Judul: Fungsi Keluarga, Ketahanan Keluarga, dan Perilaku Investasi Anak pada Keluarga Petani
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh fungsi dan ketahanan keluarga terhadap perilaku investasi anak pada keluarga petani. Contoh dalam penelitian ini adalah 30 keluarga petani utuh yang memiliki anak usia prasekolah (3-5 tahun). Penelitian ini menggunakan desain cross sectional study. Lokasi penelitian berada di Desa Cikanyere, Cianjur, Jawa Barat. Contoh dan lokasi dipilih secara purposive. Hasil penelitian ini menunjukkan terdapat hubungan positif antara usia orang tua dengan fungsi keluarga; usia ibu dengan ketahanan fisik; jumlah anak sekolah dengan fungsi keluarga dan perilaku investasi anak dimensi uang dan waktu; fungsi keluarga dengan ketahanan fisik keluarga dan perilaku investasi anak dimensi uang dan waktu; dan ketahanan fisik keluarga dengan perilaku investasi uang pada anak. Sementara itu, status pekerjaan ibu berhubungan negatif dengan fungsi keluarga dan perilaku investasi anak dimensi waktu serta usia anak berhubungan negatif dengan investasi waktu orang tua terhadap anak. Hasil uji regresi menunjukkan bahwa usia anak, fungsi dan ketahanan fisik keluarga berpengaruh positif terhadap perilaku investasi anak dimensi uang. Usia anak dan pendapatan per kapita berpengaruh negatif terhadap perilaku investasi anak dimensi waktu, sedangkan fungsi keluarga berpengaruh positif terhadap perilaku investasi anak dimensi waktu. Fungsi keluarga memengaruhi positif signifikan terhadap perilaku investasi anak secara total.

Judul: Pengaruh Kesejahteraan Keluarga terhadap Investasi Anak pada Keluarga Petani
Abstrak: Child investment will determine how the quality of children and family welfare in the future. This study is aimed to investigation welfare, money investment, and time investment for children in farmer families and the influencing factors. The study was performed in 100 randomly selected families, whose primary school children with age 6-12 years. The results showed that based on the objective welfare, the farmer families could not be categorized as poor families. Education and health facilities for primary school children are in the middle category. Education expending proportion for primary school children 7.14 percent dan health expending 0.51 percent. On average, the mothers and fathers, respectively, spend 2 hours 3 minutes and 1 hour 29 minutes per day on children care. Logistic regression results showed that the increase of the family size would reduce the family welfare. Furthermore, the results of multiple linear regression revealed that age child increase, long mothers education, price asset increase, and objective welfare would increase spending for money investment. In addition, increasing child age and the objective welfare tend to reduce the time investment. However, we found that longer mothers education will increase the time investment in children.

Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
