Abstract

Research on the application of fruit waste liquid organic fertilizer to the growth of pakcoy plants (Brassica rapa L.) has been carried out. The purpose of this study was to determine the growth response of the pakcoy plant (Brassica rapa L.) to the application of liquid organic fertilizer from fruit waste at various concentrations hydroponically and to determine the best concentration of liquid organic fertilizer for the research results. The design of this study used CRD (Completely Randomized Design) with experimental data collection methods. This research was conducted with one control treatment, 5 treatments and 4 replications namely D0 (100% AB mix), D1 (25%), D2 (40%), D3 (55%), D4 (70%) and D5 (85%). Data were analyzed statistically through ANOVA test and followed by 5% DMRT test. Based on the research results obtained, the application of liquid organic fertilizer from fruit waste had a significant effect on the growth response of pakcoy plants (Brassica rapa L.). This can be seen in the best treatment found in treatment D5 (85%), as evidenced by the highest average result of fruit waste liquid organic fertilizer at plant height: 22.075 cm, number of leaves: 20.25 leaves and fresh weight: 41. 25 gr/plant. Thus, the use of fruit waste as a POC affects the effectiveness of pakcoy growth.

Abstract

The high mortality or death during the transportation process is caused by the fact that catfish fry are stress-prone fish and have fast metabolism. Handling the problem of high mortality in the process of transporting catfish seeds requires alternative probiotics from banana stems because banana stems contain saponins, flavonoids, alkaloids, and tannins. This study aims to determine the effect of giving probiotics from processed banana stems to increase the survival of catfish seeds in the 6-hour transportation process, the study used a randomized block design (RBD) with 4 treatments, namely giving fermented banana stem probiotics (T1), banana stem probiotics without fermentation (T2), commercial probiotics (T3), without probiotics (C) with 3 repetitions. The results showed that giving banana stem probiotics had an effect based on the ANOVA test of 0.00 <0.05 and in Duncan's test there was a significant difference in each treatment. In the study the effect of probiotics was seen from the still ideal water quality, fish behavior during the transportation process and survival rate (SR). SR of each treatment was (T1) 90%, 86%, 84%, (T2) 98%, 98%, 96%, (T3) 88%, 90%, 84% , (C) 20%, 28%, 20%. Giving probiotics from processed banana stems without fermentation (T2) had the best effect on the survival of catfish seeds in the transportation process.

Abstract

One of the most popular freshwater fish species to farm, both domestically and internationally, is the koi fish (Cyprinus Rubrofuscus). However, koi fish farming is often attacked by bacterial diseases caused by the Aeromonas hyrophila bacterium, so it becomes a concern because this bacterium can cause death in koi fish. Papaya leaves were chosen as an alternative medicine in the treatment of koi fish infected with bacteria, considering that papaya leaves contain many compounds that are antibacterial and have no side effects when used. As for this study, the papaya leaves used were young papaya leaves which were extracted using the maceration method. This study was aimed to determine the effectiveness in treating koi fish infected with bacteria and what concentration of papaya leaf extract is effective as an antibacterial to treat koi fish seeds that are attacked by Aeromonas hydrophila bacteria. Papaya leaf extract was administered at different concentrations, namely 0 ml (control), 5 ml, 10 ml, 15 ml within 30 days before and after the koi fish seeds were attacked by Aeromonas hydrophila. The result revealed that papaya leaf extract has effectiveness as an antibacterial which can slow down the growth of Aeromonas hydrophila bacteria at a concentration of 15 ml with a survival rate of 95%. Therefore, the dose of papaya leaf extract is directly proportional to its effectiveness as an antibacterial. In other words, the greater the dose of papaya leaf extract, the more effective it will be in treating koi fish seeds that are infected with bacteria.

Abstract

Tilapia nuggets are an instant food with high protein and mineral content. Adding tapioca flour to the nuggets increases gel rigidity when cooling, making the texture harder. However, to optimize the nutritional value and texture of tilapia nuggets, seaweed can be added. This study aimed to determine the best formulation for tilapia nuggets that meet SNI 7758 quality standards. Research methods included observation, literature study, questionnaire, and experiment. The results show that substituting Eucheuma Cottonii seaweed for tapioca flour significantly improved sensory, physical, and chemical test parameters. The best formulation, N1, with an effectiveness index value of 77.1, met the quality standards of SNI 7758. It received an appearance score of 7.73, odor score of 7.40, taste score of 7.73, texture score of 7.33, texture hardness of 666 gr, water content of 59.95%, ash content of 2.31%, protein content of 13.94%, and fat content of 0.76%. Therefore, adding seaweed to the formulation of tilapia nuggets can enhance their nutritional value and texture.

Abstract

Betel leaf has a long history of use in traditional medicine due to its natural antibacterial properties. This study focuses on the antibacterial effects of betel leaf (Piper betle) extract, particularly against Aeromonas hydrophila infections in koi fish. The research employs an experimental approach using a Completely Randomized Design (CRD) with four treatment groups, each repeated twice. The treatments consist of: a control group (Treatment K) without betel leaf extract, Treatment A with 5 ml of betel leaf extract, Treatment B with 10 ml of betel leaf extract, and Treatment C with 15 ml of betel leaf extract. The results of the study demonstrate the significant efficacy of betel leaf extract in promoting the healing of Aeromonas hydrophila-infected fish. This is evident from observations of reduced wound diameter in fish treated with betel leaf extract. In Treatment A (5 ml dose), noticeable wound diameter reduction begins in the fourth week. Treatment B (10 ml dose) shows similar progress with visible healing in the third week. Treatment C (15 ml dose) exhibits the most promising results, with wound diameter reduction or fading evident as early as the second week. Survival rates are recorded as follows: Treatment K – 50%, Treatment A – 65%, Treatment B – 75%, and Treatment C – 90%. These findings underscore the potential of betel leaf extract as an effective antibacterial remedy in combating Aeromonas hydrophila infections in koi fish.

Abstract

Bawal fish is popular in many Asian cuisines and is often served grilled, fried, or steamed. It is known for being a good source of protein and essential nutrients, making it a healthy and nutritious option for seafood lovers. Meanwhile, fermented Azolla flour contains high levels of nutrients, such as protein, vitamins, and minerals, which can help improve fish growth. The nutrients in the fermented Azolla flour can be utilized by the fish to build body tissues and accelerate body mass growth. The aim of this study is to evaluate the impact of using fermented Azolla microphylla flour in artificial feed for the growth of bawal fish fry and the best percentage of fermented Azolla microphylla flour in the feed to enhance fish growth. The study used a completely randomized design (CRD) with 1 factor, 5 treatments, and 2 replications. The treatments in this study were PA (30% FTA), PB (40% FTA), PC (50% FTA), PD (100% PK), PE (0% FTA) in the feed. The test feed was given at 5% of the biomass weight, twice a day at 07.00 and 17.00 WIB. The bawal fish fry used had an average size of 5.19 ± 0.71 cm and an average weight of 2.57 ± 0.08 g, with a stocking density of 15 fish/m3. The results of the study showed that the administration of fermented Azolla powder increased the growth of bawal fish fry. The use of 40% fermented Azolla microphylla flour (PB) produced the best results in terms of fish length growth at 4.85%, weight growth at 6.5%, and the highest protein content at 72.56% with the use of 30% Azolla microphylla fermentation.
