Abstract

The development of biodiesel in Indonesia began in 2006, and by 2023 it had reached the B35 blend, aiming to reduce carbon emissions and enhance energy security. This study utilizes used cooking oil as a feedstock for biodiesel and blood cockle shells as the catalyst source, with the goal of reducing household waste. The objective of this research is to investigate the effect of catalyst concentration from blood cockle shells impregnated with NaOH on the yield and quality of biodiesel. The research method began with the preparation of CaO catalyst through NaOH impregnation, characterized using XRF, and then applied in the transesterification process using a Simple Stirred Tank Batch Reactor with variations in catalyst concentration (3%, 3.5%, 4%, 4.5%, and 5%) and temperature (50°C and 60°C). XRF characterization results showed an increase in CaO content from 79.0910% before to 89.2466% after impregnation. Based on the analysis data, the best conditions were achieved at 5% catalyst concentration and 60°C, resulting in a yield of 83.6%, with a density of 0.8700 g/mL, a viscosity of 4.6523 mm²/s, a flash point of 151°C, and a cetane number of 73.4 — all of which meet the SNI 7182-2015 standard. The methyl ester content analyzed using GC-MS on the optimum sample showed that the dominant compounds was methyl palmitate with a total area of 42.84% and methyl oleate with 37.09%. Keywords :    Biodiesel, CaO Catalyst, Transesterification, Used Cooking OilABSTRAKPengembangan biodiesel di Indonesia mulai sejak 2006 dan pada tahun 2023 sudah mencapai campuran B35, bertujuan untuk mengurangi emisi karbon dan meningkatkan ketahanan energi.

Abstract

The Jambi Province has smallholder plantations established on peatlands, one of which is the local Betara variety of areca palm (pinang), known for its adaptability to high peat water table (TMAT) conditions. However, drainage remains necessary to prevent waterlogging. Peat decomposition releases carbon emissions, including dissolved organic carbon (DOC) into drainage water. The IPCC emphasizes the need for scientific data on carbon loss through DOC from tropical peatlands. This study was conducted in a Betara areca palm plantation located in Catur Rahayu Village, Dendang Subdistrict, Jambi, aiming to obtain quantitative data on DOC concentration in peatland drainage. TMAT observations and water sampling were carried out in a 100x100 m plot during the rainy season, coinciding with flooding in nearby areas. The results showed that the lowest TMAT reached -50 cm, consistently recorded at 20 observation points, indicating peat vulnerability even during the rainy season. No correlation was found between peat depth and TMAT. Groundwater from the peat flowed into a nearby tertiary canal connected to a secondary canal. The average DOC concentration at TMAT monitoring points was 3.321 mg/L, and in the tertiary canal, it was 3.309 mg/L. Keywords: Carbon; DOC; Drainage; IPCC; TMAT.ABSTRAKProvinsi Jambi memiliki perkebunan rakyat di lahan gambut, salah satunya adalah kebun pinang varietas lokal Betara yang adaptif terhadap kondisi tinggi muka air tanah (TMAT) gambut.

Abstract

Noise is one of the important risk factors in the workplace that is often overlooked, particularly in small-scale furniture enterprises that have limitations in controlling the work environment. High noise exposure has the potential to cause hearing disorders as well as non-audiological complaints that impact worker productivity. This study aimed to analyze noise levels using a multi-level approach at the sound source, workers, supporting areas, and surrounding environment, and to examine their relevance to worker characteristics. The study was conducted in furniture enterprises in Tanjungpinang City with a quantitative descriptive design, using direct noise measurements in accordance with the Ministry of Manpower Regulation No. 5 of 2018 and a worker characteristics questionnaire. The findings showed that 78% of workers were exposed to noise exceeding the Threshold Limit Value (TLV), with the majority being in the productive age group (59%) and having more than two years of work experience (69%). A total of 31% of workers reported hearing complaints and 63% experienced non-audiological symptoms, while more than half of the workers (53%) did not use personal protective equipment (PPE). Multi-level analysis revealed that noise originated not only from machines but was also influenced by workspace layout, worker behavior, and the lack of environmental protection systems. In conclusion, noise control requires a comprehensive strategy through workspace layout adjustments, engineering controls on machines, increased compliance with PPE use, and protection of the surrounding environment. The contribution of this study emphasizes the urgency of a multi-level approach in protecting worker health, improving productivity, and supporting the sustainability of furniture enterprises.

Abstract

The Kambang River is a river in Jambi City that passes through densely populated residential areas and shopping centers, making it vulnerable to pollution from both point and non-point sources. This study aims to model the water quality of the Kambang River using QUAL2Kw software on the Biochemical Oxygen Demand (BOD) and Ammonia as nitrogen (NH3-N) parameters in response to increasing discharge and pollutant levels from point sources. Sampling was conducted using grab sampling at nine points representing the upstream, midstream, and downstream segments. The test results were compared with the river water quality standards and similar waters, Class II, Appendix VI of Government Regulation No. 22 of 2021 concerning the Implementation of Environmental Protection and Management. River hydraulic data (discharge, width, depth, flow velocity, and riverbed slope) were used as input data in the QUAL2Kw worksheet. Data calibration was performed using trial and error, then data validation using the Root Mean Square Percentage Error (RMSPE) method. The results of water quality testing showed that the BOD and NH3-N parameters at all sampling points did not meet the established quality standards. The BOD test value ranged from 7.10 to 16.20 mg/L with a quality standard of 3.00 mg/L, and the NH3-N test results ranged from 3.03 to 14.13 mg/L with a quality standard of 0.20 mg/L. The model validation results using the RSMPE method for discharge parameters were 3.21%, BOD 3.88%, and NH3-N 0.46%, meeting the criteria of

Abstract

The utilization of durian peels, which are considered agricultural waste, remains minimal. One alternative to reduce the amount of durian peel waste is to use it as a basic material for producing bioethanol. Durian peels contain a significant amount of cellulose, making them highly potential as a basic material for bioethanol production. One of the key processes in producing bioethanol is fermentation, which is carried out with the help of microorganisms, specifically those from baker’s yeast or Saccharomyces cerevisiae. This experiment was conducted to determine the effect of fermentation duration and yeast mass on the resulting bioethanol content. The independent variables in this study are fermentation time and the mass of yeast used. The fermentation times used are 24, 48, 72, 96, and 120 hours, with yeast mass concentrations of 2%, 4%, and 6% mass/volume. After fermentation, the process continues to the purification or distillation stage to obtain the final bioethanol product. The obtained bioethanol will then be measured for its refractive index and analyzed using Gas Chromatography to determine its bioethanol content (%). The highest bioethanol content observed in this experiment was 29.33%, achieved with a fermentation time of 72 hours and a yeast mass of 6%. The quantitative analysis using GC showed the highest bioethanol content of 29.70%. These results indicate that durian peel waste has significant potential as a basic material for bioethanol production.

Abstract

Cans of soft drinks are a source of waste in Indonesia, as this inorganic waste cannot be decomposed rapidly and naturally. Aluminum takes about 400 years to decompose in the soil. A large amount of aluminum contained in the cans can be reused as goods or raw materials to produce hydrogen gas. Hydrogen is considered an environmentally friendly fuel regarding its very low emissions and high energy value. The hydrogen gas production process involves a reaction between aluminum metal and a catalyst. In this case, the use of a strong base catalyst such as KOH has been shown to produce more hydrogen. This experiment aims to utilize the cans as a material to produce hydrogen gas. This experimental process was carried out by reacting aluminum metal powder sourced from used drinking cans with varying aluminum masses of 3, 4, 5 and 6 g with water and KOH catalysts of 2, 3 and 4 M in a fixed bed reactor, with a process for 20 minutes at a temperature of 50 °C. The results of the reactions were analyzed using a Gas Detector Analyzer. This study shows that 6 g of aluminum catalyzed with 4 M KOH results in 66% Hydrogen gas, and 3 g of aluminum catalyzed with 2 M KOH results in 20% Hydrogen gas. This proves that increasing the amount of mass and concentration in the process increases the resulting volume of hydrogen gas.

Abstract

Heavy metals are dangerous environmental pollutants known to produce toxic effects on various organ systems in humans and other living organisms. Lead (Pb) is one of the common heavy metals found as a contaminant in the environment, capable of causing a range of negative impacts. This experiment was conducted to analyze the ability of a composite made from TiO2 and activated carbon derived from durian peel to absorb Pb ions present in laboratory waste. Additionally, this experiment also focused on calculating the adsorption kinetics. The activated carbon, weighing 25 grams, was activated with KOH using various solvent concentrations of 2, 3, and 4 M. The activated carbon was then added to 100 ml of titanium dioxide solution, and the mixture was dripped into an STTP-ethanol solution. The sample was stirred for varying durations of 10, 20, 30, and 40 minutes. The sample was filtered and then analyzed using AAS. The optimal time found in this study was 40 minutes, with an adsorption efficiency of 95.45% and an adsorption capacity of 4.2000 mg/g. The adsorption of Pb metal followed the Langmuir isotherm model.

Abstract

Glycerol is a byproduct of the biodiesel transesterification reaction that has a low purity level, also known as crude glycerol. Approximately 10-20% by weight of glycerol is produced as a byproduct of each biodiesel transesterification reaction. Crude glycerol contains many impurities, which has led to its suboptimal management. To reduce waste generated from the biodiesel transesterification reaction, further purification is necessary to produce high-purity glycerol with significant market value that can be used in various industries. Therefore, researchers aim to utilize natural zeolite from Malang as an adsorbent in the purification of crude glycerol. This study is conducted to understand the impact of chemical and physical activation on Malang natural zeolite in enhancing its characteristics as an adsorbent and to determine the optimal conditions (residence time and adsorbent weight) for achieving the highest purity glycerol through the adsorption process. The natural zeolite from Malang was prepared by activation with H2SO4 and calcined with 3 hours at 500°C. This was followed by an adsorption method using an adsorption column with varying residence times (30, 45, 60, 75, and 90 minutes) and adsorbent weights (20g, 40g, and 60g). The chemical and physical activation of Malang natural zeolite successfully enhanced its adsorption capacity by increasing the active pore size (0.97 μm – 4.42 μm) and reducing impurity ions, as well as raising the Si/Al ratio to 4.503. The optimal glycerol purity achieved was 86.33% with adsorbent weight of 60 grams and a residence time of 60 minutes.

Abstract

Tropical peatlands are among the largest terrestrial carbon reservoirs; however, their existence is increasingly threatened by hydrological alteration and intensive land-use practices. Pandan Makmur Village, Geragai District, East Tanjung Jabung Regency, is located within a transitional peat–mineral landscape dominated by oil palm plantations and functions as a buffer zone for the Sungai Buluh Peatland Protected Forest. This condition renders the area both strategically important and highly vulnerable to peatland degradation and subsurface carbon loss. This study aims to analyze the magnitude and spatial distribution of subsurface carbon stocks in peatlands using a Geographic Information System (GIS)-based approach. The study employed a semi-detailed soil survey method with a systematic grid design of 700 × 700 m. Field data included peat thickness, peat maturity level, bulk density, water content, and organic carbon (C-organic) content, analyzed at two soil depths: 0–30 cm and 30–60 cm. All parameters were integrated into a raster-based GIS with a spatial resolution of 20 × 20 m to calculate and map subsurface carbon stocks spatially. The results show that peat and peaty soils in Pandan Makmur Village cover approximately 1,048.7 ha and are predominantly composed of thin to shallow peat with a sapric maturity level. The total subsurface carbon stock is estimated at 370,566 tons, with the largest contribution originating from the 0–30 cm layer (93.2%), while layers deeper than 30 cm contribute only 6.8%. At the same thickness, the surface peat layer stores nearly twice as much carbon as the underlying layer. These findings confirm that the upper peat layer is the primary carbon storage compartment and simultaneously the most vulnerable to carbon loss. Therefore, protection of the surface peat layer and sustainable water management are essential for carbon emission mitigation and sustainable management of transitional peatland ecosystemsKeywords : Activation, Adsorption, Crude Glycerol, Natural Zeolite from Malang
