Abstract

The application of lime is attempt to increase the pH of the soil and pond water for catfish culture in swamps which generally have low pH. Liming is not only affected by soil and water pH, but also the content of soil organic carbon. The purpose of this study was to determine the dose of blood cockle shell lime on the bottom soil of the pond in increasing the pH of the water culture medium as well as the survival and growth of catfish. This study used a completely randomized design (CRD) with 6 treatments and 3 replications.The treatments given were differences in the dosage of cockle shells lime, consisting of 6,000 kg ha-1 equivalent to CaO (P1), 8,000 kg ha-1 equivalent to CaO (P2), 10,000 kg ha-1 equivalent to CaO (P3), 12,000 kg ha-1 equivalent to CaO (P4), 14,000 kg ha1 equivalent to CaO (P5), and 16,000 kg ha-1 equivalent to CaO (P6). The results of this study indicate that P6 with a dose of 16, 000 kg ha-1 equivalent to CaO increased the initial soil pH from 3.2 to 7.8. As for water pH, the best dose is P3 treatment with a dose of 10,000 kg ha-1 equivalent to CaO which increases the initial pH from 3.40 to 6.97 and produces 100% survival of catfish, an absolute length of growth 5.52 cm and absolute of weight growth 11.15 g with feed efficiency of 97.14%.

Abstract

Naturally, during dry season, pyrite tent to be oxidized due to soil water content and groundwater level decrease. This paper aims to evaluate the influence of soil water condition and ameliorants on pyritic soil pH dynamics. Pyritic soil was taken from a depth of 70-90 cm below soil surface in the acid sulphate land located at Mulyasari Village, Tanjung Lago District, Banyuasin Regency, South Sumatra. The research was carried out in greenhouse with 2 treatment factors, namely: Water condition (K1 = water condition maintained at 5 cm above soil surface during incubation period and K2 = water condition at 5 cm above soil surface and allowed to decrease during incubation period) and ameliorant (T = Without Ameliorant, B = Organic Matter, D = Dolomite, P = Phosphate Fertilizer and S = Silicate Coal Ash). The results showed that pyritic soil pH tended to be stable during incubation period for K1 treatment, and pH of soil treated with dolomite > Silicate Coal Ash > Organic Matter > P Fertilizer > Without Ameliorant. Meanwhile for K2 treatment, soil pH tended to decrease with the highest rates are 21.58x10-2, 19.33x10-2, 4.38x10-2, 7.50x10-2, and 12.07x10-2 pH unit per day, respectively for without ameliorant, organic matter, dolomite, phosphate fertilizer and silicate coal ash. The highest rate of decrease in pH of pyritic soil occurred in the range of decreasing water content from 66.31 to 41.73% for without ameliorant, organic matter and phosphate fertilizer, from 41.73 to 13.93% for silicate coal ash, and from 13 .93 to 8.22 % for dolomite. These findings can be applied for managing pyritic soil by maintaining soil water content from falling under water content critical limit range and under uncontrolled dry conditions it is recommended to use lime to minimize pyrite oxidation.

Abstract

Silk worms is commonly used as natural feed for larval on fish hatchery. Cultivating silk worms requires a substrate as well as a feed source to support their growth. Fermented quail manure, tofu waste, and tapioca flour can be utilized as cultivation media for silk worms. This activity aims to apply the use of fermented quail manure, and tofu dreg, and tapioca flour on the growth of silk worms at Unit Pembenihan Rakyat D5 Suka Pindah Village, Ogan Ilir, South Sumatera. This activity is community service through extension and silk worm culture using media from fermented quail manure and tofu dregs. Silk worm cultivation was carried out using a closed-flow water system with two containers, one for fermented media and one for non-fermented media. Silk worms 150 g m-3 were stocked and reared for 30 days. The results obtained from community extension are an increase in understanding of the target audience from quite good to good and very good. The result of the silk worm culture demonstration plot show that absolute biomass growth in the fermented media at 588.80 g m-2 compared to non-fermented media at 440.00 g m-2 Therefore, fish farmers can apply silk worm culture with fermented media to be able to provide natural feed of fish, independently.
