Abstract

Melon productivity in Indonesia has been declining. Global climate change is affecting the productivity of melons. Long-term droughts have contributed to a reduction in plant growth and development. Hormopriming is an alternative to increase the germination and growth of melon plants by soaking seeds in a solution of plant growth regulators. Brassinosteroid can enhance germination and plant tolerance under drought conditions. The objective of this research is to examine the impact of brassinosteroid hormopriming treatment on the germination and growth of melon plants subjected to various degrees of drought stress. The study utilized a two-factor fully randomized design. The brassinosteroid concentrations used were 0, 0.05, 0.10, and 0.15 ppm. Media with different water capacities of 75%, 50%, and 25% Space Capacity (SC) were used to test drought stress resistance. Water capacities were examined using the gravimetric method. This study's findings suggest that treating melon plants with brassinosteroid variations can induce drought resistance in M15 melons. A brassinosteroid concentration of 0.15 ppm is the best concentration, as it can increase all parameters of plant growth and adaptation under each variation of water availability provided. The findings of this study can serve as a reference for melon cultivators constrained by dry land conditions to increase the efficiency of cultivation.

Abstract

Potato (Solanum tuberosum L.) plant is widely favored due to its versatility in various processed products, but perishable. This study aimed to determine the effect of chitosan coating and storage at various temperatures on the physiological and chemical characteristics of potato tubers. This research used 2 variables, namely the concentration of chitosan (0, 1, 1.5 and 2%) and storage temperatures of 0, 10 and 25°C. The parameters observed included tuber skin color, weight loss, hardness, the thickness of the chitosan layer and tissue penetration, oxygen levels, water content, starch degradation, reduced sugar content, and sprouting amount. Furthermore, data were analyzed using the Analysis of Variance (ANOVA) test. The results showed the effect of chitosan coating and storage temperature on weight loss, color, oxygen level, hardness, water content, starch degradation, and reduced sugar content in potato tubers during storage. The most effective treatment was 1.5% chitosan coating combined with a storage temperature of 10°C.

Abstract

Penelitian ini bertujuan untuk menguji pengaruh variabel independen yakni perdamaian, keadilan dan lembaga yang tangguh terhadap pertahanan nasional untuk menghadapi bonus demografi yang puncaknya akan terjadi pada tahun 2030. Variabel perdamaian diproyeksikan oleh jumlah kejahatan yang ada di Indonesia, variable keadilan diproyeksikan oleh indeks demokrasi, Lembaga yang tangguh diproyeksikan dengan tingkat Persentase Kepatuhan pelaksanaan UU Pelayanan Publik dan variable dependen Pertahanan Nasional diproyeksikan oleh persentase anggaran sektor pertahanan. Penelitian yang digunakan adalah penelitian deskriptif kuantitatif. Data yang digunakan diperoleh dari Badan Pusat Statistik Indonesia dengan jangka waktu data 2015-2020. Penelitian menggunakan metode analisis regresi linear berganda dengan IBM SPSS 25. Hasil penelitian menunjukan bahwa secara perdamaian dan keadilan berpengaruh secara positif dan signifikan terhadap pertahanan nasional sedangkan lembaga yang tangguh tidak berpengaruh pada pertahanan nasional.

Abstract. Rahmawati NA, Solichatun, Pitoyo A. 2026. Effects of TiO₂ nano-priming and field capacity levels on germination and growth of cayenne pepper (Capsicum frutescens). Asian J Agric 10 (1): g100112. https://doi.org/10.13057/asianjagric/g100112. Capsicum frutescens is a vital crop in Indonesia but suffers from seasonal yield instability due to water stress. This study explored nano-priming with titanium dioxide nanoparticles (TiO₂NPs) to improve seedling resilience. The experiment was conducted in two stages. In the germination stage, four TiO₂NP concentrations (0%, 2%, 4%, and 8%) were tested on seed germination using a Completely Randomized Design (CRD). In the growth stage, seedlings were subjected to a 4 × 3 factorial CRD combining the same TiO₂NP concentrations with three levels of water availability (100%, 75%, and 50% field capacity), with three replicated. Data were analyzed using two-way ANOVA and Duncan’s Multiple Range Test (p < 0.05). During germination, nano-priming with 4% TiO₂NP accelareted germination rate (5.3 days) and enhanced sprout length (6.68 cm), whereas the control exhibited slower germination (9.03 days) and shorter sprouts (2.60 cm). In the subsequent growth phase, TiO₂NPs significantly influenced seedling height, shoot-to-root ratio, and proline content. The tallest seedling was observed at 8% TiO₂NP, particularly under 75% field capacity. In contrast, optimal shoot-to-root ratio and elevated proline accumulation were associated with 2% TiO₂NP under 100% and 75% field capacity, respectively. These finding demonstrated that TiO2NP nano-priming exerts stage-dependent effects, with distinct concentrations optimizing germination performance and drought-related physiological responses during early seedling growth, highlighting its potential as a scalable approach for improving C. frutescens cultivation under water-limited conditions.
