Abstract

Artikel ini bertujuan untuk mengetahui bagaimana pengaruh uang saku bulanan yang diterima mahasiswa setiap bulan dari keluarganya terhadap gaya hidup dan perilaku konsumsi makanan yang tidak sehat pada Mahasiswa di Universitas Pendidikan Indonesia. Metode yang digunakan dalam penelitian adalah metode deskriptif dengan pendekatan kualitatif dan teknik pengumpulan data dilakukan dengan observasi menggunakan kuesioner dengan google form berjumlah 7 soal, yang terdiri dari 1 soal terbuka dan 6 soal diantaranya tertutup. Teknik menganalisis data dalam penelitian ini dilakukan melalui pendekatan analisis data yang mencakup tiga kegiatan secara bersamaan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian ini menunjukkan bahwa uang saku bulanan memiliki pengaruh positif dan signifikan terhadap gaya hidup mahasiswa. Gaya hidup yang lebih tinggi disebabkan oleh uang saku bulanan mempengaruhi perilaku konsumsi makanan tidak sehat pada mahasiswa. Hasil penelitian ini sejalan dengan penelitian sebelumnya yang menunjukkan bahwa uang saku juga memiliki pengaruh terhadap perilaku konsumtif mahasiswa. Diharapkan artikel ini dapat digunakan referensi untuk meningkatkan kesadaran mahasiswa tentang pentingnya mengelola uang saku dengan baik dan memilih makanan yang seimbang dan sehat untuk meningkatkan kesehatan mereka.

Abstract

The research aims to identify the effect of using Spirit Fingers from Webtoon application in improving students’ vocabulary mastery in eleventh-grade students. This research was a pre-experimental research design. The population of the study was Eleventh-grade students at SMA N 2 Sungai Limau. The population consists of 204 students who are classified into six classes. XI FASE F3 was selected as a sample through the cluster random sampling method. The total number of students in this class was 33 students. The research was conducted in seven meetings. The researcher used pre-tests and post-tests to collect the data. The instrument of this research was a vocabulary test. There were 37 multiple-choice questions. The result of the study shows that the significant value of the two-tailed paired sample t-test was less than 0.05. This means that this research’s null hypothesis (H0) was rejected, and the alternative hypothesis (H1) was accepted. It proved that using the Spirit Fingers story from the Webtoon application significantly improved students' vocabulary mastery at SMA N 2 Sungai Limau.

Abstract

Wastewater originating from household, industrial, and public places that contains materials can endanger human life and living things and disrupt environmental sustainability. Various methods have recycled domestic wastewater. One is through the photodegradation process utilizing ultraviolet light in the photocatalytic process. Inorganic materials are semiconductors with photocatalyst activity that can absorb photons and simultaneously carry out material interface transformation reactions. The research aimed to determine the effect of adding Fe metal dopants on TiO2 photocatalyst activity in simulated methylene blue and domestic waste treatment. The precursor used was TiO2 P25 Degussa Anatase. Fe dopant was added using the hydrothermal method with variations of 2%, 4%, and 6%. The XRD characterization results show that TiO2 has a high degree of crystallinity, so the overall process of electron diffusion and electron transfer in SSPT is higher to increase its efficiency. SEM-EDX characterization results show that TiO2-Fe particles are scattered in a spherical shape with a size of less than (<)100 nm and tend to agglomerate. Test results of simulated methylene blue (MB) waste with a UV-Vis spectrophotometer at variations in mass, concentration, pH, and time showed that the addition of doping could increase photocatalytic activity and optimum conditions at 6% (F6) were used in the analysis of parameters pH, COD and TSS of domestic wastewater. The pH value increased from 5 to 6, % COD degradation was 59.17%, and TSS was 23.07%. This research showed that TiO2-Fe was effective enough for domestic wastewater treatment.
