Utilization Conventional Market Waste on Catfish Food Production

Tamora Catfish Company as a Micro, Small and Medium Enterprise (UMKM) which one of the Universitas Sumatera Utara community service partners, used a simple microbubble technology system to increase the dissolved oxygen content in pond water in order to anticipate of the large number of die fish because of the polluted pond water, which impacted in reducing the amount of oxygen. Biofloc application was observed decreasing the ammonia content and generating natural feed. This was analyze by the team that already implemented this simple technology in the first year observation which found its successfully reduce fish mortality and increase the number of catfish. However, the catfish food is expensive because it is depend on pellet feed, so the production process costs are very high. Via a multi-year system, community service team utilizes conventional market waste as a feed in order to replace the use of costly pellet feed. The solution was starting from processing conventional market waste such as vegetables waste. It was considered because it is cheap and it needs simple machine technology to produce the feed. The machine will construct by copper and mixer in order to produce feed that suitable for catfish food. Furthermore, it also impacted to make conventional market cleaner from waste since partners collect and process the waste directly.

Productivity Analysis Of Filling Machine With The Objective Matrix (OMAX) Method

A Factory is a manufacturing industry that produces tea drinks in cups. A Factory is also inseparable from problems related to machine/equipment productivity. Based on the results of observations made at A Factory part of the production line that there is often a sudden stop of the production process. The discontinuation will affect the quality of the product expected and the production targets to be achieved. The problem was discussed in this research is how much the productivity level of the filling production department is, how much the production effectiveness, effective working hours, the number of defective products, and machine downtime criteria. The productivity measurement method used is the Objective Matrix (OMAX) method, so the steps of this study refer to OMAX steps, which is the criteria determination/productivity ratio of the production line, the calculation of the productivity ratio value, the calculation of the initial standard score (score 3), The determination of the goal (score 10) and the lowest score (score 0), the determination of weight, the calculation of value/criteria value, the determination of productivity value for each period, determination of index percentage. With the OMAX method, it can be seen that in period 11 (compared to period 10) there was an increase in productivity, this can be seen because the IP value (Index of Performance) which is positive (+) is 27.79 and there is an increase in the value of the calculation at the time of measurement (current) from 383.36 to 300. This increase was due to an increase in the value of all criteria.

Development of teaching materials based on learning video using movavi education set at Yayasan Perguruan Tunas Karya Batang Kuis

The COVID-19 pandemic that has recently hit various countries including Indonesia has resulted in major changes in various fields, including in the development of the education sector. The teaching and learning process has turned from face-to-face into an online method. However, there are several obstacles experienced by schools that implement an online learning system, one of them was the ability of teachers who do not understand various learning application platforms. In addition, the material provided by the teacher is not maximally acceptable to students because most teachers provide learning material from the pages of textbooks or teacher writings (scans, photos, or presentation files). For this reason, it is necessary to have variations in the provision of teaching materials to students by making interesting and creative learning videos using the Movavi Education Set. With learning videos, students can do lessons at home, repeat it, and can ask the teacher some points from it if they don't understand. By using Movavi Education Set, teachers are also free to be creative in making learning videos that can be shared through commonly used communication applications such as e-mail, WhatsApp, line, google classroom and other applications.

The The Role Of Von Willenbrand Factors As The Early Detection Of Endotel Cell Damage In Youth Ages With Obesity In The Usu Medan Campus Environment

Preliminary : Endothelial cells are a single layer that lines the entire vascular system. Endothelial dysfunction can be triggered by several main things, namely physical stress, oxidative stress and irritant substances. Obesity triggers an inflammatory process and metabolic disorders that will lead to increased oxidative stress. Long-term oxidative stress will cause damage to cells and tissues and trigger degenerative diseases. Damage to endothelial cells is expected to be detected by examining Von Willenbrand levels so that it can prevent complications of vascular disorders early.

Promotive and preventive programs about basic life support in Medan Barat district

Cardiac arrest remains a prominent public health problem and cause of death globally. Despite there is no national data of Indonesia available currently, around 350,000 people in the United States and Canada experienced an arrest every year, and half of them were dead. The community knowledge and awareness about basic life support, particularly among mothers, is still low. Therefore, they cannot contribute effectively in providing first-aid to reduce the mortality. To improve this situation, we need an education and training program about basic life support for the PKK mothers and Posyandu cadres in West Medan to reduce the mortality rate of cardiac arrest in Indonesia. The activity was conducted in several stages, from basic data collection, lectures, basic life support practical training, evaluation and guidebooks handover. It was attended by 26 people, 15 women (57.7%) and 11 men (42.3%), with a mean age of 39 years old. No significant change was found in the level of knowledge and behavior before and after the activity (Z-score: 0,001; p= 1,000).
