Abstract

Leather industries contribute significant problems due to the hazard wastes, that threat to environmental sustainability and to human health. The negative impacts are particularly caused by the chemical compounds used in the conventional process of the leather tannery, such as lime, sodium sulphide, chrome, etc. Enzyme is protein compound from biological system, that acts as catalyst (bio-catalyst). Enzyme can be used to replace partly or complete the chemicals used in tannery processes. Recently, micro-organisms are considered a appropriate device to produce enzymes. Furthermore, it is necessary to select potential micro-organisms for enzyme production.“Exolite”, that is first enzyme produced in pilot scale in Indonesia, proved to reduce significantly pollutant in waste of leather tannery industries. Therefore, the development of enzyme industry in Indonesia is needed to be supported.

Abstract

Soybean is the one of the most important food commodities after rice and maize. It is considered as significantprotein sources and is also used as raw material for several foods and feeds industries. The availabilityof soybean is mostly fulfilled from import, namely around 60% or 1.2 million ton/year. Therefore, the increaseof soybean productivity is an opportunity that should to be executed for minimizing the dependency of importedproduct. The development of soybean productivity for self supporting is very reasonable. The potencies, such as thetechnologies readiness (tolerant superior varieties and bio-fertilizer) and farming technology, are considered assuccess factors for supporting the increase of soybean productivities in sub-optimal lands. Meanwhile, the potencyof sub-optimal land for agriculture is still large quantity, namely 30.67 million hectares. The successful requiresthe supports of government policies and their commitments as well as the participation of farmer communities.

Abstract

Mangrove fungi are known as sources of biological active compounds. The study and the report of secondary metabolites of mangrove fungi as insecticides is very limited in Indonesia. This study assess the insecticidal activities of ethyl acetate extract of Indonesian mangrove fungus Emericella nidulans BPPTCC 6038 against Spodoptera litura (Lepidoptera, Noctuidae) neonate larvae and pupae. The fungus E. nidulans BPPTCC 6038 was isolated from leaves of mangrove Rhizophora mucronata and identified based on ITS rDNA sequence data, with the GenBank accession number KP165435, and confirmed with morphological observation. This fungus strain was grown on malt extract broth for 14 days on rotary shaker at 65 rpm, and incubated at room temperature. Mortalities of S. litura were observed on larvae fed on artificial diet containing ethyl acetate extract of E. nidulans at concentrations of 625 – 5000 ppm. The lethal concentration of the extract which causes 50% mortality of larvae (LC50 value) was 1102.27 ppm. The other effects of fungus extract on S. litura were decrease in growth rate, longer larval period, inhibition on pupal development and absence in adult emergence. The HPLC analysis of extract showed that the crude extract contained three major compounds. This study provides evidence that the extract of E. nidulans possesses insecticidal activities against S. litura.

Abstract

Dalam rangka ketahanan dan kemandirian pangan di Indonesia, maka diperlukan upaya peningkatan produktivitas pertanian, khususnya untuk tanaman pangan. Upaya intensifikasi selama ini dinilai berhasil, namun produktivitas sudah mendekati keadaan jenuh, sehingga upaya ekstensifikasi dengan memanfaatkan lahan marginal merupakan alternatif yang harus segera dilakukan. Indonesia sangat berpotensi mengembangkan pertanian di lahan marginal untuk peningkatan produktivitas tanaman pangan, mengingat luasan lahan yang dimiliki lebih dari 30 juta hektar dan memiliki kesiapan teknologi budidaya melalui aplikasi bioteknologi. Pemanfaatan lahan marginal untuk peningkatan produktivitas pangan masih banyak menghadapi kendala teknis sehingga dibutuhkan investasi yang lebih mahal. Disamping itu, implementasi pemanfaatan lahan perlu memperhatikan berbagai kearifan lokal sedemikian rupa agar berbagai sumber daya dapat dimanfaatkan secara optimal. Riset di bidang bioteknologi sudah banyak dilakukan di Indonesia dan hasil-hasilnya sangat berpotensi untuk peningkatan produksi tanaman pangan di lahan marginal. Hasil-hasil riset tersebut antara lain adalah varietas tanaman hasil rakitan yang toleran pada lahan marginal, pupuk hayati dan agen pengendalian hama. Selain itu, keberhasilan program peningkatan produktivitas pangan di lahan marginal perlu dukungan kebijakan dan komitmen pemerintah, baik pusat dan daerah serta dukungan masyarakat petani. In the framework of food security and food self-sufficiency, the improvement ofagricultural product of staple food commodities is urgently required. Intensification program is considered to be successful, but the productivity has recently been relatively saturated. Hence, the extensification program by using the marginal or sub-optimal land is an important option to be executed immediately. Indonesia has a great potential to develop agriculture in the sub-optimal land for increasing food production because it has a vast area of land of more that 30 million hectares and the readiness of farming technologies, specifically the application of biotechnology. The use of sub-optimal land for the improvement of food productivity is still facing several constraints, so that the more expensive capital investment is needed. In addition, the local wisdoms should be seriously considered in order to optimize the use of resources. Biotechnology researches have been done in Indonesia, and their results are potentially useful for improving the food productivity in sub-optimal lands. Theresearch results consist of the engineered plant varieties which are tolerant to sub-optimalland, bio-fertilizer and bio-pesticide. Moreover, the success of the program requires the support from the government (centraland regional), as well as the farmers communities.

Abstract

Program swasembada kedelai telah berlangsung lebih dari dua dekade, namun sampai dengan tahun 2014, belum dapat diwujudkan. Berbagai permasalahan mendasar belum dapat diselesaikan, sehingga produksi kedelai justru cenderung menurun dan impor terus meningkat. Penelitian dan pengembangan kedelai sudah banyak dilakukan dan telah menghasilkan teknologi dan produk teknologi yang berpotensi untuk mendukung peningkatan produksi kedelai. Teknologi dan produk teknologi yang dimaksud utamanya adalah benih unggul dan pupuk hayati. Sejumlah benih unggul (sekitar 25 varietas) berpotensi untuk produksi kedelai dengan produktivitas lebih dari 2,5 ton per hektar, dan mempunyai sifat toleran terhadap berbagai cekaman di lahan sub-optimal dan akibat perubahan iklim. Demikian pula berbagai jenis pupuk hayati dan pupuk organik yang secara khusus diperuntukkan untuk peningkatan produksi kedelai di berbagai jenis lahan sub-optimal. Namun kenyataan di lapangan teknologi dan produk teknologi tersebut baru sedikit yang dapat diimplementasikan di tingkat petani dan digunakan untuk produksi komersial. Oleh karena itu, diperlukan akselerasi implementasi hasil litbang melalui media intermediasi yang dapat memfasilitasi terciptanya jalinan komunikasi, kerjasama antar pihak-pihak terkait, yaitu peneliti, petani, mitra usaha dan pemerintah untuk bersinergi dalam upaya peningkatan produksi kedelai dan swasemda kedelai. Pola budidaya kedelai ke depan perlu diarahkan pada pola budidaya yang ekonomis dan maju yang antara lain menerapkan model “estate crop” di lahan sub-optimal yang didukung dengan mekanisasi yang memadai.Soybean self-supporting programs have been carried out for more than two decades, however, they were just realized in 2014. A number of basic constraints (such as functional shift of soybean field, and availability of superiority of soybean seeds) have not been overcome, so that the soybean production tends to decline and the soybean import tends to increase. A lot of research and development programs have been done and have resulted in potential technologies and technological products, which are potencially increasing soybean productivity. The technologies and technological products are mainly superior soybean seeds and biofertilizers. A number of superior soybean seeds (about 25 varieties) are potential to produce more than 2.5 ton per hectar, and are tolerant vis a vis to many types of stresses in sub-optimal land and climate changes. Several biofertilizers and organic ferlilizers are also specially used for soybean plant productivity in sub-optimal land. In fact, the technologies and technological product are still limited to be implemented by soybean farmers and to be used in commercial production. Consequently, the implementation of research and development needs to be accelerated by intermediation which could facilitate networking, communication and collaboration among stakeholders (researchers, farmers, enterpreneurs and government) for sinergizing in increasing soybean productivity and soybean selfsupporting. Further, the soybean farming should be done to economic farming model in form of “estate crop” in sub-optimal land and supported by appropriate mechanization.

Abstract

Konsumsi beras yang tinggi berakibat rapuhnya ketahanan pangan. Tingginya konsumsi beras ini ditunjukkan oleh skor Pola Pangan Harapan (PPH) pada kelompok padi-padian yang jauh lebih tinggi dari skor ideal yaitu 62,2 persen dari 50 persen skor ideal. Disisi lain, Indonesia kaya akan produk pangan lokal berbasis karbohidrat (singkong, ubi jalar, talas, dan sebagainya) yang berpotensi untuk substitusi beras. Oleh karena itu, program penganekaragaman pangan berbasis pangan lokal dinilai sebagai solusi yang tepat untuk mengurangi ketergantungan pada konsumsi beras. Penganekaragaman pangan pada perpektif yang lebih luas, tidak hanya untuk konsumsi pangan berbasis karbohidrat, tetapi juga untuk pangan berbasis protein dan lemak untuk mencapai pola pangan seimbang. Penganekaragaman pangan ternyata juga mempunyai dampak positif ikutan oleh terjadinya kompensasi zat gizi dari keragaman pangan tersebut yang dapat meningkatkan nilai biologis pangan yang dikonsumsi dalam metabolisme dan sekaligus berkontribusi untuk kesehatan tubuh. Untuk mendukung keberhasilan program penganekaragaman pangan, maka berbagai revitalisasi pelaksanaan program perlu dilakukan, yaitu melalui: (i) penyusunan rencana induk dan program secara holistik; (ii) pengembangan produk olahan berbasis pada iptek dan inovasi; (iii) pengembangan agroindustri dan agrobisnis berbasis pada produk pangan lokal; (iv) diseminasi dan sosialisasi; dan (v) dukungan kebijakan anggaran yang memadai untuk pelaksanaan kebijakan yang telah ditetapkan.The highest consumption of rice causes the weakness of food security. The highest consumption office is indicated by high score offood pattern expectation ofpaddies group consumption, which is much higher from ideal score, namely 62.2 per cent from ideal score of 50 per cent. On the other side, Indonesia is rich in carbohydrate-based local-food products (cassava, sweet potato, taro, etc), which are potentially used for rice substitution. Therefore, the programs of food diversification based on local-food products are considered as appropriate solution for minimizing the dependency of rice consumption. In wider perspective of food diversification, it should be not only implemented for diversification of carbohydratebased food, but should also include for the diversification for protein-based food and fat-based food for obtaining a food pattern balance. In fact, food diversification also possesses additional positive effect due to the compensation of nutrition content from the food diversification, which can increase the biological value of consumed foods in the metabolism and at once contribute to body health. For supporting the successful food diversification program, therefore it is required a revitalization on the implementation program, through: (i) preparation of holistic program master plan, (ii) science, technology and innovation based products development, (Hi) establishment of agro-industry and agro-business based on the local food products, (iv) dissemination and socialization, and (v) support of appropriate budget policy for implementation of the decided policies.

Abstract

Kedelai adalah komoditas pangan penting di Indonesia. Kedelai merupakan makanan bergizi yang sudah berabad-abad lamanya dan telah menjadi bagian budaya bangsa. Bentuk makanan yang umum dikonsumsi terutama adalah tempe, tahu, kecap dan tauco. Namun demikian, Indonesia sejak tahun 1974 tidak dapat memenuhi semua kebutuhan secara mandiri, dan akibatnya Indonesia menjadi negara pengimpor kedelai sampai sekarang. Kecuali pada tahun 1992, tercatat produksi kedelai nasional mencapai 1,9 juta ton sehingga pada tahun tersebut dikatakan mampu berswasembada. Ketergantungan impor kedelai meningkat dari tahun ke tahun dan pada tahun 2012 mencapai 70 persen. Oleh karena itu, pemanfaatan bioteknologi diharapkan dapat menjadi solusi untuk mendukung program swasembada dan ketahanan pangan kedelai, yaitu mencakup aspek peningkatkan produksi kedelai (varietas unggul dan pupuk hayati), dan melalui perbaikan aspek konsumsi (proses fermentasi) yang dapat memperbaiki kualitas gizi dan keamanan konsumsi. Oleh karena itu, keberhasilan implementasi bioteknologi untuk ketahanan pangan kedelai diperlukan suatu model sistem inovasi yang melibatkan berbagai pihak seperti peneliti, petani, penyuluh, investor dan industri.Soybean is an important food commodity in Indonesia. Soybean is considered as a nutritious food, which is consumed for the centuries and to be part of national culture. Generally, the types of food products from soybean are tempe, tofu, soy-sauce (kecap) and taucho. Unfortunately, since 1974, Indonesia could not fulfill the demand trough domestic production, and consequently Indonesia has been an importing country of soybean up to present. Except in 1992, it was noted that the national soybean production reached 1, 9 million tons, so in this year it called to be able to self sufficiency. The import dependency increased gradually from year to year, and in 2012 the level reached nearly to 70 percent. For this reason, the implementation of biotechnology is expected to be a solution for soybean self supporting program and soybean food security. The implementation covered two aspects namely: increasing the soybean production (superior variety and biofertilizer), and improving on consumption (fermentation process), that is able to increase on nutritive value and food safety. Therefore, the successful of the implementation of biotechnology on soybean food security needs an innovation system model involving related stakeholders such as researcher, farmer, agricultural extension, investor and industry.
