Abstract

Currently, the weather in Indonesia has been greatly affected by climate change. This is evidenced by extreme weather events in early 2020 which are predicted to occur more frequently in Indonesia. Bad weather in the form of high rainfall will potentially cause hydrometeorological disasters such as floods and landslides. To anticipate the occurrence of landslides that have the potential to disrupt regional development, it is important to conduct research to map landslide-prone areas in the province of West Kalimantan. This research is in line with UNTAN's strategic research plan to contribute to disaster management and climate change. This research combines overlay and measurement methods with geoelectric methods. The overlay method is used as a method to map landslide susceptibility based on scoring calculations from land parameters. The mapping is expected to produce a map of the landslide-prone zone which can then be studied further. Assessment of landslide potential through slip plane analysis using resistivity geoelectric method. From the mapping and direct observation, it is proved that the high landslide susceptibility values correlate with the landslide occurrence in Sabang Merah, Sanggau. Based on the resistivity measurement there found the potential landslide slip surface that is connected with the dip of rock layers in the area.

Abstract

The increasing demand for energy and fossil fuels has caused a shortage of energy, so renewable alternative energy is needed to help solve this problem. Biomass waste has significant potential as a briquette-making material. The production of briquettes as an alternative energy source made from biomass from Alaban wood charcoal and rubber seed shells is one solution. The research was conducted to determine the characteristics of briquettes with differences in composition variations, including moisture content, ash content, and caloric value in accordance with SNI 01-6235-2000 standards. Alaban wood charcoal and rubber seed shells that have been carbonized and made into powder were then sieved with a 60 mesh sieve and then weighed and mixed with a rubber adhesive, and then molded with a pressure of 200 kg/cm2. The composition variations used for Alaban wood charcoal and rubber seed shells are 100%:0%; 0%:100%; 70%:30%; 60%:40%; 50%:50%; 40%:60%; 30%:70% with 9% rubber adhesive in the total weight for each composition and dipped in used cooking oil for 3 minutes. The characteristics of the resulting briquettes are moisture content of 0.69%-2.06%; ash content of 3.34%-4.91%; and caloric value of 7.863kcal/g-8.042kcal/g. The results of this research as a whole have met the standards. The more rubber seed shells that are added, the lower the moisture content, the higher the ash content, and the caloric value. Briquettes with a composition of 30% Alaban wood charcoal and 70% rubber seed shells produce a caloric value of 7.953 kcal/g, moisture content of 0.75%, and ash content of 4.19%.

Abstract

Proton therapy is a treatment modality which can deliver dose precisely to cancer tumor in comparison to photon therapy, However, study about the biological effect of proton therapy are not well known. In this study, simulation of proton bombardment with energy 110 MeV to water is conducted using Geant4 software. The selection of water as the object of proton bombardment due to majority of human body is consisted of water. Water molecule in this simulation is a cube shaped with 10 x 10 x 10 cmand surrounded by PMMA material with 0.5 cm thickness. From the simulation results, it can be seen that <2% neutrons particle are formed due to the interaction of proton particles with water material. Small dose of neutron can be dangerous for body because it has high biological effectiveness and thus even a small absorbed dose might cause negative side effects in the patient.

Abstract

Cotton fabric is a comfortable clothing material to wear in tropical climates. In addition to the comfort aspect, cotton cloth is expected to be able to protect the skin from the dangers of sun exposure. This research was conducted with the aim of knowing the optimum amount of protection produced by cotton cloth, determining the type and color of cotton cloth that is most effectively used as a protector, and knowing the SPF (sun protection factor) value category based on the type and color of cotton cloth. This study used three types of cotton cloth, each consisting of four colors, as well as a Digital Environment Multimeter which was used to measure the intensity of sunlight in units of lux. The protection value is obtained by comparing the intensity of sunlight without a cotton cloth protector (lux) with the intensity of sunlight using a cotton cloth protector (lux). The results obtained show that the most optimum protection value is found in black toyobo cotton cloth with an SPF value of 54.4 and a transmittance of 1.8%. The cotton fabrics that provided the most effective protection based on type and color were black and blue toyobo, medina and Japanese cotton fabrics. Based on the SPF value obtained, it can be seen that black and blue toyobo cotton fabrics, and black madinah cotton fabrics have a very good protection category. The black and blue Japanese cotton fabrics, as well as the blue medina type, have a good protection category, while the orange Toyobo cotton fabrics have a sufficient protection category.

Abstract

Central Sulawesi is an area that is prone to earthquakes. The movement of the Palu Koro Fault is the trigger for most of the destructive earthquakes in the Central Sulawesi region. This study aims to analyze seismicity based on the seismotectonic parameter b-value, analyze coulomb stress changes and based on the seismicity level analyze the risk of earthquakes in Central Sulawesi in the 1996-2022 range. This study uses data from the 1996-2022 earthquake catalog from the USGS catalog. Data from the USGS catalog was then processed using Zmap v6 based on MATLAB to obtain the b-value seismicity parameter using the maximum likelihood method. Data processing for coulomb stress is processed using MATLAB based Coulomb 3.4.2 software. Based on the results of the analysis, the b-value in zone 1 to zone 3 is 0.653 – 0.777. The results of the analysis of changes in coulomb stress obtained positive coulomb stress changes indicated by the red lobe with  a value of 1 to 8 bar and negative coulomb stress changes indicated by the blue lobe with a value of -1 to -8 bar. The results of the analysis of b-value and coulomb stress showed that the b-value obtained was relatively  low and correlated with a high level of change in coulomb stress. In general, earthquake-prone areas are located in the western and eastern parts of Central Sulawesi.

Abstract

Landslide hazard mapping using a geographic information system (GIS) is essential because it helps reduce disaster risks and protects communities from their impacts. In landslide hazard mapping, scoring and weighting methods and overlay analysis help determine the level of landslide vulnerability. The research data uses several parameters, including soil type, geology, rainfall, land cover, and slope. The slope was determined based on the Digital Elevation Model Shuttle Radar Topography Mission (DEM SRTM) data. The tools used are ArcGIS v10.8 software and Microsoft Office 2019. Lebak Regency has quite a lot of rainfall, especially during the rainy season, with moderate to dry intensity ranging from 1,501-2,000 mm/year and 2,001-2,500 mm/year. Stones that are easily worn and corroded are more vulnerable. Steep slopes can increase the risk of landslides, especially in areas with slippery soil types. Land cover converted to plantations or settlements tends to be more vulnerable than untouched land. Lebak Regency consists of 3 landslides: low, medium, and high. The area of low risk is 3,854.57 ha, the medium risk area is 160,884.09 ha, and the high-risk area is 164993.60 ha. Landslide-prone areas with a predominance of landslide vulnerability are shown in low level found in Wanasalam District, with an area of 2,800.91 ha or 0.08%; moderate level is found in Cileles District, with an area of 14,001.21 ha or 0.042%, and the high level is found in Cibeber District with an area of 32,501.61 ha or 0.098%.

Abstract

Bengkulu City has a high liquefaction rate, both geologically and geophysically. This is because Bengkulu City consists of rocks in the form of sand, silt, mud, clay, coral fragments and gravel in alluvial areas (Qa) and floodplains. Terrace formation (Qat). This study aims to analyze liquefaction potential using seismic waves in Bengkulu City, resulting in a layer profile (Vs) obtained from the Vs30 soil of Bengkulu City and a classification of areas with liquefaction potential. This study was conducted using a PASI 16S-24P seismograph, a set of seismic equipment used in the study area, which obtained Vs profiles derived from 24 geophones 4 m and 8 m away from each study location. Then, the RMS error and standard deviation values were generated. The result of MASW analysis data describes the Vs and Vs30 profiles in the Bengkulu City subsoil that can be classified into soil zones. Soil results at the study site show different site classes, namely B, C, D and E. Liquefaction potential can be analyzed with Vs profiles. It shows the existence of different layers in the Bengkulu city area. It can be seen that Bengkulu City is dominated by sand and gravel, causing very high liquefaction, especially in the Surabaya area, where the Vs and Vs30 soil values have soft soil values with sensitivity values of 134.0 to 171.0 m/s. Soil classification is highly sensitive to liquefaction. The study areas of Lempuing and Rawa Makmur sub-districts generally show medium liquefaction potential, and the Teluk Sepang sub-district area shows low liquefaction potential.
