Seaweed jelly candy is a popular food product with a characteristic chewy texture and sweet taste, but it is very susceptible to quality degradation because it is semi-wet so it is easy for microorganisms to grow. This research aims to determine the effect of adding red ginger extract on the physical and microbiological characteristics of seaweed jelly candy. The research method used is an experimental method with four treatments with three replications adding concentration of red ginger extract (0%, 20%, 35% and 50%) based on the weight of the seaweed used. The parameters observed in this research are physical characteristics (Texture Profile Analysis / TPA) and microbiological characteristics which include, gumminess, gel strength, adhesiveness, springiness, cohesiveness, chewiness and total mold. Total mold testing was carried out using the duplo method and referring to SNI 2332.07 in 2009. Texture Profile Analysis/ TPA testing was carried out using Completely Randomized Design (CRD). Based on the research results, it can be concluded that the addition of red ginger extract has an effect on the physical and microbiological characteristics of seaweed jelly candy. The best treatment with addition of red ginger  extract  to  the  physical  and  microbiological  characteristics  of  seaweed  jelly candy is treatment D (addition of red ginger extract 50%), with gumminess value of 128.87%, gel strength 468.26 gforce, adhesiveness -0.053%, springiness 0 .83%, cohesiveness 0.16%, and chewiness 107.75%, and the total value of mold is 2.46.

The biological aspect is a piece of basic information that is commonly presented in assessing the level of environmental friendliness of fishing gear or fishing vessel. This study was conducted to analyze the biological aspects of the main catch of the troll line at the Palabuhanratu Fishing Port, Sukabumi, Indonesia. The biological aspects analyzed consisted of length frequency distribution, length-weight relationship, to the average feasibility status of the caught target fish. There were three main target commodities for fishing from the troll line that was identified during the research activity, namely yellowfin tuna (Thunnus albacares), skipjack tuna (Katsuwonus pelamis), and frigate tuna (Auxis thazard). A total of 14 troll line fleets were obtained as a source of research data based on the accidental sampling method. The total number of 1404 fish consisting of 480 yellowfin tuna, 475 skipjack tuna, and 449 frigate tuna were obtained as research data objects. The stratified random sampling method was used in determining the observed sample fish data. Yellowfin tuna were distributed at size 29 – 148 cm, skipjack tuna at size 29 – 88 cm, and frigate tuna at size 23 – 82 cm. Analysis of the length-weight relationship showed a negative allometric growth pattern in the three main fishing target commodities. The analysis of the feasibility of the average fish caught based on compared of L50% to ½ L∞ shows that the average size of tuna and frigate tuna caught is undersize for catching, while the average skipjack caught has reached a legal size. The results of this study indicate that there is a need for a review of the use of fishing hooks in the fishing activity of the troll line fishing fleet. Increasing the hook size can be used to avoid catching fish that are at a size that is not suitable for catching.

This study has the aim to analyze the competitiveness production of floating net cages aquaculture in West Java Province. The research was conducted from September 2020 – July 2021. The method used was a literature survey to determine the competitiveness of floating net cage aquaculture in 27 regencies/cities in West Java Province. Data collected was analysed descriptively. Primary data is in the form of expert judgment consisting of 20 people regarding the proportion of competitiveness of floating net cage aquaculture fisheries. Secondary data on Floating Net Cage Aquaculture Fisheries (2004 – 2019) was obtained from the office of Maritime Affairs and Fisheries of West Java Province.The results of this study indicates that the regencies with very high competitiveness are Purwakarta Regency and Cianjur Regency. While the regencies with low competitiveness are regencies/cities in the northern and southern regions.

Cirata Reservoir is one of the three cascade reservoirs fed by the Citarum Watershed with an area of ​​62 km2 (6.200 ha) and has a water volume of 1.900 million m3. The great potential of the waters in the Cirata Reservoir is utilized by the local community as a source of livelihood, namely by conducting aquaculture activities using floating net cages (FNC) in excess. FNC is thought to be a source of waste that reduces reservoir water quality. This research aims to determine the impact of FNC cultivation on primary productivity with different FNC densities at each station. The research was conducted in Cianjur Regency by taking on three stations, namely in the areas of Jangari, Maleber, and Patok Beusi on November 6 - December 8, 2019. The method used in the research was purposive sampling then analyzed in detail and quantitatively. The results show that reservoir waters have an average of physical parameters, namely temperature 32.2-32.6oC, transparency 0.59-0.68 meters, pH 7.1-7.3, carbon dioxide 15.4-16.1 mg / l, Dissolved Oxygen 6.9-7.3 mg / l, Biochemical Oxygen Demand 6.1-7.8 mg / l, nitrate 0.208-0.222 mg / l, ammonia 0.002833-0.003056 mg / l, phosphate 0,165-0,167 mg / l and primary productivity 240,36-277,90 mgC/m3/hour. This shows that the water indicator is still classified as good because it does not exceed the water quality standard.

Fish bones are a wasted and unused product though it contains high minerals, especially calcium and phosphorus, so that fish bones can be used as raw materials for making bone powder. The manufacture of pangasius bone powder generally goes through a heating process that aims to remove fat from the bones and can denature the protein. The physicochemical characteristics of pangasius bone powder greatly determine the use of the product and are related to the quality of the product. The physicochemical characteristics consisted of yield, bulk density, water content, ash content, fat content, protein content. The main potential of pangasius bone powder is as a source of calcium and phosphorus in meeting mineral needs for the body.
