Abstract

The purpose of this study was to determine the internal and external factors of sago agro-industry development and to identify the strategy for developing sago agro-industry in Asaki Village, Lambuya District, Konawe Regency. The determination of the location of this study was carried out purposively, which is a method of determining the research area intentionally. The population in this study were all farmers who were in the sago agro-industry in Asaki Village, Lambuya District, Konawe Regency, where the number was 36 people. The sample determination was carried out by census, namely by taking all populations as research samples. The analysis used the SWOT formula. The results of the study Internal factors are strength factors consisting of seven, namely: quality products at affordable prices, strategic production locations, experience in business, having their own sago plantation land, products without preservatives and bleach, accepting orders in advance. Weakness factors consist of five, namely: small production results, no regular consumers, production is carried out with traditional equipment, lack of supporting facilities, only relying on the capital of the business owner. External factors are opportunity factors consisting of six opportunity factors, namely: high consumer purchasing power, high demand for sago products, it is a staple food for the community, raw materials are easy to obtain, the availability of raw materials is guaranteed, more modern production machines have been created. Threat factors consist of five factors, namely: many competitors, no government assistance, increasing fuel prices, unstable raw material prices, changes in weather or climate and sago agroindustry is on the medium line or Hold and maintain strategy, which means that the processing business is maintained, maintained and improved where the Hold and maintain strategy is a profitable situation that has opportunities and strengths, so that it can take advantage of existing opportunities.

Abstract

ABSTRACT Eucaryote microbes have an important role in forming bioflocs in the brackishwater aquaculture ponds. Bioflocs become potential live feed for milkfish or crustacea. This study aimed to identify the potential of eukaryotic microbes in the brackishwater aquaculture as the biofloc candidates potential development. This study was done through the water quality assessment and potential indigenous microbes isolation approach. Sampling was retrieved from the water subcomposite and sediment on each intertidal inlet and outlet. The water quality of brackishwater pond and intertidal swamp tended to lack of nutrient as containing inoptimal dissolved oxygen, salinity, pH, and ammonia content for the milkfish culture. Therefore, liming and fertilizing should be done to enrich the indigenous microbes. Eucaryote microbe isolated from the enrichment media was the aquatic fungi (multicellular and unicellular fungi) and microalgae (bacillariophyta, chlorophyta, and cyanophyta). Fungi and yeast formed a floculation with microalgae. This form will become a biofloc candidate as a live feed and water quality controller for the development of brackishwater aquaculture in the swamp area. Keywords: eucaryote microbes, biofloc, aquaculture, pond, brackish water swamp ABSTRAK Mikrob eukariot berperan penting dalam pembentukan bioflok di tambak budidaya pada lahan rawa payau. Bioflok menjadi pakan alami untuk budidaya ikan bandeng atau udang. Tujuan riset ini adalah mengidentifikasi mikrob eukariot rawa payau potensial untuk pengembangan kandidat bioflok di akuakultur rawa payau. Riset ini dilakukan dengan pendekatan kualitas air serta isolasi mikrob indigenous tambak dan rawa pasang surut untuk mendapatkan isolat mikrob potensial sebagai kandidat pembentuk bioflok. Sampling dilakukan secara subkomposit pada air dan sedimen di setiap inlet dan outlet pasang surut. Kualitas air tambak dan rawa pasang surut menunjukkan kondisi oksigen terlarut, salinitas, pH, dan amonia berada di luar batas optimum budidaya ikan bandeng, sehingga perlu dilakukan pengapuran dan pemupukan untuk memperbanyak mikrob indigenous-nya. Isolasi mikrob eukariot dari media pengayaan diperoleh jenis fungi akuatik yang multiseluler dan uniseluler, sedangkan mikroalga yang diperoleh yaitu dari golongan Bacillariophyta, Chlorophyta, dan Cyanophyta. Fungi yang dapat membentuk hifa dapat merangkai mikroalga dan khamir untuk membentuk flok. Susunan ini diharapkan dapat menjadi bahan bioflok yang berguna sebagai pengendali kualitas air sekaligus pakan alami bagi pengembangan budidaya di lahan rawa payau. Kata kunci: mikrob eukariot, bioflok, budidaya, tambak, rawa payau
