In this study, one-dimensional cutting pattern is discussed. This includes fulfilling demands for some items with different lengths by cutting some stocks of standard length available. In this problem, the patterns – the way the standard length is cut – is obtained in such an optimal ways that the trim loss becomes as minimum as possible. The decision variables are the amount of the standard lengths cut according to certain patterns. Then the problem is formulated into a linear programming model. Due to very large number of the variables and restriction to integers, the problem is the type of large scale linear integer programming. For simplicity, restriction to integer is dropped. Then the very large number of the variables is handled by considering only the favorable cutting patterns; list of all possibleways in which a standard stock may be cut is not needed. The favorable cutting pattern is then generated by using column generation technique by solving auxiliary problem in the form of a knapsack problem. The integer optimal solution is obtained by rounding it upward

Small industry is one important component in national economic structure, because it can absorb a lot of manpower and a lot of exploiting the potential of natural resources abundant in Indonesia. The number of small industries in Indonesia is quite a lot, but has not been matched by much higher performance. Therefore the number of small industries which are so muchslower average growth and is difficult to compete with large industrial products and imported products. Industry performance is one of the criteria used to measure industry growth. With performance measurement-performance small industry and handicraft villages can be foundin different areas of industry map homeland. During the performance measurement industry is based only on financial aspects. Performance measurement of the financial aspect is important, but still there are other aspects that are also important and need attention because theyaffect the performance of the industry, namely: aspects of customer (market), internal business processes and learning and growth. Therefore it is necessary for measuring the performance of various aspects of small scale industries so that their performance can be evaluated and formulated a model maintenance and development of small industries and handicraft villages are more comprehensive. The method used is the Balanced Scorecard (BSC) and Analytical Hierarchy Process (AHP). The Balanced Scorecard measures the performance of the business / industry with 4 perspective, financial, customer, business process within the company, and the process of learning and growth. Method of Analytical Hierarchy Process (AHP) is used to embobot each perspective and each Critical Success Factor. Research results showed that the average performance of small industries in Trowulan Pasuruan Stone Statue of 2083 (category enough). There are 2 perspectives of a very large weight on the performance of a stone statue of a small industry of financial and customer. Moderate success factors have great influence on both perspectives is the total asset turn over the tattoo and the number of new customers.

Perguruan tinggi senantiasa melakukan pembenahan berkelanjutan untuk memperbaiki kualitas mahasiswa. Pembenahan secara berkelanjutan ini mengharuskan mahasiswa beradaptasi dengan tuntutan akademik yang berubah mengikuti perkembangan zaman.Perubahan model pembelajaran ini mempengaruhi kondisi mental mahasiswa. Ditandai dengan munculnya indikasi beban mental seperti rasa lelah, cemas bahkan stres. Dalam beberapa penelitian, terjadinya beban kerja mental diduga dipengaruhi oleh faktor kemampuan mahasiswa dalam melakukan manajemen waktu. Tujuan penelitian ini adalah untuk mengetahui korelasi antara manajemen waktu dengan tingkat beban kerja mental pada model perkuliahan luring dan model perkuliahan daring. Penelitian ini menggunakan sampel sebanyak 76 orang mahasiswa program studi teknik industri UPN Veteran Jawa Timur angkatan 2018 dan 2019. Teknik analisis yang digunakan adalah uji korelasi dan uji beda. Untuk hasil uji beda dengan uji wilcoxon dan tingkat kepercayaan 95% ditemukan bahwa terdapat perbedaan yang signifikan antara kinerja manajemen waktu pada model perkuliahan tatap muka (luring) dengan manajemen waktu pada model perkuliahan jarak jauh (daring). Berdasarkan hasil analisis korelasi Spearsman’s diperoleh koefisien korelasi sebesar -0,365 yang menunjukan adanya korelasi lemah antara manajemen waktu pada perkuliahan luring (XL) dan tingkat beban kerja mental (Y). Sedangkan koefisien korelasi sebesar -0,752 menunjukkan adanya korelasi yang kuat antara manajemen waktu pada perkuliahan daring (XD) dengan tingkat beban kerja mental (Y) Nilai koefisien korelasi negatif memiliki arti bahwa terdapat hubungan tidak searah yang signifikan antara variabel bebas dengan variabel terikat, dimana semakin menurunnya kinerja manajemen waktu (X) maka tingkat beban kerja mental (Y) akan semakin meningkat begitu pula sebaliknya.

Many companies still do not prioritize occupational health and safety, causing a large workload to be borne both physically and mentally. It affects the workers ' fatigue and will affect performance. Work fatigue is a symptom associated with decreased work efficiency, skills, boredom, and increased anxiety. PT. XYZ is a manufacturing company, which produce refractory stone from clay as the main raw material. The production process uses human-machine power, lack of rest time, overtime to achieve production targets, repetitive and standing work, and a long-distance between milling stations and raw material processing. A few people only carry out the final part of the process. With this problem, this study uses Cardiovascular Load and Bourdon Wiersma to slow down worker fatigue and is expected to help measure worker fatigue to provide a solution in slowing down worker fatigue. The number of samples used as many as 20 workers. The results obtained from the analysis of this work system are shift one and shift two have different levels of fatigue, namely shift one high category and shift two low categories, as well as the mental load shift one is low while shift two is high, therefore shift one needs to be the improvement in his physical load while shift two needs to improve his mental load. Corrective actions that can be taken in shift one are to increase the rest time from 45 minutes to 60 minutes, implement a worker rolling system, and improve workplace conditions to make it more ergonomic. Corrective actions that can be taken in shift two are providing music, arranging work shifts such as rolling shifts, and adding rest periods.
