Judul: Implementasi Pewarisan Harta Pusaka Tinggi pada Masyarakat Minangkabau.
Abstrak: Penelitian ini ditujukan untuk (1) mengidentifikasi implementasi adat matrilineal pada masyarakat Minangkabau, (2) mengidentifikasi implementasi pewarisan harta pusaka tinggi pada masyarakat Minangkabau, dan (3) menganalisis pengaruh adat matrilineal terhadap pewarisan harta pusaka tinggi di Minangkabau. Pendekatan yang digunakan adalah pendekatan kuantitatif yang didukung oleh data kualitatif. Data kuantitatif diolah menggunakan aplikasi Microsoft Excel 2013 dan SPSS for Windows versi 16.0. Data kualitatif diolah dengan cara mereduksi data, menyajikan data, dan verifikasi data serta menyampaikannya secara deskriptif analitik. Lokasi penelitian di Nagari Taluk Kecamatan Lintau Buo Kabupaten Tanah Datar Provinsi Sumatera Barat. Pemilihan tiga puluh responden dilakukan dengan teknik purposive sampling dengan kriteria tertentu. Implementasi pewarisan harta pusaka tinggi pada masyarakat Minangkabau merupakan penerapan adat matrilineal dalam proses pewarisan harta pusaka tinggi. Adat matrilineal merupakan aturan adat Minangkabau yang berdasarkan pada hubungan keibuan. Pewarisan harta pusaka tinggi merujuk pada adat matrilineal yang dianut oleh mayarakat Minangkabau yang berlansung dari satu generasi ke generasi selanjutnya.

Judul: The Influence of Matrilineal Culture on the Success of women's savings and Loan Empowerment (SPP) (Case: Nagari Paninggahan, Junjung Sirih Distric, Solok Regency, West Sumatra)
Abstrak: Budaya matrilineal merupakan sistem kekerabatan yang mengatur garis keturunan ibu yang menjadi ciri khas adat Minangkabau. Pemberdayaan masyarakat merupakan suatu proses yang bertujuan untuk meningkatkan kemampuan masyarakat dalam memanfaatkan sumber daya manusia dan sumber daya alam untuk mewujudkan kesejahteraan. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik individu, budaya matrilineal terhadap keberhasilan program pemberdayaan Simpan Pinjam Perempuan (SPP) dan pengaruh keberhasilan program pemberdayaan Simpan Pinjam Perempuan (SPP) terhadap kesejahteraan keluarga. Pendekatan yang digunakan dalam penelitian ini adalah pendekatan kuantitatif yang didukung dengan pendekatan kualitatif dengan metode wawancara mendalam. Penentuan jumlah responden pada penelitian ini adalah sebanyak 41 orang yang menggunakan uji regresi linear dan menggunakan teknik proposional random sampling. Hasil penelitian ini menunjukan budaya matrilineal indikator tingkat pengambilan keputusan berpengaruh signifikan terhadap ketepatan waktu pengembalian. Sementara itu, terdapat pengaruh yang signifikan antara keberhasilan program pemberdayaan Simpan Pinjam Perempuan (SPP) terhadap tingkat kesejahteraan keluarga penerima manfaat program., Matrilineal culture is a kinship system that regulates the maternal lineage which is the hallmark of Minangkabau customs. Community empowerment is a process that aims to improve the community's ability to utilize human resources and natural resources to achieve prosperity. This study aims to analyze the effect of individual characteristics, matrilineal culture on the success of the Women's Savings and Loans empowerment program (SPP) and the effect of the success of the Women's Savings and Loans empowerment program (SPP) on family welfare. The approach used in this research is a quantitative approach which is supported by a qualitative approach with in-depth interviews. Determination of the number of respondents in this study were 41 people who used linear regression test and used proportional random sampling technique. The results of this study show that matrilineal culture indicators of the level of decision making have a significant effect on the timeliness of returns. Meanwhile, there is a significant influence between the success of the Women's Savings and Loans empowerment program (SPP) on the level of welfare of the families of the program beneficiaries.

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.
