Lionardo A. 2019. Implications of direct regional head election on food security and suboptimal agricultural land policies in South Sumatra Province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019. Palembang 4-5 September 2019. pp. 535-545. Palembang: Unsri Press. The mechanism of direct selection of regional heads should have implications for the condition of food security which is more beneficial to the lives of people in South Sumatra. This is because for the people of Indonesia rice is a staple food that is difficult to replace. Thus the policy accountability will be the responsibility of the government to fulfill it every year. The direct election of regional heads should not result in a populist policy in agriculture. The new autonomy must have an impact on the problem of social, economic and community income that can meet basic food needs for people in South Sumatra. Food Security Policy that has long been rolled out has an impact on poverty in rural areas that are difficult to overcome, the government inevitably if it wants to improve the economy of farmers in rural areas must make a policy related to three components, namely improving the welfare of farmers, equilibrium of market mechanisms, and fairness of management of agricultural land. The implementation of Regional Regulation Number 21/2004 on the protection of sustainable food agriculture land must be on the agenda setting of the regional head's policy as the result of direct regional head election in developing the Food Security program for rural progress. Thus, the function of suboptimal agricultural land is agriculture to industrial areas. The purpose of this study is to look at the extent of the Implications of Direct Regional Head Election for Food Security and Suboptimal Agricultural Land Policies in South Sumatra Province.Keywords: direct election, food security, public policy

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 192-200. Palembang: Unsri Press. The price of a commodity is a very important factor that influences the decisions of producers in production activities, and consumers in their consumption activities. This study aims to build an ARIMA model for forecasting rice prices based on the quality of premium and medium rice. The study was carried out in Ogan Komering Ilir Regency as the center of swamp rice production in the South Sumatra Province. The ARIMA model of rice price was built using the Box Jenkins method with sequential data on weekly rice prices since the second week of March 2016 to the second week of September 2018. The results showed that the best model for the retail price of premium rice was ARIMA (8,1,0), whereas for medium rice retail prices, ARIMA (4,1,1) is obtained. The forecasting results show that the price of premium and medium rice in OKI Regency until December 2020 continues to increase.Keywords: ARIMA model, premium and medium rice, retail price

Riyanto D, Sukristiyonubowo S, Widodo S. 2019. Improving land quality by application of biochar and biofertility in corn cultivation of planting season III on Gunungkidul Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 400-408. Palembang: Unsri Press. Managing land resources and improving soil quality are currently urgent and very important for the continuation of future generations. Improvements in the quality of rainfed rice fields can be done, among others, by the application of biofertilizers and biochar. Biofertilizer is a group of living organisms whose activities can improve soil fertility. Biochar is a solid material obtained from the carbonization process of a biomass of agricultural or plantation waste. Biochar is a porous, high-carbon solid substance of more than 50%. The assessment of application biological fertilizers and biochar were carried out in Polaman, Wareng village, Wonosari district-Gunungkidul. The time of implementation in planting season III (June-September 2018) with the treatment as stated: (A) Control (without biological fertilizer and biochar) + 100% chemical fertilizer according to recommendation (325 kg/ha Urea, Phonska NPK 300 kg/ha), (B) Application of Biofertilizer (Agrofit) 400 g/ha, without biochar + 100% chemical fertilizer (C) Application of Biofertilizer (Agrofi), without biochar and 75% chemical fertilizer according to recommendation, (D) Application of rice husk biochar 2.0 tons/ha, + Agrofit biofertilizers and 100% chemical fertilizer (E) Application of Biofertilizers (Agrofit), and biochar 2 tons/ha + 75% chemical fertilizer. Each treatment was repeated 4 times. Irrigation utilizes were used 2 existing borehole wells and support by submersible pumps which are carried out in rotation on each cooperator farmer's land. The discharge of water in its well is 2.5 liters/second. The observation of maize growth plants at 20 DAP and 40 DAP and 60 DAP were shown that the treatmen B and D was the highest result in corn plant height and the amount of leaves compare to the others. While the yield of shelled corn showed that the combination of treatment with biochar application 2 tons/ha and agrofit biofertilizers+75% chemical fertilizer and application of biochar 2 tons/ha and 400 g/ha agrofit + 100% chemical fertilizer recommendation shows that the results are not significantly different, so it can be recommended that application biological fertilizers and biochar be able to save 25% chemical fertilizer. This treatment shown that was better results than control (farmer treatment) and treatment only giving biochar or biological fertilizers in single application.Keywords: biological fertilizers, biochar, corn productivity, land quality, rainfed rice fields

Budiharto W. 2019. Digital innovation in the smart farming industry: concept and implementation. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 31-37. Palembang: Unsri Press.Agriculture is one of the oldest industrial sectors ever created by humans. The FAO predicts that by 2050 the world population will be 9.6 billion. That means agricultural production must increase by 70% in that year in order to meet the needs of the population with this amount. Yet as we know that there is a classic problem of food namely the population increases but the amount of agricultural land is getting narrower. Therefore, increasing agricultural technology-based productivity is very urgent, one of which is based on the Internet of Things (IoT). IoT is the latest technology where devices around us can communicate with each other through the internet network. Wireless Sensor Network (WSN) technology was applied more broadly to IoT-based agriculture which came to be known as Smart Farming. The sensors used in agricultural land are used to determine the chemical condition of the soil, the quality of plant health and other useful information. Smart farming, which was originally called Precision Agriculture, is predicted to become a compulsory concept of agriculture in the future because of limited land. Smart farming utilizes technologies such as big data, machine learning, robotics and IoT to improve the quality and quantity of production in the agricultural industry. This paper gradually explains the concept of smart farming and its implementation in Indonesia.Keywords: concept, implementation, smart farming

Riswani R, Yunita Y, Malini H, Naufal AMM. 2019. Comparison of business characteristics and income of environmentally and traditionally rubber farmers in Musi Banyuasin Regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 318-324. Palembang: Unsri Press. Rubber commodities in South Sumatra, even though they have been cultivated with land area that tends to be larger than other provinces, but have not been balanced with production and quality, which is still low, due to the methods of exploitation and processing that are not yet ideal and have no environmental impact. It makes the prices and market demand fluctuate with a downward trend. The purposes of this research were to describe the comparability of environmentally rubber farmer and traditional rubber farmer, then followed by an analysis of the factors that influence them so that recommendations for improvements must be made. The research was using survey method with two gruops of respondent, so that primary and secondary data were obtained, which were processed using structured tabulations, calculated using mathematical formulas and tested with statistical tools. The results showed that there were differences in the use of production inputs and processing of Bokar products by rubber farmers who are environmentally sound and who are still traditionally trying to have an impact on the differences in prices received and income obtained significantly. From the results of the factors testing that influence the income showed that only the selling price factor has a significant effect on farmer income, while the selling price tends to be linier with the quality of production, so improving production quality is a priority solution in an effort to increase the farmer income.Keywords: income farmer, quality, rubber

Suparman S, Ardiansyah MA, Ikraman R. 2019. PNDF (Plant Nutrient-Direct Feeding), alternative solution to optimize sub optimal land use. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal 2019, Palembang 4-5 September 2019. pp. 508-512. Palembang: Unsri Press. Indonesia currently does have many choices in realizing national food security. Along with the increasing population and national food needs, land needs are also increasing for agricultural development. On the other hand, there’s considerrable potential land resources with a total land area of 190 million ha, around 160 million ha (84%) of which are sub-optimal land. With the increasing function conversion of land into industrial land and infrastructure, then to meet national food needs must use sub-optimal land. Among other things, land with acid soils, salt and peat is used as productive agricultural land. Sub-optimal land is land that naturally has low productivity, sub-optimal land needs to be treated in such a way as to achieve the intended purpose. Various sub-optimal land remediation techniques that have been carried out are in fact not yet effective in increasing crop yields. Scientifically, remediation techniques are experts explained ideal to do, but in practice it is difficult to apply in the field mainly due to the large amount of costs incurred by farmers to carry out remediation. By paying attention to the function of land as a supplier of nutrients and water, the Technique "PNDF (Plant Nutrient-Direct Feeding), which is directly supplying essential nutrients to plants, becomes the right alternative solution in optimizing sub-optimal land use" to realize national food security done by farmers so that cultivated plants get the necessary nutritional intake that takes into account the ecological impact and is also economically beneficial for farmers as the main actors. Keywords: land, remediation, sub-optimal
