Web-based learning environment based on students’ needs

Traditional learning needs to be improved since it does not involve active learning among students. Therefore, in the twenty-first century, the development of internet technology in the learning environment has become the main needs of each student. One of the learning environments to meet the needs of the teaching and learning process is a web-based learning environment. This study aims to identify the characteristics of a webbased learning environment that supports students’ learning needs. The study involved 542 students from fifteen faculties in a public higher education institution in Malaysia. A quantitative method was used to collect the data via a questionnaire survey by randomly. The findings indicate that the characteristics of a web-based learning environment that support students’ needs in the process of learning are online discussion forum, lecture notes, assignments, portfolio, and chat. In conclusion, the students overwhelmingly agreed that online discussion forum is the highest requirement because the tool can provide a space for students and teachers to share knowledge and experiences related to teaching and learning

Pemanfaatan Air Laut Sebagai Alternatif Irigasi Pada Tanaman Jagung Semi (Zea Mays L.)

Baby corn (Zea mays L.) atau jagung semi merupakan bahan sayuran segar yang diperoleh dari tongkol jagung muda yang awalnya hanya hasil sampingan dan kemudian dibudidayakan secara khusus (Soemadi, 2000). Dengan meningkatnya penduduk di Indonesia maka kebutuhan akan air bersih juga harus terpenuhi. Oleh sebab itu untuk mengurangi kebutuhan akan air bersih di bidang pertanian maka pemanfaatan air laut yang berlimpah dapat dijadikan sebagai bahan irigasi pada tanaman jagung semi. Tujuan penelitian ini untuk memanfaatkaan air laut untuk digunakan sebagai air irigasi pada tanaman baby corn dan mendapatkan konsentrasi air laut yang sesuai sebagai irigasi tanaman baby corn. Penelitian ini dilaksanakan di Greenhouse STPP, Malang, Jawa Timur pada bulan Januari- Maret 2015. Penelitian disusun menggunakan Rancangan Acak Kelompok (RAK). Bahan yang digunakan yaitu benih jagung varietas Bisi-2 dan pemberian irigasi yaitu 100% air tawar sebagai kontrol, 500 ppm, 1000 ppm, 1500 ppm, 2000 ppm, 2500 ppm, 3000 ppm, 3500 ppm, dan 4000 ppm. Pengamatan meliputi parameter pertumbuhan (tinggi tanaman, total luas daun dan umur berbunga ) dan komponen hasil panen (panjang tongkol, diameter tongkol, dan bobot segar tongkol). Hasil penelitian menunjukkan bahwa Tanaman jagung semi yang diberi air laut sebagai irigasi hingga konsentrasi 4000 ppm dapat menghasilkan kuantitas jagung semi yang tidak berbeda terhadap perlakuan 100% air tawa

Dual Channel Double Wavelength Method in Optical Fiber Based Gas Sensor for Carbon Dioxide Detection

A novel double wavelength strategy in optical fiberbased sensor for detection of carbon dioxide (CO2) gas is presented. The detection strategy works based on an open-path direct absorption spectroscopy in the mid-infrared (mid-IR) wavelength range. The sensor system comprises of a broadband filament emitter acting as the Infrared (IR) light source, Chalcogenide Infrared (CIR) Optical Fibers, two Pyroelectric detectors which been fitted built- in with a limited bandpass CO2 channel and a reference channel. The sensor additionally uses calcium fluoride (CaF2) limit bandpass (NBP) channel for recognition of CO2 gas without cross-sensitivity to different gasses exist in the surrounding environment. The correlation amongst test and computed sensor yields are additionally exhibited

A Compact Optical Fiber Based Gas Sensing System for Carbon Dioxide Monitoring

This paper presents an approach to develop an optical fiber based gas leak sensor that can be used to detect and quantify carbon dioxide gas. The developed sensor system operates based on the principles of Infrared (IR) absorption spectroscopy using the dual channel and double wavelength method. Therefore, it is possible to eliminate the interference signal from the outside environment by using this method. The design of the Carbon Dioxide (CO2) gas sensor system consists of a Broadband light source, two IR detectors with different Narrow Band Pass (NBP) filters for Active and Reference channel, chalcogenide infrared (CIR) fibers and a compact gas detection cell. The output of the sensor system is captured using in-house LabVIEW program with Data Acquisition (DAQ) capabilities and displayed in real time. Experimental results show that the developed optical fiber based gas sensor system is capable to detect and quantify concentrations of carbon dioxide gas for leak detection and also environmental monitoring applications
