Abstrak: The objective of this study was to learn and analyze the relationship between the pattern of food consumption, nutritional status, stress level, and health status in Women Participants of Jantung Sehat Gymnastics at Cianjur, West Java. This study used cross-sectional study design. Sampling method used was purposive sampling. Descriptive analysis showed the highest level adequacy of energy 36.6% and the highest level adequacy of protein 48.8%. Nutritional status based on BMI were categorized as overweight. Stress level of sample were categorized as light depression. Systole blood pressure of the sample were categorized as prehypertension and also hypertension stage I, whereas diastole was categorized as hypertension stage II. Casual Plasma Glucose os sample was normal. Osteoarthritis during one week of sample was categorized as no pain. The Pearson and Spearman correlation test showed that nutritional status with nutrient intake, stress level, and nutritional status of the sample had no significant relationship (p>0.05).

Judul: Sintesis Komposit Zeolit/TiO2 dan Aplikasinya sebagai Fotokatalis Pendegradasi Metyhlene Blue
Abstrak: Zeolit disintesis dari limbah kaleng dan foil aluminium sebagai sumber alumina serta kaca air (water glass) sebagai sumber silika yang dikompositkan dengan TiO2 menggunakan metode hidrotermal. Komposit zeolit/TiO2 dengan pemuatan massa TiO2 0%, 2.5%, 5%, 10%, dan 15% dievaluasi kinerjanya dalam fotodegradasi zat warna biru metilena di bawah sinar ultraviolet (UV). Persentase terbaik pemuatan massa TiO2 ke dalam zeolit ialah 2.5% dan 5%. Komposit diamati menggunakan difraksi sinar-X (XRD) dan mikroskop elektron payaran (SEM). Dari data XRD diperoleh pola difraksi yang mirip dengan zeolit tipe NaP1, zeolit tipe X, dan campuran fase TiO2 anatase dan rutil. Pemuatan massa TiO2 tertinggi sebesar 15% yang dikompositkan ke dalam zeolit membentuk zeolit tipe NaP1 yang lebih dominan. Berdasarkan literatur, morfologi TiO2 menyebar pada permukaan zeolit yang mengakibatkan peningkatan pada volume pori. Aktivitas fotodegradasi biru metilena diuji menggunakan spektrofotometer UV-Vis dengan panjang gelombang 665 nm. Hasil fotodegradasi komposit zeolit/TiO2 di bawah lampu UV pada konsentrasi biru metilena sebesar 20 mg/L memperlihatkan 99.43% degradasi.
