Berdasarkan Riset Kesehatan Dasar Tahun 2013 dan 2018, menunjukkan adanya peningkatan prevalensi gizi lebih dan obesitas di provinsi Riau yaitu dari 3,1% menjadi 11,6%. Tujuan penelitian ini adalah untuk menganalisis faktor-faktor yang berhubungan dengan kejadian gizi lebih/obesitas pada remaja siswa SMA Negeri di Kota Pekanbaru Tahun 2023. Jenis penelitian adalah analitik kuantitatif dengan desain cross sectional. Penelitian dilakukan pada bulan Mei-Juni 2023. Sampel adalah siswa SMAN kelas X dan XI di tiga SMAN di Kota Pekanbaru, yaitu SMAN 4, SMAN 6, dan SMAN 12. Pengambilan sampel dilakukan dengan cara purposive sampling. Variabel independen adalah jenis kelamin, pengetahuan remaja, pendidikan orang tua, pekerjaan orang tua, uang saku, status kegemukan orang tua, aktivitas fisik, kualitas tidur, konsumsi makanan cepat saji dan konsumsi makanan manis. Variabel dependen adalah gizi lebih/obesitas. Analisis data dilakukan secara univariat, bivariat dan multivariat. Hasil analisis menunjukkan bahwa variabel yang dominan berhubungan dengan gizi/obesitas adalah status kegemukan orang tua (OR=3,12; 95% CI: 1,25-7,83). Remaja dengan orang tua gemuk/obesitas lebih berisiko 3 kali mengalami gizi lebih/obesitas dibandingkan dengan remaja yang tidak memiliki orang tua gemuk/obesitas. Variabel lain yang berhubungan adalah pengetahuan siswa (OR=2,62; 95% CI: 1,27-5,39) dan kebiasaan makanan manis (OR=2,34; 95% CI:1,04-5,27). ......Based on the 2013 and 2018 Basic Health Research, there was an increase in the prevalence of overnutrition and obesity in Riau province from 3.1% to 11.6%. This study aimed to analyse the factors associated with the incidence of overeight/obesity in adolescent students of public high schools in Pekanbaru City in 2023. The type of research is quantitative analytic with a cross-sectional design. The research was conducted in May-June 2023. Samples were class X and XI students in three high schools in Pekanbaru City, namely SMAN 4, SMAN 6, and SMAN 12. Sampling was done by purposive sampling. Independent variables were gender, adolescent knowledge, parental education, parental occupation, pocket money, parental obesity status, physical activity, sleep quality, fast food consumption and sweet food consumption. The dependent variable was overweight/obesity. Data were analysed univariately, bivariate and multivariate. The results showed that the dominant variable associated with overweight/obesity was parental obesity status (OR=3.12; 95% CI: 1.25-7.83). Adolescents with obese parents were three times more likely to experience overweight/obesity compared to adolescents who did not have obese parents. Other associated variables were student knowledge (OR=2.62; 95% CI: 1.27-5.39) and sweet food habits (OR=2.34; 95% CI: 1.04-5.27). For this reason, schools are expected to work with the Health Office and Community Health Center to organise counselling or seminars on nutrition and obesity in adolescents; schools can provide healthy canteens by limiting the availability of fast food and sugary drinks

Metal Organic Framework (MOF) meupakan suatu material yang merupakan gabungan antara material organik dan anorganik yang berpusat pada ion logam positif dan dikelilingi oleh molekul-molekul ligand organik. Pada penelitian ini, penulis melakukan suatu sintesis MOF menggunakan ion logam zinc (Zn) dengan ligan organik glutamic acid (Zinc Glutamate MOF) dan menginvestigasi kinerjanya dalam mengadsorpsi karbondioksida. kemudian penulis juga akan meneliti mengenai dampak lingkungan yang mungkin ditimbulkan pada proses produksi Zinc Glutamate MOF menggunakan metode LCA melalui skema pendekatan cradle to gate. Life Cycle Assessment (LCA) merupakan salah satu metode untuk melakukan penilaian atau evaluasi potensi dampak lingkungan dari produk atau jasa pada semua tahap dalam siklus hidup suatu produk. Dalam hal ini, dapat diobservasi beberapa potensi dampak yang ditimbulkan dari setiap proses produksi MOF berdasarkan data input yang diperoleh selama proses produksi MOF, dimulai dari proses pembuatan material precursor hingga pada aplikasi carbon capture. ......Metal Organic Framework (MOF) is a material which is a combination of organic and inorganic materials centered on positive metal ions and surrounded by organic ligand molecules. In this study, the authors carried out a MOF synthesis using zinc metal ion (Zn) with glutamic acid organic ligand (Zinc Glutamate MOF) and investigated its performance in adsorption of carbon dioxide. Furthermore, the author will also examine the environmental impacts that possibly caused from production process of Zinc Glutamate MOF using the LCA method through a cradle to gate approach scheme. Life Cycle Assessment (LCA) is a method for assessing or evaluating the potential environmental impact of a product or service at all stages in the life cycle of a product. In this case, several potential impacts can be observed from each MOF production process based on the input data obtained during the MOF production process, starting from the precursor material manufacturing process to the carbon capture application.

Chlorella vulgaris Buitenzorg cultivation using three bubble column photo bioreactors arranged in series with a volume of 200 mL for 130 hours shows an increase of biomass production of Chlorella vulgaris Buitenzorg up to 1.20 times and a decrease of the ability of CO2 fixation compared to single reactor at a periodic sun illumination cycle. The operation conditions on cultivation are as following: T, 29.0oC; P,1 atm.; UG, 2.40 m/h; CO2, 10%; Benneck medium; and illumination source by Phillip Halogen Lamp 20W /12V/ 50Hz. Other research parameters such as microbial carbon dioxide transferred rate (qco2), CO2 transferred rate (CTR), energy consumption for cellular formation (Ex), and cultural bicarbonate species concentration [HCO3] also give better results on series of reactor.
