Abstract

Tujuan dari pengabdian adalah mengetahui Tingkat intensitas longsor di sepanjang jalan Lenangguar – Lunyuk dan mengetahui kelengkapan fasilitas kesehatan serta kesiapan Puskesmas Lenangguar dalam menangani korban akibat bencana longsor sehingga dapat meminimalisir risiko bencana Longsor. Pengabdian ini terdiri dari empat tahap, yaitu: Studi literatur digunakan sebagai acuan dasar untuk memperkuat latar belakang dalam pengabdian ini, penentuan intensitas longsor di sepanjang Jalan Lenangguar – Lunyuk, wawancara Kepala Puskesmas Lenangguar dan salah satu Dokter yang bertugas untuk mengetahui Tingkat fasilitas dan jumlah tenaga medis di Puskesmas Lenangguar, sosialisasi intensitas longsor, kesiapan dan kelengkapan puskesmas lenangguar dalam menghadapi bencana longsor kepada Kepala Desa Lenangguar untuk pemberitahuan kepada Masyarakat. Puskesmas Lenangguar hanya memiliki 2 Dokter, 12 Perawat, 1 Ambulan, Obat-obatan cukup terbatas, dan juga keterbatasan alat-alat medis sehingga hanya bisa menangani luka-luka lecet. Intensitas longsor yang cukup banyak dan sering terjadi saat musim hujan di Jalan Lintas Lenangguar – Lunyuk sehingga Puskesmas Lenangguar direkomendasikan untuk meningkatkan fasilitas sehehatan, tim medis, melakukan pelatihan manajemen bencana dan disaster plan sehingga mengurangi risiko bencana longsor dan meningkatkan ketahanan masyarakat dalam menghadapi bencana.

Abstract

The Kolaka-Kolaka Timur road section serves as a vital connection among several districts in Southeast Sulawesi. This region is particularly susceptible to landslides during the rainy season, resulting in the road being obstructed by landslide debris. The objective of this research is to assess the thickness of the weathered layer, a critical factor contributing to landslides, as part of efforts aimed at mitigating such events. The research employs the resistivity geoelectric method utilizing a Wenner configuration with five passes. The electrode spacing is set at 7 meters, covering a total track length of 105 meters. Analysis of the measurement results indicates that the weathered layer across each track comprises alluvial deposits originating from the weathering of Sekis rocks, characterized by a resistivity of less than 20 Ωm. The thickness of the weathered layer varies across the tracks: Track 1 exhibits a thickness ranging from 4 to 12 meters, Track 2 ranges from 1 to 10 meters, Track 4 varies from 0 to 8 meters, and Track 5 shows a thickness between 0 and 10 meters.

Abstract

Semakin meningkatnya permintaan akan bahan material ramah lingkungan untuk mengurangi dampak negatif terhadap kualitas udara global, kesehatan dan iklim global. Beberapa peneliti mulai fokus pada komposit berbasis biokomposit. Komposit dari serat alam dan partikel alam merupakan salah satu alternatif untuk komposit polimer karena keunggulannya dibandingkan dengan serat sintetis. Pada penelitian ini fraksi volume yang digunakan antara serat sisal dan serbuk kayu jati yaitu 5% serat : 15% partikel, 10% serat : 10% partikel, dan 15% serat : 5% partikel dengan volume resin tetap yaitu 80% menggunakan standar ASTM untuk uji bending dan uji tarik. Dari pengujian yang dilakukan, akan didapatkan beberapa data hasil pengujiam, nilai uji bending yaitu MOE teringgi pada variasi 15% serat : 5% partikel dengan nilai 6334,67 MPa dan nilai MOR sebesar 98,21 MPa diikuti dengan hasil terrendah pada variasi 5% serat : 15% partikel dengan nilai MOE sebesar 3987,13 MPa dan nilai MOR sebesar 68,19 MPa. Pada uji tarik didapatkan hasil tertinggi pada variasi 15% serat : 5% partikel dengan nilai nilai tegangan sebesar 71,36 MPa, regangan sebesar 1,61%, dan modulus elastisitas memperoleh nilai sebesar 44,31 GPa, pada variasi 10% serat : 10% partikel diperoleh hasil uji tarik terendah nilai tegangan 50,26 MPa, regangan sebesar 1,34%, dan modulus elastisitas sebesar 37,56 GPa. Hasil dari pengujian menunjukkan bahwa semakin meningkatnya fraksi volume serat membuat kekuakatan mekanik komposit semakin tinggi, penambahan serbuk kayu sebagai campuran filler komposit berfungsi untuk mengisi kekosongan pada pada selah-selah serat dan matriks saat proses pembuatan komposit.

Abstract

The strength of the mechanical and physical properties of particle composite materials is influenced by the volume fraction of the powder and matrix. Fraction variations used are 30:70%, 50:50%, and 70:30% with the hand lay up method. The pretreatment was carried out by soaking 2% NaOH for 1 hour. The results of the MOE treatment mechanical test received the highest test value at the powder volume fraction of 30:70%, which was 6145.51 kgf/cm² and the highest MOR test value at the 30:70% volume fraction, which was 167.38 kgf/cm². Meanwhile, the highest non-treatment MOE value at the 30:70% powder volume fraction was 5540.9 kgf/cm² and the highest MOR test value at the 30:70% volume fraction was 156.6 kgf/cm². The results of the physical properties test were the highest density at the 30:70% powder volume fraction of 0.87 gr/cm³ and the highest density at the 30:70% non-treatment powder volume fraction of 0.78 gr/cm³. The results of the MOE mechanical test do not meet the JIS A 5908-2003 standard while the MOR mechanical test and physical test have met the JIS A 5908- 2003 standard. The results of microstructure testing showed that at a fraction of powder volume of 30:70% it was seen that the particles were coarser which blended perfectly with the matrix. Meanwhile, in the volume fraction of non-treatment powder 30:70% it looks finer particles and powders with a matrix seem to not glue well, this is because of the wax coating on the powder.

Abstract

The aim of this study is to create a descriptive model of environment-based reclamation recommendations for ex-mining land in the Sumbawa region that is easy to understand and consider. This research consisted of three stages: literature studies from previous researchers were used as a basic reference to strengthen the background and discussion in the research, especially with regard to environment-based reclamation engineering, mapping of open hole points from former community mining, and environment-based reclamation recommendation models. well and precisely in the corn plantation while still considering the initial shape of the topography. Effective reclamation to restore agricultural land damaged and with holes caused by mining without permits by providing recommendations in the form of a descriptive model includes backfilling of openings, planting trees, or revegetation, considering it for agrotourism, and economical fish-farming ponds.

Abstract

income for the local community, also have negative impacts, namely land degradation with numerous abandoned and poorly managed former mining holes. This research aims to provide practical and sustainable recommendations for adaptive reclamation activities in former artisanal mining areas in Area Y, and to serve as a guide for realizing more responsible and sustainable artisanal mining practices. The research was conducted using a qualitative method through the analysis of relevant secondary data. The study results indicate that miners tend to leave former mining holes unreclaimed. This is due to miners' limitations in both technical knowledge and capital, rendering them incapable of carrying out reclamation independently. The impact of these abandoned mining holes has the potential to become a future hazard. The selection of an adaptive land reclamation model focusing on a flexible and participatory approach has proven to be an effective and efficient method for implementing reclamation activities in artisanal mining. Both government and non-governmental agencies can conduct intensive education and training to maximize local community participation for the success of reclamation activities
