Abstract

Wirosari Bus Terminal, a Type-C terminal located in Grobogan Regency, plays a crucial role in supporting rural mobility. However, underutilization and non-compliance with Indonesia's Minimum Service Standards (SPM) have significantly hampered its performance. This study evaluates the availability and quality of terminal facilities and proposes a technological optimization model based on the Internet of Things (IoT). Using a quantitative research design, 92 respondents including users, operators, and terminal staff were surveyed. The data were analyzed through multiple linear regression to determine the influence of facility availability (X₁) and technology perception (X₂) on terminal performance (Y). Results indicate that perceived facility availability is low (mean = 2.70), while technology acceptance is high (mean = 4.68). The regression model reveals that both variables significantly affect terminal performance (R² = 0.284, p < 0.05). This study concludes that enhancing physical infrastructure combined with IoT-based digital innovations such as real-time scheduling displays, electronic queuing, and sensor-based monitoring can significantly improve terminal functionality, user satisfaction, and operational transparency, especially in rural contexts.

Abstract

Penelitian ini menganalisis faktor-faktor penyebab keterlambatan penyelesaian proyek pembangunan Menara Masjid Agung Sumber di Kabupaten Cirebon. Menggunakan metode House of Risk (HOR), tahap pertama mengidentifikasi 30 agen risiko, dengan 20 risiko prioritas berdasarkan nilai Aggregate Risk Potential (ARP) tertinggi. Risiko utama meliputi kesalahan perencanaan material, estimasi waktu yang tidak akurat, keterlambatan pengiriman, miskomunikasi, dan lemahnya quality control. Tahap kedua menghasilkan 13 strategi mitigasi utama berdasarkan nilai Effectiveness to Difficulty Ratio (ETD), seperti penyusunan regulasi teknis, pelatihan pekerja, sistem reward & punishment, dan peningkatan koordinasi proyek. Strategi ini diharapkan mampu mencegah keterlambatan dan meningkatkan efisiensi pelaksanaan proyek.

Abstract

Penelitian ini bertujuan mengembangkan model prediktif bangkitan perjalanan pada Tempat Istirahat dan Pelayanan (TIP) atau rest area di jalan tol Indonesia. Data primer dikumpulkan dari delapan rest area aktif di koridor tol Trans-Jawa selama enam hari pada tahun 2024, yang mencakup dua periode berbeda, yaitu Lebaran (arus puncak) dan non-Lebaran (arus reguler). Pendekatan regresi multivariat digunakan untuk mengidentifikasi variabel signifikan yang memengaruhi volume kendaraan dan durasi lama singgah pengunjung, dengan membedakan variabel deterministik—seperti luas lahan, jumlah nozel pompa SPBU, jumlah fasilitas standar dan tambahan, konektivitas, serta arah perjalanan—dan karakteristik stokastik berupa ketidakpastian waktu kedatangan kendaraan pengunjung. Model prediktif dibangun terpisah untuk kedua periode guna menangkap variasi musiman perilaku pengguna jalan tol. Selain itu, dilakukan analisis fungsi distribusi probabilitas untuk menentukan distribusi statistik paling sesuai dalam memodelkan karakteristik stokastik lalu lintas pengunjung. Model divalidasi menggunakan uji chi-square, AIC, BIC, RSME, MAE, dan MAPE untuk mendapatkan model terbaik masing-masing periode, serta dibandingkan dengan literatur dan standar teknis sebelumnya. Hasil penelitian menunjukkan bahwa pada periode Lebaran, keputusan singgah di rest area lebih dipengaruhi oleh ketersediaan SPBU bersubsidi dan kapasitas pompanya, sedangkan pada periode non-Lebaran lebih dipengaruhi oleh kelengkapan fasilitas di rest area. Pola kedatangan kendaraan ke rest area pada periode Lebaran menunjukkan fluktuasi yang jauh lebih tinggi dan mengikuti distribusi log‑normal, sedangkan pada periode non‑Lebaran pola kedatangan relatif stabil dengan sebaran yang lebih seragam (uniform). Model yang dihasilkan lebih akurat untuk kondisi di Indonesia dibandingkan dengan standar dan literatur sebelumnya. Model ini diharapkan menjadi dasar bagi standarisasi bangkitan perjalanan dan menjadi dasar pengambilan keputusan berbasis data untuk desain, pengelolaan, dan mitigasi rest area tol nasional.

Abstract

This study aims to analyze the effect of using pumice as a partial substitute for fine aggregate on the compressive strength, splitting tensile strength, flexural strength, unit weight, and workability of lightweight concrete. The research method employed laboratory experiments with a design strength of fc’ 20 MPa based on SNI 7656:2012. The pumice substitution levels were set at 0%, 5%, 10%, and 15% of the fine aggregate weight, with the addition of a superplasticizer at 0.5% of the cement weight. Tests were conducted at 7 and 28 days of concrete age using a Universal Testing Machine to obtain the concrete’s mechanical parameters. The results showed that increasing the pumice content caused a decrease in the concrete’s unit weight and slump value due to the high porosity and water absorption of the pumice aggregate. Substitution levels of 5% and 10% still produced relatively stable compressive strength, tensile strength, and flexural strength, meeting the design quality standards for normal concrete. A 15% substitution showed a more significant decrease in mechanical strength due to increased internal voids and weak interlocking between materials. This study confirms that pumice has the potential to be used as an alternative material in the development of lightweight concrete with controlled weight efficiency and mechanical performance.

Abstract

This study aims to analyze the effect of repeated seismic loading cycles on the mechanical behavior of geosynthetic-reinforced soil using a numerical simulation approach based on the finite element method. Modeling was performed using PLAXIS 2D v22, representing a 10-meter-high soil embankment on soft subgrade based on Standard Penetration Test data from the Solo–Yogyakarta Toll Road project at STA 0+616. Reinforcement systems using woven and non-woven geotextiles were modeled under cyclic loading conditions in the form of a sinusoidal wave with a maximum ground acceleration of 0.4562 g, a frequency of 0.8 Hz, and 50 loading cycles. The analysis results show that the use of geosynthetics is capable of improving system stability and significantly reducing deformation compared to unreinforced soil. Woven geotextiles produced the most optimal response with a maximum deformation of 2.699 × 10⁻³ m and a safety factor of 1.488 due to their higher tensile stiffness capacity. Non-woven geotextiles still improved soil performance, but their effectiveness was lower under repeated dynamic loading. The mechanical response of the soil is influenced by soil–geosynthetic interaction, dynamic stress distribution, reinforcement layer configuration, and cyclic loading characteristics. The research findings underscore the importance of integrating dynamic analysis into geotechnical design in earthquake-prone regions to enhance the long-term stability and resilience of infrastructure.
