Abstract

This research was conducted to identify simplicia microscopically, phytochemical screening and determination of total flavonoid content of extract and ethyl acetate fraction from Moringa (Moringa oleifera L.) leaves using UV-Visible Spectrophotometry method. The experimental design used in this study was to perform microscopic identification of Moringa leaf powder simplicia, make 96% and 70% ethanol extract and ethyl acetate fraction of Moringa leaves from 70% ethanol extract, then carry out phytochemical screening and determination of total flavonoid content with quercetin standards. Phytochemical screening on the ethyl acetate fraction of Moringa leaves included tests for the content of flavonoids, saponins, tannins and alkaloids. The results of microscopic identification of Moringa leaf simplicia showed the presence of calcium oxalate crystals in the form of rosettes, mesophyll and stomata. The result of determination of total flavonoid content in 96% ethanol extract was 16.69 ± 0.74% (w/w), 70% ethanol extract was 10.84 ± 0.49% (w/w), Moringa leaf ethyl acetate fraction 14 .45 ± 0.90% (w/w). The highest total flavonoid content was found in the 96% ethanol extract of Moringa leaves in accordance with the 2017 Indonesian Herbal Pharmacopoeia, that the thick extract of Moringa leaves containing no less than 6.30% (w/w) total flavonoids was calculated as quercetin.

Perjanjian kerja dapat dilakukan secara lisan maupun tulisan. bagaimana implementasi makna batal demi hukum dalam perjanjian kerja yang bertentangan dengan Undang-Undang Nomor 13 Tahun 2003 Tentang Ketenagakerjaan. Penelitian yang digunakan adalah penelitian hukum normatif yaitu sebuah metode penelitian hukum yang dilakukan dengan meneliti bahan pustaka atau data sekunder. Sumber data sekunder yaitu berupa dokumen-dokumen tertulis, peraturan perundang-undangan dan litelatur-litelatur yang berkaitan dengan objek penelitian ini. Makna batal demi hukum berarti perjanjian kerja tersebuat seolah-olah tidak pernah ada atau sejak semula secara yuridis tidak pernah ada perjanjian. Namun dalam kenyataan yang sering terjadi walaupun pekerjaaan tersebut batal demi hukum ada tetapi pekerja atau buruh masih tetap diperkerjakan hingga saatnya terjadilah pemutusan hubungan kerja. Kata Kunci : Batal Demi Hukum, Perjanjian, Kerja Abstract The working relationship is basically the relationship between the worker/laborer and the entrepreneur after a work agreement has been made. The work agreement is the beginning of a work relationship that is made based on a statement of commitment between the worker/laborer and the entrepreneur. Work agreements can be made orally or in writing. how to implement the meaning of null and void in work agreements that are contrary to Law Number 13 of 2003 concerning Manpower. The research used is normative legal research, namely a legal research method that is carried out by examining literature or secondary data. Secondary data sources are in the form of written documents, laws and regulations and literature related to the object of this research. The meaning of null and void means that the work agreement is as if it never existed or from the beginning there was never an agreement legally. However, in reality, what often happens is that even though the work is null and void, workers or laborers are still employed until the time when the employment relationship is terminated.

Abstract

As the years progress in Indonesia, the price and production of chilies tends to fluctuate. This is due to an increase in input costs or production facilities which increase every year, causing price factors for farmers and consumers to tend to change. This literature review analysis aims to determine: (1) factors that significantly influence chili price fluctuations; (2) the influence of production efficiency on the productivity of chili farmers; (3) the influence of marketing channels involved in red chili farming on price fluctuations. The method used is descriptive analysis method with literature study. The results of the literature show that factors that significantly influence price fluctuations are production costs, production facilities, selling price factors, weather factors, use of technology, length of the supply chain where the longer the marketing channel, the higher the price received by final consumers while prices at the farmer level do not experience increase, as well as the availability of red chilies on the market, where if the availability of red chilies is abundant on the market it will cause a decrease in prices at the farmer and consumer level. The results of literature observations show that these three topics are mutually sustainable. So there is an opportunity for further research related to the three subjects for more accurate measurements based on findings in the field.

Abstract

CV Cielofood Pratama is a beverage processing business with nutmeg raw materials, located in Bogor City, West Java. The company produces syrups with varying sizes of packaging. The multi-stage production process does not rule out the possibility of irregularities that could cause the product to no longer meet the quality standards we set. In general, business units have a profit goal for business sustainability, by seeking efficiency in operations in order to obtain profitable profits. Analysis of the data shows the difference between corporate policy and the results of the EOQ method. The company usually orders 25 kg of raw materials with a frequency of 120 times per year. However, the EOQ method recommends ordering 144 kg with a frequency of 36 times per year. In addition, there is a significant difference in the total cost of supplies, which is IDR 30,900,000 according to company policy and IDR 10,392,000 according to EOQ method. This study aims to analyze strategies in raw material supply as an effort for supply chain efficiency. Using the Economic Orders Quantity (EOQ) method Reduce storage costs, save space on both storage and workspaces, resolve problems and reduce the risk that raw material supplies may pose.

Abstract

This study aims to analyze the effect of interest rates on inflation in Indonesia over the past 20 years using simple linear regression methods. Data is obtained from secondary sources such as national journals, the Central Bureau of Statistics (BPS), and Bank Indonesia from 2004 to 2023. The results of statistical analysis show that interest rates have a strong relationship with inflation, with a correlation of 74.4%. The interest rate variable is able to explain 52.8% of the variation in the model regarding its effect on inflation. Simple regression analysis confirms that interest rates have a positive effect on inflation in Indonesia. In this context, every 1% increase in interest rates results in a 1.1% increase in inflation. Hypothesis testing results also show that the effect of interest rates on inflation is statistically significant. The implications of this study underscore the important role of interest rates in monetary policy to control inflation, as well as the need for an in-depth understanding of the economic factors that influence it. In conclusion, this study contributes significantly to the understanding of inflation dynamics in Indonesia, especially in the context of its relationship with interest rates. The results are expected to be an effective foundation for the development of better monetary policy in managing inflation in the future.

Abstract

Educational aids are very helpful in improving students' understanding of abstract subjects such as exact sciences. The Strength of Materials (SOM) course in the Manufacturing Design Engineering Department is supported by practical activities in the SOM studio using teaching aids, including truss bar tests. However, the currently used teaching aids have been complained about by students due to their complexity. Therefore, the development of a more user-friendly truss teaching aid prototype is needed. This article focuses on the evaluation of the impact of the developed teaching aid on its suitability for use in easier operations. The method used is observation techniques and interviews with students who have tried the previous teaching aids and the prototype being developed. The results showed that the prototype developed was better than the previous tool, because the procedure for using the tool was simpler and the duration of disassembling and assembling the test specimens was faster. Thus, it can be stated that the developed truss test teaching aid prototype is easier for students to use than the previous tool used in the SOM studio. Therefore, the development process and performance tracking of the developed prototype can be carried out at the next development stage.
