Abstract

This research intended to evaluate the area suitability of  Scylla spp at Likupang II Village, North Minahasa. The research was done descriptively by observing water quality, area availability. SWOT analysis was used to determine the development strategy.   Data were collected by interview, observation and questionnaire.  Research result showed that the potential of Likupang II Village was suitable for Scylla spp culture.  SWOT analysis showed internal factors affected the development of Scylla spp culture.  The strength were location, water quality, government support; the weakness were seed availability, opportunity, government policy and treating were season and safety.   Keywords : Scylla spp, SWOT analysis, , Likupang II, area suitability

Abstract

The research intends to determine the optimal concentration of honey addition in sperm dilution on sperm motility, fertilization and eggs hatchability of Nile Tolapia (Oreochromis niloticus). Experimental design used was a Complete Randomized Design (CRD) with three times repetition of four treatments. The concentration of honey addition used for treatment are A (0 ml of honey in 100 ml of physiological NaCl), B (0.60 ml of honey in 99.40 ml of physiological NaCl), C (0.65 ml of honey in 99.35 ml of physiological NaCl), D (0.70 ml of honey in 99.30 ml of physiological NaCl). Parent used consisted of five female parent and five male parent with 250 – 500 mg weight. Sperm dilution containers used was 12 plastic cups and the container fertilization and hatching eggs container used was 12 brass plates.  Spermatozoa motility observation performed immediately after dilution process. Fertilization observation was performed after 12 hours of fertilization process, and Egg Hatchability observation was performed after 60 hours of fertilization.  The observation results showed that the addition of honey in sperm dilution contributed significant effect on spermatozoa motility, fertilization and eggs hatchability of Nile Tolapia (Oreochromis niloticus). This observation showed that the addition of 0.70 ml of honey in a sperm dilution was the best treatment seen from the average percentage of spermatozoa motility (73,33 %), fertilization (80,00%) and eggs hatchability (77,33 %.)

Abstract

Tujuan dari penelitian yaitu untuk mengetahui struktur komunitas mangrove di Desa Lamanggo dan Desa Tope, untuk mengetahui kelimpahan kepiting bakau di hutan mangrove, dan untuk mengetahui hubungan antara kerapatan mangrove dengan kepadatan kepiting.Penelitian dilakukan dengan menggunakan metode line transek kuadran dengan menentukan lima lokasi titik pengamatan pengambilan sampel, dan untuk mengetahui kondisi mangrove maka dilakukan perhitungan kerapatan jenis, frekuensi jenis, penutupan jenis, dominasi, indeks nilai penting dan keanekaragaman serta analisis kelimpahan kepiting bakau yang berhubungan dengan kerapatan mangrove dengan rumus Y = a + b X.. Dari hasil penelitian yang dilakukan, diketahui bahwa jenis mangrove yang memiliki nilai kerapatan tertinggi yaitu Rhizophora apiculata, dan untuk nilai frekuensi tertinggi juga yaitu jenis Rhizophora apiculata, sedangkan untuk nilai dominasi tertinggi dimiliki oleh jenis Sonneratia alba.Berdasarkan uji korelasi antara kerapatan pohon mangrove (X) terhadap kepadatan kepiting (Y) sebagaimana terlihat diperoleh r sebesar = 0,814 dengan Fhitung sebesar 1.94 < Ftabel 10.12. Hal ini berarti tidak terdapat hubungan yang signifikan antara kerapatan  mangrove dengan kepadatan kepiting bakau. Selanjutnya untuk melihat besarnya kontribusi kerapatan mangrove terhadap kepadatan kepiting dicari melalui koefisien determinasi R² = 0.66 yang berarti variabel kerapatan pohon mangrove tidak memberikan kontribusi terhadap kepadatan kepiting. Karena jika setiap penambahan variabel X, maka variabel Y akan berkurang sebesar 67.54937 - 0.110 X.
