Abstract

White shrimp (Litopenaeus vannamei) culture has grown rapidly in Indonesia since  early 2000s. White shrimp have stronger resistance to WSSDV attacks, and are euryhaline. In it’s natural habitat, this shrimp was found in waters with a range of 0.5-40 ppt salinity. White shrimp grow optimally at 15-25 ppt salinity, even still suitable at 5 ppt salinity. This capability provides the opportunities to culture these commodities in inland water. White shrimp need inorganic elements or minerals for their living processes. Calcium is one of the main needs of shrimp that is closely related to the development and maintenance of skeletal systems and plays a role in some physiological processes of the body.The requirement for calcium in shrimp is increasing when it is cultivated in fresh water.This Internship aims to find out the technique of adding calcium carbonate (CaCO3) in feed, used for the white shrimp culture in fresh water. In this field practice, the addition of calcium carbonate in a level of 2% refers to the requirement of white shrimp for optimal growth. This was based on the calcium requirements of shrimp in the amount of 1-2%. The method was repelleting, by grinding feed and calcium using mortar and pestle, then filtered to get the smoothest part. Then mix calcium with 10 mL of water and mix it with pellets evenly. Then the mixture is air dried and mashed again and weighed according to the required dose of feed. The addition of calcium in the feed affects the growth of shrimp, because calcium is one of the most important anorganic mineral for the growth and development of exoskeleton, regulates blood clotting, heart rate, kidneys, nerves, the activity of several enzymes, and cell function

Abstract

Botia fish (Chrombotia macracanthus), known as the clown loach, is a species of freshwater ornamental fish from the Cobitidae family whose distribution is limited to the islands of Borneo and Sumatra. The limitations of Botia fish distribution make it necessary to increase the maturity of the gonadal Botia fish to increase the breeding of these fish. The results of the evaluation of the effect of gonadotropin hormone on fish Botia carried out for four days and on the first female parent produced as many as 15,898 eggs with FR (Fertilization Rate) of 57.5% and HR (Hatching Rate) of 60.5%. The second Botia parent produces 10,872 eggs with FR (Fertilization Rate) of 96.5% and HR (Hatching Rate) of 13.7%. HCG serves to homogenize the size of the egg and accelerate gonadal maturity. Ovaprim serves to accelerate the ovulation process and stimulate spawning.

Abstract

The concept of planting, especially in urban areas, is very suitable for implementing a hydroponic system, given the increasingly narrow condition of agricultural land. Plant nutrition using AB Mix Solution is considered to be expensive and also contains chemicals. The combination of AB Mix and POC rice washing water is expected to support the growth and yield of Pakcoy plants to the maximum. The selection of horticultural plants (Pakcoy) is due to the nutritional value and benefits of the vegetable plants themselves. The research was conducted in Experimental Field 1 and Lab. Agrotechnology Agronomy Unit, Faculty of Agriculture, by applying a Completely Randomized Design located under the lettuce nursery in a plastic house. The treatments include 100% AB Mix + 0% POC, 80% AB Mix + 20% POC, 60% AB Mix + 40% POC, 40% AB Mix + 60% POC, and 20% AB Mix + 80% POC. . The parameters to be observed consisted of plant height (cm), leaf length (cm), number of leaves (strands), and leaf width (cm), average wet weight of plants, and dry weight of shoots and roots (gr) calculated by drying yields using an oven at a temperature of 80 0C for 2 x 24 hours. The results showed that there was no significant difference between the combination of AB Mix and POC for all variables with P3 treatment showing higher parameter values than others. However, for the wet weight measurement, P0 showed a higher yield, due to the high water content in the plant

Abstract

Abstract. Viewed from the perspective of law enforcement, with the rarity of filing a claim for compensation or a request to merge a claim for compensation, it requires careful research because after all the core of law enforcement is upholding rights and carrying out obligations. The purpose of this study is to show that the use of the right to claim compensation or a request for compensation is very rare. Qualitative research uses a descriptive approach to collect data systematically, factually, and quickly according to the description when the research was conducted. The results of this study indicate that the method of claiming compensation can be done by merging a claim for compensation in a criminal case, through unlawful acts and through a request for restitution.
