Abstract

Allium spp. has long been recognized for its diverse therapeutic benefits, particularly as a natural source of antibacterial agents. Various bioactive compounds found in Allium spp., such as allicin, diallyl disulfide, ajoene, and quercetin, have demonstrated significant antimicrobial activity against both gram-positive and gram-negative bacterial pathogens. Research on the mechanisms of antibacterial action of these compounds reveals that they work by disrupting bacterial cell membranes, inhibiting protein synthesis, and interfering with bacterial metabolism. This literature review aims to examine existing studies on the antibacterial potential of Allium spp., reviewing the bioactive compounds involved, their mechanisms of action, and their effectiveness in inhibiting bacterial growth, including antibiotic-resistant pathogens such as methicillin- resistant Staphylococcus aureus (MRSA) and Escherichia coli. The findings of this review indicate that while their effectiveness may vary depending on the specific compound and form of application, Allium spp. shows considerable promise as a natural alternative for combating bacterial infections and addressing the growing issue of antibiotic resistance. This article provides deeper insights into the relevance and potential of Allium spp. in the development of antimicrobial therapies based on natural sources through a literature-based approach.

Abstract

Red chili (Capsicum annuum L.) is a crucial horticultural commodity in Indonesia, necessitating expansion to meet the growing food demands. The formulation of carriers with probiotics is a promising solution for improving red chili growth. This study examines how the combination of carriers containing bacteria and Trichoderma from the intestines of Hermetia illucens larvae affects the growth of red chili cultivar Lembang-1. The research method used a Randomized Block Design (RBD) with six treatments. The treatment consisted of a group with the addition of a kaolin carrier with bacteria and Trichoderma (BTrK), a talc carrier with bacteria and Trichoderma (BTrT), a zeolite carrier with bacteria and Trichoderma (BTrZ), and a control group without a carrier (KtC), a positive control (K(+)), and a negative control (K(-). The Least Significant Difference (LSD) test showed that the addition of carriers affected increasing plant height and the number of branches compared to the negative control. Specifically, BTrK demonstrated the highest number of leaves and branches. The result concluded that adding carriers with probiotics from the intestine isolate of BSF larvae contributes to the improved growth of red chili. The implementation of carrier addition with probiotics is considered to be a sustainable strategy in agriculture.

Abstract

Cellulolytic bacteria can produce cellulase enzymes, which allow them to degrade cellulose into simpler chemicals while using it as a growth substrate. These bacteria have drawn a lot of interest due to their unique properties and potential uses, such as in agriculture and the food industry. Soil is one of the habitats of cellulolytic bacteria. This study aims to determine the potential and screening of cellulolytic bacterial isolates. Cellulolytic bacteria were isolated from soil samples and cultured using selective Carboxyl Methyl Cellulose (CMC) media. Five purified isolates were collected, and their cellulase enzyme activity was qualitatively assessed using the Congo red test. Isolated bacteria code Area Jalan Setapak (AJS1) produced a higher clear zone index and will be used for further testing. Quantitative analysis of isolate AJS1 revealed its highest enzyme activity after ten minutes of incubation, with 0.0049 U/mL unit activity and 0.018 U/mg specific activity. Based on morphological and biochemical characteristics, isolated AJS1 was identified as Corynebacterium spp.

Abstract

The amount of fatty acids added is critical in creating starch-lipid complexes, which can affect their formation and properties. To use the complex to stabilize oil-in-water emulsion systems, this study intends to assess the effects of fatty acid concentrations on the effectiveness of starch-lipid complex formation and the properties of the resulting complexes. Ultrasonication was used to produce starch-lipid complexes from sago starch with different fatty acid contents (10, 12.5, 15, 17.5, and 20%) for the study. The results demonstrated that adding fatty acids up to 15% concentration significantly improved the water absorption capacity (WAC). In contrast, increasing the complexing index (CI), relative crystallinity (RC), oil absorption capacity (OAC), and contact angle of sago starch-lipid complexes. When the concentration of fatty acids was raised over 15%, the properties of the starch-lipid complex did not change considerably. A concentration of 15% with CI 67.07%, RC 37.94%, WAC 1.352 mL/g, OAC 1.370 mL/g, contact angle 70.82 °, emulsion capacity 36.72%, and emulsion stability 35.80% was shown to be the optimal amount of fatty acids for the production of sago starch-lipid complex. Emulsion stability and capacity can be maintained using a sago starch-lipid complex with an ideal fatty acid concentration of 15%.

Abstract

Sungai Opak adalah salah satu sungai utama yang mengalir di Provinsi DIY dan merupakan habitat bagi reptil seperti kura-kura, kadal dan ular. Environmental DNA (eDNA) merupakan metode yang lebih efisien untuk identifikasi spesies dibandingkan metode konvensional yang memiliki beberapa kekurangan. Tujuan penelitian ini adalah mengetahui keanekaragaman reptil di Hulu Sungai Opak dengan menggunakan metode sampling eDNA. Sampel air diambil dari bagian hulu Sungai Opak, kemudian dilakukan filtrasi, ekstraksi dan preservasi DNA, kemudian dilanjutkan PCR dan elektroforesis, sequencing, serta analisis bioinformatik. Hasil analisis eDNA menunjukkan adanya 6 spesies kura-kura dan 33 spesies ular. Metode eDNA dapat menunjukan hasil yang presisi dalam identifikasi sampel ke tingkat spesies, walaupun masih terdapat false positive dan false negative. Penggunaan eDNA metabarcoding dalam identifikasi keanekaragaman jenis reptil di hulu Sungai Opak dapat dilakukan secara cepat namun kurang efektif. Hal tersebut disebabkan oleh kontaminasi eDNA, kurang spesifiknya target sekuens dan primer untuk monitoring reptil, serta database referensi yang belum lengkap untuk reptil yang habitatnya di dalam dan sekitar perairan sungai di Indonesia.

Abstract

Avocado seeds (Persea americana Mill.) are known to possess various pharmacological properties, including notable anticancer potential. While preliminary studies have reported the cytotoxic effects of avocado seed extracts on breast cancer cells, there is still a lack of comprehensive research exploring the underlying molecular mechanisms responsible for these effects. This study explores bioactive compounds found in avocado seeds as potential agents targeting estrogen receptor alpha (ERα), a key biomarker in breast and cervical cancers. The investigation employs a range of computational approaches, including the Lipinski Rule of Five, ADME/Tox predictions, pharmacophore screening, and molecular docking analysis. Of the ten tested compounds, seven passed the Lipinski Rule of Five. ADME/Tox analysis revealed that most compounds exhibited adequate human intestinal absorption (HIA), poor blood-brain barrier (BBB) penetration, moderate Caco-2 permeability, and good plasma protein binding (PPB), while some were predicted to be mutagenic or carcinogenic. Pharmacophore modeling yielded an AUC of 0.87, with procyanidin B scoring 45.09 as a hit compound. Molecular docking revealed catechin, hyoscyamine, and atropine had the lowest Gibbs free energy (-5.15, -0.10, -0.07 kcal/mol). Among the compounds, catechin in avocado seed shows the highest potential for development as an ER-targeted anticancer agent.

Abstract

Red chili (Capsicum annuum L.) is one of the essential vegetable commodities in Indonesia. Nevertheless, the production of red chili is affected by disease due to fungal infection. Previous research showed that the consortial formulation of bacterial and Trichoderma without a carrier from Black Soldier Fly (Hermetia illucens) larva gut enhanced the disease resistance of red chili. Regardless, the research has not overcome several diseases caused by fungal infection. This study aims to analyze the effect of adding kaolin, talc, and zeolite as carriers with bacterial and Trichoderma consortia from BSF larval gut on the disease resistance of red chili caused by fungal infection. This experimental study was carried out in a randomized block design. The treatments were consortial of bacterial and Trichoderma + carrier kaolin (BTrK), talc (BTrT), zeolite (BTrZ), positive control of consortial without a carrier (K+(1)), positive control of inorganic treatment (K+(2)), and negative control of plants without treatment (K(-)). The results were analyzed by calculating disease incidence (DI) and severity intensity (SI) scores to determine disease resistance. New findings prove that BTrK enhanced resistance to fungal infection, namely cercospora leaf spot, leaf rust, and powdery mildew. BTrT formulation enhanced resistance to symptom severity. The study concluded that carrier formulation enhanced the resistance of red chili.

Abstract

Gastropoda air tawar merupakan makrozoobenthos yang memiliki peran penting bagi makhluk hidup, salah satunya dijadikan sebagai konsumsi makanan bagi manusia ataupun sebagai pakan ternak bagi hewan. Selain memiliki manfaat, beberapa jenis gastropoda air tawar menjadi hospes perantara untuk menyempurnakan siklus hidup bagi cacing Trematoda yang dapat menyebabkan penyakit bagi manusia ataupun hewan yang memakannya. Penelitian ini bertujuan untuk mengetahui keanekaragaman gastropoda air tawar dan menganalisis adanya cacing Trematoda yang ditemukan di Situ Gede dan Situ Cibeureum Kota Tasikmalaya. Metode yang digunakan yaitu survei dengan pendekatan kualitatif. Teknik analisis data menggunakan beberapa indeks ekologi diantaranya kelimpahan kumulatif, kelimpahan relatif, indeks dominansi, indeks keanekaragaman Shannon-Weiner, indeks keseragaman, dan prevalensi cacing Trematoda. Berdasarkan hasil penelitian yang diperoleh di Situ Gede terdapat enam jenis gastropoda air tawar dan dua jenis cacing Trematoda, sedangkan di Situ Cibeureum hanya terdapat tiga jenis gastropoda air tawar dan satu jenis cacing Trematoda, telur serkaria dan redia. Terjadinya perbedaan jumlah gastropoda air tawar disebabkan oleh beberapa faktor lingkungan yang mempengaruhi keanekaragaman gastropoda air tawar yaitu suhu, pH, kedalaman air dan substrat. Sedangkan adanya cacing Trematoda yang ditemukan pada gastropoda menyebabkan perbedaan prevalensi cacing Trematoda yang dipengaruhi oleh perbedaan jumlah cacing trematoda dan gastropoda air yang ditemukan serta kondisi lingkungan di masing-masing lokasi penelitian.
