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.

The Ministry of Agriculture through the Agricultural Quarantine Agency (2019) stated that Robusta coffee has contributed 41% of the country's foreign exchange, with an average export frequency of 102 times per month, and will continue to increase. In connection with the growth in export volume of robusta coffee, coffee farmers need additional substances for the soil in the form of nutrients to be able to meet the soil nutrient needs for coffee from planting to harvest. Organic fertilizer in liquid form is one type of fertilizer that can be an option, in addition to facilitating nutrient absorption. This study aims to determine the response of various liquid organic fertilizers at certain concentrations to the vegetative growth of robusta coffee. The content of C-organic and total Nitogen in the soil which has been given the addition of gamal liquid organic fertilizer and tofu wastewater with the addition of citronella can provide a very significant difference in the vegetative growth of robusta coffee plants at the age of 60 HSP at plant height, and 90 HSP in diameter. stem and number of leaves (strands). Based on the results of laboratory tests carried out, it was also known that the macro and micro nutrient content in the soil with the addition of poc of tofu wastewater which was given citronella had a good content compared to the control and soil conditions with the addition of gamal liquid organic fertilizer.

Penelitian ini untuk mengetahui pengaruh pemberian bokashi kotoran kambing terhadap pertumbuhan pepaya California, mengetahui pengaruh pemberian MOL nasi basi terhadap pertumbuhan pepaya California dan mengetahui interaksi pemberian bokashi kotoran kambing dengan MOL nasi basi terhadap pertumbuhan pepaya California. Penelitian dilaksanakan di Jalan Tegal Rejo, Kecamatan Palaran, Kota Samarinda. Penelitian dilaksanakan mulai Februari 2021 sampai dengan Juni 2021. Penelitian ini mengunakan Rancangan Acak Kelompok dengan analisis 3 x 4 dengan 3 kali ulangan. Faktor pertama adalah pupuk bokashi kotoran kambing yang terdiri dari 3 taraf : K0 = 0 kg/tanaman (kontrol), K1 = 6 kg/tanaman dan K2 = 12 kg/tanaman. Faktor kedua adalah MOL nasi basi yang terdiri dari 4 taraf : N0 = 0 ml/L (kontrol), N1 = 50 ml/L, N2 = 100 ml/L dan N3 = 150 ml/L. Data yang diperoleh dianalisa dan diuji lanjut dengan uji BNT 5% Hasil penelitian menunjukan pemberian pupuk bokashi kotoran kambing dengan dosis yang berbeda berpengaruh nyata terhadap tinggi tanaman 45, 60, 75, 90 HST, jumlah daun 75 dan 90 HST, diameter batang 45, 60, 75, 90 HST dengan perlakuan terbaik K1 : 6 kg/tanaman. Pemberian MOL nasi basi dengan konsentrasi yang berbeda tidak berpengaruh nyata terhadap semua parameter pengamatan. Interaksi kedua perlakuan yaitu bokashi kotoran kambing dan mol nasi basi tidak memberikan pengaruh nyata semua parameter pengamatan.   Kata kunci : Pupuk Organik, Tanaman Hortikultura, Unsur Hara

This study aims to determine the nutrient levels of Liquid Organic Fertilizer (POC) Wastewater and Lemongrass Wastewater and soil nutrient status sub-optimal land after incubation for 21 days. Sub-optimal land is land that naturally has low productivity, therefore it is necessary to add nutrients in both organic and inorganic fertilizers to change nutrient status in the soil. Organic fertilizer in liquid form is one type of fertilizer that can facilitate the absorption of nutrients. Tofu wastewater has an unpleasant odor, one of the efforts that will be made to reduce the odor is by adding fragrant lemongrass in making liquid organic fertilizer. Based on the results of the study note that the total macro nutrient levels (N + P2O5 + K2O) Liquid Organic Fertilizer Wastewater and Lemongrass Wastewater is 0.17% with a degree of acidity 4.39. Suboptimal soil nutrient status after incubation for 21 days with different concentration treatments namely 10%, 30% and 50% addition of Liquid Organic Fertilizer tofu waste water and lemongrass experience changes in potassium nutrient status at concentrations of 0%, 10 %, 30% and 50%, while the phosphorus changes at concentrations of 30% and 50%, but not nitrogen.
