Abstract

The discharge of a river basin is influenced by several factors such as rainfall, land use or vegetation conditions, soil type, and topography. This study was conducted to determine the magnitude of the instantaneous flow rate of the Tubo River Basin in the downstream section. The instantaneous flow rate was determined using the floatation method. The floatation method is the simplest method that can be done to measure the flow rate by flowing an object that can float on the water surface. This study used a ping pong ball with a distance of 10 m. Discharge (m3/s) can be determined by the formula of the river cross-sectional area (m2) multiplied by the river water flow rate (m/s). The river cross-sectional area is determined by measuring the river width multiplied by the average water depth. Meanwhile, the flow velocity can be determined by calculating the path length divided by the average travel time of the ping pong ball. Measurements were carried out on a straight section of the river and were carried out 10 times in the morning and afternoon. The results showed that the average flow discharge of the Tubo River Basin in the downstream section was 28.18 m3/s. The use of forest land of 15.15 ha is smaller than non-forest land of 249.66 ha, which has an impact on the small discharge rate. Land cover characteristics and low rainfall factors influence the discharge rate.

Abstract

Silvicultural systems play a vital role in the implementation of social forestry programs; however, their application at the community level continues to face various challenges. This study aims to describe silvicultural practices implemented by local communities within the Community Forest (Hutan Kemasyarakatan/HKm) program and to identify the limiting factors influencing their application. The research employed a descriptive qualitative approach, with data collected through observation, interviews, questionnaires, and document analysis. The results indicate that the community of Alu Village has applied a range of silvicultural practices, despite most respondents being unfamiliar with the technical term “silviculture.” Agroforestry is the predominant system adopted, integrating forest tree species such as teak, mahogany, and gmelina with plantation crops including cocoa, coffee, and candlenut, as well as food crops (maize and chili) and fruit trees (durian, rambutan, and nutmeg). Community knowledge related to silvicultural management is largely derived from intergenerational experience, while access to formal extension services remains limited. Constraints affecting the implementation of silvicultural practices can be categorized into technical and non-technical factors. Technical constraints include difficulties in seedling preparation and transportation, limited road access, and unpredictable weather conditions. Non-technical constraints involve limited financial resources, inadequate training opportunities, and insufficient support from relevant institutions.
