Abstract

Kelabau (Osteochilus melanopleurus) is one of the local fish found in Borneo. Economically, kelabau fish has a reason to be cultivated because it has a fairly high price. One of the aspects that needs to be considered is the availability of raw materials. This study aimed to evaluate the use of fermented palm kernel meal in feed on feed conversion, growth, and survival of kelabau. The experimental design applied was a Completely randomized design (CRD) with 4 treatments and 3 replicates, namely (P0) no palm kernel meal added; (P2) palm kernel meal fermented for 0 hours, (P3) palm kernel meal fermentaded for 24 hours, and (P4) palm kernel meal fermented for 48 hours. Fish rearing was carried out for 40 days with feeding experimental frequency three times a day with at satiation. The  fish  was  kelabau  seeds measuring 4-5 cm and weighing 1-2 g. Ovserved variades tested in this study included feed conversion rasio , growth, and survival rate. The highest growth was resulted by  palm kernel meal fermented for 48 hours, the lowest feed conversion ratio (FCR) was resulted by falm kernel meal fermented 24 hours, and the survival of all treatment during this rearing werw 100%. However statisticaly no significant differences were observed in either/ grow or feed conversion ratio.  Kata kunci: Kelabau; EM4;  fermentasi; bungkil inti sawit

Abstract

The abandoned land of coal mining activity in a form of pond was used for fish culture by the people of Kutai Kartanegara Regency of East Kalimantan Province. However, the problem occurs firstly when the land opened for the open pit system that should make the change of water quality of physic, chemistry, and biology of pond after mining activity. This research was done to know the existing condition of former coal mining land, and to analyze the sustainability of aquaculture in this area. Aquaculture sustainability in former coal mining ponds were analyzing with multi dimensional scaling which is a developmental method of Rap-fish (rapid appraisal analysis). The results of the analyzing for every dimension showed that ecological, economical, and sociality has approved index, which mean that balanced were occurred in these dimension for sustainability of the aquaculture activity. The ecological dimension, economy, and social in the developing activity must be in balanced without domination to achieve for sustainability.

Abstract

Identification of the quality of void water after coal mining needs to be carried out in order to utilize the void as a place for fish farming. Identification of water quality, in the form of physical and chemical water. Physical and chemical parameters can influence the survival of cultivated biota, so research needs to be carried out to identify both physical and chemical water parameters related to aquaculture. The research method involves taking and measuring water samples in both in situ and ex situ settings. Measurements were carried out at three (3) sampling points, sampling four times. The parameters under observation include temperature, TSS (Total Suspended Solids), pH, brightness, dissolved oxygen (O2), biological oxygen demand (BOD), chemical oxygen demand (COD), nitrate (NO3), nitrite (NO2), ammonia (NH3), and hydrogen sulfide (H2S). A descriptive analysis of water quality is conducted, and the results are compared against the quality standards outlined in the Provincial Regulations of East Kalimantan, specifically, Number 2 of 2011, which pertains to Water Quality Management and Water Pollution Control (APPENDIX V, Class III). The results of the water quality analysis physically show that the temperature is 29.5 –31oC brightness 135 – 285 Cm, TSS 13.75 – 27.5 mg/L, Chemical pH 7.42 – 7.68, O2 4.26 – 4.84 mg/L, BOD 0.64 – 1.84 mg/ L, COD 2.96 – 5.93 mg/L, NO3 0.026 – 0.049 mg/L, NO2 0.002 – 0.006 mg/L, NH3 0.01 – 0.13 mg/L and H2S 0 – 0.0087 mg/ L. Both the physical and chemical water quality parameters conform to the standards established in the East Kalimantan Province Regional Regulation Number 2 of 2011, which focuses on Water Quality Management and Water Pollution Control. As a result, the post-coal mining void water's condition, in both physical and chemical aspects, remains suitable for aquaculture.
