Abstract

Medical treatment of patients during the Covid-19 pandemic is a problem for medical staff related to the high risk of transmission. Medical staff (NAKES) need to be equipped with hight protective equipment to ensure they are not directly exposed from the patients whose status is unclear, whether infected or not. The most important equipment is protective equipment at the time of intubation that is useful to protect the doctor from sprinkling the patient's saliva. This study aims to redesign the intubation trachel instrument by the Department of Anesthesiology Uttaradit Hospital, Thailand by considering aspects of ergonomics and material limitations in Indonesia, especially in the city of Padang. The study was conducted using anthropometric data of Agro Industrial Engineering students. The results of this study are finding a trachel intubation tool that is simpler and more ergonomic without reducing its function as a personal protective device.

Abstract

Peramalan merupakan tahapan awal dalam kegiatan perencanaan produksi  yang fungsinya adalah sebagai dasar dalam merencanakan kegiatan produksi selanjutnya. Kehandalan sebuah metode peramalan ditentukan dengan menghitung nilai simpangan (error) hasil peramalan dengan nilai sebenarnya. Metode ARIMA (Autoregressive Integrated Moving Average) merupakan salah satu metode peramalan jangka menengah yang  menghasilkan  nilai  ramalan  yang  cukup  baik  dibandingkan  dengan  metode lainnya. Penelitian ini bertujuan untuk membuktikan asumsi di atas dan juga untuk menentukan nilai peramalan periode selanjutnya dengan objek yang dijadikan sebagai studi kasus adalah PT MK yang memproduksi teh hijau. Data yang digunakan adalah data periode Januari 2012 sampai dengan Desember 2016, dengan software Minitab sebagai alat bantu perhitungan. Hasil penelitian menunjukkan bahwasanya model yang tepat dalam meramalkan penjualan di PT MK adalah model ARIMA (2,2,4). Perbandingan nilai error model ARIMA (2,2,4) dilakukan dengan metode peramalan lainnya yaitu Metode Trend Linier dan Kuadratis.   Hasil perbandingan   juga menunjukkan bahwasanya metode ARIMA masih yang terbaik. Hasil peramalan juga menghasilkan nilai peramalan untuk periode satu tahun berikutnya.

Abstract

CV. XYZ is a company engaged in food processing, it processes meat as the main raw material. Beef rollade is one of the products produced by CV. XYZ using "Fort Quarter" (FQ) beef as raw materials and auxiliary ingredients, i.e spices, eggs, onions, TVP (Texture Vegetable Protein) Red, and flour. TVP Red is an important auxiliary raw material in beef rollade production. A shortage of auxiliary materials for TVP Red during the production process will disrupt the process and if production continues, the product quality will decrease. Currently, the inventory policy carried out by CV. XYZ is to check the inventory of and auxiliary materials just before carrying out production activities so that if there is a shortage of auxiliary materials, new orders are made at that time. Therefore, the aim of this study is to determine the number of orders and the optimal frequency of ordering TVP Red using the EOQ method and determining the total cost of TVP Red inventory before and after using the EOQ method. Based on the results of calculations carried out using the EOQ, it can be concluded that the number of economical purchases of TVP Red is 1,007.6 Kg per order. With that number of purchases, the frequency of ordering by CV. XYZ is reduced to 13 times in one year. The difference in the frequency of these purchases is 25 times in one year. With purchase frequency of 13 times in one year, it can save the total inventory cost of Rp. 163.972,4.

Abstract

The issue of renewable energy sources has become a concern, especially after energy sources using fossil fuels are running low. One form of renewable energy that has not been managed optimally is a source of energy that comes from livestock waste from livestock. This livestock waste contains potential that is beneficial to the community. LIvestock waste in the form of cow dung is processed into biogas and can be used as a source of fuel for the community. Dairy farming in Nagari Lasi, Canduang District, Agam Regency, West Sumatra Province, has had a very positive influence on the community, including in the economic aspect. Since then, individuals or communities have started to open businesses, both similar businesses and businesses related to livestock activities. Currently the number of cattle in Nagari Lasi has reached around 1000 heads, plus other livestock such as buffalo and goats. The number of livestock so that the source of cow dung waste is also widely available to be processed as a renewable energy source. One of the tri dharma of higher education for lecturers is to carry out community service. For this reason, the lecturer of the Department of Agro-Industrial Engineering at the ATI Polytechnic Padang carries out service in a dairy farm in Nagari Lasi, Canduang District, Agam Regency, West Sumatra Province. For the initial stage, a digester is built which is a device that becomes a place where organic matter (cow dung) is broken down by bacteria anaerobically (without air) into CH4 and CO2 gases. This CH4 gas is called biogas which can be used as fuel. In addition to producing biogas, the leftover sludge from the dried process will become compost. This compost can also be used by the community for agriculture. The fermentation process that occurs in the digester has produced biogas and can be used as fuel. For 50 liters of cow dung, after being fermented it produces biogas which can fully fill a 500 liter capacity package in three hours. And that amount of gas can be used for burning in the stove for two hours continuously. Combustion using the biogas produced is able to boil water with a capacity of three liters in about ten minutes.

Abstract

The more sophisticated of the electronic equipment, so the for us to provide information to the public, in this case to provide any information including information about alcohol content in drinks to the public fast dan directly, we can use the internet and a website which can provide information in the form of text,picture, audio or video. In this research we will use the MQ-3 alcohol sensor, the camera and Raspberry pi which the whole system is a live stream means that no data is edited, any data readable by sensor then the data that is directly uploaded to the webserver. The method in this design is used two Raspberry pi3 which one function as client and the other as server, on client side paired a Raspberry camera (picamera), data acquisition AD / DA, and MQ-3 sensor while on server side there apache, mysql with client-server communication system and using python programming language and socket programing. The results of the design show that the MQ-3 and picamera sensors are running well and data can be sent from client to server.

Abstract

Industri pengolahan crumb rubber di Sumatera Barat memiliki operator trolley sebagai bagian dari pekerjanya. Saat ini, analisis lama waktu istirahat berdasarkan beban kerja operator trolley belum pernah dilakukan oleh perusahaan. Berdasarkan hasil observasi yang dilakukan secara langsung menggunakan kuesioner Nordic Body Map (NBM), lebih dari 50% operator trolley yang bekerja mengalami keluhan pada bagian kaki. Sehingga dilakukan analisis lama waktu istirahat berdasarkan beban kerja operator trolley dengan pendekatan fisiologis pada crumb rubber industry di Sumatera Barat. Penentuan waktu istirahat berdasarkan beban kerja menggunakan metode tidak langsung dengan menghitung denyut nadi selama bekerja serta metode langsung dilihat melalui asupan oksigen selama bekerja. Berdasarkan hasil pengukuran beban kerja, menggunakan metode pengukuran tidak langsung, didapatkan %CVL pada pekerja proses pembongkaran trolley meningkat mencapai 58,81% sehingga diperlukan perbaikan. Pada rata-rata P1, P2, P3 pekerja pembongkaran trolley adalah 88,6 atau mempunyai nadi pemulihan normal dan beban kerja tidak berlebihan (not excessuve). Untuk hal tersebut perlu dilakukan pengkajian lebih lanjut. Pada pengukuran menggunakan metode pengukuran langsung, total metabolisme yang didapat sebesar 206,86 Kkal/jam dengan beban kerja tergolong sedang. Berdasarkan pendekatan fisiologis untuk penentuan waktu istirahat menyatakan bahwa tidak dibutuhkan waktu istirahat tambahan selama melakukan kerja pada proses pembongkaran trolley tersebut (Rt = 0).
