Abstract Palabuhanratu Fishing Port is one of the centers of fisheries activities which are currently in the stage of planning to upgrade the status of Ocean Fishing Port. Provision of good facilities and quality services is the most important thing in supporting these activities.However, the problems that exist in fishing ports have been the low level of operation and service of fishing ports caused by internal and external factors of the fishing port. This research was conducted to calculate the operational performance of the fishing port by observing operational activities and fishermen's satisfaction with port services. This research was carried out in May 2018 at the Palabuhanratu Fishing Port, Sukabumi Regency, West Java Province.The results of the analysis carried out showed that the operational performance of Palabuhanratu was included in the category of good enough with a value of 2.72.The achievement of this value is supported by the number of production and frequency of ship visits, each of which has 72.20% and 90.84% success rates, while for the provision of facilities and low service quality, with an average of 16%.This shows that further development of Palabuhanratu must pay more attention to the provision of facilities and quality of service. Keywords: Fisherman Satisfaction, Performance, Operational, Fishing Port

Abstract Thynnichthysthynnoides is commonly inhabit the Bunter Lake. A research aims to understandthe growth rateof the fish in the Bunter Lake has been conducted in April-May 2019. The method used in this study is a survey method in which the waters of Lake Bunter as a research location. The fish was sampled everyday for24 days, using gillnets. The fish that are taken from the smallest to the largest, which represent each size and weight of the fish.Results shown that theasymptotic length ((L∞) 20.11 mm, growth coefficient (K) 0.74/year, and t0 -0.2426/year. It means that the growth of fish in Lake Bunter takes 6 months to reach an asymptotic length value. Results shown thatthe water quality of the Bunter Lake are as follows temperature 29-30oC, tranparancy40-65 cm, depth1,80-9,10 M, pH 9 and dissolved oxsygen3,8-4,4 mg/L. Water quality in the Bunter Lake is able to support the life of T. thynnoides.    Keywords :Oxbow lake, growth coefficient, water quality,growth, asymptotic length

Abstract

ABSTRACTGeographical Information System (GIS) method is one of the methods that began to be used and developed in Indonesia in observing and analyzing spatial changes in an area. The study was conducted in March - April 2019 in Central Tapanuli Regency, North Sumatra Province. The purpose of the study was to analyze changes in land cover of mangrove vegetation and mangrove vegetation index based on images taken from different times at intervals of 5 years, namely from 1998 to 2018, the category of density obtained in the field was analyzed based on Minister of Environment Decree No. 201 of 2004 concerning Standard Criteria and Guidelines for Mangrove Damage Determination. The results showed that environmental ecological conditions support the existence of mangroves. Morphological identification was obtained by 11 species from 8 families of mangrove vegetation. The area of mangrove vegetation in 1998 was 9510 ha and the area of mangrove in 2018 was 1,779 ha. Over a period of 20 years (1998 - 2018) there was a change in the reduction in the area of mangroves covering an area of 7,731 ha, with a total of 81% of mangroves lost during the last 20 years. Tree density calculation data at 3 stations are 1622 ind / ha, 1,444 ind / ha and 2,133 ind / ha in the meeting category at station I and III and medium at station II. Puppies density at 3 stations namely 4,355 ind / ha, 6,444 ind / ha and 4,400 ind / haKeywords: Central Tapanuli Regency, Mangrove, Changes in Area, NDVI,Density.

Abstract

ABSTRACT This research was conducted on April-May 2018 in the Kualu Nenas Village, Tambang District, Kampar regency, Riau Province. Objective of study was to determine the effect of different biomass A. microphylla on increasing chemical parameters of water on peat soil. The method used in this study is an experimental method using a Complete Random Design (CRD) with 1 factor, 4 treatments and 5 replications. The treatment used in this experiment are P0 (without biomass of Azolla michrophylla ), P1 (biomass Azolla michrophylla 20 g/m2), P2 (biomass Azolla michrophylla 40 g/m2) and P3 ( biomass Azolla michrophylla 60 g/m2). The water quality parameters measured in this study are, pH, dissolved oxygen, CO2, nitrate and phosphate.The results showed that biomass of Azolla microphylla  had a significantly different effect on changes in chemical parameters of water on peat soil media. The best results that can improve the chemical parameters of peat water are found in the treatment of Azolla michrophylla 20 g / m2 (P1) by increasing the pH value (6.2); Dissolved oxygen (6,64 mg/L); Nitrate  (17,72 mg/L) and phosphate (3,31 mg/L). Except for CO2 concentration found in treatment P3 (Use of bimasa A. michrophylla 60 g / m2) which is 21.9 mg / L. Keyword : Azolla michrophylla, chemical parameters, Peat soil

Abstract

ABSTRACTThe research was conducted in the village of Canang Kering XX Belawan, North Sumatra Province. The purpose of this study was to determine the effect of adding lime water mixed with spinach extract in feed for survival, growth rate, and accelerating the time of moulting mud crab (Scylla serrata).This research was conducted using Experimental Methods with completely randomized design (CRD), those is 5 treatments and 3 replications. P0 (without giving CaO and extract spinach), P1 (Provision 4 ml of CaO and 30 g of spinach extract), P2 (Provision 4 ml of CaO and 35 g of spinach extract), P3 (Provision 4 ml of CaO and 40 g of spinach extract), P4 (Provision 4 ml of CaO and 45 g of spinach extract).Animal testing used was mud crab (S. serrata) with an average initial weight of ±100 gr / individual. Animal testing used were 60 crabs and maintained in a plastic basket measuring (59 x 37 x 17 )cm3during 60 day. The results shows different feed percentages had a significant effect (P <0.05) on absolute weight growth, feed conversion, livelihood, moulting, but not significantly influence (P> 0.05) on SR mangrove crabs. The results showed that the best treatment for absolute weight growth was in the administration of 4 ml of lime water and 40 g of spinach extract of biomass weight (P3) which was 189.67 g, specific growth rate of 3.27%, Best feed conversion  is 7.55, and an average of 18.66 days molting time with a survival rate of 91.33%, Keywords : Mud crab, limewater,Spinach , Moulting, Growth, Life-long rate

Abstract

ABSTRAKThis research was aimed at knowing the role of fisheriesextension and the effectiveness of the extension, and also the problem that faced by the fisheriesextension at Subdistrict Kampai Tabu Karambie. The data of this research was primer and sekunder. The sample of this research was 2 fisheriesextension and 14 member of  minapadi paktikah group. The data is analized by  skala likert and descriptive qualitative. The result of the research shows that the role of the extension as the inisiator, motivator, fasilitator, mediator and supervisor was in good category, it proved by the score 910, it shows that the role of the fisheriesextension to the minapadi paktikah group was delivered well. In the other hand, the effectiveness that being scored by effective, satisfy, adaptation, organization, was in good category with score 437, shows that the fisheriesextension was done their job and understanding by the fish farmer. The problem during this research is the extension was not balance with the group of the fisheries business, so the material was not delivered well. Keywords :Fisheries Extension, Kampai tabu Karambie, Minapadi, Role
