Abstract

Curah hujan yang tinggi di awal musim hujan sering menimbulkan genangan (kondisi jenuh air) pada pertanaman kedelai. Kondisi ini merupakan kendala bagi upaya peningkatan kedelai di lahan sawah. Penelitian bertujuan untuk menguji adaptasi dan daya hasil galur-galur harapan kedelai toleran kondisi tanah jenuh air pada berbagai sentra produksi kedelai. Sebanyak 13 galur harapan kedelai dan dua varietas yaitu Grobogan (pembanding umur genjah) dan Kawi (pembanding toleran jenuh air) diuji di empat sentra produksi kedelai, yaitu Banyuwangi, KP Jambegede, Midang (NTB) dan Sandik (NTB), pada MKI 2011. Kedelai ditanam pada kondisi jenuh air mulai umur 14 hst (fase V2) sampai fase masak, melalui penggenangan pada saluran drainase dengan cara mengatur tinggi permukaan air di dalam saluran drainase diusahakan selalu tetap pada tingkat tertentu (3-5 cm di bawah permukaan bedengan). Rancangan penelitian menggunakan Acak Kelompok, empat ulangan. Untuk menguji tingkat stabilitas dan adaptabilitas galur berdasarkan analisis AMMI (Additive Main Effects and Multiplicative Interaction) yang digambarkan oleh grafik biplot AMMI melalui IPCA (interaction principal component axes), galur yang berada dekat dengan titik nol (0,0) dinilai stabil. Interaksi galur dengan lingkungan  nyata untuk hasil biji dan komponen hasil. Dari uji adaptasi di empat lokasi diperoleh dua galur yang secara konsisten mampu memberikan hasil terbaik pada kondisi jenuh air yaitu Galur Tgm/Anjs-T205-1-750 dan Sib/Grob-V64-5-137. Galur Tgm/Anjs-T205-1-750 memiliki potensi hasil 2,63 t/ha, berumur genjah (78 hari), dan berukuran biji sedang (12,3 g/100 biji). Galur Sib/Grob-V64-5-137 memiliki potensi hasil 2,71 t/ha, berumur genjah (79 hari), dan berukuran biji besar (14,5 g/100 biji). Berdasarkan metode AMMI, galur Tgm/Anjs-T205-1-750 dan Sib/Grob-V64-5-137 dinilai stabil dan berpeluang dikembangkan di berbagai sentra produksi kedelai, terutama pada kondisi tanah jenuh air.

Abstract

Infused water is a functional beverage made by soaking slices of fruits, vegetables, and herbs in mineral water to produce a natural flavor and enhance nutritional content. In recent years, infused water has become part of a healthy lifestyle trend due to its claimed benefits, including detoxification, improved hydration, and immune system enhancement. This article aims to review the latest scientific literature on the potential benefits of infused water on immune function, particularly in the context of regular consumption of natural ingredients such as lemon, ginger, strawberries, and herbs that are rich in vitamin C, antioxidants, and flavonoids. The review was conducted by searching scientific databases such as PubMed, Google Scholar, and ScienceDirect, using inclusion criteria that covered publications from 2020 to 2024. The findings indicate that infused water containing vitamin C, gingerol, and polyphenolic compounds can help improve immune function by reducing oxidative stress, suppressing inflammatory responses, and stimulating immune cell activity such as lymphocytes and macrophages. Furthermore, optimal hydration from infused water supports various physiological processes of the immune system. In conclusion, infused water holds potential as a simple, natural, and cost-effective strategy to support immune health. However, further research is needed to evaluate its efficacy, optimal formulations, and dosage for maximum benefit.

Abstract

APPLICATION OF RIETVELD ANALYSIS TO THE MULTIPHASE CRYSTAL STRUCTURE Bi1/2K1/2TiO3 USING MOLTEN SALT SYNTHESIS. Recently, an interesting application development of piezoelectric materials is as part of the tool for in-situ testing of nuclear fuel and the supporting materials in nuclear reactor, as well as sensors for safety systems in the reactor environment itself. One of the piezoelectric materials (lead free) is bismuth potassium titanate Bi1/2K1/2TiO3 (BKT) which is used in this research and has been successfully synthesized using the molten salt method. This method is a simple process that reacts to the base material in a solution of NaCl and KCl salts to produce nanocrystal ceramics powder with good compositional homogeneity and sinterability. The synthesis process has been carried out in two stages, first to produce Bi2Ti4O11 and then to add excess K2CO3 as a base material to produce BKT. The weight ratio between Bi2Ti4O11 and excess K2CO3 was 1:1.5 and 1:2. Structural identification of the synthesized results has been done by Rietveld analysis of the XRD pattern using PAN-Analytical Highscore software. The multiphase of BKT has been obtained by a predominantly tetragonal crystal system, in addition to cubic as second phase. This is indicated by the content of the tetragonal and cubic phases obtained at 64.5 and 36.5% for the ratio 1:1.5 and 80.3 % and 19.7 % for the ratio 1:2, respectively.The addition of excess K2CO3 increases, the content of the tetragonal BKT phase increases. . Besides that, the “a” lattice parameter increases and the “b” lattice parameter decreases, if the K2CO3 content is added. Likewise, the size of the crystallite and microstrain decreases with the in excess K2CO3.
