Saat ini sedang berkembang pencatatan waktu otomatis yang dijual oleh beberapa perusahan perlatan olahraga ternama seperti. Namun sayangnya, harga perangkat tersebut sangatlah mahal, dan membuat setiap pelatih ataupun praktisi olahraga terkendala untuk mendapatkannya. Karena fakta dan permasalahan tersebut, maka penelitian ini bertujuan untuk mengembangkan prototipe sistem pencatatan waktu untuk pengukuran kecepatan secara otomatis pada sprint 60-meter, dengan menggunakan perangkat sederhana dengan harga yang murah, namun memiliki tingkat presisi dan akurasi yang baik. Penelitian ini menggunakan metode penelitian research and development, dimana dalam proses pengembangan dan pembuatan pencatatan waktu otomatis, penelitian ini mengambil contoh dari timing gate yang sudah divalidasi sebelumnya. Dalam penelitian ini, kami juga sudah melakukan uji coba kepada 12 atlet sprinter (tinggi badan 172.8 ± 9.31, berat badan 61.05 ± 6.90, BMI 20.38 ± 0.87) terkait kegunaan alat tersebut. Rata-rata kecepatan lari seluruh subjek pada pos 10-meter adalah 2.44 ± 0.23 detik, pos 20-meter adalah 3.71 ± 0.18 detik, pos 30-meter adalah 4.75 ± 0.22 detik, pos 40-meter adalah 6.39 ± 0.31 detik, 50-meter adalah 7.65 ± 0.41 detik, dan 60-meter adalah 9.12 ± 0.49 detik. Penelitian research and development terkait pengembangan pencatatan waktu otomatis dalam penelitian ini, menunjukkan bahwa pencatatan waktu otomatis dapat dibuat dengan harga ekonomis, dan dapat digunakan untuk mengukur kecepatan lari 60-meter. Development of track timer prototype system for automatic speed measurement on 60-meter sprints AbstractCurrently, automatic track timers are being sold by several well-known sports equipment companies. Unfortunately, the price of the device is very expensive and makes every coach or practitioner constrained to get it. Because of these facts and problems, this research was aimed to develop a prototype track timer system for automatic speed measurement on a 60-meter sprint, using a simple device at a low price, but has a good level of precision and accuracy. This study used to research and development research methods, wherein the process of developing and manufacturing automatic track timers, this study takes the example of a timing gate that has been validated before. In this study, we have also tested 12 sprinters (height 172.8 ± 9.31, weight 61.05 ± 6.90, BMI 20.38 ± 0.87) related to the use of the tools. The average running speed of all subjects on a 10-meter post is 2.44 ± 0.23 seconds, a 20-meter post is 3.71 ± 0.18 seconds, a 30-meter post is 4.75 ± 0.22 seconds, a 40-meter post is 6.39 ± 0.31 seconds, 50- The meter is 7.65 ± 0.41 seconds, and the 60-meter is 9.12 ± 0.49 seconds. This research shows that track timers can be made at economical prices, and can be used to measure 60-meter running speed.

The importance of this research is to provide a new development in the form of the development of the addition of L-shaped pipe accessories added to the pipe in each tank from previous studies, Implementation of previous research has not been maximized when used in the kitchen of Makassar Tourism Polytechnic so that modifications are made, because it is not there is a difference in waste from each tank, furthermore this research uses research and development research methods with the development of existing models by not build the new construction from scratch, while the development of this research is to add pipes in the form (L) or L-shaped pipe attached to the tank number one (1) as the first tank for waste that is disposed of often containing foam soap, fat and heavy sediments, then in the second tank (2) which already does not contain foam, grease, and heavy sediments, reattach the L pipe to reduce the content is what if it still exists, then add sand material, and gravel, as the dissolved material Chemical Oxygen Demands (COD) dissolved in the third tank (3) before being channeled into the public sewer. This research recommends that before disposal of liquid waste from processed food, it is better to do the separation of the sediment contained in the liquid waste and then to develop it further to get more perfect results, especially the criteria for Wastewater Clarity.
