Jeneberang watershed is one of the watersheds in the MAMMINASATA area (Maros, Makassar, Sungguminasa and Takalar). The watershed, upstream, is now in a critical condition. This study aims to identify and map land use patterns, carbon stock emissions, both in the present condition and after rehabilitation condition. The data and information used in this research are Landsat 7 ETM+ in 2006 and 2010, the Jeneberang watershed boundary map, critical land map, forest area map, rainfall data, population data, and land capability class map. The method used is the interpretation of land use or land cover, biomass calculation, and analysis with REDD ABACUS. The results showed that land use was dominated by plantations and then followed by low density forest, agricultural dry land, rice fields, water bodies, plantation forests, vacant land, shrubs, settlements, high density forests, and savannas. The direction of land cover/land use that can increase carbon sequestration is the conversion of barren land, shrubs and savannas into plantation forests and agroforestry. Potential carbon stocks for plantations, dry land agriculture and rice fields will increase to 2.295.626,32 tons in 2026.

This study aimed to investigate the physical and chemical characteristics of the soil based on the type of land management in the production forest in Banyu Urip Village, Central Lombok. Determination of the sampling point is done by employing stratified random sampling. The sampling points were 22, divided into two types of land: forest land (dominated by MPTS plants and woody plants) and agricultural land (dominated by seasonal plants). Soil samples were taken with two depths, namely 0-10 cm and 10-20 cm. Soil samples taken were disturbed and undisturbed soil with variables of physical properties (texture, bulk density, porosity, and color) and soil chemistry (C-organic). The research results on the physical properties of the soil showed that the soil texture in both types of land was dominated by dusty clay. The average porosity value in agricultural land is 49.33%, and forest land is 49.48% (unfavorable category). The average bulk density value in forest land is 1.39 g/cm3 and in agricultural land is 1.35 g/cm^3 (high category). The soil color of the two land types is dominated by dark brown. The average value of C-organic soil is 1.80% in forest land and 1.72% in agricultural land (low category).

Variability in the Patterns of Terrestrial Mammals in Visiting The Natural Salt-Licks At a Tropical Forest
Authors: Mojiol Andy R. , Lim Wing-Shen
Published: October 2022

Natural salt-licks are visited frequently by various species of terrestrial mammals, but the variability in environmental conditions can modify the mammalian visitation pattern in an inland tropical forest. Given that no similar research has been conducted at Segaliud-Lokan Forest Reserve in Sabah (Malaysia), a scientific research was conducted from July 2019 to February 2020 (eight months), to investigate the effects of variability in the environmental conditions on mammalian visitation patterns to the local natural salt-licks, applying the field assessment and camera trapping techniques. Over all, a total of 12 different mammal species were recorded at four selected salt-licks, and then the visitation frequencies of certain species were confirmed to be significantly influenced by the seasonal variability in rainfall patterns, and also by the variations in onsite and surrounding conditions. Further research is required to validate the influences of variability in explanatory variables that were not included in this scientific study.

Published: October 2022

Las organizaciones de todos los sectores se encuentran en una lucha constante por subsistir y hacer frente a los cambios del entorno globalizado y complejo. Donde variables relacionadas con el capital humano que beneficien el desempeño se hacen relevantes para adaptarse. Bajo este escenario el propósito del presente documento es identificar la relación del aprendizaje organizacional y el desempeño, mediante una revisión sistemática de literatura dónde se establecieron criterios de selección e inclusión, así como una estrategia de búsqueda. Dentro de los principales hallazgos se destaca que los países pertenecientes a Asia se han preocupado más por las temáticas, ya que la mayoría de los artículos revisados provienen de ahí y en su mayoría cuentan con un enfoque cuantitativo. Además, algunos estudios agregaron variables como la gestión del conocimiento, innovación, liderazgo transformacional, entre otras. Se concluye que son temáticas importantes, que se han estudiado poco, además, el enfoque cualitativo y mixto, se estudiaron en menor instancia. Lo cual, una investigación de ambas variables tiene potencial de ser novedosa e interesante tanto para la academia, como para empresarios y puestos gerenciales que deseen aumentar el desempeño.
