Purpose: The main objective of this research is optimal use of customer segmentation using the Recency, Frequency and Monetary (RFM) approach so that companies can better understand and comprehend the needs of each customer. By carrying out this segmentation, companies can communicate better and provide services tailored to each customer.
Methods: The K-means algorithm is used as the main method for customer segmentation in this research. This research uses a dataset of online retail customers. Apart from that, this research also uses the elbow method to help determine the best number of clusters to be created by the model.
Result: Based on the elbow method, the most optimal is to use 3 clusters for this case. Thus, in K-means modeling, forming 3 clusters is the best choice. Clusters produce groups of customers who have specific characteristics in each cluster. The analysis shows that quantity and unit price have a significant influence on online retail customer behavior.
Novelty: This research strengthens the trend of using the K-means algorithm for customer segmentation in online retail datasets, which has proven popular in journals from 2018 to 2022. This research creates 3 new variables that will be used by the model to understand the characteristics of customer transaction behavior. This study also emphasizes the importance of exploratory data analysis in understanding data before clustering and the use of the elbow method to determine the most appropriate number of clusters, providing a significant contribution in analyzing customer segmentation.

This research aims to find out: how baggage carried by passengers is not free from various problems with baggage service deviations, which usually occur when passengers arrive at the final destination station or during post-flight service, this can be one of the performance benchmarks for a ground handling company. , whether it is good or not in providing service to passengers. In this case, the role of the loading master officer plays an important role in the process of loading and unloading cargo, preventing unwanted things from happening. This study used qualitative research methods. The data collection techniques used were, observation, interviews, documents, and documentation along with observations. The researcher directly carried out observations, the researcher also explained the results of the data taken during interviews and observations. For the interview, the researcher interviewed the Loading Master officer 3 sources with document data obtained by the researcher. from documentation of the activities of Loading Master officers when carrying out their duties and responsibilities in the field and also in the form of implementation documents for the data analysis techniques used, namely data collection, data reduction, data presentation, discussion, and conclusions.  
The role of Loading Master officers is very important at Adi Soemarmo Solo Airport, both from the implementation of standard operational procedures and also influences improving the performance of Loading Master officers for air cargo handlers. Not only that, researchers also found that Loading Master officers are very fast in Loading-Unloading if officers are slow or if you are not careful during the Loading-Unloading process, it will result in the plane being delayed.

The learning that has been carried out so far in the school tends to apply classical learning techniques that do not pay attention to the stages in the variety of learning. For this reason, a good way is needed to learn a lesson, one of which is known as a learning technique. In this research activity, the theme of mathematics learning for school children is based on the KUMON method. This technique is considered one of the solutions that is expected to increase children's academic values and awareness in learning and train children to have independence and full responsibility in the learning process. Indirectly, when repeating the material done by the child, the child will get a reinforcement value that is more than the material conveyed Repetition is intended to provide added value in learning a new material and is implicit in the hierarchical structure of the material that has been learned so that it will be self-absorbed when the child is faced with a problem that establishes a relationship to relates the past material to the future material. the regression analysis test using simple linear regression analysis with the general form of the equation formed is as follows: Y = 0.099X + 36.823. Where the learning variable affects the bound variable of learning outcomes of 0.099 and the value of the constant when no one variable influences, it will produce a learning outcome value of 36, 823. hypothesis test proved to be accepted and the null hypothesis was rejected from the results of the calculation of the value of t obtained was t calculated 6.796 greater than t tabel = 0.697 and sig = 0.763 > sig 0.05, it can be proven that the learning variable has a positive and significant effect on the learning outcome variable.

This research aims to determine the use of accounting information systems, viral marketing, and the tagline "free shipping" on online impulse buying among consumers. This research uses a quantitative type of research. The population in this study were students in Solo Raya. Sample selection used accidental sampling technique, with a sample size of 100 respondents. The data sources used are primary and secondary data. The data collection method uses a questionnaire or questionnaire. This research uses data analysis methods, namely descriptive statistical analysis, data quality testing, and classical assumption testing. The research results state that the accounting information system has a significant effect on online impulse buying among consumers, viral marketing has a significant effect on online impulse buying among consumers, and the tagline "free shipping" has a significant effect on online impulse buying among consumers.

Ibu hamil rentan terhadap COVID-19 karena mengalami penurunan sistem kekebalan tubuh dan perubahan fisiologis selama kehamilan, serta risiko yang meningkat jika memiliki penyakit bawaan seperti hipertensi atau diabetes. Namun, kesibukan kerja sering membuat ibu hamil jarang memeriksakan diri untuk itu tujuan penelitian ini adalah mengetahui hubungan antara jenis pekerjaan ibu hamil dengan status komorbiditas selama pandemi COVID-19 di Puskesmas Suruh. Metode yang digunakan adalah kuantitatif crossectional. Sejumlah 124 partisipan didapatkan dengan menggunakan teknik total sampling. Data dikumpulkan dengan menggunakan Lembar Checklist. Variabel pada penelitian ini adalah jenis pekerjaan dan status komorbiditas. Teknik analisis yang digunakan yaitu analisa univariate dan bivariate. Hasil penelitian menunjukkan bahwa tidak ada hubungan yang signifikan antara jenis pekerjaan dengan komorbiditas ibu hamil.

Pengalaman keluarga mendampingi anggota keluarganya yang sakit dapat memunculkan kondisi seperti stres, kecemasan hingga depresi. Kondisi ini akan berdampak pada proses perawatan dan pengambilan keputusan tindakan pada pasien. Situasi ini akan berbeda pada satu individu dengan individu lainnya. Tujuan: Penelitian ini mendeskripsikan tingkat DAS pada keluarga selama masa tunggu pasien rawat inap di Rumah Sakit. Metode: Penelitian menggunakan metode deskriptif kuantitatif. Populasi penelitian adalah keluarga pasien yang anggota keluarganya dirawat inap di rumah sakit. Jumlah sampel ditentukan menggunakan accidental sampling dan didapatkan total 100 responden. Penelitian ini telah dilakukan pada tanggal 5 – 23 Mei 2023 di Rumah Sakit dr. Asmir Salatiga, Kota Salatiga. Instrumen penelitian menggunakan kuesioner Depression Anxiety Stress Scale 21 (DASS-21). Hasil: Pada penelitian ini didapatkan hasil tingkat depresi responden 67% normal, tingkat stres responden 73% normal dan tingkat ansietas responden 49% normal. Kesimpulan: Tingkat depresi dan stres keluarga pasien sebagian besar lebih dari 50% normal sementara tingkat ansietas keluarga pasien kurang dari 50% yang normal. Sehingga dapat diartikan bawah pada penelitian ini selama masa tunggu keluarga pasien lebih mengalami kondisi ansietas dari pada stres dan depresi.
