Abstract

Setapuk Besar Sub-district has a mangrove area due to community conservation independently. However, few people use mangrove plant leaves as natural dyes and essential ingredients for eco-print products. This service activity is intended so the community can independently produce high-quality, attractive eco-print products. The methods applied are a presentation of material, discussion, demonstration, and practice of making eco-print products using the pounding technique. This PKM activity has increased their knowledge and skills regarding using mangrove plant leaves as natural dyes to manufacture eco-print products. The participants' enthusiasm, consisting of Surya Perdana Mandiri NGO members and Setapuk Besar Sub-District PKK women, understood the training material and practiced it at each activity stage. Based on the results of the questionnaire as an evaluation material for PKM activities, it is known that there has been a very significant change in knowledge and skills (above 80%) of the training participants for making eco-print products to increase the economic value of mangrove plants.

Abstract

Global climate change caused by greenhouse gas (GHG) emissions is currently a focus for various countries worldwide, including Indonesia. Carbon dioxide (CO2) is the main source of emissions, with a significant portion originating in urban areas. This is due to the high levels of air pollution from motor vehicles and rapid industrial growth. Urban green spaces are areas within cities that consist of non-built-up spaces filled with naturally grown or cultivated vegetation. These green spaces exist directly alongside the transportation infrastructure, which helps reduce air pollution, especially CO2, through the vegetation that makes up these areas. One type of urban green space is a green corridor, which forms elongated paths or areas. This study assessed the carbon sequestration of 17 primary road networks in Pontianak City using three allometric models. Plot positions for data collection were determined using purposive sampling, with each side accounting for 5% of the total zigzag plots. This research focused on vegetation at different growth stages, such as saplings, poles, and trees. The results were estimated at 256.86 tons ha-1 (Hardiansyah and Ridwan formula), 269.96 tons ha-1 (Chave formula), and 193 tons ha-1 (Brown formula).

Abstract

Mangrove habitats play an essential role in the sequestration and storage of carbon. Mangroves absorb CO2 through photosynthesis to create carbohydrates stored as biomass in the leaves, stems, and roots. The objective of this study was to estimate the amount of mangrove carbon in the region of the 2012 planting year located in the mangrove forest area of Setapuk Besar Village. Biomass estimation employs a survey and non-destructing method by measuring tree stem diameter at breast height (DBH). According to the findings of this study, the mangrove forest area in Setapuk Besar Village can store up to 139.62 tons of carbon per hectare, equivalent to carbon dioxide (CO2) that can be absorbed at 511.98 tons/ha. Carbon stored above and below the soil surface and soil carbon contain respective values of 65.60 tons C/ha, 50.91 tons C/ha, and 23.11 tons C/ha.Keywords: Carbon stocks, forest biomass, mangrove forest, Setapuk Besar SingkawangAbstrakEkosistem mangrove mempunyai peran untuk menyerap dan menyimpan karbon. Mangrove melakukan penyerapan CO2 melalui proses fotosintesis untuk menghasilkan karbohidrat yang tersimpan dalam bentuk biomassa pada daun, batang maupun akar. Penelitian ini dilakukan bertujuan untuk mengestimasi jumlah karbon mangrove pada areal penanaman tahun 2012 yang terdapat pada kawasan hutan mangrove Kelurahan Setapuk Besar. Estimasi biomassa menggunakan metode survei dengan pengambilan data tanpa pemanenan yaitu mengukur diameter batang setinggi dada (DBH) atau pada batas tinggi 1,3 m dari permukaan tanah. Hasil yang diperoleh pada penelitian ini menunjukkan kawasan hutan mangrove Setapuk Besar dapat menyimpan karbon sebanyak 139,62 tonC/ha dengan jumlah karbondioksida yang mampu diserap sebesar 511,98 ton/ha. Jumlah karbon yang diserap merupakan karbon tersimpan di atas permukaan tanah, di bawah permukaan tanah maupun karbon tanah dengan nilai masing-masing yaitu 65,60 tonC/ha, 50,91 tonC/ha dan 23,11 tonC/ha.Kata kunci: biomassa hutan, hutan mangrove, karbon, Setapuk Besar Singkawang

Abstract

Litsea garciae Vidal, commonly known as engkala, is an endemic medicinal plant of Borneo with promising pharmacological potential. Vegetative propagation through shoot cuttings is a practical alternative to overcome the challenges of seed-based propagation. This study investigated the effects of cutting material source (seedlings and saplings) and soaking duration in 50% Rootone-F (0, 15, 30, 45, and 60 minutes) on the rooting and shoot growth of L. garciae shoot cuttings. A factorial experiment with a completely randomized design was applied, involving ten treatment combinations with five replications each. Results showed that cuttings derived from seedlings achieved 100% survival and rooting rates regardless of Rootone-F treatment. In contrast, sapling cuttings achieved optimal rooting only after 15 minutes of soaking. The interaction of cutting source and soaking duration significantly influenced root development, while shoot growth varied only with individual treatments. Notably, seedling cuttings produced roots that were 1.3 times longer than those from sapling cuttings; however, the dry weight of sapling roots was 1.5 times greater. The dry weight of roots soaked in Rootone-F for 15 minutes significantly increased by 1.3 to 2.8 times compared to the dry weight of roots soaked for other durations. The seedling cuttings produced 1.2 times more shoots than saplings. Interestingly, cuttings without soaking treatment in Rootone-F produced the same number of new leaves as those soaked for 60 minutes but significantly more than those soaked for other durations. These results are vital for optimizing the vegetative propagation technique of L. garciae by selecting the appropriate cutting source and timing for Rootone-F immersion. Keywords: engkala, Litsea garciae, Rootone-F, shoot cuttings, vegetative propagation
