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

Smart irrigation system is an automatic irrigation and monitoring system on agricultural land with a sensor, automation, and control technology based on the Internet of Things (IoT). This system can reduce the agricultural activities that were previously performed manually into an automatic system with a reduced human supervision. Smart Irrigation systems that are widely developed used Arduino as the controller. Arduino still lacks in response, low durability, and sensitivity to temperature change, hence requiring frequent maintenance to avoid weather disturbances, insects, and others. This paper presents a development of a smart irrigation system using a Programmable Logic Controller (PLC) as the controller and a soil moisture sensor as a humidity condition measurement tool. The advantage of using PLC as a controller is more stable and has sensor compatibility with higher accuracy. Hence the results are more consistent and accurate. The PLC system is expandable, allowing for the inclusion of more channels for sensors and other measurement instruments. The developed system can collect data on soil moisture conditions, trigger valves, and perform auto irrigation using sprinklers, reducing or even eliminating the need for human intervention. The IoT collects data from sensors and updates the data into a database system, allowing users to monitor the land conditions in real-time. The developed system was predicted to save manpower (20%) and water usage (42.47%) compared to the conventional method. Keywords: Smart Irrigation; IoT; PLC; Moisture Sensor; Sprinkler

Abstract

Water is the most precious commodity that human being wanted, nowadays water is depleting due to several human interventions. In Kerala state, even though high rainfall is received, still water scarcity is faced during summer and soil erosion is higher. This watershed area is prone to water scarcity during the summer season and stream network become dry during that period. This clearly indicates that human interventions and unscientific agricultural activities may be the result. In this, study GIS and RS technologies are used to find and map the Soil and water conservation priority zones, also several action Plans where proposed. SOI Topo sheet were used to digitize the contours and DEM was created using that with ArcGIS 10.2.2 software. LULC maps were digitized from satellite image and using other parameters and suitable weight values, the weighted overlay was done to find out the Priority Zones. Cadastral Plot boundaries were overlaid for plot-wise priority zones and several conservation methods like gully plugin, check dams, vegetation bund etc. were proposed.

Abstract

Cibodas Botanical Garden (CBG) is an ex-situ plant conservation institution, maintaining living collection from various taxa including Rubiaceae. Most of Rubiaceae ornamental plants are introduced species with regard to their attractive characters. However, introduced species of ornamental plants is one of significant global plant invasion pathways. The aims of this research was to conduct inventory study of CBG’s Rubiaceae collection, to determine native and introduced species, and to bring out CBG’s native Rubiaceae potential as ornamental plants. The research was divided into two methods, field study and literature study. Field study was conducted by making inventory of Rubiaceae living collections and plant morphology observations. Literature study was conducted by obtaining data of plant distributions, utilization as ornamental plants, and also comparing domesticated species with CBG’s living collections. Results showed that CBG has collected 20 genera, 50 species and 116 specimens of Rubiaceae as living collections. There are 22 native species, 15 introduced species and 13 species that can not be determined. There are 5 species commonly utilized and cultivated as ornamental plants, 8 species are not known for their aesthetic characters but has potential as ornamental plants. These species are Gardenia pterocalyx Valeton, Hypobathrum frutescens Blume, H. racemosum (Roxb.) Kurz, Mycetia cauliflora Reinw., Pavetta montana Reinw. Ex Blume, Psychotria angulata Korth, P. montana Blume, and Wendlandia densiflora (Blume) DC. This study demonstrated that there is a promising potential from these lesser-known native Rubiaceae species for ornamental use. CBG should conduct more research about native species’s potential as ornamental plants.

Abstract

One of the efforts to increase rice production is by extensive farming through the utilization of marginal lands affected by drought. The present study aims to examine the influence of seed priming with PEG 6000 on rice seed germination and growth of rice seedlings in drought conditions and to group the rice varieties tested based on their tolerance to drought, and determine priming formulations for early adaptation of rice seedsthat can be used by farmers and industry.  The research was organized in the form of a Split Plot Design with Randomized Group Design. TheMain Plot is a rice variety, consisting of 10 levels, i.e., Inpari 31, Inpari 33, Inpari 36, Inpari 39, Inpari 40, Inpago 8, Inpago 10, Mekongga,Rindang 1 and Rindang 2. While the Split Plot is a concentration of PEG, which consists of 5 levels, i.e., without soaking as negative controlconcentration 0 g L-1 PEG as positive control, and 50, 100, and 150 g L-1 PEG-6000.  Each of these treatments is repeated three times, so thereare 150 observation units. Results showed that among the 10 varieties tested, there were 2 less tolerant varieties with scores of 5-10 (Inpari 31and Inpari 39), 5 varieties are quite tolerant with a score of 11-16 (Inpari 33, Inpari 36, Inpari 40, Inpagi 10 and Mekongga) and 3 varieties are very tolerant with a score of 17-22 (Rindang 1, Rindang 2 and Inpago 8) with priming concentrations of 100 g L-1 PEG-6000 for 36 hours.
