“…In general, the maximum CO2 fixation occurs at midday, as well as the optimum temperature for photosynthesis which is equivalent to the air temperature during the day in its natural habitat. Temperature and relative humidity under the tree are related to the high density and area of the tree canopy [44]. This can be seen from the temperature, humidity and light intensity under the teak was lower than without shade.…”

Private forest farmers in Semin Village, Semin District, Gunung Kidul Regency transformed the cropping patterns from monoculture to polyculture to meet increasing needs. The farmers planted a variety of food crops to fulfill their short and medium-term needs, and woody plants to meet the long-term needs. Beside this, farmers have processed arrowroot tubers into flour, which can increase household income. The tuber plants apart from being able to live under the shade, have a low glycemic index value so they can be consumed by the diabetics. The method used randomized block design, trials were conducted by cultivating 3 species of tuber plants under the teak shade. Species of tuber plants were arrowroot, canna and yam. The treatments given were: 1) without shade, 2) under 5-year-old teak, 3) under 7-year-old teak. The aim was to understand the relationship between tuber plant growth variables and their environments. Tuber plant growth variables were height and diameter of plant, number of leaves and number of shoot. Environment variables were height and diameter of the teak trees, soil characteristic, and micro climate condition. The relationship was analyzed using linear regression. The results of regression analysis showed that there was a relationship between soil characteristics and plant height (R2=100%), stand height and number of leaves (R2=25.50%), air temperature and number of shoots (R2=22.60%), humidity and the number of shoots (R2=16.70%), light intensity and the number of shoots (R2=14.80%), as well as temperature, humidity, light intensity, percent canopy cover simultaneously and tuber weight/clump (R2=39.10%).

“…The increasing temperature in urban areas globally, especially in Padang City is caused by several factors such as greenhouse gas effect, excessive carbon gas usage and fuel consumption from fossil (Astra, 2010;Supriatin & Martono, 2016;Wallington, Srinivasan, Nielsen, & Highwood, 2009). The increasing of temperatures can affect human comfort and productivity (Endes N. Dahlan, 2014).…”

“…In addition, the trees in the middle of the city can reduce the surrounding temperature by 3.46% during the early days of the rainy season (Irwan, 1994). While the trees that make up the city forest can reduce the daily temperature by 30.2 0 C with air humidity of 74% (Endes N. Dahlan, 2014). In reality, however, there was a negative linear pattern of carbon presence in Padang City from 1988, 1998, and 2008.…”

The decreasing of environmental quality in padang is caused by the changes of the land, the increasing number of vehicles and the increasing number of population. The solution to overcome these problems is by providing a green open space at universitas negeri padang (unp). The objectives of this study are 1) to analyze the needs of green open space at unp, 2) to plan the construction of open green space at unp. The method employed in this study was survey by using spatial analysis remote sensing data from google earth. The results of the study revealed that unp had open green space as large as 7.643 ha. The area of green open space at unp that fulfilled the width criteria was as much as 10%, and the fulfillment of population and clean air criteria was as much as 20%. However, the minimum width criterion of green open space, which was as much as 30%, was not fulfilled yet. The discrepancy between the area of open green space and the criteria of minimum width (30%) was 0.447 ha. Such lack of green open space can be filled by: optimizing the unoccupied land as large as 1.4 ha by planting the clump, providing 2308 flower’s pots, and making use of building shelter and building lobbies, and campus corridor to be planted with clump, ornamental plants or other types of epiphytes and lianas.

Breadfruit is one type of versatile plant that is of economic value because itproduces fruit with a fairly high nutritional content. Breadfruit plants havediverse morphological variations, so their morphological variations can be usedas a way to determine a type of breadfruit, especially whether the quality issuperior or not. This study aims to determine the morphological variations ofbreadfruit plants (Artocarpus altilis (Parkinson) Forsberg) originating fromvillages in Bekasi City. The stages of this study include observation andobservation of morphological characters ranging from trees, leaves, flowers andfruits. Breadfruit plants in Bekasi city have an average height of ±11.5 m, withthe highest breadfruit plants reaching 12.90 m and the lowest 7.9 m, the largestbreadfruit stem circumference is 125 cm and the smallest is 98.5 cm, thelargest breadfruit canopy diameter is 4.67 m and the smallest is 6.14 m, theshape of the canopy of the Breadfruit plant in Bekasi city is irregular, pyramidsand pyramids are broad, the leaves of the Breadfruit plant in Bekasi city, ingeneral, have the same shape, namely dark green, rhombus-shaped withpinnate leaf bones, tapered leaf tips and leaf edges are enamelled, the maleflowers of Breadfruit are in the form of a whole with a diameter of up to 5 cmand a length of 45 cm consisting of many individual flowers, tubular flowerscontaining a single stamen with two anthers on thick filaments, male and femaleflowers on breadfruit plants are separated in the same plant, the morphology ofbreadfruit in the city of Bekasi has the characteristics of a rounded shape, thesurface of the skin of the fruit is prickly, if palpable it feels rough, as well aswhite fruit flesh.
