As students who tend to be oriented towards in-depth knowledge and understanding, analysis is key in making decisions regarding coffee consumption. In this case, coffee content analysis is the main factor taken into consideration in determining their choice. The findings of this study indicate that students consider various factors in their decisions in choosing the type of coffee based on its ingredients. Influencing factors include caffeine, antioxidants, fat, and sugar content. College students have different preferences regarding the level of caffeine in coffee, which can be influenced by their energy needs and their tolerance level for caffeine. The aim of this research is to analyze the factors that are the main considerations for students in determining the choice of coffee based on its content. This research uses a qualitative and quantitative approach that focuses on questionnaires with a 1-4 Likert scale and bold interviews. The number of participants in this research was 53 people and was reduced to 6 people being interviewed. This qualitative and quantitative approach shows that analysis of factors in selecting coffee based on its content is not a benchmark for coffee consumption. The coffee consumed by several respondents is adjusted to their body condition or personal health. The factors that become a benchmark for choosing coffee consumption are not based on its content but based on needs and health.

Obesity is a result of excessive energy consumption, this excess energy is stored in the body as fat, so that over time the body becomes heavier. This condition can be experienced by everyone, regardless of gender group or group of teenagers to adults. The aim of the research is to determine the effect of nutritional education about obesity using animation media on knowledge and attitudes in obese adolescents. This research was conducted at SMP Negeri 1 Lubuk Pakam. The research was conducted in May 2023 with quantitative methods using a Group Pre and Post Test design. Intervention in the form of counseling using animation media was given 3 times. The population in this study was class VIII, 319 students. The sample in this study was 32 obese students who met the criteria for being a sample. Data were collected using a knowledge and attitude questionnaire using a statistical test, namely the T-dependent test. The research results showed that the average knowledge of teenagers about obesity before counseling was 10.09, after being given counseling was 13.25 with a significant value of p=0.000. The average attitude score before being given counseling was 39.53, after being given counseling was 51.19 with a significant value of p=0.000. The conclusion of this research is that there is an influence of nutrition education about obesity using animation media on the knowledge and attitudes of teenagers at SMP Negeri 1 Lubuk Pakam.

Along with the current developments, electricity has become a basic need that must be required. With population growth, economic development, and an increase in various activities and the use of facilities that require electricity, the use of electrical energy will continue to increase even in the use of lights as lighting in offices. The expected purpose of this study is to examine the efficiency of energy use as office lighting for one of the fertilizer industries before and after using LED lights, as well as analyze the costs incurred and the economic value obtained from the use of LED lamps. In this study, several data are needed, such as building plan data, inventory of the types of lamps used, electrical energy consumption, and the price of electricity consumption per kWh through the calculation method. The difference in costs incurred for the use of non-LED lamps into LED lamps is IDR 580,931.14 in the 1st-floor office building in one of the fertilizer industries and IDR 319,747.56 in the 2nd-floor office building in one of the fertilizer industries. Based on this, the difference in costs incurred is very large, so the use of LED lamps is the main alternative in saving energy and costs. Therefore, it is important to conduct studies and research on the impact that can be caused by the use of LED lights on energy consumption and electricity cost efficiency in the company.    

The work of farmers is prone to the risk of health problems such as pain in the joints and fatigue.

In the third measurement, the smallest percentage was 3.96 kcal/min with a mild classification, and the largest percentage was 6.39 kcal/min with a moderate classification. The smallest rest time was 12.65 minutes and the largest rest time was 120.39 minutes. In conclusion, the mean %CVL was 13.21% with no fatigue, 86.79% with improvement needed. Average energy consumption with mild classification with a percentage of 4.21% and moderate classification with a percentage of 6.26%. The smallest rest time is 12.65 minutes while the largest is 120.39 minutes

Street lighting is a safety infrastructure on the highway. However, currently most of the public street lighting lamps do not comply with the provisions of the Indonesian National Standards Agency (BSNI). It is necessary to plan for lamp replacement by using lamps that are appropriate to field conditions, so that the light intensity produced is in accordance with established standards. Jalan Jenggolo Asri - Randu Asri in Sidoarjo is an example of a road that requires planning for lighting changes. This road is a type of secondary collector road with a length of 2500 meters and a road width of 6 meters. The lighting on this road does not meet the standards set by BSNI 7391: 2008 caused by several lights that go out and the power of the lights used is not optimal. Planning for replacing public street lighting is needed on this road by recalculating the maximum light intensity requirements. The method that can be done is to replace the lamp used with an LED lamp. In the current initial conditions, street lighting on this road uses 250W SON and 150W LED lamps. After planning, the lights will be replaced with 100W LED lights. The planning results show that by using a 100W LED lamp, a handlebar ornament angle of 14.06° will be produced, the light intensity is Candela, the lighting intensity is 6.77 Lux, and the power required per day is 26.4 kWh. Comparison with the use of 250 Watt SON lamps shows that the use of 100W LED lamps is more efficient in energy consumption by 51.76%. The results of this planning have met the standard requirements for secondary collector roads. Thus, by replacing the lights according to the plan, it is hoped that street lighting on Jalan Jenggolo Asri - Randu Asri Sidoarjo can meet the standards set by BSNI 7391:2008 and provide optimal light intensity with more efficient energy use.

Background: The burden of malnutrition in Indonesia is quite large, with more than a quarter of the adolescent population aged 16-18 years, 27 percent experiencing stunting and 8 percent being underweight, the prevalence of anemia in young women aged 13-18 years is 22.7 percent. The highest prevalence of chronic energy deficiency (CED) in women of childbearing age is experienced by adolescents aged 15-19 years, reaching 36.3%. Nutritional problems in adolescents have serious implications for the health of young people, affecting the well-being of current and future generations, as well as the economy and health of countries. In particular, the nutritional status of adolescent girls is closely related to pregnancy outcomes and the health and survival of mothers and children. Objective: To identify the diversity of food consumption and nutritional status of young women who live in boarding houses Methods: This study is an analytic observational study with a cross-sectional design that aims to identify the diversity of food consumption and nutritional status of female adolescents living in boarding houses. The sample in this study were young women who had just entered higher education at the age of 18-19 years, who lived in boarding houses, totaling 49 people. The diversity of food consumption was identified using the Semi Food Frequency Questionnaire (FFQ). Nutritional status was assessed based on body mass index and upper arm circumference. Results: The diversity of food consumption of respondents was low at 46.9%, the nutritional status based on BMI was mostly in the normal category, namely 71.42%, the nutritional status based on the LiLA category was lacking, namely 46.93%, there was no relationship between BMI and diversity in food consumption (P Value 0.13, but there is a significant relationship between the diversity of food consumption and LiLA (P Value 0.02). Conclusion: Diversity in food consumption is low and there are nutritional problems in young women living in boarding houses.
