Abstract

Solar panels have constraints on output power that are not large enough and they are highly depend on natural conditions. Solar panel power depends on the intensity of sunlight received and the temperature of the surrounding environment. In order to get the maximum output power of the solar panel, an additional device called the solar tracker is needed. This research has contributed to increasing the output power of solar panels by directing solar panels perpendicular to sunlight. The use of this research is very useful in the application of the multi-axis tracker application from the sun. By knowing the rising angle of the sun every morning and the circulation angle to sunset, the tracker will work quickly so that the energy used for movement is very small. The reference angle generated by the ANFIS training algorithm is more accurate because the calculated data will be confirmed again by the sensor. And this system can work offline, without being connected to a data center, so it can be used in remote or isolated areas.Keywords : Sun Tracking System, MPPT, ANFIS, Solar Panels AbstrakPanel surya memiliki kendala pada daya keluaran yang tidak cukup besar dan sangat tergantung oleh kondisi alam. Daya panel surya sangat tergantung dari intensitas cahaya matahari yang diterima dan suhu lingkungan sekitar. Agar mendapatkan daya keluaran panel surya yang maksimal dibutuhkan perangkat tambahan yang disebut tracker matahari. Penelitian ini memiliki kontribusi dalam meningkatkan daya keluaran panel surya dengan mengarahkan panel surya tegak lurus dengan cahaya matahari. Penggunaan penelitian ini sangat bermanfaat dalam penerapan aplikasi tracker multiaxis dari matahari. Dengan mengetahui sudut terbitnya matahari pada setiap pagi hari dan sudut edar sampai dengan terbenam, tracker akan bekerja dengan cepat sehingga energi yang digunakan untuk pergerakan sangat kecil. Sudut referensi yang dihasilkan oleh algoritma pelatihan ANFIS, lebih akurat karena data hasil perhitungan akan dikonfirmasi kembali oleh sensor. Serta sistem ini dapat bekerja secara offline, tanpa terhubung dengan pusat data, sehingga dapat digunakan pada area terpencil atau terisolasi.Kata Kunci : Posisi Sudut Matahari, MPPT, ANFIS, Panel Surya

Abstract

Generally, Electronic Load Control (ELC) used in micro hydro power plant (MHPP) to controls the voltage between consumer load and a dummy load, still detects one parameter voltage or frequency generator only. Whereas in reality, any changes in the load on consumers, generator voltage and frequency also changed. When the consumer load down the electric current will be supplied to the dummy load, amounting to decrease in consumer load. When there is a transfer load, there will be distortion voltage and frequency, thus a special methods to reduce distortions by speeding up the process of transferring the electric load is needed. The proposed of this study is using fuzzy logic algorithm.To realize such a system, a comparison tool model of load control digital electronic fuzzy logic controller (FLC) and Proportional Integrator (PI) is required. This modeling using matlab program to simulate, the simulation result shows that the ELC based  on fuzzy logic controller is better than conventional PI control, it seen from fast response to steady state condition.

Abstract

The most prominent protocols for data transfer in internet of things (IoT) are message queuing telemetry transport (MQTT) and constrained application protocol (CoAP). The existing clients from both sides are unable to communicate directly because of the packet’s header structure difference in application and transport layer. In response, this paper aims to develop a bidirectional conversion server used to translate the specified messaging protocol interchangeably in the OpenFlow network and transmit the converted packet from both sides. The conversion server integrated the MQTT subscriber and CoAP POST object for converting the MQTT message into CoAP data. Similarly, the CoAP-MQTT translation was processed by CoAP GET and MQTT publisher object. The research was evaluated by analysing the round trip time (RTT) value, conversion delay, and power consumption. The RTT value for MQTT-CoAP required 0.5 s while the CoAP-MQTT was accumulated in 0.1 s for single-packet transmission. In addition, the SDN controller and the conversion server only consumed less than 1% central processing unit (CPU) usage during the experiment. The result indicated that the proposed conversion server could handle the translation even though there was an overwhelming request from the clients.

Abstract

Maternal mortality rate (MMR) in Indonesia intercensal population survey (SUPAS) was considered high. For pregnancy risk detection, the public health center (puskesmas) applies a Poedji Rochjati screening card (KSPR) demonstrating 20 features. In addition to KSPR, pregnancy risk monitoring has been assisted with a pregnancy control card. Because of the differences in the number of features between the two control cards, it is necessary to make agreements between them. Our objectives are determining the most influential features, exploring the links among features on the KSPR and pregnancy control cards, and building a machine learning model for predicting pregnancy risk. For the first objective, we use correlation-based feature selection (CFS) and C5.0 algorithm. The next objective was answered by the union operation in the features produced by the two techniques. By performing the machine learning experiment on these features, the accuracy of the XGBoost algorithm demonstrated the hightest results of 94% followed by random forest, Naïve Bayes, and k-Nearest neighbor algorithms, 87%, 66%, and 60% respectively. Interpretability aspects are implemented with SHAP and LIME to provide more insight for classification model. In conclusion, the similarity feature generated in the two interpretation approaches confirmed that Cesar was dominant in determining pregnancy risk.

Abstract

PLTMh (Pembangkit Listrik Tenaga Mikrohidro) merupakan salah satu sumber energi terbarukan yang ramah lingkungan. Desa Karangsuko Kec. Pagelaran Kab. Malang merupakan desa yang mempunyai banyak sumber air, antara lain Sumber Taman, Sumber Suko dan Sumber Jeruk. Sumber air yang sudah dimanfaatkan sebagai penghasil listrik adalah sumber maron dengan menghasilkan listrik sebesar 22 KW, dimana listrik yang dihasilkan dimanfaatkan oleh BPAB&S untuk menjalankan 2 buah pompa air dan warung-warung atau kios-kios yang ada di sekitar tempat wisata sumber maron. Pompa air tersebut berfungsi untuk memindahkan air dari sumber maron ke beberapa tandon, masyarakat mendapatkan air bersih dari jaringan tandon ke rumah-rumah penduduk. Permasalahan saat ini adalah masih ada 1 buah pompa air yang masih disupply PLN, sehingga tiap bulan pihak pengelola harus membayar ke PLN sekitar Rp. 15.000.000,-. Sementara kurang lebih berjarak 500 meter dari lokasi PLTMh yang ada saat ini, ada sumber air yang bernama sumber jeruk yang sepintas debitnya lebih besar dari sumber maron. Berdasarkan hipotesa, di lokasi sumber jeruk berpotensi dibangun sebuah pembangkit listrik tenaga mikrohidro. Sebelum dibangunnya suatu PLTMh, maka dibutuhkan studi kelayakan (Feasibility Study) untuk melihat secara teknis dan ekonomis apakah sebuah PLTMh layak atau tidak layak untuk dibangun. Tujuan kegiatan pengabdian ini adalah untuk membuat feasibility study pembangkit listrik tenaga mikrohidro dengan melakukan mengidentifikasi potensi sumber daya air dan menilai tingkat kelayakan. Metode yang digunakan adalah metode PRA (Participatory Rapid Appraissal), yakni metode pemberdayaan yang bersifat Partisipatif dan Bottom-up Approach, yaitu dengan melakukan kegiatan pengukuran kondisi hidrologi, pemilihan lokasi dan layout dasar, desain teknik PLTMh. Hasil simpulan berdasarkan pengukuran dan perhitungan diperoleh Debit desain (Q) = 1,10 m3/dt, tinggi jatuh gross (H) = 6,00 m, Daya terbangkit (P) = 50,00 kWatt.

Abstract

Processing data in an institution or organization has become an activity or routine for each meeting. In processing data, of course there are various kinds of problems, ranging from missing data, either because of an error in entering data or the result of a system failure. To overcome these problems, in an agency or company must have data backup, so as to create problems that occur in the data, the institution still has data backup. To call, another method of database replication is used. From the test results obtained data on the value of RTA (Round Trip Average) that is the time required for one time sending and receiving data from the replication database is 5426.22 ms and for compilation service diagrams a query attack occurs with a percentage of 29% in the database applications that produce 1774.45 ms results and for service diagrams at a query attack percentage of 29% a single database estimates the server down.
