Judul: Family-based human resource development: analysis of detrimental effect of unhealthy parenting on characters deficit of children
Abstrak: Mainstreaming paradigm of human resource development recently has paid serious attention to the family institution as the primary loci of human development. One of the aspects of the family institution most experts stressed was the effect of parenting on child development. In this context, parenting is defined as the skill of parents to meet the rights of their children to optimize their growth and development. Including in the concept is the moral responsibility of parents to build character of their children. This march was designed to analyze the effect of parenting on child development in two ethnical setting i.e. Banjareese and Madureese. A conceptual mode1 was developed to elaborate a number of determinants that are theoretically assumed to affect parenting on child development. As a survey, the research relied on the questionnaire as one and only the main instrument of observation. Some statistical analysis techniques were applied to describe and analysis findings of the research.

Abstrak: The decreasing values of kindness among school-age children could be caused by their low conscience and self-control. The aims of this study was to analyze social capital within family, parental acceptance-rejection, and its influence on the character of conscience and self control of the school-age children. Samples frames of this research were the family with the first child is in school-age (10-12 years) who lived in the Situ Gede Village. This research involved 50 samples was randomly taken and interviewed by the questionnaire. The level of social capital within family was measured by instrument that was adopted from Coleman and Hoffer (1987), parenting style measured by Parental Accetance-Rejection Questionnaire (PARQ), the characters was measured by adopted questionnaire from Borba (2001). The results showed that longer father’s formal education is significant correlated with higher character of conscience and self control of the child. Meanwhile, longer mother’s formal education is significant correlated with higher child’s self control and lower father’s violent behavior. Longer age differences between paternal age is significant correlated with lower parental’s neglect behaviour. Characters of conscience and self control correlated with the level of parental closeness, father’s affective behavior, and parental rejection. Regression analysis showed that the characters of conscience and self control of the child are influenced by father's formal education, social capital within family, and parental rejection.

Judul: Perbaikan Proses Pemurnian Gliserol Hasil Samping Industri Biodiesel Menggunakan Distilasi Vakum
Abstrak: Gliserol dari hasil samping industri biodiesel minyak sawit setiap tahun jumlahnya kian meningkat. Gliserol tersebut umumnya hanya memiliki kadar gliserol 40-50% karena masih banyak mengandung pengotor berupa sisa metanol, sisa katalis, asam lemak, air, maupun bahan pengotor lainnya sehingga perlu ditingkatkan kemurniannya agar dapat digunakan di berbagai industri dan meningkatkan nilai jualnya. Salah satu cara yang digunakan untuk memurnikannya adalah dengan penambahan asam fosfat yang dapat meningkatkan kadar gliserol dari 47% menjadi 83%. Penelitian ini bertujuan untuk mendapatkan kondisi proses pemurnian gliserol (±80%) menggunakan metode distilasi vakum untuk menghasilkan gliserol dengan kadar lebih tinggi (±90%). Kondisi terbaik proses pemurnian gliserol melalui metode distilasi vakum adalah pada suhu 90-95°C dan tekanan 15 InHg (0,51 Bar) dengan kecepatan pengadukan 300 rpm selama 2 jam. Kondisi tersebut menghasilkan gliserol dengan kadar gliserol 94,19%, kadar air 0,01%, kadar abu 2,96%, kadar MONG 2,84%, densitas 1,261 gr/cm3, specific gravity 1,264, viskositas 214 cP, viskositas kinematis (40°C) 106 cSt, warna kuning kecoklatan, pH 6,2, bilangan asam 3,88 mg KOH/g sampel, titik didih 110°C, titik nyala >140°C, titik tuang -30°C, dan titik awan -21°C. Hasil ini menunjukkan bahwa suhu yang digunakan pada proses distilasi vakum telah memberikan pengaruh yang signifikan terhadap karakteristik gliserol murni yang dihasilkan.
