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

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

Fish cultivators generally experience difficulties providing quality artificial feed (pellets) due to a lack of knowledge and skills in processing technology and making alternative feeds. Besides that, the costs incurred for feed procurement are relatively large, reaching 70 - 80% of the total production costs. However, the provision of feed is often an obstacle because, in addition to the increasingly high price, the quality of available feed does not always match the nutritional needs needed by Fish. The provision of quality feed for intensively cultivated tilapia dramatically affects the resulting growth and productivity. The higher the quality of the feed, the production will also increase. One of the technologies that can be applied to overcome this problem is the manufacture of alternative formulated diets using local raw materials. The method used in this service activity is the transfer of knowledge presented in the socialization activities in the form of 1) introduction to the types of alternative fish feed ingredients sourced from the area, (2) preparation of artificial tilapia feed formulations, (3) manufacturing technology artificial feed (pellets) and 4) monitoring and assistance. The socialization was carried out in the form of a lecture and was followed by a question and answer session. The results of farmer activities recognize the types of local feed that can be used as fish feed, know the preparation of feed formulations, and alternative artificial feed manufacturing technologies. The knowledge and skills possessed by fish cultivators are expected to overcome the difficulties of fish farmers in providing feed so that fish production and cultivation business increase.

Abstract

Kebutuhan masyarakat meliputi sandang, pangan dan papan. Kebutuhan sandang dan pangan tidak terlepas dari proses pembersihan dan pencucian. Salah satu bahan yang digunakan untuk proses pencucian adalah sabun. Sabun colek banyak digunakan untuk kebutuhan rumah tangga karena bentuk sabun yang lembek, tidak basah, tidak kering sehingga mempermudah penggunaannya, yaitu mudah ditakar dan mudah digunakan untuk bagian-bagian yang sulit pada pakaian berkerah dan lipatan lengan. Untuk itu sabun colek menjadi alternatif dalam pemilihan jenis sabun. Jika sabun colek ini dapat dibuat sendiri maka akan dapat menghemat pengeluaran keuangan dan akan menjadi peluang usaha untuk masyarakat dalam upaya meningkatkan kemampuan wirausaha dalam memproduksi sabun sendiri pada skala kecil dan menengah untuk dijual ke Pasaran. Kegiatan pembuatan sabun ini akan dapat menambah pengetahuan masyarakat tentang ilmu dan teknologi serta dapat menambah pengetahuan tentang kewirausahaan. Pengabdian ini direncanakan dilaksanakan pada kelurahan Pulau Payung kecamatan Rumbio Jaya Kabupaten Kampar. Kegiatan dilakukan dengan metode dalam bentuk penyuluhan yaitu mengenalkan cara pembuatan sabun colek dengan metode ceramah, diskusi dan melakukan demonstrasi/praktek pembuatan sabun colek. Kegiatan ini juga mendukung program pemerintah dalam meningkatkan kemampuan masyarakat dalam memproduksi barang kebutuhan sehari hari untuk menghemat pengeluaran masyarakat dan pada akhirnya dapat meningkatkan kesejahteraan masyarakat.
