The high intensity of rain increases the runoff of the mine area so that the water flowing through the drainage channel carries erosion so that the sediment pond very quickly silts up. The impact is that the water flowing from the sediment pond to the river will be cloudy, disturbing biodiversity in the river. This study aimed to evaluate the effectiveness of using geomembranes in preventing siltation in sediment ponds. This research was conducted in the monkey area of PT Antareja Mahada Makmur Site Multi Harapan Utama. This study used qualitative research methods. Data were collected through field surveys by directly observing the waters where geomembranes have been installed. The collected data were analyzed through three stages: data reduction, presentation, and conclusion drawing. The results showed that using geomembrane in drainage can reduce erosion and siltation in wastewater settling ponds. The innovative use of geomembranes in settling ponds positively impacts the environment, cost efficiency, and team understanding within the company.

Soil erosion is a serious issue in many regions, with detrimental environmental and land sustainability impacts. One approach to overcome erosion is using recycled materials such as used tires to make erosion-retaining structures. This research aims to utilize used tires as a drop structure as a barrier to erosion. This research was conducted in the monkey area of PT Antareja Mahada Makmur Site Multi Harapan Utama. This research used a qualitative approach to gain an in-depth understanding of using used tires as a drop structure. Data was collected through literature study and direct observation. The collected data will be analyzed qualitatively by organizing, compiling, and interpreting the data. The results showed that the tire drop structure used as erosion management could have various impacts on various aspects, including the impact of environmental innovation, namely increasing the use value of waste and cost efficiency because it only requires the cost of mobilization of removal and the impact on other innovations such as reducing maintenance costs.

People-plant interaction studies the complex interactions that exist between humans and the natural environment, particularly plants; it is a thorough research that covers a wide range of views, including ecological, cultural, and psychological aspects. People-plant interaction, at its foundation, investigates how humans use plants as resources and imbue them with cultural and spiritual values, plants have provided humans with food, medicine, and shelter for millennia, and they have considerable cultural and symbolic importance in various nations and cultures. Furthermore, research on people-plant interactions emphasizes the numerous ways in which exposure to plants might promote human health. Exposure to nature, particularly plants, has been demonstrated in studies to help decrease stress and boost productivity. Indoor plants have been shown to enhance air quality and provide a more pleasant environment for humans to work and live in. With our planet's serious environmental issues, understanding the intricate interactions between humans and plants is more crucial than ever. Human-caused environmental changes, such as deforestation, pollution, and climate change, have a significant influence on the natural world, including plants.

Water plays an important role in life and is a vital component that supports biodiversity and secures the existence of ecosystems. Water sampling in this study consisted of 13 stations, namely 10 stations in river waters and 3 stations in estuary areas in the waters of Lurang Village, North Wetar District, Southwest Maluku Regency, Indonesia. The water quality parameter measurement results show that the water quality conditions in several locations are below the optimum limit. Heavy metal test samples were taken from 4 locations, namely RW35, RW36, RW39 and RWBG.Ds to be tested for the metal content of Selenium (Se), Cadmium (Cd), Copper (Cu), Lead (Pb) and Mercury (Hg). The presence of heavy metals in waters is a result of pollution from industrial, agricultural and other waste products. This study aims to determine the water quality and distribution of heavy metals in the river and estuary waters in Lurang Village, North Wetar District, West Maluku Regency.

Rural tourism is one of the more important ways to realize rural revitalization. The development of rural tourism requires that the local villages have unique resources different from the cities. Rural tourism based on different resource endowments has different tourism patterns, and the final benefits are different. Taking Jiulong Community and Moyuan Village as examples, this paper discusses the development of the rural tourism models based on the natural landscape and local culture, respectively and compares the benefits of the two rural tourism models. The research shows that the rural transportation conditions for the development of rural tourism should be convenient. Both rural tourism models can further integrate the primary, secondary and tertiary industries. The green+healthy rural tourism model is conducive to the protection of the natural environment, and the green + cultural rural tourism model is conducive to the inheritance of traditional culture.

The Qinghai-Tibet Plateau, also known as the "third pole of the world", consists of widespread alpine grasslands, and the local community has taken advantage of this natural condition to develop alpine grassland livestock farming. In recent years, climate change and irrational human activities have led to serious degradation of the alpine grasslands on the Qinghai-Tibet Plateau, which has constrained the development of traditional grassland husbandry. In order to promote the ecological protection of the plateau and improve the livelihood of the people in this region, the traditional grassland livestock industry needs to be transformed and upgraded. The Qinghai-Tibet Plateau should study and reasonably learn from efficient modern pastoralism and development measures such as grass farming and migrant urbanization in the USA, Australia, and Northern Europe. Due to the special peculiarities of the natural environment and the limitations of the local socio-economic conditions, this essay combines the local natural and humanistic environment of the Qinghai-Tibet Plateau region and proposes modern measures such as grass-based storage, grazing in specific areas, and ecological migration to realize the sustainable development of alpine grassland animal husbandry, which is conducive to promote regional high quality development.

The place processing end (TPA) Ussu is located in Ussu village, Malili, East Luwu district, South Sulawesi Province. It has been operated since 2015 with a 4 ha land area and serves 5 districts, namely Malili, Angkona, Wasuponda, Towuti, and Noah. In 2019, this landfill was diverted into a system control landfill, but the implementation is still a conventional use system of open dumping. The system has a high risk for the environment, such as water pollution, soil consequence leachate, air pollution that is caused by methane gas, the emergence of disease, and the risk of landfill fire. Risk analysis is required to describe the risk toward the environment from certain activities. The study is conducted to evaluate the risk to the environment from the operational place processing end (TPA) in Ussu. The research method used is the integrated risk-based approach (IRBA) method. The experimental parameters are in the form of 20 TPA criteria parameters, four characteristics of landfill waste, and leachate parameters. Research results show that TPA Ussu scored 477.54 in the category evaluation danger ' medium ' level. The indicator has shown there are risks toward the environment at a medium level. This caused the landfill's age to be still young and hence required rehabilitation based on conditions in the field with repair system operational landfill control by gradually reducing or lowering danger risk environment.

This research is to determine the percentage of chromium and the type of solvent in terms of the physicochemical quality of wet blue and leather from the waterless tanning process. This research was carried out from November 2021 to February 2022 at the Laboratory of the Yogyakarta Center for Leather, Rubber, and Plastics. The research method used was a Nested Completely Randomized Design (CRD) with 2-factor nested patterns, Factor 1 is percentage of chromium (A = 3%, B = 4% and C = 5%) and factor 2 namely different types of solvents (L1 = Water, L2 = Ethanol and L3 = acetone) with 3 replications. The materials used in this study were Etawa crossbreed goat skin and chromium, and the type of solvents was water, ethanol, and acetone. The variables observed were the physicochemical quality of the finished leather (stricter strength, tensile strength, elongation at break, moisture content, total chromium, ash content, fat content, and pH). The data obtained from the results of the research were analyzed using Analysis of Variance (ANOVA) if there were significantly different results obtained, followed by Duncan's Multiple Range Test (DMRT). On the physicochemical quality of the finished leather (leather), the results of this study showed that the type of solvent had a very significant difference (P < 0.01) in the physicochemical quality of the leather except for pH. The percentage of chromium nested in the type of solvent showed a very significant difference (P<0.01) in the quality of the finished leather. Based on the results of the research, the percentage of chromium nested in the type of solvent was about SNI 2981:2009; from this study, it can be concluded that Phase I research had the physicochemical quality of finished leather with an average stricter strength of 14.40 N/ cm2, tensile strength 15.40 N/cm2, elongation at break 54.32%, water content 4.76%, total chromium 3.64%, ash content 4.62%, fat content 2.44% and pH 4.41.
本研究是根据无水制革过程中湿蓝和皮革的理化质量来确定铬的百分比和溶剂的类型。这项研究于2021年11月至2022年2月在日惹皮革、橡胶和塑料中心实验室进行。采用嵌套式完全随机设计(CRD)， 2因素嵌套模式，因子1为铬的百分比(a = 3%， B = 4%， C = 5%)，因子2为不同类型的溶剂(L1 =水，L2 =乙醇，L3 =丙酮)，3个重复。本研究的材料为埃塔瓦杂交山羊皮和铬，溶剂类型为水、乙醇和丙酮。观察到的变量是成品皮革的理化质量(严格强度、拉伸强度、断裂伸长率、水分含量、总铬含量、灰分含量、脂肪含量和pH值)。若研究结果存在显著差异，则采用方差分析(ANOVA)对所得数据进行分析，然后进行Duncan多元极差检验(DMRT)。在成品皮(革)的理化品质上，本研究结果表明，除ph值外，溶剂类型对成品皮的理化品质有极显著差异(P<0.01)，不同溶剂类型的铬嵌套率对成品皮的理化品质有极显著差异(P<0.01)。根据研究结果，该溶剂中嵌套铬的比例约为SNI 2981:2009;由本研究可知，一期成品皮革的理化质量为:平均硬度为14.40 N/cm2，拉伸强度为15.40 N/cm2，断裂伸长率为54.32%，含水量为4.76%，总铬含量为3.64%，灰分含量为4.62%，脂肪含量为2.44%，pH值为4.41。

The research method used was a Nested Completely Randomized Design (CRD) with 2-factor nested patterns, Factor 1 is percentage of chromium (A = 3%, B = 4% and C = 5%) and factor 2 namely different types of solvents (L1 = Water, L2 = Ethanol and L3 = acetone) with 3 replications. The materials used in this study were Etawa crossbreed goat skin and chromium, and the type of solvents was water, ethanol, and acetone. The variables observed were the physicochemical quality of the finished leather (stricter strength, tensile strength, elongation at break, moisture content, total chromium, ash content, fat content, and pH). The data obtained from the results of the research were analyzed using Analysis of Variance (ANOVA) if there were significantly different results obtained, followed by Duncan's Multiple Range Test (DMRT).
