Litter is a fragment of aboveground carbon stocks, a vital bridge to the belowground carbon cycle. Land conversion to agricultural purposes will affect litter production. This study aimed to compare the litter production of natural forests with cocoa-based agroforestry systems (AFS) in West Sumatra. Litter production was measured in five different types of ecosystems, namely natural forest (NF), cocoa-rubber-based AFS (CR), multistrata cocoa-based AFS (CM), cocoa-coconut-based AFS (CC), and cocoa monoculture (M). This study is quantitative research with the collection method. The difference in litter production between the five ecosystems observed was tested using ANOVA parametric statistical method. Litter was collected monthly for one year in which litter traps were evenly distributed in each research plot. Ecosystems of NF and M produced the highest annual litter (6.04 Mg ha-1 and 4.65 Mg ha-1 respectively), while CR produced the lowest one (2.52 Mg ha-1). Although this study did not perform comprehensive modeling of decomposition dynamics, the measurement of annual litter production can provide a further understanding of the dynamics of ecosystem carbon, especially in cocoa-based agroforestry.

In recent years, fossil fuel usage and industrial activities have significantly increased, leading to higher greenhouse gas emissions and impacting global temperature, contributing to global warming and climate change. The carbon footprint measures these emissions through carbon flux rates, influenced by climate conditions, soil and water uptake, organic matter, and microbial activities. The experiment used a gas analyzer and gas chromatograph to measure samples under three conditions. The highest average flux rate was in fully enclosed vegetation (4.04 g CO2/m²/day), followed by not enclosed vegetation (4.01 g CO2/m²/day), and the lowest was 3.91 g CO2/m²/day. Results indicate that vegetation and urban parks reduce CO2 emission fluxes, with each area's vegetation state affecting soil and air temperature, pH content, and soil moisture. However, many aspects such as soil type and climate cognition can influence fluctuation of carbon fluxes in each condition.

Pengelolaan mangrove berkelanjutan memiliki pendekatan multidimensional yakni ekologi, ekonomi, sosial dan kelembagaan. Keberlanjutan pengelolaan dapat tercapai jika keempat dimensi tersebut seimbang. Namun, tidak semua daerah dapat mengimplementasikan dimensi keberlanjutan secara seimbang, salah satunya di Desa Kaliwlingi. Tujuan penelitian secara umum untuk menentukan dimensi paling berpengaruh dalam pengelolaan mangrove secara berkelanjutan, sedangkan tujuan khusus untuk menganalisis status keberlanjutan pengelolaan ekosistem mangrove di Desa Kaliwlingi ditinjau dari dimensi ekologi, dimensi sosial, dimensi ekonomi dan dimensi kelembangaan dan merekomendasikan konsep keberlanjutan pengelolaan ekosistem mangrove. Metode yang digunakan dalam penelitian ini adalah multidimensional scaling menggunakan Rapfish (Rapid Appraisal for Fisheries) untuk menentukan status keberlanjutan pengelolaan dilanjutkan dengan metode AHP (Analitical Hierarchy Process) untuk menentukan prioritas alternatif kebijakan. Hasil penelitian status keberlanjutan pengelolaan ekosistem mangrove cukup berkelanjutan dengan nilai total 63,69. Sedangkan nilai masing-masing dimensi cukup berkelanjutan dengan rincian dimensi sosial (73,65), kelembangaan (63,43), ekologi (66,78) dan ekonomi (54,34). Konsep keberlanjutan dengan prioritas melakukan pengawasan dan patroli pengamanan secara berkala, melaksanakan rehabilitasi mangrove dengan penganekaragaman bibit sesuai kondisi geofisik lingkungan, melaksanakan sosialisasi, penyadartahuan dan kapasitas masyarakat sekitar terkait mangrove, dan meningkatkan pendapatan masyarakat sekitar dengan melakukan diversifikasi produk pemanfaatan mangrove.

Seagrass ecosystems are vital for maintaining marine ecological balance, supporting the blue carbon cycle, offering habitat for marine organisms, and safeguarding coastal areas against erosion. Nevertheless, seagrass ecosystems worldwide are declining substantially due to human activities and climate change. This trend is also evident in Indonesia, where approximately 7% of seagrass coverage is lost annually. This research examines existing literature on seagrass restoration by focusing on three key approaches: spatial assessment of suitable habitats, advancements in physical restoration techniques, and the creation of predictive models for evaluating restoration outcomes. The goal is to offer comprehensive insights into the challenges and prospects for improving management and establishing more effective and sustainable restoration strategies in coastal environments. A Systematic Literature Review (SLR) combined with bibliometric analysis was conducted on 177 publications from the Scopus database spanning 2019 to 2024 to identify research trends, technological advancements, and existing challenges in seagrass restoration. The research emphasizes the necessity of a holistic approach to seagrass restoration, incorporating spatial analysis, developing flexible restoration techniques, and implementing predictive modeling and statistical assessments to enhance long-term planning and monitoring efforts. The case study in Jepara demonstrates the effectiveness of participatory approaches at the local scale, despite limitations in technology and long-term monitoring. Integrating spatial and digital technologies, strengthening local capacity, international collaboration, and multidisciplinary integration are key to improving the effectiveness and sustainability of seagrass restoration, while strengthening its contribution to coastal resilience and climate change mitigation.

AbstractThe exploitation of turtles has resulted in a decline in the turtle population. The relocation of turtle eggs from nesting habitats is a widely accepted conservation practice. This research aims to analyze the effectiveness of turtle conservation activities on Kelapa Dua Island. The study adopts a mixed-methods approach, collecting primary data through field observations and interviews and secondary data from the Kepulauan Seribu National Park Office (BTNKpS). The collected data includes information on turtle nest monitoring activities, turtle preservation techniques, and the hatching success rate. The research results show that the hawksbill turtle (Eretmochelys imbricata) is the most commonly found turtle species. The average hatching success rate over the past six years is 71.98%. This value can still be optimized to reach 80% by establishing hatcheries on the nesting islands or islands near the nesting sites. Through this strategy, monitoring can be conducted more regularly, the turtle egg relocation process can be carried out relatively quickly, and vibrations or shocks to the turtle eggs during transportation can be minimized, thus increasing the hatching success rate. Regular monitoring of the environmental conditions of the artificial nests, including temperature, pH, and humidity, is also essential to improve the hatching percentage.AbstrakEksploitasi penyu telah menyebabkan penurunan populasi penyu. Relokasi telur penyu dari habitat penetasan adalah praktik konservasi yang umum diterima. Penelitian ini bertujuan untuk menganalisis efektivitas kegiatan konservasi penyu di Pulau Kelapa Dua. Studi ini mengadopsi pendekatan metode campuran, mengumpulkan data primer melalui observasi lapangan dan wawancara serta data sekunder dari Balai Taman Nasional Kepulauan Seribu (BTNKpS). Data yang terkumpul meliputi informasi tentang kegiatan pemantauan sarang penyu, teknik pelestarian penyu, dan tingkat keberhasilan penetasan. Hasil penelitian menunjukkan bahwa penyu sisik (Eretmochelys imbricata) merupakan spesies penyu yang paling banyak ditemukan. Tingkat keberhasilan penetasan rata-rata selama enam tahun terakhir adalah 71,98%. Nilai ini masih bisa dioptimalkan hingga mencapai 80% dengan mendirikan hatchery di pulau-pulau peneluran atau pulau-pulau yang berdekatan dengan lokasi peneluran. Melalui strategi ini, pemantauan dapat dilakukan lebih rutin, proses relokasi telur penyu dapat dilakukan dengan relatif cepat, dan getaran atau benturan pada telur penyu selama proses transportasi dapat diminimalkan, sehingga meningkatkan tingkat keberhasilan penetasan. Pemantauan teratur terhadap kondisi lingkungan sarang buatan, termasuk suhu, pH, dan kelembaban, juga penting untuk meningkatkan persentase penetasan.
