Sundanese Ethnomathematics: Mathematical Activities in Estimating, Measuring, and Making Patterns

Mathematics is a form of culture integrated in all aspects of society, wherever there are, including the sundanese ethnic communities. This enables the mathematical concepts embedded in cultural practices and recognizes that all people develop a special way of doing mathematics called ethnomathematics activities. Sundanese ethnomathematics is mathematics in sundanese culture implemented in community activities. Sundanese ethnic sundanese people living in the area of West Java Indonesia, speaking sundanese language, and having activities reflecting sundanese culture. Sundanese ethnomathematics in this study has three activities, namely estimating, measuring, and making patterns appearing in the activities in term of kibik (a unit for measuring volume), bata (a unit for measuring surface area), and path pihuntuan (a model of cane work).DOI: http://dx.doi.org/10.22342/jme.8.2.4055.185-19

Production of Methyl Laurate From Coconut Cream Through Fractionation of Methyl Ester

This paper concerns the production of methyl laurate from coconut cream through fractionation of methyl esters. Coconut oil was produced by wet processing of coconut cream. The esters were prepared by reacting coconut oil and methanol using homogeneous catalyst KOH in a batch reactor, followed by fractionation of fatty acid methyl esters (FAME) at various reduced pressures applying differential batch vacuum distillation. Experimental data were compared with simulation of a batch distillation employing the simple Raoult's model and modified Raoult's model of phase equilibria. Activity coefficients (γi) were determined by optimization to refine the models. The modified Rault's model with activity coefficients gave better agreement with the experimental data, giving the value of γi between 0,56-0,73. For a given boiling temperature, lower operating pressure produced higher purity of C10 and C12 FAME for respective distillates

PENERAPAN MODEL COOPERATIVE LEARNING TIPE NUMBERED HEADS TOGETHER (NHT) UNTUK MENINGKATKAN MOTIVASI DAN HASIL BELAJAR SISWA KELAS IV PADA MATA PELAJARAN IPS DI SDN TEGALGEDE 02 JEMBER

Abstract. The social studies is designed to develop student's knowledge, comprehension and ability in analyzing social condition of the society in order to establish the dynamic of social life. Cooperative learning model type NHT is the type of learning which combines the talkactive method with the discussion. This type has a special feature in which it has the numbering system so that the domination of certain student cannot be happaned and all the students will be ready from the start. The purpose of this research is to improve motivation and student learning outcomes through the aplication of cooperative learning model type NHT in grade IV of social studies in SDN Tegalgede 02 Jember in the even of  second Semester Academic Year 2015/2016. This type of research is Classroom Action Research, which is conducted for 2 cycles, the first cycle consists of two meetings and one time test at the end of the cycle, the second meeting consisted of two meeting and one test at the end of the cycle. The research subjects were students of class IV SDN Tegalgede 02 Jember with the total of 30 students, consisting of 17 males and 13 females. The data collection is done with interviews, observations, questionnaires, documentation, and testing. Based on the research results show that through the application of cooperative learning model type NHT the results showed that the average score of student's motivation increased from pre-cycle of 52 to the first cycle 68 and increased again to 77 in the second cycle. Scores of student learning outcomes in the classical style from a pre-cycle 62 to 69 in the first cycle, and increased again to 76 in the second cycle. Keywords: cooperative learning model type NHT, learning motivation, learning outcomes 

Analisis Kinerja Bundaran di Bundaran Nganjuk untuk Perencanaan Jalan Tol Kertosono – Kediri

AbstractThe Adipura Nganjuk Roundabout is a pathway that often gets stuck due to being crossed by a railroad crossing. The location is close to Nganjuk Regency, Kediri Regency and Jombang Regency which are distribution points for the western and southern regions in East Java Province. Need to do a management in traffic engineering which includes the construction of toll roads from Nganjuk to Kediri, this roundabout does not get saturated. The purpose of this study is as a benchmark Traffic forecast forecasting is carried out for 6 years from 2019 to 2025. The research method uses a roundabout analysis using a manual Indonesian road capacity. Based on the results of forecasting calculations, the Adipura Nganjuk roundabout will be able to reduce the value of the degree of saturation by building the Kertosono-Kediri toll road to a DS value below 1 (one). In 2019 the DS is 0.77. While in 2021 DS decreased to 0.44 through the construction of the Kertosono-Kediri toll road. In 2025 DS increased again to 0.59, in 2030 DS = 0.84, and in 2035 again increased to 1.19 as vehicle growth. The solution is to count the number of vehicles and work on further traffic.Keywords: Traffic Performance, Degree of Saturation, Roundabout Intersection, Toll PlanningAbstrakBundaran Adipura Nganjuk adalah jalur yang sering terjadi macet karena berdekatan dengan perlintasan kereta api. Lokasinya berada dekat Kabupaten Nganjuk, Kabupaten Kediri dan Kabupaten Jombang adalah tempat distribusi perekonomian untuk wilayah barat dan selatan di Provinsi jawa Timur. Perlu dilakukan suatu manajemen dalam rekayasa lalu lintas berupa pembangunan jalan tol dari Nganjuk ke Kediri supaya bundaran tersebut tidak semakin jenuh. Tujuan penelitian ini adalah sebagai tolok ukur Peramalan kinerja lalu lintas dilakukan selama 6 tahun dari tahun 2019 hingga tahun 2025. Metode penelitian menggunakan analisis simpang bundaran menggunakan manual kapasitas jalan Indonesia. Berdasarkan hasil perhitungan peramalan, bundaran Adipura Nganjuk akan dapat menurunkan nilai derajat kejenuhan dengan membangun jalan tol Kertosono-Kediri menjadi nilai DS dibawah 1 (satu). Tahun 2019 DS adalah 0,77. Sedangkan tahun 2021 DS menurun menjadi 0,44 seiring pembangunan tol Kertosono-Kediri. Tahun 2025 DS meningkat kembali menjadi 0,59, Tahun 2030 DS = 0,84, dan Tahun 2035 kembali meningkat menjadi 1,19 seiring pertumbuhan kendaraan. Solusinya adalah membatasi jumlah kendaraan dan melakukan rekayasa lalulintas lebih lanjut.Kata Kunci: Kinerja lalu-lintas, Derajat Kejenuhan, Simpang Bundaran, Perencanaan To

Bioactive Compounds of Rambutan (Nephelium lappaceum L.)

Rambutan, a widely popular tropical fruit encompasses rich amount of bioactive compounds. All parts of this plant (leaves, bark, root, fruits, fruit skin, pulp and seeds) finds traditional usage, and are linked with high therapeutic values. Rambutan fruits parts like that of peel, pulp and seeds have been scientifically investigated in-depth and is reported to encompass high amounts of bioactive compounds (such as polyphenol, flavonoid, alkaloid, essential mineral, dietary fiber). These compounds contribute towards antioxidant, antimicrobial, anticancer, antidiabetic and anti-obesity activities. However, literature pertaining towards potential industrial applications (food, cosmetics, pharmaceutical) of rambutan fruits are limited. In the present chapter, it is intended to document some of the interesting research themes published on rambutan fruits, and identify the existing gaps to open up arena for future research work.This chapter theme is based on our ongoing project—VALORTECH, which has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 810630
