Abstract

Riparian zones provide ecosystem services depending on the quality of riparian vegetation and vegetation health. The role of riparian vegetation was determined by the total cover, cover structure, vegetation cover quality, and channel alteration of the riparian zone. Vegetation health was to determine the condition of the riparian zone of the Amprong river. In determining the quality of the riparian zone and the quality of the vegetation, it is done by observing the riparian zone of the Amprong river. The results of field observations were analyzed using the QBR index. Vegetation quality was also observed using the Normalized Difference Vegetation Index. The quality profile of the Amprong river riparian zone is in the medium category, while stations 4.2 and 4.3 are in a good category. The good category is obtained from the high total cover dam cover structure value. Meanwhile, the low QBR value is caused by the value of disturbance in the riparian zone in the form of agricultural activities, community settlements, garbage, land conversion to permanent buildings in the riparian zone. The size of the tree canopy at several stations has an impact on the QBR index value. Vegetation connectivity to rivers also helps in maintaining the quality of the riparian zone. Vegetation health on a scale of 0.012 to 0.371 indicates that the sampling site is in good condition. However, this condition will worsen if there is pressure from human activities. Sustainable management is needed by improving the quality of vegetation and reducing disturbance to the riparian zone.

Abstract

Kacang Koro Benguk (Mucuna pruriens D.C.) merupakan tanaman yang menghasilkan bahan obat-obatan yang mengandung senyawa metabolit sekunder, salah satumya L-DOPA. Senyawa ini dapat digunakan untuk mengobati gangguan syaraf, mengobati bisa ular, menambah berat badan dan kekuatan otot, serta sebagai obat cacing pada manusia. Penelitian ini bertujuan untuk menganalisis Kacang Koro Benguk (Mucuna pruriens D.C.) secara In Silico dan mendetekasi adanya senyawa L-DOPA dalam spesies Kacang Koro Benguk (Mucuna pruriens D.C.) menggunakan Spektrometri UV-VIS. Metode yang digunakan yaitu metode deskriptif dan data diolah secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa pada analisis In Silico diketahui bahwa pada spesies Kacang Koro Benguk (Mucuna pruriens D.C.) pada bagian biji dan daun mengandung senyawa L-DOPA dan memiliki struktur molekul C9H11NO4, sedangkan untuk deteksi senyawa L-DOPA menggunakan Spektrometri UV-VIS terdeteksi bahwa Kacang Koro Benguk (Mucuna pruriens D.C.) mengandung senyawa L-DOPA dengan panjang gelombang 462 nm dengan absorbansi pada biji dan daun 2.210 dan 1.171. Kesimpulan dari penelitian ini adalah untuk 20 gram biji koro benguk menghasilkan 1.105 ppm, sedangkan untuk 2 gram daun koro benguk menghasilkan 0.5855 ppm.

Abstract

ABSTRACT The problem of students who live in dormitories often experience itching due to the transmission of scabies disease caused by the Sarcoptes scabiei mite, poor sanitation environments, such as hanging dirty clothes and bedding which serve as preferred living habitat other than in human skin. Scabies mites can survive 2-3 days in the external environment of the body, especially on fabrics such as clothes, towels, and mattresses. The personal hygiene of students and the habits of students do not apply Clean and Healthy Living Behavior, such as the habit of littering. Toilets are poorly maintained and do not wash their hands when consuming snacks; even allowing clogged drains can cause puddles at risk of falling due to slippery floors causing accidents for students, even though the management of the boarding school has given directions and appeals to students, but the application is still low. The method of implementing training activities is carried out by means of active interaction, active discussion, and role play with students and direct practice of waste treatment using a modified model of photochemical technology and a rapid sand filter. Increasing the understanding of students managerially using the herbal game traffic method approach is expected to be able to increase awareness and sensitivity in solving these problems. The results of the analysis of students' knowledge can understand that the cleanliness of clothes, towels, and tools can affect the transmission of scabies. The level of understanding of students is 0.43%. In PKM training activities, there are 98% of students who have increased their understanding of healthy and nutritious nutrition and can be developed in Islamic boarding schools as healthy snacks, while the practice of herbal games is still a model for problem recognition, and herbal solutions are said to be rarely applied by 40% to prevent scabies, both using herbal preparations and the application of clean and healthy living behaviors.

Abstract

Pomegranate is one of the most potential natural resources due to its various compounds, especially in black pomegranate skin. Pomegranate peels are often considered as unusable residue. However, black pomegranate peels have high potential phenolic content and antibacterial properties than other types of pomegranates. This study aims to analyze the total phenolic content and test the antibacterial activity of black pomegranate peel as an antibiotic agent. The method used on the total phenolic content is Folin-Ciocalteau method with UV-VIS Spectrophotometer. Meanwhile, the antibacterial activity test was carried out by the diffusion method with MHA and MHB media against Gram-Positive and Gram-Negative bacteria, namely Eschericia coli and Staphylococcus aureus and positive control using apmhicilin and chloramphenicol. Bacteria were streaked on sterile solid media using sterile cotton buds. The results obtained on the total phenolic content of black pomegranate skin resulted in 90.89 μg GAE/mL sample. Meanwhile, the antibacterial properties obtained the largest diameter of the inhibition zone on Eschericia coli and Staphylococcus aureus respectively, namely 23.4 ± 0.19 and 21.7 ± 0.35 mm. The results showed that black pomegranate peel contributes significantly to environmentally friendly antibacterial properties and can be an innovation in antibiotic development. These findings, open up new opportunities in the formulation of natural antibiotic products that are effective and safe for humans.
