Research on the Effects of International R&D on Carbon Productivity in China: Empirical Study Based on Dynamic Panel Dawei Gao; Haisong Nie; Marina Takeyasu
International Journal of Agriculture System VOLUME 6 ISSUE 2, DECEMBER 2018
Publisher : Hasanuddin University

At present, nearly 70% of the world's new increase carbon dioxide emission comes from China. Technology is the key power to develop low-carbon economy. Because of the shortage of independent　R & D and the relative backwardness of low-carbon technology,　Chinese need developed countries’ R&D capital and advanced technology to promote low-carbon technologies. Based on the panel data from Chinese 30 provinces from 2001 to 2014 and dynamic panel model, this paper researchs on the effects of international R&D on regional carbon productivity in China. The empirical results show that, the technology spillover effect of FDI and import trade can improve carbon productivity, and imported technology contracts play a positive role on carbon productivity, but not significant. There is a significant positive correlation between independent R&D and carbon productivity. Finally, the corresponding policy is put forward according to the conclusions

Publisher : Hasanuddin University

Upland agriculture faces threats in the ecological crisis that will affect the sustainability of highland communities. The process lasts quite long because of external and internal influences, leading to ecological exploitation. Agricultural development, is closely related to the influence of government policy. Research focuses on discussing aspects of policy influence on the development of upland agriculture. The research is a qualitative study, using an inductive approach, the case of ethnic thorn communities in Enrekang Regency. The results of the study indicate that the three main policies that influence the development of upland agriculture are: 1). Political policy and government system, 2). Rural development policies and infrastructure, 3). Decentralization or regional autonomy, 4). Economic policies, especially investment and markets. The conclusion is that the development of agriculture is economically progressing in the shadow of the ecological crisis, drought, flooding and impact on humanitarian crisis, because it needs arrangements in land management and the application of technology for agricultural development.

Bacterial Antagonist Isolates in Controlling Bacterial Wilt Disease of Potato (Ralstonia solanacearum) in Aeroponic Cultivation System Nurbaya Nurbaya; Tutik Kuswinanti; Baharuddin Baharuddin
International Journal of Agriculture System VOLUME 1 ISSUE 1, JUNE 2013
Publisher : Hasanuddin University

The growing of potato plants in aeroponics system is considered as safe and ecologically friendly for producing natural, healthy plants and crops. However, it often faces with several constraints. Infection of bacterial wilt caused by Ralstonia solanacearum in the aeroponics cultivation system can spread rapidly through the nutrition flow and lead to plant death and crop failure. The objective of this study was to evaluate bacterial antagonist isolates belonging to Clostridium sp in reducing bacterial wilt disease of potato caused by Ralstonia solanacearum in aeroponic system and its effect on increasing the weight and number of potato tubers. The results showed that of the seven treatments tested on potato aeroponic system, treatment with a combination of isolates NS01 + G06 + S06 tend to be more effective in suppression of bacterial wilt disease (85%), increase the amount of seed tubers (162.5 tubers/treatment) and increase the average of tuber weight as much as 311.25 gr/treatment. It can therefore be concluded that a combination of three isolates of Clostridium sp i.e: NS01 + G06 + S06 had some synergic activities in potato aeroponic cultivation system.

The taxonomic study of a plant is an important aspect of plant research, as it allows the most complete view of the natural habitat of any plant species. The main purpose of the present work is to provide a detail investigation of the Passiflora edulis var. flavicarpa Deg. carried out from the month of April, 2020, growing in the area of Nakachari, Jorhat District, Assam, India. A complete workout on the different parts of the plant belongs to the family Passifloraceae is done to understand the significance of these features in systematic. Paper also reflects the various phytochemical constituents present in the Passiflora fruit also commonly known as Passion fruit which is utilized in pharmacology and by other ways in different ethnic groups of North Eastern India as a vital source of medicinal treatment. The findings clearly express that Passiflora species exhibits all advanced morphological characteristics of present day Angiospermae land plants and also reported that tendrils perform the role of physical support. Towards the end the study it is also concludes with the beneficial outputs of Passiflora edulis from the agronomical point of view that can be easily achievable if the input through cultivation would be uniform as well as dynamic. Based on the various literature surveys, it was found that such detail taxonomic works on the species were not studied and recorded from the study area earlier. Such comprehensive work on Passiflora edulis var. flavicarpa provides an empirical basis for the identification of the species.

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.

This study aimed to determine the effect of each component of cultivation technology application on the production of rice (Oryza Sativa L.) in South Sulawesi. This research was carried out in three rain-type sectors within South Sulawesi Province, namely Maros for the West Sector, Bone for the East Sector, and North Luwu for the Transitional sector. A study was conducted from December 2019 to January 2020 in the form of a survey (study literature, observation, and interviews), with the selection of samples carried out purposively to 90 respondents. Data analysis employed multiple linear regression with SPSS software. The results showed that the average rice production in Maros, Bone and North Luwu regencies, South Sulawesi, was still relatively low, Maros Regency was 7,032 kg per ha, Bone was 5,020 kg per ha and North Luwu was 6,497 kg per ha. The multiple regression equation for rice production in Maros, Bone and North Luwu Regencies, South Sulawesi is Y = 3354,185 -17,751X1 – 4,044X2 +36,839X3 . Factors from the aspect of cultivation technology application can increase rice production. Variables of cropping system, irrigation system, and fertilizer dose had a significant effect on rice production, while the variables of varieties and harvest time did not have a significant effect on rice production.

The integration of the export and import market scan be reflected not only by the relationship between the market price and its imports, but it also can be reflected by the relationship between the market prices of imports and exports. The objective of this study is to analyze the degree of integration of Indonesia’s natural rubber prices in the international market. The data used in this research is secondary time series data in 1980-2013 from IRSG, BPS, FAO, Gapkindo, UN Comtrade, BI, and the World Bank. The method of analysis using the index of Market Connection(IMC) to measure the index of market integration between the price of natural rubber in China, Japan, Singapore, and South Korea as a follower market and the price of natural rubber in the reference market(market leader) in this case is the United States. The results showed that Indonesia’s natural rubber prices in the international market is not integrated with China, Japan, and South Korea for the short term but it may be integrated in the long-term. The result seem to different to the Singapore that it market being integrated with the international market both for short term and long term periods.

Aceh Singkil west coast of Northern Sumatra was affected by natural catastrophes both tsunami and coastal deformation. Apparently most of the inter-tidal vegetation communities suffered because of the inundation intensity and duration changed. Investigation was carried on the structure and composition of littoral and mangrove forests in Singkil coast for 52 and 49 months after the 2004 and 2005 natural catastrophes, respectively. In each vegetation type, data were collected from four sampling plots, each measuring 30 m x 30 m. The sampling plots were separated into 10 m x 10 m sub-plots for matured trees and 5 m x 5 m sub-plots for smaller trees or shrubs. All plants within the subplots were identified and counted. Pure stand of littoral forests were dominated by Casuariana equisetifolia in the mature stage and Cerbera manghas in regeneration stages as natural regeneration. In the mangrove area, most of the mangrove trees such as Bruguiera gymnorrhiza, B. parviflora, and Rhizophora apiculata dead. Sonneratia caseolaris was higher survival rate compared than mangrove trees. B. gymnorrhiza seedlings were growing well. Mangrove palm Nypa fruticans populations were recorded growing well and with a good resiliency and persistence. In fact some of coastal vegetations both in coastal dry lands and in wetland forests have a good capacity to naturally restore and grow after the environmental destruction. From ecological point of view, these plant species should be selected for rehabilitation program in the natural catastrophes both tsunami and coastal subsidence as the impact of large earthquake could be reduced.

International Journal of Agriculture System VOLUME 4 ISSUE 2, DECEMBER 2016
Publisher : Hasanuddin University

The objective of the study was to identify the effect of Trichoderma viride andSaccharomyces cerevisiae inoculant on chemical compositions, digestibility, and theobromineconcentration of fermented cocoa pod. This experiment consisted of four treatments,namely cocoa pods without fermentation as control (R0); fermentation of cocoa pods withinoculant T. viride (R1); fermentation of cocoa pods with inoculant S. cerevisiae (R2); andfermentation of cocoa pods with inoculant T. viride and S. cerevisiae mixed culture (R3).Each treatment had 3 replicates, and then was fermented for 10 days. Variables observedwere the chemical compositions i.e dry matter (DM), organic matter (OM), crude protein(CP), ether extract (EE), crude fiber (CF), nitrogen free extract (NFE), fiber fraction (Neutraldetergent fiber and acid detergent fiber), in vitro digestibility, and theobromine concentration.Data were analysed by one-way analysis of variance and followed by Duncan’s new multiplerange test (DMRT), if there were any significant difference. Results showed the inoculumaffected (P<0.05) the chemical composition, fiber fraction and in vitro digestibility. However,theobromine was not detected on cocoa pod without fermentation and fermentation.Compared to group R0, inoculation with T. viride and S. cerevisiae mixed culture (P<0.05)resulted in higher DM concentration (92.78% vs 89.72% respectively), higher CP (7.43% vs5.63% respectively), higher NDF (79.41% vs 61.18% respectively), higher ADF (73.04%vs 47.94% respectively), but was not significantly different on DM and OM digestibility(21.22% vs 22.24%, and 22.67% vs 24.31% respectively) than cocoa pod without fermentation.It is concluded that inoculant T. viride and S. cerevisiae mixed culture increased CPconcentration, but had no effect on in vitro digestibility.

Can Access to Social Facility Help Poverty Reduction in Agricultural Sector? Evidence from Indonesia Muhammad Arsyad; Yoshio Kawamura; Syarifuddin Yusuf; Muh. Hatta Jamil; Andi Nuddin; Alimuddin Laapo

Poverty in agricultural sector is still becomes a serious issue in developing country, and Indonesia is no exception. Our previous study was focusing on poverty and income (income poverty). This paper, however, deals with a substantive question, can access to social facility (non-income) help poverty reduction in agriculture? The study (also) utilized previous model of Dimensionality Test, Factor and Path Analysis to answer the question. The results show that the higher government transfer source income in terms of Social safety Net Program, the more money for smallholders will be. This leads us to argue that transfer income from the government to the smallholder community can be still considered in maintaining smallholders’ daily life, means helping them move out poverty. The better access to social services such as primary public health center (called PUSKESMAS), clean water supplied by PDAM (Local Government Division for Drinking Water Affairs) and secondary school is, the higher the household income will be. Thus, if PUSKESMAS, primary and secondary schools as well as clean water sources are nearer, the less time and money will be spent to travel, then the more household income at hand will be saved. In other words, distance and degree of utilization appear to be a crucial part of these interpretations above. Therefore, it is reasonable to say that the better the access to social services such as public health center, schools and public clean water, the more household income will be and in turn it will alleviate the poverty of smallholders. It is clear that providing better access to social facility can help poverty reduction in agricultural sector.
