Abstract

Neck pain radiating to the upper trapezius muscles can interfere with the patient's daily activities due to the limited range of motion of the neck, the cervical extensors and flexors become tense due to changes in cervical biomechanics and generally affect workers who require repetition of movements coupled with high work speeds. If you hold your head down for too long it will cause muscle tension or spasm in the neck area and there will be limited neck movement so that the neck is functionally disturbed. The purpose of this study was to determine the effectiveness of muscle energy techniques in neck muscle pain, spasm of the upper travezius muscles. The design of this study was experimental with a pre test-post test one group design. The research subjects met the criteria, namely neck pain myofascial trigger point of the upper trapezius muscle, men and women with moderate to severe pain intensity, willing to be respondents and no musculoskeletal disorders. This research was conducted in June-July 2018. 10 patients with upper trapezius pain (age 21-23 years) were given muscle energy techniques with minimal isometric contractions and stretching 3 times/week, isometric movements repeated 5 times and stretching on the upper trapezius for 45 second. Pain was measured with a Visual analog scale at the beginning and end of the intervention. The results of the study found a significant reduction in pain with scores (p <0.05). The conclusion of this study is that muscle energy technique is effective in reducing pain in cases of spasm of the upper travezius muscle.

Abstract

“Gresik Stainless Steel Industry is one of the largest stainless steel factories in Indonesia since 1996 until now. With a sufficiently large production capacity, it is possible for the production process to produce emissions/by-products that can pollute the environment. This study approaches the production process of the Gresik Stainless Steel Industry using the Life Cycle Assessment (LCA) method. The scope of this research is gate to gate or during the stainless steel production process from the entry of materials to the release of finished products which include operating units from Coil Preparation Line Units, Coil Grinding Line Units, Mill Units, Annealing Pickling Line Units, Skinpass Units, Slitter Units , to Cut-To-Length Units. Life cycle assessment is carried out using the midpoint approach of the TRACI 2.1 method. Based on the results of the analysis, the APL unit is the operating unit that has the greatest influence on the eutrophication impact which has a total normalized value of 5025.309. This is due to the use of nitric acid as the main ingredient in the acidification process for the stainless steel production process.”

Abstract

Garbage and water are two important things for human life. Water is one of the natural resources needed by all living things in the world, both humans, animals and plants. Therefore, it must be protected and preserved so that it is not contaminated. One type of pollution is placing garbage close to groundwater sources so that it produces leachate which contaminates the soil. Sidoarjo has a TPS Sambibulu which is a temporary storage area for waste that uses open land because there is no solution to divert it, before finally being disposed of in the Jabon TPA. The location is Jalan Sambibulu, Sambibulu Village, Sidoarjo Regency, East Java 61257. This TPS serves 8,466 people. The average amount of TPS waste is 1024 kg/day, consisting of 39% inorganic waste and 61% organic waste. The purpose of this work is to determine the soil water content in the wells around the TPS with the parameters tested, namely. ammonia (NH3), phosphate (PO), organic matter (KMnO) and groundwater pH at several distances from TPS Sambibulu, and identification. the spread of waste pollution from TPS to groundwater. Based on the results of the study it is known that the majority of pollutant at TPS 0 m, 10 m, 50 m and 100 m exceed PP RI No. 82 of 2001 and PERMENKES RI no. 92/MENKES/PER/IV/2010, but the concentration values of all parameters at a distance of 100 meters from TPS meet the approved quality standards.

Abstract

The learning process for vocational higher education applies a composition of 30 percent theory and 70 percent practice. A larger composition of practical learning will guarantee an increase in the quality of students' expertise, because in practical learning students practice in workshops that produce workpieces in the form of products that have economic value. Workpieces are made by manufacturing processes using industrial-based machines such as lathes, milling machines, drills, grinders, and others. Practical work in the workshop is carried out for one week or the equivalent of 38 hours. The quality of the workpiece is also a parameter for student assessment which will become one of the semester graduation requirements so as to produce quality students in their fields. However, there are problems in practicum activities in the vocational field that are most experienced by almost all vocational education institutions, namely workpiece waste. Vaccination education managers must think about how to optimize or utilize work objects resulting from student practice. Not a few students' work is ignored or thrown away and not utilized. This is the background of this research. This study aims to make mechanical device products that have economic value by utilizing students' work. The product manufacturing method begins with data collection, planning and drawing, the manufacturing process, assembling, and testing. From the results of the tool making, 4 types of prototype products were obtained, namely table vise, bending tools, C clamps, mini press tools. From the four products made, it can be concluded that the tool manufacturing process went according to plan and optimal results were obtained.
