Abstract

The gold mining in Sepauk District in the watershed and the mainland causes problems from the economic, social, and environmental standpoint. The purpose of this study is to analyze the social, economic, and environmental conditions in Sepauk District of Sintang Regency and the impact of the traditional gold mining on the social, economic, and environmental aspects. This study uses a descriptive qualitative model where researchers collect data through observations, interviews, and documentation. The social aspects of education have increased considerably; health is still very limited with the lack of health facilities and medical personnel; age and sex, no children and women employed, average working age for work; tribe and religion is not a problem to work as a miner. Economic aspect in the form of livelihood change, formerly majority farming and now become miner and income enough increase and its environmental aspect is caused by road damage, river water pollution, land damage and noise. The traditional gold mining activities have had a positive impact such as improving the welfare of the people and reducing unemployment; yet, it also brings negative impact, such as health problems, road damage, river pollution, land damage, noise pollution, and land conflicts. Thus, it is recommended that the government guide and supervise the community in conducting the mining activities.Keywords: Economy, Environment, Gold mining, Social

Abstract

The coastal area of Labuhan Sumbawa Village has strategic value for economic development and improving people's welfare, but is very vulnerable to damage due to the use of multifunctional space, so that coastal management is urgently needed that focuses on regional characteristics, by placing three pillars of sustainable development, namely ecology, economy, and social. This study aims to identify problems and models of coastal area management in Labuhan Sumbawa Village, Labuhan Badas District, Sumbawa. The research method used is descriptive research method. Data was collected by means of observation and semi-structured interviews. Accidental sampling technique and qualitative data analysis. The results showed that in the coastal area of the research location, identified: (1) Physical damage to the environment, including: a) Damage to ecosystems (ecosystems, coral reefs, seagrass beds, and beaches); b) Damage to fish resources; c) Pollution; d) Abrasion, sedimentation, and siltation; and d) Natural disasters (floods); (2) Socio-economic problems, including: a) The problem of poverty and the low level of education of the population; b) Limited funds in development; and c) Lack of understanding of the value of coastal area resources; (3) Institutional problems, including: a) The problem of conflict of authority, which can occur due to sectoral development; b) The problem of legal uncertainty. The coastal area management models that can be applied are: (1) traditional management; (2) community-based coastal area resource management; (3) Co-management, and; (4) Ecosystem Based Fisheries Management (EBFM). The conclusion of the study is that damage to coastal areas will have an impact on ecological, economic, and social conditions so that multi-stakeholder involvement is very important in sustainable coastal area management.Keywords: Ecology, economy, social, coastal, model

Abstract

The ecological feasibility of sago plants is not strong enough to determine sago as a commodity that can be developed in the upstream area. The research objective was to assess the community's perception of the strategy for water of sago land management in Salu Paku sub-watershed, the upper part of Rongkong watershed. The research begins with the socialization of the rainfed sago land water management strategy. The research consisted of two stages (before socialization and after socialization). The results showed that before the socialization, 100% of the community understood that sago land did not need water management, but after socialization, the community understood that sago could be developed in dryland conditions if there was water management. The community previously understood that it was not important to regulate the number of plants in one clump, after receiving additional information, generally, they wanted to regulate the number of sago trees by maintaining two tillers, one weaning plant, and two tillers during the weaning period. phase, and in the tree phase raise one tree plus one wean and two chicks. The public perception of water conservation measures before the socialization was doubtful 100%, after the socialization, the perception increased 95% (willing to make terraces and dead-end trenches), and 5% were still in doubt. Public perception about the addition of organic fertilizer to sago land before the socialization was doubtful 100%, after the socialization, 95% of the people agreed to add organic fertilizer, although 5% still had doubts

Abstract

One of the important commodities for the Indonesian people produced from the marine sector is salt. The variety of salting problems has more or less affected the competitiveness of people's salt in each region in Indonesia. This condition clearly affects the welfare of salt farmers, because the selling price of salt received by farmers tends to be low. Tuban Regency is a coastal area that contributes to the achievement of salt production targets in East Java. Geographically, Tuban Regency is in the middle of salt processing areas, namely Surabaya-Gresik and Pati-Rembang, where these areas are also salt producing areas as well. Seeing this phenomenon, this study was conducted to analyze what factors affect the competitiveness of local salt in Tuban Regency. This study used primary data with a total of 90 respondents conducted randomly or random sampling. The analysis tool used is factor analysis. The research location was carried out in the salt production center area in Tuban regency, namely in Palang district and Tambakboyo district. From the results of the analysis, the results were obtained that there were five (5) factors that affect the competitiveness of local salt in Tuban Regency from the most influential to the factors that had the least influence, namely (1) Government Assistance, (2) Supporters, (3) Production Time and Government Regulations, (4) Social, and (5) Production and Post-Production.

Abstract

Indonesia’s coffee cultivation covers 1.25 million hectares, predominantly managed by smallholders (98.14%). Malang Regency, a key production area in East Java, experienced a sharp yield decline from 29,728 tonnes (2021) to 14,151 tonnes (2022). This study investigates smallholder plantations in the Kletek sub-watershed, emphasising the role of shade vegetation in coffee growth. Shade density critically influences productivity and ecological resilience. To support sustainable management, vegetation cover is assessed via remote sensing using the Normalised Difference Vegetation Index (NDVI), enabling spatial analysis of canopy structure. This research aims to analyse the types of coffee shade trees on smallholder coffee farms. NDVI is used to distinguish differences in land cover, including coffee shade. The study employed a land survey using the grid method with 30 observation points. Spatial analysis involves spectral transformation of Sentinel-2A Harmonised imagery, while statistical analysis uses correlation tests. Smallholder coffee farms in the Kletek Sub-watershed feature shade plants such as lamtoro, mahogany, and banana trees. NDVI values across these plantations ranged from moderate (0.4–0.5) to very high (>0.6) vegetation density, showing a strong correlation with land cover conditions (r = 0.80). This confirms NDVI as an effective remote sensing tool for assessing shade vegetation, significantly influencing coffee productivity and ecological resilience. The findings support NDVI-based monitoring for precision agriculture and adaptive management, with scalable applications in sustainable land-use planning, agroforestry optimisation, and climate-resilient coffee cultivation in regions such as Malang Regency, where production has declined.
