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.
