Abstract

Oil palm plantations are one of the important carbon stocks for climate change mitigation because of their ability to store carbon and absorb free carbon from the air. This study aims to calculate carbon stocks at various stages of oil palm growth. The samples in this study were oil palm producing plants with various age classes; young plants (3-8 years), juvenile plants (9-14 years), and old plants (> 21 years) taken with a sample of 3 plots with 1 plot of 10 trees each in each age class variation using a quadrant (sample plot) plot size of 20 x 60 m with 3 replications. The sampling of understory vegetation was carried out in a measurement plot with a size of 1 m x 1 m as much as 1 sample placed in each plot of oil palm stand biomass measurement. The study was conducted using a carbon stock measurement method with a non-destructive approach using an allometric equation. In young, juvenile, and old oil palm plants. on sample plots according to the predetermined age groups. The research samples were selected by purposive sampling. In each sample, carbon stocks were measured in the oil palm plants and floor vegetation carbon stocks. The results of the study showed that carbon stock analysis showed a close relationship with plant age. Oil palm plant carbon stocks continued to increase with increasing plant age. Therefore, it can be concluded that oil palm biomass increases with increasing age in young plants (3.77 tons/ha), adolescents (12.61tons/ha), and old (>21 years, 167.82 tons/ha).

Abstract

Abstrak: Lahan dalam wilayah Kelompok Wanita Tani (KWT) Wana Puspa merupakan lahan hutan buatan, sehingga tanahnya menjadi subur. Meskipun demikian, masyarakat belum mengenal teknologi pemanfaatan lahan subur sebagai sumber pupuk hayati. KWT Wana Puspa yang beranggotakan 25 orang, memiliki permasalahan berupa belum memiliki pengetahuan yang memadai dalam mengelola dan memanfaatkan potensi lahan sebagai sumber pupuk organik dan pupuk hayati khususnya PGPR. Berdasarkan permasalahan tersebut, program PkM ini bertujuan untuk memperkenalkan teknik pembuatan PGPR dari bahan rhizosfer di lingkungan sekitar. Metode yang digunakan dalam PkM adalah penyuluhan tentang pupuk organik dan PGPR sebagai pupuk hayati serta pelatihan pembuatan PGPR. Hasil yang dicapai adalah anggota KWT Wana Puspa memiliki peningkatan pengetahuan sebesar 94% tentang pupuk organik dan pupuk hayati khususnya PGPR serta memiliki peningkatan skill pembuatan PGPR sebesar 94% sebagai suatu teknologi pelestarian lingkungan dan peningkatan potensi lahan.Abstract: The land in the Wana Puspa Women Farmers Group (WFG) area is artificial forest land, which is fertile. However, people are not familiar with the technology of using fertile land as a source of biological fertilizer. The Wana Puspa WFG consisting of 25 people, has problems in the form of inadequate knowledge in managing and utilizing the potential of land as a source of organic fertilizer and biological fertilizer, especially PGPR. Based on these problems, this Community Service Program aims to introduce techniques for making PGPR from rhizosphere materials in the surrounding environment. The method used in community service includes counseling about organic fertilizer and PGPR as biological fertilizer and training in making PGPR. The results achieved are that WFG members have increased their knowledge by 94% about organic fertilizers and biological fertilizers, especially PGPR, and have increased their skills in making PGPR by 94% as an environmental preservation technology and improving land potential.
