Abstract

Proses pencampuran biodiesel dengan bahan bakar diesel telah lama dilaksanakan dimana pemerintah Indonesia telah mengalokasikan kadar biodiesel sebesar 7,5 % di dalam bahan bakar diesel. Oleh karena itu, perlu dilakukan pembuatan bahan bakar emulsi minyak diesel dan air yang dapat memperbaiki efisiensi pembakaran, mengurangi emisi gas buang dan menghemat konsumsi bahan bakar diesel murni. Pembentukan bahan bakar emulsi dari campuran minyak diesel dan air diharapkan dapat mengurangi emisi gas nitrogen oksida (NOx) dan karbonmonoksida. Dalam penelitian ini, akan dilakukan proses emulsi bahan bakar diesel dan air dengan adanya penambahan surfaktan Span 85 dan Tween 80. Ada beberapa aspek yang akan mempengaruhi proses pembentukan emulsi satu fasa antara minyak diesel, dan air. Beberapa aspek yang mempengaruhi antara lain pengaruh variasi penambahan volume minyak diesel, volume air dan volume surfaktan terhadap stabilitas emulsi yang terbentuk. Penelitian ini telah menghasilkan 3 bentuk emulsi satu fasa antara minyak diesel, surfaktan dan air.

Abstract

This research develops an analysis structure program for plane truss structure using stiffness matrix method and based on graphical user interface. The program is developed using GUIDE feature from MATLAB R2014 software. The features that were developed of this program is to analyze the reaction forces, internal forces and global displacement for plane truss structure. There are 3 (three) types of plane structures were considered. Reaction forces, internal forces and global displacement which obtained from the program were compared to commercial program which is ETABS 2016. Based on the result, there is not significantly different between the program which developed and ETABS 2016 for reaction forces, internal forces or global displacement. Therefore, the program can be an alternative software to analyze plane truss structure

Abstract

GeoGebra merupakan media pembelajaran matematika untuk mendemonstrasikan atau memvisualisasikan konsep-konsep matematis serta sebagai alat bantu untuk mengkonstruksi konsep- konsep matematis seperti aplikasi pada fungsi permintaan, penawaran dan model keseimbangan pasar. Keseimbangan pasar yang dimaksud adalah pertemuan antara penjual (produsen) dan pembeli (konsumen) baik secara langsung maupun tidak langsung. Pasar dikatakan seimbang (market equilibrium) apabila: Jumlah barang yang diminta di pasar tersebut sama dengan jumlah barang yang ditawarkan. Harga barang yang ditawarkan oleh penjual (produsen) sama dengan harga yang diminta oleh pembeli (konsumen).

Abstract

The campus has an organization to develop the potential of its students according to the student division therefore This study aims to create a web-based service information system for student organizations in order to facilitate the service and implementation of procedures for submitting proposals and activity reports. The data were obtained through observations, Correspondence documents, direct interviews with the campus and organizational management. This system is built using visual studio code and mysql as a database storage service. The system development method in this research uses the waterfall method with the stages, namely analysis, design, coding, testing and implementation (maintenance programs). The results of this study indicate that the student organization service information system can run well. Based on the results of testing using blackbox testing techniques obtained 81% results from respondents, so it is said to be suitable for use based on the tests carried out.

Abstract

The workshop is one of the business facilities that provides after-sales repair services to consumers. Punctuality is very important for repair service users. The reservation process for booking and reminder services carried out at the Benelli Showroom is still using the telephone system or coming directly to the workshop. This study aims to design an information system for booking reservations and service reminders that are effective, efficient, and easy to use by Service Advisors and Customers. In this study, qualitative data analysis methods were used. Qualitative data analysis is a research procedure that produces descriptive data in the form of written or spoken words from people and observable behavior. The method that can be used in system analysis is the PIECES method (performance, information, economy, control, efficiency, control, and service). . The design method of this system uses UML (Unifield Modeling Language), namely using use case diagrams, Class diagrams and Activity diagrams. The results of the design of the reservation information system for booking and motorbike service reminders can provide convenience and customer satisfaction in booking service, and simplify the work of service advisors.

Abstract

The weight and height measurement tools used at the Tarowang Jeneponto Health Center do not get accurate data, because they are still conventional or manual. this has an impact on inefficient use because it is still carried out by humans who have inaccuracies and usually human error occurs. This study aims to design an accurate and automatic body weight and height measurement system at the Tarowang Jeneponto Public Health Center. This data was obtained through field research, library research, interviews and documentation. The method used in this research is the blackbox method and UAT (User Acceptance Test). The results of this study indicate that the System for Measuring Weight and Height with Internet Of Things-Based Automatic Recording was successfully implemented and very well used with a questionnaire value of 86.4%.

Abstract

Tetraselmi chuii merupakan mikroalga dari golongan alga hijau (Chlorophyceae) mempunyai nilai gizi tinggi, pemanfaatan nutraceutical alga secara komersial telah banyak diterapkan, antara lain sebagai bahan makanan, energi biomassa, pupuk pertanian, dan dalam industri farmasi. Penelitian ini bertujuan mengetahui komposisi asam lemak hasil ekstrak Tetraselmi chuii dengan menggunakan pelarut minyak zaitun. Metode yang digunakan dalam penelitian ini adalah mengekstrak asam lemak Tetraselmi chuii menggunakan minyak zaitun dengan perbandingan konsetrasi (gram mikroalga : mL minyak zaitun) yaitu, 1:10 b/v, 1:15 b/v 1:20 b/v, dan 1:25 b/v. Asam lemak hasil ekstraksi dianalisis dengan GC-MS. Hasil penelitian diperoleh kadar optimum asam lemak pada perbandingan konsentrasi (gram mikroalga : mL minyak zaitun) 1:20 b/v yaitu, 50,0733 %b/v. Perbandingan konsentrasi minyak zaitun dapat meningkatkan ekstraksi asam lemak Tetraselmi chuii. Komposisi asam lemak asam lemak optimum ekstrak Tetraselmi chuii berdasarkan hasil GC-MS yaitu, 1,86% asam palmitoleat, 20,50% asam palmitat, 13,29% asam linoleat, 61,08% asam oleat, dan 4,57% asam stearat

Abstract

A dc motor is a machine that converts dc electrical energy into mechanical energy. One way to assess the work of a dc motor is to know the amount of current and speed in the initial conditions before adjustments/changes are made. Current and speed settings can be made by adjusting the motor armature voltage at starting. The greater the time the armature voltage reaches its nominal value, the armature current will be smaller so that it is safe for the motorbike and vice versa.

Abstract

Cahaya Anugrah Sentosa Makassar produces peanut egg snacks. In the production process of this egg peanut snack has a fairly high risk because the work process is carried out continuously. This process still uses human power without the use of work aids. Besides that, the process of packing egg nuts snacks isdone on the floor in a sitting position. This is very dangerous for the work force because it has a risk of occupational diseases, fatigue at work, so that workers become uncomfortable at work. The purpose ofthis study is to design ergonomic work methods in the packing section to reduce the risk of occupational diseases and will increase work productivity. The method used in this research is subjectivity analisysis and anthropometric analisis. From the subjectivity analysis it can be seen the level of operator complaints, while antropometric analysis obtained the operator’s body size which can be adjusted to design work aids. From the results of the oprator subjectivity analysis, it can be seen that the comparison of the level of complaints before and after the design of work methods. Prior to the design of the work methods, the average complaint scale has not felt pain and is not tired for along time
