Abstract

In 2020, a research team conducted XRD analysis of the sand from Mandangin Island, Sampang Regency. The results showed that the sand contained a CaCO3 phase of over 90%, while the XRF analysis revealed that 94% of the minerals in the sand were Ca. Two years later, in 2022, the same team conducted a compression test on concrete mixed with CaCO3 sand, and the highest value they obtained was 22.68 MPa. However, they found that further research is needed to optimize the use of CaCO3, rice husks, and cement in concrete production and to maximize the potential of this natural material. To achieve this, they ground the rice husks to a fine powder and filtered them using a 200 mesh and 300 mesh sieve, while also varying the mixture ratios of rice husks : CaCO3 sand : and cement. The XRF results of the mineral content of rice husk ash showed that it contained 84% Si. In terms of compressive strength, the highest value of 27.2 MPa was achieved by using a ratio of 0.5:1:1.5 for rice husk ash, sand, and cement, respectively. The team also found that the smaller the filter used, the higher the compressive strength test results, with the 300 mesh filter producing the highest value of 13.6 MPa.

Abstract

In the Talang siring tour of the Pamekasan district, numerous illegal mining operations along the coast for sale and personal use produce building materials with low economic value. However, if the sand is processed further, it will produce materials with high technology utilization and economic value. This research is a preliminary investigation into converting sand into high-value minerals to be utilized economically. Using X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD) experiments, this study aims to determine the sand's mineral content in the Talang Siring tourist area in Pamekasan Regency. Initial identification is the XRF test function for analyzing sand's chemical elements and composition. The purpose of XRD is to analyze the crystal structure and correlate the results with Macth and origin software based on the XRF results. The results of the XRF test indicated that Silicone had the highest concentration of minerals at 63.8%, followed by Calcium at 29.4% and Iron at 2.45%. The XRD test results indicated that the sand's mineral composition was qualitatively SiO2 90%, CaCO3 8%, Iron 1%, and the remainder 1%.

Abstract

Salah satu kecamatan di Pamekasan adalah Kecamatan Batumarmar (Mitra), pada Kecamatan Batumarmar terdapat 3 desa yang merupakan desa kekeringan yaitu bujur timur, bujur barat dan bujur tengah. Ketiga desa tersebut sangat kekurangan air, contohnya pada saat mandi masyarakat yang berada di 3 desa tersebut mandi di sungai yang jaraknya kurang lebih 1 kilometer. Untuk mandi saja membutuhkan perjalanan yang melelahkan. Masyarakat ini juga mencuci pakaian atau ternaknya di sungai ini. Bahkan untuk kebutuhan minum saja ketiga desa tersebut membeli dengan trek tangki ukuran besar sehingga bisa menimbun air yang cukup panjang. Tujuan Tim PKM mengatasi kekeringan dengan menggunakan sistem sanitasi, biopori dan hidroponik untuk menimbun air. Dengan adanya sistem ini diharapkan bisa membantu permasalahan diatas. Sistem ini bisa memaksimalkan penimbunan air bahkan dengan menggunakan hidroponik pakan ternak bisa tumbuh dengan lebat. Hasil yang didapat dalam pengabdian ini adalah perubahan pola pemikiran masyarakat untuk menimbun air serta ketersediaan air didalam tanah melimpah.

Abstract

Landslide zone investigation has been conducted using geoelectricity to determine the number of cracks and using a compressive strength test to determine compressive strength cracks. The result of this research is that the rock layers of Waru District consist of soil layers resulting from the weathering of quartz rock into quartz sandstone. This quartz sandstone lies on top of a more solid rock layer. The type of landslide that is formed in the Waru sub-district is translational. This type of landslide is caused by water entering the lower layer, causing landslides and the number of cracks that trigger landslides. The results of the low compressive strength test resulted in landslides. This result was due to a decrease in the number of pores filled with water and an increase in the pores that were not filled with water. This occurs due to the presence of water in the cracks, the number of cracks cavities, and the density of the cracks which results in reduced adhesion between the cracks holding layers.

Abstract

The results of this study are the factors of landslides there are many cracks in the ground, normal faults, shear faults and slope of the soil surface. The higher the slope of the land surface, the more potential for landslides. Results of XRF Waru 1 Si 58.3%, Waru 2 Ca 71.37%, Waru 3 Si 43.3%. The results of XRD Waru 1 and Waru 2 were 88% SiO2 compound, Waru 3 in the form of CaCo3 compound was 75.2%. SEM results with 10,000x enlargement Waru 1 is almost homogeneous in the form of slabs which identifies an uneven grain size and with a little porosity indicating the sample is partially amorphous in structure, Waru 2 shows an inhomogeneous sample with a fairly high porous dispersion and is not equally, Waru 3 shows the existence of an almost cube crystal form with high porosity so that it causes frequent landslides due to the density of a sand is still lacking so that it makes it easy for the land to be evicted because there are still many cavities in the soil.
