Abstract

The Education Zone is an area with a very high intensity of activity for both drivers and pedestrians, especially among students, hence it requires adequate road facilities to enhance the safety of road users. This study aims to analyze the effectiveness of road facilities found in the Education Zone such as traffic signs, road markings, warning lights, bus stops, and speed control devices on Jl. Prof. Moh. Yamin. The methods used include field observations and analysis of driver compliance with the available road facilities. The results of this study show that the existing road facilities, such as traffic signs and road markings, are less effective in improving safety for drivers and road users.. In addition, the level of compliance among drivers regarding road equipment is very minimal, especially during peak hours. This study recommends improvements and additions to the road equipment according to the needs of the Educational Area to minimize accidents and enhance safety for drivers and road users. This research is expected to serve as a reference for designing a safe traffic movement system in the Educational Area.

Abstract

Indonesia merupakan salah satu negara dengan intensitas gempa bumi yang tinggi sehingga memerlukan perencanaan struktur bangunan yang andal dan tahan gempa. Salah satu sistem struktur yang sering digunakan adalah Sistem Rangka Pemikul Momen Khusus (SRPMK) pada bangunan baja, di mana pertemuan antara balok dan kolom dapat dilengkapi dengan Panel Zone. Keberadaan panel zone diketahui dapat memengaruhi kekakuan dan kinerja seismik suatu struktur. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan panel zone terhadap respons seismik bangunan baja 10 lantai yang menggunakan SRPMK pada kondisi tanah lunak di Kota Medan, sesuai ketentuan SNI 1726:2019 dengan kategori desain seismik D dan faktor keutamaan gempa 4. Metode penelitian dilakukan melalui pemodelan struktur baja 10 lantai dengan dua kondisi, yaitu menggunakan panel zone dan tanpa panel zone, menggunakan perangkat lunak ETABS. Parameter yang dianalisis meliputi roof displacement, story drift ratio, serta verifikasi terhadap konsep Strong Column-Weak Beam (SC-WB) berdasarkan SNI 7860:2020. Hasil analisis menunjukkan bahwa bangunan dengan panel zone cenderung lebih semi-rigid dibandingkan dengan bangunan tanpa panel zone yang lebih rigid. Perbandingan displacement atap menunjukkan peningkatan sebesar 10,63% pada arah X dan 9,25% pada arah Y untuk bangunan dengan panel zone. Demikian pula, nilai story drift ratio lebih besar pada bangunan dengan panel zone, meskipun keduanya masih berada dalam batas aman sesuai peraturan. Hal ini membuktikan bahwa panel zone memungkinkan terjadinya deformasi geser pada sambungan balok–kolom, sehingga struktur dapat menyerap energi gempa lebih baik meski terjadi peningkatan simpangan. Kesimpulannya, penggunaan panel zone dapat meningkatkan daktilitas struktur dengan mengubah perilaku menjadi semi-rigid, namun menyebabkan displacement dan story drift yang lebih besar dibandingkan struktur tanpa panel zone. Rekomendasi dari penelitian ini adalah perlunya perhatian khusus dalam desain sambungan panel zone agar tetap memenuhi kriteria keamanan sekaligus memberikan kapasitas deformasi yang memadai pada struktur baja tahan gempa di Indonesia.

Abstract

This study compares the seismic performance of fixed-base and base-isolated structures for the KAI Boutique Hotel Building in Bandung, a region prone to earthquakes due to active faults such as the Lembang, and Baribis Faults. This study aims to analyze the differences in base shear, displacement, and inter-story drift between the two structural systems using response spectrum analysis, and evaluate the seismic performance level based on ATC-40 guidelines. The research methodology involved modeling an 11-story hotel building in ETABS v.18.1.0 with two scenarios: fixed-base and base- isolated models analyzed by response spectra. The base isolation system uses High Damping Rubber Bearings (HDRB). The main parameters analyzed include base shear, and inter-story deviation. The results show that base isolation significantly reduces base shear. For example, by response spectrum analysis, the base shear is reduced by 54.5% in the X direction and 56.3% in the Y direction compared to the fixed-base system. Base isolation effectively reduced the average inter-storey deviation by 68% in the X direction and 73% in the Y direction. Based on ATC-40, both fixed-base and base-isolated structures achieved the "Immediate Occupancy (IO)" performance level in all analyses, showing minimal structural and non-structural damage, allowing the building to continue functioning after the earthquake

Abstract

This study investigated a slope with tropical residual soil, utilizing SEEP/W and SLOPE/W modules within the Geostudio finite element analysis software. The research focused on examining changes in slope stability under various rainfall patterns and soil parameters. Subsequently, curves illustrating the variation of slope’s factor of safety over rainfall duration were obtained. The result indicate that the advance rainfall pattern has a more significant impact on slope stability compared to the delayed, uniform and peak patterns. Under different rainfall pattern, continuous rain consistently leads to gradual decrease in slope stability. An increase in rainfall directly causes a rise in pore water pressure and a reduction in the factor of safety. Steeper slopes exhibit a more extreme decrease in the factor of safety. The advanced pattern result in a rapid pore water pressure response and a drastic drop in the factor of safety in a short time.

Abstract

The selection of scaffolding type is a crucial aspect in construction project execution, as it significantly affects time effectiveness and cost efficiency. This study aims to analyze the cost and time associated with the use of scaffolding and Perth Construction Hire (PCH) in the construction project of the IME Building at Jenderal Soedirman University (UNSOED), and to compare both methods in order to determine the most optimal alternative. The research employs a descriptive quantitative approach, conducted through observation and the collection of secondary data, including detailed engineering design (DED) drawings, Unit Price Analysis (AHSP), and price lists for scaffolding and PCH. The collected data were analyzed to calculate the time productivity and cost of each scaffolding method. The results indicate that PCH is more effective in terms of time, offering a saving of approximately 4 days or 20% compared to scaffolding. However, in terms of cost, scaffolding is more efficient, as the cost of using PCH is approximately 24% higher. Therefore, it can be concluded that PCH excels in time effectiveness, while scaffolding is more suitable for cost efficiency in the execution of this project.

Abstract

Abstract. Karo Regency is located in North Sumatra Province, including large and crowded regencies. The population in Karo Regency has increased rapidly in recent years. Karo Regency is located in the highlands at an altitude of between 600 and 1,400 meters above sea level which is strategic for the agricultural sector. Infrastructure is very influential in the process of increasing the economy and access to activities in an area such as Karo Regency, especially on the Kutabangun-Kutakendit Road Section at the Pola Tebu Village point STA 0+000 - 2+000. This study aims to determine the condition of road infrastructure and Road Section Development Planning which is a nest of access for the surrounding community to market agricultural products. In this study, the flexible pavement thickness is planned using the 2017 revised Bina Marga Pavement Design Manual method and the 1993 AASHTO Pavement Design Manual Method. Land subsidence on the road body and the small existing road along the Kutabangun-Kutakendit Liang Melas Datas road is one of the factors that threatens the sustainability of the road function, land subsidence on the road body is generally triggered by natural factors such as high rainfall, geological conditions that are prone to landslides and non-scientific factors such as excavation activities at the foot of the slope and deforestation. Based on the results of the analysis and calculations, the results obtained in the 2017 Revised Highways Pavement Design Manual for the surface layer are 10 cm, the upper foundation layer is 40 cm, and the embankment is 17.5 cm, while in the 1993 AASHTO Pavement Design Manual Method, the surface layer is 11 cm thick, the upper foundation layer is 23 cm, the lower foundation layer is 26 cm and the embankment is 10 cm.

Abstract

Penelitian ini bertujuan untuk menganalisis perbandingan biaya dan waktu pelaksanaan pekerjaan sloof dan boundary wall antara penggunaan bekisting batako dan multiplek pada proyek pembangunan The Grey House Buwit Tabanan. pada pelaksanaan pekerjaan di proyek Apartment The Grey House terjadi keterlambatan yang disebabkan oleh kurangnya tenaga kerja. Dimana keterlambatan ini berdampak pada pengerjaan bekisting, terutama pada pengerjaan bekisting batako, yang memerlukan tenaga kerja lebih banyak dan waktu pemasangan yang lebih lama. Akibatnya, pekerjaan sloof mengalami keterlambatan. Pada penelitian ini penulis menggunakan metode AHSP 2022. Bekisting batako dikenal dengan ketahanan dan kemudahan pemasangannya, sedangkan bekisting multiplek lebih efisien dari segi biaya dan waktu. Hasil penelitian menunjukkan bahwa biaya total penggunaan bekisting batako mencapai Rp109.751.543 dengan waktu pelaksanaan 15 hari, sedangkan bekisting multiplek lebih ekonomis dengan total biaya sebesar Rp94.771.377 dan waktu pelaksanaan 30 hari, menghasilkan penghematan biaya sebesar 16%. Meskipun bekisting batako memiliki waktu pelaksanaan yang lebih singkat, bekisting multiplek tetap menjadi pilihan yang lebih efisien untuk proyek dengan anggaran terbatas.

Abstract

Struktur gedung bertingkat pada umumnya didesain dengan asumsi massa seragam di setiap lantai. Namun, kondisi aktual menunjukkan bahwa massa struktur sering kali tidak seragam akibat perbedaan fungsi ruang dan distribusi beban hidup yang bervariasi. Ketidaksesuaian asumsi tersebut dapat memengaruhi perilaku dinamik struktur terhadap beban gempa. Penelitian ini bertujuan untuk menganalisis pengaruh massa tidak seragam per lantai terhadap respon dinamik struktur, yang mencakup perpindahan, drift ratio, gaya geser dasar, periode getar, dan kekakuan struktur berdasarkan ketentuan SNI 1726:2019. Metode penelitian dilakukan dengan analisis numerik menggunakan model gedung 10 lantai sistem rangka pemikul momen khusus (SRPMK). Dua model dibandingkan, yaitu struktur dengan massa seragam per lantai (Model 1) dan struktur dengan massa tidak seragam per lantai (Model 2). Massa tiap lantai dihitung sesuai SNI 1727:2020 dengan mempertimbangkan reduksi beban hidup berdasarkan fungsi ruang. Analisis dilakukan menggunakan metode Response Spectrum Analysis dengan parameter wilayah gempa Kota Padang, kelas situs tanah lunak (SE). Hasil penelitian menunjukkan bahwa struktur dengan massa tidak seragam mengalami peningkatan signifikan pada perpindahan, drift ratio, gaya geser dasar, dan periode getar dibandingkan dengan struktur bermassa seragam. Peningkatan terbesar terjadi pada gaya geser dasar sebesar 10,36% dan drift ratio sebesar 10,19%. Selisih massa total antar model mencapai 17,289%. Walaupun demikian, kedua model masih memenuhi kriteria kekakuan lateral minimum (70%) sehingga tidak terjadi ketidakberaturan tingkat lunak. Kesimpulannya, massa tidak seragam menyebabkan struktur lebih fleksibel dan respons seismik lebih besar. Disarankan agar perencanaan gedung mempertimbangkan variasi fungsi ruang dan beban hidup aktual tiap lantai untuk meningkatkan akurasi analisis seismik. Implikasinya, model massa tidak seragam perlu dijadikan acuan dalam desain struktur tahan gempa guna meminimalkan risiko kerusakan pada kondisi dinamis sebenarnya.
