Abstract

This study aimed to identify ways to enhance service quality, with the expectation of providing effective handling solutions and input for related parties in the context of sustainable urban development, particularly in Transjakarta. One hundred surveys were sent to passengers utilizing Transjakarta services on the BKN-Depok route, after which the data were processed and analyzed using IPA and QFD methodologies. Based on the results of the analysis of the Importance Performance Analysis (IPA) and Quality Function Deployment (QFD) methods, here is a positive relationship between fulfillment of customer requirements identified through QFD and improved bus performance, strengthening service maintenance and repair SOPs and periodic monitoring and evaluation of the system are the main concerns and must be improved. This study provides valuable insights for educational management, particularly in developing curricula that integrate aspects of public services and urban transportation. The findings underscore the importance of enhancing students’ understanding of quality management methodologies, such as IPA and QFD, to improve the management of sustainable public transportation systems.

Abstract

Persaingan bisnis terus meningkat, terutama industri atap fibersemen. Hal ini ditandai dengan semakin banyaknya industri sejenis yang bermunculan. Untuk mempertahankan kelangsungan bisnisnya berbagai upaya perbaikan harus dilakukan oleh pelaku bisnis atap fibersemen, salah satunya adalah penerapan Lean Manufacturing. Penelitian ini dilakukan pada salah satu line mesin di industri atap fibersemen dengan stoppages/downtime mesinnya 4.45%, hal ini menjadi masalah besar terhadap hasil produksi. Perusahaan hanya memberikan batasan stoppages/downtime setiap mesin sebesar 2%. Tujuan penelitian ini adalah mengetahui penyebab utama dari downtime mesin, kemudian menentukan tindakan perbaikan sebagai implementasi Tingkat Kesiapterapan Teknologi Level 8. Metode yang digunakan adalah DMAIC. DMAIC meliputi tahapan define, measure, analyze, improve dan control. Setelah diidentifikasi ternyata permasalahan menunjukkan bahwa proses pemotongan menggunakan water jet merupakan penyebab utama downtime. Tindakan perbaikan berupa penggantian sistem pemotongan menjadi circular saw. Hasil perbaikan ini dapat menurunkan downtime mesin sebesar 70% dari masalah utama yang sudah ditentukan.

Abstract

Road infrastructure development is crucial for mobility and the economy; design must satisfy geometric, structural, and drainage aspects. The research method used was a direct survey in the field to obtain primary data in the form of horizontal curve data, vertical slope, and other existing road geometric conditions. In addition, secondary data was obtained through literature studies and relevant supporting technical documents. This study analyzes the geometry of the Cibogo KM 9 road segment, ±2 km, in Padaasih Village, Subang. Referring to PDGJ 2021 and PKJI 2023; using 2025 LHR data, traffic growth of 8% (left direction) / 7.5% (right direction), a subgrade CBR of 5.5%, a design speed (Vr) of 70 km/h, and rainfall of 1,400–1,800 mm/year. The alignment produces 5 Spiral–Spiral curves with R = 250 m, the overlapping control is OK, and the cross-section type is 2/2 TT (two-lane, two-way, undivided). Drainage channel capacity from STA 0+000 – 2+024.63 using a 100 × 100 × 120 cm channel type (precast concrete), at 100-meter intervals, results in Q < Qsal. The design meets geometric criteria and base/drainage channel capacity requirements. These findings are expected to form the basis for recommendations for road improvements in the future.

Abstract

fungsi strategis sebagai penghubung antara Kabupaten dan Kota Cirebon. Jalan ini berperkerasan lentur dengan lebar 7 meter. Analisis lalu lintas tahun 2025 menunjukkan pertumbuhan 4,5% pada arah kiri dan 7,5% pada arah kanan, menghasilkan volume desain sebesar 6.758 SMP/hari. Data tersebut menjadi dasar perhitungan kapasitas dan kebutuhan pelebaran jalan. Analisis geometrik dilakukan pada tiga tikungan utama menggunakan metode alinyemen horizontal dan vertikal. Perhitungan meliputi jari-jari lengkung minimum, super elevasi, panjang lengkung spiral, serta pelebaran perkerasan. Hasil menunjukkan bahwa seluruh tikungan memerlukan lengkung peralihan dengan pelebaran perkerasan antara 0,55–0,61 meter. Selain itu, jarak pandang henti dan menyiap dihitung untuk menjamin keselamatan pengguna jalan. Struktur perkerasan dirancang menggunakan sistem lentur dengan kombinasi material HRS-WC sebagai lapis permukaan dan CTB sebagai lapis pondasi bawah. Tebal total perkerasan mencapai 200 mm. Pertimbangan desain mencakup nilai CBR tanah dasar sebesar 6,5%, curah hujan tahunan 1.400–1.800 mm, serta kecepatan rencana 60 km/jam. Studi ini memberikan gambaran komprehensif mengenai tahapan desain geometrik, analisis lalu lintas, dan kebutuhan teknis perkerasan. Rekomendasi teknis meliputi pelebaran perkerasan di tiga tikungan, penerapan lengkung peralihan, serta struktur perkerasan lentur sesuai kondisi tanah dan iklim. Hasil akhir diharapkan menjadi acuan dalam pengambilan keputusan teknis dan perencanaan anggaran pembangunan jalan, sekaligus mendukung efisiensi transportasi dan keselamatan pengguna di wilayah Cirebon.

Abstract

Road infrastructure design is an important aspect of regional development, especially in areas with high mobility such as Waled District, Cirebon Regency. This study aims to redesign the ±2.8 km section of Jl. Raya Waled Desa – Jl. Raya Jatimulya, Mekarjaya to meet the geometric standards for secondary collector roads as stipulated by the Directorate General of Highways. The research method was conducted through field surveys to obtain primary data on existing road conditions, topography, drainage, and traffic flow, which were then analyzed using civil engineering software such as Autodesk Civil 3D. The analysis results showed that the average width of the existing pavement was 5.5 meters with moderate to severe damage, so it needed to be widened to 6 meters to meet the standards. The maximum slope value of 3.2% is still within tolerance limits, but several points require elevation improvements to overcome flooding. Curve analysis shows that several segments have a radius of less than 90 meters, so superelevation improvements and curve widening are needed to ensure vehicle safety. Traffic load calculations (ESA5) show a total design load of 6,491,947 ESA (left direction) and 8,712,590 ESA (right direction), which are used as the basis for pavement thickness planning. In addition, a hydrological analysis using the Manning method resulted in a channel capacity of 1,643 m³/second with a flow velocity of 0.6 m/second, indicating that the drainage system needs improvement to accommodate rainwater runoff.
