Abstract

Atactodea striata (Gmelin, 1791) are inhabitants of the sandy at Village Ohoider, Kei Kecil Islands, MalukuTenggara. Sampling has been carried out on the 15th of September 1997 to October 1998 for the shell heightmeasurement. Monthly length frequency data were then analyzed using the software FiSAT II to estimatepopulation parameters such as population structure, age maximum, maximum length, growth and recruitment.Result obtained from this study is that Atactodea striata shells generally consist of four age groups, except in certainmonths were widened to five because of the occurence of old shell group. Mussels in this study reproducemultivoltine with expected life span of almost four years. The maximum length of the mussels is 19.03 mm at 95%confidence level, and the growth coefficient K = 0.37 with a growth performance index Ï? '= 1.74. Observations onhabitat sediment discovered that these shells prefer to live in the fine sand with range of fire grain of 65.96 to69.09%.Keywords:: Dynamics Population, Atactodea striata, Kei Kecil Islands, Maluku Tenggara

Abstract

ABCTRACTThe Ecology of Landsnail in Ciremai National Park. Twice fieldworks in order tocollect landsnails of Ciremai National Park were conducted, approximately in ArgamuktiVillage of western part of the park and Linggajati Village of eastern part of the park.They resulted 48 species of landsnails of 15 families. Thirty two species were found inArgamukti whereas 28 species were found in Linggajati. However, biodiversity indexescomparison for both locations were unsignificant at 95% level of confidence. Bothlocations were also populated by specific landsnails, only 40% of the whole landsnailswere live in Argamukti and Linggajati. The highest densities in entire locations weredominated by microsnails and mostly were live in lower latitude. Cluster analysis forspecies and habitat used NTSYSpc 2.10p. programs for Jaccard similarity index revealed6 groups of species and habitats respectively.Keywords: ecology, landsnail, biodiversity, density, cluster

Abstract

ABSTRACTThis paper presents the results of a survey on intertidal molluscs in 3 habitats (Seagrass bed, coral reef, and sandflat) in Tanimbar Islands of West South-east Moluccas, Indonesia. Six relatively large and two small islands were attained to perform 125 plots of 34 stations. Molluscs? diversity in each habitat were calculated using Shannon-Wiener formulation whereas Mann-Whitney formulation for comparing between habitats. Multivariate analyses for clustering of PAST 2.17 was utilized to further the analyses. A number of 101 species gastropods (26 families) and 51 species of bivalves (19 families) were recorded. Seagrass bed was inhabited by 100 species, followed by coral reef by 85 and sandflat by 44 species. Shannon-Wiener indexes for molluscs? diversity range in seagrass was 0.39 to 1.29, in coral was 0.27 to 1.14 and in sandflat was 0.52 to 0.99. Clustering analyses for stations revealed that three stations in seagrass were the most dissimilar, followed by one station in coral due to habitat. Clustering analyses for species found four dissimilar groups of molluscs, whereas a group has many consimilar members.Keywords: Seagrass, coral, sandflat, diversity, clustering

Abstract

Kendaraan bermotor listrik (KBL) berperan penting dalam peningkatan efisiensi energi, ketahanan energi, konservasi energi sektor transportasi, dan terwujudnya energi bersih, kualitas udara bersih dan ramah lingkungan, serta komitmen Indonesia menurunkan emisi gas rumah kaca. Untuk mendukung hal tersebut pemerintah telah menetapkan Peraturan Presiden No. 55 tahun 2019. Ketika melakukan perjalanan terdapat beberapa hal yang perlu dicatat untuk pengambilan data seperti jam berangkat, lokasi keberangkatan, kondisi baterai dan kWh pada saat berangkat, jam tiba di titik pemberhentian, sisa baterai, kWh ketika tiba, mode berkendara, jarak tempuh, kondisi jalan, rata-rata kecepatan, dan besar AC. Pada saat pengisian diantaranya jam mulai, lokasi pengisian, presentase baterai pada saat mulai dan selesai, jam selesai dan konsumsi kWh ketika 80% dan ketika 100% atau selesai pengisian, total kWh, serta jenis charger. Jarak yang telah ditempuh sekitar 180,6 km dengan total konsumsi baterai 154%. Total waktu pada saat melakukan pengecasan 173 menit, total konsumsi kWh untuk pengisian sebanyak 25,03 kWh dan ketika perjalanan sebesar 24,54 kWh dan ketika perjalanan di dapat nilai efisiensi 7,36 km/1 kWh, estimasi biaya yang dikeluarkan untuk kWh ketika perjalanan sebesar Rp. 36.007,05 atau setara dengan 4 liter pertamax, sedangkan untuk kWh pengisian sebesar Rp. 36.726,01 atau setara dengan 4,08 liter pertamax.

Abstract

The purpose of this study is to analyze the relevance of morality with student achievement so that its contribution to learning achievement is known. This research includes the type of verification research conducted through data collection in the field using survey methods. The unit of analysis was taken using a simple random sampling technique. Data were collected through observation, interviews, questionnaires, and documentation. This study consisted of two variables, namely morality as the independent variable, and student learning achievement as the dependent variable. The results of the study show that the correlation between moral reasoning and student achievement is 0.683 (the degree of relationship is strong). This means that students' morality reasoning is 46.65% determined by learning achievement factors, and 53.35% is determined by other factors.

Abstract

This study aims to explore and evaluate the effectiveness of zakat distribution as a mechanism for alleviating the poor. The approach used in this study is the study of literature or library research. The results of this study indicate that the effect of zakat distribution on efforts to reduce poverty is varied in each region. Even so, the distribution of zakat funds has a positive effect, but the influence of zakat is varied. There is even a small impact on increasing the income of the poor and economic growth. This is caused by different perspectives in various regions. Therefore, the management of zakat needs to be adjusted with the recipient's profile of zakat (mustahik). Within the national (macroeconomic) framework, zakat funds can be used to increase the purchasing power of the poor and economic growth, thereby narrowing the gap between rich and poor people. In general, muzaki and mustahik have the same view on the aspect of zakat, namely as an activity of worship.
