Cooking oil is one of the basic human needs as a food processing material. Cooking oil serves as a very important frying medium and its needs are increasing. The purpose of this study was to determine the effectiveness of bagasse which was activated with HCl in increasing the quality of used cooking oil.This study uses bagasse as an adsorbent. The oil used is packaged cooking oil which is used for three times frying. Activation of activated carbon using 0.1 N HCl was tested for quality.Test results obtained for free fatty acids (FFA) from new cooking oil is 0.1115%, used cooking oil before being given activated carbon is 1.0275%, and used cooking oil after being given activated carbon varies between 20, 30, 40 minutes. respectively 0.4032%, 0.2551%, 0.4508%. While the test results obtained for the peroxide number of new cooking oil is 2.0110 meq / kg, cooking oil used three times frying before being given activated carbon 7.0156 meq / kg, used cooking oil after being given activated carbon with contact variations of 20, 30, 40 minutes respectively 6,6685 meq / kg, 6,0088 meq / kg, 5,3366 meq / kg. From the results above the levels of free fatty acids and peroxide numbers have met the requirements of SNI: 2012. From the results obtained it can be concluded that bagasse charcoal can improve the quality of used cooking oil in accordance with SNI 7709; 2012.

Blood donation activity is the obligation of every community as a form of concern for others. Many people do not know about the health benefits of blood donation. There are even people who are reluctant to donate blood because they are worried about the side effects it causes.

This activity was carried out by conducting a site survey with the implementation team, meeting with Representatives of PERSIT KCK HUBDAM I/BBU, Medan, North Sumatra. This activity was opened by the presenter, after that singing the Indonesia Raya anthem, welcoming remarks, followed by blood donation activities, blood sugar checks, a careful echo talk show and ended with a group photo. Implementation of community service in the form of social services in educating the public on the importance of blood donation, blood sugar checks and careful echo talk shows. Health Checkup has many benefits. When donating blood, the blood cells in the body are replaced more quickly with new ones. If you donate blood once every three months, your body will stay healthy. Besides being useful for helping others, blood donation also makes our bodies healthier.

The rhizome is part of the plant for food reserves, including storing carbohydrates (starch), therefore rhizomes of Galangal, Curcuma, Fingerroot rhizome can be used as a source of starch. This study used an exploratory method which included isolation of starch from Galangal, Curcuma, Fingerroot Rhizome, macroscopic examination, microscopic examination, sample collection, sample processing, and examination of the characterization of starch. The results of starch characterization obtained yields for Galangal starch 2.6%, Curcuma starch 5.4%, Fingerroot rhizome starch 4.1%; determination of total ash content for Galangal starch 1.4%; Curcuma starch 2.0%, Fingerroot rhizome starch 1.0%; determination of drying shrinkage for 1.8% Galangal starch, 2.4% Curcuma starch, 3.2% Fingerroot rhizome starch; determination of acid-insoluble ash content for 0.6% Galangal starch, 0.7% Curcuma starch, 0.7%Fingerroot rhizome starch.
