Permasalahan: Pestisida merupakan pilihan utama cara mengendalikan hama, penyakit dan gulma. Penggunaan pestisida meluas di hampir seluruh dunia. Pestisida yang digunakan pada para petani apabila tidak digunakan secara benar akan berdampak negatif bagi kesehatan petani. Tujuan Penelitian: untuk mengetahui faktor yang berhubungan dengan gejala neurotoksik. Metode Penelitian: Jenis penelitian adalah survei analitik dengan pendekatan cross sectional. Populasi penelitian adalah seluruh petani sayuran berjumlah 37 orang yang seluruhnya dijadikan sampel. Hasil: analisis uji chi-square menunjukkan nilai penggunaan APD diperoleh p-value = 0,002, jenis pestisida p-value = 0,127, masa kerja diperoleh p-value = 0,028 dan usia diperoleh p-value = 0,001. Kesimpulan: penggunaan APD, masa kerja, dan usia berhubungan dengan gejala neurotoksik, sedangkan jenis pestisida tidak memiliki hubungan dengan gejala neurotoksik. Kata Kunci: Neurotoksik, Pestisida, Petani Sayuran

Background: Food and beverage sanitation hygiene really needs to be guaranteed of its safety, including the sanitation hygiene of home-made snacks produced by food entrepreneurs. Poor food sanitation hygiene can cause food poisoning, which is bad for buyers. Especially during the COVID-19 pandemic, food sanitation hygiene in small and medium businesses must be considered to avoid transmission while maintaining an entrepreneurial image in the midst of the pandemic. Objective: This study aims to analyze behavior changes including knowledge, attitudes, and entrepreneurial actions in food and beverages processing through mentoring using WhatsApp messenger media. Methods: This study used a quasi-experimental approach. The population of this study was small and medium entrepreneurs specializing in food and beverage processing accompanied by an incubator in North Sumatra with as many as 35 entrepreneurs. The samples of this study amounted to 29 food entrepreneurs who were selected using the purposive sampling technique. The time of the study was in July and August 2020. Data were obtained by giving questionnaires before mentoring, two weeks after mentoring, and four weeks after mentoring. The variables consisted of knowledge, attitudes, and actions, as well as assistance to use WhatsApp messenger media. The collected data were then analyzed using the Wilcoxon and Friedman test. Results: The results showed that the mentoring using WhatsApp messenger media could increase knowledge (P value = 0.000), attitudes (P value = 0.000) respondents' actions (P value = 0.015). Conclusion: The role of health workers was very necessary for the use of WhatsApp messenger based social media, including as assistants who present health promotion content, annul negative content, and make positive efforts to reconcile if there be bad communication in the WhatsApp messenger social media group.

ABSTRACT The spraying process is a condition where workers are very likely to be exposed to toxic chemicals contained in pesticides. Problems encountered in the field, workers do not spray with the correct method and do not use a complete PPE. The danger that can occur when spraying is a disturbance in the enzyme Cholinesterase (CHE) in the blood. CHE is an enzyme that is in the body's tissues has a role to keep nerve cells, muscles and glands working properly. The purpose of this study was to determine the factors related to CHE levels in spraying workers. The research design used analytical research with cross sectional approach. The population was 30 spraying workers. The sampling technique used a total population of 30 people. Data analysis used univariate and bivariate analysis tested by Fisher Exact Test statistical test. Data obtained by questionnaire and examination of CHE levels through blood samples. The results with bivariate analysis revealed p-value of each variable, namely age .143>.05, gender 1,000>.05, education level .374>.05, years of service .071>.05, duration of exposure .02<.05, spraying method 0,000<.05, the last spraying time was .210>.05 and PPE .001 <.05. The conclusion shows that there is a relationship between the length of exposure to pesticides, how to spray and PPE with CHE levels.

Reducing the stunting rate is still a national priority at this time, one of the important pillars that can be strengthened is monitoring and evaluation. One way is through early detection using the application as a monitoring medium. The implementation is the Posyandu which incidentally is the spearhead in the field, in order to strengthen the Posyandu efforts, the Posyandu needs to be supported to be economically productive and able to use the application. The method used is entrepreneurship training and application use, application use assistance, and entrepreneurial assistance. The results of this activity are able to use applications so that they are able to detect stunting toddlers early, then Posyandu has a productive business which part of the profits are used to help the operation of Posyandu
