South Kalimantan Province is experiencing population growth and is planned to serve as a supporting area for the National Capital (IKN) of Nusantara. Banjarbaru City, as the provincial capital, is viewed as a potential center for economic growth. The region surrounding Syamsudin Noor Airport is also projected to develop into a hub of strategic activities, which could lead to traffic congestion. Besides Banjarbaru, high passenger demand has also been observed in Banjarmasin City and Martapura. According to the 2030 National Railway Master Plan (RIPNAS), a railway line is planned to connect Banjarmasin, Syamsudin Noor Airport,
Banjarbaru, and Martapura. Currently, there is no geometric design available for this railway line, making it necessary to develop a suitable design that aligns with the topographic and other local conditions. This study employs AutoCAD Civil 3D and other supporting software to create the railway design. The proposed railway line spans 42.940 kilometers, with a planned operational speed of 100 km/h, consisting of both at-grade and elevated sections. The design incorporates 15 horizontal curves, with radii of 1660 meters for Full-Circle curves and 560 meters for Spiral-Circle Spiral curves. The railway is classified as Class I, with a 1435 mm gauge and a double track configuration. The rail type used is 141RE, paired with S-35 concrete sleepers produced by PT. WIKA Beton, and fastened using KA Clip fasteners. The ballast layer has a top layer thickness of 30 cm, while the sub-ballast is 45 cm thick. The estimated construction cost is Rp31,333,291,269,000.00.

Trains are a mass transportation system that has existed for a long time. The condition of the train density needs to be considered because train
transportation benefits people who will travel. The parameters analyzed include the train railway, signaling, total passengers and facilities of each station. The methods used are overlay, buffer, and intersection methods. Based on the results of the analysis, the most passengers are 24,998 passengers at Bekasi station with a station area of 15.838m2 and the smallest passengers are 3,315 every day with an area of 2.139 m2 at Telaga Murni station. Facilities at large stations and at small stations are mostly the same in accordance with Minister Regulation number 3 of 2011 and what distinguishes each station is based on the weight class of the station. Analysis using buffers aims to analyze the level of passenger density at each station and existing facilities by visualizing them using a Web Map.
The adding facilities that need to be added and evaluated include an ATM and adding the parking park in each station.

Planning The Pasuruan–Probolinggo Section Iv-A Toll Road (Clarak Sta 31+300 To Pendil Sta 39+875)

Probolinggo has considerable tourism potential. This has an impact on economic growth in Probolinggo. With the increasing need for vehicles, the capacity of the road will also increase. To overcome these problems, the
government is increasing road capacity by building expressways (Toll Roads). The Pasuruan-Probolinggo expressway (Tol) section IV was built
to cope with the increasing traffic volume every year. The PasuruanProbolinggo Toll Road is also a program from the government to overcome congestion on the main arterial road Pasuruan-Probolinggo. In this discussion, it will be explained about the planning of the PasuruanProbolinggo toll road section IV which connects Leces District with Gending which will be assisted by AutoCad Civil 3D software.To plan
geometrically, the author refers to the guidelines of the Highway Regulation for Geometric Planning of Freeways No.007/BM/2009 and for
road pavement planning using the Manual Guidelines for Road Pavement Design No.04/SE/Db/2017. Drainage planning refers to regulation Pd-T-2- 2006-B, for the calculation of the Cost Budget Plan using the 2023 Probolinggo City Unit Price Standard and Price Analysis Unit Work Unit. From the results of this road design, the number of horizontal curves is 6 curves and 22 vertical curves. The pavement uses flexible pavement with a thickness of AC-WC 40 mm, AC-BC 60 mm, AC-Base 100 mm, CTB 150 mm, LFA Class A 150 mm. Drainage is planned in the form of a trapezium made of concrete with 3 different sizes for side channels and 3 different sizes for culverts, the total cost of the plan design reaches Rp. 262,508,286,380.00 (Two hundred and sixty two billion five hundred eight million two hundred eighty-six thousand three hundred and ten rupiah)

Heterogeneous Vehicle Routing Problem with Simultaneous Pickup and Delivery to Optimize Last Mile Deliveries of Sustainable Retail

Ezra Athalla Oktafianto, Niniet Indah Arvitrida — Sat, 19 Jul 2025 00:00:00 +0000

Transportation, as one of many elements of logistics, accounts for 30-60% of the total logistics cost, making it essential to be arranged as efficient as possible as it contributes to greater competition in the market, greater economies of scale, and reduced prices of goods. One initiative to achieve transportation efficiency is the Vehicle Routing Problem. PT Siklus. The Vehicle Routing Problem is carried out in this research for PT Siklus Refil Indonesia or Siklus, an Indonesian-based sustainable retail startup, which
mission is to reduce plastic wastes. Siklus offers a unique shopping experience, in which once the order is delivered to the customers, they can
store used containers or waste, which will then Siklus collect and cultivate for greater good. However, due to the last mile delivery activities,
maintaining the logistics cost to be minimum has been a never-ending challenge to overcome. Therefore, the Heterogeneous Vehicle Routing
Problem with Simultaneous Pickup and Delivery and Time Windows is developed, striving to optimize the last mile deliveries of Siklus, hence
minimum total cost is achieved. Based on the results, it is found that the proposed model leads to cost saving as much as 31.28% from the existing condition.

Feasibility Study of Sigli - Banda Aceh Toll Road In Term of Financial And Economics

Muhammad Abiyyu Syauqi, Hera Widyastuti — Sat, 19 Jul 2025 00:00:00 +0000

The Province of Nanggroe Aceh Darussalam with its capital city, Banda Aceh, is one of the capital cities with areas that are still lacking in terms of infrastructure when compared to other capital cities in Java. Even though conditions the highways in the city of Banda Aceh itself quite good, but till this day the people of Aceh still need to spend a long time traveling out of town. Therefore, the government also built the Toll Road Sigli– Banda Aceh as one of the solutions in terms of travel time efficiency as well improve road network connectivity. Badan Pusat Statistik (BPS) noted that the Special Region of Aceh has become the poorest area compared to other regions in Sumatra since 2002. In 2002, the number of poor people in Aceh amounted to 1.19 million people or 29.83%. The feasibility and financial study conducted with calculating the savings value of Vehicle Operating Cost (VOC) of existing road and toll road, time value of existing road and toll road as the parameter to calculate the Benefit Cost Ratio (BCR), Net Present Value (NPV), toll rates, Economic Internal Rate of Return (EIRR),
and Financial Internal Rate of Return (FIRR). Furthermore, we will know the feasibility of the toll road Sigli - Banda Aceh in terms of economic and
financial analysis. The results of the Economics NPV is Rp5,191,247,611,134 (NPV<0), it was concluded that the construction of the Sigli – Banda Aceh Toll Road is economically not feasible. The Financial NPV analysis, it was found that the NPV value was Rp2,307,253,704,888(NPV>0). Therefore, Sigli – Banda Aceh Toll Road is financially feasible with Viability Gap Funding value of 3.30%.
