We assessed production and decomposition associated macrozoobenthic biodiversity with plantation age ≥14 years intact reference. The monthly three...

Mangrove forests play an important role in coastal areas from ecological perspective, being able to store large amounts of carbon through sequestration and inhibiting climate change processes by absorbing CO2 the atmosphere. In recent years, there have been changes land cover converted degraded mangrove which resulted release imbalance soil structure, turn cause a flux into This research was conducted at Karang Gading Langkat Timur Laut Wildlife Reserve (KGLTLWR) North Sumatra, Indonesia....

Abstract Durio zibethinus Murr. (Malvaceae) is well known to produce secondary metabolites and has been described contain several biological activities. The present study reports the bioinformatics approach determine ten probably polyprenol reductase from durian (Durio Murr.). length of gene was varied 1313 1702 bp with protein 317 412 amino acid. Several physicochemical parameters in D. were among genes observed. Based on stability coefficients, unstable proteins except for X5 variant....

Abstract Sikundur forest area is located at Gunung Leuser National Park (GLNP), in Aras Napal, Langkat, North Sumatra Province, representing mixture of lowland Dipterocarpaceae. Two 0.5 ha permanent plots 50 x 100 m were established twenty-two years old logged-over Forest and subjectively according to topography river bank.

Biodiversitas 22: 5600-5608. The forest offers a habitat for variety of marine species, including macrozoobenthos. Macrozoobenthos live at bottom waters on hard to muddy substrates, where they break down debris, ensuring microorganisms' ease decomposing organic matter into inorganic materials that provide...

Silvofishery is the planting of mangroves in pond area. The commodities selected for silvofishery ponds include tiger shrimp, milkfish, and mangrove crab. purpose this research was to find best system based on average net present value (NPV) using a dynamic model simulation provide information about effect price changes or production silvofishery. results showed that shrimp mud crab are most feasible combinations silvofishery, having an NPV $755.71/ha/year. Meanwhile, has $332.28/ha/year,...
