Abstract

Maritime tourism in Indonesia holds substantial potential for future growth, contributing to the well-being of coastal communities. Amphibious aircraft, capable of taking off and landing on both water and land, provide an efficient means for tourists to explore the country's diverse regions. Accurately predicting hydrodynamic loads is therefore essential to ensuring the reliability of amphibious float structures. This study aims to validate the feasibility of replacing cable-based accelerometer sensors with wireless alternatives to measure impact loads on an amphibious aircraft float model. Accelerometers were mounted on the float model, and impact loads were tested using a launcher in a mechanical workshop prior to hydrodynamic tests in a water tank. The data revealed that the sensors effectively captured impact loads, with measurements averaging a 3.7% deviation from theoretical values. The maximum impact force recorded was 1.98 g, and the minimum was 0.61 g. These findings support the use of wireless systems for hydrodynamic impact load testing in water tank environments.

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.
