Abstract

Background: Fatigue can reduce working performance, worker motivation, and work produc­tivity. Fatigue due to exposure to heat pressure which causes excessive sweating must be overcome through the provision of fluids that are right for workers. Coconut water contains electrolytes, so it is very good to replace lost body fluids during activities throughout the day. The purpose of this study is to analyze differences in work fatigue with interventions giving 4 liters of drinking water and giving 1 liter of young coconut water (Cocos nucifera L.) accompanied by giving 3 liters of drinking water.Subjects and Method: This study is a quasi-experimental design with a research design of one group pre and post-test design. The study population was the production of cassava chips factory workers with a total sample of 20 people. The sampling technique is purposive sampling. The dependent variable is work fatigue while the independent variable is giving 4 liters of drinking water and giving 1 liter of young coconut water (Cocosnucifera L) accompanied by giving 3 liters of drinking water. The type of data collected is primary data in the form of work fatigue (in milliseconds) measured using the Reaction Timer. Bivariate analysis was conducted using the paired T-test.Results: Fatigue after giving 1 liter of young coconut water and 3 liters of drinking water was lower (mean = 118.00; p = 0.001) than the group given 4 liters of drinking water (mean 164.94; p= 0.001).Conclusion: Work fatigue in the group given 1 liter of young coconut water and 3 liters of drinking water was lower than the group given 4 liters of drinking water.Keywords: fatigue, young coconut water, drinking water, heat pressureCorrespondence: Bona Rina Ria Rajagukguk.

Abstract

Industri percetakan menggunakan bahan kimia yang berbahaya bagi lingkungan dan manusia, salah satunya adalah senyawa organik yang mudah menguap yaitu benzena, digunakan sebagai solven (pelarut) tinta. Target utama pajanan benzena pada manusia adalah sumsum tulang belakang, yaitu tempat pembentukan sel darah. Efek terhadap kesehatan pekerja yaitu kerusakan pada sistem pembentukan darah (sumsum tulang) yang dapat menimbulkan risiko terjadinya penurunan jumlah elemen sel darah secara progresif yang meliputi penurunan kadar hemoglobin dan menyebabkan terjadinya anemia. Tujuan penelitian ini adalah untuk menganalisis hubungan paparan benzena dengan anemia pada pekerja industri percetakan. Metode penelitian ini merupakan penelitian kuantitatif dengan menggunakan desain cross sectional. Populasi sebanyak 50 orang dengan pengambilan sampel teknik consecutive sampling. Analisis bivariat dengan menggunakan uji Chi Square dan analisis multivariat menggunakan uji regresi logistik berganda. Hasil penelitian menunjukkan bahwa dari 50 orang pekerja yang mengalami anemia berjumlah 17 orang. Hasil uji chi square menunjukkan adanya hubungan antara lama paparan dengan anemia (p=0,001) dan adanya hubungan antara kadar benzena dengan anemia (p=0,016). Hasil uji regresi logistik berganda menunjukkan bahwa kadar benzena paling berpengaruh terhadap anemia, kadar benzena berpeluang untuk terkena anemia sebesar 74,6%. Saran untuk pekerja di industri percetakan hendaknya memiliki kesadaran untuk menjaga kesehatan dengan menggunakan APD selama proses produksi. Bagi pemilik percetakan hendaknya menyediakan APD yang sesuai dengan potensi bahaya di tempat kerja dan melakukan sistem rotasi kerja. Bagi pembuat kebijakan khususnya Dinas Ketenagakerjaan hendaknya membuat kebijakan dan pengawasan terkait permasalahan di industri percetakan.

Abstract

Singkong merupakan makanan pokok ketiga setelah padi dan jagung bagi masyarakat indonesia. Tanaman ini dapat tumbuh sepanjang tahun di daerah tropis dan memiliki daya adaptasi yang tinggi terhadap kondisi berbagai tanah. Pada tahun 2011 produksi singkong di Indonesia mencapai 24.044.025 ton, sedangkan pada tahun 2012 meningkat menjadi 24.177.327 ton. Salah satu olahan pangan yang berasal dari singkong adalah keripik singkong. Keripik adalah jenis makanan yang sudah dikenal masyarakat indonesia, baik yang bersifat tradisonal maupun yang sudah berskala industri. Proses pengolahan singkong dimulai dengan proses pengupasan kulit dari singkong tersebut. Proses ini biasa dilakukan dengan cara tradisional.

Abstract

Learning is a system that aims to help the learning process of students, which contains a series of events that are designed, arranged in such a way as to influence and support the learning process of students (Firdaus, 2012). According to Nasution (2000) the learning process is an interaction / process of communication between the teacher and students and between students and students. Intertwined communication should be reciprocal communication created in such a way, so that the message conveyed in the form of the subject matter will be effective and efficient. Students as the subject of learning must play an active role in learning. the activeness of students is assessed from their role in learning, such as asking questions, answering questions, giving responses and others. In addition, the activeness of students is a form of independent learning, namely students trying to learn everything about their own will and ability / business, so that in this case the teacher only acts as a mentor, motivator and facilitator. Therefore, the teacher needs to create an atmosphere of learning that can foster an attitude of collaboration between students and other students. The main problem in learning in formal education (school) today is the low absorption of students. The learning process to this day is still dominated by teachers and does not provide access for students to develop independently through discovery in the process of thinking. According to Dimyati and Mudjiono (2002) the dominance of teachers in the learning process causes students to be passively involved, students are more waiting for the presentation of the teacher rather than looking for and finding their own knowledge, skills and attitudes they need during the learning process. Therefore, it is necessary to apply new learning strategies that can make students actively participate in learning. One active learning strategy developed by Silberman (2011) is true or false active learning strategies. The learning steps in the true or false active learning strategy will activate students from the beginning of learning which will stimulate students to think and motivate students to play an active role in learning activities so that the teacher does not dominate the learning process. This strategy is marked by the teacher making statements that are in accordance with the subject matter, half right and the other half wrong. Then students discuss in their groups to state whether the statement is true or false. By discussing students can exchange opinions. According to Silberman (2011) by listening to various opinions, students will be challenged to think. our brain will do a better learning process if we discuss information with other people. When the learning process is passive, the brain cannot store information properly. In answering questions, students are required to give reasons why they answer correctly and why they answer wrongly. This is so that students do not guess when answering and will make students better understand the material. Then the results of the group discussion will be presented in front of the class, students are given the opportunity to ask questions, answer questions and respond or give opinions. This will activate students more in learning and can train students' courage. According to Silberman (2011), learning activities carried out with the activities of students themselves will cause a knowledge to be more meaningful and can last a long time in memory of students so that the learning outcomes achieved will be better. Based on the results of the study obtained values from the first and second cycles in a row - according (77.33%), and (80.00%).
