Abstract

Acacia crassicarpa is an important species for industrial plantation forestry, but a portion of tissue-cultured plantlets fail to develop functional roots during acclimatization. This study evaluated the effects of leaf type and ex vitro rooting hormone application on growth and physiological responses of non-rooted plantlets. A RCBD was applied with two factors: leaf type (pinnate, phyllode, and pinnate–phyllode) and rooting hormone concentration (0, 500, 1000, and 1500 ppm of IBA and NAA). Parameters observed included stomatal conductance, photosynthetic rate, and seedling height. Results showed that leaf type significantly affected stomatal conductance and early seedling height, but had no significant effect on photosynthetic rate or later growth stages. Rooting hormone concentration and its interaction with leaf type were not significant for all parameters. Early seedling performance was primarily influenced by initial leaf type, while growth was largely constrained by the limited root system of non-rooted plantlets rather than hormone application.

Abstract

Oil palm cultivation is generally carried out in monoculture. This has an impact on decreasing soil fertility, one of which is the physical properties of the soil. One of solutions that can be done to overcome this is the cultivation of oil palm plants with an agroforestry system. The purpose of this research was to compare the physical properties of soil agroforestry on oil palm (Elaeis gueneensis Jacq.) and aloes (Aquilaria malacensis Lamk.) with oil palm in monoculture. This research was conducted in Bukit Kemuning Village, Tapung Hulu District, Kampar Regency for 4 months from November – Februari 2020. Determination research the locations for agroforestry system and monoculture system using purposive sampling method. Soil samples were taken from 4 sampling point: palm circle, leaf frond piles, harvest path and aloes circle which were repeated 6 times on each land. The observation parameters are several soil physical properties (topsoil depth, bulk density, particle density, total pore space, moisture content, water holding capacity, permeability, infiltration, and soil resistance) and soil C-organic. Data from the observations of each parameter were analyzed statistically using the t test. The results showed that the agroforestry system increased C-organic content and improved selected soil physical properties (increase topsoil depth, total pore space, moisture content, water holding capacity, permeability, infiltration and decrease bulk density, particle density and soil resistance).

Abstract

Indonesia has the largest areas of tropical peatland, which is becoming vulnerable to fires. Smoke haze crises due to forest fires that occur annually have plagued many parts of Southeast Asia between 2013-2015 with devastating effects on human health and economy. Fires spread fast on island peatlands in eastern Sumatra because their small catchments drain quickly into the sea. This research dived into the spatial and temporal patterns of peat wildfires in the Peat Hydrological Unit of Bengkalis Island. Drawing on remote sensing sources such as MODIS-C6 Terra/Aqua thermal hotspots from 2001 to 2020 and Landsat images, the findings revealed two clear yearly fire peaks in Bengkalis: Period I (January-March) and Period II (June-August). Hotspot density was concentrated in deep peat areas 57.3% of detections are from the 500-700 cm thickness class, and 93.1% from peat >300 cm. During 20 years, 343 fire-days burned a total of 56,202 ha; the largest single occurrence involved a burnt area of 19,999 ha in 2014. Monthly rainfall is the dominant climatic control, exhibiting a clear inverse relationship with hotspot frequency; rainfall below 100 mm/month defines elevated fire-risk conditions. These findings establish that MODIS hotspot monitoring combined with Landsat burned area mapping provides a robust long-term fire assessment framework, and that rainfall thresholds offer a practical operational basis for fire early warning systems on island peatlands.

Abstract

Utilizing coconut waste, particularly shells and husks, as raw material for charcoal briquettes holds great potential for supporting environmentally friendly and sustainable renewable energy. However, this waste is still not being utilized optimally, even though it can reduce environmental pollution while providing economic benefits. This study aims to evaluate the effect of varying the mixing ratio of coconut shells and husks on the physical characteristics and performance of the resulting charcoal briquettes, as well as to determine the optimal composition as an alternative energy source. The research was conducted at the Forestry Laboratory of the Faculty of Agriculture, Universitas Riau, over a five-month period (August–December 2025). The raw materials consisted of coconut shells and husks with three composition variations: 100% shells, 75% shells + 25% husks, and 50% shells + 50% husks. The carbonization process was performed conventionally for one hour. Afterward, the charcoal was ground, mixed with arpus binder, molded, and tested for briquette characteristics such as moisture content, density, and calorific value. The results showed that the 100% coconut shell briquette had the lowest moisture content (6.51%) and the highest density (0.79 g/cm³), resulting in more efficient, stable combustion and a high calorific value. Conversely, increasing the proportion of coconut husk raised the moisture content to 16.58% and lowered the density to 0.66 g/cm³, which negatively impacted briquette quality. Low moisture content and high density are key indicators of good briquette quality. In conclusion, a briquette formulation dominated by coconut shells is recommended for producing high-quality charcoal briquettes as an environmentally friendly and sustainable source of renewable energy, as well as supporting optimal coconut waste management in Riau Province and surrounding areas.

Abstract

Penelitian ini mengevaluasi performa fenotipik, potensi genetik relatif, dan seleksi progeni Bush Merah (Lophostemon suaveolens) umur lima tahun di lahan gambut Kabupaten Siak, Provinsi Riau. Penelitian menggunakan uji progeni half-sib dengan rancangan acak kelompok yang terdiri atas 45 progeni, empat ulangan, dan lima pohon per plot, dengan blok yang merepresentasikan strata muka air tanah 20-25, 26-30, 31-35, dan 36-40 cm. Evaluasi genetik dilakukan menggunakan model linier campuran dengan pendekatan Best Linear Unbiased Prediction (BLUP). Nilai survival rerata mencapai sekitar 88%, yang menunjukkan adaptasi awal yang baik pada lahan gambut. Nilai heritabilitas sempit tergolong rendah pada tinggi total (H60; h² = 0,0473), diameter setinggi dada (D60; h² = 0,0472), dan mean annual increment (MAI; h² = 0,0342), sehingga variasi pertumbuhan dan produktivitas lebih kuat dipengaruhi heterogenitas lingkungan daripada komponen genetik aditif. Seleksi multi-sifat berbasis BLUP mengidentifikasi LS17, LS40, LS15, dan LS43 sebagai kandidat utama pada jalur produktivitas-adaptasi, sedangkan LS23, LS32, LS10, dan LS27 menonjol pada jalur kualitas kayu-adaptasi. Kerapatan kayu berada pada kisaran 502,65-742,86 kg m⁻³. Hasil ini menunjukkan bahwa L. suaveolens berpotensi dikembangkan sebagai spesies alternatif bahan baku pulpwood di lahan gambut melalui seleksi yang mengintegrasikan adaptasi, produktivitas, dan mutu kayu.

Abstract

Kuala Tolam Village, Pelalawan Regency, Riau Province, is one of the regions that still possesses significant peatland forests, which are ecologically, socially, and economically important. However, pressures from plantation expansion, land conversion, and limited community knowledge about forest functions have made this area vulnerable to degradation. This community service activity aimed to enhance public knowledge of the importance of forests. The method employed was socialization through an educational, participatory, and interactive approach combined with small group discussions. The respondents in this activity were stakeholders involved in community deliberations with the Siak Pelalawan Landscape Program in the context of forming a collective commitment to maintain forest functions and areas. The results of this activity showed an increase in community knowledge about forest functions as measured by several aspects, namely forest definition, forest types, and forest functions. Community understanding of the definition of forests increased by 39%, knowledge of forest types around Kuala Tolam Village increased by 36%, and knowledge of forest functions increased by 30%. These findings indicate that the socialization and educational approaches applied were successful in raising public awareness of the importance of forests in supporting the community’s commitment to preserving forest functions and areas. Furthermore, the formation of such commitment, supported by enhanced knowledge and understanding, is expected to serve as a strong foundation for establishing a forest patrol and monitoring team in Kuala Tolam Village, Pelalawan Regency.

Abstract

Leaf pruning is often used to suppress transpiration, but experimental evidence in Eucalyptus suggests that reducing leaf area is not always necessary and can reduce seedling performance. This study aimed to evaluate the effect of leaf pruning on the survival and early vegetative growth during the seedling phase of Eucalyptus pellita F. Muell. This study used an experimental approach, using a completely randomized design (CRD) with 4 treatments and 5 replications. The results showed that the effect of leaf pruning on the growth of Eucalyptus pellita seedlings resulted in good average growth in vegetative growth parameters, such as normal plant life at 21 days after planting (DAP), plant height, stem diameter, number of leaves, seedling recovery rate, and root volume. This indicates that the presence of intact leaves plays an important role in supporting the process of photosynthesis, carbohydrate accumulation, and distribution of assimilates to growth organs, thereby increasing seedling vigor. On the other hand, root length and root dry weight did not show any significant effect, due to the presence of a root growth limiting factor, namely the tube, so that the roots could not grow to their maximum length (the roots only surrounded the tube position). The conclusion is that there is an effect of the treatment without leaf shears on the survival success and initial vegetative growth during the nursery phase of Eucalyptus pellita F. Muell.

Abstract

This community service activity aimed to improve the knowledge of residents of Kuala Tolam Village regarding drought control, flood management, peatland ecosystems, and riverbank landslide mitigation in areas vulnerable to hydrometeorological hazards. The education program was conducted through material delivery, discussions, and pre-test and post-test evaluations using a questionnaire. Data were analyzed using IBM SPSS Statistics 20 to describe respondent characteristics and to examine knowledge improvement using a paired sample t-test. The results showed that 66.67% of participants were initially in the low knowledge category; however, after the intervention, all participants improved to the moderate and high categories. The mean knowledge score increased from 47.33 to 69.73, with a statistically significant difference (p 0.05). This improvement was supported by the relevance of the materials, including peatland hydrology, drought control, flood mitigation, and riverbank bioengineering. Participatory education is therefore important for strengthening community capacity and village preparedness in managing environmental risks in peatland ecosystems.
