Hubungan Antara Sinyal Dividen Tunai Dengan Kinerja Operasional Dan Kinerja Pasar

This research aims at examining dividend-signaling hypothesis by testing the relationship between dividend changes and operational performance as well as market performance. The sample consists of 75 firms for the period 2000-2005. The analysis employed are multiple regressions and event study. The results on operational performance show that (1) dividend increase (with earnings increase or earnings decrease) correlates significantly with the increase of next period company 's profitability, (2) dividend decrease and earnings decrease negatively correlate with next period company's profitability, (3) dividend decrease and earnings increase positively correlate with next period company 's profitability, and (4) unchanged dividend does not correlate with next period company's profitability. The evidence on market performance (cumulative abnormal return surrounding dividend announcement date) shows that dividend changes have significant effect on cumulative abnormal return for five and ten days around announcement date. Evidences from this research show that dividend signaling hypothesis is not fully supported

Variability and Spatial Distribution of Total Scattering Coefficients of Surface Water in Various Seasons

Variability and spatial distribution data of the total scattering coefficients ares useful in the development of bio-optical algorithms of ocean color satellite. The purpose of this study was to determine the variability and spatial distribution of the total scattering coefficient at 9 wavelengths (λ) in different seasons. Field data collection were conducted in the Northeastern Gulf of Mexico (NEGOM) of the spring , summer, and fall in 1999-2000 by using the ac-9 in-situ Spectrophotometer and restricted to coastal waters of 10 m isobath and offshore of 1000 m isobath. The data were filtered using the moving average method and tested with the Kruskal-Wallis. The results showed that the average value of the total scattering coefficients were significantly different among spring, summer, and fall. In general, the total scattering coefficients were relatively high, especially in the coastal waters near the mouth of the river each season and relatively low in offshore waters except during the summer that the total scattering coefficients were also relatively high in offshore watersdue to the intrusion of the Mississippi river flow toward offshore containing high nutrients that can promote the growth of phytoplankton in the offshore, suspended material and lower salinity jointly to increase the total scattering coefficients

Analyze the Contract of Broiler Partnership Farming System in the Province of South Sulawesi in Conjunction to the Law No. 5, 1999 Regarding Prohibition on Monopolistic and Unfair Business Competition

This research aimed to analyze the contract of broiler partnership farming system in the Province of South Sulawesi in conjunction to the Law No. 5, 1999 regarding prohibition on monopolistic and unfair business competition. This research was carried out from August 2013 till October 2013 in Maros and Gowa Districts of South Sulawesi. All broiler farmers were treated as the population of the study and farmers having contract with any company in the region were taken as the samples giving total number of sample was 50 farmers. The results of study showed that the implementation of partnership was in line with the contract. However, there were some points of the contract which were not well implemented by both parties, such as the late harvest time and the late payment in which these did not comply with the Law No. 5, 1999

Study of Shoreline Changes at Jeneberang River Delta, Makassar

The study of shoreline changes during 1990 - 2008 in the delta of the River Jeneberang, Makassar was conducted by evaluating sediment transport into and out of a cell. Longshore sediment transport was computed by considering the influence of heights and angles of the breaking waves. Results of calculation of sediment transport showed that the dominant of sediment transport was to the north during the arrival of the southwest and west waves, and to the south when the wave coming from the northwest. Comparison between shore profiles resulting from model and coastline satellite imagery showed similarity. The difference between the two tend to be occurred at the head land part of the shoreline. This was due to complexity of coastal dynamic at the area. The results of the 19 years shoreline simulation showed that there was a tendency of abrasion at the upsteam head land part as the wave energy tend to converge and accretion at the bay part as the wave energy tend to diverge. Abrasion mainly occurred at Tanjung Bunga (head land) where the coast retreat 181.1 m. Accretion occur in the bay area (Tanjung Merdeka) where the coast advance to the sea for about 59.8 m. The shoreline tend to be stable when the profile was straight such as Barombong Coast

Complexity within an oil palm monoculture : The effects of habitat variability and rainfall on adult dragonfly (Odonata) communities

Recent expansion of oil palm agriculture has resulted in loss of forest habitat and forest‐dependent species. However, large numbers of species—particularly insects—can persist within plantations. This study focuses on Odonata (dragonflies and damselflies): a charismatic indicator taxon and a potentially valuable pest control agent. We surveyed adult Odonata populations biannually over three years within an industrial oil palm plantation in Sumatra, Indonesia. We assessed the effects of rainfall (including an El Niño Southern Oscillation‐associated drought), the role of roadside ditches, and the importance of understory vegetation on Odonata populations. To assess the impacts of vegetation, we took advantage of a long‐term vegetation management experiment that is part of the Biodiversity and Ecosystem Function in Tropical Agriculture (BEFTA) Programme. We found 41 Odonata species, and communities varied between plantation core and roadside edge microhabitats, and between seasons. Abundance was significantly related to rainfall levels four months before surveys, probably indicating the importance of high water levels in roadside ditches for successful larval development. We found no significant effect of the BEFTA understory vegetation treatments on Odonata abundance, and only limited effects on community composition, suggesting that local understory vegetation structure plays a relatively unimportant role in determining communities. Our findings highlight that there are large numbers of Odonata species present within oil palm plantations and suggest that their abundance could potentially be increased by maintaining or establishing waterbodies. As Odonata are predators, this could bring pest control benefits, in addition to enhancing biodiversity within intensive agricultural landscapes.publishedVersionPaid Open Acces
