Abstract

In this research, water bath sonicator was fabricated to extract bioactive compound of plants material using sound energy (ultrasonic waves) and heater. The bioactive compound, flavonoid, has high sensitivity to temperature and extraction time and previous research stated best treatment with combination of 45˚C and 20 minutes. Therefore, fabricated water bath sonicator was equipped with proportional integral derivative (PID) based temperature controller and timer. Based on a calculation using the Ziegler-Nichols tuning method, Kp, Ki, Kd parameters are 16.59, 0.0279, and 2463.6, respectively. The experimental result shows that the PID controller can perform as design specification with overshoot 1.39%, error steady-state 0.688% and settling time 37.2 minutes. Furthermore, it was proven that the PID controller has contribution to extract more flavonoid.

Abstract

Inter-school teacher exchange has a significant role in achieving good and equitable quality of education. This has become the focus of North Sulawesi’s regional education office, particularly in the city of Manado at the level of the vocational high School (SMK). Inter-school teacher exchange, which still works on the basis of Microsoft Excel manually, is an obstacle to transparent and objective decision-making. Decision Support Systems (DSS) can be a solution to these problems. In this study, the Fuzzy Simple Additive Weighing (F-SAW) method was used for a web-based DDS. This test is carried out on five sample data through calculations using Ms. Excel and the DSS system with the acquisition of  decision values of 0.91 and 0.93, respectively.

Abstract

Document grouping is a necessity among a large number of articles published on internet. Several attempts have been done to improve this grouping process, while majority of the efforts are based on word appearance. In order to improve its quality, the grouping of documents need to be based on topic similarity between documents, instead of the frequency of word appearance. The topic similarity could be known from its latency, since the similarity of the word interpretation are often used in the same context. In the unsupervised learning process, SOM is often used, in which this approach simplifies the mapping of multi-dimension data. This research result shows that implementation of the latent structure decreases characteristic dimension by 32% of the word appearance, hence makes this approach more time efficient than others. The latent structure, however, when implemented on SOM Algorithm, is capable to obtain good quality result compared to word appearance frequency approach. It is then proven by 5% precision improvement, recall improvement of 3%, and another 4% from F-measure. While the achievement is not quite significant, the quality improvement is able to put the dominance of grouping process, compared to the original classification defined by the content provider.

Abstract

Road, as one of the land transportation infrastructure, is important for economic improvement of an area. It needs special and regular maintenance by the local government, in order to keep the road in good condition. For this purpose, the government conducts a survey with the aim of getting criteria for determining priority of road maintenance. The obstacle in implementation of road maintenance is the lack of criterias which make difficulties in determining the priority of road maintenance. Decision-making system is needed to solve the problems of determining the priority of road maintenance. Fuzzy Analytical Network Process (FANP) can solve the problem by calculating the criteria to get priority value. This method consists of many steps, namely weighting among criteria, weighting among sub-criteria, triangular fuzzy number, fuzzy synthesis, weight matrix, and priorities. The results show that the priority order of routine road maintenance is Jl. Jakarta, Jl. Kelud, and Jl. Kyai Tamin. The accuracy rate obtained in this research is 66.67%. Sensitivity test shows that the damage of the roads and the road density are important factors in generating the weight value road maintenance priorities.
