Abstract

Beta Fish Predation Power and Guppies Against the Third Instar Larvae of Mosquitos as a Vector Control Efforts in Dengue Fever         Dengue Hemorrhagic Fever (DHF) disease was a disease caused by dengue virus infection remains a public health problem in Indonesia. The disease attacks all age groups every years. Effort to eradication DHF done by fulfill the predator of fish like cupang and guppy. The study to determined the difference of predation potential between betta and guppy toward the 3rd instar of larvae Aedes aegypti. This study was experimental with comparative study and one shoot chase study design. The population was larvae of Aedes aegypti mosquito 3rd instar with betta and guppy as many as 5. Every treatment used the larvae as many as 25. The treatment observe in 1, 2 , 4 and 6 hours the data analyze used the independent samples test. The results of independent samples test got the p value 0.000, proves there were the significantly difference of predation potential of betta and guppy toward the 3rd instar III of Larvae Aedes aegypti mosquito. Suggested to the society can used the predator fish to eradication the DHF disease. Keywords: The potential of predator fish Cupang (Betta sp.), Guppy (Poecilia reticulata), 3rd instar of larvae, Aedes aegypti. ABSTRAK        Demam Berdarah Dengue (DBD) merupakan penyakit yang disebabkan oleh virus dan ditularkan oleh nyamuk Aedes aegypti yang masih menjadi masalah kesehatan masyarakat di Indonesia. Penyakit ini menyerang semua kelompok umur dan muncul setiap tahun. Pengendalian DBD dilakukan dengan memanfaatkan ikan seperti ikan cupang dan guppy. Penelitian ini bertujuan untuk mengetahui perbedaan  daya predasi  ikan cupang (Betta sp.) dan ikan guppy (Poecilia reticulata) terhadap larva instar III nyamuk Aedes aegypti. Jenis penelitian ini adalah  eksperimental bersifat komparatif dengan desain one shoot chase study. Subyek penelitian adalah larva nyamuk Aedes aegypti instar III, ikan cupang dan guppy masing-masing sebanyak 5 ekor. Setiap waktu pengamatan  menggunakan larva instar III sebanyak 25 ekor dan diulang sebanyak 5 kali. Pengamatan dilakukan selama 1, 2, 4 dan 6 jam. Analisis data menggunakan independent samples test. Hasil uji Independent Samples Test didapatkan nilai p value 0.000, membuktikan adanya perbedaan yang bermakna antara daya predator ikan cupang (Betta sp.) dengan ikan guppy (Poecilia reticulata) terhadap larva instar III nyamuk Aedes aegypti. Daya predator paling baik adalah  ikan cupang. Disarankan kepada masyarakat untuk memanfaatkan ikan predator dalam upaya mengendalikan penyakit Demam Berdarah.Kata Kunci: daya predator ikan cupang (Betta sp.), ikan guppy (Poecilia reticulata), larva instar III nyamuk Aedes aegypti.

Abstract

Optimation of Polyethylene Glycol (PEG) 6000 Treatment on Isolation of Agarose Seaweeds of Glacilaria sp         Isolation of agarose from seaweeds (Glacilaria sp) had been done in acid, base, and neutral condition by using polyethylene glycol (PEG) method. Glacilaria sp, Seaweeds that used in this research was cultured by farmer in Muara Gembong, Bekasi. It used PEG with concentration 10%, 15%, 20%, 25%, & 30%. The scope of this research ware determination of seaweeds, seaweeds water content, isolation of agarose from seaweeds, and quality test of agarose. Parameter test of agarose quality include  the strength of gel, the content of sulfat, measurement of galactose content and its proksimat. The high yield was 61,27% r  in PEG 30%. The best quality of agarose was resulted in PEG 20% because of the highest strength of gel was 379,04 g/cm2.The lowest sulfat concentration was 1,33% and galactose was 17,39%.Key words: polyethylene glycol, PEG 6000, agarose, seaweeds, glacilaria sp ABSTRAK         Isolasi agarosa dari rumput laut Glacilaria sp telah dilakukan dalam suasana asam, basa dan netral dengan metode polyethylene glikol (PEG). Rumput lauat yang digunakan adalah Gracilaria sp yang dibudidayakan oleh petani di Muara Gembong, Bekasi dengan perlakuan konsentrasi PEG 10%, 15%, 20%, 25% dan 30%. Ruang lingkup penelitian ini meliputi uji determinasi rumput laut, penetapan kadar air rumput laut, isolasi agarosa dari rumput laut, serta uji kualitas agarosa. Parameter pengujian kualitas agarosa terdiri dari kekuatan gel, kandungan sulfat, dan pengukuran kandungan galaktosa serta proksimatnya. Isolasi agarosa perlakuan konsentrasi polyethylene Glikol (PEG) 6000 pada rumput laut Glacilaria sp diperoleh rendemen paling tinggi terdapat pada perlakuan PEG 30% yaitu sebesar 61,27%. Akan tetapi untuk kualitas agarosa yang paling baik terdapat pada perlakuan konsentrasi PEG 20% karena diperoleh kekuatan gel paling tinggi sebesar 379,04 g/cm2. Kadar sulfat yang paling rendah sebesar 1,33% dan kadar galaktosa sebesar 17,39%.Kata Kunci: polyethylene glikol, PEG 6000, agarosa, rumput laut, glacilaria sp
