Abstract

Percobaan dilakukan untuk mendeterminasi pengaruh berbagai kombinasi pakan alami terhadap penampilan reproduksi induk udang windu (Penaeus monodon Fab.) local (dari perairan Siwa) dan membandingkan potensi reproduksi induk udang windu local dengan yang berasal dari Aceh.  Pakan percobaan terdiri dari 50% cumi-cumi dan 50% cacing laut (D1), 30% cumi-cumi, 30% cacing laut dan 40% kerang (D2) , 30% cumi-cumi, 30% cacing laut dan 40% rajungan (D3) serta kombinasi antara cumi-cumi, cacing laut, kerang dan rajungan masing-masing 25% (D4). Potensi reproduksi dievaluasi berdasarkan fekunditas dan daya tetas telur, sedangkan kualitas larva dievaluasi berdasarkan tingkat kelangsungan hidup dan pertumbuhan dari stadia nauplii-1 ke stadia zoea-1. Hasil penelitian mengindikasikan bahwa  fekunditas, daya tetas dan pertumbuhan larva yang berasal dari induk yang diberi pakan kombinasi antara cumi-cumi (50%) dan cacing laut (50%) adalah yang paling tinggi, diikuti oleh cumi-cumi (30%), cacing laut (30%) dan kerang (40%).  Tingkat kelangsungan hidup larva tidak dipengaruhi oleh pakan yang pakan percobaan.  Potensi reproduksi dan kualitas larva induk udang windu local dan yang berasal dari Aceh yang diberi pakan yang sama yaitu 50% cumi-cumi dan 50% cacing laut nampak identik.Kata kunci: Induk udang windu, kombinasi pakan, penampilan reproduksi. Experiments were conducted to determined the effect of various natural diet combination on reproductive performance of local prawn (Penaeus monodon Fab.) broodstock (from Siwa waters) and  to comparing  the potential reproduction of local and Aceh prawn broodstock.  Experimental diet  consisted of 50% squid and 50% sea worm (D1), 30% squid, 30% sea worm and 40% mussels (D2), 30% squid, 30% sea worm and 40% swimming crab (D3), and combination between squid,  sea worm, mussels and swimming crab 25% for each other  (D4). The potential reproduction  were evaluated based on the fecundity and  hatchability,  and larval quality were evaluated based on survival rate and growth from nauplii-1 to zoea-1.  The research indicated that fecundity, hatchability and growth of larvae from broodstock fed combination between squid (50%) and sea worm (50%) diet was higher and following by broodstock fed combination between  squid (30%), sea worm. (30%) and mussels (40%).   Survival rate of larvae not affected by the test diets.  Identical  reproduction potential and larvae quality of local and Aceh prawn broodstock with the same food combination (50%) squid and sea worm  (50%) was showed. Key words: Black tiger broodstock,diet combination, reproductive performance.

Abstract

Dalam model efek komunikasi massa, pers diasumsikan memiliki pengaruh positif juga negatif. Melalui pemberitaan yang berimbang, pers dapat membantu masyarakat  menjelaskan situasi yang tengah bergolak. Di sisi lain, melalui pemberitaan yang tidak akurat, pers dapat menambah eskalasi konflik yang tengah terjadi. Sementara itu, dalam kondisi keterpurukan bangsa saat ini, pers Indonesia ditengarai menyikapinya dengan menampilkan kecenderungan pemberitaan mengarah pada isu-isu politik yang hangat, kontroversial, dan penuh sensasi. Peristiwa yang langsung berkaitan dengan realitas masyarkat, seperti kemiskinan, pengangguran, degradasi moral, dan lain-lain, malah luput dari perhatian pers. Gejala ini memperlihatkan pers Indonesia belum sepenuhnya berpihak pada masyrakat. Padahal, fungsi pers paling utama justru melayani publik. Pers Indonesia, di tengah euforia kebebasan pers saat ini, karenanya perlu menengok kembali undang-undang, kode etik, atau pun standar profesional yang menempatkan masyarakat sebagai titik tolak pengabdiannya – baik dari segi jurnalistik, isi media, narasumber, maupun kontrol sosial.

Abstract

The use of mass media (especially television) for political campaign has started since four decades ago. US Presidential Election (1950) became an example of how advertising and news became sites of political campaign. In Indonesia, political campaign through advertising began in 1999 General Election. In effect, this phenomenon gave birth to PR Politic: the use of PR consultant to manage political campaign and political leader’s publicity. In local election of DKI Jakarta, Fortune PR and Hotline dominated campaign consultant activities for government candidates. The use of advertising and news in political campaign essentially follows marketingand promotion principles as well. Both are trying to sell products to a particular consumer by applying some strategies. Success will be measured from popularity of a particular candidate, a significant change of voter’s decision, and candidate image.
