Students are required to learn and develop themselves independently and actively find the source of knowledge, not just getting knowledge from the lecturers alone. One type of motivation is intrinsic motivation. Intrinsic motivation can be in the form of satisfaction in undergoing learning and gaining knowledge, the existence of appreciation of the achievements achieved, and the existence of life goals to be achieved. Thus it is necessary to do research to predict student learning performance by considering the intrinsic motivation of students. Primary data was obtained from the motivational questionnaire of 100 students, while secondary data includes attendance data, quiz data, assignments, mid-term exam, and final exam. Furthermore, the two types of data are combined. The first stage uses the Logistics Regression Algorithm, Support Vector Classifier, Decision Tree, Random Forest, Gaussian NaÃ¯ve Bayes, and K-Nearest Neighbors. The quality of the algorithm is measured using the level of accuracy. Cross validation test with 5 K-Fold was carried out, and the Decision Tree algorithm was obtained with the highest yield of 0.898051. The second stage is to do a tuning hyperparameter using a Grid Search and obtained a value of 0.927206. The third stage is to predict data test as much as 21 data and obtained accuracy of 0.904761.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139338857","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}

Penelitian ini dilakukan untuk menganalisis penyebab tingkat cacat pada proses produksi. Six sigma menjadi metode yang digunakan bersama untuk mengendalikan kualitas produk. Dari hasil analisis yang dilakukan, terdapat empat jenis cacat pada produksi yaitu cacat material, visualÂ not good, dan grinding surface not good. Hasil pada tahap measure diketahui bahwa tingkat sigma perusahaan sebesar 4.24 yang berarti sudah berada diatas nilai rata-rata perusahaan Indonesia. Dari hasil perhitungan yang disajikan pada diagam pareto diketahui bahwa cacat visual not good memiliki nilai kumulatif yang paling tinggi yaitu 41.6%. Penyebab terjadinya defect yang didapat dari brainstorming dikarenakan area kerja kurang nyaman, penyimpanan bekas kaleng cat tercampur dengan material lain, raw material terkena oli, pengerjaan tidak memerhatikan SOP, skill pekerja tidak merata, dan kondisi mesin yang tidak prima. Pembersihan setiap proses produksi mulai dari bahan mentah hingga produk jadi, penekanan pada SOP, penjadwalan pemeliharaan preventif pada setiap mesin, dan pelatihan pekerja secara berkala merupakan solusi yang disarankan untuk mengatasi cacat tersebut.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139339640","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}

PT Petrokimia Gresik has implemented noise control and started implementing several elements/components of the Hearing Conservation Program (HCP)/Hearing Conservation Program (PKP) to control noise. However, the PKP special program has not been implemented systematically, only a few elements/components have been implemented. The research objective was to determine the mapping and noise level in the factory area in the IB department of PT Petrokimia Gresik using the Noise Mapping and Niosh methods. Based on the results of measurements in the field, there are 11 highest noise points which are above the noise level quality standard of Regulation Number Per.13/Men/X/2011 before control is carried out. The highest noise point is 106 dB at point 10. Based on noise level measurements, the length of exposure recommended by NIOSH varies, and depends on the measurement results obtained the longest exposure time allowed at point 10 is 34.2 minutes. This measurement point is closest to the noise source, so workers are required to use PPE in the form of ear plugs, ear muffs and safety hats. The PPE can reduce the amount of acoustic energy on the hearing mechanism of workers at PT Petrokimia Gresik.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139339899","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}

The method to be used is the Job Safety Analysis (JSA) method because this method focuses on identifying hazards in the work, then the hazards will be controlled by the Hazard Identification And Risk Control (HIRARC) method. From the analysis using the JSA method, 8 jobs were found to be at risk with an average risk level of Medium - High so risk control is needed for these 8 jobs. The work will be analyzed for hazards and controlled risks, the goal is to know the magnitude of the risk of work and prioritize controlling which jobs have the most significant risk and if possible, replace machines that are still manual with automatic machines to be more efficient, reduce risk and do not require many people.","PeriodicalId":17758,"journal":{"name":"Jurnal Serambi Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139340274","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}

This corn sheller machine can replace the use of fossil raw materials and electricity with solar power and obtain faster, more ergonomic product results. The data required in this study are body dimension data or shoulder height anthropometry in an upright standing position to determine the height of the corn sheller that will be done standing when the farmer does the corn shelling process. With the existence of a solar-powered corn sheller machine, it is expected to be more productive than before.
