Abstract

Sangatta as the capital of East Kutai Regency is a rapidly growing urban area. The rapid growth and development of Sangatta resulted in the increase of open space. For this reason, the government and local communities tried to reforest the residential areas by planting many plant species. However, generally the chosen species were not the local ones and tended to be chosen based on the easiness of cultivation and aesthetic aspects. The popular species is janti (Sesbania sesban), which can be called as an alien species because of the lacks of records and information about its existence. The alien species spreading freely and uncontrolled could be potentially invasive. To prove it, an assessment needed to be held. One of procedure that can be used is assessment protocol issued by the nature serve organization, which determines the presence of an invasive type or species based on I-rank, which consists of four assessment categories, namely ecological impact, distribution status and abundance, distribution trends and abundance, and management difficulties. The research result showed that the presence status of Janti was invasive in the middle rank.

Abstract

Fifty samples of raintree from Sangatta, the capital city of Kutai Timur Regency, East Kalimantan were analyzed using isozyme markers to determine the characteristics of the banding pattern. The use of isozymes was intended as a biochemical marker for genetic diversity analysis. This study aimed to determine the enzyme system that could be used to determine genetic diversity of raintree. The enzyme systems used were diaphorase, esterase, and peroxidase. Polymorphism assessments were carried out on the parameters of expected heterozygosity (H), polymorphism information content (PIC), effective multiplex ratio (E), marker index (MI), discriminanting power (D), and Resolving (R). Among the three enzyme systems used, diaphorase showed consistent performance against each of the parameters assessed, with a value of H =0.475; PIC = 0.362; E =6.1; MI = 2,2; D = 0.63: and R = 4.44. However, esterase had the highest multiplex effective ratio (E = 6.16). Therefore, diaphorase is the best isozyme marker that can be used to analyze the genetic diversity of raintree.

Abstract

The Covid-19 pandemic has resulted in several government-related activities being carried out online. One of them was a public consultation on the development of the Taman Botani Kutai Timur. This activity aimed to find out the recent conditions and potential developments that can be reached from Taman Botani as a green open area. The activity was carried out through focus group discussions, presenting researchers and practitioners from parties representing the central government, provincial governments, district governments, relevant government institutions, academics, community institutions, and other interested communities. The meetings held revealed that Taman Botani has potential to be developed for the better. One of the suggestions that emerged was to develop it into a regional botanical garden. Otherwise, its successful development requires a strong commitment from the local government regarding policy formulation and funding allocation. In addition, the development of Taman Botani requires monitoring from the community in the form of policy advocacy.
