“…There needs to be a periodic measurement of suspended load for sediment building planning [19]. Similar studies on the measurements of water discharge and suspended load have also examined the relationships between water discharge and water level, between suspended load and water level, and between suspended load and water discharge [31]- [35]. For review, research by [3] provides information that the bedloads at Poncowati weir in Tambong river, Gembleng weir in Bomo river, Jambewangi weir in Setail river, and Karangdoro weir in Baru river were 0.948 tons/day, 0.1778 tons/day, 0.356 tons/day, and 0.469 tons/day, respectively.…”

A sediment transportation process may lead to a river overflow. This was the case with 4 major rivers in Banyuwangi Regency, namely Baru, Setail, Bomo, and Tambong rivers. The watersheds in Banyuwangi are shaped alike to bird feathers, belonging to the dendritic drainage type with an elongated drainage form, relatively small discharge, and flooding that occurs for a relatively long time. The use of downstream areas by residents for sand mining indicates a high amount of sediment in the watersheds. The purpose of this study was to model the sediment load in the bird feather-type watersheds along the main rivers of Banyuwangi Regency. Data from water level, flow velocity, and discharge measurements were correlated with the results of suspended load and bedload analyses to create rating curves. Equations for the modeling of the sediment load in the bird feather-type watersheds were generated by regression methods. The results of the modeling of the sediment load in the bird feather-type watersheds in Banyuwangi Regency using the equations above were obtained by the suspended load model qs (tons/day) = 27.0 - 39.0.h (m) – 122.V (m/s) + 71.1.q (m3/s), with R-Sq = 59.4%, and by the bedload model qb (tons/day) = - 0.0758 + 0.0853.h (m) + 0.0585.V (m/s) + 0.165.q (m3/s), with R-Sq = 73.6%. Sediment load modeling can be used as a projection of sediment transport in studies on type C excavations along the major rivers in Banyuwangi Regency.

“…Generally, plant carbon is stored in the form of biomass, which is about 45-55%, through the process of photosynthesis. Accordingly, Plants or trees either in the primary forest or agroforestry serve as important carbon storage [4].…”

The different agroforestry management can perform different potentials for carbon sequestration. The study aimed to estimate the potential of carbon stocks in various types of agroforestry in the last 20 years in Senaru area, the sub district of Bayan, Northern Lombok. The study was conducted from June to August 2022. Different types of agroforestry managed on entisols include mahogany based agroforestry (Swietenia mahagoni), Cacao-based agroforestry (Theobroma cacao), Coffee-based agroforestry (Robusta Coffee), Sengon based- agroforestry (Albizia chinensis), and Porang-based agroforestry (Amorphophallus muelleri). Samples for measuring above ground biomass at each agroforestry were carried out on plot area of 20 m x 20 m. Samples for soil organic carbon (SOC) was carried out by collecting 4 composite soil samples at each type of agroforestry at soil depth of 0-5 cm and 5-10 cm. In addition to the soil organic-C, measurements were also made on soil bulk density, total porosity, and soil texture. The results of the study showed that the total carbon stocks varied under different types of agroforestry. Mahogany based agroforestry produced the highest total carbon stocks, 440.64 ton.ha−1, and subsequently, it was followed by sengon-based agroforestry, coffee, cocoa and porang with values of 371.54 ton ha−1, 305.33 ton ha−1, 166.15 ton ha−1 and 153.93 ton ha−1 respectively. Thus, to support sustainable agroforestry management in this area, it is important to consider the timber tree stands that potentially produce high biomass as well as the need to improve the diversity of high biomass vegetation in areas with low vegetation density.
