The Role of Media in Agenda Setting: Environmental Impact Discourse of Indonesian Palm Oil Industry

2026-01-06T07:14:26+00:00

Environmental management in Indonesia's palm oil industry has long been a topic of public discourse. While the industry contributes significantly to the national economy through economic growth, job creation, and rural development, it is often associated with environmental degradation. The media plays a critical role in shaping public perception and influencing policy agendas through issue framing. This study aims to analyze the differences in the framing of environmental issues related to the palm oil industry at various media levels (international, national, local, and NGO media). The study used a content analysis method on 470 news articles published between 2014-2023, using the Media Coverage Review approach and a categorization system based on issue themes and cause attribution. The results of the analysis show that there are significant differences in the causes and emphasis of issues between media types. International media and NGOs tend to associate the palm oil industry with deforestation, while national media highlight other sectors' contributions to environmental degradation. This discrepancy reflects an information gap that can influence the process of evidence-based policy formulation. These findings emphasize the importance of harmonizing media information to support fair and sustainable policy-making in the palm oil sector.

Best linear unbiased prediction (BLUP) is a method designed to predict genetic values from imbalanced data. BLUP analysis that utilizes kinship information can reduce bias due to data imbalance. This study aimed to estimate genetic parameters and general combining ability of parents through progeny testing and validation of prediction models for untested crosses. A progeny testing was planted in 2008 in a randomized complete block design with 5 replications. Observations were made on 10 characteristics observed in 2015 - 2017. The results showed that mesocarp/fruit and kernel/fruit characteristics were more controlled by tenera parents. Based on the estimation of the general combining ability of dura parents, BJ5686D and BJ5678D can be used to produce varieties with superior characteristics of productivity and oil yield. Tenera parent, AP141T can be used to produce superior varieties with good oil-related traits. The BJ5819T and BJ5817T parents can be used to produce varieties with slow height increment and high oil-related traits. Special combining abilities were not significant for all characteristics. The results of the 2-fold cross-validation showed that the accuracy for number of bunch , fresh fruit bunches, CPO production, rachis length, core/fruit, dry oil/mesocarp, and oil/bunches was 0.52 – 0.88. This information can be utilized in subsequent breeding programs.

Growth Response of OiI PaIm (EIaeis guineensis Jacq.) in the First Year of Mature Phase to the AppIication of OiI PaIm Empty Fruit Bunch Compost and Humic Acid

The excessive use of chemical fertilizers can damage ecosystems and reduce soil fertility, negatively impacting crop production. The addition of organic materials to the soil, such as empty fruit bunch (EFB) compost and humic acid, can mitigate these negative effects. The nutrient content in EFB compost can enhance plant growth, while humic acid can improve nutrient absorption by plants. This study aimed to determine the optimal combination of EFB compost and humic acid doses for achieving the best growth of mature phase oil palm in its first year of production. The research was conducted at the Ciparanje Experimental Farm, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, from February to June 2024, using a randomized block design (RBD) with four treatments and six replications. The treatments tested were: 2.5 kg/plant of NPKMg fertilizer (12:12:17:2); 50 kg/plant of EFB compost; 30 kg/plant of EFB compost + 300 mL/plant of humic acid; and 10 kg/plant of EFB compost + 300 mL/plant of humic acid. The results showed that, in general, there were no significant differences in most growth parameters observed. Significant differences were only found in the number of fronds, particularly at 2 and 4 weeks after treatment (WAT), with the application of 10 kg/plant of EFB compost + 300 mL/plant of humic acid yielding the best results.

Optimization of Microcrystalline Cellulose Production from Oil Palm Empty Fruit Bunch Cellulose Using Response Surface Methodology

2026-01-06T07:11:33+00:00

Oil palm empty fruit bunches (OPEFB) are abundant biomass waste with high cellulose content, yet their utilization is limited to conventional applications such as mulch in palm oil plantations. However, OPEFB can be potentially developed into high-value derivative products, such as microcrystalline cellulose (MCC), which has widespread applications across various industries, including pharmaceuticals, food, and composite materials. This study aims to optimize MCC production from OPEFB cellulose through acid hydrolysis using the Response Surface Methodology (RSM) approach to achieve the highest yield. Optimization was conducted on three main variables: hydrochloric acid (HCl) concentration (1, 2, 3 M), hydrolysis time (20, 40, 60 minutes), and the mass ratio of cellulose to HCl volume (25, 50, 75 g/L), using a Box-Behnken experimental design. The results showed that the highest MCC yield of 84.41% was achieved at an HCl concentration of 1.77 M, a hydrolysis time of 36.57 minutes, and a cellulose mass ratio to the HCl volume of 58.33 g/L. The MCC obtained under optimal conditions has an alpha cellulose content of 71.42%; hemicellulose 14.36%; and lignin 0.59%. Fourier Transform Infrared (FT-IR) and X-Ray Diffraction (XRD) analyses confirmed spectral profiles and crystallinity consistent with typical MCC. The results demonstrate that production optimization using RSM successfully improved MCC production efficiency with high yield and cellulose content.

Bird Diversity in Oil Palm (Elaeis guineensis Jacq.) Plantation Landscapes as a Conservation Model

2026-01-06T08:22:56+00:00

Data and information on avian species diversity in oil palm plantations in West Sulawesi remain limited. This study aimed to investigate the diversity of bird species found in an oil palm plantation landscape located in the Minti Watershed, Pasangkayu, West Sulawesi. The bird community was surveyed using the point count method at 126 stations distributed across eight sites representing different habitat types: secondary forest (4 sites), oil palm plantations (2 sites; managed by a company and local communities), and riparian areas (2 sites). The similarity in species composition among the survey stations was analyzed using the Bray-Curtis similarity index and visualized with Non-metric Multidimensional Scaling (NMDS). A Kruskal-Wallis test was employed to compare the number of individuals and species among the sites. A total of 82 bird species from 36 families were identified within the Minti Watershed's oil palm landscape. Secondary forests exhibited the highest species diversity and abundance, while oil palm plantations were dominated by insectivorous bird species. Cluster analysis and NMDS results indicated that habitat type significantly influences bird species composition. Forest fragments and riparian habitats are crucial for supporting bird diversity in the Minti Watershed's plantation landscape. Therefore, bird conservation strategies in this region should adopt a multi-habitat approach that integrates the management of secondary forests, oil palm plantations, and riparian zones.
