Abstract

Banjir yang sering terjadi di Kabupaten Demak disebabkan oleh meluapnya Sungai Dolok. Kondisi Sungai Dolok yang mengalami penyempitan alur serta pendangkalan menyebabkan berkurangnya kapasitas penampang sungai untuk mengalirkan debit banjir. Akibatnya, pada musim penghujan Kabupaten Demak sering mengalami banjir. Sungai Dolok memiliki panjang sekitar 47 km dan luas daerah aliran sungai sekitar 145 km2. Hidrograf banjir Sungai Dolok dianalisis dengan menggunakan program HEC-HMS dan untuk analisis hidrolika menggunakan program HEC-RAS. Hasil analisis menunjukan kondisi penampang eksisting Sungai Dolok tidak mencukupi untuk mengalirkan debit banjir Q50th sebesar 216 m3/dt. Akibatnya, terjadi bencana banjir di Kabupaten Demak. Dari studi dan perhitungan yang telah dilakukan, pemecahan masalah ini adalah mengadakan normalisasi Sungai Dolok dengan melakukan perbaikan penampang sungai Dolok yang sesuai perencanaan. sehingga Sungai Dolok dapat mengalirkan debit banjir dan mengurangi tingkat bencana banjir di Kabupaten Demak.

Abstract

ABSTRACTOne of the Semarang Tanjung Emas flagship facility is a container terminal with field accumulation which is a container handling facility. When viewed from the tendency of the flow of goods through ports, each year has increased. However, an increase in loading and unloading activities are often disrupted by tidal water that flooded dock container terminals. Therefore, the needs of adding  elevation dock container terminals, so that loading and unloading activities are not disrupted. Prior to the adding elevation of the wharf, first geotechnical and structural must be evaluated. From the results of the analysis, geotechnical existing capable of withstanding the load adding elevation dock. Consolidation settlement on geotechnical dock container Semarang is 11 cm, with the consolidation time is 16 months. So the plan elevation of 1.5 m must be added by 11 cm. The decrease was due to land subsidence 11cm/year, so plan elevation of 1.5 m can extend the life of the wharf service to 13 years and 10 months. For existing dock structure able to withstand loads due to the adding elevation of the wharf so it is not necessary to adding capacity. So that the evaluation can be continued into the planning for the elevation of the wharf form of additional beams and plates were riveted by the column.

Abstract

Road of Semarang – Godong is a type of road 2/2 UD currently under repair and greatly affected the result of the open – closed system, so the road was made the object of research. The aim of the research was to analyze the characteristics of the traffic, looking for the relationship between the volume of arrivals – long queues – the length of the work zone and reviewing traffic management system in the work zone. Analyze that done are analyze on existing condition and traffic management system with a length of 1,070 km using the method of the approach to the junction signal with two phases on MKJI 1997. This analysis also simulated on the variant length of the work zone. The results showed an analysis of existing conditions with observations data each cycle can’t proceed, so analysis only use data classification. The system settings can minimize the length of the traffic queues and the degree of saturation. From the results of the simulation of different length work zone obtained a value of DS and the minimum of the queue length 0.2 km. Other results obtained is increasingly large flows of arrival on-site queue getting longer, but the rate of increase in the existing conditions in the queue is larger compared to the results of the analysis of the traffic management system. Further research is required related factors on damage to roads and the length of the segment that is most optimal. To streamline traffic settings can use APILL portable or using more appropriate implementation method.

Abstract

Tujuan studi penelitian ini untuk mengetahui kinerja dan kapasitas dermaga, kinerja dan kapasitas container yard, dan kapasitas alat yang berada di Terminal Peti Kemas Semarang, yaitu Container Crane (CC), Automatic Rubber Tyred Gantry (ARTG) dan Rubber Tyred Gantry (RTG). Metode yang digunakan untuk mengetahui kinerja dermaga adalah Berth Occupancy Ratio (BOR), yaitu perbandingan antara waktu penggunaan dermaga dengan waktu yang tersedia yang dinyatakan dalam presentase. Sedangkan kinerja dari container yard dapat dianalisis menggunakan metode Yard Occupancy Ratio (YOR), yaitu nilai yang  menunjukan persentase dari terminal yang dimanfaatkan untuk penumpukan peti kemas untuk periode tertentu. Kapasitas dermaga dan container yard dihitung menggunakan persamaan kapasitas dermaga terpasang (KDL) dan persamaan luasan container yard (At). Selain itu metode BTP (Berth Throughput) digunakan dalam studi penelitian ini untuk mengetahui tingkat pemakaian dermaga. Nilai BOR dengan persamaan beberapa tambatan pada tahun 2016 adalah 54,33% dan nilai BOR dengan persamaan tambatan umum 22,87%. Besarnya nilai BTP tahun 2016 adalah 3.696 TEUs/m/tahun dan nilai KDL adalah 1.995.640 TEUs. Jika nilai BTP terpasang dibandingkan dengan nilai BTP terpakai (1.139 TEUs/m/tahun) dan nilai KDL dibandingkan dengan jumlah peti kemas tahun 2016 (615.133 TEUs/tahun), maka disimpulkan pada tahun 2016 TPKS  masih mampu melayani kedatangan peti kemas. Luasan kebutuhan Container Yard (CY) dihitung menggunakan persamaan At didapatkan hasil sebesar 17,68 ha. Jika dibandingkan dengan luas terpasang container yard (18,5 ha), maka disimpulkan bahwa container yard TPKS masih mampu melayani penumpukkan peti kemas. Kinerja container  yard di TPKS ditunjukkan melalui nilai YOR pada tahun 2015 yaitu sebesar 62,95%, nilai tersebut dipengaruhi oleh dwelling time. Sebaiknya pada studi selanjutnya didasarkan pada kaidah ISPS Code (International Ship and Port Security) dan memperhitungkan tingkat pertumbuhan industri dan angkutan barang.
