Abstract

Jember has 16.882 ha of coffee plantation, which  5.601,31 ha of them are smallholder coffee. Smallholder coffee is often identified has  low productivity and quality. This research wanted to know: (1)the advantage of smallholder coffee at District of Jember; (2) how to increase the advantage. Research was done on May – August 2012 (harvest periode) at Sub District of Silo, Sumberjambe, Ledokombo and Panti with 98 respondens which were choosen by  stratified random sampling methode.  The advantage was measured by  DRCR dan PCR, in order to increase the advantage using the result of Cobb-Douglas model of multiple regression analize on production function.  The  result show  that:  (1) there are two methode of post-harvest processing of coffee, they are wet process and dry process methode;(2) smallholder coffee at Jember has competitif and comparative advantage (PCR wet process methode is 0,3679 and dry process methode is 0,4261). (3) Balance fertilizing could increase  the advantage, but just comparative advantage (DRCR decrease to  0,4907 on wet process methode and 0,3566 on dry process methode), on the other side competitive advantage was a little decrease (PCR wet process methode is 0,5056  and  0,5089 on dry process methode).  Further more, balance fertilizing could increase the profit from IDR 17.804.906/ha/year to                IDR 21.103.109/ha/year on wet process methode and from IDR 8.965.371/ha/year to            IDR 17.112.813/ha/year on dry process methode.

Abstract

Bakteri selulolitik merupakan bakteri penghasil enzim selulase yang mampu mendegradasi substrat selulosa. Penelitian ini bertujuan untuk mengisolasi bakteri selulolitik asal tanah sampah, melakukan karakterisasi morfologi serta mengukur aktivitas enzim selulase ekstrak kasar pada bakteri selulolitikyang diisolasi pada salah satu tanah sampah di dramaga Bogor. Isolasi bakteri selulolitik dilakukan dengan menggunakan media selektif Carboxy Methyl Cellulose 1% (CMC 1%) dengan metode spread plate. Karakterisasi dilakukan dengan cara menumbuhkan isolat murni terpilih pada media CMC 1% selanjutnya ditetesi congo red 0,1% untuk menguji potensi selulolitiknya (potensi selulolitik ditandai dengan munculnya zona bening di sekitar koloni). Hasil isolasi bakteri diperoleh 4 isolat yang berpotensi mendegradasi selulosa. Indeks aktivitas selulolitik paling besar dimiliki isolat 10.1 yaitu 0.875. Uji secara kuantitatif dengan metode spektrofotometri DNS menunjukkan bahwa aktivitas enzim tertinggi terjadi pada masa inkubasi hari ke-9.

Abstract

Keberhasilan transformasi genetika pada tanaman padi sangat dipengaruhi oleh karakternya yang bersifat recalsitrant, terutama padi jenis indica yang banyak ditanam oleh petani di Indonesia. Oleh karena itu, optimasi metode selalu diperlukan sebelum melakukan transformasi genetika pada tanaman padi. Transformasi gen GUS sering digunakan sebagai sarana optimasi metode transformasi sebelum melakukan overekspresi gen yang sesungguhnya. Penelitian ini bertujuan untuk memastikan bahwa komponen transformasi gen melalui Agrobacterium tumefaciens dapat bekerja secara efektif pada tanaman padi. Penelitian dilaksanakan di Laboratorium Biosain Politeknik Jember dari bulan Maret sampai dengan Desember 2013. Konstruk gen GUS diperoleh dari Laboratorium Biologi Molekuler Universitas Jember. Padi yang digunakan adalah varietas Inpari 20 dari BPTP Malang dan CV Dongjin dari Korea Selatan sebanyak 20 biji dari setiap verietas. Hasil penelitian menunjukkan bahwa transformasi gen GUS melalui Agrobacterium tumefaciens berhasil menginfeksi eksplan. Eksplan yang diinfeksi tumbuh pada media seleksi antibiotik higromisin sampai umur 65 hari setelah infeksi. Hasil uji GUS menunjukkan bahwa gen GUS tidak terekspresi pada tanaman Padi. Hal ini menunjukkan bahwa ada kemungkinan DNA promoter dan plasmit pCAMBIA tidak kompatibel pada tanaman padi. Agrobacterium tumefaciens dapat digunakan untuk transformasi genetika pada tanaman padi, tetapi perlu DNA promoter dan plasmit yang kompatibel.Kata kunci: Optimasi, transformasi, gen GUS,  Agrobacterium tumefaciens, dan padi.

Abstract

A crucial problem faced by the target village community is the inhibition of changing the paradigm of the farmer community on the process of changing the mindset and action patterns in organic and conventional cultivation systems. In fact, the potential for the application of organic farming in the village is wide open, because the market for organic fertilizers and biological pesticides has started to run. The objective of the IbDM program is to optimize the supply of organic-based agricultural products towards healthy living. The implementation method used to find solutions to problems is in the form of social engineering and technological engineering approaches through socialization and training. The approach taken to the engineering process is in the form of a participatory approach, empowerment, and inter-entrepreneurial development in an effort to strengthen the capacity of community human resources by involving stakeholders through the village system model. The results of program implementation are as follows: 1) Socialization of the IbDM program with the results of partners understanding intellectually about the concept of this activity and are ready to participate in building an organic village; 2) The organic village cycle has been implemented properly with the formation of the Organic Farming Institute (OFI)) Al-Istiqomah; 3) Soil sample analysis has been carried out with 10 types of complete analysis and a 3 hectare demonstration plot mapping has been carried out; 4) A comparative study has been carried out to Gapoktan Al-Barokah Bondowoso; 5) Training has been carried out on the manufacture of organic materials; and 6) The results of the participatory review showed the achievement of success indicators of 65% and OFI performance of 30.23% or semi empowered and ready to go organic.

Abstract

[PERFORMANCES OF TEN SOYBEAN VARIETIES AS INTERCROPPED WITH SUGARCANE]. An intercropping system between soybean and sugarcane may be an alternative to increase soybean production in Indonesia, but not all soybean varieties are suitable for intercropping system as different soybean varieties may perform differently under intercropping system and monoculture system. Therefore, suitable soybean varieties for intercropping should be identified to warrant the higher crop productivity. This study was conducted to to compare the growth and yield performances of ten soybean varieties in monoculture and soybean-sugarcane intercropping systems. The experiment was laid in a Split Plot Design with three replications. The cropping systems (monoculture and intercrop) were allotted in the main plots, while the soybean varieties (Gepak Kuning, Kaba, Wilis, Tanggamus, Burarang, Sinabung, Anjasmoro, Agromulyo, Ring-1, and Gema) were assigned as the sub plots and allotted randomly in each main plot. On overall, the intercropping system had significantly reduced the soybean pod number, seed number, wight of 100 seed, and, seed yield/plant, but increased plant height as compared to the monoculture system. The exceptions were observed for seed number and weight of 100 seed. The reduction of seed number was not significant on Agromulyo and Dering-1.On the other hand, Anjasmoro and Dering-1were the only varieties showed significant reduction in weight of 100 seed. Kaba, Willis, Tanggamus, Burarang, Sinabung, and Dering-1 showed their consistant performormances across the cropping systems. However, the higher seed yield/plant in both systems was observed on Gepak Kuning, Willis, Burarang, Agromulyo, Dering-1, and Gema.

Abstract

In order to compare transient expression of gus gene driven by CaMV 35S and rice ubiquitin RUBQ2 promoters, a DNA transformation was conducted using embryogenic callus and suspension cultures of sugarcane. The transient gus expression was observed by histochemical staining method. The histochemical observation of GUS activity after co-cultivation showed that RUBQ2 promoter produced high level of clear blue spots both in embryogenic callus and suspension cultures, while the CaMV35S promoter was not detected. The suspension cultures slightly increased transient gus gene expression compared to embryogenic callus. However, the histochemical analysis of regenerated putative transformant plants after 5 successive cycles on the selection medium showed no blue spots of gus gene expression. PCR amplification of DNA for CaMV35 or nptII in putative transformant plants confirmed that there was no integration of the transformed gene in the genome DNA. The results suggested a possibility of somaclonal variation with callus propagation, thus did not produce transformed plants. To avoid the somaclonal variation, the transformation was conducted using in vitro plants and multiple shoots without intervening callus phase. Histochemical observation of infected materials after co-cultivation showed that almost all of the infected materials partially exhibited blue color in the basal region. In case of in vitro plants, they rapidly grow and multiplied in the selection medium, thus the method provided an excellent system for the transformation in sugarcane. The results suggest that in vitro plants as well as multiple shoots need further investigation to be used as target tissues for Agrobacteriummediated transformation in sugarcane.
