Judul: Rancang Bangun Penyesuaian Konten Web Mobile Learning Berdasarkan Konteks
Abstrak: Mobile Learning is a learning activity whose learners do not have to stay on a fixed location for a specific amount of time. In more recent times, not every mobile-based web application can successfully detect computational environment on client side. For mobile learning especially, failure to support multiple platforms can deteriorate learning process. This research proposed a mobile learning prototype application that could detect client’s computing environment by analyzing handset features and client’s current network speed state. Handset features detection can be achieved by using HTTP User Agent, while network speed state detection can be managed by using HTTP request delay detection. It also implemented the possibility of using JavaScript both as a server side scripting language with Node.js and document oriented database system using MongoDB.

Judul: Using WURFL (Wireless Universal Resource File) for client device detection and CMS (Content Management System) on m-learning development
Abstrak: Nowdays, most of the existing learning content has been designed for desktop computers and is not suitable for mobile devices with limited resources and computing capabilities. The main problem is that the screen size of mobile devices (cell phone, smart phone or PDA) is smaller than the screen size of desktop devices (personal computer or laptop). Therefore, we need to create a customized presentation for both types of devices to make learner feel comfortable when they learn. This paper presents an architecture to provide a good adaptation results for both types of devices. The architecture consists of two parts, the detection engine and the adaptation engine. The detection engine is responsible for detecting the client device based on devices capabilities provided by WURFL (user-agent, screen size, etc) and the adaptation engine is responsible for providing layout adaptation based on the results of detection and the requested content. The adapted content will be sent to the client by the server. Finally, the architecture has been successfully implemented in a website called KSB (Kasih Sayang Bunda) and also the CMS for managing articles. The system can also be continually updated to provide a good adaptation in the future. Key words: M-learning , WURFL, User-agent, Adaptation, CMS.

Judul: Ichthyoacanthotoxins pada Beberapa Jenis Catfish: Clarias gariepinus (Clariidae), Pangasius hypophthalmus (Pangasidae), Plotosus canius (Plotosidae)
Abstrak: Ichthyoacanthotoxins are toxins released through the pectoral fins (horn) by venomous fish. Order Siluroidea like CLARIAS GARIEPINUS, PANGASIUS HYPOPHTHALMUS, and PLOTOSUS CANIUS generally have pectoral fins as a defense mechanism. The research was conducted from February 2014 through September 2014 to determine anatomical structure of the venom gland and the chemical composition (acanthotoxins) present in the pectoral and dorsal spine. The results of histological analysis showed that the anatomical structure pectoral and dorsal spine consists of pieces of muscle, adipose layer, blood vessels, and there is a venom gland at CLARIAS GARIEPINUS with a long shaft, which is 1612.48 μm. The results showed that the proximate analysis, protein content of PLOTOSUS CANIUS is higher than the protein content of CLARIAS GARIEPINUS and PANGASIUS HYPOPHTHALMUS, while the fat content of CLARIAS GARIEPINUS higher than the fat content of PANGASIUS HYPOPHTHALMUS and PLOTOSUS CANIUS.
