Rice Production Modelling in Indonesia with the Spatial Autoregressive (SAR) Approach

The aim of this research is to find out how big the role of the farmer group members in increasing rice production at Korobhera Village, Meggo Subdistrict, Sikka District. The research has been done on April to May 2019. This is a qualitative study with purposive sampling considering the site was one of rice central production. The objectives of the study were to know : 1) how big the role of the farmer group members to productivity increasing in the area of research ; 2) the constraints faced by the members of the farmer group. Sample was done randomly using simple random sampling method with a total sample size of 50 people, who were the members of four farmer groups existed. The results of research indicated that the role of farmer group members in increasing rice production at the location of research was high, shown by the percentage of the accomplishment maximum score from average score in the amount of 75,65% (average score 87). The constraints faced by members of farmer group were quite similar, which were financial capital limits problem, uncaged livestocks and the availability of production tools was often not on time.

Punjab has emerged as an important rice-producing state in the country. The state with 1.53 percent of the geographical area of the country produces more than 11 percent of total rice production in the country. The production of rice in Punjab increased more than 10 times due to an increase in area and yield. The growth of a rice crop at such a high rate over 20 years in Punjab is indeed a rare phenomenon in the history of agricultural development in the world. Due to extensive cultivation of rice in Punjab, the state has been over-exploiting the groundwater, more than its recharge. Most of the tube-well dominated districts of the state, witnessed the fall in water table more than 20 to 30 cm per year. To dispose of the paddy straw, the farmers of Punjab generally opt for burning it. This practice of burning of paddy straw besides nutrient loss is posing a serious problem for the public health and transportation system. Rice has now become a problematic crop for Punjab state due to its ill effects on its natural resources, that is, the water and soil environmental degradation. The Punjab Agricultural University experts and other committees estimated that the total groundwater recharge from all sources can sustain/support only 16-17 lakh ha of paddy in Punjab. The area under the crop increased to 29 lakh ha which was unsustainable in the long run. The area under rice in Punjab should be stabilized at 16-17 lakh ha and the remaining paddy area should be shifted to other crops like pulses, oilseeds, maize, fruits, and vegetables, etc. requiringless water, to achieve proper water balance. Thus diversification of some area from paddy is in the interest of Punjab farmers, State government and the Central government for long term food security on a sustainable basis.

Abstrak - Produksi padi di Indonesia setiap tahun mengalami peningkatan, namun peningkatan ini belum mampu memenuhi kebutuhan nasional sehingga impor masih harus dilakukan. Salah satu masalah dalam produksi beras adalah penggunaan pupuk berlebih yang tidak hanya meningkatkan biaya produksi, namun juga merusak kondisi tanah. Aplikasi bakteri tanah sebagai Plant Growth Promoting Rhizobacteria (PGPR) dapat menjadi salah satu solusi terhadap masalah ini. Penelitian ini bertujuan untuk mengisolasi bakteri tanah dari 3 lokasi sawah daerah Bekasi, membandingkan keberadaan total bakteri pada ketiga lokasi tersebut, dan melakukan karakterisasi isolat berdasarkan karakter yang dapat memicu pertumbuhan tanaman. Dari ketiga lokasi, diperoleh total 59 isolat dan 5 diantaranya berpotensi sebagai PGPR karena kemampuan fiksasi Nitrogen, melarutkan Fosfat, katalase positif, dan motil. Dari ketiga lokasi pengambilan sampel, BK1 memiliki jumlah total bakteri terendah karena aplikasi pemupukan dan pestisida berlebih yang ditandai tingginya kadar P total, serta tingginya residu klorpirifos, karbofuran, dan paration. Kondisi fisik tanah BK1 juga didominasi partikel liat yang menyebabkan tanah menjadi lebih padat. Peningkatan jumlah penggunaan pupuk tidak selalu diikuti peningkatan produktivitas tanaman.

One of the problems in rice production is the use of excessive fertilizers that not only increase production costs, but also decreased the soil conditions. The application of soil bacteria as Plant Growth Promoting Rhizobacteria (PGPR) can be the one solution to face this problem. The objective of this study was isolate soil bacteria from 3 locations of rice field in Bekasi, compare the total bacteria in the three locations, and characterize isolates based on the character that can promote plant growth. From three locations, a total of 59 isolates were obtained and 5 of them were potential as a PGPRs due to its Nitrogen fixation activity, Phosphate solubilization, positive catalase, and motility. From three sampling sites, BK1 has the lowest TPC value because of excessive fertilizers and pesticides application which indicated by high total P levels, and also high chlorpyrifos, carbofuran and paration residues. The physical condition of BK1 soil is also dominated by clay particles which causes the soil more solid. Increasing of fertilizer application is not always followed by increased plant productivity.
