Abstract

As development progresses in the city of Depok, many of vacant land are being marketed in commercial locations. Land which is in a strategic location makes investors interested in buying the land to be developed into a more profitable commercial building. One of the lands being offered is on Jalan Siliwangi, Depok City, with a land area of ​​4410 m2. This research aims to analyze the financial feasibility of the project if a commercial building is built on the vacant land. The analysis was carried out using technical economic analysis integrated with the Highest and Best Use (HBU) analysis method. By knowing the financial feasibility of the project development plan, investors get earlier information regarding whether or not it is feasible to purchase land and project construction at the research object location. Based on The results of the economic analysis of indicator techniques will determine the financial feasibility of building construction projects such as Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), so the use of Hotels provides the most benefits compared to Offices and Shophouse Complexes. With this level IRR=10.063% > Interest rate 9.311%, which means the project is feasible and can be implemented, then the NPV is >0 (Rp. 7,628,369,872) and the Profitability Index level is 1,060>1. Pay back period 9.2 years (9 years and 2 months).

Abstract

This research was conducted on the construction project of Cimanggis - Cibitung toll road section 2 Sta. 27+070 to Sta. 50+353. The background of this research is the need to know a more efficient implementation method in terms of time and cost, given the importance of effectiveness and efficiency in construction projects. The purpose of this research is to determine the time of girder erection work using the skid launching method and the girder launcher method, Knowing the cost of implementing girder erection work with both methods, Comparing the efficiency of time and cost between the skid launching method and the girder launcher method, The data that has been obtained is analysed. From the results of the analysis of the two tools obtained the results of the erection process, namely the Launcher girder method is more efficient in the time of erection of steel box girder, requiring 6356 minutes compared to 7500 minutes in the Skid Launching method, the data obtained in terms of time while in terms of cost the Launcher girder method is more economical with a cost of Rp 13,867,349 per span compared to Rp 35,767,019 in the Skid Launching method. resulting in cost savings of IDR 21,899,669 or around 39%.From the data obtained, we can determine the most efficient method in terms of time and cost between the two methods. The methodology used in this study includes primary and secondary data collection, analysis of material requirements, productivity and duration of work, and cost analysis. The results showed that the girder launcher method is more efficient in terms of time and cheaper in terms of cost compared to the skid launching method. The findings are expected to serve as a reference in the implementation of similar projects in the future.

Abstract

Coastal protection infrastructure in Jakarta Bay is essential to mitigate flooding due to sea level rise and land subsidence. The use of spun piles with inner boring methods supported by Hydraulic Static Pile Driver (HSPD) technology is intended to ensure efficient and low-impact pile driving operations. However, in practice, productivity discrepancies between theoretical planning and field realization remain a significant issue. This study aims to analyze and compare theoretical productivity (based on contractual planning) with actual field productivity in the installation of spun piles for a coastal safety project in Jakarta Bay Phase 6 Package 4. A descriptive quantitative approach was used, combining direct field observations, time-lapse video analysis, and secondary data from contract documents. Productivity was measured in meters per hour (m/h) and piles per day (piles/day). Deviations between theoretical and actual productivity were identified, and causal factors were analyzed. Theoretical productivity was 3.59 m/h with 3.5 piles/day, while actual field productivity reached only 3.2 m/h with 3.33 piles/day. This discrepancy resulted in an estimated delay of 5 workdays (4.8% deviation). The primary contributing factors were inconsistent hydraulic pressure, environmental constraints, equipment limitations, and varying operator skill levels. The study confirms that real-time monitoring and productivity assessment tools are crucial for timely project delivery. It also highlights the need for adaptive planning and systematic operator training. The findings provide practical guidance for enhancing productivity in future coastal foundation projects using HSPD technology.

Abstract

Urban congestion in rapidly growing cities like Jakarta necessitates efficient, data-driven transportation planning. As part of Indonesia’s efforts to modernize its urban mobility systems, the Jakarta Mass Rapid Transit (MRT) has emerged as a strategic initiative to reduce traffic dependency on private vehicles. While Phase 1 of MRT Jakarta has been operational since 2019, Phase 2 development requires a reliable forecasting framework to anticipate future passenger demand and support infrastructure planning. However, previous studies often rely on macroeconomic projections rather than empirical operational data, leaving a gap in predictive accuracy. This study aims to analyze the influence of MRT Jakarta phase 1 operational data on the prediction of passenger numbers in phase 2 as the basis for evidence-based transportation development planning using a hybrid approach: ARIMA forecasting and multiple linear regression modeling. Primary data were gathered from 125 MRT users via Likert-scale surveys, while secondary data were derived from MRT Jakarta’s operational reports from 2019–2023. Here we show that service quality and multimodal integration significantly increase ridership, while fare levels and poor accessibility negatively affect passenger volume. The ARIMA model, however, shows limited accuracy (R² = 0.164; MAPE = 62.225%), indicating high variability due to pandemic-induced fluctuations. In contrast, regression analysis explains 44.1% of ridership variation, offering a more actionable basis for forecasting. These findings suggest that MRT Phase 2’s success will depend not only on physical expansion but also on improved intermodal integration, user-centered service quality, and competitive fare strategies. The study contributes to transport planning by integrating quantitative modeling with user behavior insights for data-driven infrastructure scheduling.

Abstract

Kawasan wisata Pantai Kuta merupakan salah satu destinasi unggulan di Bali dengan melihat setiap tahun banyaknya wisatawan baik dari dalam negeri maupun mancanegara yang berkunjung ke Pantai Kuta. Namun hal tersebut juga menjadi salah satu tantangan dalam sektor Transportasi yaitu tingginya aktifitas kendaraan bermotor sehingga menimbulkan permasalahan kemacetan dan menurunnya kualitas lingkungan. Selain itu banyak masyarakat dan wisatawan yang beraktivitas salah satunya dengan bersepeda, dikarenakan banyaknya pengguna sepeda menggunakan ruas jalan utama di kawasan Pantai Kuta sehingga akan menimbulkan permasalahan lalu lintas khususnya di bidang keselamatan. Dari banyakanya ruas jalan Kawasan Wisata Pantai Kuta, akan dipilih beberapa ruas jalan yang akan direncanakan sebagai lajur khusus sepeda. Rute sepeda yang terpilih dihitung analisa kinerja setelah sebagian badan jalan digunakan sebagai lajur khusus sepeda serta usulan penempatan rambu dan marka. Pengolahan data analisa yang dilakukan yakni mengenai unjuk kerja kondisi eksisting sebelum adanya lajur sepeda dan kondisi rekomendasi setelah adanya lajur sepeda meliputi kapasitas, V/C ratio,serta tingkat pelayanan jalan tersebut. Dari perhitungan analisa didapat 3 Rute terpilih dengan analisa pertimbangan pengaruh sampai dengan 5 tahun kedepan. Lajur sepeda yang direncanakan ialah dengan lebar 1,6 meter ditandai dengan marka hijau dan dibatasi dengan marka menerus. Penyediaan fasilitas parkir ditempatkan di setiap lokasi tarikan perjalanan.
