Abstract

Mathematics is the study of patterns, so in chess pattern recognition is very important in problem solving. Chess is a problem-solving instrument and the best way to analyze problem-solving because chess has clear rules in decision making, thus a skilled chess player becomes a good problem solver. Metacognitive activity and problem-solving processes are intimately intertwined. The purpose of this research is to describe the metacognition profiles of students who play chess and students who do not play chess in solving mathematical problems. This research is a qualitative-research. The research subjects in this study were students who could play chess and students who could not play chess. The criteria are students who have participated in chess matches as low as possible at the sub-district level and regularly play chess, while students who cannot play chess are students who do not understand the basics of playing chess. This research carried out in class VIII at a junior high school in Surabaya. The instruments in this study were math ability tests, problem-solving tests and interview guidelines. The data collection procedure was carried out by giving students a math problem-solving test and interviews. The data analysis technique in this study was carried out in the following steps; transcribing the subject's answers, examining the subject's answer data from interviews, data reduction, data categories, analyzing students' metacognition profiles, and drawing conclusions. The results of the study stated that the metacognitive abilities in solving problems of chess students were better than those of non-chess students. The ES subject achieved 80% of metacognitive activity indicators, while the MI subject only achieved 54.25% of metacognitive activity indicators.

Abstract

The experiment was aimed to study the effects of phosphorous and potassium fertilizers on growth and seed yield of kenaf on Latosol. The experiment was carried out at Tajur Experimental Station, IPB Bogor, from January 1991 to July 1991. The seed germination test was held in the Laboratory of Seed Science and Technology IPB, Bogor. Kenaf variety Hc-48 was used in this experiment. The two factor factorial experiment was arranged in Randomized Block Design with 3 replications. The first factor was 4 levels of phosphorous fertilizer: 0, 30, 60 and 90 kg P2O5/ha. The second factor was 3 levels of potassium fertilizer: 0, 60 and 120 kg K2O/ha. Phosphorous and potassium fertilization each increased significantly plant height, stem diameter, the number of mature and total fruit per plant, seed yield per hectar: however there were no significant effect on percentage of mature fruit, number of seeds per fruit, weight of 1,000 seeds and seed germination. The dosage of phosphorous fertilizer until 90 kg P2O5/ha still increased yield linearly, otherwise the optimum dosage of potassium fertilizer was reached on 69.31 kg K2O/ha with seed yield 2,036.48 kg/ha. There was no interaction effect between P and K fertilization.

Abstract

Snakehead fish (Channa striata) is a type of freshwater fish that contains high levels of protein albumin. The research was conducted to determine the albumin content in snakehead fish after the cooking process, both steamed and wrapped. The research was conducted using a completely randomized design with a factorial pattern, the first factor was the cooking method (steamed and wrapped) and the second was cooking time (10, 15, 20, and 20 minutes). Determination of protein albumin levels in snakehead fish after processing using the Biuret method. The steaming process for 15 minutes resulted in protein content in the snakehead fish of 0.76%, while the protein albumin that was lost was 19.28%. The wrapped method for 20 minutes has a remaining protein content of 0.59%, while the missing protein is 38.78%. The method of processing snakehead fish by steaming is better than the wrapping process.

Abstract

Regulasi diri dalam belajar merupakan kemampuan siswa untuk mengatur cara berpikir dan tindakan mereka selama proses pembelajaran. Faktor utama yang mendukung regulasi diri adalah motivasi, keyakinan, dan pengetahuan yang dimiliki siswa, yang semuanya berperan penting dalam mencapai prestasi belajar yang optimal. Studi ini bertujuan untuk menggambarkan tingkat regulasi diri siswa dalam belajar dan mengeksplorasi implikasinya terhadap layanan bimbingan dan konseling di sekolah. Desain penelitian menggunakan deskriptif kuantitatif dengan melibatkan sampel sebanyak 364 siswa dari lima Sekolah Menengah Atas (SMA) di Banda Aceh, yang dipilih menggunakan teknik Stratified Random Sampling berdasarkan rumus Slovin. Skala regulasi diri dalam belajar diukur dengan instrumen yang terdiri dari 44 item pernyataan, yang telah diuji validitas dan reliabilitasnya melalui expert judgment. Dalam studi ini, ditemukan bahwa lebih dari setengah siswa (lebih dari 50%) berada pada kategori tinggi dalam hal regulasi diri, yang artinya mereka sudah cukup mampu mengelola aspek-aspek tersebut dalam belajar. Hal ini menunjukkan bahwa sebagian besar siswa memiliki keterampilan yang baik dalam mengatur dan mengelola proses pembelajaran mereka, meskipun ada kemungkinan masih ada beberapa siswa yang membutuhkan dukungan lebih dalam mengembangkan kemampuan ini.
