Abstract

Bukit Raya Village, Sepaku District, North Penajam Paser Regency is located in Ring 1 of the National Capital City (IKN). The village faces public health challenges due to population growth and significant environmental changes. The more population, the more important it is to maintain a sustainable environment, and waste is one of the focal points to achieve this goal. Pollution from waste cannot be separated from the activities of the community. The research was conducted to investigate the effect of applying appropriate technology BSF (Black Soldier Fly) and Tampuk (Tube for Compost) on efforts to improve waste sorting habits at the source. Educational activities and technical guidance can increase public understanding of the definition of waste, why waste needs to be managed, procedures for sorting waste, and how to manage waste at the source. FGD (Focus Group Discussion) with Bukit Raya Village and NGOs as waste managers provided information that waste management in Bukit Raya Village was not up to standard. Based on the results of participatory observation and scoring methods, it can be concluded that the presence of advanced treatment in the form of appropriate technology for BSF (Black Soldier Fly) and Tampuk (Tubes for Compost) cultivation will provide an increase of 4.4% in the 3rd week of September, 26.31% in the 4th week of September, 37.5% in the 1st week of October, and 100% in the 2nd week of October 2024.

Abstract

One of the main requirements in polymer processing is heat. A fired heater is used in the Heat Transfer Medium unit to obtain heat. The efficiency, heat loss, and specific consumption of fired heaters greatly impact the efficiency of energy use in processing. According to SNI, to maintain the efficiency of the fired heater, it is necessary to periodically review its performance using direct and walkthrough methods. The analysis results from three consecutive days showed an efficiency of 87%, 89%, and 89%. The heat loss was 13%, 11%, and 11%. The specific consumption was 70.66, 72.65, and 72.69 Nm³/ton. Overall, these values meet SNI standards: 92% efficiency, 10-15% heat loss, and ≥74 Nm³/ton specific consumption. However, to maintain or increase the efficiency value, it is necessary to monitor operating conditions and conduct regular periodic checks to prevent system leaks that increase heat loss and reduce efficiency.

Abstract

The global climate change phenomenon is prompting initiatives aimed at transitioning energy sources towards more sustainable pathways. Pyrolysis technology offers significant potential in the conversion of biomass and plastic waste into alternative energy sources. The objective of this literature review is to analyze the effect of feedstock type on pyrolysis product characteristics and its potential as an energy source. The results of the literature study indicated that the feedstock from biomass possessed a lower calorific value in comparison to waste composed of polymer compounds. The pyrolysis process yields three primary byproducts: char, bio-oil, and gas. Char can be utilized as a solid fuel, such as briquettes. The processing of bio-oil into liquid fuel, bioethanol, is a viable option. The pyrolysis gas is a versatile material that can be utilized as a fuel for stoves and generators. Pyrolysis, a promising technology, has the potential to convert biomass and plastic waste into alternative energy. The type of feedstock employed is a critical factor in determining the quality and quantity of pyrolysis products. Through process optimization and technological development, pyrolysis has the potential to play a substantial role in reducing reliance on fossil fuels and addressing environmental concerns.

Abstract

Peat water originates from the incomplete decomposition of plant material in low-lying and swampy areas. It has properties that can harm human health, such as high acidity and a reddish-brown colour. It also contains dissolved metals, such as iron and manganese, and has a high organic content. The aim of this study is to treat peat water using the electrocoagulation method in order to improve its quality in line with clean water quality standards. Electrocoagulation uses electrical energy to coagulate solids and reduce the content of dissolved metals. This study was conducted using peat water from Pandan Jaya Village in the Geragai District of the East Tanjung Jabung Regency in the Jambi Province. Electrical voltages of 10, 20 and 30 volts were used, as well as contact times of 60, 120 and 180 minutes. After electrocoagulation treatment, the results showed that iron levels decreased by 98% (from 4.28 mg/L to 0.0871 mg/L), manganese by 87.6% (from 0.2667 mg/L to 0.0330 mg/L), total suspended solids by 92.2% (from 24.43 mg/L to 1.9 mg/L), and pH by 100% (from 3.10 to 7.41). These results suggest that electrocoagulation is an effective method of reducing peat water pollution and improving its quality to meet national clean water standards.

Abstract

The demand for clean water in Indonesia has been steadily increasing, but water pollution from industrial wastewater, especially from tofu production, remains a significant challenge. This study investigates the potential of fly ash and bottom ash as adsorbents to reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in tofu wastewater. Laboratory experiments were conducted with different adsorbent doses of 25, 50, and 75 grams. The adsorption process involved stirring the samples for 60 minutes, followed by a sedimentation period of 120 minutes. The results showed that fly ash was more effective than bottom ash in reducing COD and BOD levels. At a dose of 75 grams, Fly Ash achieved a 72% reduction in COD (from 0.8672 mg/L to 0.2438 mg/L) while Bottom Ash resulted in a 68% reduction with a final COD concentration of 0.2735 mg/L. A similar pattern was observed in the reduction of BOD. These results indicate that both fly ash and bottom ash can be effective and environmentally friendly alternatives for the treatment of tofu wastewater.

Abstract

This study aims to plan the design of a constructed wetland as a tertiary treatment to remove microplastics in wastewater so that it is safe to discharge into water bodies or the environment. The design site is the Anaerobic Upflow Filter (AUF) type wastewater treatment plant in Jambi City. The design uses the Sub Surface Flow Constructed Wetland (SSFCW) system and the Horizontal Sub Surface Flow (HSSF) system with the selected plants being Phragmites communis. The planned design is 1 unit for a treatment capacity of 24 m3/day, which is located downstream of each AUF type WWTP in Jambi City. The constructed wetland design refers to the design criteria and design calculations contained in Book A, a guide for the calculation of fecal sludge treatment buildings. This study also calculates the Bill of Quantity (BOQ), which is determined based on the dimensions of the design drawing, and the Resource Allocation Plan (RAB), which is determined based on the amount of work multiplied by the Analysis of the Unit Price of Work (AHSP). AHSP refers to the Jambi Governor Regulation No. 1 of 2024 on Unit Price Standards. Based on the research results, it was found that the dimensions of the constructed wetland design were 64 m × 16 m × 0.9 m, so the estimated cost for the construction of the design was IDR 405,415,773.84 with an estimated microplastics removal efficiency of 100%.

Abstract

Clay shale is a type of clay soil formed by fine-grained sediments such as clay. Clay shale is very hard under closed conditions, but under open conditions, exposed to sunlight, water and air for a long time, its state changes and becomes weak, which ultimately causes a decrease in soil shear strength. The purpose of this thickness comparison is to analyze the feasibility of clay shale soil as a base layer for highway pavement with the thickness of MDP 2024. The analysis results show that the deflection and stress that occur in the flexible pavement structure are both safe/feasible. Thus, both pavement thicknesses can be implemented. The results of stress and deflection from IKN design data are the maximum stress of 823.2 kN/m2 < 1,450 kN/m2 (allowable stress) and 2.668 x 10-3 m < 2.5 10-2 m (allowable deflection). As for the results of stress and deflection with thickness The 2024 Road Pavement Design Manual method is used, the maximum stress is 1075 kN/m2 < 1,450 kN/m2 (allowable stress) and 1,601 x 10-3 m < 2.5 10-2 m (allowable deflection). It is recommended to use the design pavement thickness from the IKN design for the evaluation because the stability of the flexible pavement structure in the IKN design is better than the pavement structure using the MDP 2024 method.
