The microstrip antennas have different dimensions to get the desired performance, especially for microstrip antennas that have complex components and dimensions with the performance: the range of frequency at 2.4 GHz until 3.6 GHz, Maximum Power of Gain value is 5.83 dB and the minimum value is 3 dB and Maximum Directivity Value is 6.22 and the minimum value is 3.32. in consequence, needs to fill the demand for a new and the corresponding design as solvent to adaptive matching as tuner the frequency on antenna design that needs requires a complex mathematical method and simulation. This paper has the novel design to tune the performance of spade card microstrip antenna that can operate on the single, dual or multiband and able to produce circular or linear polarization using Backpropagation Neural Network in order to obtain an optimum design with a backpropagation algorithm as a solution to simplify the design process. As a result, after 20000 epochs the training loss is around 0.044 and the testing loss is around 0.058. The model has a good performance despite only using a few numbers of training data.

Waste is a major issue in the environmental field. Daily garbage in Malang City reaches 661.12 tons per day. Of this amount, 202.96 tons per day are managed by the people of Malang City. The remaining 458.16 tons per day is transported to the existing landfill in Supiturang. The composition of Malang city waste consists of organic waste (70.5%) and inorganic waste (29.5%); meanwhile, the potential of methane gas in the Supiturang landfill is based on the GIZ count of 4521 tons per year. Of this amount, only 3% has been utilized as a substitute for LPG gas by the public and as an electric generator drive, so this research uses the assessment of the potential development of the One Village-Owned Enterprises Urban Program on MSMEs in Malang, East Java Province, based on waste management in driving the community's economy as a most effective solution. This research is a quantitative developmental policy using the analysis of the critical problem and potential solutions. The variables to be explored are factors for the achievement of increased income source, Waste Management Strategies as Alternative Energy Sources and Drivers of Community Economy, regional core competencies and waste management.

A new approach has been developed to provide an overview about signal behavior in indoor environments using Cost-231 Multiwall Model (Cost-231 MWM) and Adaptive Data Rate (ADR) method. This approach used as a reference for access point (AP) placement for campus building. The Cost-231 MWM plays a role in estimating the measured power received by user (usually called as Received Signal Strength Indicator/RSSI) by considering the existence of obstacles around the transmitter (AP). We used Institut Asia Malang environments as the case study and gave some recommendations for AP placement: ten optimal placements for the first, third and fourth floor, also seven optimal placements for the second floor. These recommendations were based on the RSSI for good and excellent level signal (-50 dBm until -10dBm). This research also uses the Adaptive Data Rate (ADR) mechanism approach to reduce the amount of packet loss (kbps) resulting from obstacles that cause attenuation (-dB). With the Adaptive Data Rate mechanism, it means increasing the number of access points, the signal attenuation (-dB) occurs from the obstacles (Walls) that are penetrated by the Radio Frequency device and causes attenuation (-dB), the more Access points on the Multi-Wall, will allow communication and data transmitting stability.
