Abstract

This study aims to analyze the algebraic problem-solving abilities of student package B equivalence. Data collection was conducted on students of package B equivalency at the Community Learning Activity Center (PKBM) of Rahmatan Lil-Alamin Makassar, South Sulawesi. The method used in this research is quantitative. The results of the study showed that 45% of students who completed, while students who did not complete were 55%, meaning that there were more students who did not complete than completed. Students' classical completeness also gets a percentage of 40%, it means that students do not complete classically. The students have not been able to understand algebraic problem and students experience concept errors and problem solving procedures. Students must be trained to do algebraic questions more routinely and students are also given algebraic questions related to the context of students' daily life. The research is needed to be done further on other variables such as conceptual understanding, problem solving errors, as well as material to be tested such as geometry, arithmetic, and statistics.

Abstract

This study aims to formulate a pattern of spatial linkages between provinces in Indonesia based on the amount of bank financing through the influencing factors, namely third-party funds (DPK), Non-Performing Financing (NPF), MSME financing loans and GRDP. The data used is 2021 data. By using the Spatial Regression method with Moran' s I Test, it will look for relationships and inter-regional (spatial) relationships in the amount of bank financing based on the observed factors. From the results of data analysis, the Moran's I value obtained is 0.4439. Then based on the test results |2,2444|>1.96, the decision making according to the existing hypothesis is H0 rejected. It can be concluded that there are spatial dependencies between provinces based on the amount of bank financing in each province according to the observed factors, namely DPK, NPF, MSME financing credit and GRDP. The expected output in implementing this developed strategy is to increase the amount of banking financing that is evenly distributed in each province in order to achieve the objectives from the economic aspect while taking into account the benefits for banking institutions. The improvement in the economic aspects in question includes increasing the usability of money, increasing the usability of goods, maintaining the country's economic stability and as a bridge to increase national income.

Abstract

Education statistics subject is one of the compulsory subjects for students majoring in education which is often avoided by many students. Students tend to have a negative attitude towards subjects related to numbers and calculations. Based on the observation results of Arabic Language Education student exam results, there are still many students who have not been able to describe or analyze the results of data processing. Thus, research was conducted regarding the interest and motivation of Arabic Language Education students in the Education Statistics subject. The research method used is the questionnaire method to measure aspects of interest and talent, aspects of learning readiness, and learning support facilities. So the results obtained from the study were that 85.7% of students liked the Education Statistics subject, and prepared the media to record material well. The presence of lecturers in the room also affects student enthusiasm for learning. It's just that the enthusiasm for student learning has not been supported by adequate facilities.

Abstract

Population data is useful as planning material in making various policies, including avoiding imbalances between the number of health facilities and services and the population in an area as well as other facilities such as schools, markets, and other public facilities. Ordinary differential equations of exponential and logistic models are used in modeling population dynamics in Bulukumba Regency to obtain population estimates until 2030. The determination of the future population of Bulukumba Regency is based on the growth rate and capacity obtained using the exponential and logistic approaches. The results obtained show that the estimation using the exponential model and the logistic model estimation for 2015-2019 are close to the data from the Central Bureau of Statistics. However, the logistic model is more accurate than the exponential model which is more significantly close to the data from BPS. So that the results of the logistic model are better than the exponential. The logistic model assumes that Bulukumba Regency has a capacity of K = 450000, while the exponential model assumes that the population increases exponentially.

The main objective of this research is to obtain data related to differentiated learning for introverted and extroverted students in vocational education/Vocational High Schools (SMK). The research carried out is a type of qualitative research with a case study approach. The data collection techniques used in this research were interviews and documentation. The questions will develop and be more open but still have the same focus. The interviews conducted in this research included interviews with 4 students as subjects chosen by students in class X of SMK Negeri 3 Tarakan. There were 4 participants in this research, namely 2 introverted students and 2 extroverted students, based on the considerations of guidance and counseling educators. The documentation used in this research is field note documents from guidance and counseling teachers as well as reports on the results of observations of the learning process. The Miles and Huberman model is used to analyze data with data reduction, data display, and conclusion drawing/verification analysis steps. The results of differentiated learning research must be adjusted to students' learning needs, especially students with introverted and extroverted personalities. Good activities and responsibilities can be used to design differentiated learning with a process and content approach. The product approach can also be used for students with introverted and extroverted personalities from the aspect of expressiveness. Meanwhile, the environmental approach can be applied to students with introverted and extroverted personalities by mapping the comfortable environment when studying and doing assignments individually or in groups.
