Abstract

Tomato (Lycopersicon esculentum Mill.) is a horticultural plant with high economic value, consumed as fresh fruit or a processed product. However, this plant still requires serious handling, especially in tomato seeds. The seeds are coated with quite slimy flesh and need to be separated using a suitable method so that the flesh layer can be cleaned optimally. Tomato seeds have a high water content, causing the seeds to easily damaged and quickly decrease their viability. Therefore, it is necessary to dry the seeds properly to lower the water content while maintaining the seed’s quality. This research aimed to calculate the time needed to reduce the water content of tomato seeds in a dehumidified drying machine, analyze the germination percentage of tomato seeds resulting from dehumidified drying using various separation techniques, and measure the effect of separation techniques. The temperature of dehumidified drying affects the germination and vigor of tomato seeds. The experiment was carried out using a two factorial Completely Randomized Design (CRD) method, namely separation technique (i.e., left for 24 hours, using 2% HCl, and using 10% Na2CO3) and temperature in a dehumidified drying machine (i.e., 30, 40, 50, and 60 °C). The highest germination percentage and vigor index were produced in the treatment with 2% HCl for 2 hours with a drying temperature of 40°C. The separation technique and drying temperature influenced the germination percentage and vigor index, but the interaction between separation techniques had no effect.

Abstract

Sebagian besar masyarakat Desa Ngawonggo Kabupaten Malang bekerja disektor pertanian dan peternakan. Peternakan yang dikembangkan adalah peternakan ayam (25 usaha) dan perikanan (20 usaha kolam ikan lele). Permasalahan utama dalam usaha peternakan dan perikanan ini adalah pakan, karena biaya pakan bisa mencapai 75% produksi, harga pakan sangat berfluktuasi,  pakan harus diimpor. Permasalahan lain dari pakan adalah ketersediaannya yang tidak pasti di pasaran. Tujuan dari kegiatan Doktor Mengabdi ini adalah mendesimasi teknologi pengolahan pakan ayam dan lele dengan memanfaatkan bahan baku lokal di UKM Forum Nusantara Mandiri Desa Ngawonggo Kecamatan Tajinan Kabupaten Malang. Kegiatan ini meliputi implementasi mesin produksi pakan, pembimbingan teknis, pendampingan pemasaran dan evaluasi/ monitoring. Hasil kegiatan mesin bisa berproduksi dalam pembuatan pelet ikan dan ayam, anggota kelompok sudah bisa menerapkan pemasaran secara online. Kegiatan Doktor Mengabdi ini dapat memecahkan permasalah pakan ayam dan lele melalui pengoptimalan sumber daya lokal sehingga bisa meningkatkan pendapatan petani/peternak.

Abstract

Jamur kancing merupakan komoditas hasil pertanian yang mudah rusak sehingga harus segera ditangani setelah panen. Salah satu cara untuk mengawetkan jamur kancing adalah melalui proses pengeringan vakum. Pengeringan vakum bekerja dengan menguapkan air pada tekanan rendah sehingga titik uap air tercapai pada suhu rendah dengan waktu yang lebih singkat. Kombinasi blanching dan dehidrasi osmotik diharapkan dapat mencegah proses pencoklatan pada jamur kancing. Tujuan penelitian ini adalah menganalisa perubahan warna jamur kancing selama proses pengeringan vakum dengan pra-perlakuan blanching dan dehidrasi osmosis dengan penambahan asam askorbat serta menentukan pemodelan perubahan warnanya. Dalam penelitian ini, dilakukan konversi atribut warna pada image perubahan warna jamur kancing selama pengeringan vakum pada suhu 35, 45 dan 55 °C dengan kombinasi pra-perlakuan blanching dan dehidrasi osmosis. Delapan model matematika empiris perubahan warna digunakan untuk menentukan model terbaik. Hasil penelitian menunjukkan bahwa pengeringan pada suhu 35 °C mampu menghambat pencoklatan jamur kancing yang tampak dari nilai atribut warna L*, a*, b* dan ( . Model NIST Hahn 1 dan Power merupakan model terbaik yang mampu menjelaskan perilaku perubahan warna pada pengeringan vakum jamur kancing berdasarkan uji ketepatan R², RMSE, dan nilai X².

Abstract

Cocoa plant is widely cultivated in Indonesia and spread across various regions. Diversity in geographical conditions has been known to significantly affect the quality of cocoa beans. Practically, cocoa beans are often mixed without considering the variation in the quality and its origin. This resulted in reduced global quality and product inconsistency. Improved recognition and classification methods are needed to solve those problems. Non-destructive classification methods can be used to provide a more efficient classification process. The use of artificial intelligence with computer-based deep learning methods was used in this study. Beans samples of various origins (Aceh, Bali, Banten, Yogyakarta, East Kalimantan, West Sulawesi, and West Sumatera) were evaluated. From thecollected samples, 9100 images were then taken for data processing. Data preprocessing included denoising of the background image, cropping, resizing andchanging the storage extension through the training-validation stage and the testing process. AlexNet and ResNet architectures on a Convolutional NeuralNetwork were used for classification. The results showed that the average accuracy of cocoa image classification based on color identification by computer machines using Alexnet and ResNet was high (99.91% and 99.99%, respectively). This method can be applied to provide more efficient color-based cocoa bean classification for industrial purposes.

Abstract

One strategy to increase peanut production is to use good-quality seeds. The content of the seed determines the quality of the seed. Drying with low relative humidity can lower the drying temperature so that drying is done quickly and seed quality is maintained. This research was conducted to analyze the process and differences in peanut seed drying using dehumidifier drying and oven drying methods. Drying was carried out using a dehumidifier and oven drying machine at 30 °C, 40 °C, and 50 °C until the moisture content reached 9%, with observations every 30 minutes. Then the dried seeds were analyzed for their physical and physiological qualities. The results showed that the time needed for dehumidifier drying was faster than oven drying, with the details of dehumidifier machine drying at 30 °C, 40 °C, and 50 °C being 18.5 hours, 15 hours, and 10.5 hours. While drying in the oven at the same temperature, it takes 21 h, 17 h, and 12 h. From the results of the analysis of the physical quality of the seeds, the germination test, and the vigor test, it can be seen that dehumidifier drying gave the highest seed percentage results of 98%, 98%, and 88%. Keywords: Dehumidifier, Drying, Peanuts, Seed Quality, Water content.

Abstract

Honey has significant health benefits due to its rich content of nutrients, enzymes, and bioactive compounds. However, conventional processing methods such as pasteurization can potentially degrade the physical and chemical quality of honey, including moisture content, density, total soluble solids, viscosity, and color stability. This study examines the effectiveness of the Evaporator Vacuum Cooling Four in One technology in maintaining the quality of Acacia honey compared to various pasteurization durations. The results show that vacuum cooling technology significantly preserves honey quality in terms of moisture content, density, and total soluble solids at a better level than conventional methods. Additionally, vacuum cooling optimally maintains honey's viscosity and color, demonstrating its superiority in reducing damage to bioactive components. This study is expected to contribute to the development of more efficient honey processing technology in the industry, aiming to provide high-quality honey that meets consumer health standards.

Abstract

The application of grass chopper technology in the livestock sector plays an important role in increasing the efficiency of feed provision, particularly for goat farms. This study aims to analyze the effectiveness of the use of grass chopper machines in accelerating the availability of feed and its impact on the productivity of goat farms. The methods used included observation and direct interviews with farmers who applied this technology. The results of the study showed that the grass chopper machine was able to shorten feed preparation time by up to 50% so that farmers could provide sufficient and quality feed in a shorter time. The machine capacity is 200 kg/h, with an average chopped size of approximately 3-4 cm. Consistent chopping can increase feed digestibility, which contributes to increased body weight and livestock health.
