Judul: The Effect of Motivation and Reference Group Towards Property Insurance Purchasing Decision in PT Asuransi Wahana  TataPondok Indah, Jakarta
Abstrak: Kebutuhan konsumen akan tempat tinggal yang semakin meningkat, menyebabkan meningkatnya pembangunan rumah tinggal dan apartemen. Hal ini menyebabkan banyak perusahaan asuransi properti yang menawarkan produknya. Beberapa faktor yang mempengaruhi keputusan konsumen adalah motivasi dan kelompok acuan. Tujuan penelitian ini adalah mengetahui pengaruh motivasi dan kelompok acuan terhadap keputusan pembelian asuransi properti. Metode pengambilan sampel yang digunakan adalah non probability sampling dengan teknik purposive sampling dan alat analisis yang digunakan adalah analisis deskriptif dan analisis regresi linier berganda. Hasil penelitian ini berdasarkan analisis deskriptif adalah sebagian besar nasabah asuransi properti di dominasi oleh laki – laki berusia 25-35 tahun yang berprofesi pegawai swasta dengan pendidikan terakhir adalah S1 dan pendapatan perbulannya adalah Rp.3.500.000- Rp.7.000.000. Selain itu, hasil analisis regresi linier berganda menunjukan bahwa motivasi dan kelompok acuan tidak berpengaruh nyata terhadap keputusan pembelian asuransi properti dikarenakan nilai p- value >0,05.

Judul: Analisis Minat Kepemilikan Asuransi Kesehatan Swasta dengan Structural Equation Modelling (Studi Kasus: Jawa Barat)
Abstrak: Asuransi kesehatan merupakan instrumen pengalih risiko yang berkaitan dengan kondisi kesehatan seseorang. Jumlah kepemilikan premi asuransi kesehatan swasta di Jawa Barat mengalami fluktuasi dari tahun 2013 – 2017. Minat merupakan suatu faktor penting yang mempengaruhi perilaku seseorang dalam memiliki asuransi kesehatan swasta. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang membangun model minat kepemilikan asuransi kesehatan swasta dan mengetahui kontribusinya dalam mempengaruhi minat. Model minat yang digunakan berbasis pada Theory of Planned Behaviour (TPB), sementara pendugaan parameternya digunakan Structural Equation Modelling (SEM). Penelitian ini melibatkan 150 responden yang berdomisili di Jawa Barat, berusia 21 – 50 tahun, dan belum memiliki asuransi kesehatan swasta. Teknik sampling yang digunakan adalah non-probability snowball sampling. Hasil penelitian menunjukkan variabel laten sikap terhadap perilaku berpengaruh signifikan secara positif terhadap minat kepemilikan asuransi kesehatan swasta, dengan indikator usia sebagai faktor yang dominan., Health insurance is an instrument to divert risk related to one’s health condition. The number of private health insurance premium ownership in West Java fluctuated from 2013 – 2017. Intention is an important factor that affects one’s action to own private health insurance. This study aims to find out which factors define the private health insurance demand model and its contribution to intention. The intention model is based on the Theory of Planned Behaviour (TPB), whereas its parameter estimation uses Structural Equation Modelling (SEM). This study involves 150 respondents who reside in West Java, age ranging from 21 – 50, and do not own any private health insurance. Non-probability snowball sampling is used as the sampling technique. This study shows that attitude towards behaviour latent variable significantly affect intention positively, with age as the dominant indicator.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
