Abstract

Educators are always looking for interesting and innovative ways in which to improve the communications skills of their students and in communicating with their students. This is even more important when the students are studying online. Weblogs, originally a simple web browser based system for updating websites, have developed into powerful web based content management systems, capable of acting as a platform for learning that can accelerate the development of expertise learner behaviour. There is a trend to utilize the benefits of the e-learning as a mechanism to improve learning performance of campus-based students. Whilst traditional methods, such as face-to-face lectures, tutorials, and mentoring, remain dominant in the educational sector, universities are investing heavily in learning technologies, to facilitate improvements with respect to the quality of learning. This study explores into the role of weblogs in supporting teachers during their teaching practice and the key factors determining their engagement with weblogs. Underlying our study is an integrative approach that puts weblogs alongside with other popular media in use. An online community was intentionally built with weblogs to facilitate reflection and social interaction among dispersed teachers. In parallel, multiple channels of communication were employed for peer interaction of students. Weblogs were perceived as valuable in relieving isolation, documenting their experience, and expressing their personal feelings. This study sustains our conviction that the integrative approach is vital to have a comprehensive picture of interaction among a community. Our study deepens the insights into the distinct benefit of weblogs as educational media and informs the future development of an online community with weblogs. Weblogs provide a chance for students to experience writing in a public space where their work can have real value both for their classmates and for a wider community. This prepares students for a networked world where communication is essential and often social and where writing can have consequences.

Abstract

Perubahan fisika dan kimia dalam timbunan kompos diteliti selama proses pengomposan limbah pembuatan botol yang terkontaminasi oleh gemuk (grease). Temperature awal menunjukkan peningkatan diikuti oleh penurunan secara bertahap pada akhir proses pengomposan. C:N rasio dan bahan tambahan nampaknya mempunyai pengaruh yang paling nyata dalam memproduksi temperatur tinggi. Proses pengomposan selama lima (5) bulan tidak menghilangkan kontaminan sampai batas yang dipersyaratkan. Oleh karena itu diperlukan waktu tambahan guna mengurangi kontaminan sampai level yang ditetapkan. Proses pengomposan ini berhasil dalam menghasilkan temperatur yang meningkat, namun parameter yang menyebabkan kenaikan temperatur tersebut masih belum jelas.

Abstract

Facebook (FB) dan WhatsApp (WA) telah menjadi "portal komunikasi" untuk jaringan sosial, yang telah dengan cepat mengubah cara orang berkomunikasi dan tetap terhubung. Dari perspektif pendidikan, situs jejaring sosial telah menerima ulasan ambigu. Beberapa penelitian telah menunjukkan bahwa penggunaan FB menjadi lebih luas dalam pembelajaran bahasa dan dapat menjadi alat yang efektif. FB tidak hanya mudah digunakan, tetapi juga membantu mendorong belajar mandiri dalam lingkungan sosial bagi siswa dan menempatkan kontrol untuk belajar ke tangan siswa. Artikel ini berfokus pada situs jejaring sosial FB, dan aplikasi WA dalam konteks UT. Ia mencoba untuk menjelaskan kegiatan berbagi informasi dilakukan melalui diskusi online menggunakan FB dan kelompok WA dan melibatkan siswa pembelajaran jarak jauh. Penelitian ini meneliti partisipasi siswa dalam diskusi online dan umpan balik mereka pada penggunaan FB dan forum WA sebagai platform untuk activity. FB dan WA diadopsi untuk mendukung tutorial online di Universitas Terbuka Indonesia dengan tujuan untuk meningkatkan guru-murid dan partisipasi rekan-berbasis, dan meningkatkan pengiriman pedagogis dan pembelajaran inklusif di ruang formal dan informal. Temuan menunjukkan FB dan WA berubah pedagogi dengan meningkatkan lingkungan sosial konstruktif untuk guru-siswa dan rekan-berbasis co-konstruksi pengetahuan. Peran guru berubah dari instruktur untuk fasilitator dan mentor memberikan bimbingan pada permintaan. Peran mahasiswa juga berubah dari penerima informasi ke generator informasi, kolaborator, organizer informasi / pencari / pemberi, pemikir kritis dan pemimpin kelompok. Namun tantangan menggunakan Facebook dan WhatsApp termasuk guru kebencian penggabungan akademik dan keluarga hidup disebabkan oleh konsultasi WhatsApp setelah jam. Facebook (FB) and WhatsApp (WA) have become the communication portal for social networking, which has rapidly transformed the way people communicate and stay connected. From an educational perspective, social networking sites have received ambiguous reviews. Some studies have shown that the use of FB is becoming more widespread in language learning and it can be an effective tool. FB is not only easy to use, but it also helps encourage autonomous learning within a social environment for students and puts control for learning into the students hands. This article focuses on the social networking site, FB, and WA application within the context of UT. It attempts to shed light on an information-sharing activity conducted via online discussion using FB and WA groups and involving distance learning students. This study investigated students participation in the online discussion and their feedback on the use of FBs and WAs forums as the platform for the activity.FB and WA were adopted for supporting an online tutorial at the Open University of Indonesia with a view to heighten tutorstudent and peer-based participation, and enhance pedagogical delivery and inclusive learning in formal and informal spaces. The findings suggest FB and WA transformed pedagogy by fostering social constructivist environments for tutorstudent and peer-based co-construction of knowledge. The teachers role was transformed from an instructor to a facilitator and mentor providing guidance on demand. Student roles were also transformed from information receivers to information generators, collaborators, information organizer/seekers/givers, critical thinkers and group leaders. However, the challenges of using Facebook and WhatsApp included tutor resentment of the merging of academic and family life occasioned by WhatsApp consultations after hours.

Study program S1 Agriculture Extension and Communication (S1 Agribusiness) in Universitas Terbuka (UT) has been opened since 2004.Starting from 2012.2, Agribusiness Studies Program established practicum guide as a guidance for students that do their practicums indepedently. Thisstudy aims to get students perceptions of self practicum management regardingthe implementation o independent practicum guidanceand analyzethe constraintsthat existin the fieldexperienced bythe students. The survey was conducted on students who took practicum t during 2013.1 to 2014.2 regisration period. A survey was performed by a questionnaire. The questionnaire asks three aspects of practicumimplementation which arepracticum guidance aspect, material aspect and  of practical support services aspect. Students perceptions regardingpractical implementation arepositive, although there are a tendencies of students have difficulties understanding the practical guidelines. They feel the guideline as not systematic and lacking details.. The language used in the guideline regarded by most non-extension students as difficult to understand. Students expect thepractical guide to be more detailed and clear. They said that it would be easier if at any part of the report is written in great detail of what should they fill, there should be an explanation of how the repot will be rated.Although in generalstudents have positive perceptions, there were some studentshad dificulties in accessing practicalguidance, obtainingmaterialsand tools, and havingqualified and competent instructor. Anotherconstraint felt by most ofthe studentsis the marks sometimes received out of schedule. Mulai masa registrasi 2012.2 Program Studi Agribisnis Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Terbuka (FMIPA-UT) menerapkan pelaksanaan praktikum mandiri dan memberlakukan Panduan Pelaksanaan PraktikumMandiri yang dirancang sebagai panduan bagi peserta praktikum untuk melaksanakan praktikum secara mandiri. Penelitian ini bertujuan untuk mendapatkan datapersepsi mahasiswa terhadap pedoman dan pelaksanaan praktikum mandiri, serta kendala-kendala di lapangan yang dialami oleh mahasiswa.Survei dilakukan terhadap mahasiswa yang mengambil praktikum pada masa registrasi 2013.1 sampai dengan 2014.2 dengan meminta mereka mengisi kuesioner. Kuesioner menanyakan tiga aspek dari pelaksanaan praktikum yaitu aspek pedoman praktikum, aspek materi praktikum dan aspek layanan penunjang praktikum. Persepsi mahasiswa terhadap pelaksanaan praktikum cukup positif, meskipun ada kecenderungan mahasiswa mengalami kesulitan memahami pedoman praktikum. Mereka merasakan panduan praktikum kurang sistematis dan detail. Bahasa yang digunakan dalam panduan oleh sebagian mahasiswa non penyuluh dianggap sulit dipahami. Mahasiswa mengharapkan panduan praktikum dibuat lebih detail dan jelas. Mereka mengatakan akan lebih mudah jika pada setiap bagian laporan dituliskan secara detail hal-hal yang harus mereka masukkan, jika perlu diberikan kisi-kisi penilaian laporan. Meskipun secara umum persepsi mahasiswa terhadap praktikum positif, namun masih ada sebagian mahasiswa yang mengalami kendala dalam hal mengakses panduan praktikum, memperoleh bahan dan alat praktikum serta tidak mudah mendapatkan instruktur yang kompeten. Kendala lain yang dirasakan sebagian besar mahasiswa adalah nilai praktikum yang tidak diterima sesuai jadwal.

Abstract

E-learning merupakan singkatan dari electronic learning, merupakan cara baru dalam proses belajar mengajar yang menggunakan media elektronik khususnya internet sebagai sistem pembelajarannya Universitas Terbuka (UT) memiliki aplikasi e-learning yang di beri nama Tuton (tutorial online) Sistem pembelajaran jarak jauh yang di gunakan UT sekarang sangat membantu dosen dan mahasiswa dalam proses belajar dengan memanfaatkan teknologi yang sudah maju seperti sekarang ini. Pada studi ini, kami mencoba menganalisis persepsi mahasiswa dan tutor dalam pemanfaatan fitur dan fasilitas Office 365 dalam tuton dan praktek online. Berdasarkan hasil pembahasan diperoleh kesimpulan bahwa Tanggapan terhadap perlu tidaknya fitur dipengaruhi oleh usia, gender, pendidikan, pelatihan tuton, dan aktivitas tuton. Kecuali pada fasilitas konferensi online dan berbagi cerita digital, tanggapan terhadap perlu tidaknya fasilitas dipengaruhi usia, gender, pendidikan, pekerjaan, pelatihan dan atau aktivitas tuton. Oleh karena itu, rekomendasi yang kami ajukan adalah diperlukan adanya kegiatan yang dirancang untuk mencapai optimalisasi pembelajaran jarak jauh antara lain penguatan lingkungan tuton dan prakton, perlunya peningkatan kompetensi TIK staf akademik dan keterlibatannya dalam tuton/prakton, perlunya peningkatan kapasitas pelayanan prima kepada semua pemangku kepentingan UT dan pengembangan dan peningkatan pelatihan penggunaan aplikasi standar dalam Moodle dan Office365 agar bisa saling melengkapi.

Abstract

Growth media waste of white oyster mushroom cultivation can be used as ruminant feed. We observed the nutrient content of the growth media waste. The focus is on the protein, carbohydrate, mineral and crude fiber. The protein, calcium and phosphor content of white oyster mushroom growth media waste is higher than the protein content in the media before it was used for mushroom cultivation. However, the fat content is lower after the media was used than control (the media before it was used). The difference is caused by microorganism degradation. The growth media waste can be used as ruminant feed up to 75 % of total forage dry matter without any negative effect.
