In recent years, minimization of logistics and transportation costs has become essential for manufacturing companies to increase profits. One thing is done to reduce logistics and transportation costs by optimizing the route of taking or transporting components from each supplier. Route optimization to minimize total transportation costs is a problem that often finds in Vehicle Routing Problems (VRP). Problem Capacitated Vehicle Routing with Time Windows (CVRPTW) is one variant of VRP that considers the vehicle capacity and the service period of each vehicle. CVRPTW is a Non-Polynomial Hard (NP-Hard) problem that requires an efficient and effective algorithm in solving problems that occur in this automotive company. This study uses the Ant Colony Optimization (ACO) algorithm by testing using several parameters to solve the CVRPTW problem. The test results using the ACO algorithm obtained a faster route compared to the method applied by the company.

This reseach aimed to measure the mental workload of data entry processing tasks in the e-commerce industry based on mental workload value. It was to determine the factors influencing mental workload mainly induced by the data entry process. The experiments without work instruction and with two types of work instruction were conducted to diagnose the mental workload. The measurement of the initial mental workload condition of data entry employees was conducted in the laboratory. Then, the Electroencephalogram (EEG) measurement using sensors from Emotiv was performed every 30 minutes, and the data of EEG measurements (focus, engagement, and stress) were collected using the laptop. Meanwhile, pulse measurement (heart rate) was measured before and after the work. Raw National Aeronautics and Space Administration Task Load Index (NASA-TLX) and reaction time measurement were conducted after the work. Through these experiments, the researchers identify that mental effort and fatigue are the significant determinants of mental workload value in the data entry process of the e-commerce industry. In respect of the results of work performance analysis, it is recommended that the placement of work instruction should be near the employee. Then, the task demand (minimum completion target) should be adjusted according to each employee’s capacity.

Tofu industry, which consider as a small and medium scale industry (UMKM), use a lot of water in its production process. In order to increase its profit, they need to increase the efficiency of clean water usage. One method is through recycling the wastage water into a clean water so it can be used in the production process. In order to recycle the wastage water, people make use of a passive filter to reduce the dissolved solid and acidity in wastage water so it can be similar with fresh water. From the results of our experiment, an average of 30 litres of recycled water can be used in the production process which reflect to increment efficiency of 5% per day in production process. Therefore, as an impact of the economy, this water recycling process will reduce the production cost of making tofu using of recycled water. And from the social aspect it affects the reduction of fresh water from the ground and reduce odours that will occur in environment.

The commercial synthesis of fatty acid esters of glycerol is important because it can be used for other derivative production varieties. This research aims to construct the quality monitoring system for esterification condition faster and more efficient for the production of esterification glycerol. The monitoring systems were based on the measurement parameters from two inputs LED mid IR 3,4 and 5,5 μm sensors that using the data acquisition with computer database via USB 2.0 using Arduino Leonardo microcontroller and classifying the esterification quality condition using the classification method K-Nearest Neighborhood (KNN) The purpose of KNN method is to classify the variations of parameter inputs from the LED mid IR sensors in quality monitoring. In this research the condition of esterification was divided into three conditions: not good, fair,good., these classification was trained and tested in Orange Software for data mining using receiver operating characteristic (ROC) curve that is a graphical plot that illustrates the excellent performance of a classifier system for esterification condition with AUC . In application for quality monitoring, the influence of various parameters such as temperature set in the reactor has relation to the quality of product. By using this system, we obtained the optimum process conditions is 200oC and time needed for the process was 200 minutes.

Dalam penelitian ini, film tipis material feroelektrik Barium Zirkonium Titanat (BaZr0,5Ti0,5O3) disintesis dan pengaruh variasi suhu annealing terhadap sifat optiknya dipelajari. Film tipis BaZr0,5Ti0,5O3 ditumbuhkan di atas substrat Silikon (Si (100)) menggunakan metode Chemical Solution Deposition (CSD) dengan bantuan perangkat spin coater. Film tipis yang telah dibuat kemudian di-annealing pada tiga suhu berbeda (750 oC, 800 oC dan 850 oC). Karakterisasi sifat optik dari film tipis yang telah dibuat dilakukan menggunakan Spektrometer Ultraviolet-Visible (UV-Vis) Ocean Optics USB4000. Hasil karakterisasi menunjukkan bahwa film tipis BaZr0,5Ti0,5O3 yang dibuat memiliki nilai reflektansi yang tinggi pada panjang gelombang cahaya tampak dan nilai koefisien absorbansi yang tinggi pada panjang gelombang cahaya ultraviolet (UV). Nilai bandgap pada masing-masing film tipis BaZr0,5Ti0,5O3 dengan suhu annealing 750 oC, 800 oC dan 850 oC adalah 3,04 eV, 3,07 eV dan 3,22 eV. Semakin tinggi suhu annealing maka semakin tinggi nilai bandgap yang dihasilkan. Dari hasil yang diperoleh, terlihat bahwa film tipis BaZr0,5Ti0,5O3 yang dihasilkan memiliki sifat semikonduktor dan berpotensi digunakan sebagai sensor atau komponen elektronik yang bekerja memanfaatkan energi pada panjang gelombang cahaya ultraviolet.

Work fatigue is an important aspect and is very influential in determining the level of accidents, especially motorbike accidents. According to WHO, almost 30% of all deaths due to road accidents involve two- and three-wheeled motorized vehicles, such as motorbikes, mopeds, scooters and electric bicycles (e-bikes), and the number continues to increase. Motorcycles dominate road deaths in many low- and middle-income countries, where nine out of ten traffic accident deaths occur among motorcyclists, as in Indonesia. However, until now, in Indonesia, there has been no monitoring system capable of identifying fatigue in motorbike drivers in the transportation sector. This research aims to determine fatigue patterns based on driver working hours and create a sensor system to monitor fatigue measurements in real-time to reduce the number of accidents. The research began with processing questionnaire data with Pearson correlation, which showed a close relationship between driver fatigue and driving time and a close relationship between fatigue and increased heart rate and sweating levels. From calibration tests with an error of 3% and direct measurements of working conditions, it was found that two-wheeled vehicle driver fatigue occurs after 2-3 hours of work. With a measurement system using the Box Whiskers analysis method, respondents' working conditions can also be determined, which are divided into 4 zones, namely zone 1 (initial condition or good condition), zone 2 a declining condition, zone 3 a tired condition and zone 4 is a resting condition. Hopefully, this research will identify fatigue zones correctly and reduce the number of accidents because it can identify tired drivers so they do not have to force themselves to continue working and driving their motorbikes. As a conclusion from this research, a measurement system using two sensors, such as ECG and GSR can identify work fatigue zones well and is expected to reduce the number of accidents due to work fatigue.
