Promotion is important in marketing activities, especially in increasing traffic, known as online promotion. Along with the development of increasingly sophisticated technology, the internet is no stranger to marketing a product. An effort to sell a product or service using Internet media can also be called e-marketing. This study aimed to know the effect of promotion through instagram on purchasing decisions for processed fish products at Dakon Frozen Food Sleman, Yogyakarta. The quantitative data of this study are questionnaires distributed to consumers of Dakon Frozen Food Yogyakarta. The sample used in this study were instagram users, with a sample size of 40. The data sources used are primary data and secondary data. The data collection technique used was distributing questionnaires. The data analysis techniques researchers use are simple linear regression, validity test, reliability test, normality test, linearity test, simple linear regression test, correlation coefficient test, determination coefficient test, and hypothesis testing. The results showed that the simple regression analysis equation obtained was Y = 11.242 + 0.756X + e. Instagram promotion (X) significantly influences the purchasing decision variable (Y), with a coefficient of 11.242. In testing the hypothesis using the t-test, the t-count value of the Instagram promotion variable is 11.242> from the table, which is 2.026 and a significant value of 0.000 <0.05. This means that H1 is accepted, namely: There is an influence of Instagram promotion on purchasing decisions for processed fish products at Dakon Frozen Food Sleman, Yogyakarta

Nutritional Contents of Catfish (Pangasius Sp.) Jambal Roti Products Sidenreng Rappang Regency, South Sulawesi

Mon, 29 Apr 2024 00:00:00 +0000

Catfish (Pangasius sp.) is a popular type of freshwater fish that has the potential to be cultivated in Indonesia. So far, the use of catfish, especially those from Sidenreng Lake, Sidenreng Rappang Regency, South Sulawesi, has not been optimal. Catfish is only used as a fresh commodity without processing and preservation activities. One of the well-known preserved products is jambal roti. Jambal roti is a product of salt fermentation. This research aims to analyze the nutrition contents of jambal roti catfish, Sidenreng Rappang Regency, South Sulawesi. The research method used was experimental with a Completely Randomized Research Design. The treatment was long fermentation (24, 36, and 48 hours) at a salt concentration of 30%. The parameters observed were water content, salt content, protein, fat, and amino acids. The research results showed that the treatment given significantly affected water content, salt content, protein, fat, and amino acids. The best treatment is a fermentation period of 36 hours.

Mollusc has great commercial benefits in capture fisheries and aquaculture. However, it can also cause economic losses and human suffering. Some macrozoobenthos of the mollusc species are intermediate hosts for parasites and pests in aquaculture pond systems. The reservoir in the pond is a sedimentation area and a biofilter to optimize water quality before flowing into the pond. This study aims to analyze macrozoobenthos community structure at the ecoshrimp reservoir pond located in Waetuoe Village, Lanrisang District, Pinrang. Macrozoobenthos sampling was carried out using a 1x1 m quadrant-transect. The results showed that the identified molluscs consisted of eight species grouped into four families and two classes, including Gastropods and Bivalves. The abundance of macrozoobenthos at the pond's edge was smaller than those in the middle part (994 individuals vs. 1095 individuals). Sermyla requtii was the species with the highest density of 350 ind/m2 at the edge and 670 ind/m2 in the middle of the reservoir. The frequency of occurrence of macrozoobenthos at both observation sites has a value of > 25%. The diversity index at the edge of the reservoir (1.7015) and in the middle of the reservoir (1.2533) is relatively moderate. The uniformity index value at the edge of the reservoir (1.8620) and in the middle of the reservoir (1.3715) is relatively high. The dominance index value at the edge of the reservoir (0.2192) and in the middle of the reservoir (0.4124) is relatively low. The particle size analysis shows that the sediment type in the reservoir is medium sand with an average median value (d50) of 0.29 mm.

Impact of Moon Phases on Purse Seine Fishing Yields in Bulukumba Waters

Tue, 14 May 2024 00:00:00 +0000

The activity of small pelagic fish is influenced by light, so changes in the moon phase will impact the distribution of fish, especially small pelagic fish. Therefore, this research aims to determine the concentration of fish based on lunar phases and explain the composition and frequency of fishing based on lunar phases in Bulukumba Regency. This research aims to provide information to fishermen to determine potential fishing areas. Data was collected in Bulukumba from July to September 2020 following 28 fishing trips using purse seines. The data used are primary and secondary. Primary data consists of the type and number of catches grouped based on lunar phases, namely dark, dark-to-light, light, and light-to-dark periods. Secondary data was obtained from interviews and literature studies. The data analysis used calculates the composition and frequency of catches. The results showed that there were eight types of fish caught during the research. The types of fish most commonly seen are trevally (Decapterus spp), yellow trevally (Selaroides sp), and mackerel (Rastrelliger spp). The highest catch frequency of these three types of fish occurred during the light-dark and light-dark periods.

A Review of The Effectiveness of Fish Aggregating Devices (FADs) in Indonesian Waters

Muhammad Afrisal, Masrurah Ismail, Ahmad Yani — Tue, 30 Apr 2024 00:00:00 +0000

The utilization of Fish Aggregating Devices (FADs) in fisheries represents one of the most attractive and effective methods for increasing fishermen's catches. This review article aims to evaluate the use of FADs in enhancing sustainable catch outcomes and considers their role as an effective management tool. Various types of FADs have been designed and developed across different waters in Indonesia. There are several types of FADs commonly observed, including Squid FADs, Bio FADs, Sea urchins FADs, Electronic FADs, Bamboo raft FADs, Coconut leaf attractor FADs, Palm fiber attractor FADs, Light attractor FADs, FADs palm midrib, Rafia rope attractor FADs, Lubuk larangan FADs, and Fiber FADs. This paper reviews the different types of FADs, considering aspects such as the catch produced, technical specifications, and economic factors. Among these, portable FADs constructed from coconut leaves and raffia lines as attractors emerge as particularly effective and commonly used in Indonesian waters. FADs are also often combined with lift nets or electric fish attractors to enhance their effectiveness. Environmentally friendly fishing gears such as handlines and fishing rods are commonly operated around FADs. The types of fish caught typically include a mix of small and large pelagic species.
