Berbagai Dampak Hukuman (Punishment) dalam Pendidikan Terhadap Peserta Didik

All humans are obliged to be educated. The objective of the subject of education is to improve the quality of oneself in order to become a complete person. In achieving that goal, education has tools to support its smooth running. One of the educational tools punishment which is punishment, has a profound impact on learners. The punishment in education is the punishment given to the learner aimed at edifying the offending learner. After the sentencing, the impact of the learner, the impact of each learner varied, to which in the study, researchers tried to dig up information on the impact of the punishment on the learner by using literature and secondary data, that is, data from previously existing sources such as journal articles, books, and scripts. Then the data was qualitatively analyzed using the miles and hubermans' methods. Analysis has resulted in some effect on learners. The effects are positive and dam impact.

Assessment of benthic environmental disturbance in the Ba Lai estuary using the nematode biomass spectra

The researchs on the biomass spectra - a functional characteristic of biotic communities is still limited. In this study, the nematode biomass spectra in the bottom of Ba Lai estuary was investigated at six subtidal stations from the sea toward the upstream. The result showed that nematode biomass spectra ranged between -8 and 1 being significantly different between stations, and the lowest biomass of those spectras was in station BL4 (< 2 µg) which is upwardly closed to the Ba Lai dam. BL4 was also characterized by the lowest nematode abundance in the studied area. In addition, station BL3 downwardly closed to the dam exhibited low number of individuals. The heterogeneity in the nematode biomass spectra of BL3 and BL4 might due to the disturbance in the sedimentary environment of Ba Lai estuary related to the dam impact. This research again supports the important role of biomass spectra as bioindicator tool for biomonitoring and environmental quality assessment. Therefore, applying nematode biomass spectra is recommended for environmental assessment due to their advantages such as timesaving, not taxonomical expertise-requirement.

Macrofauna Communities In The Marine Section Of Ba Lai Estuary, Ben Tre Province

Macrofauna communities in Ba Lai estuary, Ben Tre province were investigated in three transects from the river mouth to the dam construction, in the order from the right, middle to the left bank. The community characteristics such as the composition, density, biodiversity, and the distribution pattern were recorded and analyzed. The results showed that the macrofauna communities in the marine section part of Ba Lai river consisted of 76 species belonging to 3 phyla: Mollusca, Arthropoda, and Annelida. In this study, it was notable that a high economic value of Ben Tre Clam (Meretrix lyrata) presented in the Ba Lai estuary with a density of 3160 ind /m2 on the right bank. The highest density was recorded in the mid transect of the river, followed by the right and the left (2907 +/- 4298, 1813 +/- 2056; 1730 +/- 1590 ind /m2, respectively). The biodiversity of macrofauna communities was measured by the species richness, Shannon – Wiener index, and Pielou's evenness. Diversity indices illustrated that the middle bank had the highest biodiversity. However, the statistical analysis results showed that the density and biodiversity indices in these transects were not significantly different. The main reason might be due to Ba Lai dam impact, which has been accreting alluvial, causing these locations gradually being similar in the environmental conditions. The distribution pattern of benthic macrofauna communities in this study should be considered as a typical distribution of benthos in rivers affected by dams. Macrofauna communities which gave rapid responses to environmental changes should be used as a bioindicator.

Temporal variability of fish larvae assemblages: influence of natural and anthropogenic disturbances

Natural and induced disturbances greatly influence the temporal distribution of ichthyoplankton abundance. This study assesses and compares the temporal variability of fish larvae assemblages in controlled and free environments to determine the influence of environment variables on the main taxa in these systems. The study was conducted at the Chapecó (without dam impact) and Ligeiro (with dam impact) river mouths, which are located in the upper Uruguay River. Samples were made between October 2001 and March 2004 during three reproductive periods. The larvae assemblages were composed of small and medium-sized Characiformes and Siluriformes. The variation in the distribution of larvae was mainly temporal (>85%). When the three reproductive periods were compared, it was observed in the second period, characterized by a larger water flow and a lower temperature, that there was a reduction in abundance, a lower number of taxa, an absence of stages in post-flexion and a high dissimilarity in larvae assemblage structure. In general, the environmental variables of water flow and temperature most influenced the distribution of egg and larvae abundance. In the studied area, a smaller temporal variability was observed in the structure of larvae assemblages at the sampling sites in the Chapecó River mouth than in in the Ligeiro River mouth under the influence of dams.

Influence of Berm Number on Safety Factor of Tailings Dam

Tailings dam safety has always been an important research field of geotechnical engineering world, and research on safety factor of dam is an important indicator of stability of tailings dams. In this paper assumed that Sweden arc method and simplified Bishop method were used to analyze influence of berm number on safety factor of tailings dam in some condition. Results showed that change of berm number had an impact on total safety factor of dam; Impact of change of berm number on safety factors was also different at different intervals. The influence analysis of changes of berm number on safety factor of dam had directive significance for design and construction on site.
