Abstract:This research was conducted in order to determine or to re-examine the performances of broiler chickens fed ration containing cinnamon bark powder (Cinnamomum burmannii). Eighty of CP 707 broiler chickens aged of 2 weeks…
ks were used and kept until 6 weeks old. Completely Randomized Design with 5 treatments and 4 replications each treatment was used in this study; the treatments used were, T0= 100% basal ration without cinnamon bark powder (CBP), T1= 99.5% basal ration + 0.5% CBP, T2= 99% basal ration + 1% CBP, T3= 98.5% basal ration + 1.5 % CBP, and T4= 98% basal ration + 2% CBP. The measurements taken were feed consumption, weight gain, feed conversion, and final body weight. The results of analysis of variance (ANOVA) and Duncan test showed that, giving cinnamon bark powder up to 2% in the ration had an effect on CP 707 broiler chickens aged 2-6 weeks; had a very significantly different effect (P<0.01) on body weight gained and so, on final body weight; and significantly different (P <0.05) on feed conversion, but not on feed consumption. In this study, the higher the level of CBP in the ration, the weight gained and final body weight decreased but feed conversion increased. Based on the results of the analysis and discussion, it can be concluded that giving cinnamon bark powder as a natural feed additive up to 2% in the feed did not improve the performance of CP 707 broiler chickens, because of weight gained and final body weight of the chickens decreased, while, feed conversion increased, which means that, economically it was not getting better.
Abstract:Obesity in mothers is a major worldwide health issue that significantly raises the need for obstetric procedures, especially cesarean sections. Numerous difficulties for both mothers and newborns have been linked to elevated…
ated pre-pregnancy and gestational body mass indexes (BMI). The purpose of this study is to characterize the distribution of delivery methods among pregnant women who are obese at Dr. H. Abdul Moeloek Regional Hospital in Lampung Province, Indonesia. Total sampling was used to perform a quantitative, descriptive retrospective analysis. 58 pregnant women with a BMI of 30 kg/m² or above who gave birth between 2017 and 2023 were included. SPSS version 27.0 was utilized for data analysis. Findings out of the 58 instances that could be analyzed, 69.0% of obese pregnant women gave delivery via cesarean section, 27.6% gave birth spontaneous vaginally, and 3.4% had a vacuum induction. The majority (31.0%) were between the ages of 35 and 39, and 77.6% were multiparous. The type of delivery was found to be strongly influenced by maternal age, parity, and obesity. Being obese greatly raises the risk of having a cesarean section, especially for older and multiparous women. Reducing needless cesarean rates and improving mother and newborn outcomes may be possible with early treatments such as lifestyle modification education, prenatal counseling, and BMI-based risk assessment.

long-term blood glucose levels measured by Hemoglobin A1c (HbA1c). This study aimed to explore the relationship between BMI and HbA1c levels in patients at Prima Medika General Hospital, Denpasar. A cross-sectional analytic observational design was employed, involving 30 purposively selected respondents. BMI was calculated from weight and height measurements, while HbA1c levels were assessed using the immunoturbidimetric method. Results showed an even distribution of respondents in the normal and overweight BMI categories (each 46.5%), while 50% had HbA1c levels >8%. However, Pearson correlation analysis indicated no statistically significant relationship between BMI and HbA1c levels (p=0.982; r=-0.004). The study concludes that BMI does not have a linear correlation with HbA1c levels. Other factors such as type and duration of therapy, disease progression, and patient adherence may play a greater role in influencing glycemic control and should be further investigated.

rue experiment design method. The sample in this study was 14 female athletes. The instrument in this study was a 10-second sickle kick speed test with 3 trials and the best value was taken. Data analysis and testing of the research hypothesis used the t-test analysis technique (t-test) with a significance level of α = 0.05. The results of the study showed that: (1) there was an increase in the speed of the sickle kick after athletes followed a training program using rubber weights with an average value of 13.71 in the pre-test and increased by 6.72 or 7% to 20.43 in the post-test. The statistical results showed that the sig-2 tailed value was 0.000 ≤ 0.05. (2) there is an increase in the speed of the sickle kick after the athlete follows a training program without rubber weights with an average value of 13.43 in the pre-test increasing by 5% to 18.43 in the post-test. With statistical results showing that the sig-2 tailed value is 0.000 ≤ 0.05. (3) there is an increase in kick speed between training using rubber weights and without weights with a sig-2 tailed value of 0.013 ≤ 0.05. It can be concluded that training using rubber weights is more effective in increasing the speed of the sickle kick compared to training without rubber weights in the Pen-cak Silat PSHT Ranting Tanah Putih Tanjung Melawan.
Abstract:This study aimed to evaluate the suitability of the coastal waters of Sungai Bakau, Kumai District, as an alternative site for sea cucumber (Holothuria scabra) aquaculture. Water quality parameters, including temperature,…
, salinity, and pH, were monitored, along with the growth performance of sea cucumbers in terms of body weight and length during the cultivation period. The results showed water temperatures ranging from 28–31°C, pH values between 8.3–8.7, and an average salinity of 20.5 ppt. Although the salinity was slightly below the optimal range (28–32 ppt), the sea cucumbers demonstrated positive growth. Final measurements indicated an increase in body weight from 10–20 grams to an average of 0.29 kg, and in body length up to 16.7 cm over approximately three months of cultivation. These findings suggest that the coastal waters of Sungai Bakau have potential for sea cucumber aquaculture development, with some adjustments needed to optimize salinity conditions.

lationship between the consumption of sugar-sweetened beverages and the incidence of overweight among adolescents at SMP Negeri 28 Surabaya. This study employed an analytical observational design with a cross-sectional approach. A total of 164 respondents were selected using proportional random sampling. Data on sugar-sweetened beverage consumption were collected using a Food Frequency Questionnaire (FFQ), while nutritional status was assessed using Body Mass Index-for-Age (BMI-for-Age). Data were analyzed using the Chi-square test. The results showed a significant association between the consumption of sweetened tea (p = 0.023) and carbonated soft drinks (p = 0.000) with overweight, whereas the consumption of coffee, bubble tea, sweetened milk, isotonic drinks, syrup, and yogurt was not significantly associated with overweight (p > 0.05). It can be concluded that frequent consumption of sweetened tea and carbonated soft drinks is associated with an increased risk of overweight among adolescents. Therefore, nutrition education and limiting the consumption of sugar-sweetened beverages are recommended as preventive strategies to reduce overweight among adolescents.
