Judul: Pengaruh Kelekatan Remaja-Orang Tua, Tekanan Teman Sebaya, dan Konsep Diri terhadap Perilaku Seksual Pranikah Remaja SMK
Abstrak: Perkembangan seksualitas pada remaja menimbulkan tujuan baru yaitu reproduksi (keturunan) yang seringkali membuat remaja mengabaikan risiko. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi perilaku seksual pranikah remaja. Penelitian ini menggunakan desain cross-sectional study yang dilakukan secara purposive pada dua SMK Swasta masing-masing di Kota dan Kabupaten Bogor. Sampel penelitian adalah siswa kelas 10 dan 11 yang pernah atau sedang berpacaran serta memiliki orang tua kandung lengkap sehingga total responden 212 siswa. Hasil penelitian menunjukkan bahwa tidak ditemukan perbedaan signifikan pada kelekatan remaja-orang tua, tekanan teman sebaya, konsep diri, dan perilaku seksual pranikah antara di kota dan kabupaten. Penelitian menunjukkan usia ibu berhubungan positif dengan kelekatan remaja, remaja laki-laki cenderung memiliki kelekatan remaja-orang tua dan tekanan teman sebaya lebih tinggi. Kelekatan remaja-orang tua berpengaruh secara langsung terhadap konsep diri remaja, akan tetapi kelekatan remaja-orang tua tidak berpengaruh terhadap perilaku seksual pranikah. Perilaku seksual pranikah remaja hanya dipengaruhi langsung oleh tekanan teman sebaya., The development of sexuality in adolescents raises a new goal: reproduction (offspring). This often causes adolescents to ignore risks. This study aims to analyze the factors that influence adolescent premarital sexual behavior. It uses a cross-sectional study design conducted purposefully at two private vocational schools in Bogor City and Regency, respectively. The research sample consists of 10th and 11th-grade students who are currently dating, or have been, and have complete biological parents. Therefore, the total number of respondents is 212 students. The results show no significant differences in adolescent-parent attachment, peer pressure, self-concept, and premarital sexual behavior between the city and regency. The study also reveals that maternal age is positively associated with adolescent attachment. It also shows that male adolescents tend to have higher adolescent-parent attachment and peer pressure. Parent-adolescent attachment has a direct effect on adolescent self-concept. However, adolescent-parent attachment has no effect on premarital sexual behavior. Adolescent premarital sexual behavior is only directly influenced by peer pressure.

Judul: The Influence of Parent-Adolescent and Peer Interaction on Premarital Sexual Perception of Adolescent Broken Home
Abstrak: Perceraian di Indonesia terus meningkat mengakibatkan ketidakseimbangan peran dan fungsi keluarga. Ketidakseimbangan tersebut memberikan dampak kepada remaja seperti perilaku seksual pranikah remaja. Tujuan dari penelitian ini adalah untuk mengidentifikasi hubungan dan pengaruh interaksi orang tua-remaja dan interaksi teman sebaya terhadap persepsi seksual pranikah pada remaja dari keluarga broken home. Metode yang digunakan dalam penelitian ini adalah metode purposive sampling dengan pengisian survei secara online. Jumlah sampel penelitian sebanyak 190 remaja yang berasal dari keluarga broken home di daerah Jabodetabek (Jakarta, Bogor, Depok, Tangerang dan Bekasi). Uji hubungan menunjukkan interaksi orang tua-remaja memiliki hubungan yang negatif signifikan terhadap persepsi seksual pranikah remaja dari keluarga broken home. Hasil uji pengaruh menunjukkan interaksi orang tua-remaja berpengaruh negatif signifikan terhadap persepsi seksual pranikah remaja dari keluarga broken home, namun interaksi teman sebaya memiliki pengaruh positif tidak signifikan terhadap persepsi sekual remaja dari keluarga broken home., Divorce in Indonesia continues to increase resulting in an imbalance of family roles and functions. This imbalance has an impact on adolescents such as adolescent premarital sexual behavior. This study aims to identify the correlation and effect of parent-adolescent interaction and peer interaction on premarital sexual perception among adolescents from broken home family. The method used in this study is a purposive sampling method using an online survey. The total research samples were 190 teenagers from broken home families living in the Jabodetabek area (Jakarta, Bogor, Depok, Tangerang and Bekasi). The relationship test showed that the parent-adolescent interaction had a significant negative relationship on the premarital sexual perception of adolescents from broken home families. The results of the influence test showed that the parent adolescent interaction had a significant negative effect on premarital sexual perceptions of adolescents from broken homes, but peer interaction had an insignificant positive effect on sexual perceptions of adolescents from broken homes.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
