Various methods can be used to construct a mathematical model of the transportation problems. One model that can be used is a linear model. Several studies have used a linear model to get the schedule and the optimal route of bus trips. This research will build a mathematical model of a city bus transportation problems in DIY using linear models. Linear model is built to get the condition density city bus passengers on shifts respectively that morning, noon, and evening. After finding a suitable model, applied to the bus passengers data in Yogyakarta. From these results it can be seen the optimum conditions in terms of density, because the condition of the city bus at this time that quiet enthusiasts. Besides, the optimum density at each shift in the morning is 11 passengers, 10 passengers during the day, and evening 9 passengers. Keywords: transportation problems, the linear model, the optimal route, density

Kelebihan dari turbin angin poros horizontal yaitu efisiensinya lebih tinggi dibanding turbin angin poros vertikal karena sudu selalu bergerak lurus terhadap arah angin dan menerima daya sepanjang putaran. Tujuan dari tugas akhir ini dibuat untuk mengembangkan tugas akhir tahun 2018 dengan memvariasikan jumlah sudu yaitu 9, 12, dan 15 dan membandingkan kinerja turbin angin dengan menggunakan variasi kecepatan angin. Metode yang digunakan yaitu dengan melakukan tahap penelitian berupa merancang, membuat, dan merakit turbin angin. Turbin angin memiliki dimensi panjang sudu sebesar 650 mm, lebar sisi masuk 60 mm, dan lebar sisi keluar 80 mm. Sedangkan hub memiliki diameter 68,8 mm dan tinggi kerangka 1,5 m. Variabel penelitian meliputi variasi jumlah sudu yaitu 9 buah, 12 buah, dan 15 buah. Data dari hasil pengujian ini kemudian dibuat tabel dan dibandingkan dengan menganalisa grafik karakteristik putaran dan efisiensi. Tahap akhir dari pengujian ini yaitu untuk mendapatkan efisiensi sistem terbaik dengan variabel yang digunakan. Nilai efisiensi pada sudu 9 yaitu sebesar 1,41% pada kecepatan angin 5,15 m/s, pada sudu 12 yaitu sebesar 2,59% pada kecepatan angin 5,58 m/s, dan pada sudu 15 yaitu sebesar 2,68% pada kecepatan angin 5,7 m/s

This research is a study that aims to determine the differences in emotional intelligence and student learning outcomes which are viewed from the student entrance path, namely the SNMPTN, SBMPTN and Mandiri pathways. To reach the target of the study, 2 instruments were used, namely 1) an instrument to measure emotional intelligence in the form of a questionnaire, 2) an instrument for measuring student calculus learning outcomes. The population in this study were students majoring in Chemistry FMIPA UNM Makassar 2018/2019 academic year. While the samples in the study were students majoring in chemistry who programed the calculus courses of class A and B of Chemical Education Study Program. The data analysis technique used is inferential statistical analysis using ANOVA test. The results of this study obtained F-count = 1.94 <FTabel = 3.129 for the learning outcomes test and F-count = 0.26 <FTabel = 3.129 for emotional intelligence. This means that the variables of emotional intelligence and student calculus learning outcomes are not significantly different from students who enter through the SNMPTN, SBMPTN and Mandiri pathways.

The purposes of this research were to know the effectiveness of mathematics learning with scientificapproach through the cooperative model of type numbered heads together (NHT) in terms of student achievement,the effectiveness of mathematics learning with scientific approach in terms of student achievement, and to knowwhich one was more effective between mathematics learning with scientific approach through the cooperativemodel of type NHT and with scientific approach without NHT in terms of student achievement. This research usedquasi-experimental with pre-test and post-test control group design. Its population was all students of grade X SMANegeri 1 Kalasan. The samples were class X MIA 2 as experiment class which given scientific approach throughthe cooperative model of type NHT and class X MIA 1 as control class which given scientific approach. Theinstruments used in this research were learning instrument, i.e. lesson plan and student worksheet, pre-test and posttest as test instrument to measure student achievement, and observation sheets as non-test instrument. Thehypotheses testing used were one sample t-test and independent sample t-test. The results indicated thatmathematics learning with scientific approach through the cooperative model of type NHT was effective in termsof student achievement. Mathematics learning with scientific approach was also effective in terms of studentachievement. But, the post-test result means between the two classes were not significantly different. So, themathematics learning with scientific approach through the cooperative model of type NHT was not more effectivethan mathematics learning with scientific approach without NHT in terms of student achievement.

The home industry partner for the tofu business is located in Kalidoh Langensari Barat Village, Ungaran Barat District, Semarang Regency. The partner's obstacle is the failure to meet the increasing market demand. This obstacle is caused because the production process is still carried out manually or traditionally so that tofu production is limited to human power. The right solution offered through this community service is the application of process technology in the form of a soybean grinding machine with a rotary system to increase tofu productivity. The purpose of this community service is to make an electric soybean grinding machine, apply a rotary grinding machine to the tofu production process, and conduct evaluation and assistance to maintain the sustainability of the program. The initial stage carried out in this service consists of planning and making the machine. Planning is based on market needs and partner conditions related to the provision of electrical energy. The design results are made through machine work in the Mechanical Department workshop. The next stage is the application of the machine including assembly and installation of the machine at the partner's location, as well as operational training and machine maintenance. The final stage of the service is evaluation and assistance. Evaluation is carried out by directly assessing the partner's operational practices on the machine that has been assisted. The assistance provided includes supervision, work control, and direction when the partner produces tofu using the production machine. It is expected that the rotary soybean grinding machine can increase the production of partner tofu.
