Judul: Analisis Pengaruh Pemberian Insentif Terhadap Kinerja Karyawan di PT RJW.
Abstrak: Provided incentives for employees gives a considerable impact to the employee’s performance. The objective of this study is to identify the dominant factor of incentives and performance, to analyze the affecting the incentives provision to the performance and to analyze the Spearman correlation of characteristic of respondents to the performance of employees in PT RJW. The methods used in this research is Structural Equation Modeling (SEM) with Partial Least Square (PLS) by using SmartPLS and SPSS software for Spearman correlation analysis. Correlation coefficient from Spearman correlation test (rho) that is close to zero indicates that there is no significant relationship between two test variable and produce  above 5%, which meanssignificant for the age category of the performance indicators. Then the period of employment and education categories to later category to several indicators with  below 5%, which mean sinsignificant for the period of employment and education categories to performance quantity. Chi square contingency analysis result showed no significant relationship between gender with performance. The measurement model evaluation of incentives variable shows that job promotion indicator gives the most significant contribution in shaping performance. The result of structural model evaluation shows that incentives variable has a significant positive impact to performance variable.

Judul: Pengaruh Insentif Terhadap Kinerja Karyawan PT SPP
Abstrak: Pemberian insentif kepada karyawan memberi dampak cukup besar terhadap kinerja karyawan. Penelitian ini bertujuan mengidentifikasi faktor dominan pembentuk insentif dan kinerja, menganalisis pengaruh insentif terhadap kinerja dan menganalisis korelasi Spearman karakteristik responden terhadap kinerja karyawan PT SPP. Metode dalam penelitian dilakukan dengan Structural Equation Modeling (SEM) dengan Partial Least Square (PLS) menggunakan perangkat lunak SmartPLS dan SPSS untuk analisis korelasi Spearman. Hasil uji korelasi Spearman (ρ) menunjukkan nilai koefisien korelasi untuk semua karakteristik responden (pendidikan, usia, dan masa kerja) dengan α 5% berada di atas nol, artinya semua karakteristik responden berkorelasi signifikan terhadap kinerja meskipun tingkat hubungan korelasi paling tinggi yaitu hubungan lemah. Usia terhadap kuantitas pekerjaan menunjukkan nilai correlation coefficient paling tinggi karena jenis karyawan yang menjadi responden yaitu jenis high employee sehingga tidak menutup kemungkinan untuk karyawan dengan usia tinggi memiliki kinerja yang baik. Hasil analisis chi square kontingensi menunjukkan hubungan yang tidak signifikan antara jenis kelamin terhadap kinerja. Hasil analisis evaluasi model pengukuran variabel insentif (eksogen) menunjukkan indikator tunjangan kesehatan memberikan kontribusi terbesar pembentuk insentif. Hasil analisis evaluasi model pengukuran variabel kinerja (endogen) menunjukkan indikator kualitas pekerjaan memberikan kontribusi terbesar pembentuk kinerja. Hasil analisis evaluasi model struktural menunjukkan variabel insentif berpengaruh positif terhadap variabel kinerja secara signifikan.

Judul: Hydrothermal Synthesis of Biphasic Calcium Posphate
Abstrak: Biphasio calsium phosphate (BCP), which was a mixture of hydroxypatite (HA) and tricalcium phosphate (TCP), was synthesized by hydrothermal method followed by sintering process. Hydroxyapatite was produced by using natural calcium source CaO from hen's eggshell and (NH4)2HPO4 as phosphate souce, other hydroxyapatite sample was produce by using synthetic calcium source Ca(OH) and H3PO4 as phosphate source.
