Abstract

Sampah merupakan salah satu permasalahan yang perlu dikelola, terutama jika terdapat berbagai usaha kecil menengah pada komunitas tersebut. Pengelolaan sampah di daerah Purwosekar, Kabupaten Malang, hanya mengangkut sampah dari rumah ke TPS dan diangkut ke TPA tanpa adanya pengolahan. Hal ini menyebabkan penumpukan sampah dan menganggu lingkungan sekitar. Kelompok masyarakat Sekar Mayang Desa Purwosekar, Kecamatan Tajinan, Kabupaten Malang berinisiatif untuk mengurangi masalah sampah dengan mengolah sampah organik menjadi kompos. Dalam penerapan komposting terdapat beberapa permasalahan pengetahuan dalam pembuatan kompos, belum tersedianya peralatan-peralatan tepat guna yang dapat membantu pra-pengolahan dan pemrosesan sampah dalam proses komposting, serta manajemen pemasaran produk kompos. Oleh karenanya dalam kegiatan Doktor Mengabdi ini kami akan memberikan solusi dengan penerapan teknologi tepat guna untuk membantu pengelolaan sampah dan proses komposting di daerah Purwosekar ini. Program Dokter Mengabdi dilakukan selama Bulan Juni hingga September 2021 melalui implementasi teknologi tepat guna, pelatihan pengolahan kompos, sosialisasi serta pendampingan pemasaran dalam proses pembuatan kompos kepada masyarakat. Kegiatan pengabdian masyarakat dalam menerapkan teknologi tepat guna ini memberikan manfaat dan mempermudah masyarakat Desa Purwosekar dalam pengolahan sampah organik untuk komposting.

Abstract

A tomato is classified as a fruit, which level of maturity is determined by its color. Upon distribution, tomatoes require sorting based on their ripeness level. Generally making improvements done conventionally with the human eye. This method has the disadvantage that the results are subjective. One way that can be used to measure the ripeness level of tomatoes is using a spectroscopic sensor. Spectroscopic sensors can predict the level of ripeness and its contents automatically. This study uses machine learning to create a model to classify ripeness level and predict firmness, total dissolved solids (TDS), and total acid in tomatoes. This study used tomatoes with 3 categories of maturity. Tomatoes were tested non-destructively, namely measuring firmness, total dissolved solids content, and total acid. The data obtained were processed using the Partial Least Square Regression method to predict firmness, TDS, and total acid, while the maturity level used the Naive Bayes method. The data processing results to predict the level of maturity using Naive Bayes obtained a success rate of 100%. While for the predictions of firmness, TDS, and total acid had R2 training and R2 testing, namely 0.685 and 0.678, 0.534 and 0.521, and 0.352 and 0.349, respectively.

Abstract

Aflatoxin contamination in cacao is a significant problem in terms of trade losses and health effects. This calls for the need for a non-invasive, precise, and effective detection strategy. This research contribution is to determine the best deep-learning model to classify the aflatoxin contamination level in cocoa beans based on fluorescence images and deep learning to improve performance in the classification. The process involved inoculating and incubating Aspergillus flavus (6mL/100g) to obtain aflatoxin-contaminated cocoa beans for 7 days during the incubation period. Liquid Mass Chromatography (LCMS) was used to quantify the aflatoxin in order to categorize the images into different levels including “free of aflatoxin”, “contaminated below the limit”, and “contaminated above the limit”.  300 images were acquired through a mini studio equipped with UV lamps.  The aflatoxin level was classified using several pre-trained CNN approaches which has high accuracy such as GoogLeNet, SqueezeNet, AlexNet, and ResNet50. The sensitivity analysis showed that the highest classification accuracy was found in the GoogLeNet model with optimizer: Adam and learning rate: 0.0001 by 96.42%. The model was tested using a testing dataset and obtain accuracy of 96% based on the confusion matrix. The findings indicate that combining CNN with fluorescence images improved the ability to classify the amount of aflatoxin contamination in cacao beans. This method has the potential to be more accurate and economical than the current approach, which could be adapted to reduce aflatoxin's negative effects on food safety and cacao trade losses.

Abstract

Penelitian ini menitikberatkan pada eksplorasi kemampuan spektroskopi UV/Vis/NIR untuk memprediksi parameter cupping test kualitas kopi sangrai. Sampel kopi Arabika disangrai pada suhu 198°C selama 6 menit (Light to Medium), 10 menit (Medium) dan 14 menit (Medium to Dark). Sebanyak 1 kg biji kopi disiapkan untuk tingkat waktu sangrai yang kemudian menghasilkan 20 kelompok sampel untuk menit ke-6 dan masing-masing 25 kelompok sampel pada menit ke-10 dan ke-14. Selanjutnya, dilakukan evaluasi cupping test pada kelompok sampel. Secara simultan pada kelompok sampel yang sama, dilakukan akuisisi data spektra menggunakan instrumen portable Vernier Go Direct SpectroVis Plus dan sensor MEMS (micro-electromechanical system) C12880MA. Dari hasil tersebut, menghasilkan 70 total data cupping test dan spektra yang kemudian digunakan sebagai input pembentukan model kalibrasi (prediksi). Partial Least Square Regression (PLSR) digunakan untuk membentuk model dengan Venetian blinds cross-validation 10-folds sebagai validasi internal. Hasil menunjukkan Vernier Go Direct SpectroVis Plus memiliki sensitifitas lebih baik dalam menangkap informasi yang ada pada biji kopi sangrai dan mampu memprediksi beberapa parameter cupping test yaitu Body (R2 C = 0.726, R2 CV = 0.613), Balance (R2 C = 0.738, R2 CV = 0.603) dan Overall (R2 C = 0.755, R2 CV = 0.628). Sedangkan untuk sensor MEMS C12880MA, nilai prediksi tertinggi didapat pada parameter Acidity dengan nilai R2 C dan R2 CV sebesar 0.546 dan 0.500. Berdasarkan nilai VIP Score, kontribusi terbesar dalam pembentukan model berada di rentang 760-780nm, 808-830 nm dan 843-873 nm untuk Vernier Go Direct SpectroVis Plus serta 565-637 nm dan 705-737 nm untuk MEMS C12880MA.

Abstract

AbstractPrecise recognition of potato external defects and the ability to identify defects and non-defect areas are in demand. Common scab represents a significant issue that requires detection, yet identifying the extent of common scab infection remains challenging when using a standard RGB camera. In this research, a 2CCD camera system that could obtain a set of RGB and near-infrared images, which could enhance defect detection, has been used. Image segmentation strategies based on a single principal component image and the principal component pseudo-colored image have been proposed to identify external potato defects while excluding soil deposits on the potato surface, often recognized as defects by the normal color machine vision system. Performance metrics calculation results show relatively good results, with segmentation true accuracy around 64% for both methods. Principal component pseudo-colored images were able to discriminate defects area and soil deposits in a single image. The methods presented in this paper could be used as the basis to develop further classification and grading algorithms.Keywords: image processing, multispectral, PCA, surface defects AbstrakPengenalan yang tepat terhadap cacat eksternal kentang dan kemampuan untuk mengidentifikasi area cacat dan non-cacat sangat dibutuhkan.

Abstract

Oranges (Citrus sp.) are one of the most abundant agricultural commodities in Indonesia. One of the popular local citruses is Batu Tangerine 55. Harvesting tangerines begins 252 days after the flowers bloom. Conventionally, we still determine the level of maturity by observing the color, shape, and hardness. The results of manual grouping tend to be subjective and less accurate. Destructive testing could be carried out and provide objective results; however, it would require sampling and damaging the fruits. Computer vision could be used to evaluate the maturity level of the fruit non-destructively. Dual imaging computer vision, i.e., reflectance-fluorescence mode, could be used to enhance the accuracy of the prediction. This study aims to develop a classification model and predict the physico-chemical characteristics of Batu Tangerine 55. Destructive testing is still being carried out to determine the value of TPT, the degree of acidity, and the firmness of the fruit. Non-destructive testing was carried out to obtain reflectance and fluorescence images. Once we obtain the destructive and non-destructive data, we will incorporate them into the classification and prediction models. The machine learning method for maturity classification uses three models, namely KNN, SVM, and Random Forest. The best results on the reflectance data (RGB) SVM model resulted in an accuracy of 1 for training data and 0.97 for testing data. The maturity parameter prediction method uses the PLS method. The best results for the predicted Brix/Acidity ratio R2 parameter are 0.81 and RMSE 3.4.

Abstract

The shapes of leaves distinguish the Indonesian grape variants. The grape leaves might look the same at first glance, but there are differences in leaf shapes and characteristics when observed closely. This research uses a deep learning method combined with the faster region-based convolutional neural network (R-CNN) algorithm with the Inception network architecture, ResNet V2, ResNet-152, ResNet-101, and ResNet-50, and uses COCO weights trained to classify five grape varieties through leaf images. The study collected 500 images to be used as an independent dataset. The results show that network improvements can effectively improve operating efficiency. There are also limitations to training scores because the F1 score value tends to stabilize or decrease at a certain point. In the Inception ResNet V2 architecture, with the highest average F1 score of 92%, the average computing time for training and testing is longer than other network architectures. This suggests that the algorithm can classify types of grapes based on their leaves.

Abstract

Microalgae are unicellular microscopic organisms that live in various water. Microalgae such as Spirulina platensis and Chlorella vulgaris are grown due to their potential as bioenergy source. During cultivation, typically, hemocytometers are used to manually count the cells and that is time-consuming and prone to human error. This research aims to develop microalgae detection model based on microscopic images and Convolutional Neural Network using YOLOv8 architecture. The methodology includes sample preparation (dilution and optical density measurement), best density determination, image acquisition, annotation, creation of datasets, YOLOv8 model training, and model performance evaluation. Best density determines good microscopic images. Image acquisition was done using binocular microscope and acquired 560 images which were then annotated. The YOLOv8n, YOLOv8s, and YOLOv8m models were trained using default hyperparameters on Google Collaboratory to determine the augmentation effect on model accuracy. Model performance evaluation was done on selected YOLOv8 models. The results showed the augmentation (crop, brightness, blur) get the highest mAP train and test on YOLOv8m model, which are 0.945 and 0.913. The YOLOv8m model was retrained with various hyperparameters and it was found that the best configuration was SGD optimizer, epoch 50, and learning rate 0.01 with mAP train and test are 0.934 and 0.925. However, 29 epochs yielding a better model with accuracy of 0.8535, minimising overfitting and resource wastage. This research can facilitate the more efficient and automatic counting for microalgae-related research and industry.

Prediction of sugarcane yield with bioelectric method have a potential to be developed as an easy, handy, and quick solution. However, unstandardized sample preparation techniques to measure bioelectrical of sugarcane still become a problem. This research aim is to determine measurement standard for bioelectric properties and select the most important properties for sugarcane yield prediction. Bioelectric properties (impedance, dielectric constant, and capacitance) measurement was carried out with variation of sample length and measurement frequency. Additionally, the effect of ambient temperature also considered as a correction factor. The results then was compared with the conventional method. The result recommend a preparation standard of sugarcane sample length is 3 cm with measurement frequency of 1000 Hz to measure the bioelectrical properties of sugarcane. The capacitance value correlated significantly to the yield that is recommeded as variable to develop rapid measurement of sugarcane yield.Keywords: Sugarcane, bioelectrical properties, dielectric method, rapid measurement, yield
