Abstract

A healthy community forest can provide optimal benefits for the environment and the economy, particularly in increasing farmers' income. This study aims to analyze changes in community forest health and its relationship to farmers' income in Kubu Batu Village, Way Khilau District, Pesawaran Regency. The Forest Health Monitoring (FHM) method was used to assess forest health, while quantitative analysis was employed to calculate farmers' income. Data were collected through interviews and ecological assessments in the field. The results showed a significant decline in forest health conditions from 2020 to 2024, with the average health score decreasing from 7.35 to 4.68. Additionally, a positive correlation was found between forest health and farmers' income, where better forest conditions resulted in higher income for farmers. However, the strength of this relationship slightly weakened in 2024. The decline in forest health was largely due to forest fires, which affected biodiversity and land productivity. Therefore, restoration efforts and better forest management are necessary to maintain productivity and improve the welfare of community forest farmers.Hutan rakyat yang sehat dapat memberikan manfaat optimal bagi lingkungan dan perekonomian masyarakat, terutama dalam meningkatkan pendapatan petani. Penelitian ini bertujuan untuk menganalisis perubahan kondisi kesehatan hutan rakyat dan hubungannya dengan pendapatan petani di Desa Kubu Batu, Kecamatan Way Khilau, Kabupaten Pesawaran. Metode yang digunakan adalah Forest Health Monitoring (FHM) untuk menilai kondisi kesehatan hutan serta analisis kuantitatif untuk menghitung pendapatan petani. Data dikumpulkan melalui wawancara dan penilaian ekologi di lapangan. Hasil penelitian menunjukkan bahwa terjadi penurunan signifikan dalam kondisi kesehatan hutan dari tahun 2020 ke 2024, dengan rata-rata nilai kesehatan menurun dari 7,35 menjadi 4,68. Selain itu, terdapat hubungan positif antara kondisi kesehatan hutan dan pendapatan petani, di mana semakin baik kondisi hutan, semakin tinggi pula pendapatan yang diperoleh petani. Namun, kekuatan hubungan ini sedikit melemah pada tahun 2024. Penurunan kesehatan hutan sebagian besar disebabkan oleh kebakaran hutan, yang berdampak pada biodiversitas dan produktivitas lahan. Oleh karena itu, upaya pemulihan dan pengelolaan hutan yang lebih baik diperlukan untuk menjaga produktivitas dan kesejahteraan petani hutan rakyat.

Abstract

Coastal communities have empirically utilized and proven the medicinal properties of mangrove plants. The objective of the study was to determine the species diversity of mangrove plants and their use as herbal medicine on the coast of Lampung Timur, Sumatra, Indonesia. Mangrove plant diversity was obtained through vegetation analysis and diversity index calculation. The use of mangroves as medicine was obtained through interviews and descriptive comparative analysis. The study revealed that the mangrove forest located on Lampung Timur Coastal comprises 22 species from 12 families. Out of these 22 species, 12 are true mangroves, and the remaining 10 are mangrove associates. Among the 12 true mangroves, the majority (10 species) are major mangroves, while the other two are minor. The diversity index of the Lampung Timur mangrove forest is categorized as moderate (H'= 1.9580). The use of mangrove plants as herbal medicine persists in the Lampung Timur Coastal community. Among the users of mangrove herbal medicine, the majority (55.71%) are from the older generation. Additionally, 64% of users are male, 57.37% are categorized as low-income, and 60.12% identify as Javanese based on ethnicity. The community uses various plant species for medicinal purposes. Avicennia marina is used as an antiseptic, anti-histamine, and source of vitamins. Acanthus ilicifolius is used as an anti-rheumatism and muscle ache medicine/analgesic. Rhizophora apiculata is used as an antipyretic, R. mucronata is used to increase stamina/vitality, and Soneratia caseolaris is used as an anti-cholesterol and anti-oxidant.

Abstract

Faltacaria moluccana at its early plantation, is devastated by heat and water stress due to current global climate change. Production forests in Indonesia suggested to use biochar to enhance the durability of early growth F. moluccana in the field. Empty fruit bunches (EFB), a gigantic abundant waste material in Indonesia, pose its potential as biochar feedstock. This study aims to evaluate the effects of EFB biochar on the growth of F. moluccana for one year in a field setting. The experiment used two biochar application rates (25 and 50 tons/ha) and biochar produced at two pyrolysis temperatures (400°C and 600°C). Climatic factors (rainfall and average temperature) were monitored to assess how biochar interacted with field conditions to influence the growth of F. moluccana. EFB biochar increased height and diameter increment by up to 25% and 42%, respectively, compared to control after one year. While pyrolysis temperatures show no impact on growth, biochar application rates of 25 and 50 tons/ha significantly boost diameter increments by 36% and 42%, respectively, compared to controls, without affecting height. Biochar also improves monthly growth increments under water and heat stress. EFB biochar optimizes growth under current climate conditions in Indonesia and mitigates the negative effects of extreme temperature fluctuations. Keywords: biochar, early plant growth, empty fruit bunch, Faltacaria moluccana, field experiment

Abstract

Developing cold-setting adhesives derived from waste styrofoam (WS) of expanded polystyrene foam for laminated gmelina wood involves innovative recycling of WS into functional adhesives. As a type of thermoplastic polymer, WS can be used as an adhesive at room temperature. In this study, WS was functionalized into cold-setting adhesives through dissolution and cross-linking reaction with methylene diphenyl diisocyanate (MDI) at a concentration of 40% w/v at 60°C. The mixture was then stirred at 200 rpm for 30 minutes. The adhesive is characterized by its ability to be set at room temperature, offering environmental benefits and practical applications in wood lamination. Solids content, gelation time, viscosity, cohesion strength, functional group analysis, morphological features, and curing temperature analysis were performed to characterize the cold-setting adhesives. The WS-MDI-40% had 62.4% solids content, 906.8 mPa.s viscosity, 182.3 Pa cohesion strength, and 197.8 minutes of gelation time at room temperature. The adhesion performance was evaluated in laminated wood using gmelina wood at glue spread rates of 250 and 300 g/m2 and cold-pressed at various durations. The block shear strength value of laminated wood bonded with WS-MDI-40% at 300 g/m2 and cold-pressed for 24 hours was higher than that of other samples, reaching 8.2 MPa, which met the Japanese Agricultural Standard (JAS No. 234) for glued laminated timber, exceeding the minimum requirement of 5.4 MPa. Fourier transform infrared (FTIR) spectroscopy revealed that the cold-setting WS-MDI-40% were cross-linked via urethane linkages (R–NH–COO–R). The free –N=C=O groups could react with the –OH groups of gmelina wood to produce laminated wood during cold-pressing. This study suggested a recycling alternative of WS into a cold-setting wood adhesive for laminated wood, which can be utilized in interior applications. Keywords: adhesive, block shear strength, cohesion strength, cold-setting, gmelina wood

Abstract

Laser technology has become one of the main innovations in material delivery, especially in the wood industry for cutting and engraving purposes. One of the advantages of this technology is the ability to produce precise and aesthetic patterns on the wood surface. However, each type of wood has unique characteristics to the heat treatment of the laser beam, so further research is needed to understand the specific response of each type of wood. This study aims to trigger the effect of variations in CO₂ laser power on changes in the surface color of cempaka wood (Michelia champaca) and to identify consumer preferences for the color results. The study was conducted at the Forest Products Technology Laboratory, University of Lampung, using three variations of laser power: 2.5 watts, 5 watts, and 7.5 watts, with each treatment repeated three times. The surface color was described using a CIE-Lab system-based colorimeter (parameters L*, a*, and b*) before and after engraving. In addition, a consumer preference survey was conducted boldly involving 100 students from the University of Lampung to assess the visualization of the engraving results. The results showed that higher laser power (7.5 watts) produced darker and more contrasting wood colors, with a decrease in L* values and an increase in a* and b* values. Most respondents preferred the results of engraving using 7.5 watts of power because it produced darker colors and was considered more aesthetic and gave sharper results.

Abstract

friendly material. Two local Indonesian bamboo species, namely apus bamboo(Gigantochloa apus) and ater bamboo (Gigantochloa atter), have been widelyused in various fields but still face challenges such as fading color and lowresistance to moisture. This study aims to investigate the color changes in apusbamboo and ater bamboo after undergoing heat treatment using oil at varyingtemperatures of 160°C, 180°C, 200°C, and 220°C. Five-year-old bamboo sampleswere cut into cylindrical shapes with a diameter of 10 cm and a height of 5 cm,then tested for color before and after the heat treatment. The treatment was carriedout for 2 hours using oil as a medium, then dried in an oven. Color changes wereanalyzed using a general colorimeter scanner. Data collection on communitypreferences for bamboo colors was conducted by distributing questionnaires. Thered-green chromaticity changes in apus bamboo exhibit a decreasing trend,whereas ater bamboo shows an increasing trend. The yellow-blue chromaticitychanges in both bamboo species show an increasing trend. For the lightness level,both bamboos have decreased. The overall color change in apus bamboo and aterbamboo increases with the increasing temperature. The color preference resultsrevealed that women prefer bright colors in both bamboo species. Men are moreselective in their color preferences; some choose bright colors, but many alsochoose dark colors.

Abstract

This study explores the effects of pyrolysis temperature of shorea wood biochar and its doses on the soil properties and biomass of Falcataria moluccana seedlings. The focus is optimizing pyrolysis temperatures (400°C and 600°C) and biochar doses (0%, 25%, and 50%) to enhance soil fertility and seedling biomass. Both pyrolysis temperature and biochar dose are critical factors that influence the soil properties, directly affecting its effectiveness as a soil amendment. The research was conducted as a controlled greenhouse experiment over 120 days; each treatment was replicated 15 times. We observed several soil chemical properties, including pH, cation exchange capacity (CEC), organic carbon (C-organic), total nitrogen (N-total), and total phosphorus (P-total). The growth parameters assessed included above ground biomass (AGB), below ground biomass (BGB), total biomass (TB), and root to shoot ratio (R:S). Data analysis involved one-way and two-way ANOVA. Results indicated that soil properties, particularly cation exchange capacity (CEC) and organic carbon content, were improved, thereby enhancing soil fertility. However, ANOVA indicated no statistically significant differences across treatments. Biochar significantly enhanced above-ground and below-ground biomass (AGB and BGB). Nevertheless, both pyrolysis temperature and biochar dose independently influenced biomass accumulation in F. moluccana seedlings. The highest increases were observed in the treatment with the highest pyrolysis temperature (600ᵒC) and the highest dose (50%), which led to an 85% increase in AGB and a 60% increase in BGB compared to the control. Based on the study, Shorea wood biochar, particularly when used at 600°C and 50% dose, significantly improves soil fertility and seedling growth, providing a promising approach for developing F. moluccana plantations.
