Abstract

Sedimentation at the mouth of the Palu River is the cause of frequent flooding in Palu City. This study aims to understand the hydrodynamic conditions and longshore sediment transport around the mouth of the Palu River. Hydrodynamic conditions were analyzed by measuring velocity and current direction, salinity, discharge, breaking wave height, breaking wave depth, wave incidence angle, water density, and water depth. While the amount of longshore sediment transport was calculated based on the CERC empirical formula. The results revealed that the distribution of currents at the mouth of the Palu River was dominated by river currents, where the amount of seawater in the mouth of the river was small. This could be seen from the small salinity value, which ranged from 1 ‰ to 5 ‰. The longshore sediment transport around the Palu River estuary is 36.06 m3/day, where this sediment resulted in silting at the Palu River estuary during deposition.

Abstract

Flood is a natural event that is difficult to predict because it comes suddenly with an erratic period, especially in East Balikpapan. There are several important factors that cause flooding in South Balikpapan, including the slope, land cover, and rainfall. The purpose of this study was to determine the flood-prone areas of East Balikpapan based on analysis of the factors that cause flooding, such as rainfall, slope, and land cover and give recommended mitigation.In addition, this study is also to obtain the weight of each factor that affects flooding. The data used in this study include digital data on administrative boundaries, rainfall data, digital data on topographic maps, digital data on land use maps, and field observations. The data is processed using an application based on a Geographic Information System (GIS). The overlay process is carried out using ArcGIS and the weighting is obtained from the Analytical Hierarchy Process (AHP) method. The research area has three categories of areas prone to flooding: not prone, vulnerable, and very prone to flooding. Areas that are not prone are 31.2%, vulnerable 0.001%, and very vulnerable 68.7% of the total research area predominantly located in the south of the study area with the dominance of residential land cover. Recommended mitigation recommendations are the arrangement and construction of good irrigation channels, directly connected to the sea, land clearing paying attention to the marbles of the territory and bozem development

Abstract

The Environment and Forestry Metrics stated that data on waste piles in Indonesia in 2020 reached 67.8 tons, 45% of which was poorly managed plastic waste. The large amount of waste produced causes Indonesia to become the second waste producer in the world. The level of waste management that is still minimal is the main thing that causes Indonesia to become a "polluting" country in the world. Waste Power Plant is a waste management solution to reduce the amount of waste and become an alternative energy for generating electricity in the community. The purpose of this research is to provide an alternative by creating a waste power plant as a producer of renewable electrical energy. This research begins with collecting materials and continues with the design of components such as furnaces, boilers, steam turbines, DC generators which are integrated into one, and waste as fuel. The components that have been worked are then tested with plastic waste and wood waste are collected and then put into the furnace, then the waste is burned to boil water in the boiler. Changes in the speed or relative velocity of this steam cause a force turns the turbine. The turbine that is connected to this generator will then rotate the generator to produce electricity. Based on the results of testing the solid waste power plant, the maximum voltage value is 13.76 V.

Abstract

Geothermal features can be observed in areas of active volcanism, or areas that have inactive volcanoes. In non-volcanic areas, the temperature of rocks within the Earth also increases with depth. This temperature increase is known as the Geothermal Gradient. If water percolates deeply enough into the crust, it comes into contact with hot rocks and can circulate to the surface to form hot springs. The collection of field hydrothermal data during field study with the help of portable instruments. The different physical parameters of the thermal springs such as temperature, pH, colour, and odour of thermal fluid are noted. The temperature of the thermal springs ranges from 43oC to 48oC. The pH value of the thermal waters shows a neutral (pH 6-6.6) and sulphur odour is discernible particularly. Based on geological, the system geothermal energy that develops is geopressured.

Abstract

Cipluk Field is located in Klantung, Kendal, Central Java. It is an oil field in Indonesia. This field has abandoned status but until now oil seeps are found in the rocks around the field. Based on regional geology by Thanden et al. (1996), the estimated reservoir is Kerek Formation. The formation is exposed around and south of the field, around Lutut River. This research was conducted to determine the rock characteristics of Kerek Formation and to be analog to determine reservoir rock characteristics of the Cipluk Field petroleum system. This research is based on field evaluation data. Data were obtained through direct field investigations aimed at knowing the geological conditions of the research area. The main data used consisted of field observation data, rock samples, SRTM images, seismic data, and well data. Kerek Formation in the study area is divided into three members and only two members are exposed on the surface, Middle Miocene Kerek Formation and Late Miocene Kerek Formation. Middle Miocene Kerek Formation has characteristics with interbedded claystone-sandstone dominantly with limestone on the bottom and dominantly with sandstone on top. This member has a fairly good character as a reservoir for the Cipluk Field petroleum system based on its rock composition and geometry.

Abstract

Determination of the source of the earthquake has been carried out in the north arm of Sulawesi. The earthquakes analyzed were a local earthquake with a magnitude of more than 5 M. The source of the earthquake is the main variable in earthquake disaster mitigation. Determining the source of the earthquake using the arrival time of the P/S wave. The arrival times of the P/S waves were validated with a Wadati’s chart to test the convergence of the data. Determination of the source of the earthquake was analyzed using HYPOINVERSE. The source of the earthquake obtained has variations in depth and position. Comparison with the catalog shows a significant difference.

Abstract

Flare stack is a fire tower installation to burn off-specification gas that is not processed perfectly in the oil and gas processing or or in the petrochemical process. The purpose of this study is to provide a technical description of the condition of the flare stack installation in the refinery industry after being used for 40 years. The research method used is a technical inspection method with limited testing and inspection with a case study approach to problems in the flare stack installation. The results show that the building under the flare stack installation has experienced material degradation in the form of carbonation of the concrete structure to a depth of 5.5 millimeters and causes the concrete to become brittle. The results of the study recommend that it is necessary to immediately relocate and replace the existing flare installation because its estimated life span is 2 years. The results also recommend that the location that is considered suitable and suitable for flare stack installation is in the Balikpapan Bay area in the form of an offshore flare platform.
