Opis:
This research aims to determine the method of adding potassium diformate to commercial feed to increase survival and growth in gourami juvenile. The method used in this research is an experimental method using a Completely Randomized Design (CRD), consists of four treatments and four replications. The treatments used are (A) Without giving Potassium diformate (control), (B) giving potassium diformate by 0.3%, (C) giving potassium diformate by 0.5% and (D) giving potassium diformate by 0.8%. The test fish used was 300 giant gourami with a length of 4-6 cm. The containers used in this research were aquariums with a size of 40 × 30 × 40 cm3 that reared in 16 aquariums. The density of giant gourami fingerlings during the research was 10 fish per aquarium. The rearing period was 40 days. The feed given was 3% of body mass. Water quality parameters (temperature, pH and dissolved oxygen) were observed every 10 days. Other parameters are the daily growth rate, feed efficiency, the survival rate and the acidity of intestinal and stomach which were observed every 10 days. The results showed that the addition of potassium diformate by 0.3% gives the best results of daily growth rate of 1.31%, feeding efficiency of 37.18%, survival rate of 100% and decreased acidity in the intestine and stomach which helps in the process of protein absorption.

In the present investigation the seeds of Pigeon pea (Cajanus cajan (L.) Millsp) were treated with different doses of gamma radiation (05KR, 10KR, 15KR, 20KR, 25KR, 30KR, 35KR, 40KR, 45KR, and 50KR) and concentration of Ethyl Methane Sulphonate (05mM, 10mM, 15mM, 20mM, 25mM, 30mM, 35mM, 40mM, 45mM, and 50mM) for studying seed germination, seedling height, (shoot and root), seedling injury, seedling vigour index, and seedling survival of plants at 30th day. The seed germination percentage was decreased with increased in the concentration/doses when compared to control. The LD50 (Lethal dose) value was determined based upon the seed germination percentage. The 50 percentage of seed germination and reduction was observed in 20KR of gamma rays and 25mM of EMS and it is considered as LD50 value for both the treatments. The decrease in seed germination was more prominent with gamma rays than that of EMS treatments. The seedling parameters of gamma rays and EMS treated seedlings were progressively decreased with increase dose/concentration in all mutagenic treatments when compared to control. The maximum seedling parameters were observed in 05KR of gamma rays and 05mM of EMS. Minimum seedling parameters were observed in 50mM of EMS and 50KR of gamma rays respectively.

Opis:
From the hands of Olmec, Maya including Inca from whom Corn evolved to all parts of the globe, maize has provided Man with Nutritive, Medical, Pharmaceutical, Industrial, Domestic, Economic including Research values. Corn stands at the center of Mankind, providing Humanity with raw materials for further survival and development. As the need for corn doubles, and as science further widens knowledge on the use/utilization of the crop, creating more avenue and approaches where corn grains, leaves, silk, stem, root and other parts of the plant can be transformed into countless products, then the need to devote more hectares of land to Corn production becomes imperative. Corn has been shown to have the potential to be used in combating global food insecurity, as an indicator-crop for soil fertility assessment and as a commercial cash crop for income generation. Production of Corn has reduce poverty rate and raise standard of living of farmers, especially in the poor/developing countries.

Opis:
The natural occurrence of the shrimp (Penaeus monodon Fabricius, 1798) and seagrass (Cymodocea rotundata Asch. & Schweinf.) is found in the area of Indian Ocean, Indonesia, for central Pacific. Vibriosis can cause death in larvae, juvenile and adult shrimp almost close to 100%. Antibacterial substances from secondary metabolites are produced by plants and animals to reduce the use of synthetic antibiotics. The purpose of this research was to determine the ability of secondary metabolites contained in the bacterial extract of the association of sea grass Cymodocea rotundata (isolate code BA.1) to treat vibriosis in tiger shrimp (Penaeus monodon). This research was conducted at the Laboratory of Integrated Biotechnology and Laboratory of Aquaculture, Fisheries and Marine Sciences Faculty, Universitas Padjadajaran, and at the Brackish and Southern Ocean Aquaculture Development Center Pangandaran, from June to September 2018. The research method used was experimental, with completely randomized design (CRD) consisting of five treatments with three replications including; control treatment (concentration of 0 mg·L–1), 150 mg.L–1, 300 mg·L–1, 450 mg·L–1 and 600 mg·L–1. Observations made include clinical symptoms (morphology, behavior) and survival rate. Clinical symptoms of infected tiger shrimp during the in vivo test were red spots on the abdomen and necrosis of some leg and tail segments. The behavior of tiger shrimp mostly shows less responsive movements to fish-feed on the first day, and showing responsive and active behavior on the fifth day. In vivo test results for 14 days showed that the highest survival rate of 51.67% was in case of the addition of antibacterial extracts of BA.1 with a concentration of 300 mg·L–1.
