Judul: Relationship between Nutritional Status,  Diet Quality, and Isotonic Drink Frequency with Anaerobic Endurance in  Taekwondo Speed Club Wonosobo
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan antara status gizi, kualitas diet, dan frekuensi minuman isotonik dengan daya tahan anaerobik pada atlet taekwondo Speed Club Wonosobo. Desain penelitian ini adalah cross sectional study dan dipilih secara purposive sampling. Data status gizi ditentukan menggunakan indikator z-score IMT/U. Sebagian besar status gizi subjek tergolong gizi baik (-0,63 SD). Data kualitas diet didapatkan dari food recall 2x24 jam dan diukur menggunakan Diet Quality Index Adolescent (DQI-A). Kualitas diet subjek (70,5%) dikategorikan dalam kuartil 4 (>61,2%). Frekuensi minum minuman isotonik didapatkan melalui wawancara dengan kuesioner dan rata-rata subjek minum minuman isotonik dalam frekuensi kadang (2-3 kali seminggu). Daya tahan anaerobik diukur dengan Running-based Anaerobic Sprint Test (RAST). Indeks kelelahan subjek tergolong tidak lelah (5,29 watt/detik). Terdapat hubungan yang searah, cukup kuat, dan signifikan antara status gizi dengan indeks kelelahan (p<0,05), serta terdapat hubungan yang tidak searah, cukup kuat, dan signifikan antara kualitas diet dengan indeks kelelahan (p<0,05), namun hubungan antara frekuensi minuman isotonik dengan indeks kelelahan tidak signifikan dan sangat lemah (p>0,05)., This study aims to analyze the relationship between nutritional status, diet quality, and frequency of isotonic drinks with anaerobic endurance in taekwondo Speed Club Wonosobo athletes. This research design is a cross sectional study and selected by purposive sampling. Nutritional status data was determined using the IMT/U z-score indicator. Most of the subjects's nutritional status was classified as good nutrition (-0.63 SD). Diet quality data was obtained from 2x24 hour food recall and measured using the Diet Quality Index Adolescent (DQI-A). The diet quality of the subjects (70.5%) was categorized in quartile 4 (>61.2%). The frequency of drinking isotonic drinks was obtained through interviews with questionnaires and the average subject drank isotonic drinks in the frequency of sometimes (2-3 times a week). Anaerobic endurance was measured by Running-based Anaerobic Sprint Test (RAST). The fatigue index of the subjects was classified as not fatigued (5.29 watts/second). There was a unidirectional, moderately strong, and significant relationship between nutritional status and fatigue index (p<0.05), and there was an unidirectional, moderately strong, and significant relationship between diet quality and fatigue index (p<0.05), but the relationship between isotonic drink frequency and fatigue index was not significant and very weak (p>0.05)

Judul: Hubungan Antara Karakteristik Atlet, Tingkat Kecukupan Gizi, dan Status Gizi Dengan Tingkat Kebugaran Atlet Taekwondo di SMA Ragunan Jakarta
Abstrak: Nutrition is a factor to consider for the achievements of athletes to guidance in the training game until the game. For athletes, nutrient intakes associated with the sport had significance in addition to maintain fitness as well to increase the achievements in sport athlete who participated. In this study had been studied about anthropometry, sufficient levels of nutritional status, fitness level of athletes from the Senior High School Ragunan in South Jakarta. The objective of this study was to analyze the characteristics of the athletes, the consumption, level of nutritional adequacy, nutrition status, and fitness level of taekwondo's athletes. Design of the experiments was cross sectional study. The data used were primary and secondary data in the form of characteristic examples, data knowledge of nutrition, anthropometry (weight and height), food consumption, level of fitness results of balke test (VO2 max values), and an overview of the school which is study site. Analyses were performed by data entry, and then processed by a computer program Microsoft Excel 2007 and Statistical Program Social Sciences (SPSS) version 19.0, then the correlation between variables was tested using Pearson and Spearman Correlation test. The results of this study showed most of the taekwondo athletes had normal nutritional status. However, consumption of athletes still do not fulfill the nutrition needs of the athletes, most of the athletes have a lack of sufficient levels of energy. The average value of VO2 max that male athlete were 45.49 ± 4.74 ml/kg/min, while the average value of VO2 max female were below compare to male sex, amounting to 42.03 ± 3.13 ml/kg/min. The relationship between weight loss fitness level had a significant negative correlation (p = 0.028, r = -0.448) and the result of the independent T test between VO2max male and female were highly significant (p<0.05)

Judul: Revisi marga Ptychopyxis miquel (Euphorbiaceae) di kawasan Malesia
Abstrak: Ptychopyxis adalah salah satu marga dari 317 marga yang termasuk ke dalam suku Euphorbiaceae. pertama kali dipublikasikan oleh Miquel (1860). Marga ini Marga ini pernah dimasukkan kedalam marga lain, yaitu Podadenia, Mallotus dan Clarorivinia. Fakta tersebut menunjukkan bahwa batasan marga Ptychopyxis belum cukup mantap. Persebaran marga ini menurut Van Welzen (1993) jumpai di Thailand, Indochina dan kawasan Malesia, di seluruhnya ada 23 jenis dan 10 jenis diantaranya terdapat di kawasan Malesia. Marga ini umum berperawakan pohon dan berumah dua, tumbuh di hutan hujan dataran rendah sampai pada ketinggian 1500 m dpl. Penelitian taksonomi yang komprehensif tentang marga ini telah dilakukan oleh Airy Shaw pada tahun 1960; sejak saat itu belum ada penelitian taksonomi yang lebih kompre- hensif, khususnya untuk kawasan Malesia. Kini dengan bertambahnya jumlah spesimen koleksi baru, maka tepatlah kiranya dilakukan revisi marga. Tujuan penelitian ini adalah untuk memberikan batasan marga serta jenis-jenisnya yang termasuk dalam Ptychopyxis selain itu diteliti pula hubungan kekerabatan antar jenis dan keterangan-keterangan..dst
