Abstract

Indonesia has been know as own high diversity of flora and fauna. In addition, Indonesia has been know high diversity of ethnics which has various distinctive traditions, including local knowledge. One of the local knowledge on using of traditional medicinal plants. The utilization of plants as medicinal plants has never been reported yet because of the changes of era, the local wisdom knowledge especially for medicinal plants has faded away. The purpose of this research is to determine the local knowledge of Jerieng ethnic in utilizing the plant include the parts of the plant, the processing, and the benefit as medicinal plants), collecting data of the medicinal plants diversity (species numbers, scientific name, local name, familes, habitat and habitus). The method of this research was used the qualitative and descriptive analysis. Data was collected from survey and interview in the Jerieng ethnic using snowball sampling. The result of research show there are 82 plants species 52 families, 16 informans, and 45 species disease. The most dominant families of medicinal plants is Zingiberaceae with 7 kinds and graminae//poaceae with 6 kinds. The most frequent used part of the plants by Jerieng ethnic are the leaf 46%, trunk habitus species 35% and the higher habitat is at plants garden house 52%.

Abstract

Every life needs a very important role especially the role in education. Improving the quality of education can be pursued by the use of appropriate learning models so as to improve students' reasoning abilities. The purpose of this study was to determine the differences in the influence of Novick's learning model and the learning model that is centered on educators on students' mathematical reasoning abilities, Knowing the interaction between learning models and SAVI learning styles (Somatic, Auditory, Visualization, Intelectually) on mathematical reasoning abilities learners. This research uses the Quasy Experiment Design method. The results obtained from this study are that learning by using Novick's learning model is more effective against mathematical reasoning for students, there is no interaction between Novick's learning model and SAVI learning style on mathematical reasoning abilities.

This study aims to(1) determinethe items quality of odd semesterfinal examin social class XII mathematics subject academic year 2014/2015 in terms of validity, reliability, level of difficulty, and distinguishing power, (2) createa program shape for calculating validity, reliability, level of difficulty and distinguishing power. The researchused quantitative descriptive method and documentation technique. The datas consisted of 128 students’ answer sheetsin social class XII academic year 2014/2015. The datas were analyzed by using several formulas of validity, reliability, level of difficulty, distinguishing powerand the use of IBM SPSS Statistics22 software and anates V4 software. The results showed that 22 questions (55%) were valid and 18 questions (45%) were invalid. The reliability of items was quite good where the reliability coefficient value > rtabel was 0.558 based on three formulas which were Anova Hoyt, Cronbach alpha and IBM SPSS Statistics 22. The difficulty level of items was not good because the items balances including easy, medium and difficult were not proportional, the proportional balance was 3-5-2 or 3-4-3. The distinguishing power of items showed that 1 item (2.50%) was very good, 9 items (22.50%) were good, 10 items (25%) were moderate, 14 items (35%) were less good and 6 items (15%) were bad. In addition to the above results, this study also resulted a program shape to facilitate the calculation of item analysis. The program calculations are the validity index analysis, reliability, level of difficulty and distinguishing power of test instrument.

Abstract

Daun stevia merupakan bahan pemanis alami dengan kelebihan tingkat kemanisan 300 kali dari gula tebu. Pembudidayaan stevia yang relatif mudah dan aman jika dikonsumsi menjadikan pemanis stevia sebagai alternatif dari pemanis sintesis yang bersifat karsinogenik. Stevia dapat tumbuh di dataran dengan ketinggian 500 ? 1000 meter di atas permukaan laut. Kondisi optimum untuk pertumbuhan tanaman ini yaitu pada suhu 14 ? 27 °C dan pH antara 6,5 ?7,5. Tanaman stevia dapat dipanen pada saat tanaman berumur 40 ? 60 hari yaitu menjelang stadium berbunga karena pada saat inilah kandungan steviosida maksimal.Ekstraksi daun stevia pada penelitian ini dilakukan dengan menggunakan metode ekstraksi padat cair secara batch dengan pengontakan dispersi menggunakan pelarut air, metanol,atau etanol. Ekstraktor yang digunakan berkapasitas 1 liter dilengkapi dengan motor pengaduk, impeller (paddle), waterbath, dan kondensor. Penelitian diawali dengan pretreatment daun stevia yang meliputi pencucian, pengeringan, pengecilan ukuran, dan penyeragaman ukuran daun. Pengeringan dilakukan selama 4 jam dengan temperature 70 °C sehingga menghasilkan kadar air daun sebesar ± 5,37%. Daun stevia kemudian diekstraksi dengan memvariasikan temperatur (45°C, 50 °C, dan 55 °C) serta jenis pelarut (metanol, etanol, dan air). Analisa yang dilakukan yaitu kadar air, kadar abu, kadar steviosida, HPLC, dan gugus fungsi ekstrak daun stevia (FTIR).Hasil penelitian menunjukkan pelarut etanol menghasilkan yield ekstrak paling tinggi. Semakin tinggi temperatur, maka semakin besar yield ekstrak yang diperoleh serta semakin tinggi kadar abu ekstrak. Air menghasilkan kadar steviosida dari ekstrak paling tinggi karena air merupakan pelarut paling polar dibandingkan dengan etanol maupun metanol.Kata kunci: gula, stevia, steviosida, ekstraksi

Abstract

This study aims to determine the effect of using Excel and SPSS on student learning outcomes in advanced statistics courses. This type of research is quantitative research with experimental research designs. The action taken is an effort to develop learning technology, namely the constructivism learning approach that is packaged in statistical learning through the use of Excel and SPSS. Based on the analysis of learning outcomes data from statistical learning without the help of programs, with the help of Excel and SPSS programs, there is no significant effect of using Excel and SPSS programs on student learning outcomes. There are several things that cause the use of Excel and SPSS programs do not affect student learning outcomes, namely (1) Inadequate infrastructure, (2) students 'basic statistical skills are still low and (3) students' interest in learning statistics is still low.

PT. Karya Niaga di Bandar Lampung adalah perusahaan perdagangan lampu philips, dihadapkan pada masalah persaingan dalam pemasarannya dengan usaha sejenisnya. Oleh karena itu harus mendapatkan perhatian dan diberikan informasi atau promosi mengenai perkembangan produk harga maupun mutu dan pelayanannya, sehingga diharapkan efektivitas kerja karyawan yang tinggi dalam penjualan menjadi stabil bahkan meningkat. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh promosi terhadap efektivitas kerja karyawan pada PT. Karya Niaga di  Bandar Lampung. Hipotesis yang diajukan dalam penelitian ini adalah: ?Ada Pengaruh Promosi Terhadap Efektivitas Kerja Karyawan Pada PT. Karya Niaga di Bandar Lampung?. Pengambilan sampel menggunakan teknik sampel deret waktu (n = 10). Metode penelitian yang digunakan analisis kualitatif dan kuantitatif digunakan adalah regresi linier sederhana. Hasil analisis diperoleh persamaan bahwa : Y = -50,51  + 22,37 X, berarti r = + 1 atau mendekati + 1, mengartikan bahwa, apabila anggaran promosi dinaikan atau dikurangi 1%, maka nilai efektivitas kerja karyawan akan bertambah atau berkurang sebesar 22,37 % sedangkan bila anggran promosi tetap, maka nilai efektivitas kerja karyawan akan berkurang sebesar Rp. 50.510.000,-. Sehingga terbukti ada pengaruh promosi yang positif terhadap efektivitas kerja karyawan pada PT. Karya Niaga di Bandar Lampung. Hasil pengujian menggunakan rumus t student, menunjukkan bahwa t hitung   19,85 > t tabel 2,828, berarti Ho ditolak dan Ha diterima. Dengan demikian hipotesis yang diajukan: ?ada pengaruh promosi terhadap efektivitas kerja karyawan  pada PT. Karya Niaga  di  Bandar Lampung?, diterima.
