Modelling for Estimation Carbon Stocks in Land Cover Using A System Dynamic Approach (Case Study: Prabumulih City, South Sumatera, Indonesia)

Human activities, which have interfered with the ecological system, have led to global warming. This has led to the release of carbon stocks into the atmosphere, thereby reducing the function of carbon sinks in places with vegetated land. With increased human activities, vegetated land will soon become non-vegetated. This is because the increased human activities have led to the absorption of higher amounts of carbon in the atmosphere than the required level. Therefore, this study aimed to estimate land cover on carbon stocks in Prabumulih City, South Sumatera Province, Indonesia. The study employed a random field survey using a dynamic system, with the results showing that land cover consisted of oil palm plantations, mixed plantations, grass, swamp shrubs, and rivers. However, the area was dominated by rubber plantations, and as a result, the carbon stocks continued to decline. For instance, in 2008, the level of carbon stock was 2,438.72 Gg and fell to 2,190.85 Gg in 2020, indicating a 4.8% decrease. It is projected that by 2030, the carbon stock in land cover will be 1,988.07 Gg

Fariani A, Muslim G, Nurdin AS, Pratama ANT, Sonia A. 2020. In sacco local swamp grass hemiselulose degradation pattern on swamp buffalo (South Sumatra). In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Studies on the value of swamp forage digestion have been widely conducted, but information about the pattern and rate of degradation of swamp forage is still low. The study aims to evaluate the pattern of hemicellulose degradation of swamp grass in swamp buffalo in Sacco. The study was conducted using Complete Random Design with six treatments and three replications as follows: Rumput Bento Rayap (RBR), Rumput Kumpai Minyak (RKM), Rumput Kumpai Tembaga (RKT), Rumput Kumpai Padi (RKP), Rumput Sendayan (RSN) dan Rumput Purun Tikus (RPT). The observed parameter is the pattern of hemicellulose degradation of swamp grass. The results showed different degradation patterns in six types of swamp grass (p<0.05). Fraction A, Rumput Bento Rayap has the highest score (38.60%) compared to other treatments, and a fraction, b was founded in Rumput Kumpai Padi (19.93 %). Meanwhile, the highest fraction c value was founded in Rumput Sendayan (0.35 %hours) but is no different when compared to Rumput Purun Tikus (0.32 %hours). The highest total digestibility value at incubation period 6 – 48 hours (P-value) was founded in the treatment of Rumput Purun Tikus (333.06 %). Based on the results of this study can be concluded that Rumput Purun tikus has the best digestibility value compared to the other six types of swamp grass

Effect of Mineral Mix Supplementation in Silage of Palm Frond Grated (PFG) and Palm Sludge on Digestibility and Delay Quality By In Vitro Methods

By-products from oil palm can feed ruminants such as palm fronds (OPF) and palm oil sludge (PS). Judging from its continuous, cheap, and abundant availability from the palm oil industry, as well as a source of fiber or a component in complete feed for ruminants, it is the potential that can be used as animal feed. However, the use of oil palm fronds in livestock production is minimal due to their complex fiber structure, high lignin content, and low protein content. So, it needs management technology on OPF. The design used was a Completely Randomized Design (CRD) with three treatments and five repetitions: P0 Palm frond silage (30%) + palm sludge (70%) P1 Silage of palm fronds (30%) + palm sludge (70%) + Mineral Mix 1% P2Palm frond silage (30%) + palm sludge (70%) + Mineral Mix 2%. The data obtained were analyzed for variance according to the design used, and if there were differences between the treatments, continued analysis using the Duncan Multi Range Test Based on the results of statistical analysis showed that the silage treatment of palm frond powder and palm sludge supplemented with a mineral mix in vitro decreased the digestibility value of dry matter (P&lt;0.05). However, different results were shown in the digestibility of organic matter, where increased digestibility occurred in treatment with supplementation of mineral mixes. The statistical analysis showed that the silage treatment of palm frond powder and palm sludge supplemented with the mineral mix in vitro showed no significant difference between treatments (P&gt;0.05) on VFA and NH3 values. Based on the study's results, it can be concluded that mineral mix supplementation in the silage of palm frond powder and palm sludge significantly decreases the digestibility of dry matter but increases the digestibility value of organic matter. Nevertheless, the treatment given did not have a significant effect on the quality of the fermentation, which included VFA and NH3
