Abstract

Health remains one of the most important aspects of every human life, with access to quality healthcare services being a pivotal component of human well-being. In Indonesia, health facility distribution has been characterized by disparities, primarily concentrated on the populous Java Island. This distribution inequity underscores a significant challenge in achieving Sustainable Development Goals (SDGs) under Goal 3, which aims to ensure healthy lives and promote well-being for all. Bandar Lampung, the most densely populated city in Lampung Province and one of Sumatra's most populated cities, experiences an intensified demand for healthcare facilities due to its substantial population. However, the city grapples with numerous infrastructural challenges, including suboptimal road conditions that hinder accessibility to essential healthcare services. These challenges further underscore the urgency of assessing and addressing the healthcare infrastructure within Bandar Lampung. This research seeks to undertake a comprehensive evaluation of health facility availability in Bandar Lampung City, as well as an in-depth analysis of the accessibility of healthcare services in different areas of the city. To achieve this, the study employs the Network Analysis Tool, which leverages road network data to model travel distances and times. In addition to road network data, geospatial population data sourced is integrated into the analysis to gauge the demand for healthcare facilities within Bandar Lampung. This multifaceted approach is essential in comprehensively addressing the complex interplay between supply and demand in the healthcare sector. The combination of these datasets culminates in the creation of an accessibility model that unveils the disparities in healthcare access across Bandar Lampung. The model highlights areas where accessibility to healthcare facilities remains surprisingly low, despite the city's high population density. Conversely, it also identifies regions with high accessibility, potentially serving as templates for improving healthcare distribution in underserved areas. By revealing these disparities, this research contributes valuable insights to healthcare planning and policy formulation in Bandar Lampung and offers a template for addressing similar challenges in other regions with uneven healthcare distribution.

Abstract

Indonesia is one of the countries prone to earthquakes with significant damage. An area that is frequently hit by earthquakes is Sumatra Island. Several cities, such as Banda Aceh City and Sibolga City on Sumatra Island, quite often experience tremors. For this reason, mitigation efforts are needed through earthquake insurance in managing disaster risk in earthquake-prone areas such as Banda Aceh City and Sibolga City so that it can reduce the impact caused by earthquake disasters. This research aims to determine the probability of an earthquake occurring in Banda Aceh City and Sibolga City using the Probabilistic Seismic Hazard Analysis (PSHA) method. Apart from that, this research also aims to determine the value of the building damage ratio and the estimated value of pure earthquake insurance premiums in Banda Aceh City and Sibolga City. The analysis results show that the estimated pure premium value for residential commercial and industrial building types with less than nine floors in Banda Aceh City is around 2.96 and 21.03 times greater than that of Sibolga City. Meanwhile, the estimated pure premium value for commercial and industrial building types with more than nine floors in Banda Aceh City is more minor, around 6.42 times, compared to Sibolga City.

Abstract

Several Land Parcel Geometry issues in Indonesia's Land Registration Process, such as parcel overlapping, gaps between parcels, and incorrect parcel shapes and sizes, are currently being addressed through a block adjustment approach. One crucial aspect of the block adjustment process is determining control points that tie the parcel geometry to the land coordinate system. Detailed Observations and measurements of parcel points in the field and aerial photographs established these control or tie points. Rectifying land parcels requires many control points, requiring substantial time and effort. The automation phase is critical to expedite the control point identification process. This research uses artificial intelligence techniques to identify control points in very high-resolution orthophoto mosaics. The method employed for control point identification involves the Segment Anything Model (SAM) algorithm to segment parcel boundary indications accurately. Enhance the quality of segmentation results conducted by fine-tuning, followed by centerline extraction and refinement of the extracted data. Based on the segmentation, a SAM model capable of accurately segmenting building objects is attained, After the centerline extraction process and modifications to the existing geometric operations within the GIS Tool, at the edges of buildings, fences, and walls derived points. These points can serve as control point indications in the block adjustment process.

Abstract

Institut Teknologi Sumatera (ITERA) is a higher education institution located in the village of Way Huwi, South Lampung Regency. It was established to fulfill the educational needs centered on the island of Suamtera. ITERA campus was formerly a green area used for rubber plantations and forests which underwent transformation due to the demand for academic buildings. This transformations is ecidenced by the construction of the General Lecture Building (GKU) and Engineering Laboratory Building (Labtek) 1-4. This reserarch focuses on GKU 1 and 2, which serve as the central academic hubs for three faculties of ITERA. The aim is to identify issues related to the availability of public green open spaces in each building. Both GKU building have the potential to function as communal zones that can be utilized for discussions, relaxation, and studying due to their distinct characteristics in terms of green space forms and types. The research methodology employs both quantitative and qualitative methods, such as parameters of Responsive Environments, The Likert Scale, and interviews related to the questionnaire, with the primary target audience being ITERA’s students. The research results highlight various shortcomings and advantages in each GKU building. Recommendarions for improvemenr are expected to refine the research outcomes for ITERA.

Abstract

The production volume target from 24.8 million tons in 2020 to 29.5 million tons in 2021 underlies the optimization of transportation availability in distributing coal mining products carried out by PT Bukit Asam Persero in achieving the growing target until 2023. In 2021, the Company will increase investment in developing business diversification, downstream coal. The railway network in Sumatra has a strategic role in serving the distribution of coal transportation. The railway line, which is directly connected to the location of the mining plant to port access and the availability of locomotive facilities and wagons that are very adequate, is an attractive option for mining companies and freight forwarders to establish coal transportation cooperation by rail. To meet the Babaranjang train tonnage target of 52 tons / year in accordance with the target of PT Bukit Asam (Persero), the Loop rail line design at TLS T4 PT Bukit Asam Muara Enim used the most effective classification. From the calculation results, 55 train trips are required per day to transport the production target of 57 tons / year in 2023. It is necessary to pay attention to the adequacy of the rail track from the TLS loop to Tanjung Enim Baru here it is necessary to conduct a study regarding the traffic from TLS to Tanjung Enim Baru because the number of trains set per day is 55 sets.

Abstract

Teaching development in maximum value of a function of two variables is reported in this paper. Based on an experience in teaching numerical method, difficulty in determining step size of steepest ascent gives an idea to covert the function into one variable, so that we can solve numerically by standar method for that function, such as Newton method. Here, we present some examples to support that development.

Abstract

The eruption of Mount Krakatau in 2018, along with high waves, has impacted the coastal conditions of Kalianda Beach. The parameters for planning the revetment include significant wave height, highest high water level (HHWL), refraction and shoaling coefficients, wave set-up, and SLR. Wave data processing was conducted using the FT Type I. The extreme wave 50-year period has a height (Hr) of 2.22 m and a period (Tr) of 14.67 s. The wave transformation coefficients for refraction and shoaling, which are 0.74 and 1.44 respectively, lead to a deformation wave height of 2.19 m at a depth of 5 m. Admiralty tide analysis yielded a tidal range element at MSL of 0.94 m, which serves as the datum for elevation point 0. The HHWL from MSL is 0.73 m, wave set-up is 0.58 m due to breaking waves at 3.43 m, and SLR is 0.16 m, leading to a DWL of 1.46 m. The wave run-up varies according to the type of revetment, boulder type elevations id 4.60 m, tetrapod type is 3.80 m, and dolos type is 4.40 m. Differences elevation are attributed to different wave run-up every type of revetment material, run-up of the type material boulder is 2.83 m, run-up of tetrapod is 2.08 m, and dolos is 2.67 m.

Abstract

Infrastructure development is one of the main points of the program by the Indonesian government, outlined in Nawacita. One of the manifestations of this program in 2019 was the construction of the Gedung Kuliah Umum (GKU) at the Institut Teknologi Sumatera (Itera). As an effort to realize sustainable development, Geodetic surveys named 'as-built surveys' and periodic deformation observations need to be conducted. Both surveys can be done by terrestrial method using total station and satellite method using GPS-RTK. In this article, an analysis of the accuracy, precision and efficiency of the terrestrial method and satellite method for as-built survey and deformation observation at GKU Itera is reported along with a comparison between deformation calculation and direct observation. It was found that the terrestrial method produced better accuracy and precision level (19,5 cm compared to 43,3 cm) than the satellite method with 95% confidence level. In addition, the terrestrial method produces 3 times more data than the satellite method, although on the other hand, the total observation time of the terrestrial method is 100% longer than the satellite method. These results show that periodic monitoring is important for detecting the degree of deformation and realizing sustainable development. In addition, the terrestrial method is more suitable for accurate and precise periodic surveillance of a building than the satellite method. These findings could act as a contribution towards better sustainable deformation monitiring of a building and to underline the importance of having such periodic observations.

Abstract

Smart cities become benchmarks in development cities around the world since the 1990s. In the urban planning context, there are concerns regarding the application of the smart city concept which is considered to only prioritize the progress of cities by technology however no notice to the ecological side of the city. This research discusses the development and arrangement of cities through planning that ensures ecosystem balance, one of which is through open space, which in this case is widely discussed that is green open space. The usual problem that occurs during the development of green open space is not enough land area for available allocation causing an imbalance ecosystem as well as against the sustainability concept. This research method studies literature systematic and bibliometric using Microsoft Excel and VOSviewer from discussion theory and policy about green open space that has been planned in various countries for can applied to cities in Indonesia. The analysis explains the discussion regarding green open space in connection to moving towards a green smart application to cities in Indonesia. Eventually, the findings from this research are discussed related to implementation in the cities in Indonesia which are divided into five aspects, namely political land development, community perception, infrastructure, landscape design, and socio-economic psychology. The final recommendation is that this aspect can be studied further to be applied to cities in Indonesia to realize city smart green future.
