Judul: Implementasi teknologi mobile agent pada sistem pemantauan jaringan komputer
Abstrak: Due to increasing network complexity, monitoring of performance in a computer network is needed. This monitoring is expected not to burden the existing bandwidth capacity, to prevent the network from data access speed reduction. The goal of this research is to implement the mobile agent technology for computer network monitoring. The protocol used in the network monitoring is the Simple Network Management Protocol (SNMP). In the system architecture, the network divided into three parts, namely Network Manager (NM), Network Element (NE) and the Network Device (ND). The SNMP requests will be performed by the mobile agent which is sent to each NE. An NE might be connected to several NDs. The mobile agent residing in the NE will collect the monitored result, and provide it to the mobile agent that act as the collector. The collector brings reports from the NEs and subsequently submit them to the mobile agent residing in NM to be represented as a report in a graphical form. From this experiment, mobile agent technology can reduce the activity of data transfer in packet size and bytes of data during the monitoring process performed. Application of mobile agent can save bandwidth up to 80% compare to the standard client server architecture. Mobile agent technology can provide solution in the development of distributed data system by considering some aspects of the system needed to be developed.

Judul: Implementasi Teknologi Mobile Agent pada Layanan Printer Berbasis Lokasi
Abstrak: Most devices in ubiquitous network environment have limited memory and processing power, thus they can’t provide all services even when in suitable locations. Mobile agent technology could be implemented to improve resource efficiency. The goal of this research is to implement mobile agent technology for location-based printer service. In this research a scenario-based UML design analysis method will be used. To develop the system with mobile agent technology, a state-of-theart agent platform – JADE is used. The system consists of four parts: (1) mobile agent server, (2) location-based service server, (3) printer service, (4) client. Mobile agent is successfully implemented for location-based services. There are several advantages of mobile agent for location-based services: (1) can be used as alternative solution to distribute services in ubiquitous computing environment, (2) service management is easier and cheaper because no additional infrastructure needed when new service added, (3) easy to maintain because system consists of an agent that easy to debug and agent component easy to replace without affecting other component in the system, (4) system model is highly scalable. However, there are also disadvantages of mobile agent for location based services: (1) specifically in this case, the network infrastructure needs the addition of two computer equipment that will act as mobile agent server and location-based service server, (2) mobile agent security is still an open research. Our future researches are to include more service available, improve client graphical user interface, considering geographical proximity between service requester and provider, add compatibility with more operating system, improve jobs distribution algorithm and add domain name system entity

Judul: Hubungan antara pertumbuhan pucuk, perkembangan buah, serta tingkat kandungan asam indol asetat di dalam biji dan layu pentil kakao (Theobroma cacao L.)
Abstrak: Sejak terbentuk sampai masak buah kakao memerlukan waktu 150 - 170 hari. Dalam 85 hari pertama masa perkembangannya buah kakao dapat mengalami kematian fisiologis yang disebabkan oleh faktor internal tanaman. Buah kakao dalam periode ini disebut pentil(cherelle) dan gejala kematiannya disebut layu pentil (cherelle wilt) karena gejala layu yang tampak pada awal kematiannya. Pentil kakao yang mati tidak gugur seperti pada tanaman buah-buahan X lainnya melainkan tetap tergantung pada batang tempat tumbuhnya.
