Abstract

Composite materials have become highly important in the manufacturing industry. However, the development of composites often faces the challenge of finding effective, economical, and environmentally friendly reinforcing materials. This study aims to analyze the comparison of physical characteristics in composite materials reinforced with natural fibers through Vickers hardness testing and then compare these hardness values with composite materials reinforced with synthetic fibers. The Vickers hardness testing method adheres to the ASTM E348 microhardness testing standard. The results show that the addition of fibers to composite materials tends to increase the likelihood of voids or trapped air bubbles within the composite material, which increases its porosity value. Furthermore, the use of synthetic fibers, especially carbon fiber, is still superior to pineapple leaf fiber (PALF) because the hardness value of carbon fiber is indeed superior to other fibers. However, pineapple leaf fiber (PALF) has advantages in its stability, is more environmentally friendly, and has a lower production cost compared to synthetic fibers.

Abstract

The cultivation of Alabio ducks (Anas Platyrynchos Borneo) so far is still natural and only involves one parameter; furthermore, each location has different characteristics. The hierarchical structure constructed has a ranking of importance as an alternative option for ducks' development in peatland ecosystems. This research aims to formulate a strategy for duck production in the Hulu Sungai Utara Regency. AHP (Analytical Hierarchy Process) method in this study is used to structure the decision-making flow from goals and alternatives and weigh the variables. Data collection was carried out with duck farming experts from academia, farmer groups, and policymakers. This study found that the availability of feed, both sago (0.254) and bran (0.218), is a significant component from an ecological perspective. Distance to market (0.307) and hatchery location (0.287) is an economic variable. The social part consists of distance from the settlement (0.443) and labor availability (0.247). Meanwhile, the availability of feed (0.282), hatchery technology (0.269), and Mina ducks (0.251) are the development strategies for duck cultivation in swamp areas, and economic stimulus (0.93) is the final contributor.

Abstract

One of the uses of used oil is as fuel for multifuel stoves. A multifuel stove is a stove that has flexibility in its fuel selection. In the operation of a multifuel stove, the air supply plays an important role in the combustion process. This study discusses the influence of air velocity on fire characteristics and water temperature during the heating process. In this study, three variations of air velocity were used, namely 13 m/s, 12 m/s, and 11 m/s. Based on the tests that have been carried out, it was found that the speed of air blown into the combustion chamber can affect the temperature and duration of the flame. The faster the speed of air that is blown into the combustion chamber, the higher the temperature of the flame will be, but the faster the fire will be extinguished. This is because more oxygen is supplied into the combustion chamber, causing the combustion process to take place more quickly and intensely. Meanwhile, regarding the water heating time, the time required by the three variations of air speed to heat 0.5 kg of water to boiling is 1.5–2 minutes, which surpasses the performance of gas stoves and conventional electric stoves.

Abstract

Land cover change on Sumatra Island has accelerated rapidly over recent decades, marked by extensive tropical forest deforestation, widespread peatland degradation, and increasing disaster occurrences. Spatio-temporal analysis using multi-temporal satellite data provides valuable insights into the trajectories of vegetation cover change in this region. This study synthesizes findings on patterns of forest conversion to other land uses (plantations, agriculture, and infrastructure), as well as vegetation recovery patterns following fire events, particularly in peatland areas. The results reveal several dominant change trajectories: (1) deforestation followed by conversion to agricultural and plantation land, (2) cyclical changes in plantation forests, including planting, harvesting, and replanting phases, and (3) natural secondary regeneration on abandoned land after deforestation. Furthermore, in cases where deforestation is driven by land and forest fires, fire frequency plays a significant role in shaping vegetation succession pathways. Areas burned only once are able to recover toward near-original conditions after several years, whereas areas subjected to repeated fires exhibit slower recovery and tend to be dominated by shrub vegetation. These findings highlight the importance of sustainable landscape management informed by spatio-temporal data, including controlling deforestation and restoring peatlands through rewetting and vegetation rehabilitation, to prevent further degradation and support long-term ecosystem recovery.

Abstract

Tropical peatlands are among the most fire-prone ecosystems in Southeast Asia, where recurrent burning causes long-term degradation, carbon loss, and biodiversity decline. Assessing spatio-temporal patterns of recovery is therefore essential for guiding effective peatland restoration and fire prevention strategies. This study investigated vegetation recovery dynamics in a fire-affected peatland in Sumatra, Indonesia. Multi-temporal satellite imagery was processed to extract the Enhanced Vegetation Index (EVI) and Normalized Burn Ratio (NBR). Fire frequency and severity were further analyzed through hotspot distributions and fire history. The results revealed that NBR and dNBR were highly effective in detecting burned areas and assessing severity, while EVI provided complementary perspectives on recovery trajectories. Vegetation in once-burned areas showed relatively steady regrowth, with EVI values approaching pre-fire levels after several years. In contrast, repeatedly burned areas exhibited slower and more heterogeneous recovery, with fluctuating EVI pattern reflecting vegetation growth succession. Field vegetation surveys confirmed that repeated fires drastically simplified forest structure, reducing tree and pole density and favoring shrubs and ferns such as Stenochlaena palustris and Melastoma malabathricum. Overall, the study demonstrates that fire frequency and severity are critical determinants of peatland recovery. The EVI offers valuable insights into vegetation dynamics, while NBR provides reliable fire history mapping. These findings underscore the importance of combining spectral indicators with ground-based vegetation data for long-term monitoring and highlight the need for targeted restoration strategies, including hydrological rewetting and assisted natural regeneration, in repeatedly burned peatlands.

Abstract

The Covid-19 pandemic has had a global impact on all sectors including the environment. The spread of Covid-19 is very much influenced by human activity and mobility. Human activities are also closely related to air pollutant emissions. High concentrations of air pollutants during the Covid19 pandemic will increase the risk of being exposed to Covid-19. Jakarta and its surrounding area (known locally as Jabodetabek) have high population density. These cities are economic and industrial centers. Air pollutant emissions in these cities are very high. High concentrations of air pollutants during the Covid-19 pandemic will increase the risk of being exposed to Covid. To anticipate this problem, the government made a Large-Scale Social Restriction Policy (PSBB). Limited human activities, in addition to having an impact on reducing the risk of humans being exposed to Covid-19 from the droplets released by tested-positive of Covid-19, also have an impact on reducing emissions of air pollutants so that they can reduce the risk of being exposed to Covid-19. Several variables that influence vulnerability and risk to exposure to Covid-19 are the distribution of settlements, roads, economic centers (markets, business centers, industrial centers), and human mobility. In this study, we will also analyze the role of green open space on the risk of exposure to Covid-19. Green open space plays an important role in reducing air pollutants so that it will also affect the risk of being exposed to Covid-19. This study aimed to 1) examine the distribution of air pollutants based on the vulnerability and risk of COVID-19 in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Jabodetabek), and 2) examine the results of the overlay between land cover and vulnerability and risk to Covid-19.

Abstract

Kegiatan pertambangan terbuka Bijih Bauksit yang dilakukan pada Areal yang Luas dan tersebar meningkatkan potensi pencemaran kualitas air sehingga diperlukan pengelolaan dengan baik. Salah satu pemodelan spasial GIS yang dapat memprediksi erosi adalah model Geospatial of water Erosion Prediction Project (GeoWEPP). GeoWEPP dapat memprediksi besaran erosi dan memetakan prediksi lokasi terjadinya sedimentasi di lokasi kegiatan penambangan bijih Bauksit serta membuat rencana pengelolaan dan biaya untuk pengendalian erosi, diantarnya dengan membuat settling pond. Pembangunan basis data GeoWEPP diantaranya melakukan Pembuatan peta penggunaan lahan, Peta topografi, Peta tanah dan analisis data curah hujan dan suhu. Hasil analisis terhadap 30 bukit dengan total luas 13 602.48 Ha didapatkan Sedimen sebesar 150 186 m3/bulan dan jumlah aliran air permukaan (run off) sebesar 4 202 267 m3/bulan. Berdasarkan analisis GeoWEPP pada rencana areal blok tambang didapatkan 30 titik outlate yang akan dijadikan lokasi pembangunan settling pond. Biaya yang diperlukan untuk pembangunan seluruh settling pond adalah sebesar Rp. 222 047 640 944 untuk biaya optimis dan Rp. 222 773 049 768 untuk biaya pesimis. Biaya perawatan settling pond pada seluruh titik outlate selama operasional adalah sebesar Rp. 3 145 414 818. Penamanan cover crops pada areal bekas tambang sangat efektif mengurangi erosi, Sehingga setelah kegiatan tambang telah selesai dilakukan, sebaiknya segera dilakukan penataan lahan dan penanaman cover crops.

Abstract

Basically, coastline changes include accretion (raised soil) and abrasion. This study aims to analyze coastline changes in the Indramayu Regency between 1989 and 2019, as well as the causing factors. The secondary data were obtained from Landsat 5 Satellite Imagery in 1989, 1999, 2009, and Landsat 8 in 2019. This analysis used BILKO method, which is a Landsat image analysis to separate land and sea areas. Then overlay method, which was used to delineate boundary. Spatial analysis showed coastline changes in the Indramayu regency of both accretion and abrasion. In the 1989-1999 period, there was an accretion of 319 ha, while there was an abrasion 1291 ha. Furthermore, in the 1999-2009 period, there was an accretion of 349 ha, and abrasion of 1125 ha. Also, in the 2009-2019 period, there was an accretion of 698 ha, and abrasion of 358 ha. Meanwhile, the factors that cause coastline changes are natural such as wind, waves, currents, as well as human factors such as the conversion of mangrove land to ponds and also planting activities. Therefore, efforts made by the government are making waves containment tool and planting mangrove vegetation.

Abstract

Ekosistem mangrove merupakan kawasan yang sangat potensial, umumnya berada di kawasan ekoton (kombinasi kawasan intertidal dan supratidal), dimana terdapat interaksi antara perairan (laut, air payau, dan sungai) dengan kawasan daratan. Indonesia khususnya wilayah Banten dan Jawa Barat memiliki kawasan mangrove yang sangat luas dan saat ini terancam alih fungsi lahan. Apalagi pemetaan sebaran hutan bakau menggunakan platform Google Earth Engine berbasis Cloud Computing kurang dipublikasikan. Oleh karena itu, penelitian ini dilakukan dengan memperkenalkan sebaran hutan mangrove yang melibatkan metode algoritma klasifikasi Random Forest (RF), dan mencari modifikasi indeks yang terbaik. Uji kombinasi dilakukan dengan melibatkan indeks NDVI, EVI, ARVI, SLAVI, IRECI, RVI, DVI, SAVI, IBI, GNDVI, NDWI, MNDWI, dan LSWI. Sebaran mangrove terdapat di tiga provinsi (Jawa Barat, Banten, dan DKI Jakarta) yaitu seluas 933,54 ha (8,372%), 1.537,89 ha (18,231%), dan 8.184,82 ha (73,397%). Dari 70 pengujian kombinasi, indeks LSWI (K13, Type-A) merupakan kombinasi dengan tingkat akurasi terendah sebesar 58,45% (Overal Accuracy) dan 39,59 (Kappa statistik), dan kombinasi K23 (SAVI-MNDWI-IBI) merupakan kombinasi yang terbaik yaitu 96,48% dan 92,79. Hasil dan rekomendasi dalam penelitian ini diharapkan dapat digunakan sebagai acuan dalam menentukan kebijakan perlindungan kawasan mangrove dan referensi untuk penelitian selanjutnya.
