No full textABSTRACT Information about white shrimp stocks (Penaeus merguensis de Man) is still very minimal, especially in the waters of the Kakap River Kubu Raya Regency, West Kalimantan. This study aims to determine the stock of white shrimp caught in the Kakap River. The method used in sampling is swept area by determining the area of the trawl catching area and taking white shrimp samples 10% of the catch. Research in the field was carried out for 2 months, namely in May-June 2019. Based on the results of research that has been done, the area of trawl fishing gear swept area reached 0,016 km2. White shrimp caught during the study were 530, of which there were 208 male and 322 females. The long distribution of white shrimp carapace observed during the study ranged from 12,64-41,72 mm, and weighed 1,16-11,45 grams. The length and weight relationship of male, female and combined white shrimp is negative allometric. White shrimp caught in the Kakap River based on the K value obtained 1,2 results per year with an L∞ value of 21,48 mm male and a K value of 1,2 per year with an L∞ value of 30 mm female, while the combined obtained a K value of 1,1 per year with L∞ 32,2 mm.

STRAWBERRY RESPONSE ON LIQUID INORGANIC NUTRITION AND ORGANIC LIQUID FERTILIZER IN AGGREGATE CULTURE
No full textThis study aimed to get the best combination of inorganic nutrients and organic liquid fertilizer of coconut fiber as a nutrient solution for aggregate culture on growth and yield of strawberries. The study was conducted at from February 14th to April 25th 2019. This study used a Completely Randomized Design (CRD). The treatment given as combination of inorganic nutrients and organic liquid fertilizer was five levels of: k0 (100% organic liquid fertilizer), k1 (75% inorganic nutrients), k2 (75% inorganic nutrients with organic liquid fertilizer TDS 1.300 ppm), k3 (75% inorganic nutrients with organic liquid fertilizer TDS 1.800 ppm), and k4(100% inorganic nutrients). Variables observed such as root volume, plant height, leaf number, number of stolons, number of flowers, number of fruits, fruit and dry weight of strawberry plants. The results showed that application a combination of imorganic nutrients and organic liquid fertilizer did not increased the growth and yield of strawberries. Providing 75% of inorganic nutrition increased the growth and yield the same as given 100% of inorganic nutrition. Keywords: inorganic nutrition, organic liquid fertilizer, strawberries
