This study aims to determine the effect of different priming methods on the viability and early growth of upland rice under drought stress. Priming is an important approach to improve the resistance of upland rice plants to drought stress from the germination phase to growth, especially on sub-optimal land. There are several efficient priming methods as seed pretreatment to increase germination and tolerance to drought stress. An effective priming method is needed to increase the germination and growth of upland rice seedlings for application in dryland agriculture. Therefore, an experiment was conducted at the Seed laboratory of Pangkep State Polytechnic of Agriculture, Indonesia, from September to October of 2022 to investigate the effect of several priming methods on the germination and growth of upland rice seedlings under drought stress. The experiment consisted of 2 stages, germination testing and seedling growth phase testing with the addition of water stress treatment. Experiment 1 was conducted in a completely randomized design (CRD) with four replications, including Control (no priming), Osmopriming with 15% and 20% PEG solution, Redox Priming with 3% and 6% H2O2 solution, and Organic Priming using 50% and 75% Moringa leaf extract. Experiment 2 was conducted using a two-factor of factorial in Randomized Block design (RBD) with three replications. The first factor is the Seedling results of stage 1 experiments (selected the best of each priming method) includes 4 treatments each Control treatment, Osmopriming with 15% PEG solution, Redox Priming with 3% H2O2 solution, and Organic Priming with 50% Moringa Leaf Extract. The second factor is the level of Drought Stress conducted by 100%, 60%, and 30% of Field Capacity. The results showed that the priming method with Osmopriming 15% PEG solution gave the best results on Seed germination percentage (87.5%) followed by Organic priming with 50% Moringa Leaf Extract (SGP 85%). Under drought stress conditions with 30% field capacity, the highest increase in proline levels was observed with H2O2 redox priming 3% (10.3 µ-mol. g-1 ), while the average root growth of all primed seedlings showed better root growth than seeds without priming treatment. Seed priming gives better results on the growth and physiological activities of upland rice at several levels of drought stress, in the early growth phase of seedlings
Management of cassava in the village Baroanging, District Bangkala Jene'ponto district by farmers are not optimal and do not fully apply the recommended technology innovation so that although productivity is not too low, but still need improvement management, especially the system of cultivation. Cassava plant in the village only be used as plant-stream, but it can help the economy of the community. Because in addition to getting the results of rice crops also get additional income from planting cassava. However, income from farming of cassava is still very low because they only sell in the form of logs, they have yet to diversify the preparations of such products. Though cassava processing easy to do and relatively higher than the price of cassava spindles. One of the diversification of cassava processing is the manufacture of flour Making Flour mokaf mokaf this could be a new business opportunity for cassava farmers. So as to increase the income of cassava farmers. Objectives and targets outcomes to be achieved from the science and technology activities for the public are: 1) the target output short term that will be produced are: (a) Partner skilled in cassava cultivation organic technology use proper cultivation, (b) Partner know the benefits cassava is widely especially benefits flour mokaf, (c) Options were able to produce flour mocaf itself, 2) Target outcomes long term that will be produced are: (a) changing the mindset of farmers, from just farming cassava into the mindset of making these plants be a promising business opportunities, (b) the District Bangkala will be mokaf flour production center, (c) Formed new entrepreneurs that produce flour mokaf. Approach methods are offered to support the realization of the program consists of three methods, namely; (1). Participatory extension, (2) Training (demonstrations and practice activities by participants), (3) Mentoring, coaching the participants by the implementation team, and (4) Mentoring. A. PENDAHULUAN Kecamatan Bangkala adalah salah satu kecamatan di KabupatenJene'ponto yang cukup dikenal dengan komoditas tanaman ubi kayu (singkong).Masyarakat desa di wilayah ini hidup dari bertani/ladang, serta memanfaatkan hasil produksi tambak berupa garam. Tofografi wilayah dari dataran rendah sampai menengah,terhampar luas tanah kering yang terdiri atas tegalan seluas 5.746,01 Ha sedangkan tanah sawah hanya seluas 2.109,71 Ha dari total luas wilayah (BPS Kabupaten Jene'ponto, 2014).

The development of sustainable superior food commodities requires planning that can accelerate competitiveness and regional potential in the form of spatial-based data. This research will determine the leading commodities of the food crops sub-sector in Pangkep Regency, South Sulawesi. The data used are secondary data series of crop area in the period 2014-2018 and primary land suitability data. The analysis was carried out in two stages: i) suitability analysis of superior commodities which included conformity analysis with commodity regional map, matching sector analysis (LQ), employer absorption analysis (Shift Share), analysis of marketing coverage ii) Analysis of selected superior commodities will be developed using 3 stages of analysis, namely: 1) identification of commodities cultivated in the sub-district, 2) analysis of the economic value of superior commodities (LQ analysis, differential shift analysis, trend analysis), 3) determining superior commodities according to economic value analysis. The results of the study showed there are three main commodities, namely paddy, maize and soybeans, food sub-sector commodities and the area obtained through the process of overlaying land suitability data using GIS. The overlay results obtained an area of paddy development area of 6,440 ha, maize covering an area of 5,103 ha, and soybean covering an area 2,762 ha. The results are presented in the form of regional maps that are very detailed and effective in providing information about superior commodities and their suitability for their distribution areas.
One of the major obstacles in increasing the agricultural production yields is the inappropriate management of land use due to the differences of land biophysical characteristics in each region. Therefore, it is necessary to have spatial-based land use management that is appropriate in handling agricultural land. This research aims at structuring geospatial information of food land biophysical characteristics and food land appropriateness (potential and limiter) for food plants development in Pangkep Regency. This research uses the up-to-date approach of multi-scale observation, so the problems becoming the restricting factors of productivity can immediately be overcome. The method used consists of 2 stages, namely stage 1, analysis of food land (biophysical) climate and land characteristics through land survey, laboratory analysis, and land characteristic spatialization; stage 2, analysis of food land appropriateness (potential and limiter) using land appropriateness method of fuzzy set / FAO, satellite image information extraction, ground truth, and ground sampling. The results of the research are in the form of geospatial information of food land biophysical characteristics and food land appropriateness (potential and limiter) for food plants development in Pangkep Regency.
