Karakteristik Buah dan Biji Kakao (Theobroma Cacao L.) pada Berbagai Altitude di Dataran Tinggi Dairi
Get PDFThe cocoa productivity is currently quite low quantity (454 kg ha-1) and quality, one of it caused by planting location of various altitude especially the highlands. The focus of this research were characteristic of cocoa pod and beans on several altitudes in Dairi highland. The research method were survey as purposive sampling on four altitudes as 860, 940, 1040, and 1120 m from sea levels (asl). The observed parameters were pod size, pod diametre, pod volume, dry weight of pod, dry weight of kolven, dry weight of beans, bean count per pod, dry weight per bean, pods value, and bean yield at 4 different altitudes in Dairi highland (>800 m asl) with 10 pods (replications) at each altitudes. The results of research showed that the increasing of altitude caused the decresed of pod size, pod diametre, pod dry weight, dry weight of beans, bean count per pod, dry weight each bean, pod value, and bean yield. The best pods and beans were at altitude of 860 m asl, namely fruit length 18.3 cm, fruit dry weight 118.6 g, beans dry weight 48.3 g, number of beans per fruit 43.7 and average weight per bean 1.10 g. The physical characteristics of cocoa pods and beans are still in the normal category

Sistem Pengontrol Kecepatan Mobil Ambulans Berbasis IoT Menggunakan NodeMCU ESP8266
Get PDFThis research introduces an IoT-based speed control system tailored for ambulance vehicles using the NodeMCU ESP8266 microcontroller. The system employs an optocoupler sensor to detect wheel rotation speed and transmits real-time data via Wi-Fi to the Blynk application. The objective is to ensure that the ambulance maintains safe operating speeds, while simultaneously activating alerts for the driver whenever thresholds are exceeded. Performance evaluations were conducted across GPRS, 3G, and 4G networks to assess reliability and responsiveness. The findings reveal a response latency of approximately 1 second on a 4G connection, and up to 3 seconds under GPRS. The proposed system exhibited strong network stability over a 24-hour test period and delivered accurate speed monitoring throughout. The novelty of this work lies in the seamless integration of real-time monitoring and alert mechanisms without reliance on manual intervention. This solution has potential application in improving the operational safety and efficiency of emergency medical transport services in Indonesia
Performance Analysis of Neural Networks With Backpropagation on Binary and Multi-Class Data Classification
Get PDFNeural networks represent a widely adopted paradigm within the domain of machine learning, employed for a multitude of classification endeavors, encompassing image recognition and natural language processing. This investigation seeks to elucidate the influence of varying neuron quantities in hidden layers on the efficacy of neural networks in both binary and multi-class classification endeavors. The research utilizes a dataset procured from images depicting characters and digits, which were transformed into binary format via a thresholding methodology. The neural network architectures comprise one and two hidden layers, which are trained employing the backpropagation algorithm in conjunction with the Adam optimizer. The evaluation of the models is conducted through metrics such as accuracy, loss curves, and confusion matrices. Findings reveal that the configuration featuring two hidden layers with 40 sampai 99 neurons achieves the pinnacle accuracy of 99.64 percent alongside optimal loss stability. Furthermore, models incorporating a single hidden layer exhibited commendable accuracy, thereby indicating that a reduced number of neurons can proficiently encapsulate data complexity in less demanding tasks. This research underscores the criticality of selecting suitable neural network configurations contingent upon data complexity and classification objectives, while advocating for further investigation into regularization strategies to enhance performance
ANALISIS KEBUTUHAN DAN KETERSEDIAAN AIR BERSIH DI WILAYAH MEDAN HELVETIA PELAYANAN SPAM MEBIDANG (MEDAN-BINJAI-DELI SERDANG)
Get PDFThe availability of clean water is a vital aspect in supporting the quality of life of the community, especially in densely populated urban areas such as Medan Helvetia District. This study aims to analyze the projection of clean water needs and availability for the next 50 years, and to assess the balance between the two as a basis for planning clean water infrastructure development. The methods used include calculating domestic and non-domestic water needs, plus an estimate of 30% water loss, and analyzing needs at peak hours and maximum days. The results of the analysis show that with a fixed supply capacity of 1,100 liters per second from SPAM Mebidang, the need for clean water in Medan Helvetia District until 2075 is still in a surplus condition. The highest surplus was recorded at 795.26 liters per second in 2024, and the lowest surplus was 510.77 liters per second in 2075. These findings indicate that the district is projected not to experience a clean water deficit in the long term, as long as the supply capacity remains stable and the distribution system is managed efficiently. Therefore, periodic evaluation and integrated planning are still needed to ensure the sustainability of clean water services in the future
PENGARUH BUDAYA KERJA, KOMITMEN KARYAWAN DAN MOTIVASI TERHADAP KINERJA KARYAWAN PADA CV ULTRA OUTBOND ADVENTURE
Get PDFThis study aims to analyze the influence of work culture, employee commitment, and motivation on employee performance at CV. Ultra Outbond Adventure, a company engaged in the field of education services, outbound training, and human resource development. The research employs a quantitative approach with data collected through questionnaires distributed to a total population of 73 operational employees using a saturated sampling technique. The research variables include work culture, employee commitment, and motivation as independent variables, while employee performance serves as the dependent variable. Data analysis was conducted using multiple linear regression, complemented by t-test, F-test, and coefficient of determination (R²). The results indicate that both partially and simultaneously, work culture, employee commitment, and motivation have a positive and significant effect on employee performance. Specifically, improvements in work culture, commitment, and motivation are proven to enhance employee performance levels significantly. The R Square value of 0.635 indicates that 63.5% of the variation in employee performance can be explained by these three variables, while the remaining 36.5% is influenced by other factors not examined in this study. These findings highlight the importance of strengthening organizational culture, fostering employee commitment, and enhancing motivation as strategic efforts to improve overall performance and organizational competitiveness in the service industry
