Judul: The Influence of Self-Concept and Parent Attachment on Quarter-Life Crisis in Generation Z
Abstrak: Pada masa dewasa awal, seseorang dapat mengalami krisis yang disebut quarter-life crisis. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik individu, karakteristik orang tua, konsep diri, dan kelekatan orang tua terhadap quarter-life crisis pada generasi Z. Desain penelitian yang digunakan adalah penelitian eksplanatori dengan pendekatan kuantitatif. Penelitian ini melibatkan 213 responden yang terbagi menjadi dua kelompok generasi Z yaitu kelompok mahasiswa dan karyawan berusia 18-25 tahun yang berdomisili di daerah Jabodetabek. Hasil uji beda menunjukkan bahwa konsep diri, kelekatan orang tua, dan quarter-life crisis memiliki perbedaan signifikan antara generasi Z yang berprofesi sebagai mahasiswa dan karyawan. Hasil uji hubungan menemukan bahwa konsep diri memiliki hubungan negatif dengan quarter-life crisis, sementara kelekatan orang tua tidak memiliki hubungan dengan quarter-life crisis. Konsep diri juga secara konsisten memengaruhi quarter-life crisis dari hasil uji pengaruh pada penelitian ini., In early adulthood, a person may experience a crisis called a quarter-life crisis. This study aims to analyze the influence of individual characteristics, parental characteristics, self-concept, and parental attachment to the quarter-life crisis in generation Z. The research design used is explanatory research with a quantitative approach. This research involved 213 respondents who were divided into two groups of generation Z, namely groups of college students and employees aged 18-25 years domiciled in the Jabodetabek area. The results of the different test show that self-concept, parental attachment, and quarter-life crisis have significant differences between generation Z who work as college students and employees. The results of the relationship test found that self-concept had a negative relationship with quarter-life crisis, while parental attachment had no relationship with quarter-life crisis. Self-concept also consistently influences the quarter-life crisis from the results of the regression test in this study.

Judul: The Effects of Resilience and Parental Interactions on Quarter-Life Crisis among Early Adults
Abstrak: Setiap periode perkembangan manusia memiliki keunikan tantangan yang berbeda-beda, namun apabila tantangan tersebut tidak dapat diatasi akan menyebabkan munculnya krisis dalam hidup. Krisis pada periode dewasa awal disebut quarter-life crisis. Penelitian ini bertujuan untuk menganalisis hubungan dan pengaruh resiliensi dan interaksi orang tua terhadap quarter-life crisis pada dewasa awal. Penelitian ini menggunakan desain explanatory dengan 266 dewasa awal yang berusia 18-29 tahun di wilayah Jakarta, Bogor, Depok, Tangerang, dan Bekasi (Jabodetabek). Penelitian ini menggunakan teknik voluntary sampling dengan survei dilakukan secara online. Hasil analisis korelasi menunjukkan bahwa resiliensi dan interaksi orang tua dengan anak memiliki hubungan negatif signifikan dengan quarter-life crisis. Hasil analisis regresi menunjukkan bahwa resiliensi dan interaksi orang tua dengan anak memiliki pengaruh negatif signifikan terhadap quarter-life crisis., Each period of human development has unique challenges, but if these challenges cannot be overcome, it will cause crisis in life. The crisis during early adulthood is known as quarter-life crisis. This study aimed to analyze the relationship and the effect of resilience and parental interactions in early adult who experience a quarter-life crisis. The research design was explanatory involving 266 early adults with age ranged 18-29 years old in the areas of Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek). This study employed a voluntary sampling technique using online survey.

Judul: Metil Ester Gondorukem sebagai Kandidat Bahan Bakar Nabati
Abstrak: The objective of this research is to produce ester of rosin distillate using methanol and H2SO4 (pa) as a catalyst. The result showed an optimum yield of methyl ester was 88.5% at an operating condition of 1.2 mL catalyst in 1.5 hours. The infrared spectra showed that carboxyl groups was replaced by C=O ester group, proofing that the rosin distillate was esterified. Furthermore, the gas chromatography-mass spectrometer spectra showed that the resin acids consists of ester derivates of abietic acid, sandaracopimaric acid, dehidroabietic acid, isopimaric acid, palustric acid. Based on SNI 04 -7182-2006, the kinematic viscosity at 40ºC (4.2 mm2/s), cloud point (-18ºC), total sulfur (67 ppm), acid number (0.1 mg-KOH/g), iodine number (12.8%), and total alkyl ester (99.8%), the methyl ester of pine rosin would be feasible to be used as a biodiesel material. The flash point was considered too low for biodiesel, but would be suitable f or biogasoline.
