Abstract

Identifikasi buah tropis berbasis citra digital menghadapi tantangan multidimensi akibat keragaman morfologi intra-kelas (seperti variasi tingkat kematangan pada pisang) dan kesamaan visual antar-kelas (misalnya kemiripan geometris antara mangga dan nanas), diperparah oleh kondisi lingkungan lapangan yang tidak terkontrol seperti pencahayaan dinamis dan latar belakang kompleks. Untuk mengatasi masalah ini, penelitian ini mengusulkan strategi adaptasi spesifik domain pada arsitektur EfficientNetB0 melalui integrasi blok lapisan kustom yang terdiri dari Dense Layer 256-neuron dengan aktivasi swish, normalisasi lapisan (Layer Normalization), dan Spatial Dropout 0.3, serta mekanisme kalibrasi bertahap (gradual unfreezing) yang membuka lapisan konvolusional secara progresif. Dataset sebanyak 5.200 citra buah tropis Indonesia (pisang, mangga, nanas, durian, rambutan) diperkuat dengan teknik augmentasi dinamis berbasis domain knowledge, termasuk color jitter terarah dan random erasing untuk meniru variasi kondisi riil. Hasil eksperimen menunjukkan pencapaian akurasi validasi 88.7% dan F1-score rata-rata 0.87, yang mengungguli kinerja MobileNetV2 sebesar 6.4% dalam uji komparatif. Implementasi operasional dalam sistem FruitScan-ID membuktikan efektivitas metode ini dengan mengurangi kesalahan identifikasi manual hingga 40%, menawarkan solusi komputasi tepi (edge-computing) yang hemat sumber daya untuk otomasi industri pertanian tropis.

Abstract

Assessing public satisfaction is crucial for evaluating the quality of services provided by government agencies. The purpose of this study was to analyze public satisfaction with the services provided by the Bunga Pasang Salido Village Head Office. This study used the K-Means algorithm, a clustering technique commonly used in data analysis, to categorize respondents' satisfaction levels. This algorithm effectively categorizes respondents into categories such as dissatisfied, satisfied, and very satisfied based on their responses in a satisfaction survey. The dataset used in this study was derived from questionnaires completed by 61 respondents who interacted with the population administration service. The questionnaire data covered various aspects of service quality, including service process efficiency, officer attitudes, and overall user experience. The results of the clustering analysis showed that 27.87% of respondents were dissatisfied, 42.62% were satisfied, and 29.51% were very satisfied with the services provided. This classification provides valuable insights into areas for improvement and helps the Bunga Pasang Salido Village Head Office improve service quality. This study highlights the importance of using data-driven methods, such as the K-Means algorithm, in improving public sector performance and overall service quality.

Abstract

Jamu is a traditional medicine made from natural cultural heritage that has been passed down from generation to generation for health. Mbak Sum UKM is a small and medium enterprise that operates in the field of medicines, namely herbal medicine, where this business provides various types of herbal medicine. This herbal medicine business is a business that can promise business opportunities. Because there is so much interest in this natural herbal concoction, it makes it difficult for companies to meet product availability. And this makes SMEs need many suppliers to meet product availability for Mbak Sum's SMEs. Therefore, a system is needed to help Mbak Sum's SMEs overcome the problems they face. The system that will help Mbak Sum's UKM is a decision support system in selecting quality suppliers which will later help in fulfilling herbal herbal products in Mbak Sum's UKM as well as in making reports of incoming products from suppliers to Mbak Sum's UKM. The system built to support supplier selection decisions uses the multi-objective optimization by ratio analysis (MOORA) method. The MOORA (Multi-Objective Optimization On The Basis Of Ratio Analysis) method is a multi-objective optimization technique that can be successfully applied to solve various types of complex decision-making problems in decision making. The results obtained were that the first rank was Alternative 3 with a value of 0.284 and the sixth rank was Alternative 6 with a value of 0.164. The calculation process can be concluded that A3 is the best alternative

Abstract

Malnutrition in toddlers causes a negative impact on motor nerve development, inhibits behavioral and cognitive development causing a decrease in academic performance and social skills . In addition, malnutrition during infancy can cause long-term risks that focus on later in life, increasing the risk of disease or disability or even death. With advances in information technology today, it is very helpful in predicting or identifying an event, one of which is an expert system that can help an expert in identifying a disease in the world of medicine. Therefore, an expert system is needed that can help doctors and the public find out the type of malnutrition they are suffering from based on the symptoms they are experiencing. The expert system uses the Certainty Factor method in reasoning to obtain diagnostic results from the symptoms shown. This method uses the value of an expert's belief in the symptoms of a disease. The aim of this research is to apply the certainty factor method in identifying malnutrition and providing definitions and suggestions for the disease suffered. The expert system was built using PHP and MySQL database. The results of applying the Certainty Factor method based on the tested data showed that the disease suffered by the patient was Kwarshiorkor with a Certainty Factor level of 0.958528 or 95%. The results of this test show that the certainty factor method expert system is able to identify a disease based on the symptoms experienced
