainability domains. Using exploratory data analysis and machine learning approaches to building energy meters could optimize energy usage, minimize running costs, and enhance overall energy efficiency. This research is still very open to be continued using other methods, to obtain other hidden information.

Abstract

The use of biodiesel is still experiencing problems due to large amount of water content which produce from the transesterification process, making it has unstable oxidizing properties. The large amount of water content in biodiesel causes the emergence of microorganisms which becoming sludge in the engine room, and can clog the fuel filter. In this study, we propose the application of oxygenate bio-additives to minimize water and particulate content by using turpentine essential oils, clove terpenes, rhodinol, camphor oil, and synthetic additive 2EHN. Based on the study's results, the water content of biodiesel B35 with the AC bio-additive mixture experienced the highest decrease in water content, which was 18% or 287.2 ppm and performs well in reducing particulate levels of 4, 6, and 14 microns. The completely randomized design (CRD) test results for non-factorial moisture content on days 0, 3, 5, 7, and 14 and particulate matter 4, 6, and 14 microns showed no significant difference because each P value was obtained greater than α (0.05). Keywords:   Bio-Additives, Biodiesel, Oxidation, Oxygenate, Particulates.

Abstract

Emulsi biodiesel-air dapat digunakan sebagai bahan bakar alternatif untuk pengeringan karet remah. Biodiesel yang digunakan merupakan campuran 70% solar dan 30% FAME (B30) serta campuran 60% solar dan 40% Fatty Acid Methyl Ester (FAME) (B40) dari minyak sawit mentah (CPO). Potensi penggunaan biodiesel untuk pengeringan karet remah tidak kurang dari 90-120 juta liter per tahunnya. Namun penggunaan biodiesel sebagai bahan bakar pengeringan remah karet masih perlu dikaji karena banyak mengandung NOx dan PM (partikel) yang berpotensi menurunkan kualitas karet.Penggunaan air dimaksudkan untuk ditingkatkan penghematan bahan bakar dan meminimalkan emisi Nitrogen Oksida (NOx) dan partikel udara yang berpotensi menurunkan kualitas karet. Berdasarkan beberapa penelitian terdahulu untuk membuat emulsi minyak-air solar dengan menggunakan surfaktan, maka pada penelitian ini dikembangkan metode preparasi emulsi biodiesel B30-air dan emulsi biodiesel B40-air dengan menggunakan campuran surfaktan Span 80 dan Tween 80, dengan rasio antara biodiesel dan air yaitu 90:10 (v/v). Emulsi biodiesel-air yang homogen dan stabil yaitu emulsi B30-air dan B40-air diperoleh dengan menambahkan emulsifier 5% yang terdiri dari campuran Span 80 dan Tween 80 sebagai surfaktan sehingga membentuk emulsi B30-air dan B40-air. Hasil penelitian menunjukkan bahwa Biodiesel B30-emulsi air dan emulsi B40-air dengan kadar air 10% dapat disintesis menggunakan kombinasi surfaktan SPAN 80 dan TWEEN 80 sebanyak 5% dengan cara diaduk menggunakan mixer kecepatan tinggi (23.000 rpm) selama 1-2 menit hingga menghasilkan emulsi yang stabil lebih dari 30 hari (untuk emulsi air B30) dan sampai dengan 5 hari (untuk emulsi air B40) untuk pengeringan 130 - 135ºC. Untuk emulsi B30-air dan B40-air dengan kadar air 10% layak digunakan sebagai bahan bakar alternatif pengeringan karet remah. Kualitas karet remah kering yang dihasilkan memenuhi standar persyaratan sesuai SNI 1903:2017.

Abstract

Piperonal as a precursor of cancer drug (Curcumin analogues) can be synthesized from extract of lawang’s bark (Cinnamomum culilawan Blume) with multiple stages, among others: isolation of essential oils, isolation safrole, safrole isomerization, and synthesis of piperonal. Essential oils were isolated from the bark of lawang (the water content of 46.2%) using a water distillation system with 1/3 volume of high boiler for five hours. Isolation of safrole from lawang bark oils was performed using NaOH solution and purified using reduced pressure distillation system at a temperature of 90-123°C / 1 mmHg. The safrole isomerization was undergone using alkali catalyst (KOH) without solvent at a temperature of 120°C for 8 hours. Oxidation of isosafrol was performed using KMnO in acidic conditions using a KTF 4 tween 80 at a temperature below 30°C, and purified using silica gel. Results of isolation yield 0.94% with 14 components were determined through GC-MS, including 67.35% eugenol, safrole 13.96%, 12.61% methyl eugenol, 4-terpineol sineol 1.79% and 1.55%. The isolated safrole yield of 17.21% with purity testing and identification using FTIR, HNMR and GCMS confirmed the product was safrole. The isomerization obtained yield of 77.56% with GC analysis indicated compounds of cis-isosafrole and trans-isosafrole. The results of oxidation obtained yield of 65.63% with a purity of 100% by GCMS and the H-NMR indicated the product is piperonal.
