Judul: Port Service Improvement Strategy on Purse Seiner Activities Based at PPI Donggala
Abstrak: Donggala Fishery Port (PPI Donggala) was built as promising local fisheries potential as much as 18.022,7 tons. This port is equipped with various facilities, including a docking area, harbor pool, and other administrative facilities. Those facilities ease fishermen on their fishing activity, from fish landing to product marketing. Pane (2005) and Lubis (2012) explained that there are three main capture fisheries activities in fishing ports: (1) Fish landing, (2) Fishing need supply, (3) Marketing, and (4) Processing activities. One of the main factors that made PPI Donggala exist is Fishing Units called Purseiners. PPI Donggala Purseiners have been calculated 76 units using 10 to 30 Gross Tonnage Fishing Vessel. The ship operates fishing gear with a net length of 300 m to 450 m. The fishing trip is carried out for one day to six days around the Makassar Strait. It has been known by locals that most fishermen that used purse seine want not to land their catch in PPI Donggala. This phenomenon may lead to a decline in PPI Donggala's revenue that comes from retribution fees, ice supplies, and lodge rental for non-local fishermen (from Rp29.525.000,00 in 2016 to Rp25.575.000,00 in 2017. If this happens continuously, it will benefit other ports because the purse seine fishermen in Donggala will pay for mooring services and buy fishing supplies there instead. This activity results in the loss of mooring and business retribution opportunities sales of fishing supplies at PPI Donggala. Therefore, the PPI Donggala needs to identify the reasons for this case and find a way to make PPI Donggala the main port of local fishermen. These research objectives are: 1) identify factors of the absence of local purse seiner at PPI Donggala; 2) identify the technical and operational aspects of PPI Donggala, and 3) Develop a strategy for improving port services on the activities of purse seine fishing units based at PPI Donggala. This research was conducted from December 2019 to January 2020 at PPI Donggala, Donggala Regency, Central Sulawesi. This research using a study case approach. Data was collected from local purse seine fishermen through observation, interview, and literature study. Fishermen and Stakeholders of PPI Donggala were determined as respondents using Purposive Sampling based on the researcher's criteria (Kartikasari 2017) (Mboto et al. 2014). On the other hand, data were collected through accidental sampling that is most easily found or accessed (Perkasa et al. 2016). Data analysis methods are descriptive, comparative, quantitative, and SWOT. The results from identification of factors for not held landing activity of purse seine catch units Donggala, fishermen need 105 m of the dock, 5.719 m and 5,4 m of harbor pool depth and the area, building safety for net repair facilities, 304,000 liters of clean water/month for clean water facilities, 53,200 liters of diesel fuel/month on SPDN facilities, 12.160 blocks of ice/month at the ice factory facilities, boxes and clean water at the hygienic fish auction place (TPIH). The result shows that compared to PERMEN-KP RI NUMBER PER.08/MEN/2012 about Fishery Ports in Indonesia, it is said that PPI Donggala conditions are considered as appropriate. But,

Judul: Optimizing the Utilization of Facilities in Improving Port Operational Functions at PPI Binuangeun Lebak-Banten.
Abstrak: Pelabuhan Pendaratan Ikan (PPI) Binuangeun berperan penting dalam menggerakkan aktivitas perikanan para nelayan di kawasan Binuangeun, Lebak, Banten. Meski merupakan pelabuhan perikanan terbesar di wilayahnya, namun fasilitas yang dimiliki PPI Binuangeun belum dimanfaatkan secara maksimal. Penelitian ini bertujuan untuk mengeksplorasi permasalahan yang terkait dengan kurang dimanfaatkannya fasilitas operasional di PPI Binuangeun. Desain penelitian kuantitatif dilakukan dengan melakukan observasi dan wawancara serta menyebarkan kuesioner kepada pemangku kepentingan terkait yang berperan dalam pemanfaatan fasilitas di PPI Binuangeun. Semua hasil disajikan secara deskriptif. Hasil temuan menunjukkan bahwa kemampuan fasilitas dalam memanfaatkan kapasitas dermaga mencapai 81,8 persen, kolam pelabuhan mencapai 89,9 persen, dan tempat pelelangan ikan mencapai 40 persen, hal ini menunjukkan bahwa fasilitas operasional di PPI Binuangeun berada pada tingkat kelayakan yang memadai. Namun pemanfaatannya belum optimal. Tercatat keseluruhan potensi kerugian keseluruhan dari pemanfaatan fasilitas di PPI Binuangeun mulai dari pelayanan tambat labuh kapal sebesar Rp38.475.000, pelelangan ikan sebesar Rp462.610.000 dan perbekalan es sebesar Rp99.600.000 dengan total keseluruhan Rp600.685.000 per tahun. Hal tersebut tentu dapat menjadi nilai tambah bagi pelabuhan yang tentunya dapat meningkatkan operasional pelabuhan di PPI Binuangeun. Strategi optimalisasi pemanfaatan fasilitas di PPI Binuangeun didasarkan pada SWOT dengan strategi utama yaitu; 1) Meningkatkan kenyamanan fasilitas operasional pelabuhan termasuk dermaga tambat labuh, kolam pelabuhan dan tempat pelelangan ikan (SO1); 2) Pengembangan fasilitas operasional mulai dari pendistribusian hasil tangkapan nelayan ke pasar hingga unit pengolahan perikanan sekitar (SO2); Hasil analisis IFAS memperoleh skor sebesar 3,24 sehingga kekuatan lebih besar dibandingkan kelemahan. Sedangkan skor EFAS sebesar 2,87 atau pada kondisi peluang lebih besar dibandingkan ancaman yang ada. Sejalan dengan hal tersebut, manajemen PPI Binuangeun harus meningkatkan efisiensi operasional pelabuhan, termasuk mengoptimalkan kontribusi pelabuhan terhadap peningkatan industri perikanan dan perekonomian pelabuhan. Langkah-langkah strategis diambil untuk meningkatkan kinerja dan daya saing PPI Binuangeun di masa depan., The Binuangeun Fish Landing Port (PPI) plays an important role in driving the fishing activities of fishermen in the Binuangeun area, Lebak, Banten. Even though it is the largest fishing port in the region, the facilities owned by PPI Binuangeun have not been utilized optimally. This research aims to explore problems related to the underutilization of operational facilities at PPI Binuangeun. The quantitative research design was carried out by conducting observations and interviews as well as distributing questionnaires to relevant stakeholders who play a role in utilizing facilities at PPI Binuangeun. All results are presented descriptively. The findings show that the facility's ability to utilize dock capacity reached 81.8 percent, the harbor pool reached 89.9 percent, and the fish auction site reached 40 percent, this shows that the operational facilities at PPI Binuangeun are at an adequate level of feasibility. However, its utilization is not optimal. It was recorded that the total potential loss from the use of facilities at PPI Binuangeun started from ship mooring services amounting to IDR 38,475,000, fish auctions amounting to IDR 462,610,000 and ice supplies amounting to IDR 99,600,000 with a total of IDR 600,685,000 per year. This can certainly be an added value for the port which can certainly improve port operations at PPI Binuangeun. The strategy for optimizing facility utilization at PPI Binuangeun is based
