Hasil analisis dalam penelitian ini ialah Kondisi geografis di Indonesia yang sebagian besar cocok sebagai lahan sawah menyebabkan ketersediaan beras di Indonesia cukup besar. hal ini dibuktikan dengan persentase wilayah surplus beras di Indonesia lebih besar dibandingkan dengan wilayah defisit berasnya, yaitu sebesar 52,94% : 47,06 %. Sebagian besar Provinsi dengan klasifikasi defisit beras berada di Indonesia bagian timur, seperti Provinsi Papua, Maluku, NTT dan NTB, sedangkan provinsi dengan klasifikasi surplus beras dominan berada di Pulau Jawa, Pulau Sumatera dan Pulau Sulawesi. Jadi secara umum pada tahun 2018 sebagian besar provinsi di Indonesia merupakan wilayah surplus beras dengan sentra beras berada di Pulau Jawa, Pulau Sumatera dan Pulau Sulawesi.Kata Kunci : Ketersediaan; Kebutuhan; Beras; Surplus; Defisit
Jangkaran Village is one of areas in the Special Region of Yogyakarta that has mangrove forests. Mangrove forests have unique characteristics and values of natural beauty so that they have the potential to be managed into mangrove ecotourism, particularly in Pasir Mendit and Pasir Kadilangu hamlets. Since mangrove ecotourism management also involves the surrounding communities the purpose of this present study was to assess the extent of community participation and mangrove ecotourism impacts on the socio-economic conditions of the surrounding communities. The study was conducted with survey methods using questionnaire instruments to collect the data. The research subjects were people who are involved or not involved in mangrove ecotourism management. The number of respondents sampled with quota sampling method was 40. The data were processed into frequency tables from scoring with Likert scale to determine the extent of community participation. The data were quantitative-descriptively analyzed with the Spearman Ranking Test to determine the relationship of internal factors with the level of community participation and the T-test to see the differences in the community conditions before and after the existence of the mangrove ecotourism and the differences between those people who are involved and not involved in the mangrove ecotourism management. The results showed that the levels of community participation in mangrove ecotourism management was moderate during the planning stage (3.05), very high during implementation and benefit taking (4.24 and 4.60, respectively), and high during evaluation (3.56); the impacts of mangrove forest ecotourism management to the community condition in the forms of additional income generating activities related to mangrove forests and social interaction in the form of voluntary works before and after the existence of mangrove ecotourism were similar, i.e. 47.5%; there was binding regulation that was moderate adhered (52.5% ) by the community, and; there were social conflicts (67.5%). The T- test statistics showed differences in the community incomes before and after the existence of mangrove tourism and between those who are involved and not involved in the mangrove ecotourism management.
Agricultural sector is the main economic activity of the society and also the source of people economy strengthening. The purpose of this study was to determine the priority direction of the development of the agricultural sector, mainly to determine the most appropriate types of commodities for each land unit that serve as local agricultural base. AHP method was integrated with GIS technique to analyze as well as to create land suitability maps for food crops. The results showed that 25.4 percent of lands in Yogyakarta is highly suitable for rice, while only 16 and 2 percent, respectively, is suitable for groundnut and corn. The limiting factors to the land suitability for these three commodities were plant roots condition, nutrients availability, nutrient retention, and soil condition. Suitable lands for rice, groundnut and corn were distributed at Ledok Wonosari, Middle Slope of Merapi, Lower Slope of Merapi and Batur Agung.

Synthetic rainfall simulation using weather generator models is commonly used as a substitute at locations with incomplete or short rainfall data. It incorporates a method that can be developed into forecasts of future rainfall. This study was designed to modify a rainfall prediction system based on the principles of weather generator models and to test the validity of the modelling results. It processed the data collected from eight rain stations in zones affected by El-Nino Southern Oscillation (ENSO). A large-scale predictor, that is, SST prediction data in the Nino 3.4 region over the Pacific Ocean was used as the influencing variable in projecting rainfall for the following six months after the predefined dates. Rainfall data from weather stations and SST in 1960-2000 were analyzed to identify the effects of ENSO and build a statistical model based on the regression function. Meanwhile, the model was validated using the data from 2001 to 2007 by backtesting six months in a row. The analysis results showed that the model could simulate both low rainfall in the dry season and high one in the rainy season. Validation by the student's t-test confirmed that the six-month synthetic rain data at nearly all observed stations was homogenous. For this reason, the developed model can be potentially used as one of the season prediction systems.
Indonesia merupakan salah satu negara kepulauan terbesar di dunia. Luas wilayah perairannya lebih luas dibandingkan dengan daratannya. Kondisi ini mengakibatkan faktor distribusi menjadi hal prioritas untuk dapat mencapai ketahanan beras di seluruh wilayah Indonesia. Kegiatan distribusi beras di negara kepulauan memiliki tantangan tersendiri, sehingga diperlukan strategi khusus berdasarkan karakteristik wilayahnya untuk mencapai ketahanan beras. Berdasarkan analisis data dapat diklasifikasikan wilayah berdasarkan ketersediaan dan kebutuhan beras, serta jarak tempuh pemenuhan berasnya. Berdasarkan analisis menggunakan metode transportasi linier programing dan SWOT dapat diperoleh hasil masing-masing kategori tersebut memiliki strategi yang berbeda, yaitu strategi distributif, defensif, protektif, revolutif, progresif dan variatif. Kajian ini diharapkan mampu menjadi salah satu kajian yang dapat menjadi rekomendasi dalam menentukan kebijakan ketahanan pangan beras dari aspek distribusi.
Abstract. Pekalongan is one of the coastal areas of Java Island that is affected by tidal floods. Tidal floods have various impacts on the social and economic conditions of the community, thus affecting their livelihoods. The purpose of this study was to examine the impact of a tidal flood, the socioeconomic characteristics of the community and the survival approach of coastal communities in Pekalongan. This study was conducted using a purposive sampling method in two villages in Pekalongan Regency, namely Jeruksari Village and Tegaldowo Village, because these two areas are affected by tidal floods. The study was conducted by using in-depth interviews and focus group discussions (FGDs), as well as structured interviews. The structured interview sample consisted of 60 respondents who were selected at random using quota sampling. The analysis was using qualitative-descriptive and quantitative methods. The gathered data were then presented in tables, diagrams and maps. The results showed that tidal floods resulted in physical, economic, sociocultural, health, educational, and environmental damages to the communities in both villages. The majority of the community members only have an elementary school education and primarily work as labourers. There is a difference in the amount of family income between the two villages, where the average family in Jeruksari Village has a higher income (IDR 3,465,300 per month) than the average family in Tegaldowo Village with total household income of about IDR 2 million per month. The most frequently used approach for survival in both villages is what is known as the survival strategy, i.e. a strategy to meet the needs of life at a minimum level to survive.Keywords: Survival strategy, tidal flood, Pekalongan coastal area. Abstrak. Pekalongan merupakan salah satu wilayah pesisir Pulau
