Various factors causing fatigue in athletes include an increase of lactic acid in muscles. According to the movement patterns of softball athletes, the energy source comes from the Lactaid anaerobic metabolism. Therefore, it is necessary to know the elimination of lactic acid in muscles, reflecting the decrease of lactic acid in the blood. This study aimed to determine the recovery time of lactic acid levels after exercise in 0 minutes, 5 minutes, 10 minutes, and 20 minutes. Accutrend Lactacid measured softball athlete lactic acid levels. The method used in this study was an experimental method with One-Shot Case Study research design, while the research subjects were randomly assigned from the viable softball athlete population in the Student Activity Unit. The samples included 12 athletes. Data analysis employed t-test paired scores with significance p ≤ 0.05 using SPSS V. 20.0 software. The results showed that the lactic acid levels returned to normal, namely the level of 2.79 mMol/L, at 20 minutes of rest. It concludes that that lactic acid levels of softball athletes increased after the start of training, decreased after 5 minutes of rest, and returned to normal in 20 minutes of rest.

AbstrakMatematika memiliki peranan penting dalam kehidupan. Namun, dalam praktik pembelajarannya sebagian siswa masih menganggap matematika sebagai mata pelajaran yang sulit. Bukti-bukti di lapangan menunjukkan bahwa hasil belajar geometri masih rendah. Kesulitan pada materi geometri dapat berdampak pada kesulitan-kesulitan bagian lain dalam materi geometri itu sendiri, karena banyak pokok bahasan dalam geometri yang saling berhubungan. Penelitian ini bertujuan untuk mengetahui faktor penyebab kesulitan siswa dalam proses pemecahan masalah geometri berdasarkan tahapan berpikir Van Hiele serta untuk melihat ketercapaian siswa dalam pemahaman geometri berdasarkan tahapan berpikir geometri Van Hiele. Metode penelitian yang digunakan adalah metode penelitian kualitatif dengan jenis penelitian studi kasus. Subjek penelitian yang diambil sebanyak 6 siswa dari kelas VII C SMP Negeri 6 Garut. Hasil penelitian menunjukkan bahwa ketercapaian siswa pada proses pemecahan masalah geometri berdasarkan tahapan berpikir Van Hiele paling banyak adalah pada tahap 0 (visualisasi). Hal ini ditunjukkan dengan tingginya persentase pencapaian siswa pada tahap visualisasi yaitu sebanyak 96,87 %. Ketercapaian tahapan berpikir Van Hiele yang paling baik dicapai sebesar 3,13% pada tahap 1 (Analisis). Untuk tahap 2 (deduksi informal) dan tahap 3 (deduksi) belum ada siswa yang mampu mencapai tahapan tersebut. Faktor yang menjadi penyebab kesulitan siswa dalam materi segiempat disebabkan karena beberapa hal, yaitu pemahaman mengenai konsep dan sifat-sifat segiempat yang kurang, pemahaman sebelumnya mengenai materi bangun datar segiempat yang masih kurang kuat, kurangnya keterampilan menggunakan ide-ide geometri dalam memecahkan masalah matematika yang berkaitan dengan bangun segiempat, serta kondisi kelas yang kurang kondusif untuk belajar.Kata Kunci: Kesulitan siswa pada geometri, tahapan berpikir Van Hiele, Kualitatif, Studi Kasus.AbstractMathematics has an important role in life. However, in the practice of learning some students still regard mathematics as a difficult subject. The evidence in the field shows that the geometry learning result is still low. Difficulties in geometrical matter can affect the difficulties of other parts of the material itself, since many of the subjects in the geometry are interconnected. This study aims to determine the factors causing student difficulties in the process of solving geometry problems based on the stages of thinking Van Hiele and to see students' achievement in understanding geometry based on the stages of thinking geometry Van Hiele. The research method used is qualitative research method with case study research type. Research subjects taken as many as 6 students from class VII C SMP Negeri 6 Garut. The results showed that students' achievement in the process of solving geometry problems based on the stage of thinking Van Hiele at most is at stage 0 (visualization). This is indicated by the high percentage of student achievement in the visualization stage that is as much as 96.87%. The achievement of the best stage of Van Hiele thinking was achieved at 3.13% in stage 1 (Analysis). For stage 2 (informal deduction) and stage 3 (deduction) no students have been able to reach that stage. Factors that cause student difficulties in rectangular material caused by several things, namely the understanding of the concept and the characteristics of the rectangle is lacking, previous understanding of the material wake rectangular flat that is still less strong, the lack of skills to use geometric ideas in solving math problems Relating to wake up quadrilateral, as well as class conditions that are less conducive to learning.Keyword: Student difficulties on geometry, Van Hiele thinking stages, Qualitative, Case Studies.
