Abstract

Tujuan penelitian ini untuk mengetahui kelayakan rancang bangun alat peraga mobil remot kontrol berbasis Education for Sustainable Development (ESD) untuk menjelaskan konsep listrik dinamis. Penelitian ini merupakan penelitian rekayasa. Rancang bangun perangkat ini terdiri dari tiga komponen utama yaitu 2 baterai, 2 dinamo, dan stik es krim. Validasi kelayakan alat ditinjau dari aspek ahli materi, ahli media, dan kelayakan alat. Alat peraga diuji oleh 3 dosen, 1 guru, dan 11 teman sejawat dengan menggunakan teknik penyebaran angket. Teknik analisis data pada penelitian ini adalah teknik analisis deskriptif. Berdasarkan hasil perhitungan angket dari ahli untuk uji kelayakan didapatkan rata-rata 87,19% dengan kriteria sangat baik. Sehingga dapat disimpulkan bahwa mobil remot kontrol berbasis Education for Sustainable Development (ESD) sangat layak dijadikan alat peraga fisika untuk menjelaskan konsep listrik dinamis

Abstract

Leachate is residual waste that is exposed to water when it rains. Leachate contains physical, chemical and biological parameters that are dangerous if it enters the canals and residential areas of residents. Many problems will arise if the leachate is not treated and left alone. The purpose of this study was to determine the amount of leachate pollution on the environmental health of settlements at the Bakung final disposal site in Bandar Lampung. This type of research is qualitative research and is presented descriptively. The test sample was taken using the composite sample method (combined place) at three pool points, each of 1.7 liters with a total of 5 liters and homogenized. Samples were analyzed using SNI 8995:2021 and the water quality was assessed using the Pollution Index (IP) method. To find out the health of the environment using interviews with the community around the final disposal site. The results of the analysis showed that the physical and chemical parameters of leachate at Bakung landfill that exceeded the leachate quality standards were TSS (538.33 mg/L), BOD (5382 mg/L), COD (8220 mg/L), Total Nitrogen (91 mg/L). If the leachate is only collected without further treatment, it will result in the leachate entering residential canals and contaminating the well water in the surrounding area and possibly causing health problems such as skin irritation. Toxic environment, water unfit for consumption evenblue baby syndrome in infants and an increased risk of colon cancer.

Abstract

In an effective management system, the importance of human resources is increasing. Employee performance is an essential factor influencing success. In an organization, this is one of the most critical functions of a company. This study aims to determine the variables that affect employee performance and develop a theoretical basis and research model. This study used an associative descriptive quantitative method with a population of 50 respondents drawn into samples using non-probability sampling using saturated sampling / total sampling methods—data analysis techniques using linear regression with the help of SPSS software version 26. The results of this study show that the first hypothesis states that employee performance is influenced by the effectiveness of training, meaning that the better the effectiveness of training, the more improved the employee's performance. Thus, the second hypothesis states that employee performance is influenced by knowledge management, meaning that the higher the knowledge management possessed by employees, the higher the performance of employees. The third hypothesis is that employee performance is influenced by the effectiveness of training and management knowledge that can simultaneously improve employee performance. This research is expected to provide theoretical contributions to the literature in this context, certainly in the context of human resource management.

Abstract

Irrational antibiotic use in the treatment of infectious diseases can result in the emergence of antibiotic-resistant bacterial strains, such as Methicillin Resistant Staphylococcus aureus (MRSA). The purpose of this study is to determine the physical properties of citronella essential oil (Cymbopogon nardus (L.) Rendle) and to assess its antibacterial activity against MRSA. Citronella essential oil was extracted using a water-steam distillation method, yielding 0.5 percent. Citronella essential oil has a specific gravity of 0.904, a refractive index of 1.470, and is slightly soluble in 80 percent ethanol. All of these parameters were in accordance with the Indonesian Standard Requirement (SNI) for Citronella essential oil. The disc diffusion assay was used to test the antibacterial activity of this Citronella essential oil. The result indicated that Citronella essential oil has an activity to inhibit MRSA invitro.
