Urban farming (gardening in the middle of the city) is increasingly in demand by modern society. Urban farming provides business opportunities as well as being a lifestyle trend. One of the plants that can be cultivated at home is oyster mushroom. Oyster mushroom cultivation is quite easy but requires a special environment to grow up. To do mushroom cultivation at home, it is necessary to manage temperature and humidity to achieve optimal temperature and humidity. A temperature and humidity control system that can be monitored and controlled through the smartphoneis the result of the study. Temperature and humidity detected by the DHT22 sensor, then read by NodeMCU and sent to the Blynk application via a WiFi connection are considered as the input system. WiFi used by NodeMCU is the same as WiFi used by smartphones. Blynk on a smartphone will display the temperature and humidity read by NodeMCU. If the temperature and humidity are out of the optimal temperature and humidity range for oyster mushrooms, a notification will appear on the smartphone. Temperature and humidity control can be done by pressing the ON / OFF button on Blynk to turn on and turn off the lights or the fan as needed, so that the temperature and humidity return to optimal. Based on testing, the system successfully displays temperature and humidity on a smartphone, displays notifications and makes control. The relative error of the temperature measurement is 2.6% and the relative error of the humidity measurement is 3.2%.

PT.BFM is a leading wheat mill in Indonesia and is also the first and largest producer wheat flour producer in Indonesia. This factory is very concerned about the quality of its products so the engineer must provide services by maintaining the machine to meet customer demand and maintain product quality well. To maintain customer confidence on the part of the engineer certainly must pay attention to the process of maintaining the machine itself, because the machine used must have waste. This study aims to identify waste and provide recommendations for improvement that aim to reduce the waste that occurs. By using the Lean Concept approach which is more dominant towards Lean Manufacturing and Six Sigma, so that this research can combine waste reduction with quality control using the DMAIC stage. That way the machine maintenance process can improve efficiency and improve quality. The study began by describing the Big Picture Mapping and weighting of waste values based on a questionnaire using VALSAT. Waste was also identified using FMEA to calculate the critical value of waste then a recommendation for improvement was carried out using 5W + 1H. Calculation results from processing data from data that has been collected, it was found that the total processing time which was previously 76,895 seconds to 57,342,497 seconds. The results of Value Added Activity are 85.233%, Non-Necessary Value Adding is 8.67% and Non-Value Added is 6.10%. FMEA analysis results obtained that critical waste that needs improvement is waste waiting with a score of 160

Coconut commodity has a strategic value because it has an important role in the economy, society and culture of Indonesian society. Coconut plant is a multipurpose plant where all parts of the plant have economic value, one of which is coconut husk. The potential of coconut coir is very large and has not been used optimally. Whereas coconut coir, when processed, will produce various products such as home industries, furniture, geotextiles, boards, and creative industries. This study is aimed at analyzing the potential development of the coconut coir processing industry and the added value that will be generated using the case study method and the location selection is done deliberately (purposive sampling). The business financial feasibility model obtained is a predictive model for analysis and planning of business financial feasibility through the NPV, IRR, PBP, BCR criteria with various scenarios of changes in prices, interest rates, and production scale.The business balance model obtained is a predictive model that can be used to analyze the price gap level to plan the price level that will provide proportional profit to produce coconut coir processing factory business. Based on the results of the verification of the model with input using the assumption of parameter values, it shows that the coconut coir processing industry is feasible to run.

Pak Utar Tofu Factory is a conventional home industry which is engaged in the production of Tofu. There are three types of tofu produced, namely White Tofu, Chinese Tofu, and Jambi Tofu. In plain view, it can be seen that the work stations at this plant are still less ergonomic and have a very high risk of Musculoskeletal Disorders (MSDs) injury, therefore the authors conducted research by applying two methods namely Rapid Entire Body Assessment (REBA), and Ovako Working Analysis System (OWAS) for further comparison. Both methods have the viewpoint of the researcher, as well as the worker's perspective, and are used to examine each work station. After observation, there were 6 work stations with a total of 27 activities in total. After conducting research with these three methods, it was found that the REBA method resulted in all work stations having to be repaired, and the OWAS method resulting in all stations having to be improved. After reviewing and seeing the results of the two methods at each work station, the authors made improvements to the design of work tools at work station two because the work station did not have a major effect on the procedure of the work operator, compared to other work stations. The author makes a work tool repair plan at work station 1 which was originally dipped, into a water flush.

PT. Pola Gondola Adiperkasa is a company engaged in construction, whose main activities are gondola maintenance and gondola installation. According to an interview conducted with PT. Pola Gondola Adiperkasa, it is known that this company has problems in unstructured inventory. If the gondola spare part inventory is stored for a long time then the problem that occurs is the reduced quality of the goods. This causes the inventory cost to increase. The purpose of this study is to determine the calculation of the Economic Order Quantity (EOQ) method, to know the calculation of the Min-Max method and to propose improvements regarding inventory control. The results of calculations using the Economic Order Quantity (EOQ) method were found to be more efficient in terms of controlling the gondola spare part inventory compared to PT. Pola Gondola Adiperkasa and Min-Max method. The difference between the policies of PT. Pola Gondola Adiperkasa with Economic Order Quantity (EOQ) method is Rp. 384,787, while the difference between the policies of PT. Pola Gondola Adiperkasa with the Min-Max method is Rp.268.931. Researchers propose to PT. Pola Gondola Adiperkasa to use the Economic Order Quantity method.

This study was conducted to determine the physiological workload and psychological employee mental burden of making clothes at each work station. The study was conducted at six work stations that work station QC Jodoh, Linking, QC Lampu, Pantek, Sontek and Obras. Calculation of physiological workload carried using the NASA-TLX. Physiological workload calculation results showed that the highest energy consumption experienced by the operator at the work station sontek (85,8 Kcal /hour), while the lowest value contained in the work station QC Jodoh (54 Kcal/hour). This job classified into light workload due to smaller than 100-200 Kcal/hour (according to Decree No. 5 1of 1999). Measurement of psychological workload on each carrier based questionnaire NASA-TLX which has been filled by 18 operators, obtained a total rating of each indicator psychological workloads different. This shows that the difference in the psychological workload experienced by the operator on each indicator.

Metode pengukuran beban kerja mental meliputi metode objektif dan subyektif. Metode pengukuran beban kerja mental secara subyektif yang banyak diaplikasikan di Indonesia adalah NASA TLX (Task Load Index). NASA TLX adalah pengukuran subyektif yang bersifat multidimensional (multidimensional scalling) yang relative membutuhkan waktu dalam aplikasinya. Penelitian ini bertujuan untuk mengukur beban kerja mental tenaga medis, dalam hal ini mahasiswa Jurusan Keperawatan FIKES UPN Veteran Jakarta pada proses injeksi dengan menggunakan metode pengukuran NASA TLX. Dengan diketahui beban kerja mental ini diharapkan dapat bermanfaat untuk merumuskan tindakan-tindakan yang diperlukan untuk menguranginya. Nilai rata-rata NASA – TLX didapatkan hasil sebesar 80.1, dimana nilai skor > 80 yang menyatakan bahwa beban kerja mental proses injeksi pada mahasiswa merupakan pekerjaan yang berat
