Abstract

The COVID-19 pandemic outbreak in 2019 significantly impacted various aspects of societal life, particularly in education. The shift to online learning, necessitated by the pandemic, posed numerous challenges for teachers and students at SMA Negeri 2 Rantau Selatan. This study aims to comprehensively understand these difficulties faced by 11th-grade teachers during online instruction. Employing a qualitative descriptive approach, the findings reveal several challenges: difficulties in delivering the curriculum, evaluating students' understanding, and creating engaging online learning environments. Quantitatively, 75% of teachers reported significant challenges in curriculum delivery, 60% found it difficult to assess students' comprehension, and 70% struggled with maintaining student engagement. These findings suggest a need for more active and creative teaching methods, supported by adequate facilities from the government. The implications of these findings highlight the necessity for improved educational practices and policy recommendations to better support online learning.

Abstract

Limited agricultural land has caused a decline in the productivity of green mustard (Brassica juncea L.) as one of the nutritious vegetables that is widely consumed by the public. Cultivating vegetables using a hydroponic wick system is a solution to increase the productivity of green mustard. The expensive price of nutrient solutions can be combined with eco enzymes as a provider of essential nutrients for plants. This research aims to determine the effect of the combination of AB mix with eco enzyme on the growth of green mustard. The research was designed with RAL, 8 treatments, and 3 replications. Treatments include A1E0=AB mix 100%+0mL/L eco enzyme, A1E1=AB mix 100%+1mL/L eco enzyme, A1E2=AB mix 100%+2mL/L eco enzyme, A1E3=AB mix 100%+3mL eco enzyme, A2E0=AB mix 75%+0mL eco enzyme, A2E1=AB mix 75%+1mL/L eco enzyme, A2E2=AB mix 75%+2mL/L eco enzyme, and A2E3=AB mix 75%+3mL/L eco enzyme. The parameters measured were plant height, number of leaves, wet weight of roots and shoots, dry weight of roots and shoots, and leaf area. Data were analyzed using analysis of variance and DMRT testing with α=0.05. The combination of AB mix with eco enzyme had no effect on plant height, number and area of leaves, and wet weight of roots and shoots. However, the highest dry weight of roots and shoots in the A2E2 treatment showed significantly different results from the control treatment (A2E0). Eco enzymes act as nutrient substitutes which are influenced by sunlight, plant metabolism and water absorption capacity.

Abstract

The referral system is a healthcare management system that carries out the transfer of mutually accountable responsibilities for a specific medical case or health problem either vertically, meaning from a less capable unit to a more capable unit, or horizontally, meaning among units of similar capabilities. The referral system regulates the flow of where someone with a particular health problem should seek examination for their health issues. The purpose of this research is to analyze the Implementation of Outpatient Referral for Participants of the Health Social Security Agency (BPJS Kesehatan) at Mataram Community Health Center. The method used in this research employs a qualitative descriptive approach to gain an overview of the analysis of outpatient referral implementation for BPJS Kesehatan participants at Mataram Community Health Center. Descriptive means that the data collected are in the form of words, images, and not numerical values. The findings of the research indicate that the implementation of outpatient referral at the Community Health Center shows that it has not fully run smoothly. Patient knowledge varies, with some understanding and others not understanding. The facilities and infrastructure are still lacking, some diseases diagnosed under code 144 are still referred, many referrals are initiated by the patients themselves, and there are outpatient referrals from outside healthcare facilities.

Abstract

Chlorophyll is a green pigment in plants which is important for the process of photosynthesis. The photosynthesis process affects plant growth. Seaweed extract has been proven to be a source of biostimulants that can increase plant growth, one of which is Padina minor. Concentration and frequency are important factors that influence the work of biostimulants. One effort to increase the effectiveness of biostimulants is by changing the crude extract into the form of nanoparticles. This research aims to analyze the effect of concentration, frequency, and interaction between concentration and frequency of crude extract and Padina minor nano extract on chlorophyll levels in soybean plants. The method used was a completely randomized design (CRD) in factorial consisting of 2 factors and 4 replications. Factor A concentration of Padina minor extract, namely control, crude extract 0.4%, nano extract 0.2%, 0.3%, 0.4%, 0.5% and 0.6%. Factor B is the frequency of administration of Padina minor extract, namely 1, 2, and 3 times administration. Based on research that has been carried out, the results showed that administration of 0.4% crude extract increased the average chlorophyll a level by 6.6% and a total of 11%. Meanwhile, chlorophyll b gave the same results as 0.3% nano extract, namely an increase of 14% compared to the control. The total frequency of administration of Padina minor extract was 3 times, and the same as the other treatments, increasing chlorophyll a levels by 4.6%, b by 5.2%, and a total of 4.9% compared to the control. The interaction between concentration and frequency of administration of Padina minor nano extract gives the same results as the crude extract, with lower concentration and less frequency of application in increasing levels of chlorophyll a, chlorophyll b, and total chlorophyll in soybean plants.

Abstract

This research aims to determine the physical and chemical quality of dug well water in the area where shrimp paste (terasi) is produced at Jor Hamlet, Jor Village, Jerowaru Subdistrict, East Lombok Regency. The research method used was experimental, focusing on parameters such as temperature, pH, TDS, and hardness based on the Indonesian National Standard (SNI) guidelines. Three sampling points of community dug well water were selected with sampling conducted twice, considering the sampling points based on the distance between the dug wells and the shrimp paste production area being less than 10 meters, and due to the absence of proper wastewater disposal systems at the shrimp paste production site. From the results of the examination of the physical and chemical water quality around the shrimp paste production area in Jor Hamlet, Jor Village, Jerowaru Subdistrict, East Lombok Regency, it was found that several parameters met the requirements according to the Indonesian Ministry of Health Regulation Number 32 of 2017 concerning the Standard of Environmental Health Quality and Health Requirements for Hygiene, Swimming Pools, Solus Per Aqua, and Public Bathing. Parameters such as temperature, pH, and TDS met the standards. However, the examination revealed that the hardness of the dug well water exceeded the standard in one out of the three sampling points. Specifically, samples A and B met the standard for hardness, whereas sample C did not meet the standard because it exceeded the established quality standard of 500 mg/l.
