Pengaruh Lama Perendaman dan Suhu Penyimpanan pada Penanganan Cabai Merah (Capsicum annum L.) Menggunakan Sistem Ozonisasi
No full textAbstrak. Cabai merah (Capsicum annuum L.) merupakan tanaman pertanian yang strategis untuk dibudidayakan karena permintaan cabai yang sangat besar dan banyak konsumen yang mengkonsumsi cabai. Cabai merah memiliki umur simpan yang relatif pendek dan memiliki sifat yang mudah rusak. Kerusakan tersebut dipengaruhi oleh kadar air yang sangat tinggi yaitu 90 % dari kandungan cabai merah itu sendiri. Metode ozon mampu meluruhkan kontaminasi pestisida dan bakteri serta logam berat yang menempel pada buah/sayur sehingga aman dikonsumsi bagi kesehatan. Lama perendaman ozonisasi 10 menit, 15 menit dan 20 menit berpengaruh nyata terhadap susut bobot, dan uji sensori yaitu warna dan tekstur, tetapi tidak berpengaruh nyata terhadap vitamin C. Dari hasil penelitian susut bobot terendah terdapat pada perlakuan tanpa perendaman ozon yaitu 43,70 % dengan 10 oC, volume iodin tertinggi terdapat pada perlakuan perendaman ozon 20 menit pada suhu 10 oC yaitu 0,50 ml, nilai sensori warna dan tekstur pada perlakuan perendaman ozon 20 menit lebih disukai daripada perlakuan perendaman ozon lainnya dengan suhu 10 oC. Dari hasil penelitian penyimpanan cabai merah dengan perlakuan yang terbaik adalah penyimpanan suhu 10 oC dengan perlakuan perendaman ozon 20 menit dengan susut bobot 49,27 %, vitamin C 0,43 ml iodin, nilai sensori warna 3,68 dan nilai sensori tekstur 3,36.The Effect Of Soaking Duration In Ozonization System And Storage TemperatureOn The Quality And Shelf Life Of Red Chili (Capsicum annum L.)Abstract. Red chili (Capsicum annuum L.) is a strategic agricultural crop for cultivation because the demand for chili is very large and many consumers consume chili. Red chilies have a relatively short shelf life and are easily damaged. The damage is affected by a very high water content, which is 90% of the content of the red chili itself. The ozone method is able to dissolve pesticide and bacterial contamination as well as heavy metals attached to fruits/vegetables so that they are safe for health consumption. Ozonization immersion time of 10 minutes, 15 minutes and 20 minutes had a significant effect on weight loss, and sensory tests, namely color and texture, but had no significant effect on vitamin C. From the results of the research, the lowest weight loss was found in the treatment without ozone immersion, namely 43.70%. with 10 oC, the highest volume of iodine was found in the 20 minute ozone immersion treatment at 10 oC, namely 0.50 ml, the color and texture sensory values in the 20 minute ozone immersion treatment were preferred over other ozone immersion treatments with a temperature of 10 oC. From the results of research on red chili storage with the best treatment is storage at 10 oC temperature with ozone immersion treatment for 20 minutes with a weight loss of 49.27%, vitamin C 0.43 ml of iodine, color sensory value 3.68 and texture sensory value 3.36

Jeruk nipis kering berpotensi digunakan sebagai bahan alternatif dalam pembuatan infused water yang lebih aman dibandingkan jeruk nipis segar karena masa simpannya lebih panjang dan risiko pertumbuhan mikroorganismenya lebih rendah. Pengeringan turut berperan mempertahankan kualitas serta nilai gizi, sehingga produk tetap bermanfaat saat dikonsumsi. Penelitian ini bertujuan mengevaluasi pengaruh variasi suhu pengeringan terhadap mutu irisan jeruk nipis sekaligus menganalisis aspek biaya prosesnya. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima taraf suhu, yaitu 40C, 50C, 60C, 70C, dan 80C. Parameter mutu yang diamati meliputi kadar air, laju pengeringan, dan kadar vitamin C. Analisis ekonomi mencakup biaya tetap, biaya variabel, biaya total, biaya pokok pengeringan, dan rasio B/C. Hasil penelitian menunjukkan bahwa suhu pengeringan tidak berpengaruh nyata terhadap kadar air akhir, tetapi berpengaruh signifikan terhadap kadar vitamin C. Suhu 80C menghasilkan laju pengeringan tertinggi dengan waktu tercepat (420 menit), namun menurunkan kadar vitamin C lebih besar. Sebaliknya, pengeringan pada 40C mampu mempertahankan kadar vitamin C lebih tinggi, meskipun membutuhkan waktu lebih lama (25 jam). Analisis ekonomi menunjukkan nilai rasio B/C1, yang mengindikasikan bahwa proses pengeringan jeruk nipis kering layak secara finansial dan berpotensi untuk dikembangkan pada skala agroindustri kecil hingga menengah.The Effect of Temperature Variation on the Quality and Cost of Drying Lime Slices (Citrus aurantifolia Swingle)Abstract. Dried lime has the potential to be used as an alternative ingredient in the preparation of infused water, offering greater safety compared to fresh lime due to its longer shelf life and lower risk of microbial growth. The drying process also plays an important role in maintaining the quality and nutritional value of lime, ensuring that it remains beneficial for consumption. This study aimed to evaluate the effect of different drying temperatures on the quality of lime slices as well as to analyze the economic aspects of the drying process. The experiment was arranged using a Completely Randomized Design (CRD) with five levels of drying temperature: 40C, 50C, 60C, 70C, and 80C. The quality parameters observed included moisture content, drying rate, and vitamin C content. The economic analysis covered fixed costs, variable costs, total costs, unit cost of drying, and the B/C ratio. The results showed that drying temperature had no significant effect on the final moisture content but significantly affected the vitamin C content. Drying at 80C produced the highest drying rate with the shortest processing time (420 minutes) but resulted in a greater reduction of vitamin C. Conversely, drying at 40C retained higher vitamin C content, although it required a longer drying time (25 hours). The economic analysis indicated a B/C ratio greater than 1, demonstrating that the lime drying process is financially feasible and has the potential to be developed on a small- to medium-scale agroindustry

This study examined the potential of starch extracted from kluwih seeds (Artocarpus camansi) as a base material for producing environmentally friendly edible films. Glycerol was added at varying concentrations to act as a plasticizer, aiming to produce edible films with both tensile strength and elasticity. The variation in glycerol concentration had a significant impact on the physical and mechanical properties of the resulting edible films. Increasing the glycerol content from 1% to 1.3% tended to reduce tensile strength but increased elongation, indicating enhanced film flexibility. Additionally, the thickness and swelling rate of the edible films also increased with higher glycerol content, while the Water Vapour Permeability (WVP) values also rose, suggesting higher water vapour permeability. The tensile strength ranged from 79.80 to 110.10 MPa, elongation from 6.71% to 9.13%, film thickness from 0.1225 to 0.1625 mm, and swelling values between 270.95% and 302.60%. The WVP ranged from 4.69 10 to 7.98 10 g.m/m.s.Pa. Thermal analysis also indicated relatively low thermal resistance of the films
