Abstract

The allocation of LPG gas subsidies has increased, putting a burden on state finances, while surplus electricity production is not being utilized optimally. Electrical energy can replace LPG gas by replacing the gas stove with an electric stove. This conversion requires adequate installation to ensure the safe and secure operation of the electric stove. The implementation of the conversion program must be supported by community readiness regarding standard electrical installations for electric stoves in the form of training. Training activities were carried out in Nyurlembang Village, Narmada, West Lombok, as a community service activity. This activity aims to educate and train the public about repairing and redesigning electrical installations for electric stoves. Training methods include lecture, discussion and practice methods. Before and after the activity, participants are given a written test to determine the success of the training activity. The test results show an average score before and after training of 38.33 and 66.00 for the range 0-100. These results show that the training was quite effective with an increase in participants' theoretical and practical knowledge of 27.67.

Abstract

Speech recognition technology makes human contact with the computer more accessible. There are two phases in the speaker recognition process: capturing or extracting voice features and identifying the speaker's voice pattern based on the voice characteristics of each speaker. Speakers consist of men and women. Their voices are recorded and stored in a computer database. Mel Frequency Cepstrum Coefficients (MFCC) are used at the voice extraction stage with a characteristic coefficient of 13. MFCC is based on variations in the response of the human ear's critical range to frequencies (linear and logarithmic). The sound frame is converted to Mel frequency and processed with several triangular filters to get the cepstrum coefficient. Meanwhile, at the speech pattern recognition stage, the speaker uses an artificial neural network (ANN) Madaline model (many Adaline/ which is the plural form of Adaline) to compare the test sound characteristics. The training voice's features have been inputted as training data. The Madaline Neural Network training is BFGS Quasi-Newton Backpropagation with a goal parameter of 0,0001. The results obtained from the study prove that the Madaline model of artificial neural networks is not recommended for identification research. The results showed that the database's speech recognition rate reached 61% for ten tests. The test outside the database was rejected by only 14%, and 84% refused testing outside the database with different words from the training data. The results of this model can be used as a reference for creating an Android-based real-time system.

Abstract

The mangosteen fruit has a characteristic thick skin, so it is difficult to know the condition of the flesh. Farmer can only know damage to the fruit flesh after the fruit skin had opened. Detection of the quality of the mangosteen flesh can be detected using a sensor capable of penetrating the thickness of the mangosteen rind. Flesh quality detection is carried out based on the S21 value (attenuation of mangosteen flesh value) using a portable device equipped with a sensor and capable of emitting microwaves. The S21 value of the fruit's flesh was measured using a spiral resonator that functioned as a sensor. The prototype device consists of an oscillator circuit, a power splitter, and a phase detector with 2507 MHz. Fruit flesh had divided into two conditions: damaged for fruit flesh with yellow sap or Translucent Flesh Disorder, and suitable condition for clean fruit flesh. The results showed that the fruit flesh had an average S21 value of 7.041 dB for damaged flesh and 6.007 dB for good flesh condition. The difference in the value of S21 had used as a reference for detecting the shape of the fruit flesh, with the detection threshold calculated by the Support Vector Machine, resulting in a threshold value of 6.712 dB.

Abstract

Bayan Village, located in Bayan District, North Lombok Regency, West Nusa Tenggara Province, has great potential in the agricultural and plantation sectors due to its strategic location at the foot of Mount Rinjani. The fertile soil in this village allows residents to grow various crops, including coffee. However, most residents only sell coffee in raw form without going through the processing process, so the added value of coffee products is not optimal. To overcome this, a workshop was held on processing robusta coffee into robusta coffee powder and cascara tea as an effort to optimize the productivity of MSMEs in Bayan Village. This workshop aims to increase the productivity of MSMEs by processing coffee into high-value products. In addition to increasing economic value, this workshop is also expected to reduce coffee skin waste in Bayan Village and provide additional sources of income for residents. Thus, Bayan Village can be an example of a village that has succeeded in optimally utilizing its natural potential, creating new jobs, increasing residents' income and contributing to sustainable village economic growth.

Abstract

In recent years, it noted that the number of requests for blood from hospitals in West Lombok and Mataram exceeded the bloodstock in the PMI Blood Transfusion Unit (UTD) in West Lombok Regency. The blood requests need predicting so there is no shortage of bloodstock. The model of the Backpropagation artificial neural network method is used to estimate the number of short-term blood requests. Predictive performance is analyzed based on the accuracy value based on the Absolute Maximum Percent Error (MAPE). The use of backpropagation neural networks can help respond to emergencies faster and predict more accurately. Accuracy rate prediction results for some type of blood component are: Whole Blood Bank Blood Hospital (WB BDRS) of 22%, BDRS Packet Red Cell blood of 78%, Thrombocyte Concentrate BDRS blood of 84 %, Fresh Frozen Plasma BDRS blood of 80%, WB NON-BDRS blood of 18%, PRC NON-BDRS blood of 66%, TC NON-BDRS blood of 55%, and FFP NON-BDRS blood of 47%. Based on these results, the JST backpropagation method can be used to predict TC BDRS blood and FFP BDRS blood with a good category.
