Power converter for dual-power photovoltaic-grid energy system / Intan Rahayu Ibrahim

High frequency switching activities of power electronic devices in the power converter produce switching losses, harmonic distortions and raise high voltage and magnetic stresses in the power converter circuit, consequently affecting the efficiency and quality of output of the converter. In this research study, a new power converter utilizing low fundamental frequency switching technique is being proposed to resolve harmonics distortion issues. This research aims to develop switching and control technique for power converter in dual-power photovoltaic-grid energy system. 21level cascaded H-bridge multilevel inverter is developed by cascading five of 5-level H-bridges with five separate PV sources. 5-level H-bridge produces high level of output "stepped" voltage with reduced number of power switches. The optimized switching strategy of proposed MhyPSO technique successfully reduced the THD level to 3.94% in the simulation circuit and 6.7% in the hardware circuit. Each of 5level H-bridges is equipped with the individual boost regulator embedded with MPPT and battery management system. The operation and the synchronization of the power converter system is digitally controlled to ensure the system works at the maximum captured power and produces fixed 240V, 50Hz power supply in variation of environmental conditions. The supervisory controller administers the transition of supply and mode of operation, meanwhile, the converter controller commands electronic switches in power converter components. It is verified in the simulation works, the boost regulator circuit is capable of tracking maximum power point and boosting the PV module voltage to 72V. The simulation analysis of the battery management circuit verified that the algorithm implemented is succeeded in detecting PV current, evaluating charging mode and regulating charging current. The switch over circuit and supervisory controller is capable of monitoring the PV current and trigger the transition of power supply whenever PV current is below or above the pre-set condition. The transition delay recorded during the transition of power supply are 2.2ms and 4ms for transition of supply power from PV to grid and grid to PV respectively. All simulation works are verified with the experimental findings and it is concluded that all the research objectives have been achieved

PENGARUH PENAMBAHAN TEPUNG DAUN JAMBU BIJI DAN ARANG AKTIF PADA RANSUM PUYUH PETELUR (Coturnix coturnix japonica) TERHADAP PRODUKTIFITAS MASA PUNCAK PRODUKSI

This study aims to determine the effect of adding guava leaf flour and activated charcoal to laying quail rations on productivity during peak production. The method used was experimental with a factorial complete randomized design, consisting of 4 treatments and repeated 6 times, treatment variations of two factors guava leaf flour (JB) and activated charcoal (AA) namely, P0 (100% control feed), P1 ( P0 + 0.5% JB + 0.5% AA), P2 (P0 + 0.5% JB + 1.0% AA), P3 (P0 +1.0% JB + 0.5% AA). The material used was 240 laying quails aged 90 days. Variables observed included feed consumption, egg production and FCR. The results of this study showed that the addition of guava leaf flour and activated charcoal to laying quail rations during peak production had no significant effect (P<0.05) on feed consumption with the lowest number at P0, namely 25.01 gram/head/day, egg production the highest was at P1 which was 92.36% and the lowest FCR was at P1 which was 2.47. The conclusion of the addition of guava leaf meal and activated charcoal to laying quail rations on peak production productivity had no significant effect on feed consumption, egg production and FCR

NEEDS ANALYSIS FOR ESP COURSE DEVELOPMENT FOR UNDERGRADUATE ENGINEERING STUDENTS

Abstract This research is aimed at finding out the target needs, in terms of necessities and lacks, relevant to engineering work context, and investigating the learning needs as the route to meet the target needs. A cross-sectional survey as research design was employed. The data were gained from the semi-structured interview to three representatives of English lecturers for engineering and the questionnaire to ninety fourth-year engineering students in the Faculty of Engineering in one of universities in Bandung. The results reveal that engineering students’ English proficiency has not met the target needs provoked by the majority lacks of communication skill, particularly speaking fluently and giving an oral presentation. With this in mind, some preferred-learning needs to overcome the lacks are the significance use of a good combination material, the use of internet as a media, working in a small group and in pair as learning partner, having a simulation related to engineering work context, problem solving, and an oral presentation. This research is expected to contribute towards the Faculty of Engineering in developing and evaluating the English course design relevant to the current demand and English lecturers in planning and conducting instruction in line with engineering students’ preference in learning English;--- Penelitian ini bertujuan untuk mengetahui kebutuhan sasaran, yang mencakup kebutuhan dan kelemahan, yang berhubungan dengan konteks pekerjaan keahlian teknik, dan mengetahui kebutuhan pembelajaran sebagai cara untuk mencapai kebutuhan sasaran. Penelitian ini menggunakan survey kros-seksional. Hasil penelitian menunjukkan bahwa kemampuan bahasa Inggris mahasiswa teknik belum memenuhi kebutuhan sasaran yang disebabkan oleh kelemahan terbesar dalam kemampuan berkomunikasi, terutama berbicara dengan lancar dan presentasi dalam bahasa Inggris. Oleh karena itu, untuk mengatasi kelemahan tersebut, beberapa kebutuhan belajar bahasa Inggris yang dipilih mahasiswa adalah pentingnya penggunaan materi yang dikombinasikan dengan baik, penggunaan internet sebagai media, belajar dalam kelompok kecil dan pasangan sebagai teman belajar, simulasi yang berhubungan dengan konteks pekerjaan teknik, penyelesaian masalah, dan presentasi dalam bahasa Inggris. Penelitian ini diharapkan dapat berkontribusi terhadap Fakultas Teknik dalam mengembangkan dan mengevaluasi rencana pembelajaran bahasa Inggris yang sesuai dengan tuntutan saat ini, dan untuk dosen bahasa Inggris dalam menrencanakan dan mengimplementsikan rencana pembelajaran sesuai dengan preferensi mahasiswa teknik dalam belajar bahasa Inggris

PERBANDINGAN ASUPAN GIZI DAN STATUS GIZI ANTARA MAHASISWA ANGKATAN 2015 DENGAN ANGKATAN 2016 JURUSAN PENDIDIKAN OLAHRAGA FIO UNESA

Abstrak Mahasiswa merupakan remaja dengan kisaran usia antara 18-22 tahun yang merupakan periode rentan gizi, sehingga perlu asupan makan yang mengandung jumlah zat gizi yang lebih tinggi daripada orang dewasa. Kondisi mahasiswa angkatan 2016 dan 2015 di Jurusan Pendidikan Olahraga FIO Unesa memiliki bentuk tubuh yang beragam. Angkatan 2016 memiliki jadwal kuliah lebih padat, sehingga memerlukan asupan makanan yang memenuhi kebutuhannya. Sedangkan perkuliahan angkatan 2015 hanya fokus di skripsi dan mata kuliah yang mengulang saja, namun asupan makanannya sama seperti angkatan 2016. Tujuan penelitian ini yaitu untuk mengetahui perbedaan dan mana yang lebih baik asupan gizi dan status gizi antara mahasiswa angkatan 2015 dengan angkatan 2016 Jurusan Pendidikan Olahraga FIO Unesa. Jenis penelitian yang digunakan adalah non-eksperimen dengan menggunakan pendekatan kuantitatif. Teknik sampel yang digunakan adalah purposive sampling. Subjek dari penelitian ini adalah mahasiswa angkatan 2015 dan 2016 Jurusan Pendidikan Olahraga masing – masing sejumlah 30 mahasiswa. Instrument yang digunakan ialah IMT dan formulir food recall 24 jam. Teknik analisis data yang digunakan ialah uji t dan Mann Whitney Test. Berdasarkan analisis data diperoleh: uji t IMT (status gizi ) diperoleh nilai 0,93, dan nilai tersebut di atas 0,05, maka tidak terdapat perbedaan yang signifikan. Uji t asupan gizi diperoleh nilai 0,004, dan nilai tersebut di bawah 0,05, maka terdapat perbedaan yang signifikan. Uji t karbohidrat diperoleh nilai 0,000, dan nilai tersebut di bawah 0,05, maka terdapat perbedaan yang signifikan. Uji t lemak diperoleh nilai 0,08, dan nilai tersebut di atas 0,05, maka tidak terdapat perbedaan yang signifikan. Dari Mann-Whitney Test protein diperoleh nilai r 0,48, dan nilai tersebut di atas 0,05, maka tidak terdapat perbedaan yang signifikan. Jadi terdapat perbedaan asupan gizi dan karbohidrat mahasiswa angkatan 2015 dan 2016. Asupan gizi dan karbohidrat lebih baik angkatan 2015 daripada 2016. Dan tidak terdapat perbedaan status gizi, lemak dan protein pada angkatan 2015 dan 2016, karena mempunyai nilai rata – rata yang relatif sama.
