Judul: Effectiveness of Daud Fasting on Weight Loss and Body Fat Composition in Young Adults
Abstrak: Kunci utama dalam mengatasi obesitas adalah pembatasan asupan energi dan peningkatan aktivitas fisik. Puasa merupakan salah satu upaya pencegahan obesitas melalui pendekatan diet. Penelitian ini bertujuan menganalisis efektifitas puasa Daud terhadap penurunan berat badan dan komposisi lemak tubuh pada dewasa muda overweight dan obese. Penelitian ini menggunakan desain experimental study dengan melibatkan 39 subjek yang dibagi menjadi 2 kelompok (intervensi dan kontrol). Hasil penelitian menunjukkan kelompok intervensi mengalami penurunan berat badan (-1,7 ± 1,3 kg), IMT (-0,6 ± 0,5 kg/m2), dan level lemak viseral (-0,6 ± 0,5) secara signifikan setelah berpuasa Daud selama 4 minggu. Persentase lemak tubuh kelompok intervensi cenderung menurun (-0,1 ± 0,8%), tetapi tidak signifikan. Tingkat kecukupan energi (p = 0,001), protein (p = 0,002), lemak (p = 0,010), dan karbohidrat (p = 0,000) kelompok intervensi menurun signifikan pada hari puasa dibandingkan hari makan. Tingkat aktivitas fisik antar kelompok tidak berbeda nyata, baik pada hari puasa (p = 0,213) maupun hari makan (p = 0,239). Kelompok intervensi tidak mengalami penurunan aktivitas fisik yang signifikan pada hari puasa dibandingkan dengan hari makan (p = 0,739)., Calorie restriction and increasing physical activity are the main keys in overcoming obesity. Fasting is one of the effort to prevent obesity through a diet approach. This study aims to analyze the effectiveness of Daud fasting on weight loss and body fat composition in overweight and obese young adults. This study used an experimental design involving 39 subjects which divided into 2 groups (intervention and control). Results showed that intervention group lost body weight (-1,7 ± 1,3 kg), BMI (-0,6 ± 0,5 kg/m2), and visceral fat levels (-0,6 ± 0,5) significantly after 4 weeks of Daud fasting. Body fat percentage in intervention group tended to decrease (-0,1 ± 0,8%), but not significant. The adequacy level of energy (p = 0,001), protein (p = 0,002), fat (p = 0,010), and carbohydrates (p = 0,000) in intervention group decreased significantly on fasting day, compared to feasting day. Physical activity level between groups was not significantly different, both on fasting day (p = 0,213) and feasting day (p = 0,239). The physical activity of intervention group did not decrease significantly on fasting day, compared to feasting day (p = 0,739).

Judul: Efikasi Puasa Ramadan terhadap Penurunan Berat Badan dan Indeks Massa Tubuh pada Dewasa Muda
Abstrak: Tujuan dari penelitian ini adalah menganalisis efikasi puasa Ramadan terhadap penurunan berat badan dan indeks massa tubuh pada dewasa muda. Desain cohort prospective study digunakan untuk penelitian ini, sebanyak 98 orang dewasa muda (51 laki-laki) dilibatkan dalam penelitian ini. Data yang dikumpulkan meliputi tinggi badan, IMT, komposisi tubuh, konsumsi pangan, dan aktivitas fisik sebelum dan saat puasa Ramadan. Hasil dari penelitian ini diketahui bahwa puasa Ramadan efektif menurunkan berat badan, IMT, massa tubuh tanpa lemak dan air, massa lemak, dan air tubuh (p<0.01) di akhir puasa Ramadan. Tingkat konsumsi energi dan lemak menurun signifikan selama puasa Ramadan pada subjek perempuan. Penurunan berat badan dipengaruhi oleh jenis kelamin, perubahan tingkat konsumsi energi, dan perubahan tingkat aktivitas fisik.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
