Abstrak: Kesejahteraan subjektif dinilai sebagai salah satu ukuran saintifik untuk menggambarkan kebahagiaan dan kualitas hidup seseorang. Penelitian ini bertujuan untuk menganalisis pengaruh praktik pengasuhan dan karakter terhadap kesejahteraan subjektif remaja. Penelitian ini menggunakan metode eksplanatori dan dilakukan di Kota Bekasi yang dipilih secara purposive. Responden berjumlah 213 remaja yang merupakan siswa kelas XI SMA/SMK. Data primer diperoleh melalui teknik self-administered menggunakan kuesioner terstruktur. Data yang digunakan meliputi karakteristik remaja (usia dan jenis kelamin), karakteristik keluarga (usia orang tua, pendidikan orang tua, pekerjaan orang tua, dan besar keluarga), praktik pengasuhan, karakter, dan kesejahteraan subjektif remaja. Hasil penelitian menunjukkan indeks praktik pengasuhan dan kesejahteraan subjektif terkategori rendah, sementara indeks karakter terkategori sedang. Hasil uji hubungan menemukan bahwa remaja perempuan cenderung menerima praktik pengasuhan yang lebih baik. Selain itu ditemukan pula hubungan signifikan antara praktik pengasuhan, karakter, dan kesejahteraan subjektif. Hasil uji regresi menemukan bahwa praktik pengasuhan orang tua dan karakter remaja secara signifikan memberikan pengaruh paling nyata terhadap kesejahteraan subjektif remaja., Subjective well-being is considered as one of scientific measures to represent one’s happiness and quality of life.

Judul: Karakterisasi dan Kloning Fragmen Gen Protein Membran Luar (OMP) Candidatus liberibacter
Abstrak: Outer membrane protein (OMP) gene is a potential gene to identify Candidatus liberibacter, patogent for CVPD (Citrus Vein Phloem Degeneration) disease in citrus plant. The objectives of this research are to clone and to characterize OMP gene fragment of Indonesian isolate C.liberibacter. Characterization based on nucleotide and amino acid. Cloning of DNA fragment of C.liberibacter OMP gene which isolated from infectious citrus, was ligated to pGEM-T Easy vector and was transformed to E.coli DH5α. DNA isolation showed fragment is 696 bp. Cloning gene fragment showed by growth two single colonies and 696 pb gene fragment from colony PCR and plasmid PCR. Characterization based on nucleotide showed OMP gene 99% homolog with C.liberibacter asiaticus. While amino acid characterization showed relative with outer membrane protein in C.liberibacter africanus, C.liberibacter americanus, C.liberibacter solanacearum, C.liberibacter crescens, and Rhizobium etli. The result of amino acid characterization showed there are conserved protein domain.
