Abstract

Parkir kendaraan khususnya sepeda motor saat ini membutuhkan lahan parkir yang luas. Seiring dengan meningkatnya jumlah sepeda motor setiap tahunnya lahan parkir menjadi semakin kurang dan sempit. Masalah lainnya dengan sistem parkir konvensional saat ini membuat parkir menjadi semrawut, ditambah tidak teraturnya pemilik kendaraan dalam memarkirkan kendaraannya dan menjamurnya juru parkir liar. Kebutuhan lahan parkir di perkotaan menjadi hal yang serius untuk ditangani seiring perkembangan kendaraan yang terus bertambah. Solusi dari permasalahan lahan parkir telah dicoba oleh Negara Maju dengan memanfaatkan parkir betingkat otomatis, yang dapat dekendalikan oleh  pengendara dengan mudah. Sistem parkir ini menggunakan sistem otomasi yang dikendalikan dengan komputer. Sistem parkir bertingkat otomatis yang dikembangkan saat ini disusun dengan vertikal keatas dan bisa dirancang untuk vertikal ke bawah tanah. Solusi parkir seperti ini menjadi alternatif untuk  menanggulangi lahan parkir yang mulai berkurang. Cara kerja sistem parkir otomatis menggunakan sistem pneumatik, sensor, kamera dan komponen mekanis untuk mengambil sepeda motor, memindahkannya ke seluruh slot parkir yang kosong. Luas area parkir 45 m2 tinggi bangunan 9 m, dengan daya tampung maksimum 20 sepeda motor. Tempat parkir ini dapat digunakan pada area perkantoran, pasar, mall, tempat rekreasi dan lokasi lainnya yang membutuhkan tempat parkir khususnya sepeda motor.

Abstract

Tujuan dilakukan penelitian ini adalah untuk mengetahui pengaruh proses pendinginan dengan metode double quenching terhadap nilai kekerasan plat baja karbon rendah hasil pack carburizing dengan variasi waktu tahanan dan media karburasi arang tempurung kelapa. Proses karburasi adalah proses pengerasan permukaan pada logam untuk mendapatkan sifat keras pada permukaan dan sifat ulet pada bagian tengah logam. Pada penelitian ini, proses pack carburizing dilakukan pada temperatur 9000 C dengan 3 variasi waktu tahanan yang berbeda yaitu 1,5 jam, 2 jam dan 2,5 jam, dimana satu waktu tahanan menggunakan 3 spesimen uji. Komposisi media karburasi menggunakan 100% serbuk arang tempurung kelapa. Proses quenching pertama menggunakan air kemudian spesimen uji dipanaskan kembali diluar kotak karburasi pada temperatur 8000 C selama 1 jam dengan oli sebagai media quenching kedua. Dari hasil pengujian kekerasan diperoleh nilai kekerasan rata-rata spesimen uji dengan watu tahanan 1,5 jam sebesar 92,5 HRB, waktu tahanan 2 jam sebesar 95,8 HRB dan waktu tahanan 2,5 jam sebesar 92,9 HRB. Sedangkan hasil pengujian struktur mikro pada permukaan spesimen uji sebelum pack carburizing terlihat fasa ferit dengan sedikit fasa perlit dan pada permukaan spesimen uji setelah pack carburizing terdapat fasa ferit ang semakin sedikit dengan fasa perlit yang semakin banyak.

Abstract

The use of waste used oil is increasing every year, the resulting waste will also increase. Waste used oil is included in B3 waste which needs special handling. In line with the development of cities and regions, the volume of used oil continues to increase in line with the increase in the number of motorized vehicles and motorized machines. Even in rural areas, you can find small workshops, one of which is used oil. . In other words, the distribution of used oil is very wide from big cities to rural areas throughout Indonesia. The process in this research is changing the waste used oil into liquid fuel with the constant heat treatment. It is aimed to know the best result in the temperature of 250°C, 300°C and 350°C with pyrolysis process. The increase of temperature has a big effect toward the result of the exchanging process. The best result is at the temperature of 350°C which the volume got from the tap A is 1 liter and from the tap B is 0.2 liter. Than the tap sample A was tested against the exiting fuel standards. Based on the result of the specification test on the process of changing waste used oil, it was found that there were many weaknesses like the high viscosity value and the high content of water in the resultant product. But for other physical properties had fulfilled the standard of the fuel.Keywords: Temperature, used oil, pyrolysis, liquid fuel.

Abstract

Batok Kelapa merupakan salah satu bahan yang dapat diproses dalam pembuatan asap cair. Proses produksi arang dari batok kelapa secara tradisional yaitu dengan metode drum klin berpotensi menimbulkan polusi udara. Mesin penyulingan asap cair berbasis mikrokontroller bertujuan untuk membantu para pembuat arang dalam meminimalisisr dampak kesehatan akibat polusi udara dari asap serta menambah pendapatan berupa produk asap cair. Hasil pengujian prototipe diharapkan dapat meningkatan hasil produksi asap cair yaitu membandingkan menggunakan media air dengan temperatur ± 29°C dan menggunakan  refrigerasi yangmana temperatur air diturunkan sampai 15°C dengan pengontrolan mikrokontoller-Arduino UNO. Berdasarkan hasil pengujian di Desa Tanjung Lago Kabupaten Banyuasin diperoleh produk berupa asap cair tanpa sistem refrijerasi sebanyak 203 ml dan penyulingan dengan menggunakan sistem refrijerasi sebanyak 375 ml asap cair.

Abstract

The industry is currently transitioning into the Industrial Revolution 4.0 era. Technology disruption is becoming more prevalent. The major goal of this industrial revolution is to maintain the flow of essentials and goods. Technology advancements demand equipment, such as CNC machines, that can be utilized to produce the required components. Using a CNC Router 3018 machine for this investigation. Data from previously generated Computer Aided Design (CAD) programming is used during the production of specimen objects. It is then imported into the Computer Aided Manufacturing (CAM) programming software in order to generate the NC Code and operate the machine in accordance with the intended form. This research was done to find out how the CNC Router 3018's motion deviation on the XYZ axis affected things. Acrylic resin with a 10 mm thickness is used in the substance. The results of the measurement data analysis were then put through a "One Ways" ANOVA. Motion axis, specifically: X axis: deviation 0.6%; Y axis: 0.4% deviation; Z axis: deviation 0.77%. The CNC Router 3018 is effective for tasks like cutting and engraving.

Abstract

With the rapid development of technology, the need for innovation is also increasing. One of the most popular technologies today is 3D printers. However, to produce quality 3D prints, a good frame structure is essential. The most important part in 3D printing is the frame structure. The most crucial part in the 3D printing process is the frame structure, namely Core XY. This is very crucial because the frame structure of the Core XY 3D printer has a big influence on the load it will accommodate in supporting the overall 3D printing process. The material used in this research is 6061 aluminum with extrusion profile 2020. This research focuses on analyzing the strength and balance of the structure, as well as the strength of the joints on the Core XY 3D printer due to static loading. To achieve this goal, researchers used the finite element analysis method using Ansys 2021 R1 software to obtain an optimal simulation. The tests used by researchers were carried out by determining the static free value that occurs in the Core XY 3D printer frame. The structural analysis results show the maximum deflection value δmax = 0.25635mm, maximum yield stress εymax = 42.169 MPa, and maximum yield strain σymax = 6.1417e-004mm/mm. Researchers can conclude that the Core XY 3D printer is feasible to use to be able to produce 3D object prints.

Abstract

The Production Machinery Workshop at the Sriwijaya State Polytechnic are producing a lot of aluminum scrap left over from turning, where this waste is still thrown away. This will cause pollution to the environment and will be detrimental to the Sriwijaya State Polytechnic workshop. Casting is one way to deal with aluminum scrap, scrap be melted and then reshaped into a practical material that can be reused. The use of sand as a printing medium in recycling scrolls is not recommended because it is less effective and efficient in terms of long-term use. After research has been carried out, the resulting aluminum shaving waste can be reused as practical material provided that the shavings must be separated from other waste such as iron and steel. In the optimization process, the best value is obtained at the spindle speed factor of 900 rpm (A1), then the feeding depth at 0.5 mm (B1), and the feeding speed at 0.08 mm/put.
