Background: Buprenorphine is quite common in the illicit market. Buprenorphine-containing drugs abuse is frequently encountered in patients. The analysis methods used to determine the abuse of buprenorphine and norbuprenorphine are important for forensic science. Buprenorphine is metabolized to norbuprenorphine by the liver. Objective: Therefore, the determination of buprenorphine and norbuprenorphine in urine is one of the methods to determine the abuse of buprenorphine. Methods: In this study, we have developed a precise, simple, and rapid ultra-performance liquid chromatographytandem mass spectrometer method for the determination of buprenorphine and norbuprenorphine simultaneously. Results: The developed method was validated in terms of selectivity and linearity, which was in the range of 9–1800 ng/mL for both buprenorphine and norbuprenorphine. The intra-assay and inter-assay accuracy and precision were found within acceptable limits of the EMA guideline. Lower limits of quantitation were 9 ng/mL for both buprenorphine and norbuprenorphine. Conclusion: The developed method was successfully applied for the determination of both analytes in the proficiency testing samples.

Kangkung hidroponik menjadi kangkung rendang merupakan kegiatan yang dapat meningkatkan nilai tambah, menghasilkan produk yang dapat dikonsumsi, serta menambah pendapatan dan keuntungan produsen.Tujuan penelitian untuk menguraikan apa saja tahapan pengolahan kangkung hidroponik menjadi kangukung rendang, menganalisis biaya produksi, penerimaan, dan pendapatan, menganalisis nilai tambah pengolahan kangkung hidroponik menjadi kangkung rendang, menganalisis apakah usaha pengolahan kangkung hidroponik menjadi kangkung rendang layak diusahakan. Penelitian ini dilakukan di Jalan Bromo lorong Amal Medan Denai Kota Medan. Penentuan daerah penelitian dilakukan secara purposive, Metode pengambilan sampel secara sensus yaitu usaha Syifa Hidroponik dengan pengambilan data ulangan selama 2,5 bualan sebanyak 10 kali ulangan. Hasil penelitian: 1) Tahapan  pengolahan kangkung hidroponik menjadi kangkung rendang yaitu:  Penyediaan bahan baku kangkung hidroponik, kangkung dihaluskan, pengadonan kangkung, telur ayam, tepung beras dan garam, kangkung dikukus, kangkung didinginkan, dipotong-potong, digoreng, pemasakan bumbu rendang, pencampuran kangkung yang digoreng dengan bumbu rendang dan pemasaran. Total biaya pengolahan kangkung hidroponik menjadi kangkung rendang untuk sekali produksi sebesar Rp 545.291,83, penerimaan sebesar Rp 1.500.000,00, per sekali produksi dan pendapatan sebesar Rp 954.708,17 per sekali produksi. Nilai tambah yang dihasilkan dari pengolahan kangkung hidroponik menjadi kangkung rendang tergolong tinggi dengan rasio nilai tambah 75,31% > 50%.Usaha pengolahan kangkung hidroponik menjadi kangkung rendang layak untuk diusahakan dengan nilai R/C rasio 2,75 > 1.  Abstract  Hydroponic water spinach into rendang water spinach is an activity that can increase added value, produce edible products, as well as increase producer income and profits. The purpose of the research is to describe what are the stages of processing hydroponic water spinach into rendang kangukung, analyze production costs, revenue, and income, analyze added value of processing hydroponic water spinach into rendang water spinach, analyzing whether the business of processing hydroponic water spinach into rendang water spinach is worth the effort. This research was conducted in Jalan Bromo Amal Medan Denai alley Medan City. Determination of the study area was done purposively, census sampling method that is Syifa Hydroponic business with retrieval data retrieval for 2.5 boasting as many as 10 replications. The results of the study: 1) The stages of processing hydroponic water spinach into rendang water spinach, namely: Provision of raw materials for hydroponic water spinach, crushed water spinach, stirring water spinach, chicken eggs, rice flour and salt, steamed water spinach, water spinach water spinach, cut into pieces, fried, fried spicy water spinach, cooking water spinach kale, chicken egg, rice flour and salt, steamed water spinach, water spinach kangkung cooled, cut, fried, cooking spices, rendang, mixing fried kale with spicy rendang and marketing. The total cost of processing hydroponic water spinach into rendang water spinach for one production is Rp. 545,291.83, revenue is Rp. 1,500,000.00, per production and income is Rp. 954,708.17 per production. The added value generated from the processing of hydroponic water spinach into rendang water spinach is classified as high with a value added ratio of 75.31%> 50%. The business of processing hydroponic water spinach into rendang water spinach is feasible to be cultivated with an R / C ratio of 2.75> 1.
