Abstract

This study aims to identify the diversity of flies that were caught and interacted with carcasses at the day and night. Each of the three rat carcasses (Rattus norvegicus) was placed outdoor and indoor within the campus of IPB Dramaga. The carcasses were put into a screen cage. Observation of flies was begun at 06:00 am and so on every four hours until the skeletal stage of the carcasses reached. The flies that come to the carcasses and into the screen cage were collected and identified. The decomposition of the indoor carcasses is slower than at outdoor, with the longer fresh stage. Meanwhile, post-decay stage and skeletal stage were achieved at the same time at each location. Nine spesies captured flies which are forensic indicator were Chrysomya megacephala (Fabricius), Chrysomya bezziana Villeneuve, Chrysomya rufifacies (Macquart), Chrysomya saffranea, Chrysomya spp, Lucilia spp, Sarcophaga spp, Calliphora spp and Musca domestica. C. bezziana Villeneuve and C. megacephala (Fabricius) were the dominant flies at outdoor carcasses. Meanwhile, the indoor carcasses was dominated by Lucilia spp.

Abstract

Background: Jikumerasa waters are one of the waters that have ecological and economic value. The high level of human activity in utilizing marine waters in Jikurasa Village has the potential to cause pollution and reduce water quality. For this reason, it is necessary to measure the water quality of Jikuemerasa Village based on the conditions of physical, chemical and biological parameters.Methods: This research was conducted from September 2021 to October 2021. Sampling was carried out at seven stations. measurement of physical and chemical parameters directly (in situ), namely: temperature, brightness, pH and salinity. Water samples were taken to measure physical, chemical and biological parameters ex situ including: DO, BOD, COD and coliform bacteria in the laboratory.Results: The study showed that the parameters that were still in accordance with the quality standards at all research stations were: temperature, brightness, COD, BOD, Pb metal and the number of coliform bacteria. For the salinity parameter, only station IV has a salinity below the quality standard. In the DO parameter, there are several research stations (stations I, IV and VI) which are still in accordance with the quality standard, while the other stations are below the quality standard. Parameters that do not match the quality standards are: TDS and pH.Conclusion: The condition of the quality of the marine waters of Jikumerasa Village, Buru Regency based on physical, chemical and biological parameters, mostly still meets the specified quality standards.

Abstract

Background: Jikumerasa village has the main object of marine and beach tourism in Buru Regency. This activity has the potential to have a negative impact on community structure and distribution patterns of Bivalves, Gastropods and Echinoidea. Methods: The study was carried out in August 2022 - September 2022. Sampling used a transect measuring 1 x 1 m (1 m2). Physical and chemical parameters of the waters were measured temperature, pH and salinity. Results: There were 16 types of gastropods, 9 types of Bivalves and 3 types of Echinoidea found at the study site. Low species density and diversity. High uniformity and no dominant type. A total of 17 species had random distribution and 7 species clustered. Water temperature 29.30C - 29.60C, pH 6.3 - 6.6 and Salinity 250/00 - 300/00. Conclusion: Beach tourism in Jikumerasa Village has an impact on community structure and distribution patterns of Bivalves, Gastropods and Echinoidea. This can be seen from the few species found, low density and diversity, high uniformity, mostly random distribution patterns of species, and conditions of pH and salinity of the waters below the quality standard.
