Abstract

Land cover change has a significant impact on the hydrology of watershed areas, including increasing flood risk. This study aims to analyze land cover changes in the Siborgonyi and Acai sub-watersheds between 2013 and 2022 and their impact on flood potential. The methods used include spatial analysis with GIS, flood modeling using HEC-RAS, and Curve Number (CN) calculations to identify changes in soil infiltration capacity. The results show that land cover changes have a substantial effect on the increase in flood risk. The reduction of forest areas and the expansion of built-up land indicate a large-scale conversion of natural vegetation into residential and infrastructure areas. CN values in 2022 increased across most areas, indicating reduced soil infiltration capacity and increased surface runoff. Flood modeling shows that both the extent and depth of inundation significantly increased in 2022, particularly in downstream areas with basin-like topography.

Abstract

Automatic Identification System (AIS) is a communication technology that plays an important role in improving operational safety and efficiency in the shipping industry. AIS allows ships to exchange real-time data on identity, position, speed, and direction, which helps prevent collisions and facilitates maritime traffic management by port authorities. In addition, AIS functions in search and rescue operations by providing accurate information on the location of ships in trouble. In terms of security, AIS allows monitoring of suspicious ships, thus helping in preventing illegal activities in the waters. This study aims to design and develop a prototype AIS receiver based on LoRa, Arduino, and LCD HMI. The LoRa module was chosen because of its ability to transmit data over long distances with low power consumption, which is suitable for the maritime environment. Arduino is used as the main microcontroller to control the system, while the LCD HMI serves as the display interface for the received data. After the hardware and software design was completed, the system was tested through functional testing and performance measurements using a spectrum analyzer to evaluate the strength of the LoRa signal at various distances. The test results show that the AIS receiver is able to receive data well up to 15 meters on land and 13 meters at sea, with a delay of 100 milliseconds. System performance degrades at longer distances due to environmental interference and signal attenuation. These findings provide insight into the effective limits of LoRa communication in maritime applications and can be used as a reference for frequency testing and optimization of LoRa-based long-range communication systems.

Abstract

One of the negative impacts of the mining process is acid mine drainage which is formed from the oxidation of minerals containing iron sulfur, such as pyrite (FeS2) and pyrothite (FeS) by oxidizers such as water and oxygen. To handle or control acid mine drainage, one way is to use activated carbon or often referred to as activated charcoal, which is a type of carbon that has a very large surface area. Charcoal is a porous solid that contains 85% to 95% carbon, produced from materials containing carbon by heating at high temperatures without oxygen (pyrolysis). Activated carbon made from palm shells is an adsorbent that can be used to treat coal mine acid water, so that the water meets standards for flowing into the environment. This study used concentration variants of 4 grams, 6 grams, 8 grams and contact times of 30 minutes, 60 minutes and 150 minutes. The results of this study show that the concentration of palm oil shell activated carbon adsorbent influences the reduction of iron (Fe) and manganese (Mn) metal levels as well as the pH conditions in acid mine drainage water. The higher the concentration and the longer the contact time, the more heavy metals are adsorbed, the contact time is the highest. The optimal concentration in this study was 150 minutes and the optimal concentration was 8 grams with physical activation.

Abstract

Open-pit mining system mining is greatly influenced by surface runoff, rainwater and groundwater. This surface water runoff is highly dependent on rainfall catchment areas, climate, and land use. Handling surface water runoff entering the mining area by creating water channels in the form of open channels and closed channels. One of the mining methods that is generally carried out in Indonesia is the open-pit mining method, which is widely found in East Kalimantan. Large basins will be created as a result of this mining technique, which could eventually serve as a reservoir for water from both surface runoff and groundwater. Therefore, an analysis of the runoff water output in the sump is required, sump capacity and appropriate pumping ratio so that mining activities can continue. The results of the study obtained the runoff discharge value in the sump was 4,071.37 m3/day, the sump capacity was 207,474.07 m3, the water balance in the sump with a total runoff discharge of 5,871.37 m3/day, and the existing volume of water in the sump was 24,771 m3. evaporation of 4.36 m3/day, infiltration of 91.36 m3/day, and pump discharge of 8,229.27 m3/day. A pumping ratio of 0.71 was obtained.

Abstract

Dump truck tires are an important component in the operation of wheel-type units that require routine inspection because they directly affect the availability and performance of the transport equipment. In the OHT 777 type unit, six tires are used with a configuration of two tires in the front and four tires in the rear. This study aims to evaluate tire performance through the analysis of Key Performance Indicator (KPI) parameters, namely Ton Kilometer Per Hour (TKPH), Tread Utilization Rate (TUR), and tire life (lifetime), in order to assess the achievement of performance targets. The research method uses a quantitative approach with actual data collection in the field, including the preparation stages, primary and secondary data collection, data processing, and preparation of the final report. The data is processed to obtain the tire KPI value. The results of the analysis show that the TUR value for MICHELIN brand tires is 68.9% and BRIDGESTONE is 70.7%, still below the company's target of 85%. The TKPH value for the OHT 773 unit is 149 (with a TKPH rating of 207) and the 777 unit is 241 (with a TKPH rating of 514). The actual lifetime of BRIDGESTONE tires was recorded at 1,698.6 hm and MICHELIN at 2,268 hm, far below the target of 8,500 hm. Tire damage found included impact (23%), sidewall damage (18%), run flat (18%), bread damage (18%), sounder cut (14%), and foreign object puncture (9%). This evaluation is expected to be the basis for improving tire management, so that tire performance in the future can be more optimal and support the smooth operation of the unit.

Abstract

Landslides or commonly called landslides are a disaster that often hits areas with tropical climates. The damage caused by landslides is most dominantly structural damage such as damaged road sections that are cut off. At the research location, there was a landslide that resulted in the obstruction of the road flow which was originally two lanes to one lane, it is feared that landslides will occur again, so one of the landslide prevention techniques is to use retaining walls. Based on this, this study is deemed necessary to determine the slope safety factor and to determine the safety of the slope after using retaining walls. The purpose of this study was to determine the level of slope safety without being given a load, the level of slope safety after being given a load of 25 Kpa and the level of slope safety after being given a load of 25 kpa and the addition of a retaining wall on the research slope using a Retaining Wall. In this study using the Finite Element Method in the calculation to find the level of safety of a slope, the researcher used the help of Plaxis 2D V20 Software, and the results of the calculation obtained a slope safety factor of 1.31, after being given a load of 25 kpa the slope safety factor was 1.14 and after being given a retaining wall the slope safety factor increased to 2.46.

Abstract

This study aims to analyze the factors that cause the decline in intercooler performance on the main engine of KM Bintan Utama, its impact on engine performance, and the corrective measures that need to be taken. Based on the analysis, three main factors contribute to the decrease in intercooler performance: dirty air fins in the intercooler, lack of routine maintenance, and blockage in the seawater pipe filter. This decline in intercooler performance significantly affects the main engine, such as increased engine temperature, which can lead to damage to critical components. To address this issue, several actions need to be taken, including cleaning the intercooler air fins regularly and ensuring maintenance is carried out according to the recommended manual. Proper maintenance implementation will help maintain the performance of the main engine and extend the life of the intercooler and other components.
