Abstract

Berbagai upaya pemenuhan kebutuhan kedelai nasional, peningkatan produktivitas kedelai (Glycine max L. Merr.) dan peningkatan daya saing kedelai terus dilakukan pemerintah dan pihak-pihak terkait. Namun, peningkatan signifikan daripada produktivitas dan daya saing yang diharapkan belum juga terjadi sehingga target produksi nasional belum juga tercapai. Pulau Sulawesi memiliki potensi yang besar untuk menjadi sentra kedelai nasional sehingga berbagai persoalan harus mampu diselesaikan, baik pada tingkat on-farm maupun off-farm. Pemasukan teknologi pengelolaan kedelai yang efisien dan pendampingan petani menjadi bagian kunci penting dalam peningkatan produksi kedelai. Pelibatan semua stakeholder termasuk universitas akan menjadi solusi penting dan berkelanjutan bagi kelangsungan perkedelaian rakyat. Kegiatan ini dilakukan di Kabupaten Bone dengan melibatkan dua kelompok tani pada kecamatan Cina dan Barebbo dengan luas areal 10 ha. Periode penanaman September 2021 hingga Januari 2022. Teknologi tambahan yang diintroduksi adalah pupuk hayati mikrobat dan mikobiota. Introduksi pupuk hayati mikrobat dan mikobiota yang merupakan produk inovasi dari Fakultas Pertanian, Universitas Hasanuddin dan kegiatan pendampingan petani mampu menghasilkan produktivitas kedelai diatas 2 ton ha-1. Selain itu, perbedaan waktu aplikasi mempengaruhi produktivitas kedelai. Ketepatan dalam aplikasi dan  jenis pupuk hayati berperan dalam peningkatan produktivitas kedelai. Kata kunci: Kedelai, Pupuk hayati, Pendampingan petani.   ABSTRACT Efforts to fulfilment the national demand, boost productivity and increase the competitiveness of soybean are continuously conducted by the government and other stakeholders. However, significant improvements and competitiveness than expected have not yet occurred. Therefore, the target of national production has not been yet achieved. Sulawesi island has large potential to be one of the centres of national soybean production. Hence, several problems should be solved, both on-farm and off-farm levels. The introduction of efficient management technology to soybean plantations and farmers empowerment are important strategies in increasing soybean production. The involvement of other stakeholders, including universities and, academia will be a critical and sustainable solution for the sustainability of soybean. The programs were conducted in Bone regency involved two farmer groups with the number of area of 10 ha. The planting period was September 2021 until January 2022. Additional technology that was introduced was biofertilizer of Mikrobiota and Mikobiota. The biofertilizers are innovative products from the faculty of agriculture, Hasanuddin University. The introduction of the biofertilizer and farmers empowerment activities was able to reach productivity above 2 ton ha-1. In addition, the Time difference of application has influenced productivity. Correct time and biofertilizer play a significant role in increasing the productivity of soybean. Keywords: Snakehead fish, pinrang, stunting, surabi.

Abstract

A disease presumed to be caused by Fusarium was observed in cocoa open fields with few or without shade trees. Within the population of cocoa trees in the field, some trees had died, some had yellowing leaves and dieback, and the others were apparently healthy. In order to demonstrate Fusarium species as the causal pathogen and to obtain information concerning the incidence of the disease, its distribution and its impact on sustainability of cocoa, isolation of the pathogen, inoculation of cocoa seedlings with isolates and a survey of disease has been conducted. Fusarium was isolated from roots and branches, and inoculated onto cocoa seedlings (one month old) via soil. Symptoms appeared within 3-4 weeks after infection. These symptoms consisted of yellowing of leaves beginning from the bottom until the leaves falldown, and browning internal of vascular tissue. Darkened vascular traces in the petiole characteristic of vascularstreak dieback infection were absent. The occurrence of Fusarium in the field was characterized by the absence of obvious signs of fungal infestation on root of infected trees, yellowing of leaves on twigs, dieback, and tree mortality in severe infestations. Disease incidence could reach 77% and in this situation it was difficult for trees recover from heavy infections or to be regenerated in the farm. The study proves that Fusarium is a pathogen causing dieback and the disease is called as Fusarium vascular dieback (FVD). Its development is apparently enhanced by dry conditions in the field. Key words: Fusarium sp., vascular disease, dieback, FVD, Theobroma cacao L.
