Abstract

Root disease controlling has been a challenge in increasing plant productivity. The soil-borne pathogens become the main concern which mostly infects the root surface. One of the most common soil-borne pathogens is Fusarium oxysporum (Fo). Cayenne pepper (Capsicum sp.) is one of the most abundant commodities and contributes significantly to the economy. This plant is also susceptible to Fusarium wilt infection. The use of endophytic fungi as biocontrol agents is an alternative against soil-borne pathogens, one of which is Trichoderma spp. fungi. This study aims to determine the effectiveness of various spore densities of Trichoderma spp. against the pathogen Fo. The research was conducted through an in vitro study by antagonistic testing between spore suspensions of Trichoderma spp. (103, 105, and 107 spores/mL) with Fo. The results showed the density of 107 spores/mL gave the highest percentage of inhibition (54.59%) compared to spore density of 103 (35.27%) and 105 spores/mL (44.44%). The spore density of 107 spores/mL gave a significant difference in response to the density of other spores according to the BNT test at a significance level of 5% and was able to inhibit the growth of Fo more than 50%. The results of this study are expected to be a reference for the formulation of Trichoderma spp. which is ideal for controlling Fo pathogens in the fields.

Abstract

Increased water pollution due to industrial, household, and agricultural waste has triggered the need for environmentally friendly technologies for water purification. Eco-enzyme, a solution fermented from various kinds of fruit and vegetable kitchen waste with the addition of sugar and water is recognized to have anti-bacterial and anti-fungal properties effective in decomposing toxic substances and improving water quality. Utilization of waste enzymes is emerging as a viable strategy to treat contaminated water as well as organic fertilizer in the cultivation of family medicinal plants. This training activity on eco-enzyme making and pouring was carried out in the framework of community service activities and the 2024 eco-enzyme festival. Training on making eco-enzymes was carried out using socialization and demonstration methods. Then the finished eco-enzymes were poured into the river behind the campus of 'Aisyiyah University Yogyakarta and watered in the cultivation of Family Medicinal Plants in Sidoagung village, Godean sub-district, Sleman. Based on the evaluation of the activity, participants were very enthusiastic about understanding new knowledge and were able to practice the results of making eco-enzymes. In addition to creating a clean environment, pouring eco-enzymes into the river reduces the contamination of pollutants. In addition, the application of eco-enzymes to the cultivation of family medicinal plants can function as a liquid organic fertilizer that fertilizes the soil and optimizes plant growth.

Abstract

Ulkus diabetikum merupakan komplikasi kronis diabetes melitus yang rentan mengalami infeksi oleh bakteri seperti Staphylococcus aureus dan Escherichia coli . Resistensi terhadap antibiotik mendorong pemanfaatan alternatif antibakteri dari bahan alam, salah satunya adalah tanaman pare belut ( Trichosanthes cucumerina ). Buah tanaman ini diketahui mengandung senyawa aktif seperti flavonoid, alkaloid, tanin, dan saponin yang memiliki aktivitas antibakteri. Penelitian ini bertujuan untuk mengetahui efektivitas antibakteri ekstrak buah pare belut terhadap S. aureus dan E. coli penyebab infeksi ulkus diabetikum. Desain penelitian ini adalah eksperimen in-vitro dengan pendekatan post-test only, menggunakan metode Kirby-Bauer. Ekstrak diuji pada konsentrasi 12,5%, 25%, dan 50%, disertai kontrol positif (Gentamisin dan Siprofloksasin) serta kontrol negatif (Aquades). Zona hambat digunakan sebagai indikator aktivitas antibakteri. Hasil menunjukkan bahwa ekstrak buah pare belut lebih efektif terhadap S. aureus (kategori intermediet) dibandingkan E. coli (kategori resisten), dengan peningkatan daya hambat seiring peningkatan konsentrasi. Temuan ini menunjukkan potensi ekstrak sebagai antibakteri alami, meskipun efektivitasnya belum menyamai standar antibiotik. Perbandingan dengan bagian lain dari tanaman pare belut seperti biji, daun, dan batang menunjukkan zona hambat yang lebih besar. Penelitian lanjutan disarankan dengan konsentrasi di atas 50% atau kombinasi antarbagian tanaman untuk meningkatkan efektivitas antibakteri.

Abstract

ABSTRACT The use of chemical-based disinfectants such as sodium hypochlorite (NaOCl), although effective, poses health and environmental risks. This study aimed to evaluate the antibacterial activity of ethanol extracts of betel leaf (Piper betle L.) and citronella leaf (Cymbopogon nardus) as natural disinfectant alternatives against Staphylococcus aureus. A laboratory experimental design with a post-test only control group was employed. The antibacterial test was conducted using the disc diffusion method with 90% ethanol extracts. Results showed that the bioactive ethanol-derived extract of Piper betle leaves exhibited a quantifiable microbial growth suppression zone with a linear spatial extent of 12 mm, while citronella leaf extract produced 11 mm. The positive control (NaOCl) showed inhibition zones of 32–40 mm, whereas the negative control (distilled water) showed no inhibition. Mann-Whitney statistical test revealed a significant difference between treatments (p<0.05). Betel leaf extract demonstrated greater antibacterial effectiveness compared to citronella. However, both extracts showed lower efficacy than the positive control. A key limitation was the use of distilled water as a diluent, which may have reduced the solubility of non-polar active compounds. Future research is recommended to use more compatible diluents (e.g., low-grade ethanol or DMSO) and assess quantitative indices comprising the Minimum Inhibitory Concentration (MIC), which defines the sub-inhibitory limit for microbial growth suppression, and the Minimum Bactericidal Concentration (MBC) for more detailed quantitative analysis. Keywords: Disinfectant, Betel Leaf, Lemongrass Leaf, Antibacterial Activity Test.  ABSTRAK Penggunaan disinfektan berbahan kimia seperti natrium hipoklorit (NaOCl) meskipun efektif, memiliki efek samping terhadap kesehatan dan lingkungan. Fokus investigasi ilmiah ini diarahkan pada pengujian tingkat efikasi bioaktivitas antibakteri yang dimanifestasikan oleh fraksi ekstraktif dari folium Piper betle L. melalui proses pelarutan menggunakan etanol sebagai pelarut polar dan daun serai wangi (Cymbopogon nardus) sebagai alternatif disinfektan alami terhadap Staphylococcus aureus. Skema metodologis yang diimplementasikan terdiri atas simulasi eksperimental berbasis laboratorium, dengan pengaturan desain post-intervensional yang mengadopsi kerangka control group tanpa prosedur pra-intervensi pengukuran. Uji dilakukan terhadap ekstrak etanol konsentrasi 90% dengan mengaplikasikan protokol uji difusi berbasis cakram sebagai metode analitis, observasi eksperimental merefleksikan terbentuknya area inhibisi oleh senyawa bioaktif hasil ekstraksi etanol daun Piper betle dengan ukuran linear ekuivalen sebesar 12 mm, sedangkan ekstrak serai wangi 11 mm. Kontrol positif (NaOCl) menunjukkan zona hambat 32–40 mm, sementara kontrol negatif (aquades) tidak menunjukkan zona hambat. Uji Mann-Whitney menunjukkan perbedaan signifikan antar perlakuan (p<0,05). Ekstrak daun sirih terbukti lebih efektif dibandingkan serai wangi dalam menghambat pertumbuhan S. aureus. Namun, efektivitas kedua ekstrak masih di bawah kontrol positif. Keterbatasan utama penelitian ini adalah penggunaan aquades sebagai pelarut pengencer yang dapat menurunkan efektivitas senyawa non-polar. Penelitian lanjutan disarankan menggunakan pelarut yang lebih sesuai dan melakukan uji MIC serta MBC untuk data kuantitatif.  Kata Kunci: Desinfektan, Daun Sirih, Daun Serai Wangi, Uji Aktivitas Antibakteri

Abstract

Salak fruit is a tropical fruit spread across Southeast Asia and can potentially be a source of natural yeast by processing fruit yeast water. Salak fruit is known to be rich in carbohydrates, making it a potential natural habitat for microbial communities, especially yeast. This research aims to optimize the growth of yeast in the salak yeast water system by varying the sugar concentration treatment, the composition of the amount of fruit flesh, and the fermentation time, as well as identifying the yeast in the salak yeast water. The method used is to count the number of yeast colonies using the Total Plate Count method. The most optimal treatment results are then tested for pH, total sugar, alcohol, isolation and yeast identification. The research results showed that the composition of salak meat was 30%, adding 1% sugar, and fermentation for 6 days resulted in the most optimal growth of the microbial community with an amount of 3.1×10⁶ cfu/ml. The pH test showed a result of 3.01, the alcohol content, namely ethanol, was 0.066855%, no methanol was detected, the total sugar test result in the yeast water was 2.08%, and it was identified in the yeast water that there were Hanseniaspora opuntiae and Candida sorboxylosa. The results show that salak yeast water (Salacca edulis Reinw cv Pondoh) can be used as a yeast water product to ferment food.
