Abstract

This study aims to examine the impact of corporate social responsibility (CSR) on corporate performance in Indonesia and examine the role of intellectual capital as a moderating variable that can increase the influence of CSR on company performance. Hierarchical regression analysis is used to test the effect of CSR on performance and test intellectual capital as a moderating variable that can increase the influence of CSR on corporate performance. This study uses 147 samples of observation data from manufacturing companies listed on the Indonesia Stock Exchange (IDX) during the year 2013-2015. The results showed that CSR has an effect on company performance as measured by Return on Asset (ROA). The higher CSR disclosures made by the company then can improve the company's performance (ROA). The results of this study also show that intellectual capital as a moderation variable is proven empirically able to increase the influence of CSR on company performance. These results indicate that the improvement of intellectual capital of the company including human capital, relational capital, and structural capital can increase the influence of CSR on company performance (ROA).

Abstract

Kelapa sawit merupakan tanaman monokotil dan monoecious, yaitu bunga jantan dan bunga betinadijumpai secara terpisah pada satu tanaman. Karena sifatnya yang monoecious, tanaman kelapa sawit memerlukanperantara yang mampu memindahkan serbuk sari dari bunga jantan ke bunga betina yang sedang anthesis yaituserangga Eleaidobius kamerunicus. Penelitian ini bertujuan untuk mempelajari populasi kumbang E. kamerunicusdan faktor-faktor lingkungan yang mempengaruhinya. Populasi kumbang diamati pada tandan bunga jantan kelapasawit dengan metode stratified random sampling. Perbedaan populasi serangga E. kamerunicus dan faktor-faktorlingkungan dianalisis dengan ANOVA. Hubungan antara faktor-faktor lingkungan dan populasi kumbangdianalisis dengan korelasi Pearson. Hasil penelitian menunjukan bahwa populasi serangga E. kamerunicus diperkebunan Afd. IV Kebun Bangun PTPN III Kabupaten Simalungun telah memenuhi kebutuhan seranggapenyerbuk dalam proses penyerbukan untuk menaikkan jumlah produksi kelapa sawit yaitu lebih dari 20.000ekor/ha. Jumlah spikelet mempengaruhi jumlah populasi serangga E. kamerunicus, sedangkan suhu dankelembaban udara tidak mempengaruhi populasi serangga E. kamerunicus.Kata kunci : Eleaidobius kamerunicus, kelapa sawitABSTRACTOil palm is a monocotyle crop and monoecious, the male flowers and female flowers found separately ona single plant.

Abstract

Cadmium usually use as a commound in coloring agents that commonly used in industry. It's toxic and undistangleable in water. The polluted water will give the bad effects to the biota and human too. Melanoides turricula is kind of gastropod, acts as a strong bio accumulator in accumulating heavy metals. The purpose of this research is to analyze the concentration of kadmium and its correlation with the existence of M turricula on Wangan River. This research was done in Wangan River, Sokaraja. The research method that is used is survey between the concentration of cadmium in M. turricula's body and the water of Wangan River is analyzed by Spearman Rank's Correlation Analysis. The result of the research shows that there are lowest cadmium method. The objects of the research are M. turricula and Wangan River's water. The independent variable that has been observed is the concentration of cadmium in Wangan River's water and the dependent variable is the concentration of cadmium in M. turricula's body. The main parameters measured are the concentration of cadmium on both M. turricula's body and Wangan River's water. The supporting parameters are temperatures, pH and BOD (Biochemical Oxygen Demand). The samples are taken four times in four months on three observations station. Those are the unclouded area, the polluted area and the waste disposal area. The correlation concentration on the M. turricula and river's water, before given any waste, around 2.075 µg/g and 0.750 µg/L. In the area of waste disposal station, there are the highest cadmium concentration on the M. turricula and also on the river's water around 6.450 µg/g and 1.050 µg/L. Meanwhile the cadmium concentration on the M. turricula and on the river's water, after given waste, are around 4.600 µg/g and 0.875 µg/L. Based on Spearman's Rank Correlation Analysis, it is shown that there is a correlation between cadmium concentration with M. turricula and river's water.
