Abstract

This Classroom Action Research aims to improve student learning outcomes by applying the demonstration method to mathematics learning. The research procedure uses Classroom Action Research (CAR) with several cycles. Each cycle includes four stages, namely planning, implementation, observation, and reflection. The research subjects were students of class XII MIA 9 SMAN 10 Padang in the academic year 2018/2019 odd semester as many as 30 people. Data from research results: 33.33% pre-cycle completeness increased in the first cycle completed 63.33%, and increased in the second cycle completed 83.33%. Overall there is always an increase from pre-cycle to cycle II. Thus it can be concluded that: Improving Student Learning Outcomes With the Demonstration Method In Class XII MIA 9 SMAN 10 Padang

Abstract

An Pleural effusion is an excessive accumulation of fluid, blood or water in thepleural cavity which will cause the increase of shortness of breath because of thedecreasing space for lung expansion. One of the efforts to reduce the complaintsof shortness of breath is by insertion of water seal drainage. Water Seal Drainage(WSD) is a medical action performed to remove air or fluid from the pleuralcavity. The patient's ability to breathe effectively is an indicator to release WSD.This study generally aims to determine the effectiveness of diaphragmaticbreathing exercises on the speed of lung expansion in patients with water sealdrainage insertion.The research design was pre experiment with pre test - post test group design.The population in this study were patients with insertion of WSD who wereadmitted to Dr. Muwardi Surakarta Hospital. The sampling technique waspurposive sampling. The number of samples were 16 respondents. To measurelung expansion, the indicator used Peak Expiratory Flow Rate as measured bypeak flow meter. Data analysis used dependent t-test.The results show that there are differences in the speed of lung expansion inpatients with WSD insertion before and after diaphragmatic breathing exerciseswith p-value of 0.0001.Suggestion for nurses to be able to train diaphragmatic breathing exercise inpatients with WSD insertion increase lung expansion so that WSD can bereleased and the risk of infection can be reduced

Abstract

To improve the performance of a biogas Digester, several methods can be employed, one of which is by adding a circulation system [1]. Circulation in the Digester helps distribute the substrate and microorganisms evenly [2], thereby accelerating biological reactions and releasing gas, thus enhancing biogas productivity [3]. The objective of this study is to design and analyze the impact of a circulation system on a biogas Digester during the fermentation of liquid tofu waste and cow manure. The research was conducted in two stages: first, designing the Digester, and second, operating the Digester in two steps. The first step involved batch fermentation for 14 days to condition the degrading microorganisms. The second step involved continuous fermentation for 16 days, operated with a circulation system at varying rates of 0, 30, 60, and 90. The variables studied included digester pressure, CH4 concentration, and COD reduction. The results showed that circulation increased biogas productivity, with the best variation achieved using 90 circulation, resulting in a pressure of 0.19 kg/cm², 58% CH4, and 33.33% COD reduction.
