Abstract

The partnership pattern is one of the choices of business patterns faced by boiler breeders. This study aimed to describe and analyze the factors influencing the breeders to decide to follow the partnership pattern, calculate and compare the income of broiler farming business through partnership and independent patterns and analyze the perceptions of broiler breeders on the pattern to be applied to the next business cycle. The method used in this research was a survey method and stratified random sampling. The results of the study showed that the factors of venture capital, skills, result marketing and risk of loss, the marketing factor of the results were the most significant factors affecting the decision of farmers to follow the partnership pattern. It was found that the partnership pattern provided an average profit of Rp. 40,138,384.88 higher than the independent business pattern which was only Rp. 33,029,505.00 in one production period. When viewed in terms of Return Cost Ratio (R/C), livestock business through a partnership pattern was 1.19, lower than the R/C independent livestock business with a value of 1.20. Meanwhile, for the Food Conversion Ratio (FCR), both partnership and independent livestock businesses had the same value, namely 1.26. When viewed from the performance index, the livestock business through the partnership pattern had an IP of 4.25 greater in value when compared to the independent business pattern which was only 4.19. The breeders following the partnership pattern tended to decide to continue to follow the partnership pattern even though they had sufficient capital and skills, afforded to market their products independently, and faced their own risks. Keywords: breeders perception, partnership pattern, determinants of decision makers

Abstract

Organic hydroponic cultivation systems require substitute nutrients other than inorganic fertilizers as a source of plant nutrients. Catfish cultivation waste is one of the potentials that can be used as hydroponic nutrients. This study aimed to find out the concentration of Liquid Organic Fertilizer (LOF) from fish cultivation waste as a substitute for commercial inorganic nutrients on the growth of pakcoy (Brassica rapa L.). This research was carried out in 2 stages, namely the manufacture of LOF from catfish culture waste and experiments using LOF as hydroponic nutrients. The results of this study showed that the increase in LOF nutrient content in anaerobic fermentation was higher than in aerobic fermentation. The use of LOF as a hydroponic nutrient, based on the parameters of plant height, number of leaves, SPAD value, root weight, crown weight, and dry weight obtained a smaller value that was significantly different compared to the inorganic nutrient treatment of AB mix. LOF concentration of 20%, both fermented aerobically and anaerobically, gave better growth when compared to higher concentration treatments. The nutrient content in LOF is difficult to adjust to the needs of hydroponic pakcoy, so that it will have a toxic impact on macro nutrients on the other hand, it also provides a response to micro nutrient deficiency.

Abstract

Pineapple peel waste can be used as liquid organic fertilizer (LOF) to add organic matter and improve soil quality for cultivating crops such as shallots. Shallots re vegetable crops that have great prospects for farmers because of the high demand for shallots that were not in accordance with their production. This study aimed to determine the effect of concentration and frequency of application of LOF of pineapple peel waste on the growth and yield of shallots. This research had conducted in farmer’s land in Perlang Village, Lubuk Besar District, Central Bangka Regency, from January to April 2021. This research used experimental method with a split plot design. The main plot is the concentration of LOF of pineapple peel waste which consists of 30 ml/l and 60 ml/l. Sub-plots are the frequency of application LOF of pineapple peel waste which consists of once in 7 days, once in 14 days, and once in 21 days. The results showed that the concentration of LOF of pineapple peel waste had no significant effect on all observed variables. The frequency of application LOF pineapple peel waste had a significant effect on the number of tillers per clump, but had no significant effect on the other variables. The interaction between the concentration and frequency LOF pineapple peel waste had no significant effect on the growth and yield of shallot plants. LOF application of pineapple peel waste with a concentration of 30 ml/l and a frequency of once every 7 days tends to be better for the growth and yield of shallot plants.
