Abstract

Has done research on different container and the syringe bulb to determine the number of moles of air. If the gas or air is introduced into the syringe or bulb then the more air is forced into it. The analysis uses Boyle-Mariotte law shows that the number of moles of air in the syringe with constant temperature and number of moles of air at constant volume is a sphere with eqqual 0.02 mol. Thus two different media (cylindrical and spherical), giving the same number of moles. Obtaining the number of moles show that the application of Boyle-Mariotte is derived from the ideal gas law is appropriate.

Abstract

Observation of the stress and strain in materials steel, brass and anneal is done by testing to determine the tensile modulus of elasticity of the material. The results showed that the modulus of elasticity of the material brass is smaller than the brass alloy steel and steel materials, caused by the formation of the composition of the material is different. The relationship between stress and strain are used to gain slope value, and this value used to determine the modulus of elasticity of steel materials, brass and anneal. The analysis showed that the magnitude of the modulus of elasticity of brass material brass=(20.10  1.60) x109 Pa, anneal materials anneal=(68.10  2.20) x109 Pa, and steel materials steel=(201, 00  5.30) x109 Pa. The results of tensile tests conducted on all three materials can be used to determine the comparative figures Poisson. The analysis showed the amount of comparative figures in steel material Poisson msteel=0.106  0.002, brass material mbrass=0.104  0.002 and anneal materials manneal=0.103  0.005. Figures Poisson appeal on steel materials is greater than the brass and anneal

Abstract

Kegagalan lereng yang terjadi pada suatu lereng memiliki bidang gelincir pada struktur bawah permukaan sehingga dapat menimbulkan bencana longsor. Bencana ini terjadi di lokasi penelitian karena berada disekitar jalur patahan sehingga sebagian tanah mengalami retak dan longsor, karena disebabkan oleh hujan dengan durasi beberapa jam, sehingga tanah menjadi jenuh dan terlepas menggelincir mengikuti lereng dengan kecepatan yang tinggi dan panjang larian yang semakin jauh sampai mengendap. Hal inilah yang menyebabkan kerusakan dan kerugian, korban jiwa, pengungsian dan kerusakan lingkungan. Penelitian ini dilakukan di longsor Booi untuk menjelaskan perumusan model fisika dalam menentukan kecepatan dan panjang larian longsor menggunakan hukum kesetimbangan energi mekanik berdasarkan pada model lumped mass. Hasil analisis memberikan estimasi kecepatan maksimum 13.3 m/s pada posisi 33.0 m berada pada elevasi 96.2 m.dpl dan panjang larian longsor 102.2 m. Dengan demikian, semakin besar sudut kemiringan lereng terhadap sudut gesekan maka kecepatan longsor semakin tinggi dan panjang larian semakin besar. Alterasi kecepatan longsor sangat tergantung pada elevasi lereng dan jangkauan pengendapan material longsor.

Abstract

Research of the Block V Wayame Ambon slide planes has been carried out using the geoelectric resissivity method of the Wenner-Schlumberger configuration. The purpose of the study was to estimate the structure of the subsurface rock layer and identify the distribution of slide plane based on the cross section of rock resistivity. The rock resistivity modeling results show the existence of a slip zone on both measurement trajectories. On the Line-1 it was assumed that two slide planes found at a depth of 2.0 m located at a distance of 6.0 m and 38.0 m, while on the Line-2 the slide planes are in 2.5 m depth is located at a distance of 28.0 m. The slip zone which is a landslide-prone area lies in the intermediate resistivity group (30-70 W.m) with the type of sand or clay sand which overlaps the high resistivity group (> 70 W.m) in the form of a hard claystone (bedrock). Landslide-prone zones can have the potential for a subsequent landslide to occur by allowing the potential spread of landslides to remain at their original location in the event of disturbances on the slopes and the opportunity to shift towards the top of the slope.

Abstract

Climate change has triggered increased rainfall intensity and exacerbated the risk of disasters, especially landslides in the tropical hilly areas of Ambon Island. This community service activity was carried out in Karang Panjang Village, Sirimau District, Ambon City, to increase public awareness and knowledge about the impacts of climate change and preventive strategies for slope landslides. Activities include geoscience and bioengineering-based education and direct practice of planting vetiver grass (Chrysopogon zizanioides) as a natural solution for slope prevention. The evaluation results showed an increase in public understanding by 24.7% after participating in a series of socialization activities. In addition to gaining knowledge about the causes and dynamics of slope stability, residents were also equipped with skills to plant and maintain vetiver independently and sustainably. This program proves that an educational and participatory approach can be a strong foundation for community-based disaster mitigation.

Abstract

In situ measurements of hydrophysical parameters have been carried out in groundwater in dug wells, drilled wells, and reservoirs related to temperature, electrical conductivity, degree of acidity, salinity, and total dissolved solids (TDS). This study aims to analyze the characteristics of hydrophysical parameters in water samples and create a water quality distribution model based on hydrophysical data in the study area. The results showed that water zoning based on air temperature and water temperature is included in the mesothermal zone category, and this zone water may originate from free/leaking aquifers. The results of hydrophysical parameter measurements were TDS with a concentration value of < 1000 mg/L, conductivity parameter (s) with a concentration value of s < 2500 mS/cm, a pH parameter ranging from 7, and a salinity parameter with a concentration value < 1000 ppm which is allowed according to water quality standards which are found in dug wells (old wells, SGM-3), drilled wells (SBM) and pond (Em). While the hydrophysical parameters for measuring other groundwater samples are not in accordance with water quality standards. Modeling the distribution of water quality based on three hydrophysical parameters (TDS, s, and S) in the study area shows a shallow groundwater pattern and seawater intrusion has occurred in several wells (SGM-1, SGM-2, and SGM-4). The distribution of TDS, s, and S concentration values at study sites varies with distance from the coastline and topography.

Abstract

Belis Village is located in the Waru basin adjacent to the Bula basin on the eastern part of Seram Island and has potential shallow hydrocarbon manifestations. This research aims to determine the mineralogical characteristics of the rocks that make up shallow hydrocarbon manifestations at the research location. The research method used is physical analysis of minerals including petrographic analysis and XRD methods. The analysis results of the XRD method show an abundance of quartz minerals at 58%, followed by clay minerals at 35%, opaque minerals at 25%, and the rest in the form of cavities while feldspar minerals are secondary minerals. The results of the XRD analysis show that the more dominant mineral is protoenstatite (MgSio3) with an average abundance of 70.33% as a carrier of shallow hydrocarbon seeps, Quartz (SiO2) with an average abundance of 18.46%, and Clinoestatite with an average abundance of 11.21% as a mineral associated with shallow hydrocarbon seeps.

Abstract

Groundwater has a wider distribution than surface water because groundwater fills all the pores of the rocks and soil beneath the earth's surface. Groundwater is located in a layer of soil called the aquifer layer which can be identified by the resistivity geoelectric method. The hydrogeological survey conducted in this study included the characterization of aquifers such as rock types and aquifer types through the interpretation of subsurface conditions using the geoelectric resistivity mapping (LEM) method with the Wenner-Schlumberger configuration and sounding (VES) with the Schlumberger configuration. The results showed that the MarselaVes-1 (GeoM-01), MarselaVes-2 (GeoM-02), and BululoraVes-1 (GeoB-01) point areas have local aquifers with moderate productivity and wide distribution. These three geoelectric points have the potential for drilling. Meanwhile, the hydrogeology at the BululoraVes-2 (GeoB-2) point has an aquifer with low productivity.
