Director General of the World Health Organization (WHO) Tedros Adhanom Ghebreyesus officially announced the Coronavirus (Covid-19) as a pandemi on Wednesday, March 11, 2020, so all world activities changed including education. The Covid-19 pandemi has forced the learning system in schools to drastically change from face-to-face meetings to online learners. Many schools that do not yet have an online learning infrastructure are forced to do online lectures. This study aims to analyze the effectiveness of online learning during the Covid-19 Pandemi. The purpose of this research is to get information about the effectiveness of the online learning process during the Covid-19 pandemi. The research uses qualitative explorative methods with inductive approaches. In this study, respondents related to 5 people consisting of 1 principal, 1 teacher, 1 teacher in the field of science, 1 parent, and 1 student. To maintain the confidentiality of the respondent's identity, the researcher named the respondents P1, P2, P3, P4, and P5. Interviews are structured with questions that are compiled and associated and developed with related literature. The result of this study is the lack of effective online learning due to the lack of facilities and infrastructure and the unpreparedness of technology education for teachers and students.

K-Means is a non-hierarchical data clustering method that can group data into several clusters based on data similarity, so that data with the same characteristics are grouped in one cluster and data with different characteristics are grouped in another cluster. The K-Means method can be used to process various data, including for clustering in the field of education. The use of the K-Means algorithm has been widely carried out but not many activities have been handled and are only often used for selection or acceptance activities and the use of attributes that must be reproduced to get optimal results. In this study, we will review various papers that perform clustering using the K-Means method for research in the field of education. Based on our research, papers related to the use of the K-Means algorithm for clustering in education have proved feasible and useful for future research. So it can be concluded that the K-Means method has been tested to be used for clustering in the field of education and the K-Means method can be useful in many aspects of education, both having an impact on educators, students and other educational aspects.

Proses produksi Pembangkit Listrik Tenaga Uap yang menggunakan batubara sebagai sumber energi pembakarannya, menghasilkan limbah berupa fly ash dan buttom ash yang tergolong Bahan Beracun dan Berbahaya (B3). Apabila limbah batubara tidak dikelola dengan baik, akan menyebabkan pencemaran lingkungan. PT Petrokimia Gresik memiliki pembangkit listrik dengan dua unit boiler yang menggunakan batubara sebagai sumber energi pembakaran, dengan kapasitas 32 megawatt. Penelitian ini bertujuan memanfaatkan limbah fly ash batubara yang dihasilkan dari Utilitas Batubara (UBB) yang berjumlah 20 ton per hari. Data yang diperlukan dalam penelitian ini yaitu data limbah fly ash batubara dan data kebutuhan koagulan yang berasal dari data produksi. Dengan menggunakan metode reverse logistics, fly ash batubara didaur ulang menjadi koagulan padat untuk dijadikan bahan masukan di unit effluent treatment yang kemudian dapat menghasilkan air bersih untuk diproses menjadi air demin sebagai Boiler Feed Water di UBB. Fly ash dijadikan koagulan dengan cara mereaksikannya menggunakan Asam sulfat (H2SO4). Berdasarkan hasil penelitian, Rasio pencampuran optimum antara fly ash kadar Al2O3 sebesar 20,56% dengan H2SO4 1:1 dalam pembuatan koagulan didapatkan rasio 1:2. Dosis optimum pemakaian koagulan dalam penelitian ini pada air limbah di TK 6616 (neutralis water) yaitu sebesar 0,5 g/L (500 ppm) dengan penurunan turbiditas sebesar 98,68% dan penurunan TSS sebesar 97,41%. Kemudian, koagulan hasil pengelolaan dijadikan bahan masukkan di unit effluent treatment PT Petrokimia Gresik, sehingga dapat membentuk sistem closed loop pada aliran proses produksi. Potensi keuntungan dari penerapan hasil penelitian ini sebesar Rp 49.394.250 per hari.

Conarch Bangun Sejahtera is an architectural consulting company engaged in building design and building construction. High mental workload and unsuitable work system conditions cause workers to experience symptoms of work stress such as boredom at work, lack of motivation and enthusiasm for work and worries about their future careers. This study aims to determine the effect of work system components on job stress. The method used is the Macroergonomic Organizational Questionnaire Survey (MOQS) and analyzed using path analysis. This study shows that there is very significant effect of work system variables simultaneously on job stress. Work system variables partially have an influence on job stress by calculating their effective contribution, indicating that the physical environment variable contributes 7.82%, the social environment variable is 15.08%, the work condition variable is 30.53%, the organizational condition variable is 10.89%, the technology variable and work equipment is 7.14% and individual characteristic variables is 11.94%. Of the six variables, it is known that the variables that have the most influence on work stress are the conditions of work and the social environment, so suggestions are given to improve these two variables to reduce work stress.

PT. Polymindo Permata adalah perusahaan ekstrusi plastik yang memproduksi rotan sintetis. Salah satu produk fast moving andalannya adalah Viro Core Collection (VCC) yang menyumbang 50% dari total order. Defect produk VCC masih jauh lebih tinggi dari target 3%. Tujuan penelitian ini adalah untuk meningkatkan kualitas dan mengurangi waste dengan pendekatan sistematis menggunakan metode Fault Tree Analysis (FTA), analisis faktor dan analisis perbandingan. Hasil diagram Pareto menunjukan penyebab cacat tertinggi adalah warna belang mencapai 23.24 % dari total produk cacat. Hasil analisis FTA dan analisis faktor diketahui faktor penyebab defect warna belang disebabkan karena metode mixing material untuk mesin Co-extruder setiap Setter yang berbeda-beda, ekstrusi material IHMB menggunakan mesin Single Screw Extruder, sistem mesin Co-extruder tidak berfungsi maksimal, dan Heater tidak berfungsi maksimal. Setelah improvement diterapkan kemudian dilakukan analisis perbandingan Independent-Sample T-Test. Hasil penelitian menunjukkan bahwa metode mixing material untuk mesin Co-extruder setiap Setter yang berbeda-beda sebelum ada SOP dibanding setelah ada SOP berbeda signifikan, sehingga faktor ini adalah paling dominan untuk meningkatkan kualitas dan menurunkan defect.
PT. Polymindo gem是一种生产合成藤条的塑料产品的压缩机公司。其中一个快速移动的产品是Viro Core Collection (VCC)，占总订单的50%。VCC产品的Defect仍远高于目标3%。本研究的目的是通过使用错误树分析(FTA Tree Analysis)、因子分析和比较分析系统的系统方法提高浪费时间和减少浪费。帕雷托图显示，瑕疵的最大原因是总体缺陷中黄色达到23.24%。由于自由贸易协定协定的分析和已知的因素因素，导致条纹色素性缺陷的原因是，不同的点火装置的物料混合机、IHMB材料挤压机使用单螺旋排气机、联合排气机系统不能正常工作，而加热器不能正常工作。植入后进行了独立样本测试比较分析。研究结果表明，在汤之前，对共导体机的材料混合方法与汤之后的每一个个体都有不同的意义，因此，这一因素在提高质量和降低缺陷方面是最重要的。

Polymindo Permata adalah perusahaan ekstrusi plastik yang memproduksi rotan sintetis. Salah satu produk fast moving andalannya adalah Viro Core Collection (VCC) yang menyumbang 50% dari total order. Defect produk VCC masih jauh lebih tinggi dari target 3%. Tujuan penelitian ini adalah untuk meningkatkan kualitas dan mengurangi waste dengan pendekatan sistematis menggunakan metode Fault Tree Analysis (FTA), analisis faktor dan analisis perbandingan. Hasil diagram Pareto menunjukan penyebab cacat tertinggi adalah warna belang mencapai 23.24 % dari total produk cacat. Hasil analisis FTA dan analisis faktor diketahui faktor penyebab defect warna belang disebabkan karena metode mixing material untuk mesin Co-extruder setiap Setter yang berbeda-beda, ekstrusi material IHMB menggunakan mesin Single Screw Extruder, sistem mesin Co-extruder tidak berfungsi maksimal, dan Heater tidak berfungsi maksimal. Setelah improvement diterapkan kemudian dilakukan analisis perbandingan Independent-Sample T-Test. Hasil penelitian menunjukkan bahwa metode mixing material untuk mesin Co-extruder setiap Setter yang berbeda-beda sebelum ada SOP dibanding setelah ada SOP berbeda signifikan, sehingga faktor ini adalah paling dominan untuk meningkatkan kualitas dan menurunkan defect.","PeriodicalId":13714,"journal":{"name":"Intech","volume":"7 1","pages":"23-29"},"PeriodicalIF":0.0,"publicationDate":"2021-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88912434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
