PEMBERIAN Lactobacillus sp. PADA PAKAN UNTUK MENINGKATKAN PERTUMBUHAN UDANG VANAME (Litopenaeus vannamei) DI TAMBAK INTENSIF
Get PDFWhite shrimp (Litopenaeus vannamei) is one of the economically important shrimp that has several advantages including tolerance of water conditions, can grow quickly, and thick flesh. One of the problems in white shrimp cultivation is the slow growth of white shrimp due to inappropriate feed management. The addition of grampositive bacteria to the feed is scientifically believed to increase the growth of white shrimp. Among the grampositive bacteria that are commonly added to white shrimp aquaculture activities, namely Lactobacillus sp., this bacterium has many advantages for the survival of white shrimp in aquaculture activities. The addition of Lactobacillus sp. can increase the digestibility of feed due to simplification of complex proteins into simpler proteins so that the feed is easily absorbed by white shrimp. The results obtained from the administration of Lactobacillus sp. bacteria in the feed were getting very good growth results, the growth results from the lowest to the highest were A1 = 23.8 grams/head, A2=28.1 gram/head, A3=24.3 gram/head, A4=22.1 gram/head, A5=22.4 gram/head, A6=18.8 gram/head.Udang vaname (Litopenaeus vannamei) adalah salah satu udang ekonomis penting yang memiliki beberapa kelebihan diantaranya adalah toleransi kondisi air, dapat tumbuh dengan cepat, dan daging yang tebal. Salah satu permasalahan dalam budidaya udang vaname yaitu pertumbuhan udang vaname yang lambat akibat pengelolaan pakan yang tidak sesuai. Penambahan bakteri gram positif pada pakan secara ilmiah diyakini dapat meningkatkan pertumbuhan udang vaname. Di antara bakteri gram positif yang biasa ditambahkan pada kegiatan budidaya udang vaname yaitu bakteri Lactobacillus sp., bakteri ini memiliki banyak keuntungan bagi kelangsungan hidup udang vaname pada kegiatan budidaya. Penambahan bakteri Lactobacillus sp. dapat meningkatkan kecernaan pakan akibat penyederhanaan protein kompleks menjadi protein yang lebih sederhana sehingga pakan mudah diserap oleh udang vaname. Hasil yang diperoleh dari pemberian bakteri Lactobacillus sp., pada pakan yaitu mendapatkan hasil pertumbuhan yang sngat baik, hasil pertumbuhan dari yang terendah sampai yang tertinggi yaitu A1= 23,8 gram/ekor, A2=28,1 gram/ekor, A3=24,3 gram/ekor, A4=22,1 gram/ekor, A5=22,4 gram/ekor, A6=18,8 gram/ekor.

Tingkat Kesukaan Hama Plutella xylostella dan Belalang (Locusta migratoria) Terhadap Tanaman Kubis Bunga (Brassica oleracea var. botrytis L.) Dataran Rendah yang diberi Kompos Azolla dan Pupuk NPK
Get PDFThis study aims to study (1) the level of Plutella pest preference, and (2) the level of grasshopper (Locusta sp) pest preference for lowland cabbage (Brassica oleracea var. Botrytis L.) on various combinations of Azolla compost and NPK fertilizer. The research was carried out in the Horticulture practice land of Lampung Polytechnic in July 2018 to September 2018. The study was arranged in factorial in a randomized block design (RBD) with 9 treatment combinations and 3 replications, so that there were 27 experimental units. The combination of treatment is as follows: The first factor is Azolla bulk compost (A) which consists of 3 levels of dosis namely: a1 = 2 tons Ha-1, a2 = 4 tons Ha-1, and a3 = 6 tons Ha-1. The second factor is the dosage of NPK fertilizer (B) which consists of 3 dosage levels, namely b1 = 0 kg ha-1, b2 = 100 kg ha-1 and b3 =200 kg ha-1. Observations were made on the intensity of Plutella xylostella and Grasshopper (Locusta sp) attacks. at the age of 17 days (1) and age 24 days (2). The data was tested by F test and the difference in treatment was followed by the smallest real difference test (LSD) level of 5%. The results obtained from the F test on the variable intensity of Plutella xylostella attack (1) were observed: azolla and NPK compost doses affected the intensity of xylostella plutella attack at the age of 17 days, while at 24 days the dose of azolla and NPK compost had no effect on pest attack this. So until the age of 17 days the administration of azolla and NPK compost still causes pests. Xylostella plutella likes flower cabbage leaves, while at the age of 24 days the flower of cabbage leaves has not been favored by these pests. For locust pests (Locusta sp), azolla dose and azolla interaction with NPK fertilizer significantly affected the attack of locust pests (Locusta sp) on cabbage flowers aged 17 days, while at the age of 24 days, only NPK doses affected the locust attack on flower cabbage plants. Thus, the adequacy of nitrogen nutrient supply causes high Plutella xylostella pest preference until the plant age of 17 days and decreases in plant age of 24 days, while for locust pest (Locusta sp) the level of preference continues until the plant age of 24 days.
