Abstract

Sari. Zukini merupakan sayuran buah yang banyak diminati oleh konsumen. Sayuran ini memiliki kadar air yang tinggi. Petani memerlukan teknik budidaya yang tepat untuk meningkatkan kualitas buah zukini, diantaranya dengan penggunaan hormon giberelin (GA3) dan waktu panen yang tepat. Tujuan dari penelitian ini adalah untuk mengetahui efek penggunaan GA3 dan perbedaan waktu panen terhadap kualitas hasil buah zukini, yaitu nilai total padatan terlarut (TPT), kekerasan, dan kadar air buah. Penelitian menggunakan metode percobaan rancangan acak lengkap (RAL) factorial, dengan 2 faktor dan 5 ulangan. Faktor pertama yaitu konsentrasi GA3 (0 part per million (ppm) dan 300 ppm) dan faktor kedua yaitu waktu panen 5 hari setelah berbunga (HSB), 10 HSB, dan 15 HSB. Data diuji dengan analisis sidik ragam (ANOVA), dilanjutkan uji lanjut Duncan dengan taraf nyata 5% dan diolah menggunakan software SPSS 24. Hasil penelitian menunjukkan bahwa terdapat interaksi antara GA3 dan waktu panen terhadap kadar air buah zukini. Konsentrasi GA3 300 ppmmenghasilkan kulit buah yang lebih keras dibandingkan dengan GA3 0 ppm kemudian 10 HSB dan 15 HSB memiliki nilai kekerasan lebih keras dibandingkan 0 HSB. Nilai TPT untuk GA3 300 ppm dan GA3 0 ppm menghasilkan nilai yang sama, sedangkan 5 HSB dan 10 HSB menampilkan nilai TPT lebih tinggi ketimbang 15 HSB. Kata Kunci: Cucurbitaceae ∙ hormon ∙ kadar air ∙ kekerasan buah ∙ total padatan terlarut  Abstract.  Zucchini is a fruit vegetable that is a lot of demand by costumers. This vegetable has a high water content. The farmers needs proper cultivation techniques to improve the quality of zucchini, including the used of the hormone gibberelin (GA3) and the harvest periods. The aim this research was to know effect used GA3 and harvest periods toward zucchini fruit quality, that were total soluble solids (TDS), firmness and fruit water content. This study used a Completely Randomized Design (CRD) with factorial pattern with 2 factors and 5 replications. The first factors was concentration of  GA3  (0 part per million (ppm) and 300 ppm) and the second factor was harvest periods (5 days after flowering (DAF), 10 DAF, and 15 DAF). Data were tested by analysis of variance (ANOVA), followed by Duncan Multiple Range test with a significance level of 5% and processed using SPSS 24 software. The results of the study showed that there were interactions between GA3 and harvest periods on moisture content of zucchini fruit. Concentration of GA3 300 ppm obtained fruit skin that is harder than GA3 0 ppm and 10 DAF, then 15 DAF have a harder firmness values than 0 DAF. TDS values for GA3 300 ppm and GA3 0 ppm presented the same value, then 5 DAF and 10 DAF showed TDS value higher than 15 DAF.  Keywords: Cucurbitaceae ∙ fruit firmness ∙ hormone ∙ water content ∙ total soluble solids

Abstract

Red chili is an important commodity that is daily needed by the community. Non-central chili areas often experience deficits due to the high consumption volume and low productivity of chili peppers. To increase the productivity of chili in non-central areas, expand it in the medium land. This study aims to determine the productivity of two introduced chili varieties in the medium land whose adaptation areas came from lowland and highland areas. This study was analyzed using an independent sample T-test at a significant level of 5%. The results of the data analysis showed that the Tanjung II variety significantly influenced the parameters of stem diameter and weight of the fruit. Meanwhile, the Unpad CB2 variety significantly influences the parameters of plant height, number of leaves, number of flowers, number of fruits, and fruit set. However, both varieties have no noticeable effect on the weight parameters of the cropping fruit and potential yield in hectares. The Tanjung II variety experienced a decrease in yield by 54.58%, while the Unpad CB2 variety was 53.56%.

Abstract

The fruit sweetness is the main target in melon plant production. The highest criterion of sweetness is excellent, with 16% of total sugar content. Modification of essential plant nutrients is the alternative to reach that category. So, this study aims to obtain optimum NPK doses using a simple regression method. The experiment was conducted in a greenhouse with a soilless culture hydroponic system from August until November 2023 using a completely randomized design (CRD) with five treatments and four replications. The parameters included leaf area, plant dry matter, leaf nutrient uptake, fruit weight, and fruit sugar content. Pearson correlation analysis showed that the total sugar content in fruit has a significantly positive correlation with potassium in NPK fertilizer treatments such as K2O dose and K2O uptake at 7 WAP, i.e., 0.932 and 0.973, respectively. According to the regression model y = -50.7 + 1.079 N + 0.251 P2O5 + 0.528 K2O, the NPK formula fertilizer containing 31.56 g N, 23.99 g P2O5, and 50.42 g K2O can be used by grower to produce excellent fruit sugar content.

Abstract

Wood ear mushrooms are often consumed in Asia and Tropical America for their jelly-like texture, health, and freshness. However, they are easily damaged due to microbes and poor postharvest handling, which affects quality. The combination of nano edible coating, packaging, and storage temperature offers a solution to these issues. This study aims to evaluate the effect of nano edible coating, packaging, and storage temperature on the color (L*, a*, and b*), water content, and antioxidant properties (total phenolic and flavonoid) of wood ear mushrooms. The study was conducted at the Horticulture Laboratory, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was a Completely Randomized Design with a total of 18 combinations of nano edible coating (sodium alginate and aloe vera), packaging (biodegradable, wrap, and vacuum plastic), and storage temperature (±25 ℃, 10 ℃, and 5 ℃). Each treatment was replicated twice, resulting in 36 experimental units, with 3 mushrooms per unit for a total of 108 mushrooms. The results showed a significant effect of the combination treatments on L* at 9 days after treatment (DAT), a* at 6 DAT, water content at 6 and 9 DAT, total phenolics, and total flavonoids during the storage period. Nano aloe vera with vacuum packaging at 5 ℃ gave the best effect on L* value at 9 DAT, water content at 6 and 9 DAT, total phenolic at 3 and 6 DAT, and total flavonoid at 6 DAT. These results indicated the potential of the treatment in maintaining the quality of the wood ear mushroom during storage.

Abstract

Climate change, with global temperatures rising by 1.09°C from 1850–1900 to 2011–2020, threatens potato production, a critical staple crop, by exceeding the optimal temperature range of 15–20°C. This review synthesizes over 45 peer-reviewed studies published between 2015 and 2025 from Google Scholar and ScienceDirect to evaluate the physiological, morphological, and tuber quality responses of potatoes to high temperatures and to identify adaptive cultivation strategies for sustainable production. High temperatures reduce photosynthetic efficiency through chlorophyll degradation and stomatal closure, increase respiration, and divert photosynthates to vegetative growth, leading to 18–32% yield losses globally by the 2050s. Heat-tolerant varieties, such as Atlantic (11.47 tons/ha), Merbabu-17 (11.04 tons/ha), and Granola (3.61 tons/ha), maintain productivity in medium-altitude lands. Plant growth regulators (PGRs), including BAP, melatonin, and paclobutrazol, enhance tuber yield by regulating hormonal balance and antioxidant activity. Drip irrigation and mulching (e.g., straw, wheat, plastic films) improve water use efficiency and buffer soil temperature. These integrated strategies of heat-tolerant varieties, PGRs, irrigation, and mulching offer practical solutions to mitigate heat stress and ensure sustainable potato production under changing climate conditions.
