Abstract

Lecturer and community based science and technology activities (IbDM) were carried out with the aim of disseminating technology for Gurame culture intensively in an effort to increase fisheries productivity in Limau Manis, Pauh Subdistrict, Padang City and increase the knowledge and skills of fish farmers (community) in Koto Tangah Village in the field of Gurame fish maintenance business in West Sumatra, so that they are expected to be able to carry out maintenance in a good / environmentally friendly manner. Besides this IbDM activities are also expected to be able to reduce operational costs in maintaining Nirwana Tilapia and in the end can increase the income of the farmers (community) of Limau Manis Village through the development of sustainable fish farming. To achieve optimal technology dissemination results, the main target of IbDM in Pauh Subdistrict is fish farmer groups and community leaders / leaders of Limau Manis Village who are expected to be able to motivate farmers to socialize the method of making alternative formula feeds for intensive development of Nirwana Tilapia aquaculture and environmentally friendly. The methods used in this activity are (1) counseling, with the main material: (a) providing knowledge of various kinds of raw materials that can be used for fish food, (b) providing knowledge about the preparation of artificial food formulas / compositions, ( c) provide knowledge about the process of making artificial food (d) increase public knowledge about how to store pellets that are good to be more durable and (e) provision of material on testing the quality of feed, both physically, chemically and biologically; and (2) Intensive demonstration of making alternative pellet feeds for Nirwana Tilapia aquaculture. From the results of the IbDM activity, it was found that the knowledge and skills of farmer groups in Limau Manis Sub-district, Kec. Pauh, Padang before the IbDM activities were carried out was still very low. However, the motivation or desire of the community of IbDM partner farmer groups to carry out the culture or maintenance of fish is very large. This can be seen from the desire of the IbDM partner farmer group to master the technology of making fish feed from the results of leaf waste and taro stems which are processed into flour relatively high. Furthermore, the results of IbDM activities in the community can increase the knowledge and skills of the community in finding alternative feed for fish feed so that culture activities can run well in IbDM partner areas. In order for aquaculture to run well in partner areas of IbDM, it is necessary to carry out IbDM activities continuously on the techniques of making alternative fish pellets and efficient and effective fish-raising techniques. Besides that, it needs financial support or credit by the authorities to the community or fish farmers for capital to develop their businesses.

Abstract

Kegiatan IPTEKS berbasis dosen & masyarakat (IbDM) ini dilakukan dengan tujuan untuk diseminasi teknologi budidaya ikan Nila Nirwana secara intensif dalam upaya meningkatkan produktivitas perikanan di Kelurahan Limau Manis, Kecamatan Pauh, Kota Padang dan meningkatkan pengetahuan serta keterampilan petani ikan (masyarakat) Kelurahan Koto Tangah dalam bidang usaha pemeliharaan ikan Nila Nirwana di Sumatera Barat, sehingga diharapkan mereka dapat melakukan pemeliharaan dengan cara/teknik yang baik dan ramah lingkungan. Selain itu kegiatan IbDM ini juga diharapakan mampu mengurangi biaya operasional dalam pemeliharaan ikan Nila Nirwana dan pada akhirnya dapat meningkatkan pendapatan para petani (masyarakat) Kelurahan Limau Manis melalui pengembangan usaha budidaya ikan yang berkelanjutan. Untuk mencapai hasil diseminasi teknologi yang optimal maka sasaran utama IbDM di Kecamatan Pauh ini adalah kelompok tani ikan dan para pembina/pemuka masyarakat Kelurahan Limau Manis yang diharapkan mampu memberikan motivasi kepada petani untuk mensosialisasikan metoda pembuatan pakan formula alternatif untuk pengembangan budidaya ikan Nila Nirwana secara intensif dan ramah lingkungan. Metoda yang digunakan dalam kegiatan ini adalah (1) Penyuluhan (ceramah), dengan materi utama : (a) memberikan pengetahuan tentang berbagai macam bahan baku yang dapat dimanfaatkan untuk makanan ikan, (b) memberikan pengetahuan tentang penyusunan formula/komposisi makanan buatan, (c) memberikan pengetahuan tentang proses pembuatan makanan buatan (d) menambah pengetahuan masyarakat tentang cara menyimpan pelet yang baik agar lebih tahan lama dan (e) pemberian materi tentang pengujian mutu pakan, baik secara fisika, kimia dan biologis; dan (2) Peragaan pembuatan pakan pelet alternatif untuk budidaya ikan Nila Nirwana secara intensif. Dari hasil kegiatan IbDM ini didapatkan bahwa pengetahuan dan keterampilan kelompok tani Kelurahan Limau Manis Kec. Pauh, Padang sebelum dilaksanakan kegiatan IbDM ini masih sangat rendah. Namun demikian motivasi atau keinginan masyarakat kelompok tani mitra IbDM untuk melakukan usaha budidaya atau pemeliharaan ikan sangat besar. Hal ini terlihat dari keinginan masyarakat kelompok tani mitra IbDM untuk menguasai teknologi pembuatan pakan ikan dari hasil limbah daun dan batang talas yang diproses menjadi tepung relatif cukup tinggi. Lebih jauh dari hasil kegiatan IbDM pada masyarakat ini dapat menambah pengetahuan dan keterampilan masyarakat dalam mencari pakan alternatif untuk pakan ikan sehingga kegiatan budidaya dapat berjalan dengan baik di daerah mitra IbDM. Agar kegiatan budidaya berjalan dengan baik di daerah mitra IbDM perlu dilakukan kegiatan IbDM secara berkelanjutan tentang teknik pembuatan pelet ikan alternatif dan teknik pemeliharaan ikan yang efisien dan efektif. Disamping itu perlu dukungan dana atau pemberian kredit oleh pihak yang berwenang kepada masyarakat atau petani ikan untuk modal pengembangan usahanya.

Abstract

Currently, seaweed extracts are widely used as plant biostimulants to increase the efficiency of nutrient use, tolerance of abiotic stress, and improve plant quality. In this study, tested the effect of different Padina minor seaweed extract formulas (liquid extract and powder extract) and the frequency of application of Padina minor seaweed extract (b0 = control; b1 = 1 x application; b2 = 2 x application; and b3 = 3 x application) as a biostimulant to the growth of upland rice. From the results of the study, it was found that there was no significant effect of the application of the two extract formulas and the frequency of application, but the administration of Padina minor extract 3 times during vegetative growth increased all growth parameters, such as: plant height, number of tillers, fresh and dry weight of plants, and chlorophyll content. It was concluded that giving Padina minor extract 3 times could increase the vegetative growth of upland rice effectively.
