Abstract

Pembangunan Proyek Jalan Lingkar Selatan di Kabupaten Sampang dibangun untuk memenuhi kebutuhuhan jalan. Tujuan dibangunnya proyek ini, agar semua kendaraan besar dapat melewati Kabupaten Sampang dan mampu menurunkan kepadatan kendaraan di jalan masuk ke pusat kota. Namun, perencanaan proyek ini masih berpedoman pada Tata Cara Perencanaan Geometrik Jalan Antar Kota No. 038/TBM/1997. Maka dari itu dirancang ulang berdasarkan Pedoman Desain Geometrik Jalan (PDGJ) No. 13/P/BM/2021. Selain itu, akan dilakukan identifikasi terhadap kondisi eksisting dan analisis hingga mendapatkan elemen perencanaan geometrik yang memenuhi standar menurut PDGJ tersebut. Data yang digunakan berupa data sekunder meliputi peta topografi, titik koordinat, dan volume lalu lintas harian yang diperoleh dari dokumen perencanaan pembangunan proyek. Selanjutnya dianalisis menggunakakan PDGJ 2021 dengan software desain AutoCAD Civil 3d 2018. Berdasarkan hasil perhitungan didapat bahwa beberapa komponen geometrik jalan yang tidak memenuhi kriteria, baik pada perencanaan alinemen horizontal maupun vertikal. Hasil akhir yang diperoleh dari perencanaan ulang geometrik jalan ini berupa alinemen horizontal sebanyak 15 tikungan yang terdiri dari 10 tikungan S-C-S dan 5 tikungan F-C. Bukan hanya itu, melainkan juga ada 10 lengkung vertikal yang terdiri dari 5 lengkung vertikal cekung dan 5 lengkung vertikal cembung.

Abstract

The need for efficient and environmentally friendly building construction demands innovation in material selection and structural design, including the use of lightweight steel roofs. This study aims to design a lightweight steel roof structure adopting the Kaleles Sapi Kerapan design in Sumenep that safely withstands loads, efficiently uses materials, and supports solar panel integration as an alternative energy source. The methodology includes literature study, geometry and material data collection, and numerical modeling using SAP2000 v22.0.0 Ultimate software with linear static analysis according to SNI 7971:2013. Loads analyzed include dead load, live load, and wind load with various combinations. Simulation results indicate the roof frame design has strength ratios below 1 and is therefore safe. The total material requirements include C75 trusses, battens, braces, screws, spandek sheets, and ridge elements in measured quantities. This lightweight steel roof design is structurally feasible, economical, and supports sustainable building concepts.

Abstract

Passenger satisfaction is an important indicator of service performance in public transportation, particularly for local railway services that support regional mobility. This study aims to evaluate passenger satisfaction with the local train operating on the Madiun–Solo route using the Customer Satisfaction Index (CSI) method. The research was conducted in the operational area of DAOP 7 Madiun and involved 250 passengers as respondents. Data were collected through field surveys using structured questionnaires that assessed six service dimensions: tangibles, reliability, responsiveness, assurance, empathy, and accessibility. The CSI analysis results indicate an overall satisfaction index of 69.50%, which falls within the “satisfied” category, suggesting that the service generally meets passenger expectations. Nevertheless, several service attributes, including service frequency, seating arrangement, ticketing convenience, and feeder transport availability, show relatively lower satisfaction levels and require improvement. These findings emphasize the importance of continuous service enhancement to improve passenger experience and increase the attractiveness of local rail services. The results are expected to serve as a reference for transportation operators and policymakers in developing sustainable railway services along the Madiun–Solo corridor.
