This study aimed to investigate the potential of plastic waste, specifically bubble wrap and packaging plastic, as a fuel source through pyrolysis process. The samples were analyzed using FTIR and GC-MS. The results showed that both samples contained alkanes and alkenes, with hydrocarbon fractions like those found in gasoline, kerosene, and diesel fuel. The pyrolysis process resulted in hydrocarbon fractions ranging from light to heavy fractions. The bubble wrap sample showed the highest percentage of hydrocarbon fraction in the kerosene range (C10-C13), with an area of 19.23%. In contrast, the packaging plastic sample showed the highest percentage of hydrocarbon fraction in the diesel range (C14-C20), with an area percentage of 19.67%. The calorific value of the pyrolysis products was also determined, with the bubble wrap sample having a higher value than that of gasoline, while the packaging plastic sample had a value close to that of kerosene. The results of this study suggest that plastic waste has the potential to be converted into fuel, which can contribute to sustainable development by reducing dependence on fossil fuels and reducing plastic waste. However, further refinement of the pyrolysis products is needed to meet commercial fuel standards.
Media sosial saat ini telah masuk kedalam sendi-sendi kehidupan manusia, jika kita perhatikan hampir seluruh masyarakat menggunakannya baik dari kalangan dewasa, remaja hingga anak-anak. Adapun contoh yang diambil dalam penelitian ini adalah media sosial instagram. Karena dinilai dapat mempengaruhi pola perilaku penggunanya khususnya remaja. Tujuan dari penelitian ini untuk mengetahui hubungan antara media sosial instagram dengan interkasi sosial di sekolah siswa kelas VIII SMP Negeri 14 Bogor. Penelitian ini menggunakan metode kuantitatif jenis kolerasional. Pengumpulan data dalam bentuk kuisioner yang diberikan kepada 72 responden yang merupakan siswa kelas VIII SMP Negeri 14 Bogor. Pengambilan sampel dalam penelitian ini menggunakan teknik probability sampling, dan di analisis menggunakan uji kolerasional menggunakan program IBM SPSS versi 25. Hasil dari penelitian ini didapat nilai koefisien kolerasi sebesar 0,458, berada pada rentang 0,40-0,70 yaitu bermakna terdapat hubungan antara media sosial instagram dengan interaksi sosial di sekolah siswa kelas VIII SMP Negeri 14.
Penelitian ini bertujuan untuk mendeskripsikan implikasi pola asuh orangtua terhadap kecerdasan emosional anak usia dini. Jenis penelitian ini adalah kualitiatif deskriptif dengan Teknik pengumpulan data wawancara, observasi, dan dokumentasi. Sumber data dalam penelitian ini adalah orang tua TK PGRI 1 Taddan Camplong Kabupaten Sampang, anak usia dini, kepala sekolah serta Guru TK. Teknik analisis data menggunakan reduksi data, display data, serta verifikasi data. Sedangkan teknik pengecekan datanya melalui perpanjangan keikutsertaan, ketekunan pengamatan, triangulasi. Hasil penelitian menunjukkan bahwa orangtua berperan penting dalam mendidik atau mengasuh anak. Pola asuh yang diterapkan orangtua terhadap anaknya di TK ini adalah: demokratis, orang tua yang berambisi, orang tua yang membandingkan anaknya dengan anak lain, dan orang tua yang otoriter. Implikasi pola asuh orangtua terhadap kecerdasan emosional anak usia dini, meliputi: Cenderung tidak ramah dan pemalu, kurang pengendalian diri terhadap emosionalnya, kurang empati, sulit beradaptasi dengan orang lain, kurang percaya diri, dan penakut.
The problem of plastic waste has recently attracted more attention due to the non- biodegradable of plastic. The thermochemical method through pyrolysis is one of the most effective methods used in processing of plastic waste into fuel. Here we report on the pyrolysis of plastic packaging using a batch pyrolysis reactor at 430 °C. The derived liquid has a compound distribution starting from the light aliphatic compounds. In addition, this liquid has a gross calorific value of 11090.9 kcal/kg. This value is in the range of the gross calorific value of commercial gasoline. Thus, the pyrolysis process of plastic packaging has the potential to become a fuel.
