Impact of Post-Disaster Rehabilitation Activities On Farmer Economic And Social Conditions Around The Sinabung Mountain
No full textThe disaster in Karo District due to the eruption of Mount Sinabung on September 15, 2013 has claimed lives, damage to homes, agricultural land and property. This affected the economic and social conditions of affected farmers, so the government intervened to improve these conditions through a rehabilitation and reconstruction program. The purpose of this study is to compare the economic and social conditions of the community before and after the eruption of Mount Sinabung due to rehabilitation and reconstruction activities and examine community participation in recovery activities. The analytical method uses the non-parametric Wilcoxon Signed Rank Test, with two related samples namely the measurement of conditions before the disaster and after the post-disaster rehabilitation-reconstruction are not mutually free. The results show that the land owned by respondents after the disaster was reduced, but land tenure by respondents increased because they rented land elsewhere. The types and number of livestock have decreased such as buffalos and chickens, but cattle have increased due to the aid in purchasing cattle. Money capital has increased because of the provision of financial assistance from the private sector or government. The number of kiosks and sales turnover increased with the change of the area around the disaster into a tourist destination. Likewise, farm family income has increased with the new arable land in Siosar which is planted with vegetables in addition to the results of coffee on the old land that is ready to harvest. Resilience of respondent faces disaster and willingness to rise from disaster in the category of vulnerable and increasing. Work ethic in the high category increases, but in the medium category it actually decreases. The dependency of aid from the government in the high category increases, but in the low category it decreases

No full textThe aim of this research to improve the productivity of a local variety of chickpea by enriching the soil produced indigenous microorganism (IMO) and reducing the rate of nitrogen fertilizer. The experimental design used in this study was randomized complete block design with three replications. In this research, the soil was enriched with indigenous microorganism with different rates.The treatment combinations were soil with three different rates of IMO (Soil + 0, 2 and 4Tbsp of IMO) .The N fertilizer used in this study was installed in three different rates (0, 30 and 60 ppm NFR) in form of Urea in water) each rate of NFR was measured according to the weight of the soil in the pot. Morphological characters and yield component were determined in this research. The morphological characters included the height of plant, number of branches, days to 50% flowering (days), days to physiological maturity (days) and yield components were: pods number /plant, seed number/plant, seeds weight/plant (g), hundred seed weight (g) and grain yield (kg/ha). The result illustrated that the main effect of IMO gave maximum plant height, number of branches, number of pods/plant, number of seeds/plant, weight of seeds/plant, hundred seeds weight and grain yield. The combination of IMO and NFR under treatment of (Soil + 4Tbsp IMO) with application of 30 ppm NFR also gave highest value of each of morphological characters and yield components. The result of this study demonstrates that enriching soil with 4Tbsp optimize the rate of N fertilizer to 30 ppm

Contribution of Penja Pepper Production on Economic Well-Being in Cameroon
No full textImproving household well-being by intensifying agricultural production is a major concern of most developing countries. Our main objective is to quantify the contribution of Cameroon Penja pepper production on economic well-being. With the used of multiple correspondence analyses we constructed a well-being indicator using primary data collected among pepper producers and the result is estimated using ordinary least square. The results show that Penja pepper production is significantly corroborating with household economic well-being. The result is explained by industrial pepper production, while climate change, financing difficulties and availability of cultivated land are the main constraints faced by Penja pepper farmers. Decision makers should create policies to regulate the pepper market in terms of exportation of the crop. This is a wise step towards increase household economic well-being
