Abstract

Abstract. Composite of rice husk and asphalt silica was carried out at a ratio of 1: 0.7; 1: 0.8 and 1: 0.9 and heated at 150oC for 3 hours. The characteristics of the phase structure, microstructure, and functional groups were analyzed using X-ray Diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS) and Fourier Transform Infrared (FTIR), physical properties analysis (density, porosity) and mechanics (compressive strength). The XRD results showed that the phase in asphalt silica composites detected amorphous carbon at 2θ = 18º and amorphous silica with the amorphous silica peak shifted from 2θ = 22º to 2θ = 20º. Microstructure analysis shows that cracks and clusters are bigger with grain sizes of 7,742 µm, 8,495 µm and 10,921 µm respectively, and the sample composition shows percentage of silicon (Si), Oxygen (O) and sodium (Na), respectively. decreases and the percentage of carbon (C), sulfur (S) increases. The results of FTIR show that the functional groups of Si-OH, Si-O-Si and Si-O bonds are decreasing and the functional groups of C-H bonds are increasing. The addition of asphalt causes the value of density increases, the value of porosity and compressive strength decreases.

Abstract

A Water Seal Drainage (WSD) design was made to remove air and fluid from the pleural cavity in the thorax (lung cavity) using a connecting tube or chest tube to maintain the negative pressure of the cavity. Under normal circumstances, the pleural cavity has negative pressure and only a little pleural fluid is filled. Suction pumps have a high pressure with a pressure range of -10 kPa to -80 kPa. The pressure is large enough so that it is not suitable for thorax because it can cause damage to internal organs due to high pressure. WSD specifically for thorax has a low pressure which is below -5 kPa / -40 mmHg. This WSD is equipped with a hand switch, water level and automatic Arduino Uno based exhaust system which has a pressure below -26.6 kPa / -20 cmHg to suction and pressure below -3.4 kPa / -2.6 cmHg to remove liquid from the bottle . The hand switch itself functions as a manual control to make it easier for the user, while the level sensor functions as a safety level for fluid levels in the tool and also an automatic fluid disposal system so that it is more efficient.

Abstract

Infant warmer is one of the tools used to provide comfort and warmth to newborns, where the baby needs a temperature that is in accordance with the temperature in the mother's womb, which is between 34ºC - 37ºC. This tool is made so that a newborn baby can feel the temperature outside the mother's womb will be the same as the temperature that is in the mother's womb. Until now, infant warmer still has to be connected to the PLN nets to activate it. This study aims to create and design infant warmers with DC pemanass equipped with batteries so that when the electricity dies by the PLN this tool can still be used. Data analysis results for power supply output, 12V pemanas input measurement is 11.9V with 0.8% error and 11.8V with 1.6% error, still within the tolerance limit of 5%. The measurement results of temperature comparison between DS18B20 sensor and thermometer, have an average difference of 0.3ºC or 1% error, so that it is still within reasonable limits. This tool has a maximum electric power of 36 Watt which saves power usage around 80%. Compared to a real device where the power needed is around 200 Watts to 300 Watt.

Abstract

[Bahasa]: Pandemi Covid-19 yang melanda seluruh dunia mempengaruhi proses pembelajaran anak sekolah, khususnya di Indonesia. Mereka diharuskan belajar dari rumah secara daring sehingga memerlukan pendampingan dari orang tua. Orang tua dari anak-anak dengan berbagai latar belakang pendidikannya belum optimal dalam melakukan pendampingan belajar ini. Program pengabdian kepada masyarakat ini bertujuan untuk meningkatkan peran Rumah Belajar Garasi dalam menjaga semangat belajar anak-anak di lingkungan RT 04 Jalan Kramat Jaya, Desa Hajimena, Natar, Lampung Selatan. Untuk mencapai tujuan tersebut, tim pengabdian bersama pengelola rumah belajar membuat perangkat media pembelajaran berupa modul dan video yang disebut dengan Garasi kids serta pemberian edukasi kepada warga selaku orang tua. Tim pengabdian juga membuat program pendukung lainnya seperti kegiatan mewarnai dan membuat mozaik untuk anak serta menghadirkan mobil pintar di Rumah Belajar Garasi. Pelaksanaan kegiatan pengabdian ini dilakukan melalui dua pendekatan yaitu edukasi terhadap orang tua dan pendampingan anak mereka dalam proses belajar. Edukasi kepada orang tua ditujukan agar mereka memiliki kemampuan untuk membimbing anak-anaknya saat belajar di rumah. Sementara pendampingan kepada anak ditujukan agar mereka lebih mudah untuk memahami materi pelajaran khususnya bernalar matematika. Hasil pengabdian menunjukkan bahwa penggunaan Garasi kids pada Rumah Belajar Garasi yang disertai keaktifan, semangat belajar, anak dan juga dukungan orang tua mampu meningkatkan kemampuan bernalar matematika anak-anak secara signifikan. Meskipun terdapat sebagian kecil anak-anak berada pada predikat cukup baik dalam menyerap matematika, namun mereka memiliki keunggulan di bidang seni dan kemampuan bekerja sama dengan teman-temannya. Minat baca anak-anak juga tumbuh dengan kehadiran mobil pintar di Rumah Belajar Garasi. Dengan demikian, optimalisasi Rumah Belajar Garasi melalui Garasi kids dapat memberikan kontribusi positif terhadap proses pembelajaran anak di rumah pada masa pendemi. Kata Kunci: anak-anak, Rumah Belajar Garasi, Garasi kids, pandemi Covid-19 [English]: The Covid-19 pandemic has hit the world affecting the learning process of school children, especially in Indonesia. They are required to study from home so they need assistance from their parents. Parents with various educational backgrounds are not optimal in providing this learning assistance.This community service program aims to increase the role of the Rumah Belajar Garasi in maintaining the enthusiasm of children's learning in RT 04 Kramat Jaya Street, Hajimena, Natar, South Lampung. To achieve this goal, we created Garasi kids and educated the society. In addition, other supporting programs were also made, such as coloring, making mosaics, and presenting Mobil Pintar. The implementation of this program was carried out through two approaches, namely educating parents and assisting children in learning. Education for parents is intended to guide their children while studying at home, while mentoring children is targeted to make it easier for them to understand the subject matter. The results of this program show that the use of Garasi kids in Rumah Belajar Garasi accompanied by activeness, enthusiasm for children's learning and also parental support can significantly improve children's mathematical reasoning abilities. Although a small number of children are in a pretty good predicate in understanding mathematics, they have the ability in the arts and work together with their friends. Children's interest in reading also grows with the coming of mobil pintar to the Rumah Belajar Garasi. Thus, the optimization of the Rumah Belajar Garasi through the Garasi Kids makes a positive contribution to the children's learning process at home during the pandemic.

Abstract

The increase in plastic waste caused by population growth and human activities is capable of leading to negative consequences for the environment. The substantial accumulation contributes to environmental pollution since its resilience against microbial degradation poses a significant challenge. Furthermore, the utilization of bioplastics as a biodegradable substitute presents a viable strategy for diminishing reliance on synthetic plastics. Starch emerges as a prevalent primary component in the fabrication of bioplastics, owing to its array of merits including renewability, cost-effectiveness, non-toxicity, and facile degradability. The application of nanomaterials to bioplastics is believed to accelerate the degradation of bioplastics.  Therefore, this study aimed to identify the characteristics of nanomaterial from porang (Amorphophallus muelleri) and bioplastic. The method included the extraction of porang nanomaterial through a specified water-to-porang ratio (2.5:1) followed by sonication (50 W, 75 minutes). The formulation of bioplastics involved the amalgamation of corn starch, porang nanomaterial, and glycerol. In addition, the chemical properties of porang nanomaterials included 41.41% starch content, 13.49% amylose, 7.87% ash, and 2.52% calcium oxalate. The particle size of porang nanomaterials was distributed from 603.7-952.1 nm with an average 722.6 nm crystalline structure containing calcium oxalate. The bioplastic had the form of a thin brown layer with a thickness value ranging from 0.23-0.39 mm. This research was expected to provide new information related to the essential characteristics of nanomaterials from porang and its potential application in solving environmental issues caused by synthetic plastics.
