Abstract

Fusarium oxysporum Schlecht. f.sp. cepae (Hanz.) Synd. et Hans. is a fungus that causes Fusarium wilt in shallots, which causes damage to tubers and reduces yields by more than 50%. This disease is difficult to control, because it can form spores that can survive in the soil for a long time, and are saprophytic on the remains of other plants. This study was conducted to determine the effect of the application of 5 kinds of Actinomycetes isolates (SW13, SW5, BYM1, BYM4, and SIO 5), with 3 kinds of concentrations (5 ml, 10 ml, and 15 ml/plant) on the Mentes variety shallots. Fusarium oxysporum. The results showed that the application of the isolate code SIO5 to the Mentes variety of shallots gave the best effect in suppressing the attack of Fusarium oxysporum by 52.2%. In addition, the suspension of SIO5 isolate also had a positive effect on plant height of 41.5 cm, number of tillers of 8.89, and tuber weight of 42.84 grams. While the type of concentration did not have a good effect on the incidence of disease, plant height, and the number of tillers and tuber weight.

Abstract

Zebra fish (Danio rerio) is a laboratory animal that can be used for a wide field of research, testing, and education. Laboratories that wish to use Zebra Fish must have their own Zebra Fish rearing facility. The next step is to breed parental Zebra Fish from external sources until filial 1 (F1) is obtained in the facility which is then used later. This research is descriptive experimental, which describes the practical experience of providing maintenance, breeding, and rearing facilities for embryos and larvae. Quarantine specific facilities, number of tanks, water pH conditions, breeding methods, facility cleaning routines, and special larval feeds need to be considered for the success of early stage rearing facilities. This study showed that the embryo safety rate ranged from 38.2% to 88.9%. Meanwhile, for larvae up to the age of 21 dpf it ranged from 1.5%-9.1%, which indicated that the rearing conditions were still suboptimal, especially larval rearing. Facility procurement and maintenance costs are divided into mandatory and optional costs depending on the needs, location and time of the maintenance facility. Laboratories can independently design maintenance facilities that are effective to meet research needs and are cost efficient.

Abstract

Gulamah fish (Johnius trachycephalus) is one type of fish that is widely consumed by the community. Prolonged use of Gulamah fish can have an impact on population decline caused by fishing activities. The purpose of this study was to determine the relationship between length and weight and condition factors of Gulamah fish in the waters of the Barumun River, Labuhanbatu Regency, North Sumatra Province. Sampling points were determined based on information from local fishermen. The Gulamah fish were taken using a net, with a net length of 20 m and a width of 8 m. Sampling was carried out four times for three months. The Gulamah fish that have been caught are then taken to the Ecology Laboratory, Labuhanbatu University, for measuring length, weighing, and separating fish by sex and so on. The number of samples during this study caught 36 fish, with a total length of Gulamah fish of 15.7 cm to 19.7 cm respectively, where the total length of the dominant fish caught averaged 18.16 cm. Meanwhile, the weight of Gulamah fish ranges from 70 grams to 113 grams, with an average fish weight of 95.08 grams. To analyze the relationship between length and weight, the Linear Allometric Model (MAL) was used, by calculating the constants a and b through length and weight measurements. While the condition factor is calculated using a metric system based on the relationship between the length and weight of the sample fish. The results showed that the relationship between the length and weight of Gulamah fish was negative allometric, which means that the length growth of the fish was faster than the weight growth. Then the condition factor states that the Barumun River supports the growth of Gulamah fish.
