Pengaruh Ablasi Mata terhadap Kecepatan Kematangan Gonad Kepiting Bakau (Sylla Serrata) Betina

Kepiting bakau (Scylla serrata) merupakan jenis golongan Crustaceae yang mengandung protein hewani yang cukup tinggi dan memiliki nilai ekonomis yang tinggi. Ablasi mata merupakan salah satu cara untuk menghilangkan hambatan perkembangan telur (gonad) pada kepiting bakau. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) non factorial dengan 4 perlakuan dan 3 ulangan. Adapun perlakuan dalam penelitian ini adalah perlakuan A (ablasi satu pasang mata), perlakuan B (ablasi mata kiri), C (ablasi mata kanan), D (tanpa ablasi). Hasil penelitian menunjukkan bahwa kecepatan kematangan gonad tertinggi pada perlakuan C (ablasi mata kanan) yaitu pertumbuhan gonad mencapai 21,53% dan terendah terjadi D (tanpa ablasi) pertumbuhan gonad hanya 14,8%. Analisa statistik dengan uji F menunjukan bahwa ablasi mata berpengaruh terhadap kecepatan kematangan gonad kepiting bakau. Pertambahan bobot tertinggi terdapat pada perlakuan C (ablasi mata kanan) yaitu sebesar 2,67 gr kemudian disusul oleh D (tanpa ablasi) sebesar 1,89 gr dan terakhir pada B (ablasi mata kiri) dengan nilai rata-rata sebesar 0,77 gr. Tingkat kelangsungan hidup terbaik terdapat pada perlakuan D (tanpa ablasi) yaitu 100%, perlakuan B (ablasi mata kiri) 77,77%, perlakuan C (ablasi mata kanan) 66,66% dan kelansungan hidup terendah terjadi pada perlakuan A (ablasi satu pasang mata) 0%. Rata-rata kualitas air selama penelitian adalah suhu 27 0C dan Ph 7,65.Mangrove crab (Scylla serrata) have been classifying in Crustaceae clas that containing high animal protein and high economic value. Ablation of the eye is an solution to eliminate the egg development (gonads) barriers in the mangrove crab. The research design used a completely randomized design (CRD) non- factorial with 4 treatments and 3 replications. Treatment in this study were the treatment of A (ablation of the pairs of eyes), treatment B (left eye ablation), treatment C (right eye ablation), D (without ablation). The results showed that the highest rate of gonadal maturation was in treatment C (right eye ablation) where gonadal development growth reached 21.53 %, whereas the lowest was in treatment D (without ablation) where gonadal development growth was only 14.8 %. Statistical analysis by F test showed that ablation of the eye was affected the mud crab gonadal maturity. The Weight gain was found highest in the treatment C (right eye ablation) that reached 2.67 g and followed by treatment D (without ablation) 1.89 grams and the last in the treatment B (left eye ablation) with was an average value 0.77 grams. The higest survival rate was found in treatment D (without ablation) 100 %, treatment B (left eye ablation) 77.77 %, treatment C (right eye ablation) 66.66 % and the lowest survival rate was occurred in treatment A (ablation of the pairs of eyes) 0 %. The avarge values of water quality during the study showed that the temperature was reched 27 0C and pH was 7, 65

Student Satisfaction Analysis of Siater Using End User Computing Statisfaction (EUCS)

The purpose of this research is to know the extent to which students levels of satisfaction level of Strata-1 University of Bandar Lampung on the Sistem Informasi Akademik dan Administrasi Terpadu (SIATer) and any indicators that need to be improved in order to increase student satisfaction against SIATer. This type of research using a quantitative approach. The respondents determined using techniques research of Stratified Random Sampling with certain criteria. As for sample determination technique using tables Stephen Isaac & Willian B. Michael. From the results of the study showed that university students Bandar Lampung has yet fully satisfied against SIATer. Based on the method of End User Computing Statisfaction (EUCS), note that the indicators should be improved in order to increase student satisfaction is an indicator of formats, ease of use, and from the side of timeliness

Pengaruh Lama Waktu Paparan Medan Listrik terhadap Pertumbuhan Benih Ikan Patin (Pangasius SP)

Penelitian ini bertujuan untuk mengetahui pengaruh waktu paparan medan listrik pada media air bersalinitas 3 ppt. Penelitian dilaksanakan pada bulan Oktober hingga November 2014 di Laboratorium Hatchery dan Teknologi Program Studi Budidaya Perairan Fakultas Pertanian Universitas Malikussaleh Aceh Utara. Perlakuan yang diberikan yaitu: perlakuan A (Kontrol), B (1 menit), C (3 menit) dan D (5 menit). Pengambilan data dilakukan setiap 7 hari sekali. Rancangan yang digunakan berupa Rancangan Acak Lengkap (RAL) dengan 4 perlakuan 3 ulangan dan dilanjutkan dengan Uji Beda Nyata jika terdapat perbedaan. Parameter yang diamati berupa pertambahan bobot, pertambahan panjang, kelangsungan hidup, dan efisiensi pakan. Hasil penelitian menunjukkan bahwa ikan patin yang diberi perlakuan 1 menit, 3 menit dan 5 menit mampu merespon medan listrik. Pemberian medan listrik 10 volt selama 3 menit menghasilkan nilai pertambahan bobot, pertambahan panjang, dan efisiensi pakan yang paling baik, yaitu masing-masing sebesar 0,65 gram/ekor, 0,29 cm/ekor, dan 91,09 %. Kelangsungan hidup ikan uji selama penelitian berkisar antara 83,33 % - 100 %, dimana yang terbaik diperoleh pada pemberian paparan listrik selama 3 menit. Selama penelitian ini suhu air yang diperoleh berkisar antara 26,60C sampai 29,30C, dan pH berkisar antara 6,8 sampai 8,5. This study was aimed to know the expoture time effect of electric voltage in saline water 3 ppt. The study was carried out on October until November 2014 at Laboratorium of Hetchery, Major of Aquaculture Malikussaleh University. Several treatments given in this study were A (Control), B (1 Minute), C (3 Minute), D (5 Minute). Data were sampled every 7 day. Reseach design used was completely ran domized design with four treadments and three replications, then it was continued by using LSD test.
