Abstract

Manusia dalam melakukan aktivitas kerja terkadang membutuhkan alat atau fasilitas yang dapat mempermudah dalam melakukan setiap kegiatan maupun pekerjaannya. Permasalahannya adalah beberapa operator sering mengeluhkan kondisi fisik pada saat melakukan pekerjaan disebabkan kursi kerja yang mereka gunakan tidak sesuai dengan dimensi tubuh operator, yang pada akhirnya memengaruhi produktivitas/kinerja operator. Tujuan penelitian ini adalah mengidentifikasi keluhan rasa sakit yang timbul pada bagian tubuh operator kerja bagian penjahitan, menentukan dimensi tubuh operator kerja penjahitan yang digunakan untuk usulan perbaikan kursi kerja, dan usulan perbaikan kursi kerja yang didapatkan dari hasil pengamatan kursi kerja sebelumnya. Pendekatan antropometri, kuisioner nordic body map, dan Catia V5R19 digunakan untuk perbaikan kursi kerja operator penjahitan tersebut. Terdapat beberapa pekerja mengeluh adanya rasa sakit pada bagian leher, lengan atas, bagian tangan, serta bagian kaki kanan yang berkaitan dengan sendi terasa nyeri. Perbaikan kursi kerja berdasarkan data antropometri adalah dimensi tinggi popliteal untuk tinggi kaki kursi kerja adalah 45 cm, dimensi pantat popliteal untuk panjang alas kursi kerja adalah 52 cm, dimensi lebar pinggul untuk lebar alas kursi kerja adalah 34 cm, dimensi tinggi bahu posisi duduk untuk tinggi sandaran kursi kerja adalah 60 cm, dimensi lebar bahu untuk lebar sandaran kursi kerja adalah 48 cm, dimensi tinggi siku duduk untuk tinggi penyangga tangan adalah 24 cm. Usulan perbaikan kursi kerja berdasarkan hasil pengamatan kursi kerja sebelumnya adalah adanya sandaran punggung, bantalan leher, penyangga tangan, serta pemakaian bahan tambahan seperti busa supaya lebih lunak yang itu semua dibuat untuk mengurangi resiko keluhan-keluhan fisik pada operator pada saat melakukan pekerjaan penjahitan airbag. Kata kunci: Kursi kerja, nordic body map, antropometri, Catia V5R19

Abstract

Lean supply chain is an approach used by various parties that are interconnected to achieve targets in the supply chain, useful to continuously increase customer satisfaction and to reduce processes that have no added value. Problems that occur in the process of loading and unloading fish in UKM Camar Laut South Jakarta are still a lot of waste, including the uncertainty of product delivery time, the number of excess transportation activities and the existence of defects in the product. These problems can be solved using a lean supply chain approach with Waste Assessment Model tools. The purpose is to identify the highest type of waste, determine the value added (VA); non value added (NVA); necessary non value added (NNVA) by using VALSAT tools selected and provide improvement suggestions. The highest type of waste that occurs is a defect of 20,278%. Based on the selected VALSAT tools namely process activity mapping tools, VA is 63.888%; NVA is 25,606%; NNVA is 10.512%. Proposed improvements in the process of loading and unloading fish are unnecessary process removals, warehouse integration, improvements to UKM management. Based on the creation of future state value stream mapping, there was an increase in the percentage value of value added by 8.078%, a decrease in the percentage of non value added value of 9.222% and an increase in the percentage of the value of necessary non value added of 1.143%.

Abstract

PDCA (Plan-do- check-action)is a management concept used to achieve continuous improvement in an organization. The problem that occurs in quality control is how to reduce the level of product defectscrude palm oil.The aim of this research is to identify types of defects that often occur, identify factors that cause defects in products and implement product quality improvementscrude palm oil(CPO) at PT. BPSJ with approach Plan-Do-Check-Action(PDCA). In the Pareto diagram, there are three types of biggest defects in crude palm oil products, namely the high ALB content defect type with a percentage of 39%, while for water content the percentage is 33% and for impurity content it is 29%. Factors causing defects in crude palm oil products(crude palm oil) based on fishbonecaused by several factors. Defects at high ALB levels are caused by five main factors, one of which is the human factor, namely the lack of accuracy during operations from operators/employees. Defects at high water content are caused by the main factor that the raw materials obtained do not comply with fruit acceptance standards. Defects at high levels of dirt are caused by one factor, namely the work environment, where cleanliness is not maintained in the sorting and production areas. Based on the results of implementing improvements made in an effort to increase the quality of crude palm oil products(crude palm oil)namely reducing the number of defects in crude palm oil products. The number of defects obtained before repairs were carried out for ALB levels was 52 samples to 42 samples, water content was 44 samples to 27 samples and dirt content was 39 samples to 25 samples.

Abstract

Fire is one of the incidents that disturbs homeowners because of the fire that will drain property and can claim lives when there is a lack of anticipation and minimal ignorance of the incident, such as when a fire occurs there is no early warning to the homeowner, this is also a cause of fire. The cause of the fire can be caused by a gas leak, electrical short circuit or caused by the community itself. Based on these problems, a solution is needed to create a safety system technology to be applied to the home kitchen, namely the design of an early detection system for fires based on the Internet Of Things (IoT) using ESP8266 which is useful for monitoring kitchen conditions and will automatically send a notification of the kitchen condition if the sensor reads an incident. The Hardware Design uses several tools consisting of ESP8266, Arduino R3. Jumper Cables, Fire Sensors, MQ-2 Gas Sensors, Mini Fans, Mini Water Pumps, Relays, Buzzers. and for the software design using Arduino IDE for system programming and Blynk as an application to display notifications. The designed system will be tested using black box testing which is used to determine whether the designed system will meet the specified parameters or not, and the results of the design state that the system is in accordance with the parameters used.
