This research is motivated by the importance of physical components to the results of the speed of the smash on table tennis including reaction time and arm power. The purpose of this study was to determine the relationship between reaction time and arm power with the speed of a smash ball in a table tennis game. This study uses a correlational research method. The sample in this study were active members of the Jabung Garut club. A total of 20 samples were taken using purposive sampling technique. The instruments used in this study are the ruler drop test to measure the speed of reaction time and the softball throw test to measure arm power. Data analysis used Statistical Product for Social Science (SPSS) version 22. The results of data analysis showed that there was a significant relationship between reaction time and the smash ball speed, which was p = 0.000 <0.05 with a value of r = -0.719, while the relationship between arm power and ball speed smash results p = 0.001 <0.05 which means there is a significant relationship, and the relationship between reaction time and arm power together with the ball speed smash results produce a significant relationship with the significance of 0.001 <0.05 and r = 0.547. From these results it can be concluded that there is a significant relationship between reaction time and arm power with the speed of the ball smash in table tennis.

This study aims to determine the growth and yield of Pakcoy plants with nutrient concentasry and liquid organic fertilizer in the Wicksist hydroponics system. The study was carried out on February 14, 2022 – April 14, 2022 at Green House Umsida using a randomized design method of groups with a single factor, namely a combination of ab mix nutrient concentration and liquid organic fertilizer consisting of 4 levels: AB Mix Nutrient Concentration 2000 ppm + Without POC, AB Nutrition Mix Concentration 1500 ppm + POC 500 ppm, Ab Mix Nutrient Concentration 1000 ppm + POC 1000 ppm,    Ab Mix Nutrient Concentration 500 ppm + POC 1500 ppm. Observation of plant height, weevil diameter, leaf julah, wet weight and dry weight. The results of this study showed that the combination of AB MIX nutrients with liquid organic fertilizer from leri water fermented by lactobacilus bacteria affected the growth and production of mustard crops. On the K3 treatment (Ab Mix Nutrient Concentration 1000 ppm + POC 1000 ppm) had a significant influence on all observations. Providing a balanced concentration of nutrients with liquid organic fertilizers reduces the use of chemical fertilizers

This research attempts to examine the effects of homesickness on Harry potter in J. K. Rowling’s Harry Potter and the Prisoner of Azkaban. Homesickness as a mental illness is prevalent in people; therefore, the investigation used Harry Potter as its subject. The research adopts the theory of homesickness proposed by Fisher (1989). The research shows the harshness of being homesick in a society that we have little control of and in situations where we have no choice on how to proceed. It highlights the need of attachments in a social sense for individuals who are suffering from homesickness because it is one of the definite cure for a serious and dangerous mental illness. It can affect anyone regardless of age, living conditions, and state of mind.

Penelitian bertujuan untuk menganalisis efisiensi saluran pemasaran dan risiko distribusi Melon yang dijual di pasar tradisional Kota Bogor. Penelitian dilaksanakan di Pasar Jambu Dua dan Pasar Baru Bogor, pemilihan lokasi ini dilakukan secara purposive karena kedua pasar tersebut merupakan pasar tradisional terbesar di Kota Bogor yang mendistribusikan buah dengan kuantitas terbanyak salah satunya yaitu Melon. Penentuan sampel dilakukan secara purposive untuk pedagang retail di pasar tradisional Kota Bogor dan snowball sampling untuk pelaku tataniaga yang menyuplai ke pedagang eceran. Hasil penelitian menunjukan terdapat dua saluran pemasaran yang terbentuk. Saluran I Pedagang pengumpul di Klaten dan Kulonprogo - pedagang besar Pasar Induk Kramat Jati-pedagang pengecer Pasar Tradisional Kota Bogor - konsumen akhir, saluran II Pedagang pengumpul di Grobogan - pedagang besar Pasar Induk Kramat Jati - pedagang pengecer Pasar Tradisional Kota Bogor - konsumen akhir. Nilai marjin pemasaran dan farmer’s share pada analisis efisiensi saluran pemasaran menunjukan saluran pemasaran I dan II memiliki nilai marjin total yang sama yaitu Rp. 10.000 dan  farmer’s share paling tinggi yaitu pada saluran pemasaran II sebesar 23,08%. Hasil analisis risiko distribusi dengan pendekatan Enterprise Risk Management (ERM) menunjukan risiko paling tinggi adalah susut bobot tingkat pedagang pengumpul, rusak fisik di tingkat pedagang besar dan susut bobot di tingkat pedagang pengecer
