Abstract

Pelapisan nanokomposit dapat meningkatkan karakteristik fisik, mekanis serta fungsional dari bahan pelapis. Penelitian ini bertujuan untuk mengetahui pengaruh pelapisan nanokomposit dengan berbagai polimer (gelatin dan kitosan) yang ditambahkan seng oksida dan beeswax untuk menjaga kualitas salak pondoh selama penyimpanan. Hasilnya menunjukkan bahwa penambahan emulsi beeswax dan NP-ZnO dapat menurunkan nilai WVTR dari 25.6 menjadi 13.75 g/m2jam. Penambahahan beeswax dan NP-ZnO juga dapat merubah sifat antimikroba film kitosan dan gelatin. Aplikasi nanokomposit mampu menurunkan kehilangan berat salak pondoh selama penyimpanan dibandingkan dengan kontrol salak pondoh (P <0,05). Kontrol salak memiliki nilai penurunan susut bobot tertinggi sebesar 18,57% sedangkan salak dengan perlakuan WC3 dan WG3 memiliki nilai 12,72% dan 13,92%, persentase kerusakan  sebesar 76,19%  pada hari ke 28 penyimpanan. Aplikasi pelapisan nanokomposit juga mampu mempertahankan kekerasan dan persen tingkat kerusakan selama penyimpanan. Application of nanocomposite based on Chitosan and Gelatin to maintain quality of Salacca fruit. (Salacca edulis Reniw).Nanocomposite coating could enhance the physical and mechanical characteristic as well as functional of material coatings. This research aimed to determine the application of nanocomposite coating with various polymers (gelatin and chitosan) which added zinc oxide and beeswax to maintain the quality of salak pondoh during storage. The result showed that the addition of beeswax emulsion and ZnO-NPs significantly decreased WVTR value from  25.6 to 13.75 g/m2 hours. The addition of beeswax emulsion and ZnO-NPs also changed the antimicrobial properties of chitosan and gelatin films Aplication of nanocomposite coating was able to decrease the weight loss of salak pondoh during storage compared to salak pondoh control (P <0.05). Salak control has the largest weight loss value of 18.57% while salak with WC3 and WG3 treatment has a value of 12.72% and 13.92%, percentage of decai has value 76.19% on 28 days storage. Application of nanocomposite coating are also able to maintain quality such as firmness and percentage of decay during storage.

Abstract

Anggur merah (Vitis vinivera) adalah salah satu jenis buah yang banyak digemari masyarakat di Indonesia. Salah satu cara yang digunakan untuk menjaga mutu buah anggur merah adalah dengan pengaplikasikan bahan pelapis buah menggunakan kitosan. Penelitian ini dilakukan untuk mengetahui pengaruh pelapisan kitosan terhadap mutu buah anggur merah (Vitis vinivera). Penelitian ini dilakukan dengan variasi konsentrasi kitosan 2, 3, dan 4%. Setiap perlakuan menggunakan metode pencelupan selama 5 menit dan diamati selama 7 hari dengan waktu pengamatan hari ke 0, 3, dan 7. Hasil penelitian menunjukkan bahwa pelapisan kitosan dapat menyebabkan perubahan susut bobot dan tekstur selama penyimpanan, yang berpotensi digunakan sebagai pelapis untuk memperpanjang umur simpan anggur merah.

Abstract

Buah dan sayuran setelah dipanen akan mengalami perubahan fisikokimia akibat proses metabolisme, diantaranya adalah respirasi dan transpirasi yang mengakibatkan kehilangan air. Kehilangan air menyebabkan stres didalam jaringan sehingga laju disintegrasi membran sel meningkat. Kehilangan air yang berlebihan dapat mengakibatkan pelunakan, pengerutan dan hilangnya kecerahan pada kulit buah. Bahan pelapis berbahan kitosan dengan penambahan nanopartikel ZnO adalah salah satu alternatif bahan pelapis yang mampu menahan hilangnya air akibat proses respirasi, transpirasi serta dapat menjaga kualitas buah. Penelitian ini dilakukan untuk mengetahui pengaruh pelapisan kitosan dengan penambahan nanopartikel ZnO terhadap perubahan karakteristik buah tomat selama penyimpanan. Aplikasi pelapisan buah tomat dengan metode spray menggunakan larutan kitosan nanopartikel ZnO 3% mampu menekan kehilangan susut bobot buah tomat selama penyimpanan dibandingkan dengan buah tomat kontrol (p<0.05). Pelapisan buah tomat dengan kitosan nanopartikel ZnO 3% memiliki nilai susut bobot 4.74% pada penyimpanan hari ke 10 sedangkan buah tomat kontrol memiliki nilai susut bobot tertinggi sebesar 8.57%. Kekerasan buah tomat mengalami penurunan seiring lama penyimpanan. Nilai kekerasan buah tomat kontrol sebesar 4.23 N, sedangkan buah tomat dengan perlakuan pelapisan kitosan nanopartikel ZnO 3% memiliki nilai kekerasan 9.57 N pada hari ke 10 penyimpanan. Hasil penelitian membuktikan bahwa penambahan nanopartikel ZnO mampu menurunkan persentase susut bobot dan nilai kekerasan buah tomat selama penyimpanan.

Abstract

Tomatoes are an agricultural commodity that will experience an increase in respiration rate and ethylene production after harvesting. Ethylene in fruits will accelerate ripening, resulting in a shorter shelf life for the fruit. Chitosan-beeswax and NP-ZnO can retain the soluble solids of the fruit, inhibit respiration, and exhibit antibacterial properties, making them suitable as a coating material. This study aims to investigate the effect of chitosan-beeswax coating with the addition of ZnO nanoparticles on the quality changes of tomato fruits during storage. Coating tomato fruits with the spray method using 3% chitosan-beeswax and 3% NP-ZnO addition resulted in a weight loss value of 4.98% on the 10th day, while the control group had the highest weight loss value at 8.57%. The hardness of the control tomato fruits had the highest value at 7.72 N, whereas the 3% chitosan-beeswax treatment with 3% NP-ZnO addition exhibited a hardness of 9.64 N on the 10th day of storage. The research findings indicate that the addition of chitosan-beeswax and NP-ZnO can maintain the hardness and reduce weight loss in tomato fruits. Key Words: Coating, Chitosan, Beeswax, NP-ZnO, Storage

Abstract

Tomatoes have a short storage time and are easily damaged. Tomatoes have thin skin and high water content, so the commodity will quickly deteriorate after being treated with simulated transportation and storage processes. This research aims to analyze the effect of the simulation time on weight loss, mechanical damage, color, hardness, and total soluble solids of tomatoes and to explain the effect of simulation time treatment on weight loss, mechanical, damage, color, hardness, and total soluble solids of tomatoes during storage. This study used a completely randomized design using transportation simulation vibration times (30 minutes and 90 minutes) and controls not given vibration treatment using three repetitions and kept for 8 days. This research shows that the treatment of variations in vibration time affects mechanical damage and weight loss. Vibration time of 30 minutes on day 8 I had mechanical damage of 15,38%, weight loss of 5,77%, color L* 40,88, color a* 20,06, hardness 11,88, and total dissolved solids 4,25. Vibration time of 90 minutes has mechanical damage of 20,51%, weight loss of 7,53%, color L* 40,63, color a* 21,21, hardness 11,65 and total dissolved solids 4,33.

Abstract

Drip irrigation and self-watering are two examples of irrigation technology improvements that employ effective and efficient watering methods. Water productivity may be used as a benchmark to compare irrigation efficiency and agricultural productivity. The purpose of this study was to assess mustard green's water productivity under conventional, drip, and self-watering irrigation systems. The effect of irrigation variation on mustard green growth was studied using a nonfactorial technique with a completely randomized design (CRD). The design has three treatments and six replications. This study examined the following variables: height, number of leaves, yield, irrigation water utilized, and water productivity of mustard green. The study found that mustard green plants require 0.69 mm/day of water in the vegetative phase, 2.83 mm/day in the generative phase, and 1.69 mm/day in the final phase. The use of different watering systems has a significant influence on mustard green's height and leaf number. Self-watering at 15 g/L provides the maximum water productivity for mustard green, followed by drip irrigation at 8.46 g/L and conventional irrigation at 7.69 g/L. Keywords: Drip irrigation, Mustard green, Self-watering irrigation, Water productivity
