Abstract

Wilayah pesisir Kota Cilacap memiliki peran penting dalam peningkatan perekonomian warga Cilacap. Salah satunya adalah industri energi yang berada di wilayah pesisir Cilacap. PLTU Adipala berperan penting sebagai penyedia listrik untuk seluruh area Jawa Tengah. Karena lokasi PLTU yang berada di wilayah pesisir, menimbulkan berbagai macam permasalahan. Salah satu permasalahan yang terjadi adalah adanya sedimentasi di daerah dermaga dan alur pelayaran PLTU Adipala. Hal tersebut mengakibatkan terganggunya proses pengiriman batu bara. Selain itu adanya gelombang laut yang besar juga menyebabkan terganggunya laju kapal yang ingin menuju dan meninggkalkan area dermaga PLTU Adipala. Oleh karena itu perlu dilakukan kajian mengenai fenomena perubahan morfologi untuk mengetahui penyebab permasalahan dan solusi yang perlu diterapkan untuk mengatasinya. Penelitian yang akan dilakukan yaitu dengan melakukan simulasi pergerakan pola gelombang dan transport sedimen pada perairan di sekitar PLTU Adipala. Hasil pemodelan kondisi eksisting selama 1 bulan menunjukkan volume sedimen di kolam labuh saat musim barat sebesar 271.947 m3, sedangkan hasil pemodelan setelah adanya bangunan groin menunjukkan volume sedimen di kolam lauh PLTU sebesar 46.529 m3. Pada model yang disimulasikan pada musim timur selama 1 bulan dengan kondisi eksisting menunjukkan volume sedimen di kolam labuh PLTU sebesar 56.027 m3, sedangkan hasil pemodelan setelah adanya bangunan groin menunjukkan volume sedimen di kolam lauh PLTU sebesar 46.984 m3. Berdasarkan hasil dari simulasi model di kolam labuh PLTU menunjukkan pengurangan sejumlah volume sedimentasi karena adanya bangunan groin.

Abstract

Fishing is a fishing activity that has been around for a long time. Fishing is done to fulfill human needs. Based on existing data, Indonesian people's consumption of fish reaches an average of 41 kilograms per capita per year, in other words, it is still very low. One of the causes is the lack of productivity of fish catches. Fishing is dominated by large vessels with modern equipment, so the fishing capacity of traditional fishermen is very low. The Ministry of Maritime Affairs and Fisheries is trying to increase fishing productivity, one of which is by providing fishing deck machinery to small fishermen. The problem is that fishing aids are imported products and require maintenance which is not easy and not cheap. Based on this, a fishing tool that is more efficient and easy to maintain and operate is designed. The process of fishing aids uses a buoy equipped with AIS. The purpose of the buoy frequency for calling fish is equipped with AIS which is used to detect the position of the buoy for 2 to 4 days when the ship will come to take the buoy. It is installed on the buoy, namely to maintain security and call fish. The signal from the buoy uses the frequency on the buoy which is used to catching fish is also to detect other ships that will approach to catch fish and where there are lots of fish. The Ulrich and Eppinger method with the mission of fishing aid products can be made by local industry. Based on the results of the product concept design for fishing aids, the 1st (one) variant concept was chosen with specifications, namely: (1) tool dimensions 500 mm x 150 mm x 225 mm; (2) a drive system with low electrical power using a large reducer rotation; (3) has 2 (two) manual functions and functions

Abstract

The strategy of sea transportation in an effort to reduce logistics costs from the tugboat side so as to produce logistics costs that are able to create an increase in the competitiveness of national products. One of a series of services at the port, the implementation of pilotage services is one that is important to get attention because it is the first and last service provided to ships that will visit and depart from the port. Good management of tugboat services will help speed up ship services, maintain order, safety and security in the port environment, because when we talk about waiting time, we are talking about excess costs that will be incurred. This research is expected to see and learn about the loading and unloading system at PT. Putra Segara Abadi which focuses on what factors affect Waiting time which results in additional costs. The results showed that there was a positive and significant effect between Demurrage on Waiting Time (t count value of 2,013 > t table value of 1,98472), The results of the multiple linear regression equation showed that there was a positive and significant influence between Dwelling Time on Waiting Time (value t count of 2.289 > t table value of 1.98472), The results of the multiple linear regression equation indicate that there is a positive and significant influence between Human Resources on Waiting Time (t count value of 5.373 > t table value of 1.98472)
