Judul: The Influence of Parental Attachment, Loneliness and Escapism Behavior on Binge-watching among College Students
Abstrak: Saat ini banyak terjadi fenomena binge-watching di kalangan mahasiswa yang dapat berdampak negatif pada kesehatan fisik dan psikologis individu. Penelitian ini secara umum bertujuan untuk menganalisis pengaruh kelekatan dengan orang tua, kesepian dan perilaku eskapisme terhadap binge-watching pada mahasiswa. Penelitian ini menggunakan desain eksplanatori dengan metode survei online serta melibatkan 234 mahasiswa di Jawa Barat yang dipilih menggunakan teknik purposive sampling. Analisis data menggunakan uji deskriptif, korelasi, dan Structural Equation Modeling (SEM) menggunakan software SPSS dan SmartPLS. Hasil penelitian menunjukkan bahwa kelekatan berhubungan dengan jenis kelamin binge-watching berhubungan positif dengan usia dan berhubungan negatif dengan tingkat pendidikan orang tua, dan perilaku eskapisme berhubungan positif dengan usia. Sementara itu, hasil penelitian juga menunjukkan kelekatan dengan orang tua berpengaruh negatif pada kesepian yang menyebabkan individu melakukan perilaku eskapisme melalui binge-watching.

Judul: Influence of Parent Attachment, Self-Regulation, and Intensity of Playing Online Game toward Student Engagement
Abstrak: Keterlibatan mahasiswa dalam pembelajaran merupakan faktor keberhasilan akademik. Keterlibatan mahasiswa dalam pembelajaran mampu mengatasi kebosanan dalam belajar terlebih saat pembelajaran daring yang sedang diterapkan ataupun permasalahan lain seperti game online, permainan yang sangat disukai oleh mahasiswa. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik individu, karakteristik keluarga, kelekatan dengan orang tua, regulasi diri, dan intensitas bermain game online terhadap keterlibatan mahasiswa dalam pembelajaran. Penelitian ini menggunakan desain explanatory dengan melibatkan 220 mahasiswa sarjana. Penelitian berlokasi di Institut Pertanian Bogor dan pengambilan contoh dilakukan secara purposive. Hasil penelitian menunjukkan bahwa lebih dari separuh mahasiswa memiliki kelekatan yang sedang pada ibu dan rendah pada ayah, serta memiliki regulasi diri yang sedang. Hampir separuh mahasiswa memiliki intensitas bermain game online yang sangat tinggi dan lebih dari separuh mahasiswa memiliki keterlibatan dalam pembelajaran yang rendah. Hasil uji regresi menunjukkan besar keluarga, kelekatan dengan orang tua, dan regulasi diri berpengaruh pada keterlibatan mahasiswa dalam pembelajaran. Berdasarkan hasil penelitian keterlibatan mahasiswa dalam pembelajaran berkatagori rendah, maka peran kelekatan dengan orang tua dan regulasi disi sangat dibuutuhkan untuk meningkatkan keterlibatan mahasiswa dalam pembelajaran., Student engagement is an academic success factor. Student engagement overcome boredom at study especially at online classes or any other cases like game online, students like the most. This study aims to analyze the influence of individual characteristics, family characteristics, parent attachment, self-regulation, and the intensity of playing online game toward engagement on learning. This study used an explanatory design by involving 220 undergraduate students of IPB University. The research was located at the IPB University and the sampling was done purposively. The results showed that more than half of the students had moderate attachment to parents and had moderate self-regulation. Nearly half of students have a very high intensity of playing online games and have low student engagement on learning. The results of the influence test showed that family size, parent attachment and self-regulation had an effect on student engagement on learning. Based on the study result in the low category of student engagement, the role of parent attachment and self-regulation is needed to incrase student engagement.

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.
