DESIGN OF INDOOR ROBOT PROTOTYPE GUIDED BY RFID BASED POSITIONING AND NAVIGATION SYSTEM

In this study, a robot prototype was designed for indoor spaces guided by an RFID-based positioning and navigation system. First, the work area was prepared from cardboard material and RFID cards were placed at predetermined points in the work area. The unique ID number of each RFID card was defined and the coordinates of their location in the work area are known. The RFID reader in the robot prototype reads from less than 5 cm. With a basic approach, when the robot reads an RFID card that it passes over while in motion, the position of the robot is considered the same as the position of the card it is currently reading. The route is defined for the robot prototype whose location is known before starting the movement. When the robot reads a new RFID card during movement, it must move forward or turn left or right to reach the point where the next RFID card is located according to the route. This decision was predetermined and defined according to its location. Alphabot was used as the prototype. Arduino board and additional auxiliary sensors such as gyro sensor, speed sensors, distance sensors are placed on the prototype. The prototype robot is left at any point in the work area and arrives at a target point determined by the user. The required road route to reach the destination is calculated with the shortest path algorithm depending on the road network on the working area and the route is defined. Thus, it is ensured that the prototype reaches the target without any external intervention by the user other than target determination.

The Target Determination and the Mechanism of Action of Chiral-Antimalarial Drugs: A Docking Approach

Due to an undecided target and the prescription of chiral-aminoquinolines (chloroquine, primaquine and quinacrine) in the racemic form, the mechanism of action as well as the reason of causing side effects become unclear. Based on computationally evaluated literature data, the things determined theoretically were (i) the target of aminoquinolines during antimalarial activity, (ii) the mechanism of action of chiral-aminoquinolines and (iii) biologically active enantiomers of aminoquinolines. For the presented study, the enantiomeric binding affinities of aminoquinolines with all the targets claimed by other scientists were calculated, and then used in interpretation with the help of many investigations done/observed by others. The results were very interesting based on which, a new and acceptable mechanism of action of chiral-aminoquinolines during malaria curing step, is given for the first time. The current docking study not only resolves the questionable point about a definite target of aminoquinolines but also makes the mechanism of action understandable.

PENERAPAN METODE TOPSIS SEBAGAI PENGUKURAN DALAM PENETAPAN KANDIDAT CALON PENERIMA KIP PADA PERGURUAN TINGGI SWASTA (PTS)

Education and teaching are the rights of every citizen as regulated in the 1945 Constitution which is written in article 31, paragraph (1). However, the high cost of education sometimes becomes an obstacle for economically disadvantaged people, so that many secondary graduates are unable to continue their education to higher education even though they have good academic potential. The government has tried to provide a solution to this problem by organizing the Smart Indonesia Program (PIP) in helping its citizens obtain the right to higher education, namely through the provision of KIP Lectures that can be submitted by students at PTN and PTS. Private universities which act as facilitators for students in submitting KIP Lecture applications are expected to be more selective in the candidate selection process so that the distribution of assistance is right on target. Determination of KIP Lecture recipients based on certain criteria is often a problem in the decision-making process. To express the preferences of decision makers on the most desirable alternative, it can be done by applying the Technique For Order Preference by Similarity to Ideal Solution (TOPSIS). The TOPSIS method will be combined with fuzzy logic to determine the weight value for each criterion attribute, followed by a ranking process to select the best alternative, in this case a valid alternative as a beneficiary that fits the criteria. With this method, it is hoped that the assessment process will be more precise and accurate because it is based on predetermined criteria and weights.

The Use of AHP and GIS methods for zoning of flood prone areas in the North Medan region

Tidal floods that occur in the North Medan area due to overflowing of sea water when the tide enters the land, both directly and through river floods. The land area affected by tidal floods is getting wider and wider, so there needs to be an analysis of the level of vulnerability of tidal flooding so that the handling and prevention efforts can be on target. Determination of zonation with the level of tidal flood hazard involves various criteria, for this reason the AHP and GIS integration method is used to make rational decisions from several criteria and draw them on a zoning map. The results obtained in the North Medan area showed that 30.91 ha (0.33%) had very high levels, 1,515.98 ha (16.09%) had high levels, 4,411.92 ha (46.83%) had moderate levels, 3,176.83 ha (33.72%) had low levels, 284.81 ha (3.02%) had very low levels of vulnerability to tidal flooding.

Penerapan Metode Inferensi Fuzzy Takagi Sugeno-Kang Untuk Prediksi Hasil Panen Kelapa Sawit

Palm oil is one of the main crops and seeds in Indonesia. In oil palm plantations, oil palm crops are the most important things. Oil palm crops in the right time and quantity are what the farmers want. Therefore, harvest prediction using as reference of palm oil harvest target. Determination of harvest targets required a method that is able to predict the yield of oil palm. In this research, built a system of fuzzy inference with TSK method (Takagi Sugeno Kang), which aims to predict the yield of oil palm farmers. The fuzzy rules in the form of IF antecedent THEN are consequent, using consequent linear equations of the input variables. The coefficients of each variable of linear equation are consequently derived based on the expected yield of the harvest. The results of prediction testing of Palm Oil harvest production in 3 seasons, namely Dry Season, Rainy Season, Fertilization, input the number by values of variable with to the given range prove that the fuzzy inference of the TSK method can calculate palm il crop predictions well.

Target determination for transcranial magnetic stimulation in patients with a pharmacotherapy-resistant depressive episode based on the individual parameters of resting-state functional magnetic resonance imaging (a pilot blind controlled trial)

High-frequency repetitive transcranial magnetic stimulation (rTMS) is approved by the Food and Drug Administration (FDA) for the treatment of pharmacotherapy-resistant depressive disorders (DD). Individual target determination for stimulation can be one of the approaches that can increase the efficiency of the technique. Objective: to compare of the effectiveness and tolerability of standard and personalized rTMS protocols.Patients and methods. The investigation enrolled 30 patients with pharmacotherapy-resistant DD who were pseudo-randomized into two groups matched for age, gender, and episode severity. In the study group, the target was located at a point within the left dorsolateral prefrontal cortex (DLPFC) with maximum negative functional connectivity of the subgenual cingulate cortex. In the control group, the stimulation point was 5 cm anterior to the primary motor cortex (hand area). All the patients underwent 20 sessions of high-frequency rTMS DLPFC. For clinical evaluation, the investigators used the Beck Depression Inventory (BDI) and the 36-item Short Form Health Survey (SF-36) questionnaire before and after 10 and 20 rTMS sessions, respectively. Tolerability was assessed using the standardized questionnaires during and within 24 hours after each session. Results and discussion. The study group showed a significant reduction in BDI scores and an increase in the SF-36 (“Mental Health” section) scores after both 10 and 20 rTMS sessions; the control group had those only after 20 sessions. The two groups exhibited no significant differences in the reduction of BDI scores before and after 10 and 20 sessions, respectively. The investigation can be considered to be pilot in searching for algorithms to enhance the efficiency of rTMS DLPFC in pharmacotherapy-resistant depression using the algorithm for personification of target selection. It demonstrated the more rapid onset of a clinical effect in the study group patients. No serious adverse events were reported. The patients had dizziness, headache, and contraction of the facial muscles during the session; headache and mood changes within 24 hours after it. Conclusion. In both groups, rTMS was satisfactorily tolerated and effective; however, personalized target selection accelerated the onset of a clinical effect.
