Abstract

Recently, low-carbon steel is often used as a basic material for automotive spare parts on the market. This study aims to improve the quality of carbon steel which is not inferior to that made by manufacturers where the price is relatively affordable by carrying out pack carburizing. This study used the pack carburizing method, AISI 1020 low-carbon steel as a starting material and used fine coconut shell charcoal powder as a carbon source mixed with Na2CO3 as an energizer. Pack carburizing uses temperature variations of 850oC, 875oC and 900oC, aims to find out how the results of hardness and microstructure values for variations of temperature and holding time. And also use SAE 20w-40 oil as a quenching medium. The highest hardness results were obtained on specimens with a heating temperature of 900oC with a holding time of 60 minutes, with an average hardness value of 54.21 HRC. Accompanied by the phase formed, namely 61% pearlite 39% ferrite.

Abstract

 Community stewardship can be done directly. Direct interaction is commonly applied, appreciated, and easy to communicate. During the COVID-19 pandemic, direct interaction and visits are almost impossible due to activity limitations and social distancing. Online and semi-online interaction can be applied by inviting community limited representatives combined with the online method. Initiation on online communication is introduced. This project was conducted in companionship and training in Braja Harjosari and Labuhan Ratu VII, East Lampung. Following the introduction of the online and semionline methods, local people can apply and share their knowledge of the new normal paradigm.

Abstract

The Sugar Factory uses more than 150 pieces of equipment in production process. With so many tools, the possibility of accidents also very large, especially because of the age of mechine and equipment. On July 22 2022, an accident occurred which resulted 1 (one) person dying as a result of being hit by a lifting beam and sugarcane scale due to a broken wire rope. Investigation and analysis of the causes of accidents as well as follow-up actions must be carried out, because the production process must continue. This research aims to analyze accidents that occur based on human factors using Government Regulation and Human Factor Analysis and Classification System (HFACS) approach. Government regulations are used to identify the types of accidents with a major impact on lost work hours and fatalities. Government regulations are used to determine the types of accidents that have a major impact on lost work hours and deaths. Using data from sugar factories and interview results, this study shows that accidents with the greatest impact are caused by lifting equipment. Using the Human Factor And Classification System (HFACS) method to analyze the 6 accidents, the results show that at level 1, the biggest causes of accidents are at the sub-level decision error, skill-based error, perceptual error and routine violation. At level 2, the biggest causes of accidents are at the sub-level technological environment and personal readiness. While at levels 3 and 4, Failed to correct problem and supervisory violation have the largest percentage at level 3 and resource management at level 4. The conclusion shows that there are still various problems from the human factor to implementate occupational safety which could potentially lead to accidents.

Abstract

Fraktur adalah kondisi tulang retak atau patah. Meskipun mampu menahan tekanan atau benturan hingga batas tertentu, tulang akan patah jika tekanannya terlalu besar. Kompres dingin dapat menjadi salah satu cara untuk menurunkan nyeri pasca operasi ORIF (Open Reduction and Internal Fixation). Kompres dingin membantu mengurangi peradangan, pembengkakan, dan nyeri dengan cara mempersempit pembuluh darah, mengurangi aliran darah ke area yang cedera, dan menurunkan sensitivitas saraf. Laporan kasus ini bertujuan untuk mengetahui efektifitas penerapan kompres dingin untuk menurunkan tingkat nyeri pada pasien post ORIF Proximal Femur. Metode pada laporan kasus ini adalah studi kasus pada pasien post ORIF Proximal Femur karena ketidaknyamanan rasa nyeri. Dilaukan dengan intervensi kompres dingin 2 kali dalam 1 hari selama 3 hari. Instrumen yang digunakan yaitu menggunakan Numeric Rating Scale (NRS). Hasil laporan kasus ini menunjukkan bahwa dengan diberikan intervensi kompres dingin selama 3 hari terjadi penurunan tingkat nyeri yang signifikan dari skala 5 menjadi skala 2. Kompres dingin ini sebagai terapi non farmakologis yang efektif dalam standar intervensi asuhan keperawatan untuk menurunkan skala nyeri post ORIF Proximal Femur.

Abstract

Mental disorders are health problems that affect the quality of life. The presence of People with Mental Disorders in the family affects financial capacity because destructive behavior increases the financial burden. Improving health is an investment in development through productive social and economic life. Efforts to improve health must be carried out together with increasing family economic independence. Ecoprint is a business choice because it is environmentally friendly and in demand by the community. This community service activity carries the theme of economic independence for People with Mental Disorders families by optimizing the role of cadres as drivers through Ecoprint entrepreneurship. Cadres are given entrepreneurship training, until a business unit is realized. Furthermore, cadres become the driving force for People with Mental Disorders families to be trained to make ecoprints to become a source of income. The purpose of the activity was to increase participants' knowledge and skills in making ecoprints. The activity was carried out for 2 days. The results showed an increase in participant knowledge from an average pretest of 56.7 to 82.1 posttest. There was an increase in cadre skills, the production results were 20 tote bags and 10 pieces of ecoprint cloth that were ready to be marketed. Ecoprint has great potential to be in demand by the market because it follows fashion trends and is considered environmentally friendly. Optimal support from all parties is highly expected for the smooth running of cadre assistance efforts in realizing the economic independence of People with Mental Disorders families.

Abstract

Lack of nutrition in pregnant women can cause abortion, low birth weight (LBW), premature birth, or even stillbirth during labor. Low levels of knowledge cause mothers to not understand how to fulfill the nutritional needs of pregnant women during their pregnancy. This activity aimed to increase pregnant women's knowledge of nutrition during pregnancy. The population was 10 pregnant women in the Pregnant Women's class in Kedungbanteng village. The method of the activity was to provide education through counseling, providing leaflets, and conducting pretest and posttest evaluations. The activity was carried out on Saturday, March 22, 2024, by a service team from Stikes Ganesha Husada Kediri. The results of the study showed that education for pregnant women increased knowledge about: Healthy eating patterns for pregnant women, benefits of healthy eating patterns for pregnant women, problems related to eating patterns for pregnant women, nutritional needs for pregnant women, signs and symptoms of malnutrition in pregnant women and the impact of nutritional status on the labor process. The result showed that before education, the number of pregnant women who had good knowledge was 3 people (30%), sufficient knowledge was 2 people (20%), and poor knowledge was 5 people (50%). After the intervention, the number of pregnant women who had good knowledge was 8 people (80%), sufficient knowledge was 1 person (10%) and poor knowledge was 1 person (10%). This revealed that education through pregnancy classes needs to be carried out and evaluated routinely by the midwife in charge, so that pregnant women have broad knowledge and insight and can make the right decisions in preparing for childbirth and the baby will be born healthy and safe as well as the mother healthy and safe without complications. The cadre mother should patiently provide assistance during pregnancy and childbirth.
