Perhitungan Kebutuhan Air Bersih dan Perencanaan Kebutuhan Infrastruktur Perpipaan PDAM di Kel Sako, Sako Baru, Sialang dan Sukamaju Kec. Sako Kota Palembang

The service of clean water in urban areas is very important to be given special attention. PDAM Tirta Musi The Sako Kenten Service Unit serves 4 sub-districts in Sako sub-district, including Sako, Sako Baru, Sialang, and Sukamaju. As the area grows, the population also increases. It is estimated that in 2029 the total population in Sako sub-district will reach 106,273 people. Meanwhile, for now the population which only reaches 93,326 people, it is felt that there is a shortage of clean water supply from PDAM. Based on the results of surveys and interviews, information was obtained that the availability of clean water from PDAM in the Sako area is only 6,000 liters per month on average. This is not enough for the population. It becomes a big task for PDAM Tirta Musi to prepare it by building an adequate pipeline network. Another problem is the existing piping system does not support the flow with such a large discharge, so it requires a network using the latest material, namely using HDPE pipes. The use of this material was chosen because HDPE does not require much connection and the pipe is stronger than PVC pipe. After carrying out the survey and calculation of the RAB, it was found that the need for a new network system reached Rp. 53,756,600,000, - in order to meet service standards for 80% of the population in Sako District.

Pioneer trains in Indonesia have been fully funded by the government. The construction needs a lot of funding that would burden the state budget. One of the alternatives is the public-private partnership scheme. This study aims to analyze the most effective unbundling scenario for financing and maintaining the Indralaya-Tanjung Senai train. The life cycle costs and conducting sensitivity analysis according to applicable regulations. The scenarios are based on ticket price increases and government support for the operation and maintenance (O&M) for this pioneer train route, calculated net present value (NPV) and internal rate of return (IRR) value. Scenario 1 assumes that tickets do not receive subsidies; private companies are responsible for O&M costs. Scenario 2 assumes that ticket prices are set by private companies; the government is responsible for procurement and maintenance costs. Scenario 3 assumes that the government provides subsidies of IDR 10,000 per passenger as well as railway infrastructure; private companies bear the cost of procuring railbuses and operational expenses. Based on calculations with Scenario 1 NPV is IDR 0.73 billion; with Scenario 2 is IDR 4.64 billion and with Scenario 3 is IDR (–)1.34 billion. The analysis shows that increasing passenger fares according to price raises and inflation rates, and subsidies from governments for maintenance costs will make this railroad project financially feasible

Penggunaan Foam Agent Pada Beton Untuk Pembuatan Beton Ringan

Stabilitas dan level penurunan pada jalan yang menggunakan timbunan di atas tanah lunak akan bergantung pada berat timbunan. Tanah yang lunak akan sulit untuk menahan beban timbunan sehingga sering terjadi penurunan level tanah. Hal ini dapat merusak struktur bangunan di atas tanah timbunan tersebut. Salah satu solusi yang dapat dilakukan adalah dengan menimbun menggunakan material ringan sehingga dapat mengurangi berat timbunan dan mengurangi  tengangan pada tanah timbunan. Hal ini akan berdampak pada penurunan tanah dan membuat tanah menjadi lebih stabil. Salah satu jenis material ringan yang sesuai persyaratan dan dapat menjadi solusi adalah dengan menggunakan beton yang telah ditambahkan foam agent.  Foam Agent sendiri merupakan zat kimia yang mengandung sufaktan yang berguna untuk membentuk gelembung udara pada permukaan sehingga dapat menurunkan tegangan permukaan suatu zat.
