This study aims to analyze the use of Bloom's Taxonomy in identifying the difficulty level of questions in mathematics in elementary schools. Bloom's taxonomy is a classification framework used to classify learning objectives into six different levels, namely knowledge, understanding, application, analysis, synthesis, and evaluation. The research subjects were 15 students in class V at SDN Karet 2, Tangerang Regency. The research method used was content analysis, in which questions in mathematics textbooks for elementary schools were analyzed based on Bloom's Taxonomy categories. The data collected included the difficulty level of the questions based on Bloom's taxonomy and the distribution of the difficulty levels of the questions in mathematics textbooks. The results showed that the level of difficulty of the questions in mathematics in elementary schools varied and could be classified based on Bloom's taxonomy. Most of the items focus on levels of knowledge and understanding, with a few items testing students' abilities to apply, analyze, synthesize, and evaluate mathematical concepts. This shows that there is a tendency to emphasize understanding concepts rather than applying concepts in learning mathematics in elementary schools.

This study aims to determine the effect of organizational capital on the firm life cycle. The sample used is a manufacturing company listed on the Indonesia Stock Exchange for the 2009-2017 period, with a total of 580 observations of data from 116 companies and using a purposive sampling method. This study uses the independent variable organization capital which is proxied by OC/TA and the dependent variable company life cycle which is proxied by the dummy life cycle classification based on cash flow, retained earnings to total assets, and retained earnings to total equity. In addition, the control variables used are company size, market-to-book ratio, leverage, return on equity, company sales growth, capital expenditure, and asset turnover ratio. The analysis technique used is multinomial logistic regression. The results showed that organizational capital has a significant effect on the firm life cycle, where companies with high organizational capital are in the introduction and decline stages, while companies with low organizational capital are in the growth and maturity stages. Development requires quality human resources (HR). This human resource can act as a factor of labor production that can master technology so as to increase economic productivity. To achieve quality human resources requires the formation of human capital (human capital). The formation of this human capital is a way to obtain a number of people who have strong characters who can be used as important capital in development. This character can be in the form of level of expertise and level of community education. The concept of human capital investment that supports economic growth has existed since the days of Adam Smith (1776), Heinrich Von Thunen (1875) and other classical theorists before the 19th century who emphasized the importance of investment. human skills. Schultz (1961) and Deninson (1962) then showed that the development of the education sector with human resources as its core focus has contributed directly to a country's economic growth, through increasing the skills and productive capabilities of the workforce.  These findings and perspectives have stimulated the interest of a number of experts to research the economic value of education (Nurulpaik, 2005). Human capital is a stock of productive abilities and knowledge found in society. Alfred Marshal once said "the most valuable of all capital is that invested in human beings" (Becker, 1975). In this case human capital is a long-term investment in the development of human resources to increase productivity. The importance of human capital is that the knowledge that exists in human resources is the driving base in increasing productivity. Human capital can be distinguished from human resources management, but can also synergize. Human capital views humans more as intangible assets and human resources management views humans as costs or costs that are detrimental to the company. The concept of human capital emerged, due to a shift in the role of human resources. Human capital arises from the idea that humans are assets that have many advantages, namely human capabilities when used and disseminated will not decrease but increase both for the individual concerned and for the organization, humans are able to transform data into meaningful information. The concept of innovation has been continuously developed by a number of experts and institutions in the last 50 years. This is based on Resource Based Theory (Barney, 1991). In the perspective of Resource Based View (RBV), internal resources and the internal environment are the main keys for determining strategies to achieve high performance (Hitt et al., 2011). Resource Based Theory (RBT) focuses on the concept of attributes of excellence that are difficult to imitate as a source of superior performance and competitive advantage (Barney, 1991). Resources based theory is the company's resources as the main driver behind the company's performance and competitiveness. Based on this resources based theory, an organization can be assessed as a collection of physical resources, human resources, and organizational resources (Barney, 1991). Barney (1991) categorizes three types of resources: Physical capital resources (technology, plant and equipment) Human capital capital (training, experience, and insight), and Organizational resource capital (formal structure)

Church planting is not a new thing in the journey of Christianity and has an important role to play in the continuation of God's work on earth. Church planting is one aspect that plays an important role in the growth of the church as well as something that the church must do, not only the church, but all believers, considering this duty and responsibility is contained in the Great Commission. David Garrison suggests 4 classifications of church planting, namely rapidly multiplying, indigenous, church planting and in tribal groups. The segmentation of church planting is aimed at both unbelievers and believers who are immature in faith and unshepherded. In new church planting, the above are important factors that will help new churches grow and develop well. However, the sociological factors seen in new church planting vary depending on the case being analyzed, but God does not ignore the physical needs of people. When Jesus ministered in the world, He performed many social acts, such as healing diseases and feeding people. Evangelism is not one of our efforts to separate them from their culture, we still live culturally and maintain that culture, but our job is to straighten their path from the wrong to the right path, namely the Lord Jesus Christ who is the Savior of mankind. We must keep and preserve the culture, but it is the wrong way and understanding that we must correct.

Archiving is a process or activity that starts from creation, receipt, collection, regulation, control, maintenance, care, and storage as well as evaluation according to a certain predetermined system. As time goes by and also the many activities that have been carried out at PT Pelindo IV (Persero) Balikpapan Branch, more and more archives have been created. The purpose of this study was to find out the causes of archive management and to find out the efforts made in overcoming obstacles to archive management in the HR and general division at PT Pelindo IV (Persero) Balikpapan Branch. The type of research used in this research is descriptive research with a qualitative approach in which data is collected through observations, interviews, and documentation. Based on the research results, several things can be improved for more efficiency and effectiveness in archiving 1) What can be improved is the system currently used. Pelindo IV (Persero) Balikpapan Branch, namely the system regarding this is quite good, it's just that in recovering it is still difficult to find because letters are in other classification sections such as payment archives in the information system classification. 2) Tools and equipment used in managing archives are wooden and glass cabinets. The arrangement is still disorganized because the order folders are just piled up. The archive storage space is too small so many archives accumulate and cannot be put in the cupboard. 3) There are still many archives whose duration of archive destruction is too long, considering the number of incoming documents or document production is quite high and quite a lot because archives that are old and no longer needed will be destroyed within a yearly period.

The rapid growth of e-commerce in Indonesia has generated a massive and continuous volume of product reviews. This user-generated content is vital for business intelligence, yet its sheer scale makes manual analysis inefficient, subjective, and practically impossible. Automated sentiment analysis is therefore crucial for businesses to efficiently understand customer feedback and market perception. This research addresses this gap by implementing the Naïve Bayes Classifier (NBC) algorithm to automatically classify the sentiment of Indonesian-language e-commerce product reviews. This study utilized a dataset of 2,000 reviews collected from a major e-commerce platform's "Electronics" category. The data underwent critical text preprocessing stages (case folding, tokenizing, stopword removal, and stemming using the Sastrawi library) to handle the complexities of informal Indonesian text. The dataset was split using an 80/20 ratio, resulting in 1,600 training reviews and 400 testing reviews. Model performance was then evaluated using a Confusion Matrix, focusing on the key metrics of Accuracy, Precision, and Recall. The test results showed excellent performance, achieving an Accuracy of 90.00%, Precision of 91.93%, and Recall of 95.00%. These results demonstrate that the Naïve Bayes algorithm, when supported by robust preprocessing, is a highly effective, reliable, and computationally efficient method for this task, providing a valuable tool for e-commerce stakeholders.
