Abstract

The Solo Wonogiri corridor is one of the seven agglomeration areas served by the Trans Jateng Bus and is widely utilized by the public. This service system adopts a buy-the-service scheme based on six Minimum Service Standard (SPM) indicators: comfort, security, safety, affordability, equality, and orderliness. To support service quality improvement, an evaluation of user perceptions is necessary as a foundation for providing policy recommendations to the government. This study assesses the service quality of the Trans Jateng Bus on the Solo Wonogiri route using the Importance Performance Analysis (IPA) method across 14 service attributes. The IPA method categorizes attributes into four quadrants based on their level of importance and passenger satisfaction to identify which aspects should be maintained or improved. The analysis results indicate an average conformity level of 94%, reflecting a very satisfactory service quality, although several attributes still require improvement. Among the 14 attributes, two are positioned in quadrant I (top priority for improvement), five in quadrant II (should be maintained), two in quadrant III (low priority), and five in quadrant IV (excessive). These findings can serve as a reference for formulating strategies to enhance public transportation services in the Solo Wonogiri corridor.

Abstract

Based on data from the Central Statistics Agency (BPS), the population of Cilacap has increased by 300,282 people over the past five years. With rapid population growth, the need for housing is becoming increasingly difficult to meet. The Ministry of Public Works and Public Housing (PUPR) is committed to building public housing as a solution to this problem. However, to ensure that these buildings are livable and sustainable, it is important to conduct a comprehensive cost analysis. In construction projects, life cycle cost analysis is one of the efforts to prepare for the need to understand that costs are not limited to the construction phase. Construction projects often only consider initial costs, which can lead to errors in long-term financial planning. Life Cycle Cost Analysis helps in long-term planning, enabling decision-makers to consider all aspects of costs that will arise throughout the building's lifespan. This not only improves budget efficiency but also ensures that residents receive adequate housing facilities. Therefore, it is necessary to conduct research on the economic value analysis of a building, specifically in the form of life cycle cost planning, for a low-cost apartment building with a 25-year lifespan. This analysis should encompass initial costs, operational costs, and maintenance and replacement costs. This research is quantitative. The method used is life cycle cost. Data collection methods include field observations and interviews. The research results indicate that the life cycle cost (LCC) planned for a 25-year lifespan amounts to Rp 20,486,745,640, comprising initial costs of Rp 13,446,741,389 (54.07%), operational costs of Rp 5,832,349,683 (23.45%), maintenance costs of Rp 1,940,837,459 (7.80%), and replacement costs of Rp 3,649,042,776 (14.67%).

Abstract

Kabupaten Pacitan adalah salah satu kabupaten di Indonesia yang memiliki aktivitas seismik tinggi akibat berada di antara tiga lempeng tektonik. Aktivitas seismik yang terjadi dapat menyebabkan terjadinya kerusakan bangunan dan korban jiwa. Namun, sebagian besar rumah tinggal di Indonesia tergolong sebagai bangunan non-rekayasa, yaitu bangunan yang dibangun tanpa perhitungan struktur sesuai standar yang berlaku. Salah satu faktor penting dalam ketahanan struktur terhadap gempa adalah kekakuan pada sambungan balok-kolom serta keberadaan elemen non-struktural seperti dinding pengisi. Joint balok kolom merupakan komponen struktur utama yang berfungsi mengikat beban-beban struktur lainnya yang merupakan beban siklik terhadap joint balok kolom. Adanya bukaan pada dinding juga mempengaruhi perlakuan dari dinding tersebut. Penelitian ini bertujuan untuk mengevaluasi pengaruh kekakuan joint balok kolom dan dinding dengan bukaan terhadap kinerja seismik struktur rumah tinggal non-rekayasa. Evaluasi dilakukan menggunakan metode Incremental Dynamic Analysis dengan software seismostruct yang berfungsi untuk menentukan respon  struktur bangunan terhadap beban gempa. Berdasarkan hasil penelitian, adanya bukaan pada dinding pengisi memberikan reduksi dalam menahan gaya lateral. Kemudian kekakuan hubungan balok kolom tidak menunjukkan dampak yang berarti terhadap peningkatan kinerja seismik bangunan. Hal ini dapat dilihat dari periode struktur dan nilai gaya geser dasar pada setiap kerusakan.

Abstract

Analisis struktur yang tepat dapat mencegah kegagalan struktural dan memperpanjang usia pakai suatu bangunan gedung. Oleh karena itu, analisis struktur dalam konteks proyek pembangunan gedung olahraga Unimuda Sorong menjadi sangat penting untuk dilakukan. Penelitian ini bertujuan untuk mengevaluasi tingkat keamanan struktur, menghitung beban ultimate pada setiap elemen, menganalisis deformasi struktur, dan mengevaluasi kekuatan sambungan baut. Struktur bangunan menggunakan material baja dengan dimensi 50 m x 24 m, tinggi kolom 6 m, dan bentang kuda-kuda 24 m. Analisis struktur menggunakan metode LRFD (Load and Resistance Factor Design) dengan bantuan aplikasi SAP2000 v.22. Analisis dan perhitungan mengacu pada SNI 1726:2019, SNI 1727:2020, SNI 1729:2020, dan PPURG 1987. Hasil analisis menunjukkan 20 elemen struktur (rafter dan balok) mengalami kondisi overstressed dengan PM-Ratio > 1,00. Beban ultimate terbesar dipikul elemen kolom dengan Pu = -64,617 kN, Vu = 32,126 kN, dan Mu = 99,3886 kN.m. Deformasi maksimum akibat kombinasi beban ultimate sebesar 0,259 m. Perhitungan sambungan baut menunjukkan kekuatan memadai dengan nilai 0,635 < 1 (sambungan rafter-kolom) dan 0,685 < 1 (sambungan antar rafter), serta kuat tumpu pelat 1.234,4 kN > 662,4 kN.

Abstract

The increase in infrastructure development in Indonesia has directly impacted the high demand for concrete. The increased use of concrete has the potential to cause negative effects on the environment. To support sustainable infrastructure development, innovative concrete has been developed by utilizing stone dust as a partial substitute for fine aggregate. This study aims to determine the optimum content of stone dust as a partial substitute for fine aggregate on the tensile strength and modulus of rupture of concrete. The research method used is the experimental method. The concrete mix design uses variations of stone ash at 0%; 5%; 10%; 15%; and 20% of the weight of the fine aggregate. The test specimens for the split tensile strength test are cylindrical with a diameter of 15 cm and a height of 30 cm, while the test specimens for the modulus of rupture test are beam-shaped with a width of 10 cm, height of 10 cm, and length of 40 cm, and all specimens are tested at 28 days old. Hardened concrete testing for split tensile strength uses a Compression Testing Machine, and modulus of rupture testing uses a Universal Testing Machine. The results of the split tensile strength test were 2,45 MPa; 2,57 MPa; 2,64 MPa; 2,78 MPa; and 2,71 MPa, with R² = 0,923. The results of the modulus of rupture test were 4,00 MPa; 4,32 MPa; 4,62 MPa; 5,10 MPa; and 4,85 MPa, with R² = 0,909. The split tensile strength and modulus of rupture reached their optimum values at stone ash contents of 17,83% and 19,31%, respectively.

Abstract

Population growth, economic development, and improved public welfare in Indonesia have led to a significant increase in domestic waste generation. In Lamongan Regency, this condition has directly contributed to the growing amount of waste disposed of at the Tambakrigadung Landfill. The accumulation of large volumes of waste produces leachate, a dark-colored liquid formed through rainwater infiltration and the decomposition of organic matter. This leachate contains various hazardous pollutants, including heavy metals such as mercury (Hg) and cadmium (Cd), which can contaminate soil and groundwater. This study aims to analyze the potential distribution of leachate contaminants using GMS-based MODFLOW and MT3DMS modeling, as the first application at the Tambakrigadung Landfill. Model parameters were derived from primary and secondary data, assuming a single saturated aquifer and steady-state flow conditions. Simulations were carried out over 25 years to map groundwater flow directions and contaminant distribution patterns. The MODFLOW simulation results indicate a dominant groundwater flow direction from south to north, while MT3DMS results show that after 25 years, Hg contaminants spread approximately 112 meters with a final concentration below 0.005 mg/L, and Cd spread about 107 meters with a concentration below 0.021 mg/L. The very low RMSE values (Hg = 0.0006; Cd = 0.0002) indicate a high level of model accuracy in representing actual field conditions.
