Abstract

Improving of water quality from siak river that have been used for long time by communities around the river for many purposes such as drinking water and washing has been done by implementing various method such as filtration, coagulation, aeration absorption. Each method has specific characteristic and advantages. Filtration with sand and gravels can decrease concentration of total suspended solid, Fe, Mn and organic material (KMnO4). Coagulation with alum (Al2SO4) can decrease TSS Concentration, Fe, Mn, NO3, NO2, KMnO4, coliform and coli fecal. Furthermore, aeration with a oxygen can decrease TSS concentration, TDS, Fe and Mn. While absorption whit active carbon can decrease concentration of TSS, Mn and Fe. After the four methods had been studied, the best result was obtained through combination of four methods (filtration, coagulation, aeration and absorption).

Abstract

Most of the Kampung Harapan residents are farmers, namely farming corn, sweet potatoes, chilli, fruit, vegetables (such as spinach and kale) and fish farming. This village is prospective to be used as rearing sites for aquaponic systems. Aquaponic cultivation technology can be developed in limited area and water, and it also can increase business efficiency through the utilization of nutrients from the uneaten fish meal and the metabolism wastes of fish for vegetables, so it could be able to produce fish and vegetables optimally on narrow land and limited water sources, including in urban areas. Through the fish rearing with aquaponic systems, fish farmers will get two advantages in one production stage. This activity was carried out through discussion and practice, which the activity took place in the village office and in the home yard of the fish farmer group in Harapan Village. Extension activities involve fish farmers, plantation farmers and several students. The results of the activities showed that skills and knowledge of fish farmers increase regarding aquaponics fish farming and making pellets mix with gingger. Plastic fish ponds as a pilot project produce high yields of catfish and leafy vegetables, so it can be an alternative income for fish farmers.

Abstract

Koto Pangean village has an area of 15 ha, the topography of the area is flat and hilly land with a high of 300 m up to from marine water surface. Type of soil type is black on the top layer and yellow on the bottom layer. Width of the waters of Koto Pangean Village is 2,003.25 ha, has been used for fisheries activities ranging from 2.50 ha in lakes, 1.8 ha swamps, rivers of 180 ha and 10 ha for a fishpond. Several kinds of fish are reared in this village such as African catfish (Clarias batrachus), tilapia (Oreochromis niloticus) and carp (Cyprinus carpio). The main problems faced by fish farmers in this village are: the occurrence of fish deaths caused by decreasing of water quality, accumulation of organic matter, the number of fish attacked by disease and increasing number of pathogenic microorganisms that attack fish, and high commercial fishmeal prices which results in high operational costs for fish farming. To overcome these problems, knowledge innovations are carried out to farmer groups by conducting counselling about; 1. the use of probiotics to improve the soil quality and pond water, 2. Method to prevent fish from disease attacks, 3. how to make pellets by utilizing local ingredients of good quality. The results of the activities that have been carried out show that there is an increase in knowledge and skills of fish farmers, especially being able to increase catfish production with probiotic technology and decreasing operational costs for providing fish meal as a result of the increasing the income and welfare of fish farmer groups.

Abstract

The livelihoods of the people of Tangkerang Utara Village are; in agriculture, plantation, animal husbandry, self-employment and fisheries. In the fisheries sector, there are two groups of fish cultivators (POKDAKAN) in this kelurahan, namely; POKDAKAN Cahaya Utara Mandiri and Dolphin Farm, which conduct fish farming in soil and cement ponds and cages. The main problems faced by POKDAKAN are the limited availability of water intended for fish cultivation and the wate rquality that is not suitable for catfish growth. Throught his program of guided villages, knowledge and technology is given on the technique of applying probiotics to cultivation media to improve wate rquality and minimize water use. The method used in the community service activities of the Assisted Village is the method of lecturing, discussion and direct practice in the pools owned by POKDAKAN members. The results of the evaluation of 23 extension participants showed that 20 people (86.96%) had never known about the application of probiotics in cultivation media, while 2 people (8.70%) had known about the application of probiotics and 1 person (4.34%) had apply it to catfish farming ponds. After participating in this training activity, there was an increase in knowledge about the application of this probiotic by 69.57%. Meanwhile, 22 participants understood the dosage and frequency of feeding, and all participants had already known the criteria for healthy fish seeds. The partners' assessments of the implementation of this activity are: 52.17 strongly agree that this probiotic application can be done independently; 52.17% strongly agree that probiotic applications can improve water quality; 60.87% strongly agreed that it could be an alternative livelihood; 65.22% strongly agree to speed up the maintenance period.

Abstract

Chicken manure is an organic material that is abundant in Mentangor Village which has been used as fertilizer when fertilizing ponds, however the continuous use of fertilizers can reduce the quality of the bottom soil and pond water. One of the technological innovations to improve the quality of chicken manure is fermentation using EM4 to produce bokashi fertilizer. Bokashi fertilizer can increase the abundance of phytoplankton and zooplankton which are useful as natural fish food so that they can reduce the use of artificial feed, which in turn can reduce the operational costs of fish farming. Community service activities are carried out for the purpose of innovating knowledge and skills of fish farmers regarding techniques for making bokashi fertilizer from chicken manure and techniques for making fish feed in the form of pellets to increase cultivated fish production. This activity is carried out by lecturing, discussion and practice methods, which involve fish cultivator groups and Kukerta students. The results of community service activities show the high enthusiasm of farmers towards the activities carried out, resulting in increased knowledge, insight and skills of farmer groups. Thus, fish farming activities can be carried out by farmers by reducing operational costs for pond management and provision of feed so as to produce high fish production and increase the income and welfare of farmer groups.

Abstract

The main problem faced by catfish farmers in North Tangkerang Village is that the market of catfish is only in fresh form, so that when the catfish harvesting activities is abundant, the price of fish decreases. The solution to overcome this was by conducting training activities for the PKK group of North Tangkerang Village, about the processing techniques of catfish cultured products into crackers and catfish nuggets. This service activity goes through three stages in the form of lectures on processed fish product innovations, processed product manufacturing practices, process evaluation and knowledge improvement evaluation. The results of the evaluation of the process and increasing knowledge of the implementation of the training activities carried out showed that during practice all extension participants were directly involved at each stage carried out and seemed enthusiastic in following each stage of the activities. After the training activities, all participants were able to independently make the technique of making catfish crackers and nuggets. Increased knowledge and skills of training participants by 81%. In general (79%) strongly agree with the implementation of this activity and 21% agree. The impact of this activity is expected to be an alternative source of income for the PKK group in this village and can continue in the future because of the assistance in the form of equipment for the processed production from the UNRI LPPM ABDIMAS TEAM.
