Planning With 'Three-World Structures': A Comparative Study of Settlements in Mountain Villages
Get PDFMountain peoples’ basic understanding of the world is based on binary space concepts such as top-down, left-right, east-west, sacred-profane, and others, which form a threefold division structure that places people in the middle of their environment. Mountain settlements in several places in Indonesia that still emphasize this primitive understanding or classification are interesting to study in terms of their similarities and differences. This study aimed to compare three cases of settlements, namely Singengu Mandailing village in North Sumatra, Tenganan village in Bali, and Kampung Naga in West Java in terms of their understanding of binary space concepts that constitute this threefold division structure and their application in the planning of the community’s living environment. This study is a theoretical dialogue between the concept of binary space (bincar-bonom) in Singengu Mandailing village and two other local concepts that are similar, namely kangin-kauh (sunrise-sunset) in Tenganan village and timur-barat (east-west) in Kampung Naga. This qualitative study used data from the literature and the analysis was carried out following a qualitative descriptive research procedure. Based on previous research, each case has its own data, which the authors used to uncover differences and similarities in the binary space concepts from the three study cases. The authors employed a spatial matrix image to depict the position of each settlement element in the three cases, allowing the similarities and differences to be seen. The findings of the study show that Tenganan, Kampung Naga, and Singengu Mandailing have striking similarities in terms of addressing the middle point, namely as an axis or axis point. The difference lies in the filler elements and their value. The mountain village of Bali interprets the sacred-profane binary concept similarly to the mountain village of Mandailing, except in terms of the direction of sunrise-sunset. The settlement arrangement of Tenganan Pageringsingan village at the macro, meso, and micro scales defines the direction of the sunrise and sunset as a profane direction, whereas in Singengu village, the direction of the sunrise is a sacred direction and the direction of the sunset is a profane direction. As for the Singengu and the Naga communities, they understand the middle point to be related to the direction of the sunrise and sunset in opposite directions, so there are differences in treating certain artifacts, especially cemeteries. The binary space that influences the process of forming rural settlements in the mountains can be: (1) the physical setting due to natural/geographical conditions, (2) the cosmology and belief systems adhered to, and (3) the people’s socio-cultural life. Rural settlements in the mountains can also be said to emphasize the natural aspect of the mountains with all of their spatial shaping potential. The study’s findings further show that the local people’s understanding of their living space patterns has been carried over from previous generations to the present day. This suggests that settlement planning for local communities, particularly in mountainous areas where hereditary beliefs still exist, must be approached in a specific way. In future planning projects, different locations require different planning approaches

Photometric Stereo Method Used for Woven Fabric Density Measurement Based on 3D Surface Structure
Get PDFThe measurement of the density of woven fabrics based on the vision method has been widely developed. This study used a photometric stereo method to measure the warp and weft density of woven fabrics based on the 3D surface structure. Six 2D images of the fabric were recorded, each with a different lighting direction. The six images were then reconstructed using the unbiased photometric stereo algorithm to produce the three-dimensional surface structure. The reconstructed image was used to detect and correct the skew angle with the Hough transform. For each image, a depth profile was made toward the x-axis to get the weft curve and towards the y-axis to get the warped curve. The two depth curves were filtered using a locally weighted smoothing (LOESS) filter. This study successfully measured the density of woven fabric with an average error for warp and weft of 0.64% and 0.45%, respectively
Examining External Dose Rates in Mamuju Regency, Indonesia: A Personal Radiation Dosimetry Approach
Get PDFThis study aimed to quantify the individual external radiation exposure in Mamuju, Indonesia. A SmartRad portable personal dosimeter was utilized for this purpose, and data was collected over a period of 30 days. The findings indicate that the dose rate varies from 0.152 to 4.200 μSv/h and cumulatively ranges from 0.1 to 8.4 μSv/day based on an average measurement duration of 160 minutes. The average dose rate in areas with mineral deposits is 11.02 mSv per year. In contrast, the average effective dose in areas without radioactive mineral deposits is 2.6493 mSv per year. The annual average effective dose for individuals was measured at 6.8347 mSv. These findings imply that personal exposure to radiation among the public in Mamuju exceeds the threshold recommended by the International Commission of Radiological Protection
Quality Analysis of Telemetry Tracking and Command at Ground Stations using the Association Rule Mining Approach
Get PDFLAPAN built several remote ground stations to support the telemetry tracking and command (TTC) system for the LAPAN-A2 and LAPAN-A3 satellites. These remote ground stations are located in Kototabang/KT (West Sumatra), Biak/BK (Papua), Parepare/PR (South Sulawesi), Rumpin/RP, Rancabungur/RB (Bogor, West Java), and Svalbard/SV (Norway). Problems that often arise in the TTC process are telecommands not being sent (commands sent from the ground station to the satellite) or telemetry packages not being received (feedback on telecommands sent by the satellite to the ground station). This research attempted to calculate and analyze the quality of TTC using a data-mining approach, i.e., rule mining. The calculations were performed using five main parameters: satellite name, ground station, azimuth, altitude, and communication status. The research output consisted of a combination of remote ground station parameters that may result in a successful or failed TTC. For the LAPAN-A3 satellite at the Svalbard ground station, 19 failed communication combinations were generated with a dataset of 57,029. Communication failures occur in azimuth and elevation, i.e., areas blocked by obstacles

Get PDFAbstrak
Kondisi permukaan jalan merupakan faktor yang memengaruhi kenyamanan dan keselamatan pengendara. Sehingga perlu dilakukan pemeriksaan kondisi jalan secara berkala. Pemantauan kondisi permukaan jalan di Indonesia pada umumnya masih masih dilakukan secara konvensional. Oleh karena itu, penelitian ini bertujuan untuk menerapkan pendekatan yang lebih efisien dalam mengukur kondisi permukaan jalan dengan menggunakan sensor accelerometer dan global positioning sistem (GPS) yang terinstall pada smartphone. Penelitian ini menggunakan metode Dynamic Time Warping (DTW) untuk mengevaluasi kondisi permukaan jalan secara umum dan metode K-means clustering untuk mengidentifikasi lokasi anomali yang terdapat pada permukaan jalan. Data hasil perekaman kondisi permukaan jalan USAID dari SMA Negeri 1 Lhoknga sampai Pantai Lhokseudu di Provinsi Aceh (lebih kurang 16 kilometer) dianalisis pada penelitian ini. Hasil analisis menunjukkan bahwa bentuk topografi jalan menurun dan menanjak cenderung memiliki kondisi yang lebih buruk dibandingkan segmen jalan yang mendatar. Selain itu, hasil penelitian juga menunjukkan bahwa kawasan dengan kepadatan penduduk yang lebih rendah memiliki kondisi jalan yang kurang baik dibandingkan kawasan dengan kepadatan penduduk yang lebih tinggi. Metode DTW dan K-means clustering berpotensi untuk digunakan sebagai metode alternatif dalam mengukur kondisi permukaan jalan yang lebih hemat tenaga, waktu dan biaya jika dibandingkan dengan pemeriksaan secara konvensional.

Abstract
The condition of the road surface is a factor that affects the comfort and safety of the driver. It is necessary to examine the condition of the road on a regular basis. Monitoring of road surface conditions in Indonesia is generally still done conventionally. Therefore, this study aims to apply a more efficient approach in measuring road surface conditions using accelerometer sensors and a global positioning system (GPS) installed on a smartphone. This study employs the Dynamic Time Warping (DTW) method to evaluate general road surface conditions and the K-means clustering method to identify the location of anomalies on the road surface. Recording data of USAID road surface condition from SMA Negeri 1 Lhoknga to Lhok Seudu Beach in Aceh Province (approximately 16 kilometers) were analyzed in this study. The results of the analysis show that the topography of downhill and uphill roads tends to possess worse conditions than the horizontal road segments. In addition, the results also show that areas with lower population densities have adverse road conditions than areas with higher population densities. The DTW method and K-means clustering demonstrate the potential to be used as an alternative method in measuring road surface conditions which is more efficient in energy, time and cost when compared to conventional inspection.

Kinerja Mekanistik Campuran Beraspal dengan Mensubstitusi Agregat Kasar dengan Batu Vulkanik Merah
Get PDFAbstract
The increasingly limited availability of volcanic stone in nature has caused road pavement construction materials to use black volcanic stone mixed with red volcanic stone, which is lighter in density and porous. This research aims to analyze the mechanistic performance of asphalt mixtures by substituting coarse aggregate with red volcanic stone up to a percentage of 10% at a granule size of ½", 3/8", No. 4 according to conditions in the field. The asphalt mixture is made using the marshall method. Mechanistic characteristics are obtained from indirect tensile stiffness modulus (ITSM) testing according to BS EN 12697-26: 2012, dynamic creep testing (BS EN 12697–25:2005) and indirect tensile fatigue testing (ITFT) according to BS EN 12697–24:2012 using a dynapave universal testing material (UTM) 30 test tool. The marshall characteristic values of the asphalt mixture meet the specifications of the Ministry of PUPR (2020), the stiffness characteristic increases by an average of 6.9 % for each additional substitution of 5% red volcanic stone. Deformation resistance increases with typical values of creep slope, concluding that asphalt mixtures can be used for heavy traffic loads (ESA >106). The fatigue resistance characteristics are lower (earlier to collapse) compared to without red volcanic stone substitution and there is a decrease in fatigue resistance of 2.18% for each additional 5% red volcanic stone substitution.
