Abstract
In the calculation of coal resource estimation is generally done by a conventional and nonconventional method. This research uses a nonconventional method of Moving Windows Statistical (MWS) and Kriging, with 3 dimensions of calculation box area 100m x 100m, 200m x 200m, and 300m x 300m. which is processed using MWS and SGems software. The value to be gained is to compare the average yield of coal thickness with basic statistics, Inverse Distance Squared (IDS) and Kriging, and estimation of coal resources. By using MWS obtained an average value of coal thickness for area 100x100 equal to 6,40m, area 200x200 equal to 6,24m, and 300x300 equal to 6,03m. For the value of its ids in the area of 100x100 of 6.38m, 200x200 area of 6.16, and 300x300 of 5.94. As for the value of Kriging using Sgems with 100x100 area of 5.77m, 200x200 of 5.68m, and 300x300 area of 5.8m. For estimation of coal resource at area 100x100 equal to 943,480ton, area 200x200 equal to 526,460ton, and area 300x300 equal to 327,450 ton. In comparison, the average value of the average thickness by basic statistics, IDS¸, and Kriging on each area did not change significantly. But the value of the kriging method is the most accurate value because of the influence of spatial variation of data where one point with the other point influences each other.

Abstract
The development of technology in the electronic field has now reached the generation of the Internet of Things (IoT). IoT is a collection of objects in the form of a physical device (hardware) that is able to exchange information between sources of information. The development of creative industries through IoT is expected to be a solution to foster entrepreneurship among students who will contribute to local and national economic development. The entrepreneurship training program in the IOT field was attended by 30 students from various study programs in the FPTK UPI environment, and they attended this activity carefully starting from the stages of preparation, implementation, apprenticeship to the partner industry until the evaluation stage. Various innovative works that combine technology with IoT utilization have been produced from the results of these training activities, including the development of smart home, automatic glass mixer with blynk, smart building and motor controller. Seeing the future challenges and the existence of these business opportunities and as an effort to develop entrepreneurship in the field of Information technology especially those based on creative industries through the use of the Inetet of Things for UPI students, this training activity is one of the means to realize economic growth both locally, regionally and internationally.

Abstract
This study aims to determine the effect of epigenetic changes on differences in human behaviour. To support the research, researchers used the ex post facto method to 7 people from 7 provinces that varied their life experiences. The results show that epigenetic changes encourage neuron function so that human behaviour changes. Human behaviour is modified by epigenetic processes, namely the more experience in the past, human behaviour is more adaptive to lifes problems. This is due to the response process of neuroendocrine in dealing with stress which makes individuals more able to reduce stress by releasing the hormone corticosterone. In short, experience in dealing with problems makes people more mature in behaving

Abstract
This study aims to determine the voltage losses on the 150 KV transmission line in Cibatu and Mandirancan Sub-systems in the PLN APB West Java region. This study utilizes the effect of the installation of Static VAR Compensator on voltage losses on a 150 KV transmission line during peak load conditions. By knowing the characteristics of the system on a channel that utilizes sensitivity to the addition of loads, the installation of SVC will have an impact on the improvement of voltage losses on the transmission network. This study uses simulations using ETAP software version 12.6. From the calculation simulation results that use the actual data of APB APB West Java in the amount of voltage loss on the channel. While based on the ETAP simulation results, there were improvements in voltage losses at Dawuan substation by 13.56%. This proves that SVC installation on transmission lines can reduce voltage losses in the Cibatu and Mandirancan Sub Systems.

Abstract
The urban air environment that has been polluted by vehicle and industrial exhaust emissions pollutants causes dry and irritated skin. Cinnamon essential oil containing cinnamaldehyde (60.72%), eugenol (17.62%) and coumarin (13.39%) functions as an antibacterial and can treat skin due to polluted air environment. Cinnamon essential oil can be used as a cream and soap ingredient. Soap and cream products can be used for skin care. Cinnamon trees are widely planted in the Subang area of West Java. This study aims to determine community empowerment in the Subang area in developing the processing of essential oils. The research was conducted by surveying the training sites of the Subang community in developing plantations of cinnamon trees and processing them by steam distillation, so that essential oils were obtained. Samples were taken purposively as many as 30 people. The results of the study show that a. through steam distillation, cinnamon essential oil is obtained, b. cinnamon tree waste such as leaves can be processed distillation into essential oils, c. Local people can practice processing essential oils as a result of training, and d. The community can develop the business of processing cinnamon essential oil independently, so that it can be used to add value to family income.

Abstract
The dominance of Indonesias youth unemployment rate is currently occupied by vocational school graduates. The incompatibility of competencies prepared in vocational schools with the competencies needed by the labour market triggers this unemployment rate. Discussion of employability skills as a basic skill is high among human resource developers. The learning process must pay attention to the profile of labour needed so that the gap can be overcome. This study aims to measure the increase in employability skills in problem solving skills of students through teaching factory model. The study sample was 60 students from vocational schools who conducted teaching factory on bread production in West Java. Improved problem solving skills are measured based on 5 indicators, are work safety, managing facilities, making decisions, knowing how to learn, and solving problems. 37 competency units are prepared based on national work standards as a guideline for measuring students problem solving skills. Achievement of employability skills in problem solving skills of students in SMKN 1 Pacet is higher than SMKN 1 Cibadak, and SMKN 2 Subang. The causes of differences in the achievement of employability skills are discussed.
