Abstract

Macroinvertebrates are one of the bioindicators in aquatic ecosystems. The diversity and distribution patterns of functional groups of macroinvertebrate communities are assessed to determine water quality. The objective of this research was to figure out the abundance and distribution of macroinvertebrates in Watu Lumbung Beach, Gunungkidul, Yogyakarta. This study was conducted in May 2022 with the quadrat transect method using 1×1 m quadrats along Watu Lumbung Beach, Gunungkidul, Yogyakarta. Sampling was conducted at two randomly determined stations from the lowest low tide to the middle of the sea. The first station is located near Watu Lumbung reef, which has a distance of 50 m, while the second station is 250 m from the reef, so the distance between stations is 200 m. The Shannon-Weiner diversity index (H') was calculated by analyzing the data. The data obtained in this study are the results of the inventory of macroinvertebrate species at each sampling point and the number of individuals of each species. The results showed the abundance of macroinvertebrates on Watu Lumbung beach found as many as 16 species belonging to 13 families and classified into nine classes (Polychaeta, Malacostraca, Anthozoa, Echinoidea, Ophiuridae, Gastropoda, Polyplacophora, Pilidiophora and Demospongia). The family Ophiocomidae (Ophiocoma erinaceus and Ophiocoma scolopendrina) were the most abundant species at both observation stations. The diversity index is 1.94, which shows that the diversity of macroinvertebrates on Watu Lumbung Beach is categorized as moderate.

Abstract

Breeders with superior genetics will pass on the gene to the next generation. Efforts to improve the genetic quality and livestock population require selection of breeders to improve good livestock performance. This study aims to determine the comparison of livestock body size with the size required in SNI and the comparison of buffalo with intensive and semi-intensive maintenance systems. This study used a purposive sampling method for sampling. The samples used were pregnant and lactating breeders in Kejambon Village and Surajaya Village. Differences in maintenance systems for female and lactating breeders were analyzed using the t-test. The results showed that the Body Scoring Condition (BCS) value was not significantly different (P>0.05). The body size of pregnant female breeders showed a significant difference (P<0.05) except for shoulder height and body weight. While in lactating female breeders, all parameters were not significantly different (P>0.05). The conclusion is that BCS observations show that pregnant and lactating breeders that are intensively and semi-intensively maintained meet the standards as breeders. In the morphometric measurements of the body of female and pregnant breeders that are intensively and semi-intensively maintained, all meet the standards in SNI. The morphometry of pregnant sows kept intensively was higher than that of semi-intensive sows, while that of lactating sows kept intensively was lower than that of semi-intensive sows.
