Abstract

The Indonesia Weda Bay Industrial Park (IWIP) has rapidly transformed Central Weda District’s spatial structure between 2012 and 2022. This paper integrates satellite-based land-use change analysis, regional statistics, spatial plan (RTRW/RDTR) review, field survey summaries, and carrying-capacity computations to evaluate the impacts of industrial agglomeration on land conversion, housing pressure, tenure dynamics, and ecological buffer integrity. Results (from local datasets) show settlements increased from 39.3 ha (2012) to 82.2 ha (2022), while industrial area expanded to 16,000 ha. Industrial employment rose from 650 (2018) to 29,800 (2022), fueling a nearly 400% increase in local land prices (e.g., Lelilef Sawai: IDR 50,000/m² - IDR 277,000/m²). Carrying capacity calculations indicate most villages retain DDPm 1 (sufficient capacity) except Lelilef Sawai (DDPm 1), which already exceeds sustainable settlement thresholds. The paper concludes with policy recommendations for zoning enforcement, ecological buffer protection, worker housing programs, and integrated industrial-regional planning.

Abstract

Universitas Gadjah Mada (UGM) berupaya mewujudkan kampus Educopolis dengan menyediakan sistem transportasi yang kondusif bagi Kawasan kampus UGM. Penyediaan infrastruktur jalan yang aman bagi pengendara sepeda motor merupakan salah satu upaya untuk mencapai tujuan tersebut. Penelitian ini bertujuan untuk menganalisis risiko keselamatan dari aspek pengendara sepeda motor terhadap jaringan jalan di Kampus UGM. Metode yang digunakan adalah pemeringkatan bintang (star rating) yang dikembangkan oleh International Road Assessment Programme (iRAP). Hasil penelitian menunjukkan bahwa lebih dari separuh ruas jalan (53%) memiliki Star Rating 3, dan sebagian besar persimpangan dan jalan pendekat (92%) memiliki Star Rating 1. Kondisi keselamatan jalan, yang ditunjukkan oleh star rating dan star rating score ruas jalan dan persimpangan, memiliki hubungan yang kontradiktif dengan jumlah kecelakaan yang terjadi di lokasi analisis. Hubungan antara star rating score dengan kondisi jalan penyebab risiko tipe kecelakaan dominan menunjukkan bahwa kondisi jalan yang menyebabkan kecelakaan run-off sisi pengemudi (run-off-driver side) memiliki nilai paling besar.

Abstract

Disaster risk reduction is an effort that can be made by various parties to reduce the negative impacts that occur when a disaster occurs. This can be done in various facilities and infrastructure both in cities and villages, including in housing or residential homes.This study aims to evaluate the resilience of Fala Kanci buildings in Ternate with an assessment method based on standards issued by the government and analyzed with building resilience standards according to the type of construction, material, design and function of the building.The Fala Kanci studied were those that had been processed and reused not only as housing or had been utilized as buildings with mixed functions between housing and commercial or social functions.

Abstract

Massa batuan merupakan batuan utuh yang dipisahkan oleh struktur geologi seoerti kekar, sesar, perlipatan dan sebaginya. Kemampugalian merupakan kemampuan massa batuan untuk digali menggunakan alat gali mekanis maupun peledakan. Penentuan kriteria kemampugalian massa batuan andesit pada penelitian ini menggunakan metode Geological Strength Index (GSI) yang dipublikasikan oleh Marinos dan Hoek (2000). GSI merupakan metode empiris dengan memperhitungkan faktor peringkat struktur/structure rating dan peringkat kondisi permukaan/surface condition rating. Berdasarkan hasil analisis diperoleh kriteria kemampugalian pada massa batuan Andesite Massive (AM) dengan nilai GSI Index 70 (S2D1), GSI 73 (S2D1) dan Point Load Index sebesar 2.795 MPa adalah peledakan/blasting.  Serta GSI 61 (S3D2), dan Point Load Index sebesar 2.795 MPa adalah pemukul/hammer. Kriteria kemampugalian pada massa batuan Andesite Fracture (AF) dengan nilai Nilai GSI 40-48 (S4D1 – S5D1) dan Point Load Index sebesar 2.131 MPa adalah penggaruan/ripping serta nilai GSI 29 (S5D3) adalah penggalian/digging.

Abstract

Groundwater is a vital resource for irrigation, industry and drinking water, yet its widespread utilization is causing shortages in many areas. Therefore, it is important to maintain and protect groundwater resources for their sustainability. One way to monitor groundwater pollution is by using geoelectric methods. This study aims to analyze underground water pollution around the Balibunga Rum Landfill and model leachate water flow using geoelectric methods. This quantitative study collected resistivity data on the first pass, which showed resistivity values ranging from 12.5 - 80.7 Ωm to 3366 - 8555 Ωm at a depth of 1.25 m to 19.78m. From the analysis, pollution due to leachate seepage into the ground was identified. The movement of this contamination is towards the area with the lowest elevation, indicating contamination of the groundwater around the landfill.

Abstract

PT Putra Mekongga Sejahtera is a nickel laterite mining company located in Pomalaa District, Kolaka Regency, Southeast Sulawesi Province. In a mining activity, many factors affect the aspects of production achievement, one of which is the haul road. Haul roads make a major contribution to smooth transportation operations if the road geometry is in accordance with the dimensions of the conveyance used, then the production target of 80,000 tons / month can be achieved. The current field conditions in terms of road geometry are considered unrepresentative for the movement of hauling equipment and can interfere with mining activities. Based on actual haul road geometric measurements between 5.41-16.98 meters while the theoretical road width for straight roads is 8.72 meters. The actual bend road width ranges from 5.50-15.10 meters while the theoretical bend road width is 14.32 meters. The actual road slope ranges from 0.35% to 17.30% while the maximum road slope is 12%. After evaluation, there are 4 straight road segments that need to be increased in width, namely segments AB, BC, CD and DE and 5 segments of bend road width, namely segments AB, BC, CD, DE and EF, as well as grade reduction in segments AB, BC, DE and EF. Hino FM 260 JD dump truck production before road geometry improvement is 3029 tons/day or 78761.75 tons/month. Hino FM 260 JD dump truck production after ideal road geometry improvement is 3143 tons/day or 81724.38 tons/month.

Abstract

Slope stability is a fairly broad field, considering that of the several types of geotechnicalconstruction failures, the largest is slope stability failure. Of the several types of natural disasters that occur in Indonesia, floods and landslides are at the top of the list of victims. The aim of this research is to examine the characteristics of based-plate anchor systems with and without geotextiles. The basic concept of an anchored geosynthetic system is to increase compression in the soil under the geosynthetic by driving the anchor to a certain depth. With additional compression on the soil, soil compaction will occur so that the frictional strength of the soil increases. The research carried out included testing in the laboratory. This research will be carried out at the Soil Mechanics Laboratory of the Civil Engineering Department of Hasanuddin University, Makassar. The sample is disturbed soil originating from the location in front of the Laboratory of the Faculty of Engineering, Hasanuddin University, Makassar, South Sulawesi. The relationship between based-plate geometry and load for a tensile load of 2500 kg and a decrease in soil deformation of 0.18 cm. Based on research conducted with a geotextile distance of 15 cm per layer, it can increase tensile strength and reduce the settlement that occurs. An increase in the anchor tensile load results in an increase in soil deformation.

Abstract

At this time the development of technology is rapid that there are many tools facilitate human work, one of which is to detect the freshness of fish. In Indonesia alone there are many types of fish consumption derived from sea water and fresh water. Fish consumtion in Indonesia increased every year by an average of 3% based on statistics from the Ministry of Fisheries and Marine Affairs from 2014-2019.  The system designed in this study uses color sensors and odor sensors that serve to detect the freshness of fish. The microcontroller used is arduino nano which serve to process programs that have been designed. The study used TCS-3200 and MQ-135 sensors as inputs that were then processed in the Arduino Nano which was then displayed on the LCD. Tets on this study used catfish as objects. Catfish will be classified into two, namely fresh and not fresh. The worse the quality of the fish, the greater the PPM value. The error rate in this study is quite large at 7,1.
