Abstract

The purpose of this study was to determine the Pb and Cd heavy metal content in sediments and their relationship with marine biota in Tulehu waters. The method used in the study was a survey by sampling at three research stations based on the representation of different characteristics at the study site. Station 1 at Tulehu Port 1 (non-operating and anthropogenic ship docker), Station 2 Tulehu Port 2 (ferry port) and Station 3 at Muara Sungai along Tulehu waters. The heavy metal content of Pb and Cd was measured using AAS (Atomic Absorption Spectroscopy). The heavy metal content of Pb and Cd has a effect on abundance and diversity of marine biota in Tulehu waters. This is evidenced by the Pb regression of marine biota abundance and diversity with values ​​r = 0,894 and Cd = 0.895. Increased content of heavy metals in sediments was followed by a decrease in the diversity of marine life in Tulehu waters.

Abstract

Migratory birds are birds that fly or move from their breeding place to their non-breeding location. Migratory birds usually migrate to the southern part of the earth or tropical regions to avoid limited resources during winter in their breeding areas (Bildstein, 2006). Bird of Prey or Raptors are a group of birds that frequently migrate. Raptors carry out-migration in several areas which are commonly referred to as flyways. Indonesia is also part of the flight path for migratory birds (Sukmantoro et al., 2007). At this time there were approximately 17 types of migrant raptors in Indonesia. Research on raptor migration has been carried out for a long time in various regions. In the Yogyakarta area, there have been observations of a migrant raptor, but there are no official publications and research on migrant raptor in the Bukit 76 Kaliurang area, Yogyakarta. Therefore this research was conducted to know about migratory raptor in Yogyakarta. This research was conducted at Bukit 76 Kaliurang, Hargobinangun, Pakem, Yogyakarta. The research was conducted in December 2019-March 2020, July-August 2020, and October-November 2020. This research was conductes through observations in the morning at 07.00-11.00 WIB using birdwatching techniques and purposive methods. The results of this study recorded 1 species of migrant raptor, namely the Oriental Honey-buzzard (Pernis ptilorhynchus) and 2 species of resident raptors, namely the Crested Serpent Eagle (Spilornis cheela) and the Brahminy Kite (Haliastur indus).

Abstract

The health impact for active and passive smokers is damage to the organs and respiratory tract. The body organs initially experience inflammation which increases the number of white blood cells, one of which is an increase in lymphocytes. One of the efforts to reduce the damage caused free radical by cigarette smoke is by consuming Calcitriol. Objective: To determine the effect of presenting Calcitriol on lymphocyte levels in male Wistar rats (Rattus norvegicus) exposed to cigarette smoke. Methods: This type of research is a pure experimental (true-experiment) using a pre and post-test research design with a control group design to check lymphocyte levels in male Wistar rats (Rattus norvegicus). 24 rats were divided into 6 groups simultaneously. Random, namely the control group 1 (exposed to cigarette smoke and not given Calcitriol), group 2 (exposed to cigarette smoke and not given Calcitriol), placebo control group (exposed to cigarette smoke and given olive oil), treatment 1 (exposed to cigarette smoke and given Calcitriol with a dose of 0.25 µgr / head), treatment 2 (exposed to cigarette smoke and given Calcitriol at a dose of 0.5 µgr / head) and treatment 3 (exposed to cigarette smoke and given Calcitriol at a dose of 1 µgr / head). Results: Paired t-test lymphocyte levels showed evidence that stated (p <0.05) in the K2 group (p = 0.014), the K3 group (p = 0.049), the P1 group (p = 0.012) and the P3 group (0.001) . Meanwhile, group K1 (p = 0.115) and group P2 (p = 0.066) had no statistical difference. Conclusion: Calcitriol administration can reduce lymphocyte levels in male Wistar rats exposed to cigarette smoke.
