International Journal of Agriculture System (Int. J. Agr. Syst.- IJAS) is published by Hasanuddin University (UNHAS) twice a year in June and December. This journal is an academic, citation indexed, and blind peer-reviewed journal. It covers original research articles, short notes and communications, reviews (including book), concepts, commentaries, and letters on a diverse topic related to agricultural systems including forestry, fishery/marine, and animal sciences. The aims of this journal are to provide a venue for academicians, researchers, and practitioners to share/discuss theories, views, research results, on issues related to the science, engineering and technology, and humanities in agriculture development, management, and issues in agricultural systems, particularly in the tropics. However, any other articles related to non-tropical agricultural systems are also welcome.

Abstract

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.

Abstract

Prices of agricultural products and poverty relationship are the two types of standing issue to solve. This paper tries to argue that price of agricultural products (hereafter, agricultural price) and poverty are strongly related. We employed Correlation (intermediate step) and Path (final step) in the analysis procedure. The results show that, first, the association degree between agricultural input (note as well, that price is crucial factor to get input) with poverty approaching 70%, indicating that agricultural input is good-fit in explaining poverty.  Second, the higher the frequency of getting agricultural extension, and price information for various inputs (and output) in agriculture, the higher the crop productions (agricultural sector, in broad sense) will be gained.  This indicates these two variables (inputs-outputs prices) can also be expected to be important instruments in increasing smallholders’ income and in turn help them living above poverty line.  Farmers household income is strongly affected by prevailing market price. Agricultural price is functioning as intermediate part of income calculation. It is clear that price of agricultural products has a strong linkage with rural poverty alleviation in the country.

Abstract

Local rice is rice that has been cultivated for generations by the community and commonly cultivated without using chemical inputs. Endophytic fungi are fungi that live in the plant tissue and does not cause disease symptoms in the host plants. This study aimed to molecular identifying isolates of MDTA and MDTB endophytic fungi which have been isolated from the local Pulu Mandoti rice plant tissue and growth test on the four types of culture media those were synthetic PDA, natural PDA, MPA, and MEA. The fungi DNA isolation using DNesay Kit. DNA sequencing analysis using the mega BLAST program showed that the MDTB fungus has similarities to Podoscypha bolleana strain 32034 no accession JQ675334 and Podoscypha bolleana strain 32032 no accession JQ675332, whereas the MDTA fungus has similarities to Coprinopsis cinerea A2S3-5 isolate and Coprinopsis cinerea strain CNRMA / F 07-32. The best culture media and sporulation of endophytic fungi is MPA media. This research is the first study to molecular identifying with endophytic fungi from local rice and viability test on the four types of culture media. The results of this study contribute to the diversity of local rice endophytic fungi in Sulawesi.

Abstract

The trend of rice productivity and its stability in Badung Regency are presented in this study. The area is a tourism-based economy without leaving the role of rice production to feed the people.  Time series data were collected from five sub districts covering 53 villages during 2008-2016 due to the completeness of the data. Variability of the data was observed from the coefficient of variance (C.V.) to decide rice productivity stability. This study also observed correlation between rainfall and rice productivity in the area. Result of the study shows that rice productivity trend in Badung Regency tend to decline during nine years of observation especially in 2014-2016. Three sub-districts had stable condition, while two sub-districts in tourism area contributed to the decline of this matter. Analysis using bi-plot revealed that there is no significant correlation between rainfall in sub-district and rice productivity, implying that water is available throughout the year.  In terms of stability, majority of villages (69.81%) had stable condition of rice productivity ranging from middle and high category. Other 30.19% villages were categorized as unstable ranging from low to high productivity. This condition showed that Badung Regency were able to maintain stability of rice productivity during nine years of observation. Implication of this study is to pay more attention to two sub districts in tourism area to improve their rice productivity such as implementation of good agricultural practices.

Abstract

Mycorrhizal fungi that are capable of adapting and resistant to heavy metal contaminated environments have received special attention for phytorhizoremediation researchers. The aim of the study was to explore native mycorrhizal fungi from areas contaminated with heavy metals to be used as starter biological agents in the phytorhizoremediation program. This research was carried out in two phases, i.e. rhizosphere sampling of Polypodium glycyrrhiza, Sumasang sp (local name) and Spathoglottis plicata at coordinates 2O31'57,6"S and 121O22'50,7"E. Rhizosphere of Chromolaena odorata, Melastama affine and Nephrolepis exaltata at coordinates 2O31'53,5"S and 121O22'35,4"E, Sorowako, Indonesia; While the other phase is isolating and identifying mycorrhizal spores in the Microbiology Laboratory, Research and Development Center for Environment and Forestry in Makassar, Indonesia. The results showed that be discovered three genus of mycorrhizal fungi were able to adapt and resistant in areas contaminated with Cr, Co, and Cu, i.e. 44.44% to 75.86% Acaulospora sp; 9.52% to 44.44% Gigaspora sp, and 3.38% to 19.05% Glomus sp.  which could be used as source of inoculum in Phyto-rhizoremediation program.   We recommend using native mycorrhizal fungi combined with endemic plant of location to rehabilitation heavy metal contaminated soils.
