Nursinah Amir — 2024-06-09

Catfish (Pangasius sp.) has high nutritional value and can be used to make various products, one of which is jambal roti. This research aims to determine the characteristics of jambal bread based on fermentation time and salt concentration. The research used an experimental method with a completely randomized design (CRD) factorial pattern with three levels of fermentation duration (A), namely A1:24 hours, A2:36 hours and A3:48 hours at two levels of salt concentration (B), namely B1:25% and B2:30% repeated 3 times. The parameters assessed are sensory characteristics, total plate number, water content, ash content and salt content. The results showed that the sensory values were appearance (7.82-8.30), smell (8.14-8.25), taste (8.04-8.41), texture (7.66-8.68), mold (9.00). The research results also showed total plate number (0-1.037 x 103), water content (26.99 - 32.29%), ash content (18.98 - 23.34%) and salt content (19.44 - 24,50%). ALT meets standard quality requirements (SNI 2721.1-2009), water content complies with SNI (8376:2017), ash content does not meet the SNI (8376:2017), and salt content in 2 samples (A1B2 and A2B2) only meets SNI (8376:2017). The characteristics of Catfish Jambal Roti Patin this study, in general, are in accordance with SNI (8376:2017)

Sellers in this market earn an average income per day of Rp 1,500,000 – Rp 2,000,000 with 4-6 years of sales experience. The results of marketing mix research applied to the Jatinegara Ornamental Fish Market can be seen from the 7P point of view, namely 1) The results of the marketing mix in products include product diversity and types of packaging for transporting ornamental fish, 2) The results of the marketing mix in prices include price variations and causes of price variations, 3) The results of the marketing mix carried out include sales locations that are narrow land and no parking space is available, 4) Physical evidence include product arrangement and product information on display, 5) The results of the marketing mix in people include informative seller attitudes, 6) Promotion includes promotional media, 7) The process includes payment methods and receipts.

Development Center of Minapolitan Area in Wajo District

Yashinta Kumala Dewi — 2024-06-09

Regional development with a Minapolitan concept is part of the marine and fisheries industrialization policy strategy which aims to realize accelerated increases in the income of cultivators, fishermen, processors, and marketers by integrating upstream and downstream production systems to increase the scale and quality of production, productivity, competitiveness and added value for sustainable marine and fisheries resources. The Minapolitan program is designed to increase the competitiveness of fisheries commodities which is then targeted to increase regional competitiveness and reduce the gap between urban and rural areas. This activity is intended to formulate a development center for the Minapolitan area of Wajo District which will become the basis for preparing technical work plans for related agencies. Based on field results, it was found that the marine and fisheries resource potential of Wajo District was mapped into two resource potential zones, namely (1) the coastal subdistrict area (Bola, Takkalalla, Sajoanging, Penrang, Keera and Pitumpanua subdistricts) which is directly connected to the waters of Bone Gulf for the utilization of potential resources of capture fisheries and aquaculture (marine cultivation and pond cultivation); and inland fisheries areas, especially in the Tempe lake area (Sabangparu, Tempe, Tanasitolo and Belawa subdistricts). Utilization of the potential of the coastal areas of the District of Wajo, with its characteristics of an open water area directly bordering Gulf of Bone, has more potential for the development of capture fisheries, marine aquaculture, and brackish/pond cultivation with the superior commodities of seaweed and mangrove crabs as well as coastal ecotourism. Meanwhile, the Tempe Lake area is more geared towards fishing, cultivating freshwater fish and limited area management for ecotourism activities.

The Effect of Adding Thyroxine Hormone (T4) to Commercial Feed on The Growth Profile of Pompano (Trachinotus blochii, Lacapede)

Indarwati Indarwati — 2024-06-09

The purpose of this study was to analyze the effect of adding commercial feed with various concentrations of the hormone thyroxine (T4) on the growth profile of star pomfret (T. Blochii, Lacapede). This research was conducted for 50 days at BPBL Sekotong. The method used is an experimental method with a completely randomized design (CRD) which includes 4 treatment levels and 3 replications. consisting of: P1: control (without thyroxine hormone), P2: thyroxine hormone 1 mg/kg feed, P3: thyroxine hormone 1.5 mg/kg feed, P4: thyroxine hormone 2 mg/kg feed. Parameters measured were absolute weight, absolute length, specific growth rate (SGR), feed efficiency (EP), feed conversion ratio (FCR), survival (SR) and water quality. Data were analyzed using variance (ANNOVA) and continued with Duncan's test. The addition of the concentration of thyroxone hormone (T4) in commercial feed can affect the growth of star pomfret but does not affect the value of feed utilization efficiency (EPP), feed conversion (FCR) and survival (SR). The addition of the concentration of thyroxine hormone (T4) 2 mg/kg in commercial feed is the best treatment in star pomfret culture, because it can provide an absolute weight of 7.69 g, an absolute length of 3.50 cm, and a specific growth rate of 2.28%/day.

A Review on Chicken Feather Flour Potential for Fish Feed

Yuli Andriani — 2024-06-09

The escalating demand for chicken meat over the years has led to a corresponding increase in waste generation, particularly chicken feathers. While efforts such as making dusters and cocks have been undertaken to address this issue, they have yielded limited success in effectively managing chicken feather waste. Given the significant levels of nutrients, including protein and amino acids, present in this waste, it holds immense potential as a raw material for fish feed. However, the utilization of chicken feather waste remains relatively uncommon due to the challenging digestibility of its large crude protein structure, primarily composed of keratin protein. Thus, preprocessing is essential to degrade the keratin within chicken feathers, rendering it digestible for fish. This review aims to provide an overview of the potential utilization of chicken feather meal in aquaculture, particularly in fish feed formulations, by exploring its nutritional value and various processing methods to enhance the quality of this raw material.
