Analisis Kesuksesan Penerapan Sistem Informasi pada Sistem Informasi Pelayanan Terpadu (SIPT) Online (Studi pada PT Jamsostek (PERSERO))

Sistem Informasi Pelayanan Terpadu (SIPT) Online PT Jamsostek (Persero) isan implemented Information System by PT Jamsostek (Persero) to support service for memberof social security program in Indonesia. This research is to test whether system quality,information quality, and service quality positively affect on user satisfaction and to test whethersystem quality, information quality, service quality positively, task-technology fit, and usersatisfaction have positive effect on indvidual impact.. Model used in this research was DeLoneand McLean's Information System Success Model (1992), which was modified by addingconstruct of service quality, task-technology fit and eliminating construct of use andorganizational impact of the model. The research was done on employee in PT Jamsostek(Persero) branch offices in Indonesia. Data was obtained by mail survey. 519 questionnairescollected and analysed by using software Smart PLS version 2.0.. The result of test indicatedthat user satisfaction is significantly influenced by system quality, information quality, andservice quality. In addition individual impact due to system use is significantly influenced bysystem quality, information quality, service quality, task-technology fit, and user satisfaction

Pengaruh Mikroba Tanah Terhadap Pertumbuhan Dan Hasil Panen Kedelai (Glycine Max L.)*[effect of Soil Microorganism on the Growth and Yield of Soybean (Glycine Max L.)]

A study was conducted in order to know the effect of soil microorganism as biofertilizer on the growth and yield of soybean (Glycine max L.) in Malang, East Java.The purpose of the study was to get inoculants as biofertilizer to improve the production of soybean.The experiment was carried out in Bantur village, Bantur district, South Malang, East Java, by using the rice land.The strain used were five single inoculants as follows: A (Bio 20R + Bio 22R + Bio 277R), B (Bio 277R + Bio 278R + Bio 302R), C (1L + 8L + Bio 302R), D (Bio 20R + Bio 22R + Bio 277R + Bio 278R + Bio 302R + 1L + 8L), V (MVA fungi), and four mixed inoculants (AV, BV, CV, and DV). Four controls as uninoculated plant and without fertilizer (Ki), uninoculated plant and with Urea fertilizer equal to 100 kg/ha (K2), uninoculated plant and with TSP fertilizer equal to 80 kg/ha (K3), uninoculated plant and with Urea and TSP fertilizer (K4). The experiment was designed as Randomized Complete Block as 13 treatments with three replications for each treatment, and interval planted with 20 x 35 cm. The plants were harvested after 90 days. The parameters of investigation were the dry weight of canopy, roots, root nodules, seeds, 100 of seeds, number of nodules and pods with harvest productions. The results showed that single inoculants (MVA fungi) and mixed inoculants CV (1L + 8L + Bio 302R) and MVA fungi) gave better results on the production of soybean

Isolasi, Populasi Dan Karakterisasi Bakteri Pelarut Fosfat Pada Daerah Perakaran Dan Tanah Dari Bengkulu, Sumatra

The research was conducted in order to know the isolation, population and characterizations of phosphate solubilizing bacteria on the soil from rhizosphere plants from Bengkulu, Sumatra. The purpose of the study to know the population of phosphate solubilizing bacteria from rhizosphere plants, and the get pure culture. The sample wastaken from 25 sample soil from rhizosphere of plants. Isolation was done with dilution methods in standard medium Pycosvkaya, the inculation at (27-280C) after 15 days, and the population with plate count methods. The population of phosphate solubilizing bacteria was in the range of 13-101 X 105 CFU/g soil, and the highest population wasfound from the sample soil from rhizoaphere with Semangka (Citrulus lanatus) plant. Seventy five gave of pure culture. The growth characteristic of pure culture was observed by using Pycosvkaya medium. Incubation at (27-280C) after 15 days. The clear zone surround the colonies indicate that the phosphate in the medium was hydrolyzed and the formed zone from two days until eight day

Komunikasi Pendek Isolasi Populasi Dan Karakterisasi Bakteri Rhizobium Pada Tanah Asal Taman Nasional Gunung Halimun*[isolation of Population and Characterization of Rhizobium Bacteria in Soil From Gunung Halimun National Park, West Java]

The studies on the isolation of population and characterization of Rhizobium bacteria have been carried out in soil samples from Gunung Halimun National Park. West Java. Soil samples taken from rhizospheres of rasamala (Altingia exsetsa), puspa (Schima wallichii)and kianak (Castanopsis aciaunaassima).Isolation was done in YEMA (Yeast Extract Mannitol Agar) medium, and the population done with MPN (Most Probable Number) method. The growth characteristic was observed by using YEMA medium mixed respectively with Brom Thymol Blue and Congo Red as indicators.The population of Rhizobium bacteria in YEMA medium was in the range of 0.28-35 5CFU/g "' soil x 10 . The highest population of Rhizobium bacteria was found from the samples collected from soil with rasamala (Altingia excelsa) as the host plant Twent> four isolates were isolated, including nine isolates may be grouped as slow growing, while fifteen isolate
