Abstract

The history of nickel mining in Indonesia began in the Verbeek Mountains in Sulawesi in 1901. The finding of nickel and its extraction occurred in the Netherlands, making it the pioneering site for this ore. Also, the substantial rise in the extraction of natural resources like nickel through mining would inevitably profoundly influence forests, which serve as the core of the ecosystem for both flora and fauna. This study aims to determine the consequences of the growing nickel production on Indonesia’s forests and environment. It involves examining the alterations in the forests due to the increased nickel production and evaluating the broader environmental effects. The research method used in this research is a literature review. This technique seeks to analyze, assess, and interpret diverse research findings to examine them within the investigated subject’s framework. The research result of this investigation demonstrates that the escalating nickel production in Indonesia is detrimental to forests and the environment, leading to deforestation, degradation of habitats, and contamination of the air and soil. These alterations present immediate hazards to human well-being, such as respiratory problems and effects on agricultural output. It is crucial to evaluate and improve the methods used for nickel production and adopt sustainable management strategies to reduce the negative impacts on the environment and protect both the ecosystem and human welfare. Keywords: ecosystem pollution, deforestation, forest management, nickel mining, water pollution

Abstract

The Hydrologic Engineering System-River Analysis System (HEC-RAS) model is a model that can display water surface cross-sections in both 1D and 2D forms. That way, HEC-RAS can predict the amount of peak discharge that results in flooding. This study aims to see the distribution of flood areas in the Paremang Watershed as a basic form of mitigation activity for flood events. A flood disaster analysis was conducted using the HEC-RAS model. The HEC-RAS model data includes river water discharge data from the Soil and Water Assessment Tools (SWAT) analysis, which is an overlay of topography, land cover/use, soil characteristics and climate data from authorized agencies, and direct field observations. The results showed that the flood area was 2,722.38 ha, affected by high rainfall conditions, steep slopes accelerating water flow, and land cover dominated by rice fields, bushes and dry land agriculture. The condition increases surface flow, stimulating the amount of water discharged. This resulted in flooding in most of the downstream and middle areas of the Paremang Watershed in Luwu Regency. Therefore, mitigation in the form of land use planning is needed. The plan is led by the Ministry of Agrarian Affairs and Spatial Planning, which includes other sectors ranging from forestry, agriculture, fisheries, tourism, and public works. This could support in developing policies ranging from forest rehabilitation, social forestry, community forests, expansion of agroforestry patterns, ecotourism development, and flood mitigation such as technical buildings. Keywords: flood areas distribution, HEC-RAS model, Paremang, soil and water assessment tools, watershed

Abstract

Tannin is a major polyphenolic secondary metabolite widely distributed in the forestry sector and can be added to polymer matrices to manufacture bioactive films for food packaging. Tannins have functional properties as antioxidants, antibacterial, and anti-inflammatories. Tannins are classified into two types, namely condensed tannins and hydrolyzable tannins. Tannins have been used primarily in food, wood, leather, pharmaceutical, and other industries. In the food industry, tannins are used to develop food packaging, preservation, and the function of the food industry. Tannin molecules have the advantage of combining with polymers or polymer surfaces, for example, synthetic polymers, biopolymers, and micro- and nano-sized fibers, which will form new products whose physical and chemical properties increase in functional properties because of the presence of hydrophilic and nucleophilic groups. Combining tannins with a polymer can be done by one-step reactive extrusion, layer by layer, dynamic vulcanization, acetylation, and in situ extraction methods. This paper describes general information about tannins, followed by applications using tannins, tannin-based hybrid materials, and methods of combining tannins with a polymer for food packaging purposes. Keywords: active packaging, bioactive film, polymer, secondary metabolite, tannins

Abstract

Mangroves are coastal ecosystems with different abilities to adapt to changing environmental conditions. Habitat characteristics that continue to change cause morphological, anatomical, and physiological adaptations of mangrove species. This study aims to observe the survival and growth rate of Rhizhopora mucronata in Peunaga Cut Ujong, Meurebo, West Aceh. The mangroves were planted in 2022 and observed one year after planting. The observation and data collection of 35 tree samples were conducted every two weeks. The results showed a decrease in the survival rate from the third month of observation until the end, showing a decrease of 78%. In contrast, tree growth increased from months 1 to 5. Salinity conditions and substrates dominated by sand with minimal nutrients indicate adaptation to the growth of some relatively small mangrove species. Fluctuating salinity conditions with the dominance of sand have the potential to support the survival of R. mucronata, although with low growth. Its main influence still needs to be studied over a longer period. Keywords: adaptations, growth, morphometrics, salinity

Abstract

Birdwatching focuses on observing wild birds. Nevertheless, previous studies were still focused on the supply aspect. Meanwhile, the demand aspect is still limited, including in Indonesia. Furthermore, understanding birdwatchers’ preferences can lead to market segmentation. Therefore, this study aimed to analyze the preferences of Indonesian birdwatchers towards location, bird targets, and buddies. Data on the demographics and preferences of Indonesian birdwatchers were collected from 1,203 respondents using an online questionnaire. Data were analyzed using Chi-Square and the Generalized Linear Model. The results revealed that most respondents prefer destinations outside the biogeographic region, with Papua being the most preferred location. Overall, birds of the Paradisaeidae family were chosen by the largest number of respondents, followed by the Accipritidae family. Variables that significantly influence the preference of birdwatching destination based on the distance taken, age, domicile, income, organization, and expertise of the birdwatchers. Locations that are further away attract young respondents who live in urban areas, have higher incomes, are members of organizations, and have high birdwatching skills. The bird species and locations preferred by the birdwatcher can be used as a basis for developing birdwatching destinations according to the birdwatcher’s preferences. Keywords: bird, birdwatching, demographic, location, preference

Abstract

Balla Lompoa Ri Galesong, known well as the traditional house of the Takalar Regency, South Sulawesi, has become a historical building in Indonesia.  Nowadays, it still functions as a residence for the royal family, a repository for historical artifacts, and a venue for annual cultural performances. Maintaining and protecting buildings from damaging factors is crucial to maintaining their life and function. This research focuses on detecting the damage characteristics of wooden parts of buildings, identifying biological deterioration agents, and assessing the level of infestation. Data collection uses the visual detection method. The results showed that the activities of biodeterioration agents, namely subterranean termites (Microcerotermes serrula), drywood termites (Cryptotermes), powder-post beetles, wood-staining fungi, and wood-decaying fungi found on pillars, windows, doors, walls, floors, and ceiling. Most pillars are targets of attacks by wood-destroying organisms, characterized by the highest attack intensity (70.13%) and the moderate category in the degree of attack (50–74). Understanding and mitigating the damage to historic buildings is critical for implementing effective preventive measures. Keywords: Balla Lompoa Ri Galesong, biodeterioration agents, cultural heritage, wood biodeterioration

Abstract

Biopellets from gamal wood (Gliricidia sepium) as a biomass energy resource could be an alternative to replace fossil fuels due to having met standards based on moisture content, ash content, fixed carbon, calorific value, and density. Unfortunately, they still had high levels of volatile matter. Robusta coffee husk was a material with high nitrogen content, which is suspected of being able to bind aromatic substances in volatile organic compounds. This study aims to evaluate the quality of biopellets and determine the optimum composition of the biopellets from gamal wood and coffee husk. The blended composition of gamal wood and coffee husk biopellets studied were 100:0, 75:25, 50:50, 25:75, and 0:100. The biopellets were manufactured using the material size of 40-60 mesh with a pressure of 173.51 MPa. The best biopellet was produced in the composition of 75% gamal wood and 25% coffee husk, with a density of 0.85 g/cm3, moisture content of 8.03%, ash content of 3.92%, volatile substances of 78.01%, fixed carbon of 18.07%, and calorific value of 4,176 cal/g. The biopellet quality met the standards of SNI 8021:2014 and EN 14061-2, except for ash content. Adding coffee husk reduced gamal wood biopellet’s volatile matter, increasing the fixed carbon and density of gamal wood biopellets.

Abstract

Sengon (Paraserianthes falcataria L. Nielsen.) and jabon (Anthocephalus cadamba Miq.) are fast-growing wood of low quality. This study aims to overcome the disadvantages of low-quality wood via impregnation using monoethylene glycol (MEG), and nano-silica synthesized from betung bamboo stems (Dendrocalamus asper). Nano-silica was obtained by the ultrasonication method, with the average size and zeta potential at 93 nm and -44.21 mV, respectively. This study used five different solutions: untreated, 50% MEG, MEG-Silica 0.5%, MEG-Silica 0.75%, and MEG-Silica 1%. The impregnation process began when a vacuum of 0.5 bar was applied for 60 minutes and continued with a pressure of 2.5 bar for 120 minutes. The results showed that sengon and jabon experienced an increase in quality as seen from the parameters of weight percent gain, specific gravity, modulus of elasticity, modulus of rupture, hardness, color brightness, and durability against dry wood and subterranean termites. Besides, the strength and durability classes of both kinds of wood also improved to III and IV, respectively, with the solution’s concentration gradually increasing. Based on the results, MEG-Silica 1% is the most influential solution in improving the physical-mechanical properties and durability of sengon and jabon wood.

Abstract

Cinnamomum burmanni (Lauraceae) is one of the Cinnamomum species native to Indonesia. Given the worldwide use of cinnamon, the famous spice derived from its bark, cinnamon is also considered to possess medicinal properties. Consequently, a comprehensive review of C. burmanni was conducted to explore its medicinal benefits. This paper reviews several studies on the traditional use of C. burmanni in Indonesia, its phytochemistry, and its pharmacological properties. Traditionally, C. burmanni is utilized not only as spices but also for medicinal purposes, food ingredients, and ritual purposes. The bark is the most commonly used part, while few other parts of the plant are used. Several phytochemical compounds of C. burmanni have been identified. C. burmanni also has been reported to exhibit a wide range of biological activities. From those studies, it can be concluded that the medicinal use of C. burmanni’s bark has been scientifically validated due to its rich content of active compounds. Furthermore, other parts of C. burmanni should be analyzed to determine their content of active compounds. Keywords: active compound, Cinnamomum burmanni, medicinal plant, spice, traditional medicine

Abstract

Waqf-based forest is developed on waqf land and is now being developed in Indonesia. It combines Islamic principles with environmental conservation, as being waqf assets, a forest is prohibited from being sold, given, or inherited. An effective management strategy is crucial to ensure waqf-based forest productivity and sustainability. Some research has already been conducted, but the specific dimension remains unexplored. This study aims to identify essential aspects and effective management strategies to escalate waqf-based forest benefits. Using a comprehensive approach, this study combines a literature study, in-depth interviews, and a study case in Bogor Waqf Forest, Bogor Regency, Indonesia. The findings were analyzed using the Analytic Hierarchy Process (AHP), followed by Focus Group Discussion (FGD) and further in-depth interviews as the validation process. There are six important considerations to optimize waqf-based forest management: legal, ecological, Islamic, economical, social, and aesthetic. The land’s legal status as waqf assets is recognized as the most crucial aspect to avoid possible conflict and sustainability in the future. Then, the following considerations are improved ecological and Islamic activities aspects, economic strategies, and social and aesthetic consecutively. This research is expected to provide a deeper investigation of the future management strategies for waqf-based forests. Keywords: agroforestry, analytic hierarchy process, management, sustainability, waqf-based forest
