Formula Kite is an Olympic sport that mainly differs from other kitesurfing modalities for the use of a hydrofoil. It is considered an extreme sport due to the great technical ability required. Regarding performance, the variables that determine performance in a real competition situation have not been studied, and even less so with Olympic sailors. Therefore, the objective of this study was to determine the technical and tactical variables that differentiate elite sailors. The sample consisted of 42 Olympic sailors of the Formula Kite class, who were evaluated in three World Cups. Using a GPS device, the speed, distance traveled, maneuvers, and time spent on the courses of upwind, downwind, and beam reach were recorded. The highest-level sailors presented a higher speed in upwind/downwind/beam reach and a shorter time in upwind and beam reach. Performance seems to be more strongly influenced by technical variables, such as speed, than by tactical variables.

The study considered performance analysis and feedback from the perspective of the performance analyst through the investigation of the ‘what’, ‘how’ and ‘when’ of practice within a selection of Olympic sports. Twenty-three performance analysts (experience 6.4 ± 4.1 years) engaged in a structured interview (85 ± 15 min) regarding their processes within applied practice. Likert scales (All the time, Often, Sometimes, Rarely and Never) were used to facilitate cross-sport and environment comparison. The performance analysts highlighted the experience of their coaches as the most prominent feature influencing analysis direction, and time had the greatest impact upon feedback provision. The main analysis techniques used were video, profiling and performance reports. Feedback was delivered primarily either, (1) < 1-h post-performance within sessions lasting < 10-min or (2) the following day within sessions lasting 25 + min. Video feedback was usually coach led; however, data delivery was more evenly distributed between coach and analyst. Very similar processes across the participants were identified, despite a wide variety of sports and participant experience levels. The findings have begun to illustrate practice within elite sport whilst highlighting the importance and need for further practitioner-based investigation regarding the use of performance analysis and feedback within applied contexts.

Produktivitas tanaman kelapa sawit sangat dipengaruhi oleh kualitas benih yang digunakan. Pemakaian benih kelapa sawit bersertifikat dipercayai oleh petani yang kritis dalam memberikan produktivitas tanaman kelapa sawit yang bermutu dan kontinyu. Sikap dan kepuasan petani dalam menggunakan benih kelapa sawit bersertifikat merupakan hal yang perlu dicermati untuk memahami keinginan petani. Penelitian ini dirancang untuk mengamati hal tersebut. Sikap petani dianalisis dengan menggunakan pendekatan multiatribut fishbean sedangkan kepuasan dianalisis dengan menggunakan Important Performance Analysis (IPA) dan Customer Satisfied Index (CSI). Berdasarkan penelitian diketahui bahwa atribut-atribut yang menentukan sikap dan kepuasan petani adalah hasil panen, ketahan terhadap hama dan penyakit, umur tanaman, daya tumbuhbenih, efisiensi penggunaan pupuk, jenis varietas, ukuran benih, sertifikasi benih, harga benih, harga Tandan Buah Segar (TBS), kemudahan dalam akses benih, stok benih, kemudahan dalam menjual TBS, dan promosi toko.Analisis multiatribut Fishbeinmenunjukkan sikap netral terhadap benih kelapa sawit bersertifikat (76 persen). Sementara hasil CSI menunjukkan bahwa 70.04 persen petani merasa puas atas atribut-atribut pada benih kelapa sawit bersertifikat.
