This research aims to investigate the effects of phosphate and lime fertilizer on the growth and production of soybean plants in a former wetland. It was carried at the Experimental Field of the Agriculture Faculty, Samudra University Langsa, at a height of 3 meters above sea level (MASL) and a soil pH of 5.5. The results showed that phosphate fertilizer had a significant effect on plant height at the age of 30 DAP, the number of pods per polybag, the number of filled pods, the weight of dry seeds per polybag, and the weight of 100 dry seeds; however, it had no significant effect on plant height at the age 10 and 20 DAP, as well as on the number of productive branches. The most effective type of phosphate fertilizer found in this research was P3 (TSP). The most effective type of lime fertilizer found in this study was K2 (Dolomite). The combination of phosphate and lime fertilizer found to have a significant effect on the number of pods per polybag and the number of filled pods. The best combination of phosphate and lime fertilizer was P3K2 (TSP + Dolomite) giving the best results.
The aim of this research was to determine important parameters based on farmers’ perceptions and the selection of the best alternative varieties for the development of upland rice in East Aceh. Data collected includes secondary data and primary data. Primary data collection is done by using questionnaire data in gathering information on farmers’ perceptions. Whereas the alternative selection combines elements of farmers’ perceptions and field observations of several varieties. The analytical method was carried out using observations in the field and processing data descriptively. The varieties used in the field study were Inpago 8, Inpago 9, Inpago 10, Inpago 11 and Situ Patenggang. The results of the study address important parameters in the cultivation of upland rice based on the results of the questionnaire with farmers are the age of fast harvesting plants and the average production with a very important category, then the weight of 1000 seeds in grams and the potential yield with important categories, then the productive tillers of each stem, the amount grain of each panicle (seeds) and tall plants in the Medium category. The choice of the best alternative varieties in East Aceh Regency based on the results of farmers’ perceptions and field studies were found in Inpago 9 varieties.
The aim of these activities was to provide input/recommendations to policymakers about the issues and problems of agricultural development from the study of technology adoption on integrated crop management (ICM) of rice. The event was held from March - November 2015 in four districts namely Pidie, Aceh Utara, Aceh Barat, and Aceh Barat Daya. The activities implemented through field studies with respondents are farmers who received the SLICM program (purposive sampling). Each district was selected one district and each district will be selected two villages. In-depth interview respondents as much as 10-20 farmers per village. Respondents were selected randomly from members of rice SLICM. Data collected consists of primary data and secondary data and processed by descriptive analysis. The results showed that the level of technology adoption on integrated crop management (ICM) of rice in Pidie, Aceh Utara, Aceh Barat, and Aceh Barat Daya districts is not influenced by the characteristics of the respondent, such as; age, education, and experience of farmers in cropping rice. Technology adoption on integrated crop management (ICM) of rice is still limited to the use of the technology components of new varieties and seed labeled. The various components of the basic technology and the integrated crop management selection of paddy rice, which have not adopted by respondents include intermittent irrigation, organic fertilizer utilization, weeding with grok. While legowo cropping system is still limited. The adoption rate on integrated crop management (ICM) of rice is influenced by several factors, among others: the implemented technology is easy, uncomplicated. The technology is also cheap but in accordance with the conditions of society and new technologies can provide more benefit to them (increased yield).
Cabenge River is part of the WalanaeCenranae River area in Soppeng Regency. Annually, the area around the Cabenge River gets the most losses from floods, both in terms of facilities and infrastructures. This study aims to map the areas prone to flood and flood risk, based on the field that gets the most significant impact. This study uses a Geographic Information System (GIS) as a tool and ArcGis Software in determining the level of vulnerability and risk of flooding at the study site. This type of research is a combination of mapping (topographic results) and map analysis. The variables used are DEM (Digital Elevation Model) data and flood volume. The data processing technique used is the GIS-based inundation model approach using inundation height (H) based on a comparison between the volume of water (V) in inundated areas and the volume of water (Q) of flood sources. The results showed that Lilirilau District was in the high hazard class with an area of 100 km2 and had the biggest impact, while in Liliriaja District, the area that was in a high hazard class was 34 km2 and Ganra District was 21 km2.
