Abstract. Hasidu LOAF, Jamili, Kharisma GN, Prasetya A, Maharani, Riska, Rudia LOAP, Ibrahim AF, Mubarak AA, Muhasafaat LO, Anzani L. 2020. Diversity of mollusks (bivalves and gastropods) in degraded mangrove ecosystems of Kolaka District, Southeast Sulawesi, Indonesia. Biodiversitas 21: 5884-5892. Mollusks are one of the mangrove organisms whose classes are bivalves and gastropods. It plays an important role in mangrove and marine ecosystems as filter feeders, predators, and herbivores. This study aims to knows the diversity and abundance of mollusks (bivalves and gastropods) in several mangrove ecosystems in the Kolaka coastline as well as the similarity of these locations. This study was conducted in mangrove ecosystems of Induha Village, Mangolo Village, Tahoa Village, and Towua Village of Kolaka District, Southeast Sulawesi, Indonesia, from July to August 2019. This is a transect method stretched along a 100 m line perpendicularly from the seaward. The size of the mollusks subplot was 1 m2 and placed along the line transect. Each line transect comprises 10 subplots. To analyze the diversity index, evenness index, and its abundance, Kaleida Graph 4.0 version was used. This research indicates that the mollusks consist of 4 families of bivalves with 6 species and 10 families of gastropods with 182 species. It also found out 23 species of mollusks scattered to each location. The molluscan species which spread in all four mangrove ecosystems were Terebralia sulcata, Nerita planospira, and Batillaria multiformis. In Induha, the mollusks species were Anadara notabilis and Drupella margariticola. Meanwhile, Saccostrea cucullata, Pirenella incisa, Clithon oualaniensis, and Clithon pulchellum were only found in Towua. The diversity index of bivalves in each location was categorized as low diversity index category, as well as gastropods were categorized as medium diversity index. The highest diversity index of gastropods was in Induha (H' = 1.96). It was supported by the good mangrove ecosystem for mollusks' habitat. The lowest diversity index of gastropods was in Towua (1.41). This research depicts that three kinds of species with high abundance rate whose rates were >1 ind/m2are located in two different locations namely; P. incisa (3.9 ind/m2) and S. cucullata (3.2 ind/m2) in Towua and followed by B. multiformis (2 ind/m2) and Isognomon ephippium (1.2 ind/m2) in Mangolo.

The method used in this study is a survey method with a purposive sample. The sample in this study amounted to 12 people, consisting of 5 people from the Department of Marine Affairs and Fisheries of Kendari City and seven people who manage the Bungkutoko mangrove tracking. Primary data collection is done through direct observation in the field and structured interviews with the help of questions. Secondary data collection was obtained through literature studies. Analysis of the data used includes quantitative research with the Rapid Appraisal for Fisheries (RAPFISH) method that has been modified to Rap_Mforest and qualitative analysis (descriptive). The result showed the status of sustainability management of mangrove ecosystems. The institutional dimension is in the quite sustainable category (53.67). The attribute leverage analysis on the institutional extent shows that the most sensitive attribute to affect sustainability in the institutional dimension is the role of formal institutions that support mangrove ecosystem management. Even a slight change in this attribute will affect the institutional sustainability of the mangrove ecosystem. The legal institution, in this case, is the Kendari City Government through the Kendari City Marine and Fisheries Service

Interest in this research arises from one of the things that sometimes escape the attention, namely the gender tendency toward a major in college. This study used final teenage data at first year students at Yogyakarta State University to see how gender differences can represent aspirations for science and social-humaniora majors. Data were collected using a scale. Scale was distributed to 425 respondents by sampling propotioned cluster random sampling. Using the survey method we found that men dominate in the exact plane of about 62.5% and women about 37.4%. The opposite is shown in the non-exact plane dominated by women with a percentage of about 80.4% and about 19.5% of males. This difference is also supported by other factors such as the importance of achievement beliefs in the department, and gender stereotypes in the community that are still inherent. This research is expected to contribute to the literature on career development and can form the basis of the formulation of career guidance programs that can include attention to gender differences

Its crucial to get information about lead (Pb) heavy metal pollution from mining and oil palm plantation on species density in mangrove ecosystem, to anticipate its impacts. This study aimed is to compare the types and densities of vegetation in mangrove ecosystems allegedly due to mining in Setarap village, Tanah Bumbu Regency and oil palm plantations in Kuala Tambangan Village, Tanah Laut Regency. We also analysis the condition of waters (TDS, pH and DO) and organic content in sediments to acquire data from the South Kalimantan mangrove ecosystems. The results showed there were four species of true mangroves (Avicennia alba, Acanthus ebracteatus, Nypa fruticans and Rhizophora apiculate) could live well in the environment affected by mining or oil palm plantations. The species density for trees was low (933 ind/ha) for mangroves affected by coal mines, while those affected by oil palm plantations had higher densities (1,067 ind/ha). pH value of waters in affected area by coal mining showed more acidic value (pH 5.76) especially at the back, while those by palm oil plantations are more acidic (pH 6) in the estuary. Organic matter content in sediments affected by coal mines was in the range of 0.61-6.59%, while those affected by oil palm plantations showed higher values (0.12-2.19%). Lead heavy metal content (Pb) in waters affected by coal mines was 0.031-0.056 mg/L, while the area affected by oil palm plantations was of higher value (0.110-0.128 mg/L). Lead (Pb) levels in sediments indicate higher values than waters, which reach 3.512-6.046 mg/Kg (affected by coal mines), and in areas affected by oil palm plantations reaching 6.658-6.66 mg/Kg. The general conclusion is that vegetation densities in areas affected by coal mines are lower than oil palm plantations. The level of lead (Pb) pollution in the sediments is higher than in the waters.

The time of occurrence of 12 neuromuscular patterns of behavior in the development of 2 groups of Negro infants from different socio-economic levels during the first year of life is presented. The Negro infants from the clinic showed acceleration over the Negro infants from private practice in their development from the 8th to the 35th week of life, after which time, the development of the 2 groups was essentially the same. The Negro infants as a group showed acceleration in their development when compared with a group of white infants studied in a similar manner by Aldrich except in 2 patterns, "smiling" and "vocalization." A marked similarity was noted during the first 30 weeks of life in the development of the white and Negro infants from private practice whose socio-economic backgrounds were substantially similar. The differences and similarities observed in the neuromuscular behavior in the 3 groups studied may be attributed mainly to environmental factors. The observed acceleration in the Negro infants is apparently an expression of greater permissiveness in daily care as practiced by the mothers or mother substitutes in the lower socio-economic classes.
