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.
For some Indonesian people, housing is one of the secondary needs, so that in choosing the right housingmust be in accordance with the wishes of consumers. With the existence of PT. Maxima Jaya Perkasa, which waspioneered since 2012, in which the data on housing sales in the company has increased rapidly each year. Then datamining analysis can be done using the K-means Clustering method. K-means Clustering is a method of clustering nonhierarchicaldata which seeks to partition existing data into two or more groups. This method partitioned the data intogroups so that the data with the same characteristics were entered into the same group and the data with differentcharacteristics were grouped into other groups. This study uses data such as salary income, age, status, house pricesand mortgage payments. The results of this study were conducted twice using 12 training data training data and 100training data plus 1 as test data and obtained an accuracy value of 83% and error of 17%.
Indonesia is an archipelago with a vast landscape. Equal access to education has been an important issue in improving the quality of education to support human resource provision. This study is a narrative review study based on reflections during conducting multi-year research from 2015 to 2020 funded by MOEC. During the research period, authors arranged socialization, training, mentoring, and measuring the impact of mobile learning implementation in rural and remote areas, especially in eastern Indonesia. The results of this study indicate that there is good potential for mobile learning to support equitable access to education. Governments need to consider several essential aspects so mobile learning can work well. The aspects are the readiness of infrastructure and the readiness of technology acceptance by educational decision-makers and principals. The results of this study, as a whole, can be used as a basis for developing various educational policies in the disadvantaged region.
Demam Berdarah Dengue (DBD) merupakan penyakit yang disebabkan oleh gigitan nyamuk Aedes yang terinfeksi salah satu dari empat tipe virus dengue dengan manifestasi klinis demam, nyeri otot dan atau nyeri sendi yang di sertai leukopenia, ruam, trombositpenia dan diathesis hemoragik. Ada 5 kriteria untuk menentukan seorang pasien dikategorikan positif atau negatif DB, yaitu variabel Usia pasien, Jenis kelamin pasien, peningkatan hemoglobin (Hb), peningkatan trombosit dan peningkatan hematrokit (Ht) berdasarkan kriteria tersebut maka akan dilakukan klasifikasi data pasien positif dan negatif DBD dengan metode K-Nearest Neighbor berbasis web. metode K-Nearest Neighbor (KNN) memiliki kelebihan menghasilkan nilai error yang kecil. Algoritma KNN menggunakan klasifikasi ketetanggaan sebagai nilai prediksi dari sampel uji yang baru. Dekat atau jauhnya nilai tetangga biasanya dihitung berdasarkan jarak euclidean. Berdasarkan dari hasil penelitian dan pembahasan yang dilakukan, klasifikasi diagnose penyakit demam berdarah ini menggunakan algoritma KNN dengan variabel usia, jenis kelamin, hemoglobin, trombosit, hematrokit.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
