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

Humans need access to information through cellular technology to support their activities, and will continue to increase with the times. This condition forces cellular service providers to continue to innovate to maintain quality to meet the various needs of their users, including in residential areas. Cellular service quality in housing can be determined using Quality of service (QoS) measurements, one of which is the Royal Medina housing complex in West Lombok Regency. The measurements of Quality of service values and signal level values are using the Wireshark and G-Nettrack Pro applications. In addition, measurements use the drive-test method. Based on the THIPON standard, the outdoor measurement results show that the throughput value is in a bad category, while the delay value is in the medium and bad category.

Abstract

Technology in agriculture continues to develop along with human needs. IoT technology has also been applied in agriculture, including oyster mushroom cultivation. Mushroom cultivation must pay attention to several aspects, among others: environment, temperature, and humidity during the maintenance period. The temperature in the barn must be maintained in the range of 25°C-30°C. The optimum air humidity required is between 70%RH and 90%RH. Mushroom farmers usually use existing experience in cultivating and developing oyster mushrooms. Changes in the barn can change suddenly, so it is necessary to observe the environmental conditions of the mushrooms regularly so that the mushrooms can develop optimally. So, it is necessary to build a system that can control humidity and temperature in mushroom cultivation. The system uses IoT-based technology to monitor the temperature and humidity in the mushroom-growing media with certainty so that mushroom growth becomes more optimal. The monitoring and temperature control system in oyster mushroom cultivation can run well while maintaining the temperature at 27.9% and humidity at 90.10% and can be displayed on the LCD Display.

Abstract

Sasambo batik is a traditional batik from the West Nusa Tenggara province. Sasambo itself is an abbreviation of three tribes, namely the Sasak (sa) in the Lombok Islands, the Samawa (sam), and the Mbojo (bo) tribes in Sumbawa Island. Classification of batik motifs can use image processing technology, one of which is the Convolution Neural Network (CNN) algorithm. Before entering the classification process, the batik image first undergoes image resizing. After that, proceed with the operation of the convolution, pooling, and fully connected layers. The sample image of Lombok songket motifs and Sasambo batik consists of 20 songket fabric data with the same motif and color and 14 songket data with the same motif but different colors. In addition, there are 10 data points on songket fabrics with other motifs and colors. In addition, there are 5 data points on Sasambo batik fabrics with the same motif and color and 5 data points on Sasambo batik fabrics with the same motif but different colors. The training data rotates the image by 150 as many as 20 photos. Testing with motifs with the same color shows that the system's success rate is 83.85%. The highest average recognition for Sasambo batik cloth is in testing motifs with the same color for data in the database at 93.66%. The CNN modeling classification results indicate that the Sasambo batik cloth can be a reference for developing songket categorization using a website platform or the Android system.

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

Parameter penting yang menjadi tinjauan baik buruknya sistem komunikasi  adalah Kualitas Bit Error Rate yang kecil, penggunaan bandwidth yang efisiensi, dan penggunaan emisi daya yang efisien. MC-DSCDMA dan OFCDM merupakan bentuk transmisi multicarrier hasil kombinasi dari dua teknik radio access yaitu OFDM (Orthogonal Frequency Division Multiplexing) dan CDMA (Code Division Multiple Access). Perbedaan utama kedua sistem terletak pada teknik spreading pada sub kanal. Pada penelitian ini akan disimulasikan dan dianalisis kinerja Bit Error kedua sistem. Pengujian kinerja Bit Error Rate dilakukan pada kanal AWGN dan Non Line Of Sight (NLOS) dengan modulasi QPSK. Pengujian dilakukan dengan merubah kenaikan SNR sebesar 1 dB sampai diperoleh batas ambang BER sebesar 10 – 3 . Analisis ini didasarkan pada nilai statistik rata-rata dari hasil program simulasi model sistem yang ditinjau dengan program Matlab Simulink 7.1. Berdasarkan analisa hasil pengujian, untuk kanal AWGN dengan batas ambang BER sebesar 10 – 3 diperoleh : model OFCDM baseband memerlukan level SNR sebesar 5,86 dB dan model MC-DSCDMA baseband memerlukan level SNR sebesar 7,98 dB. Pada Kanal NLOS, model OFCDM baseband memerlukan 2,44 dB  lebih kecil dibanding model MC-DSCDMA baseband yang masing-masing sebesar 10 dB dan 12.44 dB.
