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.","PeriodicalId":13714,"journal":{"name":"Intech","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82002120","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}

Percetakan tersebut mempunyai beberapa permasalahan terkait kondisi kerja serta belum adanya kesadaran dalam menerapkan Keselamatan dan Kesehatan Kerja (K3) di tempat kerja. Tujuan penelitian ini adalah melakukan evaluasi kondisi kerja serta merancang usulan perbaikan untuk kondisi kerja yang lebih produktif dan sesuai dengan pedoman K3 di percetakan XYZ. Program Work Improvement in Small Enterprises (WISE) dengan pendekatan Participatory Action Oriented Training (PAOT) dilakukan dengan melibatkan partisipasi aktif dari pemilik usaha serta pekerja dalam melakukan evaluasi kondisi kerja, pembuatan rencana aksi perbaikan serta implementasi usulan perbaikan. Hasil evaluasi kondisi kerja menggunakan daftar periksa WISE, menunjukkan terdapat 13 elemen periksa yang membutuhkan suatu usulan perbaikan. Melalui metode focus group discussion (FGD) didapatkan hasil bahwa perbaikan yang akan diprioritaskan untuk diimplementasikan dalam waktu dekat adalah 4 elemen periksa karena mempertimbangkan faktor biaya, waktu, dan sumber daya manusia di lapangan. Perbaikan pertama adalah pembuatan jadwal rutin untuk pemeriksaan mesin serta jaringan kabel listrik dengan penerapan 5R. Perbaikan kedua adalah pembuatan tanda bahaya pencegahan kebakaran. Perbaikan ketiga adalah pembuatan tanda himbauan pemakaian pelindung diri masker dan sarung tangan. Perbaikan keempat adalah pembuatan label untuk menuliskan identitas produk sehingga memudahkan pekerja mengenali produk yang berada di area penyimpanan. Evaluasi serta usulan perbaikan kondisi kerja tersebut dapat membantu UMKM dalam meningkatkan kesadaran akan K3 dan mengurangi risiko terjadinya kecelakaan kerja.","PeriodicalId":13714,"journal":{"name":"Intech","volume":"111 1","pages":"45-55"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79197725","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}

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.","PeriodicalId":13714,"journal":{"name":"Intech","volume":"93 1","pages":"39-44"},"PeriodicalIF":0.0,"publicationDate":"2021-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73324793","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}

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.","PeriodicalId":13714,"journal":{"name":"Intech","volume":"1 1","pages":"30-38"},"PeriodicalIF":0.0,"publicationDate":"2021-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88835756","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}

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.
