Edukasi Masyarakat Jatirejo Mojosongo dalam Meningkatkan Perekonomian melalui Budidaya Maggot Berbasis IoT untuk Pengolahan Sampah Organik

Organic waste makes up the lion's share of solid waste generated by human activities. Therefore, organic waste management efforts are needed to help solve it. One of the efforts that can be made is using BSF larvae to decompose organic waste. BSF larvae or maggots have a high protein and fat content, a chewy texture, and the ability to secrete natural enzymes. BSF females can lay up to 400-800 eggs. After 3-4 days, the eggs will hatch into larvae and consume organic waste, including various types of organic waste such as kitchen, fruits, vegetables, fish, urban, human, and animal waste. The flexibility of BSF larval feed facilitates the cultivation process, and it becomes an ideal insect for decomposing organic waste and becomes a business field because of its fat and protein content. The method of decomposing litter using BSF larvae is quite promising because the opportunities are quite promising, but it is still completely manual. Therefore, IoT-based maggot cultivation, an innovation in maggot cultivation, is needed. IoT design is placed at the maggot breeding stage, with optimal temperature, humidity, and light intensity conditions. This breeding ground is equipped with Arduino, humidity, and temperature sensors to regulate and maintain the best state in each larval breeding process until it becomes a pupa. This design is expected to provide convenience and increase the yield of maggot cultivation.

Public perceptions of government policies to COVID-19: A comparative study in six African countries

The outbreak of COVID-19 has affected countries across the world, including those in Africa. Governments in these countries have implemented various policies to curb the spread of the virus. However, the effectiveness of these policies largely depends on how the public perceives them. This study aims to investigate public perceptions of government policies regarding COVID-19 in six African countries by conducting a sentiment analysis of the public. The motivation behind this study relies in the recognition that a deeper understanding of public perceptions is essential for crafting effective strategies that resonate with the diverse needs and concerns of the population, ultimately contributing to the ongoing global efforts to navigate the complexities of the COVID-19 pandemic. We collected tweets related to COVID-19 and government policies on Twitter's API from March 07, 2020 to February 02, 2022. We performed data processing steps such as tokenization and stop-word removal to clean the data. Next, we used Natural Language Processing (NLP) techniques to classify the sentiment of each tweet as positive, negative, or neutral. The six African countries selected for this study are Nigeria, South Africa, Kenya, Ghana, Rwanda, and Uganda. We collected 134,494 tweets on Twitter accounts and we evaluated policies by countries in three categories: while some countries implemented too strict policies, others implemented strict or relaxed policies. The findings of this study will provide valuable insights into how the public perceived the policies. This is used to advice policymakers and public health officials on enhancing their messaging and policies to combat the spread of COVID-19 effectively. Data showed heterogeneous reactions with negative perceptions, for instance, earlier, different governments implemented face mask and lockdown policies and vaccination policy later. Researchers and policymakers should exercise caution and consider complementary data sources and methods to ensure a more comprehensive and accurate understanding of public perceptions in the context of government policies related to COVID-19; also, investigate how government policies during the pandemic may have affected the environment, such as changes in pollution levels, waste management, and conservation efforts.

Optimization of Methylene Blue Adsorption onto Activated Carbon derived from Pineapple Peel Waste using Response Surface Methodology

This study focuses on the optimization of methylene blue (MB) adsorption onto activated carbon derived from pineapple peel waste (ACPPW) using response surface methodology (RSM). The activated carbon was synthesized via a chemical activation method and characterized using FTIR spectroscopy. The adsorption process was optimized by investigating the effects of three key parameters: adsorbent dosage, initial dye concentration, and contact time. A Central Composite Design (CCD) with 20 runs was employed, and ANOVA was performed to determine the significance of each parameter. The central composite design (CCD) was employed to determine the effect of three independent variables, namely adsorbent dosage (X1), initial MB concentration (X2), and contact time (X3), on the response variable, MB removal efficiency (Y). The optimal conditions for achieving a high adsorption capacity of 98.19 % for methylene blue dye were determined to be an adsorbent dosage of 400 mg/L, an initial dye concentration of 15 mg/L, and a contact time of 12 minutes. The regression equation achieved a high R2 value of 0.9883, indicating a good fit for the experimental data and the model's reliability. These findings provide valuable insights into efficiently utilizing pineapple peel waste as a sustainable source for producing activated carbon with excellent adsorption capabilities for dye removal, thus contributing to environmental sustainability and waste management efforts.

Wet-dry cycle of expansive soil stabilized with fly ash and waste foundry sand on bearing capacity and swelling potential

The behavior of expansive soil, which is sensitive to water, makes it susceptible to moisture content changes, resulting in the soil becoming soft during the rainy season and soil shrinkage during the dry season. This research aims to study the effects of the wet-dry cycle on the bearing capacity and swelling potential of stabilized expansive clay soil using two types of industrial waste, namely Fly Ash (FA) and Waste Foundry Sand (WFS), as soil improvement and industrial waste management efforts. The wet-dry cycle is assumed to represent the changes in the environment due to seasonal variations. The wetting cycle is conducted by immersing the soil samples in water, while the drying cycle is achieved by allowing them to air dry at room temperature. The FA content is set at 9% and the WFS content at 15% by weight of dry soil. The California Bearing Ratio (CBR) test is performed after the completion of the wet-dry cycle, while the swelling test is conducted during the wet-dry cycle. Each sample undergoes one, two, and three cycles of wetting and drying. The results showed that the CBR value increased with the addition of FA and WFS. The CBR value of natural soil is 8.89% while the CBR value of soil+9%FA+15%WFS is 16.02%. During the wetting phase, the CBR value decreases with increasing moisture content. After undergoing the third cycle, the CBR value and development potential tend to remain constant.
