Effect 17α-Metiltestosterone Hormone with Different Dosage to Percentage Male Sex, Absolute Weigh Growth, and Survival to Congo Tetra Fish (Micraleptus interruptus)

Congo Tetra fish is one of the freshwater ornamental fish species which is in great demand because of its high economic value. Male congo tetra fish have a higher selling value than female fish, because the morphology of their bodies looks more attractive, especially their brighter colors and long fins. Sex reversal technology is one technique that can be used to obtain male monosexual offspring.The hormone 17α-methyltestosterone in male fish can increase spermatogenesis and determine secondary sex markers in male fish through the formation of sexual characteristics in fish morphology and body color. The administration of the hormone 17α-methyltestosterone with the right dose can increase the percentage of male sex of Congo Tetra fish. The purpose of this study was to determine the effect of the hormone 17α-methyltestosterone with different doses on the percentage of male sex, absolute weight growth, and survival of congo tetra fish, to determine which 17α-methyltestosterone hormone dose had the best effect on the percentage of male sex, growth in absolute weight, and survival in congo tetra fish. This research was conducted at the Regional Technical Service Unit of the Fish Seed Center for Ternate City. The time for conducting the research starts from March to May, 2020. In this study, 4 treatment doses of hormones were used, each treatment was repeated 3 times. The treatments tried were as follows: Treatment A: Dose 2 mg/l, Treatment B: Dose 3 mg/l, Treatment C: Dose 4 mg/l, Treatment D: Dose 0 mg/l (control).The results showed that the hormone 17α-methyl testosterone with different doses had a very significant effect on the male sex percentage of congo tetra fish, but it was not significantly different on the growth in absolute weight and survival of congo tetra fish. The highest average percentage of male sex in congo tetra fish was found in treatment C (dose 4 mg/l) which was 86.6%, the highest average value of growth in absolute weight was found in treatment A (hormone dose 2 mg/l) of 1.083 g, and the highest survival was found in treatment D (control) of 90.473%.

As one of fish commodity, Catfish (Pangasius pangasius) has a very important economic value for the community. The time needed for catfish cultivation tends to be long and the price of feed is high so that it triggers the less optimal production of catfish. One way to maximize good production and with minimized time is by adding multivitamin probiotics to the feed. This research aims to analyze the optimal dose of probiotics to the growth and survival rate of catfish . Method used is Complete Randomized Design Design (CRDD) using 4 treatments of probiotic doses and 3 replicates. The treatments are A Control (0.00 ml/kg), B (10 ml/kg), C (15 ml/kg), and D (20 ml/kg). Absolute weight, absolute length, and survival of catfish are the main variables observed. The data were analyzed by using the analysis of variance and continued with the LSD test (the Least Significant Difference), Ü = 0.05. The optimal dose of probiotics based on the absolute length and absolute weight of catfish is 10 ml/kg and it produces an absolute weight of 5.27 gram and absolute length of 5.76 cm. The optimal daily specific growth rate is at the probiotics dose of 10 ml/kg which is 2.302.55%/day. The highest survival rate for catfish is 100% at probiotic doses of 0.000 ml/kg, 10 ml/kg and 15 ml/kg. The range of water quality is in the temperature of 27.5 – 28,90C, pH 6.79 - 7.88, DO 6.4 - 7.9 ppm, and ammonia 0 ppm.

Based on the concept of a livable and global age-friendly city, pavements are a public facility that the city should provide to the people. Appropriate pavements will be beneficial for the people, particularly for good quality of life for the elderly to move around in the city. This study explored the behaviour of the elderly in the use of pavements and the problems confronted. The study also evaluated the value of the pavement walking area as it reflected the benefits of pavements to the elderly by applying the Contingent Valuation Method (CVM). During March-May 2017, data were collected using interviews with 601 elderly living in Bangkok. The study indicated that the main problem for senior citizens regarding their use of pavements was from being disturbed by motorbikes riding on the pavements. The average value of pavement for the elderly was about THB 160 (USD 5.30) per person per year. Thus, the benefits of pavements to the elderly in Bangkok was approximately THB 158 million (USD 5.2 million) per year. Thus, policy makers should make proper budget allocations for elderly-friendly pavement management and seriously address the problems confronting the elderly in using pavements, to maximize the usefulness of pavements not only for the elderly but also for the public and to support a sustainable urban development.
