Judul: Hubungan Empati dan Kecerdasan pada Mahasiswa  Sarjana di Indonesia
Abstrak: Empathy is the ability to understand the feelings and emotions of others, which is important for social interaction in humans. Empathy was predicted can be influenced by the intelligence because individuals with high intelligence are better at understanding and interpreting situational cues. So far, few studies have directly explained the correlation between empathy and intelligence in undergraduate students, but the results are inconsistent and imply that some demographic and cultural backgrounds affect the results. In addition, the relationship between empathy and intelligence of undergraduate students in Indonesia has not been known yet. Therefore, this study aimed to determine the relationship between empathy and intelligence of undergraduate students in Indonesia. This research was conducted using an online platform, with a total of 316 undergraduate students who participated in this research. Each respondent filled out a questionnaire consisting of demographic data, the Interpersonal Reactivity Index (IRI) to assess self-report empathy, and their intelligence using the Baddeley Reasoning Test (BRT). This study showed that undergraduate students in Indonesia have high self-report empathy (Mean = 74.09) and intelligence scores (Mean = 20.58). However, the correlation between empathy and intelligence has no significant correlation (R = –0.017, p-value = 0.76). Thus, it implies that intelligence is not the variable that affects empathy., Empati adalah kemampuan untuk memahami perasaan dan emosi orang lain, yang penting untuk interaksi sosial pada manusia. Empati diprediksi dapat dipengaruhi oleh kecerdasan karena individu dengan kecerdasan tinggi lebih baik dalam memahami dan menginterpretasikan isyarat situasional. Sejauh ini, beberapa penelitian menjelaskan korelasi antara empati dan kecerdasan pada mahasiswa sarjana, tetapi hasilnya tidak konsisten dan menunjukkan bahwa beberapa latar belakang demografi dan budaya mempengaruhi hasil penelitian. Selain itu, hubungan empati dengan kecerdasan mahasiswa sarjana di Indonesia belum diketahui. Oleh karena itu, penelitian ini bertujuan untuk mengetahui hubungan empati dengan kecerdasan mahasiswa sarjana di Indonesia. Penelitian ini dilakukan dengan menggunakan platform online, dengan jumlah mahasiswa sarjana sebanyak 316 orang. Setiap responden mengisi kuesioner yang terdiri dari data demografi, Interpersonal Reactivity Index (IRI) untuk menilai empati laporan diri, dan kecerdasan mereka menggunakan Baddeley Reasoning Test (BRT). Penelitian ini menunjukkan bahwa mahasiswa sarjana di Indonesia memiliki skor tinggi pada empati yang dilaporkan diri sendiri (Mean = 74.09) dan skor kecerdasan (Mean = 20.58). Namun korelasi antara empati dan kecerdasan tidak memiliki korelasi yang signifikan (R = –0,017, p-value = 0.76). Dengan demikian, menyiratkan bahwa kecerdasan bukanlah variabel yang mempengaruhi empati.

Judul: Hubungan antara Kecerdasan Cair dan Kreativitas pada Mahasiswa di Indonesia
Abstrak: Kecerdasan cair adalah kemampuan untuk berpikir secara logis dan abstrak. Kecerdasan cair memiliki korelasi positif dengan kreativitas. Kreativitas adalah kemampuan individu untuk menemukan dan mengembangkan ide-ide baru. Penelitian sebelumnya telah menunjukkan hubungan antara kecerdasan cair yang tinggi diikuti dengan peningkatan kreativitas dalam otak. Kecerdasan cair dan kreativitas juga berperan dalam pemecahan masalah dan beradaptasi dengan perubahan. Saat ini, belum ada data yang tersedia tentang hubungan antara kecerdasan cair dan kreativitas di Indonesia. Penelitian ini bertujuan untuk mengeksplorasi hubungan antara kecerdasan cair dan kreativitas di antara mahasiswa Indonesia. Studi ini dilakukan menggunakan kuesioner dan platform daring dengan sampel 224 mahasiswa di Indonesia. Partisipan menjawab kuesioner yang terdiri dari data demografis dan Adjective Check List (ACL) untuk mengukur kreativitas. Selain itu, partisipan secara bergantian menyelesaikan Baddeley Reasoning Test (BRT) untuk mengukur kecerdasan cair. Hasil studi menunjukkan bahwa mahasiswa Indonesia memiliki skor rata-rata 22,17 untuk kecerdasan cair dan 1,01 untuk kreativitas. Namun, tidak ada korelasi signifikan antara kecerdasan cair dan kreativitas (R = 0,043, nilai p = 0,53). Hal ini menunjukkan bahwa kategorisasi kecerdasan cair tidak semata-mata menentukan potensi kreativitas seseorang., Fluid intelligence is the ability to think logically and abstractly. Fluid intelligence has a positive correlation with creativity. Creativity is an individual’s ability to discover and develop new ideas. Previous research has shown a relationship between high fluid intelligence and increased creativity in the brain. Fluid intelligence and creativity also play a role in problem-solving and adapting to changes. Currently, there is no available data on the relationship between fluid intelligence and creativity in Indonesia. This research aims to explore the relationship between fluid intelligence and creativity among Indonesian students. The study was conducted using questionnaires and an online platform with a sample of 224 students in Indonesia. Participants answered a questionnaire comprising demographic data and the Adjective Check List (ACL) to measure creativity. Additionally, participants took turns completing the Baddeley Reasoning Test (BRT) to measure fluid intelligence. The results of the study showed that Indonesian students had an average score of 22.17 for fluid intelligence and 1.01 for creativity. However, there was no significant correlation between fluid intelligence and creativity (R = 0.043, p-value = 0.53). This indicates that the categorization of fluid intelligence does not solely determine an individual's creative potential.

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.
