Abstract

ABSTRACT This study aims to determine how much of the Precet Kawi Forest area of the Wagir Forest Pemangkuan Resort Area KPH Malang is able to store carbon reserves. The results of this study can support conservation area management activities in a sustainable and sustainable manner in relation to reducing the impact of global warming. The research was conducted at Precet Kawi Forest, Pemangkuan Hutan Wagir Resort area of KPH Malang. Data processing and determination of specific gravity were carried out at the Central Laboratory of the Islamic University of Malang. Determination of the location of the plot using purposive sampling method with an emphasis on locations with a high level of diversity. Plots were made at 3 locations and coordinates were taken using GPS. The results of this study used two allometric methods, Chave and Istomo, which showed that the potential carbon stock in the protected forest plot area had the highest carbon stock value. In the plot area of Pinus merkusii Jungh et de Vriese has the second highest carbon storage content. Judging from the Swietenia mahagoni plot has the lowest carbon storage compared to the protected forest plot and the Jungh et de Vriese Pinus merkusii plot. further research to determine the carbon content stored underground (Below ground) at the same location. Keywords: Carbon Stock, Carbon Pool, KPH Malang   ABSTRAK Penelitian ini bertujuan untuk mengetahui seberapa besar kawasan Precet Kawi Forest Wilayah Resort Pemangkuan Hutan Wagir KPH Malang mampu menyimpan candangan karbon. Hasil penelitian ini dapat menunjang kegiatan pengelolaan kawasan konservasi secara berkelanjutan dan lestari dalam kaitannya dengan pengurangan dampak pemanasan global.Penelitian dilakukan di Precet Kawi Forest, wilayah Resort Pemangkuan Hutan wagir KPH Malang. Pengolahan data dan penentuan berat jenis dilakukan di Laboratorium Pusat Universitas Islam Malang. Penentuan lokasi plot menggunakan metode purposive sampling di titik beratkan pada lokasi yang tingkat keragaman yang tinggi. Plot dibuat pada 3 lokasi dan pengambilan koordinat dengan menggunakan GPS. Pada hasil penelitian menggunakan dua metode alometrik Chave(2005) dan Istomo(2006) yang dapat diketahui potensi cadangan karbon pada area plot hutan lindung memiliki nilai cadangan karbon tertinggi. Pada area plot Pinus merkusii Jungh et de Vriese memiliki kandungan simpanan karbon tertinggi kedua. Dilihat dari plot Swietenia mahagoni memiliki simpanan karbon terendah dibandingan plot hutan lindung dan plot Pinus merkusii Jungh et de Vriese. Dalam penelitian ini dilakukan analisis kandungan karbon di atas tanah (Above ground) pada struktur jaringan hidup batang pohon, Saran dari penelitian ini yaitu perlu diadakannya penelitian lebih lanjut untuk mengetahui kandungan karbon yang tersimpan pada bawah tanah (Below ground) pada lokasi yang sama. Kata kunci: Karbon stok, carbon pool, KPH Malang.

Abstract

This study aims to determine the effect of differences in growing places altitude on the diversity of biochemical characters (glucose, vitamin C, and folic acid) of three banana cultivars (Musa acuminata (AAA)/ambon, Musa balbisiana (BBB)/kepok, and Musa paradisiaca (AAB)/raja) grown in Boyolali Regency. The study was conducted at three growing places altitudes: Kemusu (123 masl), Musuk (667 masl), and Gladagsari (806 masl). Biochemical content data were tested quantitatively using UV-Vis spectrophotometry and a refractometer, with five replications per location, then analyzed using ANOVA. The results showed significant variation between cultivars and locations in terms of vitamin C and folic acid levels, with the Musa balbisiana (BBB)/kepok cultivar in Musuk having the highest vitamin C content. Furthermore, environmental factors such as light intensity and temperature significantly influenced the variation in biochemical content. This study strengthens the understanding of the interaction between genotype and environmental factors (G × E interaction) in shaping the nutritional quality of bananas. In conclusion, the selection of appropriate cultivars and planting locations can optimize the nutritional value of bananas.
