This study was conducted to determine the causes and location of student difficulties in solving mathematical problems with HOTS based on the mathematical connection skills they have. This research using qualitative methods, and was conducted in the even semester of the 2017/2018 academic year at STKIP Campus Santu Paulus Ruteng. The research subjects were selected using purposive sampling technique. The selected items were three students of the STKIP Santu Paulus Ruteng Mathematics Education Study Program, with categories namely one student capable of deep mathematical connections, one student capable of moderate mathematical connections, and one student capable of high mathematical connections. The selection of subjects from each of these categories is based on the results of the identification of problems that have been carried out during the initial observation. The instrument in this study was the researchers themselves. Besides, researchers use supporting instruments, namely tests and guidelines for interviews. In conducting interviews, researchers conduct structured and unstructured interviews. The technique of data collection is done by giving written tests and interviews conducted through the triangulation process. The triangulation process aims to obtain valid data carried out by conducting repeated interviews at different times to the same research subject. The interval between the first phase of the interview with the next stage is 14 days, and because the data is saturated, so the data collection stops. Data analysis is carried out when data collection takes place, and after data collection is carried out. The steps in analyzing the data using the Miles and Huberman analysis models, namely 1) reducing data, 2) presenting data, and 3) concluding. The results showed that, in solving mathematical problems with Hots, the subject of KKMR only relied on factual knowledge but had difficulties in using conceptual, procedural and metalogical knowledge, while the KKMS subject could only use factual and procedural knowledge but had difficulty using procedural knowledge and metacognition, while KKMT subjects only had difficulty in using their metalogical knowledge but did not experience difficulties in using factual, conceptual and procedural knowledge. Learning difficulties experienced by each subject are caused because they do not often practice mathematical solving with Hots when learning mathematics.

The purpose of this study was to determine whether or not there is an effect of a scientific learning approach with local wisdom on students' mathematics learning achievement. The population were students of class II SMPN I Ruteng-Cancar for the 2018/2019 academic year. The sample was determined by random class. There were 64 students who were divided into two treatment groups. A total of 32 students in the experimental class and 32 students in the control class. The difference in effect between experimental action (scientific learning with local wisdom) and control action (conventional learning) is seen in the average difference test between these two groups. Data analysis used statistical t test, in which the sample groups are mutually independent. Obtained, tcount = 3,21 and ttable = 1,67. Because t_count > t_table then Ho: µ1 ≤ µ2 is rejected, otherwise H1: µ1 > µ2 is accepted. The conclusion is that learning with a scientific approach containing local wisdom has a positive and significant effect on student achievement.

AbstractThis research was conducted to see the independence of student learning in the Basic Mathematics course in participating in distance learning, especially online learning during the Covid-19 Pandemic. This is a quantitative-descriptive study with 85 first-year students of the Agricultural Socio-Economic Study Program of the Indonesian Catholic University, Santu Paulus Ruteng, with a focus on studying the learning independence of students who take online learning due to the Covid-19 Pandemic situation. The results showed 18.82% of students had low learning independence, while 81.18% of students had high learning independence. Furthermore, in semi-structured interviews, it was found that students initially experienced difficulties in adapting to changes in learning habits, limited learning resources in the network, and a lack of interaction between students and lecturers. This limitation encourages students to be more independent in learning, which can be seen from more than 70% of students who have set learning goals, learning strategies, being able to manage study time, and conduct self-evaluation of the learning process that has been followed. More than 80% of students determine a learning environment that supports a learning atmosphere and seek help from classmates.Keywords: independent learning, Covid-19 pandemic, distance learning.

Tomatoes are one of the most commonly cultivated vegetables. This vegetable is multipurpose, especially as a daily cooking spice, a raw material for tomato sauce, and has a delicious and slightly sour taste. Considering its still low production, it is necessary to develop cultivation efforts to increase its yield. This study aims to determine the effect of different planting distances on the growth and yield of tomato plants (Solanum lycopersicum L). The research was conducted in La'o Village, Wali Subdistrict, Langke Rembong District, Manggarai Regency, East Nusa Tenggara, from April to July 2024. The method used in this study was a Randomized Block Design, consisting of 4 treatment levels: J1: 50x40 cm, J2: 50x50 cm, J3: 40x30 cm, and J4: 40x40 cm. Each treatment level was repeated 4 times, resulting in 16 experimental units. Each experimental unit contained 10 plants, with a total of 160 plants. Observations were made by examining 5 sample plants per experimental unit, with a total of 80 sample plants. The parameters observed in this study included: plant height (cm), number of leaves (blades), number of branches, flowering age (days), stem diameter (mm), number of harvested fruits (g), and fruit harvest weight (g). The data obtained were analyzed using Analysis of Variance (ANOVA) or F test at the 5% level. If significant differences were found, Duncan's Multiple Range Test was conducted at the 5% level. Research results show that various planting distances do not have a significant effect on all parameters. The ideal planting distance for tomato plants is observed with the following treatments: J3 (40 x 30 cm) for plant height, J2 (50 x 50 cm) for the number of leaves, J1 (50 x 40 cm) for flowering age, stem diameter, and J4 (40 x 40 cm) for the fresh weight of harvested fruit.
