This research was conducted to achieve improving the quality of service to members, for this reason, a service quality analysis method is needed. Here the methods needed are Service Quality (Servqual) and Importance Performance Analysis (IPA) methods. The purpose of this study is to identify the level of customer satisfaction with service quality by the CUBG Tp Cooperative. Pamulang, to find out what aspects are supporting the improvement of service quality and to provide recommendations for improvements or revisions that are prioritized to improve service quality at the CUBG Tp Cooperative. Pamulang. This research method is quantitative descriptive analysis using Servqual and Importance Performance Analysis (IPA) methods. The results of this study are the level of satisfaction of cooperative members using the Customer Satisfaction Index (CSI) method with a percentage of 86.05%. Based on the calculation of Servqual Analysis of 5 dimensions, namely Tangibility (physical evidence), Reliability (Reliability), Responsiveness (Awareness / responsiveness), Assurance (Guarantee) and Empathy (Empathy) represented by 25 attributes obtained if members of the CUBG Cooperative TP.Pamulang have been satisfied with the Servqual provided by the CUBG Cooperative Tp.Pamulang, this is shown in the average gap between expectations and reality of 0.05

The spread of the Covid-19 virus globally continues to grow. The impact felt by Indonesia in addition to the many positive cases, economic, social and educational system problems. The learning process that has been carried out face-to-face has become undisturbed, so that the learning process changes its function to online learning. The purpose of this research is to obtain information on how to describe the implementation process of learning for students of the Pamulang University Mathematics Study Program during the Covid-19 pandemic as an effort for Higher Education to stop and break the chain of spreading covid-19. The research subjects were students of the Mathematics Study Program. Data processing was carried out by interviewing through cloud meetings and questionnaire response sheets using the google format. Interviews and questionnaire sheets were conducted with questions that were compiled and developed with related literature. Miles & Huberman's interactive analysis techniques were used in this study. This study obtained the results, namely, (1) students already have basic learning facilities such as leptops, computers, android-based mobile phones and internet networks; (2) The learning process has not been maximally carried out yet; (3) Lack of supervision from both lecturers and parents during the lecture or learning process; (4) The online learning process has the advantage of flexibility in time, encourages and trains students to study independently.

The purpose of this study was to determine the level of damage that occurred and also to determine the factors that cause damage to the production. By using statistical aids in the form of check sheets, p control charts, histograms, and cause and effect diagrams. Starting with a check sheet to collect data to make it more neat and structured, the next step is to enter the data into histogram form to make it easier to present the data, then calculate using a p control chart to find out whether the damage is still within the control limits or not, then make a cause and effect diagram. to find out what factors cause damage to PT. Sami Putrians Group. The results of the analysis show that the damage is outside the control limits, this is shown in the results of the calculation of the damage with the criteria of dirty materials and missed stitches which still have points that are outside the UCL limit. The cause-and-effect diagram gives results regarding the factors that cause the most dominant damage, namely humans due to lack of thoroughness, lack of skills, lack of motivation, lack of firmness and lack of discipline, the second cause is material caused by the material used is below standard, the third is the environment because the environment is lacking comfortable and lack of lighting, the last is the engine factor because it is not carried out routine and appropriate maintenance on the machine used.Keywords: Check sheet, Diagram, Control chart.

Salah satu acuan penting suatu lembaga pendidikan dalam meningkatkan kualitasnya adalah dengan meningkatkan proses pembelajaran di sekolah. Indikator keberhasilan dalam proses pembelajaran dapat diamati dari kepuasan peserta didik dalam melaksanakan pembelajaran. Terjadinya perubahan proses pembelajaran yang dilakukan disekolah SMK/MA Al-Manar sebelum dan setelah pandemi COVID-19 berdampak secara tidak langsung terhadap kepuasan peserta didik. Salah satu metode yang dapat digunakan untuk menganalisa kepuasan adalah dengan Metode Servqual dan IPA. Metode Servqual digunakan untuk mengidentifikasi kebutuhan peseta didik dan kesuksesan layanan yang diberikan sekolah dan dijadikan acuan untuk menyusun strategi baru dalam memberikan pelayanan yang maksimal kepada peserta didik. Penelitian ini merupakan penelitian deskriptif dengan menggunakan survey. Servqual menggunakan skala likert dengan kisaran 1 (Stronglydisagree) hingga 5 (stronglyagree). Data yang dikumpulkan terdiri dari data primer dan sekunder. Berdasarkan nilai CSI-nya yaitu sebesar 64,24553, maka dapat disimpulkan bahwa siswa SMK/MA Al Manar cukup puas terhadap kualitas pelayanan dalam proses pembelajaran pasca pandemi COVID-19. Terdapat 6 Faktor yang berada di kuadran I yang artinya harapannya masih lebih tinggi dibandingkan kenyataan, 1 faktor di kuadran II yang sesuai harapan, 4 faktor di kuadran III yang artinya harapan dan kenyataannya sama-sama rendah dan terdapat 4 faktor yang kenyataaanya melebihi harapan

This paper aimed to determine factors that affect significantly of parental interest in Islamic Boarding Schools. The subjects of the study were parents of students at Tahfidz Daarul Quran, an Islamic boarding school in Tangerang. A binary logistic regression model was used to analyze the association between parental interest and some covariates namely volition, needs, motivation, knowledge and school environment with used software R. The results showed that a binary logistic model combining knowledge and school environment provides the best model as the significance values of 5.02e-05 and 1.53e-04 are still 0.05 smaller and the wald values are 16.440 and 14.335 which are greater than 3,841. The coefficient estimation of the knowledge variable is 0.246 with an odds-ratio value exp (0.246) = 1.27. This means that parents who have a knowledge of Islamic boarding schools of 1.27 times more interested than do not have knowledge. Furthermore, the coefficient estimation of the school environment is 0.234 with an odds ratio value exp (0.234) = 1.26. It means that parents are more interested 1.26 times in a good school environment than in a bad school environment. So, knowledge and school environment are factors that greatly influence parents' concerns when choosing an Islamic boarding school.
