Moringa (Moringa oleifera Lam.) is a type of tropical plant that is easy to grow in Indonesia. This plant is classified as a shrub with a height of about 7-11 meters and thrives in the lowlands up to an altitude of 700 meters above sea level. Moringa plants have the potential to increase livestock production, especially used as feed for ruminants. Currently research on moringa is mostly focused on nutritional quality and health value obtained, while research on optimal cultivation of moringa is still very little. In this study, the production of moringa plants grown on soil media was carried out with the addition of manure with different doses and sources on the production of moringa plants. This study used a completely randomized design (CRD) with three treatments and five replications, P0 = 2 kg of soil without fertilizer, P1 = 1 kg of soil and 1 kg of cow manure. P2 = 1 kg of soil and 1 kg of goat manure. The application of organic fertilizer resulted in a significant decrease in the height growth of Moringa plants. On the diameter of the stem, organic fertilizer has a significant effect on increasing the size of the stem diameter. On leaf growth, the application of organic fertilizers did not significantly affect the growth of plant leaves. Types of organic fertilizers that give the best effect are goat feces on plant height, cow feces and goat feces give the best effect on plant stem diameter.

Asbuton is natural asphalt whose use in Indonesia is no stranger. One of the asbuton technologies that has been widely used is pre-mixed asbuton. Pre-mixed asphalt is one type of modified asphalt used in Indonesia. Pre-mixed Asphalt is processed and mixed with Pen 60/70 Asphalt at a factory that meets certain requirements, so that it is equivalent to Modified Asphalt. Premixed Asbuton products have a minimum level of purity of 90%, so they still contain a maximum of 10% fine minerals. This type of processed Pre-mixed Asphalt is the mobile container circulates directly inside the Asphalt Mixing Plant (AMP) boiler without the addition of Asphalt Pen 60/70 to produce Hot Mix Asphalt (Hotmix) which is equivalent to using Modified Asphalt. From the results of testing in the laboratory it was found that the asphalt mixture using pre-mixed asphalt has better technical properties than the conventional asphalt mixture (made using Pen 60/70 asphalt)

The Universitas Pahlawan Tuanku Tambusai (UPTT) campus allows it to become a preferred habitat for mosquitoes while laying their eggs. Aedes sp. is a vector for the spread of Dengue Hemorrhagic Fever (DHF). One way to control dengue fever is to use insecticides. The use of insecticides that are excessive and repeated can have a negative impact, for that we take advantage of the potential of nature as a bioinsecticide. One of them is the lemongrass plant which can be used as a mosquito repellent because it contains substances such as geraniol, methyl heptenone, terpenes, terpenes, organic acids and especially citronella as a mosquito spray. This research is a quantitative research with a pure experimental design. Researchers made observations in the field to collect mosquito larvae, which were then reared in the laboratory. The results of rearing mosquitoes were then treated and analyzed using WHO mosquito mortality standard criteria. Lemongrass plants can be used as bioinsecticides or insect organic insecticides, for example the Aedes sp. Lemongrass plant extract (Cymbopogon citratus) is effective in killing Aedes sp. mosquito larvae. along with increasing concentration in each treatment. The most potent or effective concentration in killing Aedes sp. is a concentration of 20%.

Green building atau bangunan hijau adalah pendekatan dalam merancang, membangun, dan mengoperasikan bangunan yang mempertimbangkan dampaknya terhadap lingkungan dan kesehatan manusia. Berdasarkan itu, perlu diadakannya kajian tentang green building di bangunan Gedung Klinik Universitas Pahlawan, agar diketahui rating atau tingkat penerapan green building di Gedung Universitas Pahlawan. Penelitian ini bertujuan untuk menganalisis penerapan green building dan manfaat yang dihasilkan. Metode penelitian yang digunakan adalah tinjauan literatur dan studi kasus. Dalam tinjauan literatur, berbagai sumber yang relevan seperti jurnal ilmiah, artikel, dan laporan penelitian digunakan untuk memperoleh informasi tentang konsep dan praktik green building. Studi kasus dilakukan di bangunan Gedung Klinik Universitas Pahlawan dengan menganalisis beberapa bangunan Gedung yang telah dibangun dan beroperasi. Menggunakan standar Greenship Existing Building versi 1.1 dari GBCI. Greenship EB 1.1 mempunyai 6 (enam) standar yaitu tepat guna lahan, efisiensi dan pengelolaan energi, pengelolaan air, siklus dan sumber daya material, kualitas udara dalam ruangan dan manajemen lingkungan bangunan. Hasil analisis menunjukkan bahwa penerapan green building masih banyak tidak terpenuhi disebabkan kurangnya tolok ukur yang tersedia. Rekomendasi yang dapat diberikan meliputi penggunaan bahan konstruksi yang lebih ramah lingkungan, penerapan sistem penghematan energi yang lebih efektif, penggunaan teknologi pengelolaan air yang lebih canggih, dan peningkatan dalam pengelolaan limbah.

Perancangan Visual Display Informasi Di Laboratorium Terpadu Universitas Pahlawan Tuanku Tambusai
Lailatul Syifa Tanjung, Resy Kumala Sari, Hanantatur AdeswastotoShow Abstract | Download PDF | DOI: 10.31004/jestm.v3i1.82 | Check in Google Scholar
Hazards can occur anywhere and anytime, including when humans are working in the work environment. Workers often forget that there are dangers threatening around them. The need for invitations to workers to be able to maintain occupational safety and health (K3) at work is an effort that is felt to foster a sense of care for oneself and others to avoid danger. The purpose of this research is to design a visual display of information with an ergonomics approach and visual communication in the integrated laboratory of Pahlawan Tuanku Tambusai University. The ergonomics approach is an approach that utilizes information about the nature, abilities and limitations of humans in designing a work system so that humans can live and work on the system properly, namely achieving the desired goals through the work with ergonomic principles. Meanwhile, the visual communication approach is an approach to the concept of communication and the expression of creative power, which is applied in various visual communication media by processing graphic design elements consisting of images (illustrations), letters, colors, composition and layout. From this research, the results are in the form of calculating the width and height of letters that are good for display design at the integrated laboratory at Pahlawan Tuanku Tambusai University based on an ergonomic approach, good typography types for use in display design and display design based on an ergonomic approach and visual communication.
