Abstract

Shrimp production in several Asian countries, including Indonesia, accounts for more than 85% of world production, thus control of shrimp larval diseases must be strengthened to increase production. This study aimed to test the effectiveness of mangrove leaves, Rhizopora sp, in controlling larval vibriosis of the vannamei shrimp (Litopenaeus vannamei). The study began with in vitro tests to evaluate the antimicrobial activity of mangrove leaf flour against Vibrio sp bacteria at doses of 400, 500, 600, 700, 800, 900, 1000 mg/L, 5% amoxicillin antibiotic (K+) and without mangrove flour (K). In the in vivo test, vannamei shrimp larvae (mysis-3) were immersed in a solution containing mangrove leaf flour with the three best doses of in vitro test results; 800, 900, and 1000 mg/L water, plus K-, for 15 minutes according to the treatment dose and maintained for 8 days before being challenged with Vibrio spp. The parameters observed were total hemocyte count (THC), differential hemocyte count (DHC), and survival rate (SR), which were observed on days 1 and 8, respectively, with the SR parameter observed on day 7 following the challenge test. The results showed that the Mangrove leaf diet at 800 and 900 mg/L significantly improved larval resistance to the pathogen V. harveyi (P < 0.05). The high resistance was triggered by THC immunological response and the high proportion of semi-granular and hyaline at doses of 800 and 900 mg/L (P<0.05). Mangrove leaf powder can therefore suppress vibriosis disease in vanamei shrimp larvae using the immersion method at 800 and 900 mg/L concentrations.

Abstract

Duck is one type of waterfowl that has a higher nutritional content than chicken. The high nutritional value causes the duck meat to be easily damaged perishable food due to the high water content, the pH value is close to neutral and sufficient food is available for microbes. An alternative effort is needed for natural ingredients that are safe but can inhibit microbial growth in duck meat. One of the natural ingredients that can be used is star fruit (Averrhoa bilimbi L.) because it has a high acid content. This study aims to determine the difference in the duration of soaking Magelang duck meat with starfruit juice on the pH value, water holding capacity and water content. The research method was carried out using a completely randomized experimental design (CRD) with 4 treatments and 5 replications, and using a 40% concentration of starfruit juice with a soaking time of 0, 20, 40, 60 minutes. The data obtained were analyzed by analysis of variance and if different results were obtained, it was continued with the Duncan Multiple Rang Test (DMRT) further test. The results showed that the immersion time for 20-60 minutes can lower the pH value (5,83-4,67) and water content (67,05-63,68%), but had no effect on water holding capacity (48,47-54,63%). It is concluded that the immersion time of 60 minutes with starfruit juice with a concentration of 40% in can be used as a method of preserving Magelang duck breast meat.

Abstract

The agricultural sector is vital economic growth; one is by processing agricultural products into valuable products, such as tempeh, from raw soybean materials. The research aims to 1) Describe the characteristics of sellers and buyers of tempeh; 2) Describe the amount of tempeh sold by traders and the amount purchased by consumers; 3) Analyze the factors that affect the demand for tempeh; and 4) Analyze the factors that affect the supply of tempeh. The research was conducted in Pa'baeng-Baeng Market and Terong Market in Makassar City, South Sulawesi. The sample of tempeh traders was 50 people, and the sample of buyers was 200. The analysis methods used were descriptive analysis and multiple linear regression analysis. The results showed that the characteristics of tempeh buyer respondents were 40 years old on average, the average education level was high school (56.82%), the most female gender (83.64%), and predominantly worked as housewives (46.81%). The characteristics of tempeh trader respondents based on age are an average of 41 years, an average high school education level, and the dominant gender is male (74.00%). The average tempeh purchased by consumers is 19 packs/month, and the average tempeh sold is 3,504 packs/month. Simultaneously (F-test) is significant to the demand for tempeh, with a coefficient of determination (R2) of 62.1% that have a significant effect partially (T-test) are all the variables tested, namely the price of tempeh, buyer income, number of family dependents, intensity of need, taste, and price of substitute goods. F-test is significant to the supply of tempeh, with a coefficient of determination (R2) of 60.3%. The significant factor of effect partially (t-test) on the supply of tempeh are the price at the producer level, future price expectations, the number of producers, and the number of consumers. Meanwhile, the price at the trader level is insignificant

Abstract

One way to get rice that can adapt to drought stress is by providing drought tolerance in the germination phase through seed invigoration with the “Seed Priming” method. The study aimed to determine the level of adaptation and the response of growth and production of PEG-primed rice under drought-stress conditions.  The research was conducted in two stages. Phase I was in the form of rice seed priming in PEG 6000 solution arranged in a Randomized Group Design (RAK), consisting of 5 treatments, namely treatment without priming as control, PEG priming 0 gL-1, 50 gL-1, 100 gL-1, and 150 gL-1 with the length of seed priming for 36 hours. Phase II was a priming test of production levels in the field from the selected treatments in Phase I. The data were then statistically analyzed using analysis of variance (ANOVA). The results showed that priming treatment using PEG 6000 for 36 hours with a concentration of 100 gL-1 gave the best results on vegetative growth (93% germination, seedling height 28, 27 cm, leaf length 19.11 cm, number of leaves 4 cm, and root length 4.08 cm). This concentration also gave the best results on generative growth (number of productive tillers 12, and grain weight 31.71 per clump), and increased the adaptation of paddy rice to drought stress conditions.
