Faktor Nyamuk Culex dan Babi dalam Penyebaran Virus Japanese Encephalitis (J.e.) di Pontianak dan Solo

A sero-epidemiological study was conducted in Solo (Central Java) and Pontianak (West Kaliman­tan) to compare the role of culex mosquitoes and pigs in transmitting the Japanese Encephalitis (J.E.) virus in the community. Data were obtained from 898 children at 6—7 y.o. using C.F. test, while light traps and mosquito larval collection gained from 235 houses in endemic and silent areas, and from 416 pigs collected from farmers, using H.I. test. The high infection rate against J.E. among children in Pontianak (44.4%) compared with in Solo (6.8%) was correlated with the higher infection rate (100.0%) and higher geometric mean of antibody titer (> 80) among pigs population rather than with the Culex density which was found high in both cities. Cx. gelidus was found only in Pontianak , but its role in transmission was not studied yet

Penyakit Japanese Encephalitis (J.e.) Pada Anak-anak Di Dua Rumah Sakit Di Jakarta Dalam Tahun 1981

From April 1981 to March 1982, 118 suspected clinically Japanese Encephalitis cases among chil­dren were admitted to two hospitals in Jakarta. Serological confirmation with H.I. and IAHA tests showed a 4-time increase against JE antigen in 25.4% cases and against Dengue antigen in 17% cases. Both diseases afflicted mainly children in the age group of 0-5 years. More severe symptoms and sequalae were found among JE cases then among Dengue Encephalitic Syndrome (DES) cases. The differential diagnosis for DES can be easily made if rash is present. The diagnosis of JE with WHO criteria were for 75% confirmed by the serological test. Out of 144 spinal fluid collected, four had CPE in LLCMK2 and two in PMK cell lines, further passages failed to demonstrate more CPE

Larvasidasi Masal dalam Rangka Penanggulangan D.h.f. di Sidoarjo, Jawa Timur, 1983 - 1984

A serological based study was conducted in Sidoardjo, East Jawa, to evaluate the effecti­veness of mass larvaciding of Aedes mosquitoes. Seven hundreds and fourty four children (7 y.o.) from endemic areas and another 742 children from non-endemic DHF areas were randomly selected to measure the difference of transmission rate at one month interval, before and after mass larvaciding was excecuted. Abate SG at 1 ppm were used for mass larvaciding in an endemic area only with total coverage 93.4%. Thirthy seven percent of reduction in transmission rate was achieved by mass larvaciding compared with 110% of increase in transmission occuring in the control areas. A level of 2,9% transmission rate in a population with a 100% infection rate will still result in DHF occurance although in a very small number

Hubungan Perilaku Petani dengan Sistem Pelaksanaan Teknoloogi pada Usahatani Padi Sawah di Desa Sri Agung Kecamatan Batang Asam Kabupaten Tanjung Jabung Barat

Penelitian ini menggunakan metode sampling simple random dan pemilihan daerah penelitian secara purposive. Sampel terdiri dari 60 orang yang terbagi menjadi 20 kelompok tani yaitu pada kelas kemampuan lanjut dan pemula. Analisis data perilaku petani dan sistem pelaksanaan teknologi pada USAhatani padi sawah dilakukan secara deskriptif sedangkan analisis hubungan perilaku petani dengan sistem pelaksanaan teknologi pada USAhatani padi sawah menggunakan uji Chi Square dengankontingensi 2 x 2. Hasil penelitian menunjukkan bahwa 65 persen petani memiliki perilaku positif dan 35 persen berperilaku negatif 66,67 persen sistem pelaksanaan teknologi pada USAhatani padi sawah tergolong tinggi dan perilaku petani berhubungan nyatadengan sistem pelaksanaan teknologi yang diamati melalui pengetahuan, sikap dan keterampilan petani dalam berusahatani padi sawah. Perbedaan perilaku petani menyebabkan perbedaan sistem pelaksanaan teknologi pada USAhatani padi sawah didaerah penelitian. Perilaku petani dengan sistem pelaksanaan teknologi memiliki hubungan kuat. Keeratan hubungan sebesar 0,650, artinya 65 persen tinggi rendahnya sistem pelaksanaan teknologi padi sawah disebabkan oleh positif negatifnya perilaku petani terhadap USAhatani padi sawah di daerah penelitian. Terdapat hubungan yang nyata antara perilaku petani dengan sistem pelaksanaan teknologi USAhatani sawah didaerah penelitian. Hal ini berarti semakin positif perilaku petani (pengetahuan, sikap dan keterampilan) maka akan menunjang sistem pelaksanaan teknologi pada USAhatani padi sawa

Pemanfaatan Limbah Sargassum Polycystum Dari Industri Farmasi Sebagai Pupuk Cair Serta Pengaruhnya Terhadap Sifat Kimia Tanah Ultisol Dan Pertumbuhan Tanaman Sawi

The aim of this research to know the effect of seaweed liquid fertilizer (Sargassum polycystum) made ​​from waste materials on the growth and production of mustard (Brassica juncea L.) on ultisol. This research was held in gauze house, Chemistry/Soil Fertility Laboratory and Research Laboratory, Agricultural Faculty, University of North Sumatra, Medan in June-September 2012. The sample of soil to used is ultisol. The research used a Completely Randomized Design (CRD) Non Factorial with nine treatments and three replications that are twenty-seven experimental units. Treatment consists of P0 (Control), Pa2 (EM-4 20 cc with liquid seaweed fertilizer every 2 days), Pa3 (EM-4 20 cc with liquid seaweed fertilizer every 3 days), Pa4 (EM-4 20 cc with liquid seaweed fertilizer every 4 days), Pa5 (EM-4 20 cc with liquid seaweed fertilizer every 5 days), Pb2 (EM-4 40 cc with liquid seaweed fertilizer every 2 days), Pb3 (EM-4 40 cc with liquid seaweed fertilizer every 3 days), Pb4 (EM-4 40 cc with liquid seaweed fertilizer every 4 days), Pb5 (EM-4 40 cc with liquid seaweed fertilizer every 5 days). The result of experiments showed that seaweed liquid fertilizer different is not real to pH of soil, C-organic of soil, N soil, K-exchange, C/N of soil. But, real different to the P-available of soil, fresh weight of plants, fresh weight of root, dry weight of plant and dry weight of root
