AbstrakPendahuluan: Sejumlah penelitian menunjukkan hubungan antara konsumsi lemak dengan indeks massa tubuh dan komposisi tubuh. Penelitian ini bertujuan untuk mengetahui hubungan antara konsumsi harian lemak total, asam lemak tak jenuh ganda (PUFA) dan kolesterol total dengan beberapa paramater gizi.Metode: Penelitian ini merupakan studi cross-sectional, dengan 102 subjek. Pemeriksaan yang dilakukan adalah tinggi badan, berat badan, indeks massa tubuh dan pengukuran komposisi tubuh menggunakan timbangan komposisi tubuh Omron® HBF-212. Analisis konsumsi lemak total, asam lemak tak jenuh ganda dan kolesterol total menggunakan Software nutrisurvey 2007. Uji korelasi yang digunakan adalah Spearman Rho dengan menggunakan SpSS 21.Hasil: Konsumsi lemak total tidak berhubungan dengan indeks massa tubuh, massa lemak total, dan massa lemak visceral. Konsumsi PUFA berhubungan secara negatif dengan indeks massa tubuh (p <0,014, -0,24) dan massa lemak total (p <0,001, -0,326), sedangkan konsumsi total kolesterol total berhubugan secara negatif dengan indeks massa tubuh (p <0,019, -0,23), dan massa lemak total (p <0,001, -0,337).Kesimpulan: Ada hubungan antara konsumsi lemak dengan indeks massa tubuh dan komposisi tubuh. AbstractIntroduction: Studies showed some relation between fat consumption with body mass index and body composition. We conducted a study to investigate relationships between daily consumption of total fat, polyunsaturated fatty acid (PUFA) and total cholesterol with some nutritional parameters. Methods:This was cross-sectional study, with 102 subjects. The study was examined height, body weight, body mass index and body composition measurements using the Omron® HBF-212 body composition monitor. There was nutrisurvey 2007 to measure total fat, polyunsaturated fatty acid and total cholesterol consumption. We analyzed the correlation by using SpSS 21 (Spearman Rho) Results: Total fat consumption was not related to body mass index, total fat mass, and visceral fat mass. PUFA consumption was negatively associated with body mass index (p <0.014, -0.24) and total fat mass (p <0.001, -0.326), while consumption of total cholesterol was negatively associated with body mass index (p <0.019, -0.23), and total fat mass (p <0.001, -0.337) Conclusion:There was a relation between fat consumption with body mass index and body composition.

This experiment was conducted to study the effects of different feed forms on small intestine histomorphology of broiler chicken at 35 days of age. A total of 72 unsexed New-Lohman broiler chicks was placed into three treatments with three replications of 8 chicks. Feed treatments were given in two phases: 0-21 days and 22-35 days. The treatments group consisted of T1 (0-21 days: mash form, 22-35 days: mash form, defined as mash: mash), T2 and T3 were crumble:crumble and crumble: pellet form, respectively. Parameters evaluated were small intestine (duodenum, jejunum, and ileum) histomorphology (villus height, villus width, crypt depth, and villus height to crypt depth ratio), as well as their weight (g) and length (cm). Data were analyzed using analysis of variance followed by Duncan’s Multiple Range Test. Villus height, crypt depth, and villus height to crypt depth ratio in the duodenum and jejunum of T1 were lower than T2 and T3. The length and weight of duodenum and jejunum of T2 and T3 were higher than T1. It can be concluded that broilers fed by crumble: crumble and crumble: pellet form could improve the development of small intestine as well as its histomorphology.

Many tropical agricultural products belong to climacteric group which need more attention to be able to extend or maintain their shelf life during storage. One of the most important phenomenon of climacteric produce is about the respiration rate of that produce. The following research was intended to investigate the rate of respiration of tropical climacteric products under various treatments including low temperature and the type of products. This research had developed respirometer device made from glass and thick plastic jar equipped with some needed sensing devices such as air temperature and humidity, product temperature sensing devices, and a tap for O2 and CO2 measurement. The respiration rate of banana, guava, and mango was succeded measured by using a closed system method. It was found that storage temperature, fruit type, and interaction between them were significantly affect the respiration rate. The changes in gas composition inside the respirometer were found to vary for each fruit studied. This could be referred to an internal composition for every fruit was different. The fastest rate of O2 consumption and CO2 evolution belong to banana and mango, respectively. The effect of temperature on respiration rate could be modeled using Arrhenius equation with a satisfactory results.
