Abstract

Penelitian ini bertujuan untuk menganalisis gaya yang bekerja pada bagian silider pada perancangan alat angkut dengan tipe scissor lift yang saat ini banyak digunakan di dunia industri. Alat yang dirancang mampu mengangkat beban 1000 kg berdasarkan perhitungan menggunakan standar ANSI MH29.1-2012. Selain dirancang secara perhitungan manual, simulasi model juga digunakan untuk mengkonfirmasi hasil perhitungan secara manual. Berdasarkan hasil perhitungan diperoleh gaya silider pada posisi terendah sebesar 23.641,74 N. Selain itu, beban gaya silider pada posisi tertinggi sebesar 74.473,03 N. Berdasarkan hasil perhitungan tegangan manual yang didapat dapat disimpulkan bahwa tegangan yang dihitung tidak melebihi tegangan normal yang diijinkan sehingga desain scissor lift kapasitas 1.000 kg berdasarkan standar ANSI MH29.1-2012 dinyatakan bisa dibuat untuk difabrikasi.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh komposisi media arang aktif, putaran katup, dan volume media terhadap ketebalan endapan kotoran. Penelitian ini menggunakan desain eksperimental. Media saring yang dipergunakan adalah dan arang aktif. Eksperimen dilakukan untuk mendapatkan kualitas air yang baik dengan veriabel yang dipilih adalah perbandingan komposisi media saring yaitu arang aktif ( R (%) ),bukaan katup ( Q(putaran)) dan volume media ( V (m) ). Ketiga parameter tersebut merupakan variabel tidak bebas yang akan diuji pengaruhnya terhadap kualitas air hasil proses penyaringan. Dari hasil pengujian tersebut akan didapatkan variabel mana saja yang paling berpengaruh terhadap kualitas air hasil penyaringan. Untuk menentukan kualitas air hasil penyaringan yaitu dengan cara mencampurkan serbuk PAC yang sudah dicairkan sebanyak satu sendok teh untuk satu liter air hasil penyaringan, dan didiamkan selama 15 menit sehingga kotoran terikat oleh PAC dan mengapung di permukaan air, kemudian diukur ketebalannya. Semakin tipis kotoran yang mengapung berarti kualitas air semakin baik. Hasil eksperimen menunjukkan variable yang paling berpengaruh adalah Rasio media saring dengan ketebalan kotoran 0,025 cm dan debit dengan ketebalan kotoran 0,625 cm. Berdasarkan hasil perhitungan percobaan menggunakan metode Least Square diperoleh persamaan Y = -0,9573 Q + 5,4504 R. Persamaan ini berlaku untuk kondisi Q dari ½ putaran sampai 1 putaran dan R dari 50% sampai 60% arang aktif. Dari pengujian dan perhitungan dari analisa kualitas air hasil penyaringan dengan media dan arang aktif dengan komposisi perbandingan dan arang aktif 0,5 % dan 0,6% dan debitnya 0,5 putaran dan 1 putaran kran dan Volume 1,5 kg dan 3 kg diperoleh kesimpulan bahwa yang sangat berpengaruh adalah Debit dan rasio media saring, saringan berpengaruh terhadap kualitas dan kejernihan air, semakin banyak media, maka kualitas penyaringan semakin baik, variasi komposisi media berpengaruh terhadap kualitas air hasil penyaringan.

Abstract

This study aims to determine the effect of adding EP and ER additives on the efficiency of motor vehicles. The indicator used as fuel efficiency is the Specific Fuel Consumption (SFC). The fuel used is RON 90, RON 92, RON 95 on a 4 stroke engine type. Each fuel is then added with EP and ER additives and is run on a 4 stroke engine. After being tested, the torque, revolutions per minute (rpm), and SFC were calculated. The results showed that the lowest SFC value for the addition of ER additives at RON 92 was 0.093.

Abstract

This study aims to develop a dynamic system model that describes the relationship ofwater, socio-economic, and water resources (lake size) sub-systems in Situ Binong. In addition,this study also aims to make predictions of water resources conditions (lake size) Situ Binong forthe next 5 years. The model is prepared using a dynamic system approach. The Situ Binong waterflow model is available water resources consisting of 3 sub-systems namely natural water flowsub-systems, socio-economic, and water resources Situ Binong. The result of the research showsthat the requirement of Situ Binong water resources every year is increasing so that the volume ofSitu Binong is decreasing. In addition, the volume of water resources Situ Binong influenced bysupply and demand. Supply comes from domestic waste and natural water flow such asprecipitation, infiltration and surface flow. While demand comes from WTP intake, irrigation, andevaporation.

Abstract

This study shows how to model the best results of several bicycle frame designs with a variety of materials. The use of various materials to change the design of a bicycle frame is the main topic of this research. Materials such as aluminum, titanium and carbon steel have specific features that can affect the strength, weight and response of a bicycle frame. This research involves designing a bicycle frame design using SolidWorks 2022, which is then used for simulation and strength analysis with Ansys. In this experiment, various materials were used, including aluminum alloy, titanium and carbon steel to measure the stress and deformation of each design and material tested. The purpose of this research is to study how the use of different types of materials when changing the design of a bicycle frame impacts the performance and strength of the bicycle. Tests were conducted through ansys simulation, with dynamic loads under conditions of daily bicycle use. The best data obtained in design 1 on titanium material, the top-tube section experienced a stress of 18.156 MPa and a deformation of 0.012078 mm. For aluminum material, the head-tube section experienced the lowest stress of 1.211 MPa and deformation of 0.0034886 mm. These results provide important insights for developing more efficient bicycle frame designs that can be tailored to user requirements and also impact the development of new materials in the bicycle industry aimed at improving the performance and durability of bicycle frames.

Abstract

Gas Tungsten Arc Welding (GTAW) or Tungsten Inert Gas (TIG) Welding employs a tungsten electrode and argon shielding gas to protect the molten metal from atmospheric contamination, resulting in strong and permanent joints. SS400 steel, widely used due to its favorable mechanical properties, can be welded using this method. However, weld quality is strongly influenced by variations in welding current. Too low a current leads to shallow penetration, while excessive current may cause defects and microstructural damage. This study aims to analyze the effect of GTAW current variation on the tensile strength, hardness, and microstructure of SS400 steel with different thicknesses (1.2 mm, 5 mm, and 6 mm). A total of 27 specimens were tested using an experimental method. Tensile strength was evaluated with a universal testing machine, hardness was measured using the Rockwell test, and microstructure was analyzed through metallography. The results show that hardness and tensile strength values are affected by the combination of welding current and plate thickness. Lower current increases hardness, while higher current reduces it. Yield strength and tensile strength decrease with increasing current and thickness due to higher heat input, while elongation varies depending on plate conditions. The microstructure reveals that martensite forms only in medium-thickness plates (5 mm), whereas thin and thick plates are dominated by ferrite and pearlite with grain growth at higher currents.
