Abstract

Coffee farming was highly vulnerable to the impacts of climate change. Exploring the strategies used by small farmers in Tanjung Agung Village has had a big impact on climate change. This study aimed to identify the level of knowledge, adaptation practices, and polyculture practices and types of shade trees used by coffee smallholders in facing climate change in Tanjung Agung Village, Semende Darat Ulu Regency. These strategies have made a significant difference. This study used a qualitative, survey-based approach. It also conducted data collection and analysis. This process was both simultaneous and cyclical coffee smallholders have noticed the effects of climate change in the last 1-2 years. Also, 35% of smallholders have known about climate change for the last 3-5 years. Coffee smallholders use indicators to predict climate change. These indicators include increased temperatures and shifts in the rainy and dry seasons. Water availability was also an indicator. Up to 90% of small farmers take steps to reduce climate change. These steps include using better types of coffee, planting trees for shade, and controlling how far apart the coffee plants were. Farmers also make air holes and use coffee bean skins to improve the soil. Our findings show that coffee smallholders understand climate change impacts well. They also quickly use strategies to adapt their crops to the changing climate. Smallholders use 16 types of shade crops as a strategy. The most widely used shade crops were petai, mango, avocado and durian.

Abstract

Coal mining exploitation generally uses open-pit mining techniques that have implications for environmental degradation, particularly changes in the physical, chemical, and biological properties of the soil. Revegetation of reclaimed land is a strategy for restoring ecosystem functions that have been disrupted by mining activities. This study aimed to evaluate the growth potential of Pterocarpus indicus through direct planting methods and to assess the effect of fertiliser type on plant growth acceleration on post-coal mining land. Field observations were used to measure plant growth parameters, including height, stem diameter, and number of leaves. The planting material used was stem cuttings, with variations in fertiliser treatment. Plant material type, fertiliser type, and application dose had a significant effect on plant growth variables (P<0.05). Duncan’s multiple range test indicated that the use of bokashi fertiliser at a dose of 3 kg per planting hole gave the best results, as evidenced by an average plant height of 104.38 cm, an average stem diameter of 37.692 cm, and a total of 21.99 leaves. Therefore, the direct planting method using stem cuttings as planting material with the application of bokashi fertiliser at a dose of 3 kg plays an important role in accelerating vegetation recovery in coal mine reclamation.
