Judul: Pemodelan Rata-rata Besar Klaim Asuransi Kendaraan Bermotor dengan Generalized Linear Model.
Abstrak: Asuransi kendaraan bermotor adalah salah satu jenis asuransi umum yang banyak digunakan. Seiring meningkatnya volume kendaraan bermotor, risiko yang ditumbulkan, seperti kecelakaan, juga meningkat. Dalam karya ilmiah ini, dilakukan pemodelan rata-rata besar klaim asuransi kendaraan bermotor dengan Generalized Linear Model (GLM). Dalam penelitian ini, data yang digunakan adalah data asuransi kendaraan bermotor di Massachusetts dari tahun 1993-1998 dengan tertanggung memiliki tiga karakteristik, yaitu wilayah geografis, pendapatan perkapita dan populasi penduduk per mil2. Pengujian sebaran dilakukan dengan menggunakan uji Anderson-Darling dan didapatkan sebaran rata-rata besar klaim mengikuti sebaran gamma. Uji-t dilakukan untuk melihat signifikansi parameter. Model dievaluasi dengan memilih nilai Akaike’s Information Criterion (AIC) terkecil dari dua model GLM. Akurasi model dihitung menggunakan Mean Absolute Percentage Error (MAPE) dan diperoleh hasil sebesar 10.85%.

Judul: Modelling Claim Frequency of Motor Vehicle Insurance with Generalized Linear Model
Abstrak: Penting bagi suatu perusahaan asuransi untuk memperkiraan frekuensi klaim peserta asuransi di masa depan. Hal ini dapat dilakukan dengan memodelkan frekuensi klaim tersebut untuk meminimumkan kemungkinan kerugian. Terdapat beberapa faktor yang memengaruhi pendugaan frekuensi klaim. Faktor tersebut antara lain karakteristik mobil (usia kendaraan, mesin kendaraan, dan lain-lain) dan data pengemudi (usia, jenis kelamin). Dalam karya ilmiah ini frekuensi klaim tahunan dimodelkan menggunakan Generalized Linear Model (GLM) dengan mempertimbangkan faktor-faktor yang memengaruhi. Terdapat 3 model GLM, yaitu GLM1, GLM2, dan GLM3. Ketiga model tersebut didapat dengan cara mereduksi parameter yang digunakan. Model yang paling cocok adalah model GLM2 dengan nilai AIC terkecil, yaitu 254283., It is important for insurance companies to estimate the future claims frequency. This can be done by modelling the claims frequency to minimize the risk of losses. There are several factors that have an impact on the estimation of claims frequency in the future. These factors include car characteristics (vehicle age, vehicle engine, etc.) and driver data (age, gender). In this manuscript, the frequency of annual claims is modelled using Generalized Linear Model (GLM) by considering another impactful factors. There are three GLM models, GLM1, GLM2, and GLM3. Those three models are obtained by reducing used parameter. The most suitable model is GLM2 with the smallest AIC value 254283.

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.
