The Effect of Light and Nutrients on the Development of Fruit of Peanut (Arachis Hypogaea (L.). Merr.)

This study aims to determine the effect of light and nutrients to the fruit development of peanut (Arachis hypogaea). The study was conducted in the greenhouse of Biology Education Departement of Nusantara PGRI Kediri University by a completely randomized design with two factors, namely: nutrients, consists of six levels (complete nutrient, without K, Ca, P, Mg and without nutrients) and the light consists of two levels (dark and light condition). The nutrients provided is a Hoagland solution (1938). The parameters measured were the length of fruits, that were measured at the harvesting time. Data were analyzed by F test factorial, and if there is a significant, then continued by least significant difference (LSD) test, using the Stats program 6.2 version. The peanut fruit development is inhibited by light but its stimulated by the interaction between the dark and nutrients. The fruit is grown in the dark with a complete nutrient is the longest both fruits and seeds

Pertumbuhan dan Mortalitas Ikan Endemik Opudi (Telmatherina prognatha Kottelat, 1991) di Danau Matano, Sulawesi Selatan

Lake Matano is an ancient lake that has a high endemicity. Opudi fish (Telmatherina prognatha) is an endemic fish that is vulnerable to extinction and needs to be preserved. The threat of invasive species and habitat degradation can cause a decrease in opudi fish populations. This study aimed to examine the growth parameters associated with growth coefficients and mortality in Lake Matano so that population can be sustainable. The study was conducted at Lake Matano from March 2018 to February 2019. Samples of fish were caught using a net bag measuring 30 m long, 2 m wide with a mesh size of 0.5 inches. Analysis of fish growth was based on total length-frequency data. These data were analyzed using the FISAT II software. The sizes of male and female opudi fish obtained ranged from 30-70 mm. Growth patterns of von Bertalanffy butina in male fish are male Lt = 76.50 [1-e-0.46 (t + 0.47)] and female fish Lt = 74.05 [1-e-0.51 (t + 0.52)]. The total mortality value of male fish was higher (Z = 1.65) compared to female fish (Z = 1.50), the natural mortality value of male opudi fish was lower (M = 0.84) compared to that of female fish (M = 0.91).   Keywords: endemic fish, growth, mortality, Telmatherina prognath

REPRODUCTIVE BIOLOGY OF Moolgarda sp. IN SEGARA ANAKAN LAGOON CILACAP DISTRICT, CENTRAL JAVA

Segara Anakan lagoon was water located in the estuary between Ciamis regency and Cilacap regency. The purpose of this research is to observe sex ratio, the maturity level of gonad, and the gonad maturity index of Moolgarda sp. Sampling was conducted for three months, from March to May 2017. The method used is a simple random sampling method. The results of research that the sex ratio of Moolgarda sp. male is higher than female. The gonad maturity level of Moolgarda sp. was obtained from levels I, II, III, and IV. The Gonad Maturity Index value Moolgarda sp. males ranged from 0.0022% - 1.3041% while GMI Moolgarda sp. female 0.0424% - 5.5827% with a fecundity of Moolgarda sp. from 7356 - 131350 eggs

Morphological and Histological Structures of Gonad of Coconut Crab (Birgus Latro)

The study was aimed to investigate the secondary morphological and histological structures of gonad of coconut crab (Birgus latro). Morphologically, male and female gonads were described based on size, surface condition, colour and ocupied stage in abdomen. Histologically, male gonad was described based on appearance of spermatocyte, spematid and spermatophore using PAS-Hematoksilin method, while female gonad was described on oocyte development, nucleus condition, and deposit of oocyte using Hematoksilin-Eosin methods. Morphologically, testes are smooths, white-brownish, and occupied about 9-40% abdoment, while ovarium surface are smooth-granule, whitish, grey-dark, red, and occupied about 25-80% abdoment. Histologically, the testes showed spermatocyte, spermatid, and spermatozoa in spermatophore, while the ovarium showed oocyte at premature-mature conditions

Aquatic environmental characteristic of Singkil Swamp Wildlife Reserve in Aceh Singkil Regency

 Singkil Swamp Wildlife Reserve is a peat swamp ecosystem located in Aceh Singkil Regency, Aceh Province. Peat swamp ecosystem has an important function in protecting and balancing water systems, carbon stocks and biodiversity conservation. However, information on the characteristics of the waters of this ecosystem is still not widely known, especially in the area of utilization that is influenced by community activities. This study aims to determine the aquatic environmental characteristics of the Singkil Swamp Wildlife Reserve utilization area covering the physical and chemical parameters of the water and the relationship among those parameters. Sampling was carried out through field observations both in-situ and ex-situ at 5 stations for 3 months (April-June 2021). Observations were made on water quality parameters namely temperature, transparency, depth, current, colour, salinity, water smell, pH, DO, TDS, TSS, conductivity, phosphate and nitrate. Analysis of the data was conducted, namely correlation analysis, PCA (Principal Component Analysis) and CA (Cluster Analysis). The water color was black and the pH was acidic, that is a characteristic of the swamp waters. The results of the measurement of water quality parameters indicate that TDS (13-44 mg/l), TSS (9-236 mg/l), total phosphate (0.01-2.14 mg/l), and nitrate (0.5-25.7 mg/l) were suitable for freshwater aquaculture to support fishery reserve. Based on the clustering of those stations, 5 observation stations were grouped into two different groups, namely cluster 1 with the number of observation stations of 2 stations (Stations 1 and 2) and cluster 2 with the number of observation stations of 3 stations (3, 4 and 5). The parameter values of total phosphate, pH, DO, and nitrate in cluster 1 tend were higher than in cluster 2.Keywords:Peat swampFreshwaterWater qualit
