Abstract

This paper documents the voluntary conservation practices in Patra Seroja Ecopark Forest by Indonesia’s state-owned oil and gas company, Pertamina Ltd. - Refinery Unit II Dumai, Province of Riau, west coast of Sumatera Island. The company voluntarily allocated, financed, and managed 102 hectares of land in their private area to conserve and protect its in-situ biodiversity and preserve environmental service as a secondary objective. The results of studies and assessments carried out, the management application has fulfilled the Privately Protected Area (PPA) management criteria by IUCN regarding the orientation, biodiversity, management model, and utilization. However, PPA is not recognized legally as an addition to traditionally government-led governance of conservation forests in Indonesia: KSA (Nature Reserve Area), KPA (Nature Conservation Area), TB (Hunting Park) model. Considering the potential width of Privately Protected Area application in Indonesia to support national target achievement on Convention on Biological Diversity (CBD) and Aichi 11 Target and fostering the voluntary initiatives by private in conserving biodiversity, the state may recognize the practices and initiate the legal instrument for PPA application in Indonesia.

Abstract

Persoalan penanganan banjir rob dan limpasan di Kabupaten dan Kota Pekalongan bersifat kompleks karena melibatkan banyak pihak. Kondisi ini semakin berat dengan kapasitas adaptif berada pada tingkat Rendah Sedang, dan persepsi risiko masyarakat pada level Rendah. Kajian PKSPL IPB (2021) memproyeksikan nilai kerugian dan kerusakan tahun 2030 mencapai Rp. 30,94 trilliun (penanganan business as usual). Sehingga perlu pendekatan ICM untuk mengidentifikasi solusi atas tantangan pembangunan melalui mekanisme pengambilan keputusan secara terpadu dan sistematis mulai dari perencanaan, inisiasi, implementasi, monitoring, evaluasi atas strategi dan program sebagai respon atas tantangan yang dihadapi masyarakat. Pendekatan ICM menyediakan panduan bagi semua aktor untuk menyusun rencana induk pengelolaan pesisir secara terpadu.

Abstract

Effective CO2 sequestration (SC) in rehabilitated tropical forest depends heavily on species performance and competition dynamics. This study evaluates SC potential and interspecific competition of native lowland forest tree species in Bedegung Biodiversity Park, South Sumatra, Indonesia―an area rehabilitated since 2014 through collaboration between the South Sumatra Provincial Environmental Service, National Gas Company (PGN), and IPB University. Despite the rehabilitation efforts, early planting did not consider the planting distances (Lij), impacting tree density (Dx) and individual competition index (CIi)―factors directly influencing SC. From 2020 to 2023, monitoring of tree diameter, height, and Lij data collected within a 60 × 20 m permanent plot revealed a decline in Dx from 900 ind ha–1 in 2020 to 725 ind ha–1 in 2023, primarily due increased competition. The site’s average SC reached 69.91 tCO2 ha–1 y–1, lower than mature tropical forests due to stand age. Among all species, Bayur (Pterospermum javanicum) exhibited superior SC performance, sequestering 10.02 ± 6.98 tCO2 ind–1 y–1―well above the mean―and showing increased resilience, indicaed by 1/CIi from 0.62 to 4.38. These results highlight Bayur’s exceptional role in SC under competitive pressure. For enhanced SC outcomes, management interventions such as thinning, fertilization, remove the weeds, and removing dead trees are urgently recommended. Prioritizing species with high SC potential and adaptive performance, like Bayur, is essential for optimizing carbon gains in forest rehabilitation programs.
