    The rapid advancement of computers and the internet has led to the emergence of internet language as a prominent linguistic phenomenon. Exploring the distinctive features of this language has become an important area of study in recent years. This research analyzes the typical features of internet language used by men and women commenters on Instagram, with a particular emphasis on gender-based differences. The study investigates ten common digital language features: multiple punctuation marks, unconventional spelling, capitalization, asterisks for emphasis, written-out laughter, music/noise references, action descriptions, emoticons, abbreviations, and rebus writing. These features serve as the basis for data analysis. A qualitative approach is used to examine the collected data in-depth. The findings reveal that while both genders use capital letters (though not in all caps) and multiple punctuation marks (such as exclamation points and periods), women employ more internet language features overall—42 features compared to 31 by men. Additionally, woman users are more likely to extend consonants in their spelling, whereas men tend to repeat vowels. These differences illustrate how users modify language for efficiency and self-expression in digital communication

    River borders are natural areas that need to maintain their primary function but currently tend to change into artificial areas, which are used for human activities and building construction. Limited urban land and economic factors are likely the causes of people building in river border areas. This study aims to analyze the function of buildings that are not by the use of space on river borders so that they can be used as a reference for controlling spatial planning. Building and river data are needed to assess the level of consistency and inconsistency of buildings in river border areas. The level of inconsistency is calculated based on the number of buildings located in the river border area divided by the number of buildings outside the river border. The results of the building consistency index analysis of 0.87 indicate that the majority of buildings in Padang City tend to be outside the river border area. However, there are still many buildings that are inconsistent with land use regulations, namely those located in river border areas. The Sungai Pisang watershed is recorded as the most erratic, even though it has the fewest buildings. On the other hand, although the Batang Arau watershed has the largest number of buildings, it shows a lower inconsistency value than the Sungai Pisang watershed and Air Timbulun watershed.Sempadan sungai merupakan lahan alami yang perlu dipertahankan fungsi utamanya, namun saat ini cenderung berubah menjadi lahan buatan, yang dimanfaatkan untuk tempat aktivitas manusia dan mendirikan bangunan. Terbatasnya lahan perkotaan dan faktor ekonomi kemungkinan menjadi penyebab masyarakat membangun di area sempadan sungai. Penelitian ini bertujuan menganalisis fungsi bangunan-bangunan yang tidak sesuai dengan pemanfaatan ruang pada sempadan sungai untuk dapat dimanfaatkan sebagai acuan pengendalian pemanfaatan ruang. Data bangunan dan sungai dibutuhkan untuk menilai tingkat konsistensi dan inkonsistensi bangunan pada kawasan sempadan sungai. Tingkat inkonsistensi dihitung berdasarkan jumlah bangunan yang berada pada kawasan sempadan sungai dibagi jumlah bangunan yang berada diluar sempadan sungai. Hasil analisis Indeks konsistensi bangunan sebesar 0,87 menunjukkan bahwa mayoritas bangunan di Kota Padang cenderung berada di luar kawasan sempadan sungai. Namun, masih ada sejumlah bangunan yang tidak konsisten dengan aturan peruntukan lahan, yakni terletak di kawasan sempadan sungai. DAS Sungai Pisang tercatat sebagai DAS yang paling tidak konsisten, meskipun jumlah bangunannya paling sedikit. Sebaliknya, DAS Batang Arau, meskipun memiliki jumlah bangunan terbanyak, menunjukkan nilai inkonsistensi yang lebih rendah dibandingkan DAS Sungai Pisang dan DAS Air Timbulun. &nbsp

In order to accomplish their objectives, businesses constantly look for resources that can work efficiently and effectively. Human resources that are both competent and perform well can be a boon to a company\u27s bottom line, while those that are neither can lead to financial disaster. An approach based on quantitative methods is employed. The foundation of this rests on statistical studies and data collected from a specific demographic. Asking people specific questions is the backbone of the quantitative approach, which aims to verify hypotheses through data collection. With 42 participants, 42 degrees of autonomy, and a t-table and a signifance level 0f 0.005, the results for the two-way test are 2.018. Following from the previous summary, We can a meaningful association between compensation employee performance because the t-count (5.431) is larger than the t-table (2.018) and the sig value (0.000) is less than 0.05. Therefore, we reject Ho and accept Ha. With a total sample size of 42, a degree of autonomy (db) of 42 for two-way weighing, and a significance level of 0.05, we get the following t-table: 2.018. According to the summary, the t-count (4.688) is higher the t-table (2.018), and the sig value (0.001) is less than 0.05. Therefore, can reject Ho and accept Ha, indicating a significant relationship between employee motivation and job performance. Compensation should be based on what employees deserve if the company wants to see improved performance from its employees. Giving out awards to deserving employees is another way for the company to boost performance; it makes them feel appreciated, which in turn motivates them to work harder.

This study aims to determine the perception of teachers in Indonesia (elementary school teachers, junior high school teachers and senior high school teachers) on the importance of inclusive teaching in learning. This research is a survey study conducted on teachers in Indonesia, with random sampling. The sample number of teachers who were respondents was 46 teachers. To obtain data, researchers used an instrument in the form of a questionnaire in the form of a Likert scale with five scales and yes or no questions. As additional data, researchers conducted interviews conducted on several samples of teachers. The data obtained is then analyzed quantitatively and poured into tables and graphs. From the results of the analysis, it is known that teachers attach great importance to inclusive teaching. 82.61% teachers argue that inclusive teaching is a good idea. However, in reality, the application of inclusive teaching has not been optimal. One of the obstacles in optimizing the application of inclusive teaching is the selection of appropriate learning strategies in inclusion classes. This is what needs to be explored in order to find appropriate learning strategies for inclusion classes

    This study aims to describe the creative thinking ability of seventh grade junior high school students in applying the concept of division and identify the factors that cause creative thinking difficulties in that context. This research is based on the importance of understanding mathematical concepts, where creative thinking becomes the foundation in helping students overcome difficulties in understanding the concept of division. The method used was qualitative with an explorative approach. Participants were selected using a purposive sampling technique, focusing on learners who were considered to be able to provide in-depth insights into their creative thinking abilities and the difficulties they faced. The results showed that learners were generally able to generate ideas quickly (fluency) and connect concepts with solutions in a relevant manner, although there were some ideas that were less relevant. Most learners also show flexibility by using various methods in solving problems, but there are some who tend to use only one method. In terms of originality, unique and structured ideas were found, although some were less structured or unable to develop ideas completely. In terms of elaboration, some learners were able to detail ideas well, while others showed weaknesses in detailing and developing ideas. Factors that cause creative thinking difficulties include lack of understanding of basic concepts, limitations in connecting prior knowledge, lack of practice and time, low level of confidence, lack of practice in working on open-ended problems, learning methods that do not support creativity, and lack of motivation
