ABSTRACT

objective

To identify the effects of carbohydrate, fluid and electrolyte of supplementary feeding on the performance of athletes. Jatiluhur National Training Center for Dragon boat, Purwakata.

Methods Dragon boat is one of the branches of sport, which has brought fame to Indonesia internationally. Athletes' physical performance very much enhances their sport performance. Taking part in races repeatedly, particularly in a short span of time will decrease their performance. However. Supplementary food can tackle this problem. Dragon boat is a sport which requires the combination of endurance and power. Therefore it demands carbohydrate as the main source of energy. The purpose of this research is to identify the effects of supplementary foods, either food or drink, such as carbohydrate, fluid and electrolyte on the physical changes of the athletes. It is a pre- and post-experimental test, using the control group as the same subjects as the treatment group. The physical performance test was conducted in land (dragon ergometer and running test of Balke Method), and on water (touring test). During those tests. administration of apples and 1 or bananas as supplementary food and sports drink containing carbohydrate, fluid and electrolyte were given

The energy intake ranged from 404,18 to 415,19 Kcal. The intake for carbohydrate was between 97.13 to 103,65 g.

Results : Carbohydrate intake before treatment was 59,7 % and after treatment was 61,4 %. Blood ureum level after treatment (27,96 mg/dL) was lower than before treatment (36,91 mg/dL). Blood creatine kinase level after treatment (55,55 mg/dL) was lower than before treatment (64,23 mg/dL). Hematocrite after treatment (45,32 vol %) was lower than before treatment (46,50 vol %). Sodium level after treatment (142,23 mg/L) was lower than before treatment (145,50 mg/L.). Potassium level after treatment (4,35 mg/L) was higher than before treatment (3,93 mg/dL). Changes of weight also accrued after treatment (0,02 kg), a little lower than before treatment (0,50 kg). By means of statistical test was found that the statistical significance was p = 0,013. The results of the physical performance test in land and on water have shown that supplementary feeding enhances the speed at the beginning and end of treatment than before the treatment. Also, the time distance needed at the beginning and the end of the races was shorter than before treatment.

Conclusions : Supplementary feeding in the form of carbohydrate, fluid and electrolyte has great influences on the storage of muscle carbohydrates, dehydration prevention, in the races which are carried out repeatedly in a short span of time. It can meet the nutrient requirement adequacy of main dish as well."

"Penelitian ini merupakan langkah awal yang terbilang baru di Formasi Jatiluhur, Sungai Cibeet untuk menganalisis proses diagenesis, mengidentifikasi fitur diagenesis dan sejarahnya. Daerah penelitian tersusun oleh batuan silisiklastik berupa batupasir, batulanau, batulempung, terdapat pula batuan bersifat karbonatan. Sebanyak sepuluh sampel dilakukan analisis petrografi untuk menentukan karakterisasi tekstur dan mineralogi batuan. Selain analisis petrografi, analisis SEM dan XRD sebanyak masing-masing tiga sampel dapat digunakan untuk studi diagenesis. Beberapa proses diagenesis seperti kompaksi, sementasi, disolusi, dan penggantian mineral dapat memengaruhi keterbentukan batuan Formasi Jatiluhur. Proses kompaksi menghasilkan kontak antarbutir berupa point, long, concavo-convex, dan sutured serta semen yang ditemukan berupa semen kalsit dan mineral lempung seperti albit, ilit, kaolinit, dan smektit. Mineral kuarsa, mika, dan feldspar mengalami penggantian. Proses-proses diagenesis tersebut mengakibatkan perubahan porositas dari batuan. Tipe-tipe porositas didominasi oleh tipe intergranular dan intrapartikel dengan persentase antara 5-30%. Sejarah diagenesis pada daerah penelitian diawali oleh tahap eogenesis, mesogenesis, dan telogenesis. Dengan adanya pelaksanakan studi diagenesis, maka kualitas reservoar (misalnya) dapat ditentukan. Penelitian ini menunjukan bahwa proses diagenesis mengakibatkan adanya heterogenitas batuan Formasi Jatiluhur di sekitar aliran Sungai Cibeet.

This research is a relatively new to conduct in the Jatiluhur Formation, especially Cibeet River that aimed to analyse the diagenesis process and identify diagenesis features and its history. The research area is composed of siliciclastic rocks in the form of sandstone, siltstone, and claystone but there are also carbonate rocks. A total of ten samples were subjected to petrographic analysis to determine the characterisation of rock textures and mineralogy. In addition to petrographic analysis, SEM and XRD analysis of three samples each are used for diagenesis studies. Several diagenesis processes such as compaction, cementation, dissolution, and mineral replacement affected the rock formation of the Jatiluhur Formation. The compaction process produced contact between grains in the form of point, long, concavo-convex, and sutured contacts as well as cement found in the form of calcite cement and clay minerals such as albite, illite, kaolinite, and smectite. Quartz, mica, and feldspar minerals underwent mineral replacement. These diagenesis processes resulted in changes in the rock porosity. The types of porosity are dominated by intergranular and intraparticle types with the percentage between 5-30%. The history of diagenesis in the research area began with the stages of eogenesis, mesogenesis, and telogenesis. With the implementation of a diagenesis study, the quality of the reservoir (for example) can be defined. This study shows that the diagenesis process resulted in the heterogeneity of the Jatiluhur Formation rocks around the Cibeet River streams."

Stunting is one of the public health problems in Indonesia which results long termnegative impact. West Java is the province with the highest number of stunted children.A proximate determinant associated to stunting is maternal nutrition and this associationmight be influenced by socioeconomic factors. The aim of this study was to assess theeffect of maternal nutrition and socioeconomic factors on child stunting according to thegroup age. This study used data from Survey of Nutrition Status Monitoring PSG 2017which included data of children under five, pregnant women or women of childbearingage, and households. Effect of mother 39 s nutritional status height and BMI on Heightfor Age Z score HAZ was analysed using multivariable linear regression. The highestprevalence of stunting was in children aged 24 59 months. The higher the education ofmother and father, the lower the prevalence of child stunting. The prevalence of stuntingwas higher in rural areas and mothers with height less than 150 cm. In multivariableanalysis, the HAZ of 0 11 months infants was affected by mother rsquo s height, mother rsquo s BMI,mother rsquo s education, and residence classification. Whereas in infants aged 24 59 monthsHAZ was affected by mother rsquo s height, mother rsquo s BMI, mother rsquo s education, mother rsquo s workstatus, and residence classification. The biggest effect of mother rsquo s height on HAZ was inthe infants aged 6 11 months and the effect was decreased when children aged 12 23months. While the effect of mother 39 s BMI on HAZ did not differ between age group ofchildren. The prevalence of stunting in West Java are relatively high, so appropriateinterventions are needed to increase the child 39 s linear growth. This can be tackled throughenhancing the knowledge of mother and child nutrition for young women, women, andpregnant women, also give adequate nutrition for infants, especially during the first 1000days of life.Keywords Stunting, maternal nutrition, socioeconomic factor."
