Abstract

This article tries to describe the M. Abdullah Darrāz’s toughts on i’jāz al-Qur`ān as basic of reading-cum-understanding on the Qur`ān. Initially, the discussion of i’jāz al-Qur`ān started from debate among the scholars about theological doctrines on the Qur`ān such as al-mu’āraḍah, at-taḥaddī, tark al-mu’āraḍah, and al-’ajz. But, Darrāz was able to discussed the discourse of i’jāz into domain of Qur`anic interpretation, and also Qur`anic reception in his work: an-Nabā` al-’Aẓīm: Naẓarāt Jadīdah fī al-Qur`ān. Through his work, Darrāz was able to formulated the principles of reading-cum-understanding on the Qur`ān are sourced from its i’jāz—which I term it with qirā`ah i’jāziyyah ’an al-Qur`ān—such as principle of coherence, intertextuality and stylistics of the Qur`ān.

Abstract

This paper discusses the current status of tilapia aquaculture production, historical development based on the production growth, technological advances in genetic improvement and culture system, trade and product development, strategies, and policies in maintaining and improving national production. All data and information used in this manuscript were collected from available publications relating to the past and present status of tilapia cultivation in the country. Nowadays, Indonesia is the second-largest tilapia producer in the world with the contribution of about 25.89% to tilapia global production. In Indonesia, tilapia is the largest production among other cultured species. The annual growth production of tilapia is inccread 11.61% from 2011 to 2018. West Java Provinceis the largest tilapia producer followed by West Sumatra, South Sumatra, and Central Java. In the last six years, most of tilapia production comes from pond culture followed by floating cages, net cages, paddy fields, and pen culture. The success of tilapia culture is much influenced by technological improve in grow-out and genetic improvement of the local varieties. A side of that, trading and global market oriented are also established with various acceptable products. Tilapia aquaculture in Indonesia shows the succsess story of freshwater aquaculture program from nothing before 1990 to be something at present time. To maintain and increase the future production of tilapia, it needs strategies and policies in production and trade. The tilapia program maybe used as a role model for another economic imprortant freshwater species in Indonesia.

Abstract

ABSTRACTSnakehead Channa striata is a local specific fish species and has high economic value. Until now the production of snakehead still reelies on the catch of nature because cultivation of snakehead is still underdeveloped. The main constraint in snakehead fish farming is high mortality on snakehead juvenile rearing phase. This study was conducted to determine the best stocking density on snakehead juvenile rearing to achieve optimal production. The treatments used in this study were stocking density of 1 juvenile/L, 2 juveniles/L, and 3 juveniles/L. Snakehead juveniles with a length of 3.41 ± 0.39 cm and weight 0.28 ± 0.07 g, were reared for 42 days in the aquarium sized 40×40×40 cm with a volume of 40 L. Fishes were fed by bloodworms in ad libitum method. The result showed that the treatments did not affect the survival, growth and the ratio of RNA/DNA of snakehead juvenile. Survival of juvenile snakehead ranged 92.5‒94.58% (P>0.05). The result of water quality measurement showed that it was on optimum condition to supporting snakehead growth at 3 juveniles/L stocking density. Furthermore, recirculation can be use to maintenance water quality for optimum condition. Thus, the rearing of snakehead fish juvenile in the recirculation system can use a stocking density of 3 juveniles/L, and the recirculation system could maintain the water quality in good condition. Keywords: growth, recirculation system, snakehead fish, stocking density, survival rate  ABSTRAK Ikan gabus Channa striata merupakan ikan spesifik lokal dan mempunyai nilai ekonomis tinggi. Sampai saat ini produksi ikan gabus masih mengandalkan tangkapan dari alam karena kegiatan budidaya ikan gabus masih belum banyak berkembang. Kendala utama dalam budidaya ikan gabus adalah tingginya mortalitas pada fase pemeliharaan benih. Penelitian ini dilakukan untuk menentukan padat tebar terbaik dalam upaya memperoleh pertumbuhan dan sintasan terbaik. Perlakuan yang digunakan dalam penelitian ini adalah padat tebar 1 ekor/L, 2 ekor/L, dan 3 ekor/L. Benih ikan gabus dengan panjang rata-rata 3,41± 0,39 cm dan bobot rata-rata 0,28 ± 0,07 g dipelihara selama 42 hari di dalam akuarium berukuran 40×40×40 cm dengan volume air 40 L. Benih ikan gabus diberikan pakan berupa cacing sutera secara ad libitum. Hasil penelitian menunjukkan bahwa penggunaan padat penebaran yang berbeda tidak memengaruhi sintasan dan pertumbuhan dan rasio RNA/DNA benih ikan gabus (P>0,05). Sintasan benih ikan gabus pada akhir pemeliharaan berkisar antara 92,5‒94,58%. Hasil pengukuran terhadap kualitas air pada kepadatan 3 ekor/L masih dalam kondisi optimum untuk mendukung pertumbuhan benih ikan gabus sehingga sistem resirkulasi yang digunakan dapat mempertahankan kualitas air dengan baik. Hasil penelitian menunjukkan pemeliharaan benih ikan gabus pada sistem resirkulasi sebaiknya menggunakan padat tebar 3 ekor/L dan sistem resirkulasi dapat mempertahankan kualitas air dalam kondisi baik. Kata kunci: ikan gabus, pertumbuhan, padat tebar, sintasan, sistem resirkulasi.
