Drainage is a basic facility that must be provided to meet community needs, so it’s very important in urban spatial planning. The benefit of building drainage is to prevent stagnant water so that it does not interfere with community activities. The condition of the drainage channels on Jalan Marina isn’t maintained because the dimensions of the channels are small and sedimentation occurs, causing silting of the channels. This causes floods that always occur every year. Re-dimension of the drainage channel was carried out because the initial dimensions could not accommodate the planned flood discharge. Some of data the basic for determining the re-dimensional drainage channels are rainfall data, sea tide data, and initial drainage channel dimension data. From the calculation results, the value of planned flood discharge is 172.634 mᶟ/s. So, the dimensions of the drainage channel are re-planned because the channel discharge value is smaller than the planned flood discharge value. The results of this study are that the planned flood discharge is greater than the drainage channel water discharge so that the initial channel dimensions cannot accommodate water. The results of re-planning the dimensions of the drainage channel based on the planned flood discharge value are h of 8.5 meters, b of 9.8 meters, and W of 2 meters. Re-dimensional planning of the drainage channel is fulfilled because Qs<Qp (172.634 mᶟ/s <227.103 mᶟ/s). This research is expected to provide dimensions of drainage channels that are in accordance with field conditions so that no more flooding occurs.
Suatu perusahaan konstruksi pada umumnya memerlukan suatu manajemen proyek pada setiap pengerjaan proyek. Hal ini dilaksanakan untuk mendapatkan hasil yang lebih optimal dan waktu yang cepat sesuai dengan yang telah diharapkan, baik untuk perusahaan itu sendiri ataupun pihak owner. PT. Kaliban Bangun Prakarsa merupakan sebuah perusahaan yang bergerak dibidang kontraktor dan sebagai pelaksana dalam pembangunan ruko 3 lantai De Monde Junction. Agar proyek dapat diselesaikan sesuai dengan tenggat waktu yang telah disepakati maka suatu proyek dibutuhkan penjadwalan proyek yang tepat. Tujuan dari penelitian ini adalah membuat anggaran biaya yang akan dikeluarkan, dan penjadwalan dalam pembangunan, serta membandingkan realisasi dari proyek pembangunan ini dengan perencanaan yang telah dibuat. Metode penjadwalan proyek pada penelitian ini dengan mengaplikasikan metode EVA (Earned Value Analysis) yang berdasarkan dari bobot anggaran biaya yang sudah dihitung setelah itu akan dilakukan analisis terhadap realisasi pekerjaan. Dari hasil penelitian ini telah didapatkan bahwa kegiatan konstruksi yang dilakukan pada proyek ini mengalami keterlambatan yang sangat signifikan. Dapat dilihat dari gambar kurva S realisasi yang telah dibuat, dan juga dari perhitungan Planned Value (PV) yang didapatkan sebesar Rp. 20.145.003.680, sedangkan Earned Value (EV) yang didapatkan sebesar Rp. 14.836.795.210,32, sehinggan Schedule Performance Index (SPI) yang didapatkan 0,7365. Hal ini disebabkan oleh beberapa faktor seperti Force Majeure, kurangnya sumber daya, adanya pekerjaan tiang pancang yang belum selesai sehingga terhambatnya proses pembangunan oleh pihak kontraktor.
Smooth transportation conditions can improve population mobility services and other resources that can support economic growth. However, in densely populated cities like Batam, congestion often occurs and causes road users to feel stressed, the pace of the economy is hampered, and a lot of time is wasted. Therefore, it is necessary to review the performance of transportation. The purpose of this study was to determine whether the traffic performance at the Barelang intersection roundabout has been effective against the existing traffic situation in the area. The research was conducted by conducting a traffic survey on the road at the Barelang intersection, Batam to obtain the number of vehicles passing through the Barelang intersection. The reference used in this study is MKJI 1997 with the analysis carried out on road capacity, traffic volume, and degree of saturation. The results obtained at the Barrelang intersection for the road segment from SP Plaza to Muka Kuning has a degree of saturation value of 0.72. As for the road from Muka Kuning to SP Plaza, the degree of saturation is 1.08. Based on MKJI it is determined that the value of the degree of saturation of a road segment should not be more than 0.75, it can be concluded that the road from SP Plaza to Muka Kuning is considered effective and for the road segment from Muka Kuning to SP Plaza it is not effective. The results of this study can be used as a reference in an effort to improve transportation performance.
This research will discuss about Winner Flower housing development The house which will later function as a residence, shop and apartment, and has facilities such as a club house and a swimming pool. This study aims to estimate the time for material procurement based on the time schedule for the construction project of the Punggur Flower House Winner. The method used to determine the estimated time is the conventional method, where the scheduling process is the scheduling process where the measurements are taken, in planning meetings, in measuring, and making scheduling times more regular and systematic. This research will discuss about Winner Flower housing development The house which will later function as a residence, shop and apartment, and has facilities such as a club house and a swimming pool. The estimated work plan for this project is 52 weeks and the realization of this project is 52 weeks. Thus it can be concluded that the processing time until the completion of the work is not delayed.
