Abstract

Study on gonad maturity of coconut crab (Birgus latro) was carried out from June 2004 to January 2005.  Crabs were collected by some gears such as trap, net and by hand. Observation was done to know sex ratio, gonad maturity and eggs diameter, while analysis was employed to estimate condition factor, gonado somatic index and fecundity.  Observation result showed that condition factor, gonad maturity and gonado somatic index varied depending on sampling month. Gonado somatic index showed a high value around November/December.  A similar result was also showed by condition factor and gonado somatic index that was high around November /December. Fecundity varied from 58.717 to 197.400. Oocyte diameter varied from 0,015 to 0,035 mm,  had one mode that is clasified to be a total spawner. Keywords :  Gonad maturity, coconut crab (Birgus latro), total spawner.   ABSTRAK Penelitian tentang kematangan gonad kepiting kelapa (Birgus latro) dilakukan sejak Juni 2004 sampai Februari 2005.  Sampel kepiting ditangkap dengan menggunakan beberapa peralatan, yaitu perangkap, jaring dan secara langsung dengan tangan. Pengamatan dilakukan terhadap jenis kelamin, kematangan gonad dan diameter telur, sedangkan analisis dilakukan untuk menentukan faktor kondisi, indeks kematangan gonad, dan fekunditas.  Hasil pengamatan menunjukkan bahwa faktor kondisi, kematangan gonad dan indeks kematangan gonad bervariasi tergantung dari bulan pengambilan contoh. Pengamatan kematangan gonad menunjukkan bahwa nilai tertinggi terdapat pada November/Desember.  Keadaan yang sama juga ditunjukkan dengan nilai faktor kondisi dan indeks kematangan gonad yang cukup tinggi pada bulan November /Desember. Fekunditas berkisar antara 58.717-197.400 butir telur. Diameter telur berkisar antara 0,015-0,035 mm,  memiliki 1 puncak sehingga dapat diklasifikasikan sebagai total spawner. Kata kunci :  Kematangan gonad, kepiting kelapa (Birgus latro), total spawner.

Abstract

This study examines the use of Dahlia tubers (Dahlia variabilis) in catfish cracers product (Clarias batrachus) as functional food.  This research was conducted in Laboratory of Livestock Technology UNTAD.  The study was conducted on September up to December 2015. Research method that used was AOAC (2009) to examine the content of inulin and proximate test, while for the organoleptic quality used (SNI 01-2346-2006) method. The research design were Completely Randomized Design (CRD) and Random Group Design (RGD). The result of the research showed that the yield generated on processing of Dahlia tubers into flour is 17.73%, the best inulin content contained is 2.14% at the variable F4. The best result of proximate test are at the variable F4 with 7.25% water content, 4.31% ash content, 0.24% crude lipid, and 1.06% crude fiber.  The organoleptic quality of catfish cracers consistenly give unreal influence (p>0.01) toward the appearance , smell , texture and taste while the texture give highly significant effect (p<0.01).
