Abstract

This study aims to determine the diversity of insects in the protected forest area of Kota Nona Ambon, as well as the diversity, abundance, and distribution of insects in the area, in order to detect the quality of forest health early. In general, this study employed a sample extraction method. An observation path was created using an inventory method to collect insect data, with a width of 20 meters and a span of 100 meters, and a distance of 10 meters between paths. Data collection on attacks was then carried out. Insects were collected directly, and pitfall traps were set at a distance of 10 meters. Another type of trap was then installed at the next 10 meters along the path. Plots measuring 20 m x 20 m were created on each insect observation path. There are 13 types of insects found in the Gunung Nona forest area, with a total of 185 individuals in 8 orders, namely Diptera, Lepidoptera, Coleoptera, Aranae, Odonata, Spiroboliida, Hymenoptera, which are spread across 10 families, namely: Callipholidae, Nymphlidae, Pieridae, Muscidae, Culicidae, Araneidae, Alydidae, Libellulidae, Scarabaeidae, Erebidae, Fomicidae.

Abstract

The research was conducted in the Sirimau Protected Forest area of Ambon Island from June to October 2024. Several forms of damage in the protected forest are Konk, Cancer, Damage to leaf shoots or shoots, Broken or dead branches, Open Wounds, Termite Attacks, Liana, Brum, Moss, Broken Rod, and Leaves Discoloration. The damage to the Sirimau Protected Forest has caused serious ecological impacts, particularly the decline in the forest's ability to serve as a primary water catchment and absorption area for Ambon City. This has implications for increasing the risk of hydrometeorological disasters, such as flash floods and landslides in downstream areas, and threatens the sustainability of clean water supplies for residents.

Abstract

Rice consumption in Nigeria has grown tremendously over a few decades, particularly among urban dwellers. The country also ranks first as both producer and consumer of rice in the West African sub region. Consumption is expected to continue to increase with population growth, urbanization and changes in consumption habits. This study investigated the influence of rice attributes on price. A total of 156 rice samples were collected from 15 markets within the radius of 400 km from the site of Middle Rima River Valley Irrigation Scheme in Nigeria, which were analysed for grain physical and chemical quality characteristics, which were subjected through a hedonic price analysis of different rice types sold in the markets. Results show that some markets had significant discount effect on price of rice while consumers pay premium price on imported rice. These findings suggest that the consumers preferred rice more appealing physical attributes such as low percent broken, high length to width ratio, low varietal mix and low impurities. This is despite the nutritional ascendance, demonstrated by high amylose and protein contents of domestic rice over the imported. The wide price differentials between domestic and imported rice could be bridge with improvement in the physical attributes of domestic varieties and better post-harvest handling techniques to reduce brokenness and impurities of the domestic rice. There is also need for advocacy of the nutritional in order to narrow the gap in consumer’s preference towards the domestic rice.

Abstract

This study aims to identify the potential and dominance patterns of Non-Timber Forest Products (NTFP) species in the Waesala Village Forest Area, Huamual Belakang District, West Seram Regency. Based on the research results, this area has NTFP potential from four main families, namely Arecaceae, Myrtaceae, Annonaceae, and Fabaceae. Among these species, Melaleuca cajuputi is absolutely dominant with an Important Value Index (IVI) of 162.3% at the tree level, 181.9% at the pole level, 143.9% at the stake level, and 168.5% at the seedling level. The species diversity (H’) in this area is classified as low, with the highest value at the tree level (H’ = 0.4669) and the lowest at the seedling level (H’ = 0.2644). This indicates that natural regeneration of other species is very limited due to the dominance of Melaleuca cajuputi. The distribution of individuals among species (E) is most even at the pole stage (E = 0.3186), while the seedling stage has the lowest evenness (E = 0.1907), emphasizing the dominance of a single species at this stage. The dominance index (C) shows the highest value at the seedling stage (C = 0.718), indicating the absolute dominance of Melaleuca cajuputi during this phase, with lower values at the stake stage (C = 0.535), pole stage (C = 0.443), and tree stage (C = 0.364). Several factors contribute to the dominance of Melaleuca cajuputi, including rapid regeneration ability, effective dispersal, adaptation to extreme environmental conditions, as well as human intervention through land-burning practices by cajuput oil farmers.

Abstract

This study aimed to assess the population and habitat characteristics of the Rainbow Lorikeet (Trichoglossus haematodus) in the Leahari Village Forest, Ambon Island. This study was conducted to provide a comprehensive understanding of population density, spatial distribution, and habitat characteristics that support the existence of this species. Direct field observations were conducted using line transect and point count methods, complemented by vegetation analyses to identify food tree species, canopy structure, and other environmental factors influencing the occurence of the Rainbow Lorikeet. The results showed that the Rainbow Lorikeet population in the Leahari Village Forest remains relatively stable, with higher average density observed in primary forest areas compared to secondary forest. The species distribution was concentrated in areas with abundant food trees such as Ficus, Syzygium, and Erythrina, as well as in habitats characterized by dense canopy cover and moderate elevations between 50–200 meters above sea level. Anthropogenic disturbance including land clearing and hunting, were found to negatively affect population numbers, particularly in the forest edge areas. These findings suggest that the persitence of the Rainbow Lorikeet is strongly dependent on the availability of food resources and the sustainability and integrity of its natural habitat. Therefore, conservation strategies should prioritize the protection of key food tree species, the regulation of human activities in and around forest areas, and the enhancement of local community awareness regarding the importance of conserving the Rainbow Lorikeet as part of Maluku's endemic biodiversity.

Abstract

This study aims to assess forest health based on species diversity indicators around the Way Kalam Waterfall tourism area in Penengahan, South Lampung. The Forest Health Monitoring (FHM) method was applied using four cluster plots to evaluate the condition of vegetation through measurements of species diversity, composition, and the structure of tree communities. The results showed that the Shannon-Wiener diversity index (H’) in all clusters was categorized as low, indicating a homogeneous vegetation structure and dominance of several species. Despite the low diversity values, the final forest health scores (NKH) revealed that three clusters were classified as “Good,” while one cluster fell into the “Poor” category due to higher ecological pressure and reduced species variation. These findings demonstrate that although the forest ecosystem is still functioning, it is experiencing biodiversity decline, which may affect long-term ecological stability. Therefore, biodiversity indicators remain essential for detecting early ecological disturbances, particularly in tourism areas that are vulnerable to human activities. The study concludes that effective management strategies, including vegetation enrichment, controlled tourism activities, and regular forest health monitoring, are necessary to maintain ecological resilience and support sustainable forest conservation.

Abstract

The research was conducted in July 2025 using an inventory method by establishing observation transects measuring 100 m in length and 20 m in width. Pest sampling was carried out using several techniques, including hand collecting, pitfall traps, sweep nets, and bait traps. Data analysis was performed by calculating the intensity of pest attacks and the percentage of infestation area on observed plants. The results showed that three main pest species attacked candlenut plants: termites (Cryptotermes sp.), ambrosia beetles (Xylosandrus crassiusculus), and wood grasshoppers (Valanga nigricornis). The highest damage intensity was caused by wood grasshoppers at 26.12%, categorized as moderate damage, while ambrosia beetles caused 4.36% damage and termites 1.10%, both categorized as minor damage. The percentage of infestation area across five observation plots ranged from 50.00% to 69.57%, classified as moderate to severe infestation. The high level of pest infestation was influenced by environmental factors such as temperature, humidity, food availability, and habitat conditions that support insect population development. In conclusion, pest attacks on candlenut plants in Wail Matai Hamlet are relatively high, particularly caused by wood grasshoppers that damage the leaves. Therefore, integrated pest management and regular monitoring are necessary to prevent further damage to candlenut plants in the area.

Abstract

Indonesia’s dependence on wheat imports as a raw material for wheat flour continues to increase, whereas the use of breadfruit flour (Artocarpus altilis) as an alternative remains limited. This study, titled Application of Breadfruit Flour (Artocarpus altilis) as a Substitute for Wheat Flour in Cookie Production, aims to evaluate the chemical characteristics of breadfruit flour from Maluku and assess the chemical and sensory characteristics of cookies formulated with wheat flour and breadfruit flour. The research methods include proximate analysis of breadfruit flour sourced from three different locations (Latuhalat, Arui Bab, and Lat Dalam) and cookie formulations with 0%, 20%, 40%, and 60% breadfruit flour substitution. Moisture, carbohydrate, protein, fat, and ash content, along with sensory evaluation using the hedonic method, by 30 panelists. Breadfruit flour has a high carbohydrate content (77.16% - 84.51%) but a lower protein content compared to wheat flour. The cookie formulation with 40% breadfruit flour substitution exhibited the best chemical characteristics, with moisture, protein, carbohydrate, and ash contents ranging from 2.8% to 3.16%, 6.81% to 7.03%, 18.44% to 18.61%, 70.01% to 70.36%, and 1.37% to 1.75%. The sensory evaluation results revealed that the panelists preferred cookies made with breadfruit flour from Latuhalat, with the highest scores in aroma (3.515), texture (3.284), color (3.58), and taste (3.25). Breadfruit flour can be used as a substitute for wheat flour to produce cookies with favorable chemical and sensory characteristics, particularly in a formulation comprising 60% wheat flour and 40% breadfruit flour. Furthermore, breadfruit flour holds potential as a local food source to enhance food security. Keywords: chemical characteristics; cookie formulation; sensory evaluation; wheat flour subtitution
