Phenology is a study that explores periodic tree lifecycle events and how those events are influenced by seasonal climatic variation. This study aimed to observe the leaf-shedding period of three commonly found deciduous tree species in the tropics: Ficus glauca, Terminalia catappa, and Cassia fistula; and to analyze the climatic driving factors to trees' phenological phases. A field survey was conducted to observe the samples, each species consisted of five trees. The survey was conducted weekly from September 2016 to February 2017 in Bogor City and Regency. It was found that F. glauca shed its leaves more than once a year. The canopy coverage reached its lowest in February (65.7% coverage). Leaf shedding process in T. catappa reached its peak in January (83.7% coverage), meanwhile, C. fistula's shedding period is suspected to happen before September because its canopy coverage kept increasing during the survey (69.7%–95.1% coverage). The climatic factor that significantly affected F. glauca was the previous month's rainfall. When the rainfall in the previous month decreases, the leaf shedding increases. T. catappa and C. fistula were significantly affected by day length. For T. catappa, when day length decreases, the leaf shedding increases. Meanwhile, for C. fistula, when day length increases, it is shedding its leaves. Leaf phenology of deciduous trees in a tropical climate was affected by different climatic factors depending on their species.

Along with the enormous impact on computational development in architecture and urban design, the way in approaching the built environment is shifting and intended to look closer to performance and evidence-based design. This development holds promise in handling complex computation to approach desired targeted design goals. However, the implementation of form-finding and design performance optimization still lacks, particularly in Japan's sub-tropical climate. This paper describes the parametric design and design exploration process's implementation through the generative algorithm platform to develop a benchmark model to predict building energy and daylight performance and find possible design solutions from the iteration process during the early phase of the design process. The variables incorporated related to the glazing ratio, the length of the overhang, and building orientation. Grasshopper, a parametric-based plugin that works in Rhinoceros, is used to arrange a parametric definition for the overall experiment. The tools used to investigate the environmental analysis and energy consumption are Ladybug and Honeybee, and the exploration process will be conducted using Design Explorer. The context will be situated in Orio district and uses the EPW file of Kitakyushu city, Fukuoka, Japan. The results of this research furthermore can potentially be a comparison for more dynamic factors.

Nutmeg tree (Myristica fragrans) is Indonesian native tree species originating from Maluku Island, especially Ambon and Banda. The spread of nutmeg in Bogor area can be traced back to the Dutch colonial period when different kinds of spices were traded across the Indonesian archipelago and beyond. Having this long history, nutmeg is now widely used in Bogor's culinary. At the national level, it has high economic value and become one of Indonesia's main export products. However, there is little research on nutmeg tree spatial distribution. The objectives of the study were : (1) identify the nutmeg trees spatial distribution in Bogor city (2) mapping the existence and identification of nutmeg trees conditions and growing environment. This research was conducted Bogor City from February - May 2018. The data was obtained through direct interview, study field, and study literature. Data collection is determined based on the distribution of nutmeg trees in Bogor City, and extinct status based on study literature. Furtehermore, the existence of nutmeg trees in Bogor collected used purposive and snowball technique. The results showed that a total of 108 nutmeg trees were found in all sub-districts of Bogor city. These trees grow in a variety of areas such as green corridor, public park, agriculture farm, riverbanks, yard, office park, and cemetery. The results of this study can be used as the basis for determining the preservation strategy and area for nutmeg conservation in Bogor city.
In this paper, numerical simulation is conducted when total 5.3 million units of SOFC and PEFC are operated nationwide, for power generation configuration and electricity supply amount of general electric utilities be...

There have been many experiments regarding reusing plastic bottles, especially polyethylene (PET) as building materials. Some of them are experimenting with their compressive strength as exterior wall bricks (Mansour, et al., 2015); their energy consumption as roof insulations (Racolta, et al., 2016); their compressive and flexural strength as interior walls (Santana, 2016); and their compressive strength as walls and slabs (Oyinlola, et al., 2018). This paper discusses the compressive strength and the flexural strength of PET bottles as structural floor panels. This study explored the positions, binders, patterns, fillers, sizes, and supports of the PET bottles panel to reach the optimum combination of compressive and flexural strength. The experimental result shows that PET bottles panel with an upright position, sealant binder, and sand filler has better compressive strength and flexural strength. It also shows that the panels with more bottles face downwards have better compressive strength, while the ones with more bottles face upwards have better flexural strength. On the other hand, panel with smaller size and higher amount of support shows better flexural strength.

Argapura is one of the village areas in Cigudeg Subdistrict which has potential unique characteristics for a tourist destination, namely Geopark. Argapura Village is one of the Pongkor National Geopark development villages covering 15 sub-districts in Bogor Regency. Pongkor National Geopark is a unitary space with geodiversity, culturediversity and biodiversity which aims to preserve and protect the wealth of natural resources. The geopark is located very close to tourism activities, but the existing tour has not specifically touched the educational aspect (educational tourism). Educational tourism is a tourism packaging program that is loaded with educational values in each of its activities. Argapura Village needs to be developed educational tourism aimed at all visitors. The objectives of this study were to identify and analyze the potential of educational tourism objects in Argapura Village, and to arrange educational tourism program in Argapura Village. Data collection through literature studies, field surveys and interviews with stakeholders. Data analysis using tables and described based on the criteria of educational values and geopark elements. The results of study showed that Argapura Village has two main potential attractions/educational tourism objects, namely Angklung Gubrag and Gudawang Caves. Angklung Gubrag is an educational tourism attraction that has high cultural, historical and religious values. Gudawang Cave is an educational tourism object in the form of karst ecosystem. In addition to the both of tourism objects, there are several other potential tourism objects and characteristics of the Geopark. The Argapura Village educational tourism was compiled includes two main programs, namely the half-day and the full-day visiting programs.

Economic growth promoted by large investment projects in the city of Seropédica and surrounding areas is not accompanied by a territorial planning that supports future growth scenarios. The challenge of the municipality is to prepare to have its territory fully transformed. This study aimed to establish quantitative data on the interferences that the growth model practiced has caused in its main watercourse called Val?o dos Bois. For this, its morphometric characteristics and physicochemical parameters of water quality were measured, and computational simulations of the self-purification processes were performed at various points, as well as the infiltration and precipitation processes, surface flow and leaching in four occupation scenarios of the urbanized areas of the basin, for rains with five different return periods.
