The decrease of Indonesian pepper production caused by the decrease of productivity in production centre. Many problems faced by smallholders. To find out the real problems of pepper cultivation, a research had been carried out in several production centre such as Lampong, Bangka, Central and West Java with the objectives : a) to explore the problems and the performance of pepper plantation, and b) to identify technology adoption and technology needed. The research were conducted from May through October 2017. The method used was survey by collecting primary and secondary data. Primary data were collected through intervieuwing farmers, local government, businessman and extension workers. SWOT analysis and FGD were used to arrange policy recommendations. The problems found out in pepper development in all areas were a) there was limited technologies adoption of seeds, cultivation and processing, b) the shortage of superior varieties in production centre, c) the shortage of farmers capital because of very srare partnership between farmers and businessman, d) very high attack of pest and deseases so that farmers changed their plant into oilpalm and rubber, e) world price fluctuation that farmers could not manage the plantation, d) climate change and e) the shortage of farmers mastering the technology..

The achievement of expanding the area and volume of Indonesian palm oil production does not in line with the productivity. The productivity of Indonesian oil palm is inseparable from the age of the plants, most of which have exceeded their productive age. In addition, there are indications that the use of illegitimate seeds is relatively significant, causing yield gaps to potential productivity. Efforts to increase the productivity and sustainability of oil palm plantations have been carried out by forming a particular agency that collects and manages oil palm plantation funds. One of the programs to increase productivity and sustainability is the “Replanting of Smallholder Palm Oil (PSR)” with a grant scheme for participating farmers selected based on specific requirements. The progress of replanting realization is plodding. The target of 180,000 hectares per year cannot be realized. Accelerated breakthroughs without neglecting the primary mission of increasing productivity and sustainability are very urgent. This paper describes the results of a review on the importance of supporting seed institutional innovation for the acceleration of PSR towards increasing productivity and sustainability of Indonesian oil palm plantations.

In-vitro selection through tissue culture followed by field testing is one of the breeding methods to improve sugarcane varieties with drought-tolerant. This research aimed to obtain putative mutant sugarcane physically mutated using gamma-ray irradiation that passed the in vitro drought selection using PEG-selecting agents. This study was conducted from March to December 2016 using embryogenic calli of PSJT 941, PS 862, and BL varieties. The experimental design was the factorial randomized complete design with two factors, i.e. irradiation dose (0, 5, 10, 15, 20, 25, 30, 35 Gray) and PEG concentration (0, 10, 20%). The irradiated calli selected by PEG media had changed in color from yellowish-white to brownish and blackish and indicated the growth inhibition. The higher the dosage of irradiation and the concentration of PEG, the more calli with growth inhibition. Some putative callus mutants successfully passed in vitro selection using 10 and 20 % PEG, which showed tolerance to drought stress. The appropriate irradiation dose to produce tolerant mutants is 5 – 30 Grays for PS 862 and BL varieties, and 5-25 Grays for PSJT 941. To recognize the mutant response further, it is necessary for in-vivo selection at the greenhouse and in the field.

<p>National sugar production of Indonesia was relatively stagnant in the period of (2010-2014) it’s about 2,5 milion ton, due to low produktivity and sugar rendement as well as a big constrain on sugarcane extensification program. Cropping patern arrangement of sugarcane varieties is very important for increasing sugarcane productivity and rendement, to achieve self sufficiency in sugar production and consumption. The proportion of suitable varieties planting in sugarcane areas is unideal, tend to be excesive for late varieties. Principally, landscapping of sugarcane varieties is planting superior varieties of sugarcane (highly productivity and rendement) which appropriate to planting system, maturity character, harvesting time and processing of sugar in sugar manufacture to gain maximum yield. In Indonesia case for period of 2015-2019, the superior varieties should be choosed which having potencial produktivity &gt; 90 ton per ha and rendement &gt; 9 %, for all maturity group of varieties (early, moderate and late), which suitable for areas development of sugarcane. The important step in the near future are (1). Mapping and determining available superior varieties of sugarcane which suitable for planting at the time periods, (2) Producing seeds of superior varieties, (3) Developing areas of sugarcane, intensification of sugarcane cultivation and developing good management of sugarcane manufacture (PG), (4) Supporting research for producing the most superior sugarcane varieties which are more than superior varieties available in Indonesia at the moment., (5) Highly commitment of all stakeholder to apply the program of cropping patern arrangement for sugarcane varieties in all development areas.</p>

<p>Geographical Indications (GIs) certificate is required to protect specific flavors of crops in the given region. The study aimed to analyze the sustainability of the coffee farming system basis of Sindoro-Sumbing Java Arabica Coffee and Temanggung Robusta Coffee from the perspective of GIs protection. The study used survey methods with data collection techniques: (1) literature studies, interviews, and discussions with stakeholders, and (2) observation of the application of coffee cultivation and processing. The analytical methods used were (1) analysis of technical and institutional performance, and economic benefits with cross-tabulation and descriptive interpretation, and (2) analysis of the sustainability of coffee farming system using a multidimensional scaling approach. The results showed that the management of coffee farming in the Temanggung Regency was quite sustainable from the perspective of GIs protection with an index value of 66.88. The six dimensions of sustainability, showing fairly sustainable performance with an index of 59.22-74.99. This indicated that a comprehensive improvement is required to sustain the GI protection in Temanggung Regency, i.e., ecology, economy, ethics, institutions, social, and technology. Sensitive lever factors to improve the performance of each dimension are (1) adaptation to climate influence, land conservation, and cropping patterns for ecological dimensions, (2) commodity alternatives and price stability for economic dimensions, (3) logo inclusion on packaging, environmental maintenance, and the authenticity of products for ethical dimensions, (4) optimizing the role of GIPC for institutional dimensions, (5) involvement of stakeholders in the social dimension, and (6) improvements in harvesting methods for technological dimensions.</p><p><strong>Keywords</strong>:   Lever factors, arabica coffee, robusta coffee</p><p> </p><p><strong>Abstrak</strong></p><p>Sertifikat Indikasi Geografis (GI) diperlukan untuk melindungi rasa tanaman tertentu di wilayah tertentu.
