Abstract

Climate change is a global issue that requires mitigation strategies in various sectors, including forestry. Agroforestry, which combines trees with agricultural crops, is considered a strategy that can reduce greenhouse gas emissions by increasing carbon storage. This study aims to estimate and analyze the amount of carbon stored in three different land cover types found in a landscape of forest management unit (FMU), namely agroforestry coffee, monoculture coffee, and forest. Carbon stock analysis was conducted using a non-destructive approach on 36 sample plots evenly distributed across the three land cover types. The results showed that the highest carbon stock was found in forested area, followed by agroforestry coffee and monoculture coffee. However, the agroforestry system showed a fairly high carbon storage potential and was close to forest land, especially due to the presence of species such as Swietenia macrophylla and Coffea canephora. These findings indicate that the agroforestry system has great potential in climate change mitigation strategies by increasing carbon stocks, making it worthy of being an alternative to support forest conservation and rehabilitation.

Abstract

The rapid growth of Bandar Lampung City is characterized by an increasing conversion of non-built-up land into built-up areas. This condition is influenced by population growth, economic development, and the strategic position of Bandar Lampung as the capital of Lampung Province and the gateway to Sumatra Island. Such development has the potential to create pressure on land use if it is not aligned with the Spatial Plan (RTRW). This study aims to analyze the spatial pattern and distribution of urban growth, and to assess the conformity of urban growth modeling results with the Bandar Lampung Spatial Plan. This research employs a spatial-based quantitative approach. The analytical methods used include the  Cellular Automata (CA) modeling to predict urban growth up to 2041 and overlay analysis to evaluate the conformity of the modeling results with the Bandar Lampung Spatial Plan 2021–2041. The results indicate that the built-up area increased from 12,096.93 hectares in 2017 to 12,979.87 hectares in 2023, and is projected to reach 14,758.74 hectares by 2041. Spatially, urban growth tends to concentrate in peripheral areas that still have land availability and good accessibility. The conformity level of built-up land with the spatial plan decreased from 95.17% in 2023 to 89.24% in 2041. These findings indicate the need for stricter and more consistent land use control.

Abstract

ABSTRACT The largest conservation area on the island of Sumatra is Kerinci Seblat National Park (TNKS), which stretches across four provinces: West Sumatra, South Sumatra, Bengkulu, and Jambi. This area experiences various pressures that trigger land cover changes caused by natural and human factors. This study aims to determine land cover changes that occurred between 2013, 2018, and 2023 and to determine the anthropogenic activities that influence these changes. Land cover analysis was conducted using the supervised classification method with the random forest algorithm on the Google Earth Engine platform. Image classification resulted in five classes: water bodies, forests, horticultural land, open land, and shrubs. To identify the factors influencing land cover changes, an ethnoecological approach was used. The classification results were tested using the overall accuracy method, with accuracy values ​​of 88.44% in 2013, 89.94% in 2018, and 85.17% in 2023. The results showed that in the 2013–2018 period there was a decrease in forest cover, water bodies, and shrubs, while horticultural land and open land experienced an increase. In the 2018–2023 period, forest cover and open land decreased, while water bodies, horticulture, and shrubs increased. The dynamics of land cover are influenced by various anthropogenic activities such as forest encroachment, land conversion, illegal mining, historical land ownership, and economic pressures on the community after the Covid-19 pandemic. In addition, natural factors such as floods also influence changes in land cover in the TNKS area. Therefore, increased monitoring and security of the area and strengthening of conservation-based community empowerment are needed.   Keywords: ethnoecology, google earth engine, kerinci seblat national park, land cover dynamics, random forest   ABSTRAK Kawasan konservasi terluas di Pulau Sumatera adalah Taman Nasional Kerinci Seblat (TNKS) yang terbentang di empat provinsi yaitu Sumatera Barat, Sumatera Selatan, Bengkulu dan Jambi. Kawasan ini mengalami berbagai tekanan yang memicu perubahan tutupan lahan yang disebabkan oleh faktor alam dan manusia. Penelitian ini bertujuan untuk mengetahui perubahan penutupan lahan yang terjadi pada kurun waktu tahun 2013, 2018 dan 2023 serta mengetahui aktivitas antropogenik yang mempengaruhi perubahan tersebut. Analisis tutupan lahan dilakukan menggunakan metode supervised classification dengan algoritma random forest pada platform Google Earth Engine. Klasifikasi citra menghasilkan 5 kelas yaitu badan air, hutan, lahan hortikultura, lahan terbuka dan semak belukar. Untuk mengetahui faktor-faktor yang mempengaruhi perubahan tutupan lahan menggunakan pendekatan etnoekologi. Hasil klasifikasi diuji menggunakan metode overall accuracy, dengan nilai akurasi sebesar 88,44% pada tahun 2013, 89,94% pada tahun 2018, dan 85,17% pada tahun 2023. Hasil penelitian menunjukkan bahwa pada periode 2013–2018 terjadi penurunan tutupan hutan, badan air, dan semak belukar, sementara lahan hortikultura dan lahan terbuka mengalami peningkatan. Pada periode 2018–2023, tutupan hutan dan lahan terbuka menurun, sedangkan badan air, hortikultura, dan semak belukar meningkat. Dinamika tutupan lahan tersebut dipengaruhi oleh berbagai aktivitas antropogenik seperti perambahan hutan, alih fungsi lahan, pertambangan ilegal, historis kepemilikan lahan, serta tekanan ekonomi masyarakat pasca pandemi Covid-19. Selain itu, faktor alam seperti banjir turut memengaruhi perubahan tutupan lahan di kawasan TNKS. Oleh karena itu, diperlukan peningkatan pengawasan dan pengamanan kawasan serta penguatan pemberdayaan masyarakat berbasis konservasi.   Kata kunci: dinamika tutupan lahan, etnoekologi, google earth engine, random forest, taman nasional kerinci seblat

Abstract

Perubahan kualitas perairan Sungai Kresek dipengaruhi oleh masukan berupa limbah industri, kegiatan domestik ataupun kegiatan pertanian. Limbah yang dihasilkan teridentifikasi sebagai limbah logam berat Cu dan Cr total. Sudut pandang toksikologi menyebutkan bahwa Cu dan Cr total dapat mempengaruhi fungsi organ pada organisme ikan.  Paparan logam berat Cu dan Cr terhadap insang secara terus menerus menyebabkan terjadinya pendarahan dan pemecahan pada sel insang. Kerusakan jaringan insang ikan dapat dianalisis sebagai proses biomonitoring kesehatan lingkungan perairan. Agen biomonitoring yang dilakukan dalam proses analisis adalah G. affinis. Penelitian ini bertujuan untuk menganalisis kerusakan jaringan insang G. affinis sebagai akibat adanya pencemaran logam berat Cu dan Cr total di Sungai kresek. Metode penelitian yang digunakan adalah metode deskriptif dengan pendekatan survei. Hasil analisis menunjukkan bahwa konsentrasi logam berat Cu pada sampel air didapatkan kisaran 0,13-0,24 ppm. Sedangkan nilai konsentrasi logam berat Cr total pada sampel air didapatkan kisaran 0,16-0,32 ppm. Berdasarkan konsentrasi tersebut, analisis jaringan insang G. affinis ditemukan jenis kerusakan berupa edema, hiperplasia dan fusi lamela. Hasil analisis parameter kualitas air, ditemukan nilai parameter suhu dan BOD berada di atas nilai baku mutu yang sudah ditentukan. Kesimpulan dari hasil penelitian menunjukkan bahwa Sungai kresek mengalami pencemaran logam berat Cu dan Cr total sehingga menyebabkan kerusakan jaringan insang G. affinis.   Inputs influence changes in the quality of the waters of the Kresek River in the form of industrial waste, domestic activities, or agricultural activities. The resulting waste was identified as Cu and Cr total heavy metal waste. The toxicological point of view states that Cu and total Cr can affect organ function in fish organisms. Continuous exposure to the heavy metals Cu and Cr in the gills causes bleeding and breakdown of the gill cells. Damage to fish gill tissue can be analyzed as a process of biomonitoring the health of the aquatic environment. The biomonitoring agent used in the analysis process is G. affinis. This study aims to investigate the damage to the gill tissue of G. affinis due to Cu and total Cr heavy metal contamination in the Kresek River. The research method used is a descriptive method with a survey approach. The analysis results showed that the heavy metal Cu concentration in the water samples was in the range of 0.13-0.24 ppm. Meanwhile, the total Cr heavy metal concentration value in water samples was found in the 0.16-0.32 ppm range. Based on these concentrations, analysis of the gill tissue of G. affinis found types of damage in the form of edema, hyperplasia, and lamella fusion. The results of the study of water quality parameters, it was found that the parameter values for temperature and BOD were above the predetermined quality standard values. The research results concluded that the Kresek River was polluted by heavy metals Cu and total Cr, which caused damage to the gill tissue of G. affinis.
