Abstract

PT Berau Coal is a company that has held the Coal Mining Work Agreement (PKP2B) since 1983, with an area of approximately 243,146.60 hectares located in Berau Regency, East Kalimantan Province. As a mining industry, the company must play a role in maintaining hydro-orological functions and protecting flora and fauna. The restoration of forest functions is crucial for providing environmental services, including efforts to act as a carbon (C) producing area and absorbing carbon dioxide (CO2). PT Berau Coal has carried out reclamation and revegetation in its post-mining areas, but until now, no research has been conducted in the revegetation areas of PT Berau Coal. Therefore, this study aims to determine the distribution of biomass and carbon stock in the revegetation areas and planting years at the Binungan site of PT Berau Coal from 2015 to 2022. The method used to calculate carbon stock and biomass involves field sampling and remote sensing using MicaSense multispectral aerial photos. Biomass and carbon stock estimation with aerial photos is conducted by calculating the plant greenness index using NDVI, followed by regression with field biomass. The regression model used includes four types: linear, quadratic, cubic, and exponential. These models are evaluated to find the best fit model with accuracy tests using Root Mean Square Error (RMSe), Mean Absolute Error (MAE), and Mean Absolute Percentage Error (MAPE) to determine the modeling accuracy. The results show that the best model for estimating biomass and carbon stock is the exponential regression model with a correlation value of 0.84. This correlation value falls into the category of a fairly high correlation. The RMSe produced in the accuracy test is 15.65, with an accuracy rate of 73%. The estimated carbon stock value for each planting year is 70,817,156.852 Kg/Ha (2015), 79,837,036.531 Kg/Ha (2016), 49,654,443.503 Kg/Ha (2017), 47,047,989.557 Kg/Ha (2018), 35,219,578.867 Kg/Ha (2019), 19,693,198.417 Kg/Ha (2020), 31,335,533.541 Kg/Ha (2021), and 31,335,533.541 Kg/Ha (2022). The modeling results indicate that the older the plants, the higher their NDVI, resulting in greater biomass and carbon stock in the area.

Abstract

One of the materials that may be utilized in polymer matrix composites is high-density polyethylene (HDPE) plastic. Large amounts of HDPE plastic waste can harm the environment. Therefore, a solution is needed to overcome this problem. One solution to reduce plastic waste is to utilise it into polymer composite roof tiles. Roof tile surfaces are subjected to the greatest amount of solar heat radiation. This study aims to analyze the effect of variations in the composition of HDPE and teki grass on the value of solar radiation heat transfer and the value of thermal stability in polymer composite roof tiles. This research uses an experimental method by composites HDPE and teki grass with variations in the weight of teki grass used by 0%, 10%, 15%, and 20%. The results show that 20% teki grass composition in the composite produces low radiant heat compared to 0% teki grass composition which tends to be higher. according to the findings of the thermal stability test., The maximum thermal stability was seen in the composite with 0% fiber composition. While the most unstable composite is at 20% fiber composition with a 5% weight loss at 164.47oC and 10% at 278.27oC.

Abstract

In the operation of a multipurpose terminal in a port (terminal that can serve and be berthed to more than one type of a ship), the position of planning an optimal berth allocation for ships is essential to maintain. Berth allocation planning (BAP) is considered tactical planning that can impact the performance of a terminal and the cost of a ship in a port. That is because the longer the waiting time of a ship that waits to be berthed, the smaller number of ships will be served by the terminal, and the higher the cost will be borne by the ships. This paper, based on a case study in Terminal Jamrud of Tanjung Perak Port of Indonesia, will discuss a Mixed Integer Linear Programming (MILP) mathematical model of a BAP to minimize the ships’ waiting time to berth with consideration to the tailored conditions of the multipurpose terminal. The results show that the optimization model yielded reductions in the datasets 1 to 3 tested on the North/West and 4 to 6 on the South pier. There are savings in the waiting time reduced in hours, which are 403 (12,82%), 189 (26,18%), 418 (30,74%) for the North/West pier and 34 (16,43%), 1663 (88,13%), 475 (46,75%) for the South pier.

Abstract

Corrosion is a significant issue in steel constructions, and zinc coating (electroplating) is one of the methods used to protect steel from corrosion. This research aims to analyze the effect of voltage and duration of zinc coating on low carbon steel A36 through the electroplating process on the corrosion rate and coating thickness. An experimental method was employed, varying the voltage (6, 8, and 10 Volts) and coating duration (10, 20, and 30 minutes) during the electroplating process using a ZnO solution. The corrosion rate was tested electrochemically in a 3.5% NaCl solution. The results showed a significant correlation between voltage, coating duration, corrosion rate, and coating thickness. Higher voltages and longer durations produced thicker zinc coatings and reduced the corrosion rate. The optimal conditions were found at 10 Volts for 30 minutes, producing a 160 (Mu)m thick coating and the lowest corrosion rate of 0.00318 mmpy. The minimal coating condition, 6 Volts for 10 minutes, resulted in a 30 (Mu)m thick coating and a corrosion rate of 0.050120 mmpy.

Abstract

The advancement of ship production technology in Indonesia involves the implementation of modern techniques integrating computer-based design and production facilities, such as Computer-Aided Manufacturing (CAM) for operating production machines utilizing Computer Numerical Control (CNC). One specific type of CNC machine utilized in ship production is the plasma cutting CNC machine. Despite being crucial to production, these machines frequently encounter failures that impede the production process. Through prior failure analyses conducted by the company, it has been identified that the dust collector air hose component exhibits the highest failure rate with six distinct failure modes. This article conducts qualitative and quantitative analyses of the causes of failure in the air hose dust collector of CNC plasma cutting machines using the Fault Tree Analysis (FTA) method. FTA is employed as a method to ascertain the fundamental causes of the event. The analysis results are utilized to provide recommendations for controlling objectives related to occupational safety. Six failure trees are generated, comprising a total of 28 basic causes. The most frequently occurring types of basic causes are associated with workers, methods, and materials. The probability of occurrence for the minimal cut set of each failure tree has been successfully computed. These calculations reveal that all top events possess probability values exceeding 76%. Specifically, the event of the dust collector air gap breaking has the highest probability value, reaching 99.88%, which is a composite of 15 basic causes. Control recommendations are provided in the form of substitution, engineering solutions, and administrative controls.

Abstract

High stability is imperative, safeguarding against the unpredictable nature of the marine environment and promoting a secure working platform for crew members to do fishing operation. The aim of this study is to analyze the effect of laying solar panels on the deckhouse of small fishing vessels 20 GT. The additional load above which causes weight gain and will affect the ship's center of gravity is became the first effect of Fishing vessel stability. The second effect is on how the fishing vessel performs when there is a solar panel on the vessel. The data were collected by measuring the stability according to A.N Kyrylo’s method with standard checks according to the IMO (International Marine Organization). Code on Intact stability calculated the ship motion by using the STRIP method and using the JONSWAP method to measuring the wave characteristics with the help of Maxsurf software. The results of this research show that the installment of solar panels above the deckhouse does not really affect the stability, where the results were meets the IMO standard criteria. The successful fishing operation of the vessels studied will only have a good performance at 1.5 meters, according to the seakeeping analysis.

Abstract

Small pelagic purse seine vessels in Jakarta are dominated by vessels with a length of 14.5 m. The vessel's hull construction was made by a traditional vesselyard using wood. The construction process only relies on the skills and habits of craftsmen. The choice of engine is only based on the size of the vessel and the price of the engine without calculating resistance. In general, the power of the purse seine main engine as the main mover is not suitable, causing wasteful fuel consumption. The fishing vessel engine used by MV Putra Abadi comes from a modified truck engine so that the fuel used does not comply with specifications. This research aims to determine the amount of power needed to move a Putra Abadi fishing vessel. The method used is direct observation by taking direct measurements of the dimensions of MV Putra Abadi. Next, the engine resistance and power are also calculated using the Holtrop resistance method in software. The Putra Abadi fishing vessel based on hydrostatic calculations showed that the block coefficient (Cb) is 0.425 at a speed of 7 knots, the resulting resistance is 2.5 kN. While at a maximum speed of 8 knots the BHP is 98.82. The power requirement of Putra Abadi fishing vessel according to this calculation is only 46% of the engine power currently used.
