AKTIVITAS ANTIOKSIDAN TUMBUHAN SURUHAN (Peperomia pellucida [L.] Kunth) ABSTRAK Penelitian ini bertujuan untuk mempelajari aktivitasantioksidan tumbuhan suruhan, dengan mengukur total antioksidan tumbuhan pada keadaan segar dan kering, serta tanpa dan dengan pemanasan. Total antioksidan diukurmenggunakan metode FRAP (Ferric Reducing Antioxidant Power) dan absorbansinya dibaca padaspektrofotometer UV-Vis dengan panjang gelombang 593 nm. Hasil penelitian menunjukkan bahwa total antioksidan ekstrak suruhan kering sebesar 3,25 mmol/100g dan ekstrak suruhan segar 0,21 mmol/100g. Total antioksidan tertinggi pada ekstrak suruhan kering dengan pemanasan 4,05 mmol/100g, diikuti oleh ekstrak suruhan kering tanpa pemanasan 2,44 mmol/100g, ekstrak suruhan segar dengan pemanasan 0,35 mmol/100g dan ekstrak suruhan segar tanpa pemanasan 0,08 mmol/100g. Penelitian ini menyimpulkan bahwa kandungan total antioksidan ekstrak suruhan kering lebih tinggi daripada ekstrak suruhan segar, dan pemanasan pada suhu 100oC selama 15 menit meningkatkan total antioksidan dalam ekstrak tumbuhan suruhan. Kata kunci: Peperomia pellucida, total antioksidan, metode FRAP ANTIOXIDANT ACTIVITY OF Peperomia pellucida [L.] Kunth ABSTRACT This research aims to study the antioxidant activity ofPeperomia pellucida, by measuring the total antioxidant of the fresh and driedplant extract, withorwithoutheated.The total antioxidantwas measured using the method of Ferric ReducingAntioxidantPower (FRAP) and the absorbance read at 593 of UV-Vis spectrophotometer. The results showed that the total antioxidant of Peperomia p. dried extract was 3.25 mmol/100g and the fresh extract was mmol/100g 0.21. Dried Peperomia p.extract with heatedhasthe highest total antioxidant(4,05 mmol/100g), followedby thedry extractwithout heated(2.44mmol/100g), the fresh extract with heated(0.35 mmol/100g) and without heated (0.08 mmol/100g). This study concluded that the total antioxidant of dried extract of Peperomia p. was higher than the fresh extract, and heating at 100 °C for 15 min increase total antioxidant of the plant extract.

In realizing professional, effective, and efficient work, as well as improvement of work system, the company requires Standard Operating Procedures (SOP). SOP is a guide or reference to perform job tasks in accordance with the function and also a tool of performance appraisal company based on technical, administrative, and procedural indicators in accordance with work procedures and work system in the work unit concerned. Problems that occurred at PT. XYZ is the absence of standardization and documentation of work standards for warehousing activities resulting in non-standard work quality. The purpose of this research is to arrange Standard Operating Procedure (SOP) based on work elements in each warehousing activities in warehouse of PT. XYZ. The result of the research is the preparation of SOP for the acceptance of coffee beans, the storage of coffee beans, the delivery of coffee beans to the production, and the delivery of coffee to the consumers.
The most important components in the company are human resources. The use of human resources is not optimal it may cause losses by companies and labor. If the amount of labor is too little, it will cause the buildup at the work station. If the labor too much, it will cause losses due to waste. In this company, the process of producing cigarette paper is divided into three main phases, namely preparation stage , the process of making paper and the finishing stages. The process of producing activities cigarette paper needs human resources optimally. The problems that arise during production process activities are the use of human resources that are not optimal, resulting in the shortage of labor and labor surplus work that is working on the work that is stacking. This study was conducted to determine when the standard work and can provide a good decision in the optimal amount of labor on the packaging of ream paper products form. Results resulting from the standard time of each element ie the element wrapping cigarette paper sheet with a standard time of 177.79 seconds, enter the box packaging packaging with the standard time, 119.20 seconds, full box with a standard price of 231.15 seconds and wrap the packaging using plastic with a standard time of 55.31 seconds. The total labor standard packaging process with the method of data as much as 15 people / shift seconds actual workforce of 13 people. Enough amount of labor as much as 2 people.
