Abstract

Paduan Al 6061 diproses canai dengan reduksi 50%, 60% dan 70% selanjutnya di aging pada temperatur 2000C selama variasi waktu 1800, 3600, 5400, 7200 dan 10800 detik. Analisa microstruktur dan sifat mekanik dilakukan dengan optikal mikroskop dan Brinell Hardness Test (HBN). Bentuk mikrostrukutr menunjukan bahwa butiran memanjang setelah canai berubah menjadi berbentuk equaxial. Analisa XRD menunjukan hadirnya fase ke dua Mg2Si dan Al2FeSi nampak dalam peak XRD setelah canai dan aging. Hal ini nampak bahwa kekerasan meningkat dengan meningkatnya waktu aging dan menurun setelah aging selama 7200 detik. Nilai kekerasan tertinggi dicapai sebesar 121 HBN pada sampel yang direduksi 70% dan ading selama 7200 detik.Hal ini menjadi alasan bahwa kekerasan yang tinggi akibat hadirnya fraksi fase kedua setelah aging meningkat.

Abstract

Wabah Demam Berdarah Dengue (DBD) masih menjadi masalah kesehatan masyarakat di Indonesia khususnya di Palangka Raya karena hingga saat ini masih di temukan kasus DBD. DBD ditularkan melalu gigitan nyamuk betina, sehingga mengidentifikasi tempat perindukan nyamuk sangatlah penting untuk menekan penularan penyakit ini. Habitat nyamuk memegang peranan penting dalam menentukan kepadatan larva, hingga perkembangan nyamuk dewasa. Penelitian ini bertujuan mengidentifikasi tempat perindukan larva nyamuk yang sering terabaikan. Penelitian ini bersifat observasional dan survei jentik dilakukan pada tujuh titik lokasi di area Universitas Palangka Raya pada tahun 2024. Hasil pengamatan menunjukkan bahwa beberapa tempat perindukan larva nyamuk yang sering diabaikan yaitu vas bunga, genangan air dan sampah wadah plastik. Jenis larva nyamuk yang di temukan yaitu Aedes aegypti dan Aedes albopictus, kedua nyamuk ini berperan pada penularan DBD. Wadah perkembangbiakan potensial yang ditemukan di lokasi penelitian menekankan bahwa pentingnya kepedulian dari setiap individu di permukiman dalam pengendalian vektor ini.

Abstract

This is a new author guidelines and article template of Manhaj: Jurnal Penelitian Vectors are insects, rodents, birds, or other animals that can carry disease pathogens. The most common vectors are blood-sucking insects, such as mosquitoes and ticks. Vector-borne diseases occur in animals and humans. However, animals can sometimes carry harmful germs that can spread to humans and cause diseases – these are known as zoonotic diseases. Zoonotic diseases are caused by harmful germs such as viruses, bacteria, parasites, and fungi. This service aims to increase public knowledge about vector bioecology and disease-carrying animals so that the community can carry out appropriate control independently. The activity method is in the form of material delivery, answers, and tests. The results of the pre-test showed that 75% of participants did not understand that what was a vector and 50% of participants did not know the type of vector. 56.25% of participants did not know that rats played the role of disease carriers. The results of the post test showed that 100% of the participants knew about the vector and the animal that carried the disease.

Abstract

Vector-borne diseases are a diversified group of diseases, caused by various pathogens transmitted by rats and arthropod vectors, such as mosquitoes, ticks, and flies. Previous research shows that cases of infectious diseases in Islamic boarding schools/orphanages are found, including dengue, scabies and pediculosis. Some Islamic boarding schools have poor environmental conditions, including toilets, damp and closed dormitories, poor ventilation and lighting, and poor environmental sanitation. Student behavior towards cleanliness and maintaining health is considered to be lacking. Through this service, it is hoped that residents at LKSA/Panti Asuhan Darul Tazkiyah can maintain personal cleanliness and residence so as to reduce the population of vectors and disease-carrying animals in the settlement. The activity was carried out through the method of socialization and two-way discussion. Scouts were given at the beginning of the activity to measure the level of knowledge of participants about vectors and disease-carrying animals. The results of the questionnaire showed that 94% of the participants did not have knowledge about the bioecology of vectors and disease-carrying animals. After the socialization and discussion stage, it can be concluded that participants understand the bioecology of each type of vector (flies, cockroaches, mosquitoes) and disease-carrying animals (rats).

Abstract

Mosquitoes are insects that play a role in the balance of the ecosystem. However, some species of mosquitoes are detrimental because they act as disease carriers (vectors) for humans and animals. The increasing mosquito population is feared to have the potential to become a vector, prompting various efforts to reduce the population, including the use of biopesticides. This article aims to analyze and visualize the research trends on b biopesticides in mosquito control over the past 19 years and to identify potential research topics related to biopesticides for future studies. The methodology used in this article involves a literature review conducted through Publish or Perish and bibliometric analysis using the VOSviewer databases, which collectively encompass 1000 papers. Assessing scientific research progress is crucial for formulating goals and rationalizing future efforts. Based on the results of the bibliometric analysis, biopesticides derived from Bacillus thuringiensis, as well as bacteria, fungi, and other types of microbes, have the potential to be researched and developed as mosquito vector control biopesticide products. Microbial pesticides obtained from actinomycetes, Bacillus thuringiensis (Bt), B. sphaericus (Bs), Lysinibacillus sphaericusand, Saccharopolyspora spinosa, Wolbachia and many other microorganisms are reported as environmentally friendly alternatives for mosquito control.

Abstract

The skin is the outermost layer of tissue that has the function of covering and protecting the surface of the human body. Unhygienic skin will trigger skin infections caused by various microorganisms. One of them is bacteria. Hanjuang merah (Cordyline fruticosa) is a type of plant that is often used as a traditional medicine, especially for the Dayak community. However, research on the use of the Cordyline fruticosa plant in producing liquid body wash formulations that are efficacious as antibacterial against Staphylococcus aureus has not been carried out so far. The purpose of this study is to identify the potential of Cordyline fruticosa as a formulation of liquid body wash formulations and to find the effectiveness of Cordyline fruticosa in inhibiting infections caused by S. aureus bacteria made in the form of liquid body wash. The method used in the extraction is maceration and the manufacture of liquid body wash according to the formulation that has been made, while the disc diffusion method with concentrations of 5% (F1), 10% (F2), and 15% (F3) is used in antibacterial tests. Liquid body wash preparations with the largest inhibitory zone level at a concentration of 15% (F3). The concentration of 15% (F3) is effective in inhibiting the growth of S. aureus bacteria which is characterized by the formation of an inhibition zone around the disk.

Abstract

Many children today face difficulties in learning the Quran, mainly due to a lack of interest, which hampers knowledge retention. Interest is crucial in the learning process, and without it, students struggle to absorb information. To address this issue, Raudlatul 'Ulum Al-Qur'an Education Park implemented an extracurricular program to foster greater engagement and enthusiasm for learning. This research investigates the background, implementation, and impact of these activities. Using a qualitative case study approach, data were collected through observations, interviews, and documentation. The findings reveal that extracurricular activities, held on weekends and in line with the institution’s mission, effectively increased students’ interest in learning. This resulted in greater enthusiasm and diligence, helping students overcome initial boredom and laziness, while improving their Quran recitation and learning experience.
