    English as the first foreign language in Indonesia is taught starting from the elementary school level up to university level. The general objective of teaching English in Indonesia, based on the school based curriculum (KTSP), is to develop students’ communicative competence of the four language skills or aspects of teaching and learning; reading, speaking, listening, and writing. Richard (1992: 189) states that the teaching of language skills (reading speaking, listening, and writing) are related to each other, when a lesson involves activities that relate listening and speaking, reading and writing, it means that listening activity is related to spoken or oral language, and reading is related to written language. The purpose of learning English language in Junior High School is to achieve the functional level. In this, the students can develop their competences in oral or written to resolve daily problems. They are conscious of the importance and essential of English in the global era. They can develop their comprehension about language and culture (Depdiknas, 2006: 278)

Data kepraktisan diperoleh dari keterlaksanaan RPP menggunakan lembar penilaian kegiatan guru dianalisis menggunakan kategori 1-4. Data keefektivan dari 1) aktivitas siswa, 2) hasil belajar, 3) sikap spiritual, 4) sikap sosial, dan 5) keterampilan berpikir kritis siswa. Data aktivitas siswa dikumpulkan menggunakan lembar pengamatan aktivitas siswa berdasarkan frekuensi aktivitas yang muncul setiap 5\u27 dinyatakan dengan %. Aktivitas siswa rendah jika < 10%. Hasil belajar menggunakan tes dan diberi skor 1 (benar) dan 0 (salah), dengan KKM ≥ 2,67. Data sikap (spiritual dan sosial) diperoleh menggunakan lembar pengamatan sikap menggunakan kategori 1-4. Data keterampilan berpikir kritis siswa diperoleh menggunakan rubric, dan dikategorikan dengan %. Hasil penelitian perangkat pembelajaran valid karena 1) silabus dinyatakan valid namun melalui perbaikan, dan 2) komponen RPP, bahan ajar, LKS, dan lembar penilaian juga valid. Praktis karena guru mitra mampu melaksanakan pembelajaran. Efektif berdasarkan 1) sebagian besar aktivitas siswa sudah baik namun mempersentasikan hasil percobaan dan menjawab dan menanggapi penyajian kelompok lain masih perlu perbaikan, 2) hasil belajar siswa telah melampaui ketuntasan minimal, 3) sikap spiritual sudah baik, 4) sikap social sebagian besar baik, 5) keterampilan berpikir kritis siswa rata-rata sudah baik. Berkenaan dengan unsur utama penelitian ini, maka dapat disimpulkan 1) merancang dan melaksanakan pengamatan dan 2) mengumpulkan data perlu ditingkatkan

    The research was aimmed at studying (1) Determine the percentage of wheat flour,sweet corn and skin dragon fruit right in the manufacture of dry noodles that can beaccepted by consumers, and (2) Determine the influence of addition of sweet corn andrind of a dragon on the content of moisture, ash, protein, and preferences ofconsumers towards the parameters of color, flavor, elasticity, and sensory overall.The method used in this study is a factorial experimental design with two factors,namely the substitution treatment of sweet corn pasta and red dragon fruit skinextracts of the flour. Substitution of sweet corn used is 10%, 20% and 30%. Mediumaddition of dragon fruit peel extract of 5%, 10% and 15%. Each experiment carriedrepeat 3 times, so it will be acquired unit (unit) trial were 9 units trial. The dataobtained were tested with the test Barlett diversity and additional data with Tuckeytest. Furthermore, to see the value of the middle test treatment Significant Difference(LSD) at 5% level. The resulting dried noodles then analyzed the water content, ashprotein, the overall sensory test. Results from the study if seen from the test sensorypreferences overall, generally panelists prefer the treatment of sweet corn and dragonfruit with a concentration of 20%, 15% better than the taste, color and elasticity ofnoodles, while from the nutritional content of dried noodles sweet corn and dragonfruit SNI is in conformity with dry noodles

    Keberadaan logam berat dalam air limbah menimbulkan permasalahan yang serius bagi lingkungan. Usaha penanganannya telah banyak dilakukan dengan berbagai metoda. Metode yang relatif efektif dan efisien adalah metode adsorpsi. Penelitian ini bertujuan penyisihan logam Pb(II) dalam air limbah menggunakan bioadsorben kulit kacang tanah dengan sistem kolom. Pada rancangan percobaan, sebagai variabel tetap digunakan berat adsorben, yaitu sebesar 50 g, ukuran partikel 40 mesh dan volume adsorbat digunakan 10 liter, laju alir 7 liter/menit. Variabel bebas waktu adsorpsi 0; 10; 20; 30; 60; 90; 120; 150; 180; 210; 240 menit dan jenis adsorben: tanpa aktivasi, aktivasi fisik dan aktivasi kimia (H2SO4 1N dan NaOH 1N). Hasil penelitian menunjukan bahwa adsorpsi logam Pb(II) dipengaruhi oleh waktu dan aktivator. Model kinetika adsorpsi memenuhi kinetika pseudo orde dua dengan kapasitas adsorpsi kesetimbangan (qe) terjadi pada waktu 210 menit untuk tanpa aktivasi sebesar 2,387 mg/g, aktivasi fisika sebesar 1,896 mg/g, aktivasi H2SO4 1N 2,768 mg/g dan aktivasi NaOH 1N 2,991 mg/g. Persen masa penyisihan Pb(II) tertinggi untuk tanpa aktivasi 64,98%, aktivasi fisika 59,21%, aktivasi dengan H2SO4 86,02% dan aktivasi dengan NaOH 1N 96,57%

    A review of using the force/torque sensor in robotics application

    Get PDF
    Nowadays, force/torque sensors ubiquitous in the robotics field. Most of the robots on the assembly line use a force/torque sensor in a complex assembly process. A force/torque (F/T) sensor is an electronic device designed to track, detect, record, and manage the rotational and linear forces exerted on it. This force/torque sensor, sometimes known as a multi-axis force/torque transducer, six-axis load cell, or F/T sensor. This sensor plays a vital role in the robotic application as it provides force information to make the system more reliable and precise.

    Hydraulic bearing puller

    A bearing puller tool is an essential repair aid when working on an engine or machine that has pressure-set bearings in its mechanisms. Without the tool, repair of bad bearings would be difficult and prone to a high risk of damage to the shaft or casing block of gearbox and engine. It is designed as a tool to make the removal and installation of bearings simple and efficient, bearing pullers often resemble a pair of scissors. In some cases, the configuration of the puller will allow the extraction of both gears and bearings, including those that are connected with a series of shafts within the mechanism. Different sizes of bearing pullers make it possible to use the device on everything from a pair of skates to complicated industrial machinery. ‘Hydraulic Bearing Puller' is one of the products that have been modified from the original product in the market. Extensive studies have been conducted on service centers to implement this product. Most workers remove the bearing from the shaft (shaft) a way tap so that it can be removed. Apart from that they also use the 'bearing puller' common but with high cost. From the original product, we have made modifications to equipment for easy used by employees
