“…Cabang olahraga panahan merupakan olahraga outdoor maka angin sangat berpengaruh saat melepaskan anak panah, karena permasalahan ini sangat berpengaruh terhadap performa atlet saat bertanding (Eckelt et al, 2020). Oleh karena itu, dilakukan penelitian agar diketahui adanya hubungan konsentrasi terhadap kemampuan memanah.…”

Konsentrasi ini sangat penting dibutuhkan untuk atlet panahan yang bertujuan untuk mengetahui hubungan tingkat konsentrasi terhadap kemampuan panahan di jarak 50 meter. Jenis penelitian ini korelasi untuk mengetahui sebuah hubungan. Sampel ditentukan dengan teknik Purposive Sampling jumlah sampel 12 atlet panahan di Kabupaten Banyumas yang masih berstatus Sekolah Menengah Atas (SMA). Instrumen yang digunakan angket konsentrasi dengan 20 butir pertanyaan dan tes memanah jarak 50 meter. Teknik analisis data dalam penelitian ini diolah dengan menggunakan program SPSS dengan uji statistik. Berdasarkan hasil uji normalitas menggunakan teknik Kolmogorov Smirnov didapatkan hasil sig. 0,167 (konsentrasi) dan sig. 0,200 (memanah jarak 50 m) p>0,05 data berdistribusi normal. Hasil uji homogenitas menggunakan teknik Levene's Test of Equality didapatkan nilai sig. 0,133 (p>0,05) disimpulkan bersifat homogen. Berdasarkan hasil tes konsentrasi menggunakan kuesioner ini terdapat 4 atlet (33,3%) yang tingkat konsentrasi dirinya dalam kategori sangat tinggi, 2 atlet (16,7%) kategori tinggi, 3 atlet (25%) kategori sedang, dan 3 atlet (25%) kategori rendah. Kemudian dilanjutkan dengan teknik analisis regresi linier sederhana. Hasil penelitian menunjukkan terdapat hubungan yang signifikan antara konsentrasi yang tinggi terhadap kemampuan memanah atlet pada jarak 50 meter dengan hasil sig. 0,000 (p<0,05), yang berarti memanah membutuhkan konsentrasi yang tinggi. Kata kunci: Konsentrasi, Akurasi memanah, Atlet panahan. This concentration is very important for archery athletes who aim determine the relationship between concentration levels and archery ability distance of 50 meters. This type of research is correlation to determine relationship. The sample determined by purposive sampling technique, the number of samples was 12 archery athletes in BanyumasRegency who were still in high school (SMA) status. The instrument used was a concentration questionnaire with 20 questions and archery test distance of 50 meters. The data analysis technique this study was processed using SPSS program with statistical tests. Based results the normality test using the Kolmogorov Smirnov technique, results obtained were 0.167 sig. (concentration) and 0.200 sig. (archery distance 50 m) p>0.05 data were normally distributed. The results homogeneity test using Levene's Test of Equality technique obtained sig. value of 0.133 (p> 0.05) and concluded homogeneous. Based results concentration test using this questionaire, 4 athletes (33.3%) whose self-concentration levels were very high category, 2 athletes (16.7%) high category, 3 athletes (25%) moderate category, and 3 athletes (25%) low category. Then proceed with simple linear regression analysis techniques. The results showed that there was significant relationship between high concentration on the archery ability of athletes at a distance of 50 meters with a sig. of 0.000 (p <0.05), which means that archery requires high concentration.

“…In almost all areas of science and technology sensors are becoming more and more prevalent. In recent years we have seen applications of sensor technology in fields as diverse as energy saving in smart home environments [1], performance assessment in archery [2], activity monitoring of elderly [3], recognition of human stress [4], detection of mooring ships [5], early detection of Alzheimer disease [6], dietary monitoring [7] and recognition of emotional states [8], to name just a few.…”

The past decade has seen an increased interest in human activity recognition. Most commonly, the raw data coming from sensors attached to body parts are unannotated, which creates a need for fast labelling method. Part of the procedure is choosing or designing an appropriate performance measure. We propose a new performance measure, the Locally Time-Shifted Measure, which addresses the issue of timing uncertainty of state transitions in the classification result. Our main contribution is a novel post-processing method for binary activity recognition. It improves the accuracy of the classification methods, by correcting for unrealistically short activities in the estimate.

The past decade has seen an increased interest in human activity recognition based on sensor data. Most often, the sensor data come unannotated, creating the need for fast labelling methods. For assessing the quality of the labelling, an appropriate performance measure has to be chosen. Our main contribution is a novel post-processing method for activity recognition. It improves the accuracy of the classification methods by correcting for unrealistic short activities in the estimate. We also propose a new performance measure, the Locally Time-Shifted Measure (LTS measure), which addresses uncertainty in the times of state changes. The effectiveness of the post-processing method is evaluated, using the novel LTS measure, on the basis of a simulated dataset and a real application on sensor data from football. The simulation study is also used to discuss the choice of the parameters of the post-processing method and the LTS measure.
