Abstract

Endophytic microbes are microbes capable of colonizing and symbiotic with plant tissues. Trichoderma has been known as an endophytic fungus with a symbiotic relationship of mutualism including root colonization by helping root growth, nutrient absorption and resistance to stress and pathogens. This study consists of two steps, namely: (1) isolation and identification of Trichoderma, (2) endophytic test of Trichoderma isolate by root staining method and plant root culture. Seven isolates were shown to result in better plant growth and plant roots. Based on plant root culture tests, it was found that all plants contained Trichoderma, but based on T. Koningii and T. Polysporum root staining tests. It cannot be certain to colonize the root tissue of test plants. Based on the test results, Trichoderma has the potential to be a biological fertilizer (Biofertilizer) that can help optimal plant growth and can be applied in agriculture that applies the concept of sustainability.

Abstract

Nowadays plantation has change to more sustainable agricultural system towards effectivity, smart system and not only environmentally friendly but also in sustainability aspects. This study aims to explore Trichoderma as biofertilizer with bioantagonistic ability. The experiment design to test Trichoderma against Fusarium Oxysporum (Wilt Desease) and Thrips (pathogen) in aclimatisation test in tomato and chili plant. The result in antagonistic against Fusarium, T. harzianum B and T. cacao 29 have good inhibitory, namely around 70% of the resistance percentage. While T. Koninggii or T. Pseudokoningii (DT 38) was the weakest. Based on that Trichoderma approved has bioantagonistic ability against Fusarium invasion. But for large scale implementation, formulation and perfection microbial isolate are needed.

Abstract

Thrips is a pathogen insect that commonly attacked crop plant. Tomato and chili are essential crop plant in indonesia. In order to tackle this problem not only environmentally friendly but also in sustainability aspects, bioinsecticide agent are explored. This study aims to explore Trichoderma as endhopytic fungi with bioinsecticide ability. The experiment design to test Trichoderma Thrips in aclimatisation test for tomato and chili plant. The result in controling test against Thrips, T. DT 38 and T koningii was the best resistence while T harzianum B was the worst. This isolate can help slowing the effect of Thrips invasion. Based on that Trichoderma approved has bioinsecticide ability against Thriips invasion. But for effective implementation, formulation and perfection microbial isolate are needed.

Abstract

Lakes are an important part of the inland water system that functions to maintain environmental stability, support biodiversity, and provide ecosystem services such as clean water supply, flood control, and natural recreation space. This study was conducted to analyze the quality of the lake and the lake's carrying capacity for fisheries and tourism facilities. Physical, chemical, biological parameters, and lake fertility index were calculated referring to the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 5 of 2021 concerning Procedures for Issuing Technical Approvals and Operational Feasibility Letters for Environmental Pollution Control. The results of the study found high pollution parameters in BOD, COD, and TDS. Lake Lido is classified as having a fairly high pollution load with a lake with a Eutrophic trophic index so that further analysis is needed for the level of pollution distribution, lake carrying capacity and lake utilization management strategies for sustainable fisheries and tourism activities. Recommended strategy of Domestic Wastewater Treatment Plant is a system which meet the quality standards for domestic wastewater based on Permen LHK No. 68 of 2016, with an integrated system. As environmentally friendly fish farming strategy that is recommended was the use of SMART Floating Net Cages (KJA).

Abstract

Andesite mining activities cause land degradation that requires revegetation efforts for ecosystem restoration. This study aims to evaluate the ecological feasibility of bamboo as an alternative revegetation species for post-mining sites compared to conventional pioneer plants through a systematic literature review. Analysis was conducted on 45 relevant scientific publications from indexed academic databases, focusing on adaptability, soil improvement, erosion control, and contribution to biodiversity. Results show that bamboo has significant advantages in root systems (fine root biomass 1.1-4.5 kg m⁻³), erosion control effectiveness, and carbon sequestration potential (6-13 Mg ha⁻¹ year⁻¹). Bamboo also demonstrates high adaptability to marginal land conditions and provides sustainable economic value through selective harvesting without damaging the root system. Compared to conventional pioneer plants, bamboo provides more stable long-term contributions to post-mining ecosystem restoration. This study recommends the use of bamboo as a primary component in andesite post-mining land revegetation programs in Indonesia.

Abstract

Electricity consumption is increasing, causing fossil fuels to run out more quickly. Various efforts are needed to develop renewable energy, including generating electricity. One of the developments in renewable energy comes from biomass. There are various types of biomass developed, one of which is biomass of microorganisms which carry out metabolic activities by utilizing organic material to produce metabolites which include energy. Microbial fuel cell (MFC) is a technology that produces electrical energy with the help of microorganisms that degrade organic materials through catalytic reactions or bioelectrochemical mechanisms from microorganisms. In this research, bioelectricity produced from MFC was tested using Aspergillus Niger with sugarcane bagasse as a substrate. The voltage value obtained from observations carried out for 15 days obtained a voltage in the range of 1.3-4.2 mV
