Abstract

Penelitian ini bertujuan untuk mengetahui lama perendaman larutan belimbing wuluh terhadap daya tetas telur ikan nila (Tilapia niloticus).  Penelitian ini dilaksanakan pada bulan Juni  sampai  Agustus 2017, yang dimulai dari tahap persiapan sampai telur menetas menjadi larva. Bertempat di Balai Benih Ikan (BBI) Limbung. Penelitian lama perendaman larutan buah belimbing dengan dosis 4000 ppm yang telah dilakukan memiliki presentase daya tetas tertinggi pada perlakuan dengan lama perendaman 10 menit yaitu 93,33%.  Di peroleh hasil rata-rata tidak berbeda nyata terhadap pada tingkat kepercayaan 95 %. Hasil pengukuran parameter kualitas air dari setiap perlakuan masih dalam kondisi layak dalam mendukung perkembangan telur hingga menjadi larva.`

Abstract

Mangarabombang is one of the locations of seaweed cultivation in Takalar and Punaga is one of village in Mangarabombang who has waters location are very supportive of local government programs to increase national production of seaweed. To Increase of seaweed is based on the government's target in Takalar So, this reaseach aims to determine effect of production levels and income levels, analysis factors  that influence the risk level of production and income as well as farmer's behavior in the face of the risk of seaweed production. The method of this reseach are random sampling of respondents with income data analysis, R/C Ratio and correlation of production and income. After processing data, showed that respondents increase seaweed production in 2014 to 2016 has significant change by followed a decrease levels income during 2016. Because of seasons and pricing from government uncertain about the unit price of seaweed in the market. In addition, the correlation data analysis showed that a strong correlation between production of seaweed and income of seaweed farming to continue in future. So much needed attention by government to make strategic policy for the increase production of seaweed and income of farmer to make sustainable seaweed better.

Abstract

Penelitian ini  bertujuan untuk Mengetahui pertumbuhan dan sintasan udang vaname (Litopenaeus vannamei) yang dipelihara menggunakan air baku dari hasil reserkulasi. Metode pengambilan sampel dalam penelitian ini dilakukandengan cara acak untuk menjaga agar tidak ada organisme yang terlalu kecil atau besar yang terambil pada saat sampling atau dalam hal ini metode yang digunakan adalah metode eksperimental yakni menguji hasil penelitian dengan ragam uji ANOVA. Hasil penelitian ini menunjukkan bahwa penggunaan kepadatan yang berbeda (1500 ekor/wadah) menyebabkanPertumbuhan mutlak, Laju pertumbuhan, dan Sintasan pada udang vaname (Litopenaeus vannamei)   meningkat. Hal inidisebabkan karena rendahnya kepadatan diperlakuan A (1500 ekor) dibandingkan perlakuan B (2000 ekor) dan perlakuan C (2500 ekor), menyebabkan tidak terjadi persaingan ruang gerak dan tidak terjadi persaingan makanan sehingga dapat memacu pertumbuhan dan sintasan udang vannamei (Litopenaeus vannamei). Pada penelitian ini disarankan, jika untukmenambah kepadatannya diharuskan menggunakan tambahan aerasi dan kincir untuk menyuplay oksigen kewadah budidaya.

Abstract

This study aims to determine the state of socio-ecological adaptation of coastal communities to the development of seaweed cultivation, and the dynamics of technostructure of coastal communities in the development of seaweed farming in Sub Lamalaka, District Bantaeng. The usefulness of this research is as information for the government to educate coastal communities in environmental preservation seaweed farming so that those resources can be used sustainably. This research was conducted in March and April 2010 in the village of Lamalaka, District Bantaeng, Bantaeng. This location was chosen intentionally (purposive) in consideration that the area is an area of development of the cultivation of seaweed (E. Cottonii) at the same seaweed production areas in South Sulawesi. The method used is the snowball sampling method with the number of informants as many as 23 people. The results showed that the adaptation of the socio-ecology of coastal communities in Sub Lamalaka occurs through the relationship of social interaction between the members of coastal communities which are then adapted to the conditions of suitability to the development of seaweed farming sustainable and in the form of the dynamics of techno structures that are in a transitional phase between the use of irrational becomes rational technology.

Abstract

The use of probiotics as an attempt to improve the cultivation environment and suppress the disease proved to help overcome some of the problems in shrimp farming. This study aims to determine the exact concentration of probiotics in shrimp maintenance Vanannamei and see the effects on water quality, growth, survival, and shrimp production Vannammei. Research carried out on a laboratory scale by using 12 aquariums measuring 30 x 25 cm with a volume of 25 liters each aquarium filled sized shrimp with stocking density 20 birds. Probiotics mixed premises of feed and given 4 times a day with a concentration corresponding treatments, A = 3 PPM, B = 4 PPM, C = 5 PPM and D controls that are set in a completely randomized design (CRD) with 4 treatments and 3 replications. During maintenance of shrimp fed as much as 5% of the total biomass with a frequency of 4 times/day, the results of research addressing that administration of probiotics with different concentrations significantly affected the growth and survival of Shrimp Vannamae although not significantly affect water quality.
