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 Konsumsi Pangan dan Status Gizi dengan Tingkat Kebugaran Atlet Taekwondo Remaja di Pemusatan Latihan Nasional Cipayung, Bogor
Abstrak: The general objective of study was to analyze food consumption, adequacy ratio, nutritional status, and fitness level of adolescents taekwondo athletes in Centralization of National Training Cipayung, Bogor. The research used cross sectional study design with 23 adolescents athletes as samples. The primary data included characteristic of samples, nutritional status by anthropometry (body mass index), and food consumption. The secondary data included fitness level by bleep test (VO2 max values), sit and reach test (flexibility), sit up and squat jump (muscle endurance), and overview of the study site which was Centralization of National Training. The study showed that overall athletes has normal nutritional status. Most athletes were lack of sufficient levels of energy and protein. There was positive correlations between the ages of athletes with flexibility (p<0,05, r=0,456) and muscle endurance (sit up test) (p<0,05, r=0,456). The correlations between with fitness level (VO2 max) was positive significantly correlated (p<0,05, r=0,456).

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
