Abstract

Swiftlet nest farming is a source of economic income for several regions in Indonesia, including Central Kalimantan. The constraint faced by swiftlet nest farmers is the use of a manual counting system by estimating the number of birds, which has a high error rate. This problem necessitates the design of a swiftlet counting system. This research aims to design and build an appropriate technology-based monitoring system. The technology required is one that can be used to monitor the number of swiftlets entering and leaving the swiftlet house in real time. The method used is the characterization and calibration of infrared sensors, then designing a sensor data design and acquisition system. The NodeMCU ESP8266 measures the number of objects using an infrared sensor displayed through a Liquid Crystal Display (LCD) and Blynk. Data collection was carried out in six trials with variations in the number of objects passed through the sensor. The test results show an average error percentage of 3% and an accuracy value of 97.5% when throwing one object and an error value of 6% and an accuracy value of 94% when throwing one object. The measurement data is displayed on the LCD and sent to the Blynk application via a smartphone for remote monitoring.

Abstract

Table tennis requires a comprehensive mastery of basic techniques, with the backhand stroke often considered more complex than the forehand. A preliminary study of 55 college students showed that backhand proficiency (58.2%) was lower than that of the forehand (78.2%), with difficulties in accuracy, coordination, body position, and consistency. This systematic literature review (SLR) aims to identify, analyze, and evaluate effective training models for improving table tennis backhand skills among college students. Following the PRISMA 2020 guidelines, a literature search was conducted in the Google Scholar, PubMed, ScienceDirect, and Scopus databases for articles published between January 2020 and March 2026, yielding 18 articles from 847 identified records. The review identified six effective training models: (1) multi-ball drills, (2) partner drills, (3) goal-based training, (4) external attention-based training, (5) digital technology-based training, and (6) sports education models. The principle of analogy from other sports, such as volleyball and futsal, also supports the implementation of structured training and target-based patterns. A combined training model that integrates technical variations, immediate feedback, and structured repetition has been shown to provide optimal results for students. These findings provide evidence-based guidance for designing backhand training programs in higher education settings.

Abstract

Problems in coaching novice sepak takraw athletes at the university level often lie in the lack of structured and measurable basic technique training patterns, which results in weak fundamental mastery. This study aims to analyze the effectiveness of applying systematic basic technique training patterns for sepak sila and sepak kura in improving the skills of novice athletes. The method used was a quasi-experiment with a one-group pretest-posttest design on 20 beginner athletes from the University of Palangka Raya. The research instrument was a validated skills test (Aiken's V validity > 0.80, reliability r > 0.85) to measure ball control, passing accuracy, defense, and attack. The structured training intervention was given for 6 weeks with a frequency of 3 times per week. The results of the paired sample t-test showed a significant increase in all skill aspects (p < 0.05), with an average score increase of between 16.2 and 17.2 points. The discussion relates these findings to motor learning theory, in which repetitive and gradual training strengthens motor memory and neuromuscular coordination. It is concluded that structured basic soccer and soccer training patterns are effective as a foundation for training beginner athletes.

Abstract

ABSTRAK. Salah satu komponen utama kondisi fisik dalam olahraga sepak bola adalah daya tahan VO2max. Analisis kondisi fisik tidak hanya dilakukan untuk setiap pemain, tetapi juga perlu memiliki data per posisi bermain. Metode penelitian ini adalah analisis deskriptif kuantitatif dengan ukuran sampel 30 pemain yang terdiri dari 6 posisi bermain. Hasil penelitian individu menunjukkan bahwa 13% (4 pemain) berada dalam kategori yang baik, 60% (18 pemain) dalam kategori sedang, 17% (5 pemain) dalam kategori kurang, 10% (3 pemain) dalam kategori yang kurang sekali, dan 0% (0 pemain) dalam kategori yang sangat baik, sedangkan hasil analisis berdasarkan posisi bermain didapatkan tingkat rata-rata VO2max posisi penjaga gawang (GK) sebesar 35,93 dalam kategori kurang, pemain belakang (CB) sebesar 45,26 (sedang), posisi bek sayap (FB) sebesar 43,68 (sedang), posisi gelandang (CM) sebesar 51,88 (baik), posisi sayap (WF) sebesar 45,70 (sedang) dan posisi striker (CF) dari 44,80 (sedang) dalam satuan ml/kg/menit. Data ini menunjukkan perlunya penyusunan program latihan untuk memperbaiki kondisi fisik sesuai dengan karakteristik posisi bermain. Kata Kunci : Analisis, VO2max, Sepakbola ABSTRACT. One of the main components of physical condition in the sport of football is endurance VO2max. Physical condition analysis is not only carried out for each player, but also needs to have data per playing position. This research method is quantitative descriptive analysis with a sample size of 30 players consisting of 6 playing positions. Individual research results show that 13% (4 players) are in the good category, 60% (18 players) in the medium category, 17% (5 players) in the poor category, 10% (3 players) in the very poor category, and 0% (0 players) in the very good category, while the results of the analysis based on playing position found an average level VO2max Goalkeeper (GK) was 35.93 in the very poor category, defender (CB) was 45.26 (medium), wing defender (FB) was 43.68 (medium), midfielder (CM) was 51.88 (good ), Winger (WF) of 45.70 (medium) and Striker (CF) of 44.80 (medium) in units of ml/kg/min. These data indicate the need to develop a training program to improve physical condition in accordance with the characteristics of the playing position. Keywords: Analysis, VO2max, Football
