Abstract

Methamphetamine or N-methyl-alpha-methyl phenethyl amine is a powerful central nervous system stimulant drug that has an addictive effect when consumed. The number of cases of drug abuse in Indonesia in the last year is most dominated by methamphetamine so that an accurate analysis is needed to detect these compounds. Qualitative rapid detection can be done with marquis reagents which will produce a yellowish green if it is positive for consuming methamphetamine. Student urine samples were extracted with chloroform to separate to form two layers. The top layer filtrate was tested by Marquis reagents. From the test results found no positive Methamphentamine in the urine of class XI IPA students.

Abstract

This study aimed to formulate and evaluate an NPK compound fertilizer with a target ratio of 10:6:20 to enhance green mustard (Brassica juncea) productivity. At CV Tabita Jaya, standardized production methods were used to prepare the fertilizer by mixing Urea, triple superphosphate, and potassium chloride, with analytical confirmation of the nutrient content. Results showed nitrogen (N) content of 10.8%, phosphorus (P₂O₅) at 6.5%, and potassium (K₂O) at 20.8%, closely aligning with the target formulation. Moisture content was low at 2.48%, ensuring product stability and ease of application. Analytical techniques employed included Kjeldahl titrimetry for nitrogen, molybdate-vanadate spectrophotometry for phosphorus, and flame photometry for potassium. These methods demonstrated high reliability, with parameters such as repeatability, reproducibility, and recovery meeting international standards. The fertilizer is expected to support green mustard growth by enhancing critical metrics, including plant height, leaf number, and biomass accumulation. The study highlights the agronomic benefits of balanced NPK fertilization for green mustard, emphasizing enhanced nutrient absorption and sustainable agricultural practices. Furthermore, integrating this fertilizer with organic amendments may help mitigate potential soil degradation associated with prolonged use of inorganic fertilizers. The findings highlight the potential of precision-formulated fertilizers to enhance crop productivity while promoting environmental sustainability.

Abstract

Aisyiyah ialah salah satu organisasi perempuan Muslim terbesar di Indonesia. Dengan mengambil hal yang sesuai, rata-rata ibu-ibu yang mengikuti Aisyiyah adalah ibu rumah tangga. Dengan menggunakan sistem semai dan juga menggunakan pupuk organik cair, mampu membuat seluruh warga yang ikut dapat memahaminya dengan mudah. Metode yang dilakukan ialah dengan langsung terjun ke lapangan untuk memberikan pengarahan secara lansgung kepada warga yang datang. Memberikan penjelasan detail bagaimana cara melakukan sistem semai kangkung darat dengan mudah. Hasil yang didapat ialah dengan memberikan eduikasi cara penyemaian yang sesuai dan kapan benih bisa ditanam di tanah secara langsung, sebelum itu direndam dahulu dengan menggunakan pupuk organik cair merek Basill Nigr. Maka dapat disimpulkan bahwa penyuluhan secara langsung seperti ini dapat dilakukan dengan semaksimal mungkin untuk membuat para warga mampu memahami dan juga bertanya secara langsung apabila ada hal yang tidak dapat dipahami.
