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.

Marica goat is an endemic species that can be found only in South Sulawesi, Indonesia. It has been reported by the FAO as endangered species because its number of population has been significantly decreased. Domestication by local people has been done by cultivating them with Kacang goat that leads to an interbreeding process. Conservation of the goats must be done immediately due to its rapidly decreasing population. However, accurate identification and quantification of the goat by DNA analysis is highly important. The objective of this study is to determine the differences amongst marica, kacang and Capra hircus, C. caucasica and C. falconeri from the GenBank. The sequence of the mitochondrial DNA (mtDNA) at d-loop region of 30 Marica goats and five Kacang goats from three districts in South Sulawesi were investigated. Their nucleotide sequences were compared with the sequence of the GenBank’s Capra sp and were analyzed using Dendogram neighbor joining tree. The results showed that there were a few nucleotide differences between some Marica and Kacang goat that were located at 20, 840 and 980bp. In addition, both nucleotides sequence have short genetic distance compared to C. hircus. However, comparing with other Capra sp, the distance was significantly far. Meanwhile, according to the dendogram, it was found that all Goats and Capra sp came from the same ancestral lineage. It can be concluded that Marica and Kacang goats could be very closely related with C. hircus but they were different from the C. caucasica and C. falconeri.

Potato production in Indonesia has been declining while demand for potatoes remains increasing. One main reason of the decline is the lack of availability for good potato seedling. To optimize the growth of potato seedling, some plant extracts as exogenous growth regulators may be used. This experiment was aimed to select the best plant extract as exogenous growth regulator for potato seedling growth and study the underlying physiological process. Seven plant extracts as exogenous growth regulators for potato seedling were used as treatments namely: water as a control, corn grain (Zea mays L.), onion (Allium ascalonicum L.), coconut water (Cocos nucifera L), snaps (Phaseolus vulgaris L), banana (Musa paradisiaca L.) and mung bean sprouts (Vigna radiata). The experiment was set in the form of randomized complete block design with three replications. Result revealed that one month after sowing, corn grain extract gave the best quality on the potato seedling growth based on percentage of live seedling (100%), seedling height (15.87 cm), number of leaves (9.40 leaves) and root length of the seedlings (13.39 cm). On the other hand, water treatment (control) showed the lowest growth quality on potato seedling indicated in all parameters as follow: percentage of life of potatoes seedling (74.44%), seedling height (3.66 cm), amount of leaves (4.27 leaves) and length of root (4.83 cm).

Forest inventories describe the quantity and quality of trees and other organisms of the forest and the characteristics of the land on which the forest grows. Thus, to manage the resource of the forest systematically, the forest has to be precisely identified and classified before implementing decisions. A study on the spatial distribution of mountain mixed hill dipterocarp forest tree species in Gunung Stong Forest Reserve, Kelantan, Malaysia was conducted using an airborne hyperspectral imaging technique to identify, tag and map tree distribution at species level for future sustainable harvest and management planning. The general objective of this study is to assess the capability and usefulness UPM-AISA airborne hyperspectral sensor in Pre-Felling forest inventory while the specific objectives are to identify, map and tag individual trees in Gunung Stong Forest Reserve, Kelantan. A Sobel filter was used to enhance the image followed by a Spectral Angle Mapper (SAM) analysis to classify the individual tree species within the study plot. A digital map of tree tagging was produced with the tree species identified were Kelat (Syzgium spp), Keledang (Artrocarpos spp), Mengkulang (Heritiera spp), Tempinis (Streblus elongatus), Keranji (Dialium spp), Tulang Daing (Callerya atropurea), Meranti Sarang Punai (Shorea parvifolia), Kembang Semangkuk Jantung (Scaphium macropodum), Bintangor (Calophyllum spp), Nyatoh Minyak (Sapotaceae spp), Mersawa (Anisoptera spp), Resak (Cotylelobium spp), Sepetir (Sindora spp), Temponek (Artocarpus rigidus) and Petaling. The mapping accuracy of 89.66% was attained in the 1 ha study plot. Tree tagging using airborne remote sensing has a great potential in the Pre-F inventory and should be integrated with a GIS database management for future decision in management, development and utilization of sustainable forest resource.

Assessment of Trees Outside Forest (TOF) in Selected Makiling Subwatersheds Jan Joseph V. Dida; Joseph C. Paquit; Cheamson Garret K. Boongaling; Gemmalyn E. Magnaye; Nathaniel C. Bantayan

Trees outside Forest (TOF) are trees, shrubs, bushes including palms that are found in the Food and Agriculture Organization (FAO) other land classification that can be agricultural, urban, or non-agricultural/urban. TOF provide various services and functions that are neither well documented nor given enough attention, hence the need to identify and assess them in agriculture and urban areas outside Mt. Makiling. A SPOT satellite image (2010) covering the Cambantoc, Molawin-Dampalit, and Tigbi subwatersheds of Mt. Makiling was used in the supervised classification of forests, lakes, agriculture, and urban areas. Areas that qualify as other lands were extracted using the classified land types as guides in GIS vector format. Using Google Earth imagery, other lands were digitized and assessed following the FAO decision tree algorithm for TOF and field checking was conducted to validate the tree height in the TOF criteria. Based on the GIS and field assessment, Tigbi and Molawin-Dampalit were found to have TOF on urban land that are mostly fruit trees cultivated for food, landscaping while Cambantoc has TOF on agricultural land and TOF on non-agricultural/urban that are used as farm windbreaks. Findings suggested that TOF contributed to the tree canopy cover in Makiling subwatersheds. Assessment of TOF can be used to account for the ecosystem services it provides which complement those that come from forests and other wooded lands. FAO also recognizes the importance of TOF for local and national food security. TOF, especially fruit trees, are important source of food products for the people.

A series of researches was carried out to obtain mutant of maize induced by gamma rays irradiation. This initial report was from a study confirming the best dosage of irradiation at 50% lethal dosage (LD50) conducted at the Laboratory of Seed Science and Technology, Faculty of Agriculture, Hasanuddin University, Makassar from March to June 2012. The research was set up using split plot design of the Randomized Complete Block design. Data were analyzed using analysis of variance. Results showed that: Gamma ray dosage affected maize seed viability. The higher gamma ray dosage used resulted inmore inhibiton of maize seed germination. The best LD50 irradiation to induce putative mutation (M1) in maize seeds tested ranged from 100-200 Gy. The genotype Lamuru maize irradiated at 100 Gy were superior and were more viable with a percentage germination of 87.22% and vigor index of 4.48.
