Abstract

PT Pindad (Persero) is a manufacturing company engaged in the production of defence equipment. In the production process, PT Pindad (Persero) generates various types of waste such as slag, scrap, tap and flash. The management of these wastes is carried out through the remanufacturing process in the Support Department of the Transportation Infrastructure Division. However, irregularities in the storage and distribution of waste cause accumulation, waste of space and operational obstacles. This research proposes the creation of a waste storage SOP using the First Waste First Out (FWFO) method as a solution to waste storage and distribution management. FWFO is the author's design, adapted from the FIFO (First In First Out) method, designed to accelerate waste turnover, prevent quality degradation such as corrosion of metals, and improve operational efficiency. The research was conducted using a qualitative method with primary data sources from interviews with the head of the smelting section and the head of the warehouse, and secondary data sources from literature and previous reports. It is expected that the draft SOP for waste storage using the first waste first out method will effectively reduce the accumulation of waste, maximise the use of waste according to specifications, and improve the efficiency of storage and reprocessing at PT Pindad.

Abstract

Burning bricks can pollute the surrounding air because the smoke produced contains CO and CO2 emissions. This burning causes air pollution and a greenhouse effect (damage to the ozone layer) due to the emission of carbon monoxide gas. Air containing CO and CO2 emissions can be cleaned using the absorption method. The use of a wet scrubber and chemical absorbents that are alkaline in nature will help maximise the absorption process. The aim of this research is to test which absorbent among KOH, NaOH and H2O has the best performance in reducing CO and CO2 levels using a wet scrubber reactor design with pall ring media in the brick burning process. The independent variables used consist of variations in absorbent type, absorbent concentration and media height. The absorbents used are NaOH, KOH and H2O. The respective concentrations of NaOH and KOH absorbents used were 2N, 4N and 6N. The height of the pall ring media was varied to 20 cm and 40 cm. The highest percentage reduction of CO reached 97.9% and CO2 96.0% when using 6N KOH absorbent and 40 cm pall ring media.

Abstract

The geoid model is crucial for all nations as the primary height reference. Given that numerous countries have developed their geoid models, local geoid modelling is essential for Indonesia. According to the Indonesian Geospatial Reference System (SRGI 2013), which encompasses the national height reference system, it is indicated that not all areas of Indonesia possess a geoid model with a high degree of accuracy. The geoid modelling in Indonesia has been conducted incrementally. In local geoid modelling utilizing gravimetric techniques, specifically within the Remove Compute Restore (RCR) framework, two approaches for ascertaining residual undulation are the Fast Fourier Transform (FFT) Method and the Least Squares Collocation (LSC) Method. This study examines a comparison of the two methods, focusing on the accuracy of the geoid model and the factors that affect its precision. This study's findings demonstrate that the least squares collocation geoid model is the most precise geoid model in the Pangkal Pinang region and its vicinity, achieving an accuracy of ±0.131 m. The accuracy of the Fast Fourier Transform method is ±0.149 m for the 2D Spherical Multiband FFT approach and ±0.159 m for Haagman's 1D Spherical FFT approach.

Abstract

The amount of plastic waste continues to increase with population growth. Decomposition of plastic waste takes tens to hundreds of years. The use of conventional plastics, especially plastic bags that are commonly used by the public, continues to increase, which has a negative impact on the environment. Handling plastic waste using biological methods is an easier, cheaper, and safer solution for the environment. In the degradation process, microorganisms play an important role as decomposers of waste using enzymes in their bodies. However, recent research has revealed that macroorganisms, particularly insects, can accelerate biodegradation. This study examines the biodegradability of environmentally friendly plastics by summarizing scenarios from recent research on plastic biodegradation by macroorganisms and microorganisms. Macroorganisms that have been widely studied for plastic degradation include Tenebrio molitor larvae (T. molitor) and microorganisms derived from EM4 bioactivators. In addition, this study also summarizes the review of the mechanisms, parameters, approaches to biodegradation outcome variables, comparison of the effectiveness of biodegradators using rate biodegradation modeling, and biodegradation reactors, as well as product parameters that are considered so that are considered safe for the environment

Abstract

Since 2006, Indonesia has led global production and export of palm-based edible oils. Government policies focused on advancing agriculture and agro-industries, particularly in downstream product development, provide opportunities to increase the economic value of these products, including palm oil products. Efforts to enhance downstream products include maximizing all palm oil potentials, including its waste. Global CPO production based on 2024 data is 79.6 million tons per year, with Indonesia contributing 59%. The potential waste is also very large, including the final waste which still contains around 20-25% oil and 3-5% phytonutrients. Proximate analysis and β-carotene content studies are used to evaluate the potential of CPO liquid waste for poultry feed. Proximate analysis results show low nutrient levels, including protein (<0.04%), carbohydrates (1.37%), total carbohydrates (<0.02%), total energy (5.20%), and crude fiber (<0.02%), making it unsuitable as a poultry feed substitute. However, based on β-carotene data, the waste can be used as an additive in poultry feed if stored for less than 28 days. The β-carotene degradation process follows zero-order reaction at heating and storage conditions (under room and dark storage).

Abstract

The foundation is an important part of building construction, acting as a support for the building and transferring loads evenly from the upper structure to the ground. In construction projects, one of the most important activities is to test the bearing capacity of bore piles using the Pile Driving Analyser (PDA) method. The purpose of this test is to ensure that the capacity of the bored pile can meet the structural requirements of the toll road, particularly in the face of significant vertical and lateral loads. Improving the efficiency of the PDA (Pile Driving Analyzer) testing method is an important challenge in the foundation of bored piles in infrastructure projects. This study discusses the analysis of the use of the Frame Portal PDA as an alternative to the crane hammer method. The analysis includes quality, time and cost aspects on the Toll project. The results show that the PDA Portal Frame method is more efficient with a cost saving of Rp109,010,524.00 and a reduction in implementation time for 2 days of test points compared to the crane method. In addition, the PDA Portal Frame structure has a maximum deformation of 0.030 mm, which is within safe limits according to SNI 2847-2019.

Abstract

The plastic recycling industry holds significant potential to reduce environmental impact and create new economic value. However, this industry faces challenges such as high production costs, process inefficiencies, and increasing sustainability demands. This article discusses operational management strategies, including the implementation of lean manufacturing, IoT-based smart technologies, and circular economy principles. Lean manufacturing focuses on waste reduction and efficiency improvement, while IoT enables real-time data analysis to detect and resolve inefficiencies. The adoption of circular economy principles demonstrates a reduction in the use of new raw materials, production costs, and waste. The findings reveal that combining these strategies enhances operational efficiency, reduces expenditures, and supports environmental sustainability. This article provides recommendations for the plastic recycling industry to innovate continuously in addressing global challenges
