  • Faktor-faktor Sosial Ekonomi yang Mempengaruhi Keputusan Petani Menjual Lahan

Sumaryanto, PSEKP - Bogor.

Policy formulation of farmland utilization requires comprehensive understanding of  the land market, including the factors affecting farmers to sale their farmland. This study aimed to identify the factors affecting farmer's decision to sale their farmland. The study utilized the data resulted from farm household survey on Research Consortium "Socio Economic Characteristics of The Farmer in Several Agroecosystems" held on 2008 in 28 villages within 7 provinces in Indonesia. Using logit model, the study show that the more educated labor force of farm households tend to increase the probability to sale the farmland. The negative factors to sale the farmland were higher contribution of farming both on household income and employment.

  • Implementasi Cyber Extension Dalam Komunikasi Inovasi Pertanian
Retno Sri Hartati Mulyandari1, Sumardjo2, Djuara P. Lubis2 dan Nurmala K. Panjaitan2. 1. Pustaka Bogor; 2. IPB Bogor>

Cyber extension is one of the agricultural innovation network development mechanism effectively for bringing into contact between research, development, and assessment institution with innovation disseminator (extension workers), educators, farmers, and other stakeholders group that have each need with various information kind and form, so can be collaborated and equipped each other. Many problems that stakeholders were known in cyber extension implementation can be divided into four major categories, are: 1) Management (commitment and policy not yet consistence and limited managerial capability in ICT area; 2) Infrastructure (low and instability in electric and limited internet connection network or communication infrastructure, widely regional broadness, and limited local government budgeting); 3) Human resource development (limited human resource development capability in communication and information technology application); and 4) Culture (low of culture in sharing information and knowledge and low awareness for usually to documenting the  information/activities/data that can be accessed and owned). In agricultural innovation communication network system through cyber extension based on information technology application, the District Extension Agency is  a bridge between information source within center organization with local stakeholders and at the same time act as a synergizing system. Besides to facilitate the local users and stakeholders in accessing agricultural information manually and electronically, District Extension Agency can be functioning as information accumulator related to indigenous knowledge from local information resource through Extension agency at Sub district level that collecting information and facilitating information material for field extension workers in each rural. Cyber extension is expected to support the extension revitalization especially in conducting the collaboration and networking agricultural extension with related institutions.

Nyak Ilham1, Supena Friyatno2, Erma Suryani1 dan Nunung Kusnadi1. 1. PSEKP Bogor ; 2. IPB Bogor..

Food security policies is not enough just based on the scope of the macro study, but also information from the micro-scope study, as aspects of the marketed surplus at farmer households level. The purpose of this study are: (1) to know the socioeconomic characteristics of farmers in the context of the marketed surplus of rice; (2) to know how to sale and grade of paddy production produced by farmers and their implications for the characteristics of marketed surplus of rice, and (3) to analyze the factors influences of that marketed surplus. The data used are household survey of farmers in the 9 provinces conducted in 2008. Analysis of data was descriptive approach with cross tabulation techniques and econometrics approaches with Ordinary Least Squares techniques. The results of the analysis show that: (1) along with socioeconomic development and infrastructure has changed the orientation of rice farmers from subsistence to commercial, however, the characteristics of subsistence is still attached; (2) most of farmers in rice agroecosystem in the rainy and dry seasons in Java and outside Java sell their rice at once sold in the form of harvest dry rice then followed by a gradual manner in the form of store dry rice; (3) the price of rice, total household income and land area are statistically significant effect on the level of 3 percent of marketed surplus in rice agroecosystem in Java, whereas in rice agroecosystem outside Java only the number of household members and land area are statistically significant each at level 1 percent and 10 percent; (4) Suggestion to improve the welfare of farmers is the development of rice-producing centers should focus on areas with irrigation systems and better supported by increased credit facilities, post harvest facilities such as dryer, blower and barns.

  • Zonasi Tanaman Jarak(Ricinus Communis. L) Berdasarkan Integrasi Model Numerik dan Spasial
Fadjry Djufry BPTP Papua. 

The research objectives to develop a crop simulation model of castor oil  (crop development, crop growth, water balance, and economic) with integration spatial model. The spatial model used  geographic information system base on crop simulation model for development of castor (Ricinus communis L). The system software is integrated between numerical and spatial model. Integrating process began from numerical analysis to got variable and parameter of the model that can convert to spatial. The numerical model that used to develop this system has fourth sub-model: water balance, plant development, plant growth and economic model developed by modifying of data input of numerical model becomes spatial data with geo-reference and computer algorithm changes. The result of integrating model could be used as decisions support system tool for agribusiness management of castor (cultivation, zoning and economic analysis) in Indonesia.

  • Tahapan Proses Perencanaan Pengkajian BPTP
Wayan Sudana, PSEKP - Bogor. 

To support the assessment in BPTP more accountable and results are quickly adopted by users. It takes a better assessment of planning, so the introduce technology  able to solve problems faced by farmers. Because the technology is suited to the  resources based, compatible with existing technology and market opportunities. The purpose of this paper is to suggest the stages of planning an activity assessment process, making it easily understood by researchers in BPTP. Assessment planning process initiated by the introduction of agricultural resources, problems faced and how to solve these problems through assessment. At the end of the planning activities need to be equipped with a matrix of Log Frame and the Road Map. So easy to carry out monitoring and evaluation of each sub-activities that had been developed.

  • Integrasi Multi Resolusi Citra Satelit Dengan Metode Sederhana Untuk Memonitor Kondisi Lahan
Rizatus Shofiyati, BBSDLP - Bogor. 

In order to monitor agricultural land condition, it needs a good time resolution satellite images. On the other hand, the small area of agricultural land ownership in Indonesia is needed satellite image that has good spatial resolution. Integration of multi-resolution is one of the solution. Integration of high time resolution but low spatial resolution images (such as NOAA AVHRR, MODIS) and high spatial resolution but low time resolution images (such as Landsat TM, ALOS) could be used in this study. Some methodologies can be developed from combination of two kinds resolution of satellite images. Some researches give good results visually or statistically. This article presence simple concept of integration of multi-resolution and some studies of it using satellite images for land monitoring.
