Abstract
Peat restoration for the issue of preventing land and forest fires in Peat Hydrological Unit (known as Kesatuan Hidrologis Gambut/KHG) Sebangau - Katingan is necessary to support the conservation function in Sebangau National Park and the buffer function outside the area for the wider community in the context of the Peat Hydrological Area. Restoration efforts are thought to have an impact on the environment, one of the aspects affected is the hydrological aspect. One indicator to determine the impact of restoration in an area is to look at the availability and sustainability of river water as reflected in the base flow parameters. In this research, flow characteristics in restored and non-restored areas will be reviewed using the flood hydrograph method. The hydrological study shows that the results of a comparison of the simulated discharge and the instantaneous measured discharge show that the restored area has a larger base flow compared to the non-restoration area. Extensive research on remote sensing technologies has been essential in examining the hydrological consequences of peat restoration, demonstrating notable enhancements in water retention and decreased carbon emissions.

Abstract
Dayak onion is one of the endemic plants of Central Kalimantan that has health benefits. Putri malu is a wild plant that grows abundantly in various places, in the roots of putri malu is known to contain useful microbes that act as PGPR. Information on microbes that act as biological controllers (biopesticides), especially fungi from the rhizosphere of Dayak and Putri malu onion plants, is still limited, as well as its ability to control this soil-borne pathogens, especially Sclerotium rolfsii. The purpose of the study was to explore fungi from rhizosphere the Dayak scallion plant and Putri malu which effectively control the soil-borne pathogen Sclerotium rolfsii. The research is quantitative descriptive with an exploratory method of fungi from the rhizosphere Dayak and Putri malu onion plants. The fungi from the exploration were identified and tested for their inhibition and effectiveness against the pathogenic fungus S. rolfsii. There were 5 fungal treatments tested, consisting of: T0 = No bio-controlling fungi (only S. rolfsii); T1 = Trichoderma sp. (origin of the rhizosphere of the shy princess plant); T2 = Trichoderma sp. (origin of the rhizosphere of the Putri malu plant); T3 = Trichoderma sp. (origin of the rhizosphere of Dayak onion plants); T4 = Trichoderma sp. (origin of the rhizosphere of Dayak onion plants). The results of the exploration obtained 4 biological control fungi identified as Trichoderma harzianum (T1), T. viride (T2) from the rhizosphere of Putri malu and T. koningii (T3), Trichoderma Rbd2 (T4) from the rhizosphere of Dayak onion plants. The four Trichoderma isolates showed an inhibition effectiveness of >60% against S. rolfsii with the inhibition category being very good, so it has the potential to be developed as a biopesticide.

Abstract
Lowland tropical rainforests are rich in biodiversity and maintain stable ecosystems. However, disturbances such as fires, natural disasters, and unsustainable logging can disrupt this stability. In Lamandau Regency, Central Kalimantan, the potential for forestry development is substantial, necessitating proper planning and implementation. This study aims to evaluate the structure, composition, biomass potential, and carbon content of forests in Benyawai and Salajaan Hills, which are proposed as Great Forest Parks (Tahura). These forests play a crucial role in supporting biodiversity, ecosystem preservation, and carbon sequestration. Research was conducted in July 2022, utilizing representative plots of 1 hectare each. The study area has a humid tropical climate with significant rainfall and diverse soil types. The research involved measuring tree diameters, heights, and species identification. Dominant species were determined based on importance value indices, and biomass and carbon content were calculated using established equations. The results showed a high species diversity with 58 species in Benyawai Hill and 47 in Salajaan Hill. Dominant species such as Ilex cymosa and Shorea laevis were identified. The forest stands displayed an inverted “J” curve typical of healthy forests, with a higher number of smaller diameter trees. Regeneration was evident, with species like Ilex cymosa and Shorea laevis present in all strata from seedlings to mature trees. Biomass and carbon content were significant, highlighting the forests’ potential in carbon sequestration. Proper management of these forests is essential for maintaining their role in mitigating climate change through CO2 absorption. This study provides baseline data crucial for future forest conservation and carbon trading regulations.

Abstract
Environmental justice has become a central issue in the global discourse on sustainable development and social welfare. Environmental justice focuses on the fair distribution of environmental burdens and access to natural resources among all groups in society. In the midst of these dynamics, the role of political leaders becomes crucial as agents of change capable of promoting environmental justice. This research aims to analyze the role of political leaders in promoting environmental justice through a bibliometric approach. The bibliometric method is used to identify research trends, scientific collaborations, and intellectual maps of relevant scientific works. This study collected data from the Scopus academic database. The data collected included articles, conferences, and other scientific documents published in the last decade. Subsequently, this data was analyzed using CiteSpace bibliometric software to identify patterns of collaboration between authors, institutions and countries, and to map the evolution of research topics related to environmental justice and the role of political leaders. The analysis shows a significant increase in the number of publications related to environmental justice, especially in the last five years. This reflects the increasing global attention to this issue. Analysis of co-citation and co-authorship reveals that research on environmental justice is dominated by international collaborations, with authors and institutions from the United States, Europe, and Asia being the most prolific. Some of the key themes emerging in the literature include environmental policy, public participation, and the role of regulation in promoting environmental justice. Furthermore, analyses show that political leaders play diverse roles in promoting environmental justice.

Published: December 2024

Abstract
This study analyzes the Gorontalo customary law approach in the transfer of land rights through the Tayade system, which separates land rights and plant rights. In the context of Gorontalo, although there is no formal regulation that specifically regulates Tayade, this practice remains dominant. It creates legal uncertainty for land and plant owners due to the absence of definite legal rules used to separate the transfer of land rights from plants. This paper conducts a comparative analysis to evaluate the impact of the Tayade system on legal certainty, rights transfer mechanisms, land management principles, and the potential for social conflict with statutory, conceptual, and comparative approach methods. The research seeks to offer practical solutions to harmonize the Tayade system with Indonesia’s land law framework through an analysis of the alignment between customary and positive Law. This research aims to guide Indonesian policymakers and stakeholders on practical approaches based on an analysis of Tayade practices to strengthen legal certainty and reduce potential conflicts in land rights management.

Abstract
The landslide that occurred on January 24, 2019, became the largest landslide in history in the Jenelata sub-watershed. This study aims to determine mitigation priorities by analyzing the characteristics of landscape escape around landslide-prone areas in the Jenelata Sub-watershed, Jeneberang Watershed. After learning the characteristics of landscape-lifescape, a spatial-AHP analysis was carried out to assess which programs are suitable for implementation in the Jenelata Sub Watershed, Jeneberang Watershed. On the basis on the results of the spatial-AHP analysis, the agroforestry system is a mitigation direction that can be carried out near all villages in the Jenelata Sub Watershed, with an area of 9788 hectares or 42% of the total area of the Jenelata Sub Watershed. In addition, agroforestry can promote soil and water conservation, with 382 hectares (2%), and protection, with 886 hectares or 4% of the total area of the Jenelata Sub Watershed. In addition, a merger can be made between each mitigation directive of 2444 hectares, or 11% of the total area of the Jenelata Sub Watershed, which can be adjusted to land needs, and the remaining 9424 hectares (41%) are unsuitable for mitigation activities.

Published: December 2024

Abstract
Large oranges are one of the leading commodities in the Pangkep area, South Sulawesi. However, farmers face challenges regarding water availability for watering orange plants. This is because the water in the soil cannot meet the water needs of citrus plants during the dry season. On the other hand, secondary forests have the potential and function to maintain environmental balance. One of the important functions of secondary forests is to provide water through the infiltration process in the hydrological cycle. This research aims to determine the physical properties of the soil and differences in infiltration rates using the Horton method in orange groves and secondary forests in the Segeri Watershed. The necessary data includes the RBI land cover map in the Segeri watershed to determine soil sampling locations, which are then tested in the laboratory to obtain values for bulk density, soil porosity, organic matter, permeability, and soil structure. The infiltration rate is then measured until it reaches a constant value in its decline. This research found the values of bulk density, soil porosity, permeability, organic matter, and soil texture class in orange groves, respectively, as 265 gr/cm³, 56.74%, 7.62 cm/hour, 1.85%, and sandy loam. Meanwhile, in secondary forests, these values were 218 gr/cm³, 58.47%, 7.87 cm/hour, 3.71%, and sandy clay loam. The average infiltration rate in orange groves is 12.1 cm/hour, while the average infiltration rate in secondary forests is 15 cm/hour.

Published: December 2024

Abstract
Wood is a valuable lignocellulosic resource used in construction, plywood, pulp, and paper. However, forest degradation makes obtaining high-quality wood for building materials challenging. Despite the generally lower quality, community candlenut woods show potential as an alternative commercial raw material. This study aimed to improve wood quality by engineering a biosynthetic pathway for chemical components, specifically through lignin overexpression using the 4CL gene in candlenut wood. The study examined the effects of different growing environments, particularly altitudes, on lignin content and primary design suitability. Tree samples from various heights were analysed for lignin content using chemical analysis. Candlenut DNA was separated and amplified using PCR with 4CL gene primers. Results showed an average lignin content of 18.4%, with no significant difference across different altitudes, classifying the lignin content as low. Due to unsuccessful amplification, the 4CL gene could not be used as a candidate for lignin enhancement in candlenut wood.

Abstract
The forest, known as ale’ in the Bugis language, is integral to Bugis culture. In Lilirilau District, Soppeng Regency, Indonesia, the Baringeng community hosts a harvest thanksgiving ceremony involving forest-related rituals imbued with symbolic significance for maintaining human-nature harmony. This study elucidates the ceremony’s rituals and symbolism while documenting contemporary agricultural practices and responses to advancements. Methodologies include literature reviews, in-depth interviews, and participant observations. The study addresses: (1) the unique aspects of the Baringeng community’s harvest thanksgiving ceremony, focusing on the rituals of mappatettong alé, manno salo, and mattu’bang alé; (2) the symbolic meanings of these rituals, which honor the forest as nyawana linoe (the essence of nature) and water for its purifying properties; and (3) current agricultural conditions and community responses. The research concludes that the ceremony’s significance has waned due to societal changes and a focus on agricultural productivity, necessitating cultural interventions to preserve ecological wisdom for sustainable development.
Designing a Net-Zero Energy and Chemical-Free Wastewater Treatment Plant for a University Campus in Quito, Ecuador
Authors: Damián-Chalán Andreina , Daza-Donoso Pablo , Albuja-Sanchez Jorge 
Published: December 2024

Abstract
According to data from 2021, approximately 22% of the nationally distributed water in Ecuador enters wastewater treatment plants, while 52% of untreated water is directly discharged into water bodies, such as rivers. The traditional water treatment method is costly and prevents installation in rural areas and/or populations with less than 20,000 inhabitants. Therefore, the application of non-conventional and low-cost technologies for wastewater treatment would improve the statistics and quality of life of these populations. This design allows for the implementation of a net-zero energy and chemical-free Wastewater Pilot Wastewater Treatment Plant (PWTP) on a university campus in Quito, Ecuador, which will include preliminary, primary, secondary, and treatments, providing a space for researchers to develop new technologies for secondary treatment based on low-cost, natural biological processes to improve the efficiency and reduce the environmental impact of wastewater.

Published: December 2024

Abstract
Sustainable development in Ecuador faces a significant challenge due to the lack of jurisprudence that integrates sustainability principles into judicial decisions, compounded by the prevalence of environmental conflicts and the absence of specific studies. This study aimed to analyze how Ecuadorian courts applied these principles in their rulings on protective actions resolved in the Northern Judicial Complex of Quito, to identify decision-making patterns and potential cognitive biases in the adjudication process. The analysis adopts both a quantitative and qualitative approach to 1,020 cases resolved in 2023. The systematic review considers the legal and environmental context, as well as a detailed examination of judicial rulings to assess the application of sustainable development principles. Cases were classified based on the dimensions of sustainable development to which the violated rights were linked. The results indicated that a total of 156 accepted cases directly declared the violation of economic, social, cultural, and environmental rights, with 1 case indirectly involving environmental protection. This represents 15.29% of the total reviewed cases and 56.32% of the accepted cases. Of the total, 98.72% were linked to the economic and social dimension, while only 1.28% corresponded to the environmental dimension of sustainable development. Ecuadorian courts demonstrate a low level of integration of sustainability dimensions in their rulings, hindering the progress of sustainable development in the country. The ambiguity in defining these principles increases judicial discretion and the likelihood of biases in decisions. Therefore, a more systematic approach and ongoing training are needed to help judges avoid biases in their rulings.

Published: December 2024

Abstract
Cheese production, an ancient technique that has endured through the centuries, has evolved to incorporate a variety of coagulants, each with specific characteristics and applications. However, the industry now faces a sustainability-related challenge: the need to find ethical and efficient alternatives to calf rennet, as its use raises significant environmental concerns, as well as ethical and occupational health issues due to exposure to contaminants in the production environment. This study explores how different types of rennets (animal, vegetable, microbial, and recombinant) can contribute to a more sustainable, productive, and safer cheese production, adapting to the growing market demands for environmentally respectful practices. Through a methodology that included a literature review, the characteristics of these rennets and their effect on the organoleptic, microbiological, and productivity aspects of cheese production were identified and compared. The results indicated that, although calf rennet remains preferred for its coagulating properties, vegetable and microbial alternatives are gaining ground due to their adaptability, efficiency, and lower environmental impact. This diversification of rennet sources not only meets ethical, commercial, and food security demands but also affects the income of small producers by enabling more sustainable practices. However, more empirical research is needed to optimize these processes across different production contexts and enhance both productivity and sustainability.

Abstract
Melanotaenia ajamaruensis is an endemic rainbow fish in Lake Ajamaru, Papua, Indonesia. This ornamental fish has stunning coloration, but studies of its biological characteristics are still relatively limited. Endemic fish are susceptible to changes in environmental factors, such as temperature. This study examined the fish performance reared at ambient (25–26°C) and high temperature (31–32°C) for three periods between March 2021 and August 2022. The first period of research was carried out for 200 days using two-month-old juveniles, followed by a second period of 60 days, then continued with a third period to observe reproductive potential. The results revealed that the survival rate (SR) ranged from 67% to 100%. There was no significant difference in fish length growth (GR-L) or specific growth rate in length (SGR-L) between the two conditions. High temperatures lowered weight growth (GR-W) by 50–66.7% and SGR-W by 43.78-44%, decreased the quantity of vividly colored fish by 30% and rendered the fish unable to reproduce. However, this fish could breed after being kept at ambient temperature for six months despite having significantly inferior reproductive components. High temperatures have been shown to impede the weight growth and reproduction of M. ajamaruensis.
