"Nawawi Farm" Breeder Group of Nogosari Village is one of the breeder's groups community in Jember Regency which has a focus on layer rooster’s commodity business. Members of this group are approximately 100 breeders. Production of laying hens has a final weight of around 800 g. Meanwhile, feeding during maintenance requires quite a lot of cost. The existence of expenditures made and income generated is unbalanced, of course, become quite serious problems in the world of the livestock business. This is due to the lack of understanding of the Nawawi Farm livestock group regarding the maintenance management of Laying Roosters. Therefore, training and educations are needed regarding the maintenance management of laying hens. The service of the community dedication stage begins with analyzing community needs, training in the management of laying hens, to guiding the maintenance of laying hens in the Nawawi Farm Livestock Group. The main results of the implementation of this service carried out is that all Nawawi Farm breeders can understand the maintenance management of Laying Hens properly and correctly. The service activities that have been carried out can be carried out properly and run smoothly in accordance with the planned activities that have been prepared. This community service activity was well-received by all apparatus of the Nawawi Farm breeder group. The suggestion of this activity is a follow-up activity in the form of training on making rations with the use of local feed ingredients, especially in the face of the new normal era now to maintain the economic stability of the Nawawi Farm livestock group.

Feeding independence is one of the target achievements desired by every farmer. One of them is the Bago Mulyo livestock group. The Bago Mulyo livestock group is a livestock group located in Gumukmas District, Jember Regency. Several problems of the Bago Mulyo Livestock Group which reduce production by 5% because the prices of production facilities (seeds, fertilizers, pesticides, and feed) are expensive and the distribution is not smooth; the need for food will increase by 5% due to panic buying and food supplies. The distribution of feed was not optimal, making farmers have to find solutions so that feed ingredients are still available. One solution is to utilize existing feed ingredients and maintain their feed quality until they are available throughout the year, namely by silage method. The implementation of the service consists of several activities, the first was coordination with the head of the Bago Mulyo livestock group, purchased silage materials, simulated modified silo tools, implementation of community service, and surveying the results of community service activities. The results of the community service survey which have shown that 100% of farmers who participate in the service activities understand silage technology with the addition of silo modification from previously only 43% who understand silage technology. The conclusion is an increase in understanding of silage technology which is one of the indicators of support for the service team in carrying out service activities for the Bago Mulyo Livestock Group, so that this technology can be applied properly for the sustainability of the cattle business in the Livestock Group.

This study aimed to determine the effect of 15 days refrigeration storage on lactose content, reducing sugars, and the pH value of yoghurt by addition of rice bran. The experimental design used a completely randomized design (CRD) for 4 treatments and 5 replications. The treatments consisted of T0 (without storage), T1 (5 storage days), T2 (10 storage days), and T3 (15 storage days). The results showed that lactose content, reducing sugar, and pH value of yoghurt were analyzed by analysis of variance (ANOVA). If there were significant differences, then further tested by Duncan's Multiple Range Test. Yoghurt by addition of rice bran stored for 15 days in the refrigerator could reduce lactose content and pH values and increased the level of reducing sugar, so that be able to maintain the quality and freshness of yoghurt.

Mineral absorption in ruminants have not been maximal. This would be seen from the various problems that occur in ruminants, one of which was caused by mineral deficiency, especially the mineral Selenium (Se). Therefore, it was necessary to have applied technology to increase the absorption of Se minerals, one of which was used by bionanomineral technology. The purpose of this study was to determine the production of bionanomineral Se from various types of Lactic Acid Bacteria (LAB) strains. The method used consisted of preparing tools and materials, breeding lactic acid bacteria, making Bionanomineral Se, and observed the production of Bionanomineral Se. The research treatment consisted of 2 stages, namely the first stage consisting of 4 treatments of different LAB strains: TSD 10, SPCE, DR162, and IA2, stage 2 each LAB strains were given treatment doses of 25 ppm and 50 ppm. The parameters observed included Stage 1: Bionanomineral production produced by intracellular and extracellular bacteria, stage 2: Optical Density (OD) and pH. The research design used a quantitative descriptive. The results showed that extracellular bionanomineral production was more than intracellular, the addition of 25 to 50 ppm Se showed that the OD of the four bacterial strains survived, and the pH results varied from each bacterial strain but were still within the normal range. The conclusion of this research was the production of bionanomineral Se as much as 25 ppm and 50 ppm in various types of different LAB strains, would be used as a potential source of organic Se minerals for ruminants.

Objective: The objective of this study was to examine the accuracy of estimating the nutrient content in rice bran as a feed ingredient by using Near Infrared (NIR) technology compared to proximate analysis method.Methods: Rice bran was used as feed sample to compare the results of data analysis using these two methods. In this study the Fourier Transform Near-infrared used infrared with wavelength of 12500-4000 cm-1. The OPUS 7.8 software was integrated with NIRS. The model was made by using Partial Least Square regression analysis to correlate the result of the spectrum and the result of proximate analysis method.Results: In this study, the nutrient content in rice bran available in markets, which commonly are Crude Protein (CP), ether extract (EE), and Crude Fiber (CF), are quite varied and wide in range, so that The curve prediction/true showed up wider and did not cover the entire surface of the line. In consequence two outliers were removed so that the accuracy value could be increased in measuring the quality of animal feed as indicated by the improvement of the coefficient of determination or R2, Root Mean Square Error for Cross Validation (RMSECV), and Standard Error (SE).Conclusions. NIR is a useful tool to estimate nutrient composition of rice bran available in the market especially for CP, EE, and CF by removing two outliers. The Prediction / True curve does not widen after removing two outliers, and can improve R2, RMSECV, and SE values.

Maximal oxygen uptake is a measure of cardiorespiratory capacity that shows human body fitness. Resting heart rate shows the ability of the heart to pump blood throughout the body thus resting heart rate related to the maximum oxygen volume. The young adult is an important phase of human in determining the productivity of the level of life. Maximum oxygen volume can be related to resting heart rate, but this has not been studied in detail regarding the relationship between maximal oxygen volume and resting heart rate in young adults. The purpose of this study was to determine the relationship between maximal oxygen volume and resting heart rate of young adults. This research uses cross sectional method. The number of research samples was 38 students from the Faculty of Medical Education, Sebelas Maret University (UNS). The dependent variable tested in this study was resting pulse rate and the independent variable was maximal oxygen volume. The research was conducted at the Physiology Laboratory of Sebelas Maret University, Surakarta. Resting heart rate was calculated by sleeping position in the supine position for 15 minutes then measured by pulse oximetry and maximal oxygen volume was calculated by Astrand-Rhyming Step Test. The results showed that the data were normally distributed so that the Pearson correlation test could be performed. The results of the correlation test showed that the value of p = 0.000 (p < 0.05) which indicated there was a significant correlation between the two variables tested and the Pearson correlation value of - 0.612 which indicated a negative correlation with a strong correlation strength. This study concludes that there is a significant correlation between maximal oxygen volume and heart rate of young adults with a negative correlation.
