Abstract

Oriented strand board (OSB) merupakan produk papan komposit struktural yang dapat dibuat dari bahan berlignoselulosa seperti kayu dan bambu. Penelitian ini bertujuan untuk mengevaluasi hubungan antara pengujian non-destruktif metode kecepatan gelombang bunyi (stress wave velocity, SWV) dan pengujian destruktif ((modulus of elasticity, MOE) dan modulus of rupture, MOR)) OSB yang terbuat dari strand bambu andong (Gigantochloa verticillata Munro). Strand bambu diberi perlakuan steam dengan cara memasukkan strand bambu ke dalam autoklaf pada suhu 126°C dan tekanan 1,4 kg/cm2 selama 1 jam. Perekat yang digunakan adalah fenol formaldehida (PF) dengan kadar 8% dan penambahan parafin sebanyak 1% berdasarkan berat kering oven strand bambu. OSB dibuat tiga lapisan yaitu lapisan inti tegak lurus strand bambu terhadap lapisan muka pada berbagai rasio lapisan muka:inti (face:core:face) papan yang berbeda (25:50:25, 27,5:45:27,5, 30:40:30, 32,5:35:32,5, 35:30:35, dan 37,5:25:37,5). Nilai SWV dihitung menggunakan waktu rambatan gelombang dan digunakan untuk mengukur nilai modulus elastis dinamis (MOEd). Hasil penelitian menunjukkan bahwa semakin tinggi komposisi lapisan permukaan (face) pada arah sejajar panjang strand bambu dapat meningkatkan sifat mekanis papan OSB. Komposisi rasio lapisan face-core mempengaruhi sifat mekanis papan (MOE, MOR, SWV, dan MOEd). Terdapat hubungan yang baik antara pengujian non-destruktif berbasis gelombang bunyi dengan pengujian destruktif yang menggunakan model regresi linear.

Abstract

Infrastruktur kelautan seperti fasilitas dan kapal sangat penting di Indonesia karena posisinya sebagai negara maritim. Kayu untuk tujuan infrastruktur kelautan ini umumnya bersumber dari hutan alam, sehingga perlu ada alternatif dari hutan tanaman untuk pemenuhan kebutuhan kayunya. Kayu nangka dari hutan rakyat dipilih sebagai objek penelitian ini karena adalah jenis kayu yang digunakan dalam penelitian ini. Kayak ini dipilih karena memiliki keawetan yang baik. Tujuan dari penelitian ini adalah untuk mengidentifikasi serangan marine borer terhadap kayu nangka pada berbagai kedalaman laut dan menentukan sifat fisis mekanis kayu setelah direndam di laut. Penelitian dilakukan di Pulau Rambut, dengan contoh uji 24 buah berukuran 30 cm x 5 cm x 2,5 cm. Semua contoh uji disusun dengan tali tambang dan direndam di laut selama tiga bulan pada kedalaman 5 cm di atas permukaan laut, serta 10 cm dan 42 cm di bawah permukaan laut. Hasilnya menunjukkan bahwa contoh uji yang disusun pada kedalaman 5 cm di atas permukaan laut sangat tahan terhadap marine borer, dan contoh uji yang disusun pada kedalaman 10 cm dan 42 cm di bawah permukaan laut tahan terhadap marine borer. Nilai MOE untuk kontrol adalah 79994 kg/cm2 dan turun menjadi 48714 kg/cm2 setelah direndam di laut; MOR adalah 1329 kg/cm2 untuk kontrol dan turun menjadi 672 kg/cm2 setelah direndam di laut. Berat kayu kontrol adalah 0,55, tetapi beratnya sedikit turun menjadi 0,51 setelah direndam di laut. Nilai mekanis MOE dan MOR antara contoh uji kontrol dan setelah direndam berbeda nyata. Namun, kedalaman perendaman contoh uji tidak berpengaruh nyata terhadap nilai mekanisnya.

Abstract

This study examined the intensification of the Urban Heat Island (UHI) phenomenon in Bogor City, Indonesia, over a ten-year period from 2013 to 2023. Rapid urbanization has led to extensive changes in land cover, primarily the conversion of vegetated areas into built-up zones. This research integrated remote sensing analysis using Landsat 8 OLI/TIRS imagery with field-based measurements of the Temperature Humidity Index (THI) to assess spatial patterns of Land Surface Temperature (LST), vegetation cover (NDVI), and built-up area expansion (NDBI). The results indicated a notable increase in UHI intensity, as reflected in the expansion of high LST zones (29-32 °C) and a reduction in cooler zones (23-26 °C). Built-up areas increased most significantly in Tanah Sareal (11.98%) and West Bogor (8.49%), while vegetation cover declined sharply, especially in North and Central Bogor. Regression analysis showed a strong negative correlation between NDVI and LST (R² = 0.59) and a positive correlation between NDBI and LST (R² = 0.60), confirming the thermal buffering role of vegetation and the heat-amplifying effect of built surfaces. THI measurements indicate widespread thermal discomfort (THI >27 °C) in densely populated urban areas. However, Central Bogor maintains lower LST and THI values, indicating better thermal comfort. These findings highlight the crucial role of urban green infrastructure in mitigating urban heat island (UHI) effects, underscoring the importance of adopting nature-based solutions, such as expanding green spaces and implementing sustainable land management practices, to enhance urban climate resilience.

Abstract

Urban forests are critical green infrastructures that provide multiple landscape services, including carbon sequestration, microclimate regulation, and biodiversity support, thereby contibuting to global climate adaption and urban sustainability. This study aimed to analyze the Patriot Bina Bangsa (PBB) Urban Forest’s role in providing comfort through carbon storage and sequestration using the i-Tree Eco model, microclimate monitoring, and evaluating its contribution to landscape services. Data were collected from 12 sample plots using a stand inventory that refers to the i-Tree Eco data collection protocol. An estimated 750 trees, dominated by Nauclea orientalis and Swietenia macrophylla, with a moderate species diversity index (H' = 1.7). The urban forest stored 241 tons of carbon and sequestered 17.85 tons annually, valued at approximately 151 million rupiah. Temperature Humidity Index (THI) values indicate moderate thermal comfort, especially during peak hours. A multifunctional landscape service assessment shows high for regulation functions and landscape disservices, and medium for habitat, information, and production. These findings highlight the importance of urban forests and tree diversity in maintaining landscape services. The indicators outlined in this study provide a basic method for assessing the services provided by urban forest landscapes. It can be used as a tool to improve the management of urban forest systems and monitor the impact of urban greening policies on human well-being in urban landscapes

Abstract

The Royal Palm (Roystonea regia) is a type of monocotyledonous plant that is widely planted, especially as an ornamental plant that is part of the urban landscape. However, in its growth, there is a natural cycle where the royal palm leaves will fall and end up as waste. In this case, the royal palm leaf sheath is thought to have potential as a composite reinforcement material. However, in its utilization as a composite reinforcement material, basic information such as the physical and mechanical characteristics of the material needs to be known. The purpose of this study was to evaluate the physical and mechanical properties and potential utilization of the royal palm leaf sheath. The research shows that the green royal palm leaf sheath's water content and density are higher than the brown leaf sheath. In addition, the dimensional stability of the green leaf sheath is higher than that of the brown leaf sheath. The tensile strength of the green conditions is lower than that of the brown conditions, and the strength decreases towards the core of the royal palm leaf sheath. Meanwhile, the tensile strength of the fibers from the two leaf sheath conditions is not significantly different. This test shows that the royal palm leaf sheath fiber is classified into fiber class II. This shows that the royal palm leaf sheath has the potential as a composite reinforcement material.

Abstract

Fungus comb is a structure made by termite colony Macrotermitinae with lots of potential because it contains secondary metabolites such as steroids, terpenoids, and saponins and compounds containing antioxidant and anti-tyrosinase properties. This study aimed to determine fungus comb extracts' fingerprint pattern, antioxidant capacity, and anti-tyrosinase activity. Thin layer chromatography (TLC) was used to determine fingerprint patterns. The resulting TLC pattern was processed with ImageJ and converted into a densitogram. The fungus comb was extracted with n-hexane and ethyl acetate. TLC results showed that fungus comb extracts contain steroids and terpenoids and have antioxidant properties. The antioxidant capacity assay was carried out with 2,2-diphenyl-1-picrylhydrazyl reagent. N-hexane extract had an antioxidant capacity value of 9.07 mg ascorbic acid equivalent (AAE)/g extract, while ethyl acetate extract had 6.04 mg AAE/g extract. Anti-tyrosinase activity assay was carried out with L-tyrosine and L-3,4-dihydroxyphenylalanine (L-DOPA) as substrates. N-hexane extract had a better anti-tyrosinase activity with IC50 of 1804 µg/mL for L-tyrosine and 6784 µg/mL for L-DOPA.

Abstract

A designer needs to simplify the bamboo cross-section shape variation to the closest standard geometry so a structural analysisof bamboo construction can be carried out. Bamboo culm’s cross-sectional geometrics vary and may be similar to conic such as acircle, ellipse, or egg-shape ring. The best-fit conic section, which is the most similar to the actual geometric shape of the bambooculm’s cross-section, should be considered. This study formulates mathematical equations for calculating the bamboo culm’s crosssectional properties (including the area, the first moment of area, the centroid, and the moment of inertia), which are fitted by acircle, ellipse, and egg-shaped ring. The thickness, diameter, major axis, and minor axis of four bamboo species (i.e., Gigantochloaapus, Bambusa vulgaris, Gigantochloa pseudoarundinacea, and Gigantochloa robusta) were measured, and thosevalues were substituted into the equations to produce the range of cross-sectional properties of each species.

Abstract

Heat treatment is one method that can improve the quality of wood including for fast-growing wood species. However,this treatment can cause some drying defects as well as the change of machining properties after applying that heattreatment. The purpose of this study was to evaluate the effect of wood species and heating time on the drying andmachining defects. The fast-growing wood species used were teak, mangium, jabon, and sengon. The heat treatmentwas carried out at a temperature of 165°C with variation in time were 0 (control), 2, and 6 hours. The result showedthat the moisture content and wood density decreased after heat treatment. Heat treatment was succeeded to decrease themoisture content of 57% and caused a decreasing of density until 20% compared with control wood. The drying defectsof end checks in teak, mangium, jabon and sengon increased after 2 and 6-hour heat treatment. In the other hand, thesurface checks defect of teak, mangium, sengon and jabon were decreased. The defects after applying machining activitiesi.e. the defects of sanding, planing, shaping, and boring were decreased in teak, mangium, jabon and sengon after heattreatment of 2 and 6-hour. Jati was the best wood species in term of machining quality followed by jabon, mangium,and sengon after heat treatment. At the temperature of 165°C in 2 hours could be considered as the appropriate timefor heat treatment in term of obtaining minimal defects of drying and machining.
