Abstract

Penelitian ini merupakan studi awal untuk mengeksplorasi potensi probiotikBakteri Asam Laktat (BAL) dari dangke, makanan tradisional dari susu sapi dikabupaten Enrekang. Probiotik adalah mikroorganisme hidup yang bila diberikandalam jumlah yang cukup memberikan manfaat kesehatan pada inangnya. Salahsatu mikroorganisme yang berpotensi menjadi probiotik adalah bakteri asam laktatyang banyak ditemukan pada susu. Penelitian ini bertujuan untuk mengetahuibakteri asam laktat yang terdapat pada dangke dengan bahan dasar susu sapi.Isolasi BAL menggunakan media selektif de Man Rogosa Sharpe Agar. BAL akanmenunjukkan zona bening pada medium MRS setelah penambahan indikatorCaCO3 dan diinkubasi selama 24 jam. Seleksi dilakukan dengan mengamatimorfologi sel, pewarnaan Gram, dan uji biokimia. Hasil penelitian menunjukkanbahwa isolat yang diperoleh terdiri dari dua spesies yaitu Lactobacillus fermentumdan Lactobacillus acidophilus yang menunjukkan gram positif dan katalasenegatif.

Abstract

Cendawan Rhizosfer membantu pertumbuhan tanaman melalui berbagai mekanisme seperti peningkatan penyerapan nutrisi, sebagai control biologi terhadap serangan patogen, dan juga menghasilkan hormon pertumbuhan bagi tanaman. Pentingnya populasi mikroorganisme di sekitar Rhizosfer adalah untuk memelihara kesehatan akar, pengambilan nutrisi atau unsur hara, dan toleran terhadap stress/cekaman lingkungan pada saat sekarang telah dikenal.

Abstract

Mycorrhizae are typical structures found in a plant's root system found symbiotic mutualism between fungi (myces) and roots (rhiza). Mycorrhizae have an essential role for plants because they can increase water and nutrient uptake, especially phosphorus absorption. The purpose of this study was to determine the mycorrhizal genera on the roots of parring bamboo plants (Gigantochloa atter) in Sabantang Hamlet, Toddopulia Village, Tanralili District, Maros Regency because there is no scientific information regarding this issue. This research was conducted with the wet filter method or sieving. The isolation of spores from the rhizosphere of Gigantochloa atter samples was carried out by referring to the pouring method and wet sieving using a stratified filter set. Staining techniques were used to observe the colonization of arbuscular mycorrhizal structures in the roots of the sample plants. The results showed that 27 spores were found, consisting of 15 spores of the Glomus genera, three spores of the Gigaspora genera, and nine Acaulospora genera. Observation of the root structure has not shown the presence of vesicular and arbuscular. However, only hyphae and spore structures were found because the mycorrhizal hyphae in Gigantochloa atter have not yet reached the infection stage to form arbuscular or vesicular structures

Abstract

This study reveals that the super-intensive shrimp farming waste from Punaga can be used as a source of electricity through a bio-electrogenic process based on indigenous potential bacteria from the waste. The results show that four types of potential bacteria isolated from the super-intensive shrimp farming waste can each produce a significant average power density. Bacteria isolate D (Bacillus sp) showed the highest electrogenic potential with an average power density of 38.55±0.87 mW/m², followed by bacteria isolate B (Pseudomonas sp) with an average power density of 34.72±2.80 mW/m², bacteria isolate C (Bacillus sp) with an average power density of 29.90±5.26 mW/m², and bacteria isolate A (Bacillus sp) with an average power density of 25.90±1.69 mW/m². This study shows that the super-intensive shrimp farming waste from Punaga can be utilized as a source of electricity through a bio-electrogenic process using certain potential bacteria, such as Bacillus sp and Pseudomonas sp isolates. The development of waste treatment technology as a source of electricity through the bio-electrogenic process can provide a significant contribution to addressing global energy and environmental issues. This can be considered an implementation of the concept of "khalifah fil tadbir", in which humans act as stewards of the earth, responsible for using natural resources wisely and being accountable for the resulting environmental impacts.
