Abstract

Abstract Based on a survey conducted by BPS, it is known that in West Sumatra province the city with the highest poverty rate is the city of Padang. Poverty in Padang City experienced an increase in 2021 and then decreased in 2022. To see the relationship between factors that influence poverty in Padang City, the spatial regression method was used by paying attention to spatial dependence. This research aims to determine several factors that can influence poverty in Padang City. The results of the research show that the factors that can influence poverty in Padang City in each sub-district are the number of public health service facilities (X1), the distance of the sub-district from the city center (X3), and population density (X4).

Abstract

Iron sand generally contains minerals such as ilmenite, magnetite, and hematite. Based on the results of previous tests, the main composition of iron sand in Rhee, Sumbawa regency, is magnetite. One method to increase the Fe content in iron sand is by pre-treatment with NaOH. NaOH is also used to precipitate heavy metals in a mineral. In this study, three variations were carried out with the ratio of NaOH: iron sand, namely: 1: 4, 2: 4, and 3: 4 at a temperature of 300 C. Furthermore, the calcination results were followed by the synthesis of Fe3O4 nanoparticles using the coprecipitation method. The results of the XRF characterization showed an increase in Fe levels after being processed by the alkalization treatment. The highest concentration was obtained in 1:4, with a Fe percentage of 91.1%. The results of the XRD characterization showed that the synthesis of Fe3O4 was successfully carried out with single phase Fe3O4 amlording to the data reference 96-9005839 forms and the space group F d -3 m. Crystal size analysis Using the Debey-Scherrer equation, the respective sizes were 12.7 nm, 8.71 nm, and 9.76 nm, respectively.

Abstract

Penelitian ini bertujuan untuk mengetahui laju konversi lahan sawah di Kota Padang dan menganalisis kebutuhan konsumsi serta ketersediaan produksi beras. Penelitian menggunakan pendekatan kuantitatif dengan metode analisis deskriptif berbasis data sekunder. Data penggunaan lahan diperoleh dari citra satelit Landsat tahun 2010, 2015, 2020, dan 2025 yang dianalisis menggunakan kombinasi Object-Based Image Analysis (OBIA) dan klasifikasi terbimbing. Sementara itu, data produksi beras, jumlah penduduk, dan konsumsi beras bersumber dari Badan Pusat Statistik dan dianalisis untuk menghitung ketersediaan, kebutuhan, serta rasio ketersediaan beras. Hasil penelitian menunjukkan bahwa selama periode 2010–2025 terjadi konversi lahan sawah yang signifikan, terutama menjadi kawasan terbangun, meskipun sebagian besar sawah masih mampu mempertahankan fungsinya. Ketersediaan beras Kota Padang pada periode 2020–2024 cenderung menurun dan berfluktuasi, seiring dengan berkurangnya produksi lokal, sementara kebutuhan konsumsi beras relatif stabil. Analisis kesesuaian lahan menunjukkan bahwa lahan potensial LP2B didominasi oleh kelas S2 dan S3, dengan keterbatasan lahan kelas S1. Temuan ini menegaskan pentingnya pengendalian konversi lahan sawah serta perlindungan lahan potensial LP2B guna menjaga keberlanjutan ketahanan pangan Kota Padang.

Abstract

The presence of UIN III Imam Bonjol Campus in Balai Gadang Subdistrict has had a significant impact on the development of its surrounding area, particularly in terms of socioeconomic and educational aspects. This study aims to examine the physical spatial development of the area around the campus and its influence on the local community's socioeconomic and educational conditions. The research employs a quantitative approach with a descriptive-analytical method and spatial analysis techniques. The analysis process involves the application of the Generate Tesselation: H3 Hexagon method by converting the administrative shapefile data of Padang City into hexagon forms to produce more proportional and analyzable data. Development data from 2012 and 2022 were used for validation and visualization of spatial growth dynamics. The results indicate rapid physical development around the campus, marked by an increase in housing, business establishments, and supporting infrastructure. This development has directly contributed to increased economic activity and improved access to education for the local population. Although spatial deviations were observed in some areas, data validity remains high. The study concludes that the presence of the campus acts as a catalyst for spatial transformation while promoting improvements in the socioeconomic welfare of the surrounding community.

Abstract

The conventional Land and Building Tax (PBB) evaluation methods in Indonesia, namely in Baso District, Agam Regency, depend on two-dimensional measures with accuracy rates ranging from 85% to 95%, resulting in possible revenue deficits and assessment inconsistencies. This work seeks to create and execute a more precise tax assessment system utilizing high-resolution 3D spatial data obtained by UAV-LiDAR technology. The study utilizes a quantitative applied methodology, employing a DJI Matrice 350 RTK outfitted with LiDAR sensors for data acquisition. Data processing with DJI Terra and TerraSolid software produces Digital Terrain Models (DTM) and Digital Surface Models (DSM), facilitating accurate land boundary delineation and 3D building digitization. The findings indicate a substantial enhancement in spatial measuring accuracy, attaining 97-99% precision relative to traditional approaches. The implementation facilitates thorough property evaluation via precise measurements of building heights, volumes, and land areas, thereby offering a more dependable foundation for tax computations. The study suggests that, despite constraints including elevated initial costs and training demands, the inclusion of UAV-LiDAR technology significantly improves the accuracy, efficiency, and transparency of PBB assessments, representing a notable improvement in contemporary property tax administration systems.

Abstract

The uneven availability of telecommunications networks is a serious problem for the community in Sangir Batang Hari District, as it limits access in the field of information and communication. This research is intended to conduct an analytical assessment of the coverage of telecommunication towers and determine the optimal location for the construction of new towers to support equitable communication services in the region using location allocation methods and simulations with Atoll software. The main parameters analyzed include RSRP (Reference Signal Received Power) values, topography, land use, and population distribution. The validation of the modeling results was collected through measurements along the main road using the G-NetTrack Pro application, which obtained actual signal strength data from 2.815 samples. The modeling results using Atoll software show that coverage with excellent quality (-70 dBm) covers an area of approximately 22,125 m². Good quality (-80 dBm) covers an area of approximately 152,900 m². Normal quality (-90 dBm) covers an area of 14,406,321.92 m². Meanwhile, poor quality (-100 dBm) covers an area of approximately 378,163,410.4 m² and very poor quality (
