Isolasi Dan Uji Potensi Isolat Bakteri Pelarut Fosfat Dan Bakteri Penghasil Hormon Iaa (Indole Acetic Acid) Terhadap Pertumbuhan Kedelai (Glycine Max L.) Pada Tanah Kuning
Biofertilizer is a safe alternative fertilizer instead of various chemical fertilizers for increasing plant productivity which can minimize the ecological damage. There are plant symbiotic-soil bacteria which can solubilize phosphate or produce IAA. The objectives of this research are to determine the best soil bacteria in producing IAA or solubilizing phosphate and to know their roles in promoting plant growth in unfertile soil. As many as 8 isolates of phosphate solubilizing bacteria and 5 isolates of IAA producing bacteria were found. Among those isolates, there were 2 potential isolates (P2 & P4) that were able to solubilize phosphate and 1 potential isolate (I3) that was able to produce IAA. Isolate P4 produced holozone as wide as 1.45 cm and isolate P2 was 1.3 cm. Meanwhile, isolate I3 produced the highest concentration of IAA compared to the other isolates, that was 33.3 ppm. These isolates were applicated further on unfertile soil (yellow soil) as a medium for soybean growth. Soybeans have been grown for 10 weeks to observe the effect of those potential isolates on plant growth and productivity. The result showed that application of isolate I3 was able to promote plant growth and increase plant productivity better than the other isolates as well as controls (fertile and unfertile soil). It promoted the soybean growth such as plant height was 58,8 cm; plant fresh weight was 3.5 g; plant dry weight was 1.55; pod fresh weight was 1.23; pod dry weight was 1.03; the amount of the pod was 3 and the number of the seed was 7
Isolasi Dan Uji Potensi Bakteri Tanah Pertanian Berastagi Sumatera Utara Dalam Mendegradasi Fungisida Antracol Berbahan Aktif Propineb
Isolation and potential Berastagi agricultural soil bacteria, North Sumatra in degrading propineb-based antracol fungicide has been conducted. The isolated bacteria were grown on Bushnell Hass Broth (BHB) containing 2% of propineb-based antracol fungicide with propineb as the active compound. The cultures have been grown on shaking incubator at 150 rpm for 21 days. The media BHB containing 2% of propineb-based antracol fungicide without bacteria was used as a control. The parameters observed were the growth bacterial, biosurfactant activity, biosurfactant concentration and the residues of propineb which were observed on day 0th, 7th, 14th and 21th. A total of sixteen bacterial isolates were isolated using selective media Bushnel Hass Agar (BHA) containing 2% propineb-based antracol fungicide​​. Two bacterial isolates which were CBA 02 and JBA 04 were selected for further test to determine their ability to degrade propineb. JBA 04 showed much higher ability in reducing propineb concentration up to 60.86%, while CBA 02 was only 5.59% than that of control
The Implementation of Integrated One-Stop Service at Licensing Service Agency in Order to Improve Licensing Service to Society (Case Study on Business License Service at Investment and Integrated Licensing Service Agency (IILSA) of Pasuruan City)
This study discusses about the implementation of integrated one-stop licensing services related to service of SIUP, conducted by the Investment and Integrated Licensing Service Agency (IILSA) in Pasuruan City. In general there are any issues related to License for business activities, namely: the complicated procedures, high costs and legal uncertainty. To overcome this problem the government issued Permendagri number 24 of 2006 about Guidelines for the Implementation of One Stop Services. The focus of this study discusses the implementation of an integrated one-stop service, based on the rules associated with seeing some of the following elements: (1) executing actor (2) communication (3) resources (4) bureaucratic structure (5) the target group. This research used descriptive method with qualitative research approach. Activity of data analysis in this study consisted of data reduction, display and verification of data. The result of this research can be said that the implementation is done by IILSA of Pasuruan city has been good although there are a few things that need to be improved related to the internet connection is still an obstacle in the implementation of the operational in the delivery service for SIUP and also the lack of facilities and infrastructure available
