Abstract

Despite having a considerable potential area, the optimal utilization of dry land is challenging due to the generally low soil moisture content and fertility of dry land in Indonesia. This is evidenced by the intrinsically low organic matter content in dryland soils. Therefore, this article aims to provide information on the potential application of chicken manure to enhance soil fertility and health or to rehabilitate suboptimal dry lands in Indonesia. The methodology used in this article is qualitative, based on a literature review. One approach to improving the condition of dry land in Indonesia is the application of chicken manure, which acts as a soil conditioner and enhances overall soil fertility and health. The results of the study indicate that using chicken manure on dry land can increase crop production, thereby positively correlating with the profits of dry-land farmers.

Abstract

The utilization of maggot frass from Black Soldier Fly (BSF) larvae (Hermetia illucens Linneus, 1875) has garnered attention in the context of organic farming as a promising alternative to enhance plant growth and development. Maggot frass, a byproduct of the larval digestion process, is rich in essential nutrients such as nitrogen, phosphorus, potassium, and contains beneficial microorganisms for the soil. This study employs a literature review method. Literature sources were obtained from the Google Scholar database using keywords such as "maggot frass", "kasgot", "Black Soldier Fly", and "Hermetia illucens". The articles obtained were then analyzed to gather secondary data. The aim of this research is to explore the potential utilization of maggot frass from BSF larvae in enhancing plant growth and development in the context of organic farming. Research on the utilization of maggot frass has shown significant potential in improving soil fertility and increasing crop productivity. Furthermore, the use of BSF larvae in organic waste management can also significantly reduce waste volume while creating valuable resources for agriculture. By integrating the utilization of maggot frass into organic farming practices, it is hoped that a more sustainable and environmentally friendly agricultural system can be created in the future.

Abstract

This study aims to analyze the morphometric anatomical wings of the fruit fly Bactrocera dorsalis Complex. The species used in this study consisted of 11 (eleven) species. The analysis technique of the wings of Bactrocera dorsalis Complex, i.e. the right wing of each individual was analyzed using Morphometric landmarks with 15 anatomical points. Digital images of wings are scaled in size and scale using Adobe Photoshop CS3 software. The results of anatomical point digitization are processed into MorphoJ software v. 1.06b. Digitization data of anatomical points of wing shape was collected using Generalized Procrustes Analysis (GPA).  The results of the Canonical Variate Analysis (CVA) showed that there was a grouping of each species. The grouping of Bactrocera dorsalis complex wing types is based on the similarity of the percentage of cumulative values of CVA1 and CVA2 tests. Groups B. carambolae, B. minuscula, B. occipitalis, B. papayae, B. floresiae, B. philippinennsis, Bactrocera sp. 23, Bactrocera sp. 25, and Bactrocera sp. 26 grouped because they have similarities in wing venation. The difference in wing venation is found in Bactrocera sp. 27 and B. sumbawaensis because they are far from the group B. carambolae, B. minuscula, B. occipitalis, B. papayae, B. floresiae, B. philippinennsis, Bactrocera sp. 23, Bactrocera sp. 25, and Bactrocera sp. 26.

Abstract

Salmonella is one example of bacteria that can contaminate fishery products. It is one of the bacteria that most commonly infects people through contaminated food and drink. One management to reduce Salmonella in fishery products is using Biofilm. The biofilm mechanism formed from Salmonella typhi type bacteria can be inhibited from several intervention strategies that are able to disrupt and prevent biofilm formation. Green grass jelly leaf extract has antibacterial activity against S. typhi which is indicated by the formation of an inhibition zone due to the activity of flavonoid compounds. denaturing proteins and damaging bacterial cell membranes, flavonoids can also function as antibacterials by forming complex compounds that attack extrinsic proteins and inhibit biofilm formation by inhibiting the expression of icaA and icaD genes. flavonoids form complex compounds against extracellular proteins, which disrupt the integrity of the bacterial cell membrane. It does so by denaturing bacterial cell proteins and damaging the cell membrane beyond repair.

Abstract

This research analyzes the impact of climate change on the vulnerability of coastal areas and small islands in Gili Air, North Lombok. Climate change, including rising temperatures and sea levels, is affecting coastal ecosystems, such as coral reefs which are vulnerable to bleaching and death. This study identifies a trend of increasing built-up land on Gili Air in the 2013-2022 period, which is caused by tourism promotion policies. The impact of this policy causes an increase in the number of tourists and local residents, which then increases the need for tourism supporting facilities. These land cover changes and development pressures increase Gili Air's environmental and economic vulnerability to climate change. These findings emphasize the importance of comprehensive adaptation and mitigation strategies to preserve the sustainability of ecosystems and the livelihoods of local residents.

Abstract

Heavy metal mercury pollution in the environment can have negative impacts on both surrounding ecosystems and human health. Sources of mercury pollution often come from mining activities, particularly from many unlicensed gold mines (PETI) that use the mercury amalgamation method to extract gold. Due to the persistent, bioaccumulative, and toxic nature of mercury, contamination in the soil has increased. One effort to reduce mercury toxicity is the application of absorption methods using phytoremediation plants and compost as regulating factors. The aim of this study is to review sources of information related to the use of phytoremediation plants and the application of compost as remediators to clean mercury (Hg)-contaminated soil. To reduce levels of heavy metal contamination, plants employ five phytoremediation mechanisms: phytoextraction, phytostabilization, rhizofiltration, phyto degradation, and phytovolatilization. Therefore, selecting hyperaccumulator plants that have the ability to accumulate mercury (Hg) at levels 100 times higher than ordinary plants is crucial for effective remediation. Additionally, the use of compost as a source of organic material can enhance mercury mobility. The addition of organic materials such as compost can increase C organic content, cation exchange capacity (CEC), pH, and Hg-chelate formation, thereby maximizing mercury absorption by plants. This combination has a positive impact on reducing mercury levels in the soil and is environmentally safe.

Abstract

Tropical forests, vital for absorbing CO2 and maintaining ecosystem balance, are threatened by deforestation and unsustainable agricultural practices. Mixed garden or clove agroforestry systems, which combine clove cultivation with other crops, offer a sustainable alternative to traditional monoculture practices. This study aims to assess the biomass potential, carbon storage, and biodiversity in clove monoculture and mixed garden systems. The research was conducted in February 2024 at smallholder clove plantations and secondary forests in Pesaren, Sukorejo, Kendal, Central Java. The study involved primary data collection on clove monoculture and mixed garden systems using standardized plot sampling techniques. Biomass, carbon storage and carbon sequestration was calculated through field measurements utilizing allometric equations, while biodiversity was assessed using the Shannon-Wiener index based on species richness and evenness within the sampled plots. The mixed garden system closely approximates secondary forests in terms of biomass, carbon storage, CO2 sequestration, biodiversity, and species evenness, with respective values of 100.36 tons/ha, 47.17 tons/ha, 173.11 tons/ha, 2.837, and 0.91. In contrast, the clove monoculture system recorded the lowest values across all parameters: 67.03 tons/ha for biomass, 31.50 tons/ha for carbon storage, and 115.61 tons/ha for CO2 sequestration, with a dominance of one species and a Shannon-Wiener index and evenness value of 0. These results highlight the superior ecological benefits of mixed garden systems over monoculture clove plantations.
