In 2050, several areas in Jakarta are predicted to sink, especially in the Northern, that have experienced significant subsidence in the ground level. One of the inhabited areas that need to be considered in the future is Kampung Kota in a coastal area. Most of the Kampung Kota currently have a high building density and minimal green space. Here, the place to face the overflowing water from the sea, Kampung Marlina. Marlina is an extension of the residential area for people working in the Sunda Kelapa and Kota Tua areas (1980). In the past, the residents' houses were the Stilt Houses, residents can preserve fish under the house and it became the habit of the residents there, then it dissapear by time. Stilt Architecture is designed to accommodate the activities of the citizens of Jakarta in facing the phenomenon of the Jakarta Sinking in 2050 with the issue of tidal flooding from the sea. Using permaculture design theory, the site pattern was studied and then placed the waterways to adjust to the drainage in Kampung Marlina. Then using the Urbanism Landscape Method, Program Method and raising the habits of the residents, the building is designed like a stage by presenting the concept of a pond below, so that it serves to anticipate flooding from the sea, as well as a means for residents to cultivate seagrass beds and small fish and shrimp. In areas equipped with permaculture gardens on the edges of these airways. The garden is planted with plants with high water absorption. In the area there is a research building and lodging for researchers or students.Keywords:  coastal; kampung kota residents; kampung marlina; permaculture; rob floodAbstrakPada tahun 2050, beberapa daerah di Jakarta diprediksi akan tenggelam, khususnya pada bagian Utara. Hal ini ditandai oleh daerah-daerah yang telah mengalami turunnya permukaan tanah secara signifikan. Salah satu kawasan berhuni yang perlu diperhatikan di masa depan adalah Kampung Kota di daerah pesisir. Sebagian besar Kampung Kota saat ini memiliki kepadatan bangunan yang tinggi serta minim ruang hijau. Di sini, tempat yang pertama kali akan menghadapi luapan air dari arah laut, Kampung Marlina. Kampung Marlina merupakan perluasan daerah bermukim untuk masyarakat yang bekerja di daerah Sunda Kelapa dan Kota Tua (1980). Dahulu rumah-rumah warga merupakan Rumah Panggung, yang di bawah rumah tersebut warga dapat memelihara ikan dan menjadi suatu kebiasaan warga di sana, kemudian ditinggalkan seiring berjalannya waktu. Arsitektur Panggung ini dirancang demi tujuan mewadahi aktivitas warga Jakarta dalam menghadapi fenomena Tenggelamnya Jakarta di tahun 2050 dengan isu luapan air/banjir rob dari arah laut. Menggunakan teori desain permakultur, pola tapak distudi dan kemudian menempatkan jalur-jalur air menyesuaikan dengan drainase pada Kampung Marlina. Kemudian menggunakan metode Landscape Urbanism, metode Program dan mengangkat kebiasaan dahulu warga, bangunan dirancang seperti panggung dengan menghadirkan konsep kolam di bawahnya, sehingga selain berfungsi mengantisipasi banjir rob dari laut, juga sebagai sarana warga membudidayakan padang lamun serta ikan kecil dan udang. Pada kawasan dilengkapi dengan kebun permakultur pada tepi jalur-jalur air tersebut. Kebun tersebut ditanami tanaman dengan penyerapan air yang tinggi. Pada kawasan terdapat bangunan riset serta tempat penginapan untuk para periset ataupun pelajar.

The Impact

Bio-based aerogels containing cellulose nanofibrils (CNFs) are promising materials due to the inherent physical properties of CNF. The high affinity of cellulose to plant hemicelluloses (xyloglucan, xylan, pectin) is also an opportunity to develop biomaterials with new properties. Here, we prepared aerogels from gelled dispersions of CNFs and xyloglucan (XG) at different ratios by using a freeze-casting procedure in unidirectional (UD) and non-directional (ND) manners. As showed by rheology analysis, CNF and CNF/XG dispersions behave as true gels. We investigated the impact of the freezing procedure and the gel’s composition on the microstructure and the water absorption properties. The introduction of XG greatly affects the microstructure of the aerogel from lamellar to cellular morphology. Bio-based aerogels showed high water absorption capacity with shape recovery after compression. The relation between morphology and aerogel compositions is discussed.

Abstract. Over the past 10 years (2005–2014), ground-level O3 in Hong Kong has consistently increased in all seasons except winter, despite the yearly reduction of its precursors, i.e. nitrogen oxides (NOx =  NO + NO2), total volatile organic compounds (TVOCs), and carbon monoxide (CO). To explain the contradictory phenomena, an observation-based box model (OBM) coupled with CB05 mechanism was applied in order to understand the influence of both locally produced O3 and regional transport. The simulation of locally produced O3 showed an increasing trend in spring, a decreasing trend in autumn, and no changes in summer and winter. The O3 increase in spring was caused by the net effect of more rapid decrease in NO titration and unchanged TVOC reactivity despite decreased TVOC mixing ratios, while the decreased local O3 formation in autumn was mainly due to the reduction of aromatic VOC mixing ratios and the TVOC reactivity and much slower decrease in NO titration. However, the decreased in situ O3 formation in autumn was overridden by the regional contribution, resulting in elevated O3 observations. Furthermore, the OBM-derived relative incremental reactivity indicated that the O3 formation was VOC-limited in all seasons, and that the long-term O3 formation was more sensitive to VOCs and less to NOx and CO in the past 10 years. In addition, the OBM results found that the contributions of aromatics to O3 formation decreased in all seasons of these years, particularly in autumn, probably due to the effective control of solvent-related sources. In contrast, the contributions of alkenes increased, suggesting a continuing need to reduce traffic emissions. The findings provide updated information on photochemical pollution and its impact in Hong Kong.

Laterite samples from Ede area with particle components of 19.7% clay, 32.8% silt and 47.5% sand was stabilized with combined cement, lime and bitumen and test for Compressive strength, Linear Shrinkage, Permeability and Water Absorption. The stabilizers were mixed with laterite soil in different ratios and percentage. The laterite carried 90% which is constant while the three stabilizers shared the remaining 10% in varying form. After 28 days of curing, laterite stabilizer with 90% of laterite, 8% of cement, 1% lime and 1% bitumen (LCLB1) possessed compressive strength of 2.01N/mm2. It Water Absorption Capacity was 3.05%. LCLB4 stabilizer (90% laterite, 6% cement, 2% lime and 2% bitumen) has the same compressive strength with LCLB1 stabilizer but with a high Water Absorption Capacity of 4.2%. The stabilizer of 90% laterite, 3.33% cement, 3.33% lime and 3.33% of bitumen (LCLB8) has the lowest compressive strength of 0.74N/mm2 and the highest Water Absorption Capacity of 5.39%. The results shows that LCLB1 stabilizer is a better stabilizer for strength and blocks made from laterite stabilized with it stand a good alternative to sand Crete blocks in building constructions. The combination of these stabilizers in order to determine a most economical volume combination for optimum performance is highly possible and economical.

‘Archive’ is a totality of records, layers and memories that are collected. A city is the archive that consists of the conscious selection of these layers and traces of the past and the present, looking towards the future. Metaxourgio is an area in the wider historic urban area of Keramikos in Athens that includes traces of various eras, beginning in the Antiquity and continuing all the way into the 21st century. Its archaeological space ‘Demosion Sema’ is mostly concealed under the ground level, waiting to be revealed. In this proposal, Metaxourgio is redesigned in light of archiving. Significant traces of the Antiquity, other ruins and buildings are studied, selected and incorporated in the new interventions. The area becomes the ‘open archive’ that leads towards its lost identity. The proposal aims not only to intensify the relationship of architecture with archaeology, but also to imbue the area’s identity with meanings that refer to the past, present and future.

Observations in drying out pans showed that small (26-37 cm) sharptooth catfish (Clarias gariepinus) can hide at the bottom of small pools filled with sticky mud whereas larger fish stay afloat at the surface in larger pools with sloppy mud, where they easily become prey or succumb to heat stress. The inability of larger fish to keep down in the sloppy mud of up to 40 cm depth is the result of their large bulk and high density of the mud. This may indicate a survival advantage for smaller fish in the final dry-out phase of pools and is supported by the presence of only small fish remains in the last drying up pools of dry pans. Another adaptation of smaller fish includes the temporary congregation outside the water enabling concealment under dense vegetation as a means to escape adverse environmental conditions, including high water temperatures and avian predation. The advantage small fish have over larger catfish under these extreme conditions may explain why catfish are known to show a wide variation in growth rate under natural and aquaculture conditions.

For the past five semesters, the Water Turbine Competition has added significant excitement and motivation to the historically dreaded Fluid Mechanics course offered in the Department of Civil and Mechanical Engineering at the United States Military Academy. The Water Turbine Competition is an adaptation of the national Hydropower Contest. Teams of two or three students build a water turbine that will lift a weight using only the potential energy stored in a tank of water that is suspended above ground level. The water turbine project has proven to be an exciting and beneficial educational tool.
