Abstract

Bangunan gedung sekolah merupakan infrastruktur dengan tingkat potensi korban jiwa yang tinggi apabila terjadi gempa bumi, sehingga penting untuk dilakukan identifikasi terhadap kerentanan strukturnya. Penelitian ini bertujuan untuk menganalisis tingkat kerentanan dan risiko seismik bangunan sekolah terhadap gempa bumi guna mendukung upaya mitigasi bencana di wilayah rawan gempa, khususnya di Kota Jayapura. Metode yang digunakan dalam studi ini adalah Rapid Visual Screening (RVS) berdasarkan FEMA P-154 dan Evaluasi Risiko Seismik, yang diterapkan pada 111 bangunan sekolah dari 40 lokasi berbeda. Faktor-faktor seperti kondisi aktual bangunan, konfigurasi geometrik, dan tahanan beban lateral menjadi penentu utama dalam perhitungan nilai kerentanan. Hasil analisis menunjukkan bahwa tipologi struktur bangunan sekolah di Kota Jayapura didominasi oleh struktur beton bertulang dengan dinding pengisi tanpa tulangan (concrete frames with unreinforced masonry infill walls). Rata-rata peluang keruntuhan struktur berdasarkan metode RVS adalah sebesar 19,63%, sedangkan evaluasi risiko seismik menunjukkan tingkat risiko sedang dengan rata-rata nilai kerentanan sebesar 1901. Ditemukan pula hubungan signifikan antara peluang keruntuhan dan tingkat risiko melalui persamaan regresi linier y = 1,09 + 3,54x. Kesimpulannya, bangunan sekolah di Kota Jayapura memiliki kerentanan struktural yang patut menjadi perhatian dalam perencanaan mitigasi risiko bencana. Implikasi dari penelitian ini menunjukkan bahwa hasil evaluasi dapat dijadikan dasar perumusan prioritas penguatan struktur bangunan sekolah guna meminimalkan risiko keruntuhan akibat gempa bumi di masa depan.

Abstract

Under Presidential Decree No. 60 of 2021, on National Priority Lakes Rescue, Lake Sentani is one of 15 priority lakes to be rescued. In the annex to the President's regulation, it is mentioned to date about 90 tons or ± 5 m/year of sediment entering Lake Sentani with a total count of 62,0679.78 tonnes/year entering lake Sentani, with a storage capacity of 1,782 billion/m3. The water supply of Lake Sentani is obtained from the supply of 14 large and small rivers. With a slope inclination between 0% - 40% of the amount of sediment transported during the rainy season causes the decline in water quality and the high erosion that occurs. This study aims to find out the impact of land-use change and the effect of sediment control buildings on the number of sediments that enter Lake Sentani. From the results of the analysis the impact of land use change before the construction of the sediment control building based on the analysis carried out by the Papua River Regional Hall the known potential sedimentation rate is of 0.6 mm/th whereas the potential sedmentation rate analysed after the existence of the building of the Sediment Controller is of 0.012 mm /year. This indicates a change in the rate of potential Sedimentation entering the lake of sentani affected by the building sediment operator. When it rains with repeated flooding Q20, Q25, Q50 and Q100 years with conditions of 1 (one) sediment control building so that it can be judged to be a very heavy erosion class with land loss of more than 280 tons/ha/years with a potential sedimentation rate thickness between 2.55 mm/years to 2.85mm/years.

Abstract

This research involves several PLN substation projects in the Maluku and Papua regions. The subject of this study consisted of 25 respondents, namely 1 Project Manager, HSE Engineer and project supervisor. The questionnaire that has been given is then analyzed using the severity index method. The results of K3 risk identification on 44 risk variable indicators with high variables are found in the categories of product purchase and control, work safety in SMK3 and monitoring standards. The highest level of K3 risk to cost performance in substation construction projects in Maluku and Papua is the specification of the purchase of goods and services, the verification system of purchased goods and services, emergency planning and recovery, and labour health monitoring. The allocation of K3 risk in substation construction projects in Maluku and Papua is the most allocated risk shared between the owner and the contractor. The most K3 risk response is by holding and partially allocating to the owner by transferring. Recommendations for mitigation of K3 risks in substation construction projects in Maluku and Papua are by preparing procedures for work steps/related documents that are jointly supervised between the owner and owner. Then it is necessary to form an organization related to K3 that will be responsible for emergencies, work accidents and monthly reporting to the local Manpower Office.

Abstract

Groundwater availability in aquifers is crucial for sustaining human settlements, particularly in Kobakma District, Central Mamberamo Regency, where clean water distribution faces significant challenges due to seasonal fluctuations and infrastructure limitations. The lack of groundwater utilization has resulted in local communities relying on rainwater as their primary water source, highlighting the necessity to identify potential groundwater sources. This research aims to determine the position and depth of aquifers in Kobakma District using the geoelectric resistivity method. By identifying subsurface conditions and geological formations, the study seeks to map groundwater availability and provide recommendations for sustainable water resource management in the region. The study employs the geoelectric resistivity method using the Schlumberger configuration to measure subsurface resistivity. Data collection was conducted across 13 test points within Kobakma District. The collected resistivity values were analyzed to interpret subsurface lithology and identify potential aquifer zones. The study primarily focuses on detecting free and confined aquifers, considering variations in rock formations, permeability, and groundwater flow dynamics. The results indicate the presence of two primary aquifer layers: a free aquifer distributed across various locations at depths ranging from 10–60 meters and a confined aquifer found at depths between 100–300 meters. Some test points showed aquifer leakage due to fault structures, influencing groundwater movement. The findings suggest that groundwater sources in the study area are unevenly distributed, requiring site-specific extraction strategies. The study provides an aquifer depth distribution map, offering critical insights for future groundwater management and well-drillin.

Abstract

There are many landslide points on the Arso-Waris National road, so it is necessary to conduct research on the potential for landslides from the physical and shear strength properties. The analysis method uses Slope/W software from GeoStudio, using the Bishop and Fellenius analysis method. The results of the study on 4 points along the Arso-Waris section, showed that with a decrease in the value of the shear strength parameter, both the cohesion value (average decrease of 69.91%) and the value of the shear angle (average decrease of 92.77%) in the reverse analysis resulted in a decrease in the value of the safety factor score by 71.5% (Bishop Method) and 71.11% (Fellenius Method). The value of the smallest (critical) safety factor is 0,498, located at point 4 KM.105+193 in combination loading, by using Fellenius method. Changes in physical properties and shear strength have the potential to reduce safety factor so that there is potential for landslides.

Abstract

This study was conducted to determine the existence of subsurface aquifers and the distribution of groundwater-surface depth in Jayawijaya Regency, Mountainous Papua Province. The background of this research is the need for optimal groundwater management in areas with high topography such as Wamena City. The method used was a geophysical survey with the Wenner-Schlumberger configuration resistivity geoelectric technique to identify the aquifer layer. Primary data was obtained through direct measurements using geoelectric devices and GPS, while secondary data was obtained from related literature. The results showed that there were free aquifers with a depth of 25-105 meters and depressed aquifers at a depth of 145-270 meters in various research locations. The distribution of this aquifer is highly dependent on local geological conditions, with the availability of groundwater quite high in some areas and minimal in other areas such as Kampung Sabulama and Wasawa. In conclusion, the resistivity geoelectric method is effective for mapping the distribution of aquifers, which can further be used as a basis for groundwater management in the study area.

Abstract

The distribution of soil in Jayapura City, especially the Youtefa Bay area, consists of three dominant soil types that then form the stratigraphy of the local soil layer, namely allifial deposits, silt silt/silt clay, and fine, uniformly grained sand. Soil conditions like this have great potential for liquefaction, especially since this area is mostly passed by fault lines that have the potential to cause earthquakes. The groundwater table factor that is very close to the surface soil is also an important factor in the occurrence of liquifaction. There are 2 ways to analyze the potential for liquifaction, namely by laboratory test and from field test data. The approach to calculating field test data is CPT (Cone Penetration Test) testing. The results obtained were the Cyclic Stress Ratio (CSR) value and the Cyclic Resistance Ratio (CRR) value obtained by simulating seismic data using an earthquake strength of 6.5 on the riter scale and a pic ground acceleration value (0.3), then based on the results of the cone penetration test (CPT)/Sondir showed a maximum value of CRR 2.88, a minimum value of 0.21, a maximum CSR value of 3.70, a minimum value of 2.25. The maximum value of FS is 0.97, the minimum value is 0.07. There are 6 points at the research location that have the potential for liquefaction (Very High), namely points S1, S2, S5, S7, S8, S10, while 3 points with medium potential (High), namely points S3, S4, S9 for those with low potential (Low) S6.
