Determinants of Rural Household Income in Jiangxi, China Fu Gonghua; Ge Zhijun
International Journal of Agriculture System VOLUME 2 ISSUE 1, JUNE 2014
Publisher : Hasanuddin University

Both rural poverty and the huge urban-rural gap are serious problems in China. It needs to pay more attention to the rural society, the farmer, and the agriculture. This paper focused on the determinants of rural household’s income, and attempts to find out the factors which heavily impact on their income. This study showed that agricultural incomes only shares 22% of the household income averagely, while non-agricultural income takes another 78% among the sampled rural households. The labor wage income accounted for 71% of household income. The Gini coefficient of the household agricultural income per capita was 45.57%, and that of household non-agricultural income per capita was 37.79%, and both of them are higher than the Gini coefficient of household income per capita (28.91%). This was due to the household growing more crops (more agricultural income) than others who earned less income from non-agricultural sectors. The variance of the total household income per capita was smaller than that of both agricultural and non-agricultural income per capita. The study also find out that the Main Income Earner (MIE) worked inside the county, MIE’s education attainment, MIE’s non-agricultural skill attainment, the skill source from school education, job searching information from advertisement and Consumer-Producer ratio (CP ratio) were the main determinants which impact on household net income per capita significantly. In order to increase farmer households’ income and to alleviate the rural poverty, it is necessary to help farmers to attain more education, to give farmers useful offfarm skill training, and to supply more recruitment information service. Besides, it also needs to encourage those farmers in enhancing their ability to go to urban areas to find some jobs, including skill-training.

Extracting Apis dorsata Binghamii Honey using Incision Technique Rosmarlinasiah Rosmarlinasiah; Sitti Marwah; Meisanti Meisanti

Publisher : Hasanuddin University

At the time of the flowering season arrives, honey bee colonies will actively fill the nest with honey, pollen and puppies. Along with the honey gatherers are also actively seeking to take the honey bee hive. Honeycomb (Apis dorsata Binghami) which has a hanging nest in trees was often taken by humans in an unproductive ways causing many young bees and hive contents besides honey, often wasted for the next harvest. The purpose of this study was to determine the slicing method honeycomb Apis dorsata Binghami in nature, which can speed up the next process in honey harvesting cycle. The sample consisted of eight observations of bee hive of Apis dorsata Binghami with four treatments and two replicates. Treatment P1 was slicing across the honeycomb, whereas nP2 treatment was the slicing/take part contains the honey hive, and treatment P3 used slicing whole beehive and later taped the sliced nest. P4 treatment had the honey extracted from the honey productive parts and then taped back the ex- slices from the middle of the nest. The results showed that the fastest time of bee colonies Apis dorsata Binghami back to the original nest is P4 treatment for it only took 0.000439 days while P2 took 0.000590 days. On the other hand P1 and P3 treatments took more than 80 days. Extracting just the honey from its nest will accelerate the bee colony reoccupation of their nest, compared with the whole slicing of the beehive. The faster the bee colony occupied the nest will result in quicker repair activities of the hive. The honey will be filled much faster for the next harvest revisits.

Influence of Sowing Depth and Shade on Emergence and Seedling Growth of Centrosema pubescens Muhammad Rusdy; Rinaldi Sjahril

Depth of sowing and shade levels were two ecological factors affecting early establishment of a plant. The effects of sowing depths of seeds and shade on seedling emergence, morphological traits and seedling biomass of Centrosema pubescens were examined. The seeds were sown at the depth of 2, 4, 6 and 8 cm and shaded at levels of 0 (full sunlight) and 50%. Analysis of variance showed a significant effect (P<0.05) of sowing depth on seedling performances. Sowing at the depth of 2 cm produced the highest percentage of seedling emergence, the shortest days to emergence, the biggest seedling diameter and thegreatest seedling biomass. Shade significantly (P<0.05) increased seedling height and shootroot dry weight ratio. The findings indicate that for improved growth and dry matter yield, Centrosema pubescens seeds should be sown at a depth of 2 cm.

The Effect Stubble Cutting Height on the Vegetative and Reproductive Phase of Rice Ratoon in a Tidal Swamp Evriani Mareza; Zainal Ridho Djafar; Rujito Agus Suwignyo; Andi Wijaya

Rice ratoon technology has a great potential to be developped in a tidal swamp because it can resolve various obstacles such as limited of production factor and labor, the time of planting which is depends on the season. The objective of this paper is to analyse the effect of the stubble cutting height after harvesting of first crop on the vegetative and reproductive phase of ratoon rice. The rice was planted in a tidal swamp using a direct seedling system. A randomized block design with five replicates was used. The treatment was the stubble cutting height ranged from 10, 20, 30, 40 and 50 cm from the surface of the soil. The results showed that the height of stubble cutting has significant effect on the vegetative and reproductive phases of rice ratoon. The plant height, number of tillers and number of productive tillers of ratoon was lower than first crop. The flowering of rice ratoon was faster than the first crop. Stubble cutting up to 50 cm from the surface of the soil increases plant height, number of tillers and number of productive tillers and accelerate flowering of rice ratoon. It can be known the impact of the height of stubble cutting to the vegetative and reproductive phase on rice ratoon. Future studies on effect of the height of stubble cutting for rice yield prodcution should be focussed after the ripening phase.

Structural Elucidation of Secondary Metabolites in Sponge (Callyspongia pseudoreticulata) with N-Hexane Extract M. Nurdin; Hanapi Usman; Ambo Ala; Baharuddin Baharuddin

Sponge is one of the marine species that has a high bioactivity and contains secondary metabobolite compound which can be used as antibiotic and medicine. Terpenoid compound derivatives have been successfully isolated from sponge Callyspongia pseudoretilulata by a method in which the n-hexane extract weighing 11.28 g was fractionated using vacuum column chromatography with a non-polar eluent, n-hexane. The polarity of this eluent was improved by ethyl acetic resulting in fairly polar eluent, methanol. A total of 27 fractions were obtained and one of the compounds from n-hexane extract was structurally elucidated by NMR spectroscopy and two dimensions of homonuclear and heteronuclear (1H, 13C, DEPT, H-H COSY, HMQC, and HMBC). The identified compound was a hydrocarbon (1-ethyl cyclo hex cosana-1-amin) that indicated LC50 of 60.58 against A. salina and has a great potential as antitumor or anticancer.

A Path Analysis of Sustaining Small Scale Fishing Industry in Indonesia Dedy Putra Wahyudi; Eko Sri Wiyono; Budy Wiryawan; Iin Solihin

Publisher : Hasanuddin University

The over exploitation of the international fishing activities does affect the sustainability of the local small-scale fishing industry. The small scale fishing industry sectors especially economic, social, ecological, and governance in Indonesia has not been well managed. The objective of this paper is therefore to analyze the causal relationships between the four variables using a path analysis technique. The results of this analysis showed that the economic factor has the largest effect on the small-scale fisheries system. Future studies should emphasized more on the economic variable to sustain the local fishing industry in Indonesia.
