Citrus nursery is one of the upstream sectors that is significant to support citrus agribusiness in Sambas regency as citrus production center area in West Kalimantan. Several programs have been conducted to increase the capacity and technology adoption of disease-free certified citrus seedling producers. Therefore, the objective of this study was to examine the implementation of technology support for disease-free certified citrus grafted seedling production through mentoring programs to increase the knowledge and skill capacity of the seedling producers, as well as to evaluate the adoption level of the certified citrus seedling producers towards the recommended technology for disease-free certified citrus seedling production in Sambas Regency. The mentoring programs were carried out by training and establishing a model of citrus Bud-stick Multiplication Block. The evaluation of the adoption level of recommended technology was carried out by conducting surveys before and after the mentoring programs. The adoption evaluation of the recommended technology components comprised of the use of polybags during the whole production process, sowing rootstock seeds correctly, nucellar selection, transplanting, the use of bud-stick from Bud-stick Multiplication Block, Grafting and optimum maintenance. The evaluation results indicated that several technology components got an increase in the adoption rates after the completion of the mentoring programs. However, there were still few technology components that did not experience changes in the rate of adoption.

Appropriate and integrated land management technology in utilizing swamp land with optimal and sustainable productivity is needed because the swamp ecosystem is naturally fragile. The development of intercropping rice and citrus on tidal land needs to be supported by the application of cultivation technology and institutional strengthening of farmers so that the results obtained can be optimum and sustainable. Common problems that arise in the use of tidal land for agriculture include a variety of overflow and inundation conditions, very diverse types of soil with varied and low fertility levels, soil acidity and high potential for pyrite toxicity, variety of peat thickness and maturity level, and the condition of farmers who are still weak both in terms of skills and capital. This paper discusses the intercropping potential of citrus and rice to increase the productivity of swamps in Indonesia, the environmental and technical constraints, and strategies in proper and integrated land management.

<p>Downstreaming information of Indonesian Agency for Agricultural Research and Technology (IAARD) technology is carried out, among others, through the Multi Channel Dissemination Spectrum (MCDS). The SDMC employs various dissemination channels and actors to accelerate technology dissemination. MCDS discussions at the operating level are limited especially on how it contributes to more technology adoption. Referring to the Agricultural Innovation System, an innovation arises due to support of various subsystems ranging from technology providers, carriers, users, markets, policies, and interactions among subsystems. Likewise, the MCDS should be supported by its subsystems for an effective dissemination. This paper aims to contribute ideas on subsystems requirements in the implementation of the MCDS and how these subsystems can drive the delivered technology information to be adopted by users. The supporting subsystems (planning, approaches in the implementation process, policies, infrastructure) for technology implementation are essential in dissemination activities. As a system, MCDS does not only focus on delivering IAARD’s technology information, but the success of technological innovation must be supported by dissemination planning and its subsystems, technology application ecosystem, and interaction between potential users and technology producers.</p>

Selection Chili powder is one of chili product diversification form that can be a solution to solve the problems when chili production is abundant. This study aimed to test the potential of The Indonesian Agency for Agricultural Research and Development (IAARD’s) chili varieties as chili powder raw material. The research was conducted at IVEGRI from September to December 2020. A completely randomized design was applied with 10 treatments and 3 replications. The treatments consisted of 10 registered IAARD’s varieties. The results showed that there were two main components that influenced the diversity between tested varieties, the first main component (powder yield, moisture content, spiciness level, fruit diameter, thickness of fruit skin and weight per fruit) were 62.7% and the second main component (levels of vitamin C and fruit length) were 15.7%. The chili varietes that have the best yield of powder and spiciness were Lembang-1, Kencana, and Pancanaka. Meanwhile, Branang had a goodlevels of flour, spiciness, and vitamin C. By considering the parameters that are closely related to chili powder production, the potential varieties as chili powder raw material are Lembang-1, Kencana, Pancanaka and Branang. Further research is still needed to test the potential chili varieties as other processed.
