Abstract

The impact of salinity on paddy production in Indonesia was pronounced with an average decline of 6.83% (2015-2019). Salinity interferes with macronutrients' absorption into plants, causing stunted growth (salinity contributed to a 42% decrease in paddy production). One solution to solve the salinity problem in paddy is to use saline varieties. There were very few studies on macronutrient content analysis in resistant varieties response to the salinity source's distance.  This research conducted in Jabon Sidoarjo, Indonesia, aims to see the macronutrient response and plant growth to the saline source's distance. This research was conducted in Jabon District, Sidoarjo Regency, using two transects with a length of 2 km and 3.4 km, respectively. The distance between the research location and the salinity source was 10.65 km.  The survey used a free grid to adjust paddy fields' location and the presence of resistant varieties. The results showed that the closer to the salinity source, the salinity indicators consisting of Electrical Conductivity, Sodium Adsorption Ratio, Exchangeable Sodium Percentage, and pH H2O would increase. The increase in salinity then affects the decrease in macronutrients (Nitrogen, Phosphor, and Kalium) in plants. However, tillers and leaves (length and number) were unaffected by high salinity levels in the soil.

Abstract

One of endemic flora that has become an icon in the Bromo Tengger Semeru National Park (TNBTS) area is the Edelweiss Flower. The existence of tourism developments in the Bromo Tengger Semeru National Park (TNBTS) area makes the demand for Edelweiss flowers as souvenirs even greater. It affects the economic value of these commodities. The population decline threatens its availability for the Tengger indigenous people who use Edelweiss Flowers as offerings that other components cannot replace. Until 2017, several Wonokitri Village communities, under the guidance of TNBTS, formed a farmer group called Hulun Hyang to conserve the Edelweiss Flower ex-situ. It was a long journey for the Hulun Hyang farmer group to get a breeding permit from the KLHK regarding wanawiyata widyakarya. This study aims to measure the willingness to pay of Edelweiss Park tourists for edelweiss flowers from the Ex-Situ conservation of the Hulun Hyang Farmer Group and determine what factors influence the willingness to pay. This study uses primary data with the number of respondents as many as 100 respondents who were conducted randomly or random sampling. The contingent valuation method (CVM) approach can estimate willingness to pay. This study's analytical tool uses multiple linear regression on SPSS 22. Based on the analysis, the average willingness to pay per person for a simple series containing 100 stalks of Edelweiss flowers is Rp. 36,307.00, with a total value of willingness to pay Rp. 3,667,000.00. The factors that are thought to significantly influence the value of willingness to pay for Edelweiss Flowers from Ex-situ Conservation of the "Hulun Hyang" Farmer Group in the Bromo Tengger Semeru National Park are the latest education and monthly income.

Abstract

The broader transformation of forested areas into open land is commonly referred to as deforestation. Deforestation poses a significant challenge to forest preservation and environmental sustainability. This study aims to employ remote sensing methods to analyze the spatial patterns of deforestation in the Soeharto Forest. It is complemented by in-depth interview data gathered from individuals engaged in forest exploitation activities. The findings reveal a notable decline in land cover within the Soeharto Forest Park area from 1992 to 2022, resulting in a reduction to 335,994,000,000 m2. Further analysis of the in-depth interview data indicates that forest fringe communities have taken control of 15,536,393.69 m2 of land to fulfill their livelihood and cultivation needs. The decline in land cover will also be more critical because of moving the national capital. The research results also discussed land cover areas using remote sensing. However, social support discusses whether land cover change is caused by land tenure by forest fringe communities and plans to relocate the national capital. Where this is also influenced by the formulation of government policies that have not balanced bee interests of ecology and the social culture ture of the community.

Abstract

This study investigates the integration of Local Ecological Knowledge (LEK) in the sustainable development of Banyuwangi Liberica coffee, focusing on coffee farmers' ancestral heritage and local knowledge systems. Practices in land management, cultivation techniques, pest control, and pruning waste utilization are examined. Through qualitative data analysis from interviews and field observations, the research highlights the depth and significance of LEK in maintaining environmental sustainability and cultural heritage. Liberica coffee farmers possess a wealth of inherited LEK, encompassing ecological dynamics, sustainable agriculture, and natural resource conservation. Farmers integrate this knowledge into decision-making, evaluating innovations through research trials. Adopting appropriate practices preserves local ecosystems and maintains Liberica coffee's authenticity. The study underscores LEK's crucial role in land management and cultivation, with seedlings and repurposing waste for soil fertility. Pruning and using shade plant branches optimize fruit production and microclimate regulation. Natural pest control minimizes chemical pesticide use, preserving the coffee ecosystem's delicate balance and supporting biodiversity. Integrating LEK not only fosters environmental sustainability but also strengthens the community's social and cultural fabric. Coffee farmers' ancestral heritage and deep connection with the land contribute to the resilience of local agricultural practices, promoting the well-being of both farmers and the ecosystem.

Abstract

Produksi kentang di Indonesia berkontribusi + 0,3% dari total produksi dunia sebesar + 388.191.000 ton. Kentang merupakan komoditas hortikultura esensial di Indonesia dengan permintaan sekitar 2,82 kg ha-1 kapita-1 pada tahun 2021. Saat ini terjadi defisit ketersediaan kentang yang mencapai 4.845.910 ton yang diperparah dengan terus menurunnya produksi kentang nasional (1.164.738 ton). Penyakit hawar daun (Phytophthora infestans) merupakan salah satu masalah utama penyebab penurunan produksi kentang (kehilangan hasil antara 10-100%). Penyebaran penyakit hawar daun sulit untuk diidentifikasi secara real time, sehingga diperlukan teknologi tepat guna yang dapat memberikan informasi secara cepat dan akurat. Penelitian ini bertujuan untuk melihat bagaimana foto udara (dari UAV) memperkirakan sebaran penyakit hawar daun pada kentang. Foto UAV diubah menjadi indeks NDVI, RDVI, SAVI, SR, ARVI-2, DVI, IPVI, dan GCI. Data pengukuran indeks penyakit hawar daun akan dikorelasikan dan dipilih yang terbaik untuk mendapatkan rumus regresi distribusi spasial penyakit hawar daun. Lokasi penelitian berada di Kecamatan Bumiaji, Kota Batu, Indonesia. Titik pengamatan di lapangan sebanyak 50 titik pengamatan untuk setiap luasan 3 Ha. Hasil penelitian menunjukkan bahwa semua indeks berkorelasi positif (> r tabel 0,34). Korelasi tertinggi pada estimasi model dari indeks NDVI (0,72). Kondisi ini sejalan dengan koefisien regresi (R2) pada NDVI yang mencapai 0,51 dengan persamaan y = 20,779 * (angka indeks NDVI) + 49,146. Analisis t-paired menunjukkan bahwa t hitung pada model (-1,10) ada pada grafik t-tabel (2,16), dan ini menegaskan bahwa rumus tersebut dapat diandalkan untuk digunakan.

Abstract

The escalating demand for Edelweiss flowers as souvenirs due to tourism development threatens their availability and economic value, impacting the indigenous Tengger community, which relies on these flowers for irreplaceable traditional offerings. The Hulun Hyang farmer group was established in 2017 under the guidance of the national park to conserve Edelweiss flowers, and subsequently obtained a cultivation permit from the Ministry of Environment and Forestry. However, the sustainable management of Edelweiss Park necessitates bolstering the group's institutional capacity as a critical agent in its development. This research examines the endogenous growth and active participation of the Hulun Hyang farmer group to strengthen their institutional capacity, enabling the establishment of deeply rooted and locally responsive mechanisms. Community development initiatives aim to foster economically and socially independent communities by enhancing agroecological management capacity by employing a strategic group development approach. Findings indicate that the institutional capacity of farmer groups is directly influenced by member dynamism and participation and indirectly impacted by leadership, member capacities, the role of extension workers, external support, and farmer characteristics. Consequently, efforts to augment the group's institutional capacity focus on promoting member dynamism and active engagement in group activities.
