“…On the other hand, the excessive light intensity will also cause abnormal growth in tolerant termite species (Herdiana et al 2008). The amount of solar energy received daily by a location depends on the period of direct sun exposure and the land covers (forest, open land, densely-covered land, etc.).…”

Abstract. Ariana, Fannani AR, Nandika D, Haneda NF. 2020. Field test on the palatability of the subterranean termites to pine wood with various treatments. Biodiversitas 21: 5763-5771. One of the keys to successfully determining the subterranean termite species' diversity in an area is using wood samples of their preference. This research aimed to evaluate the palatability of the subterranean termites to pine wood (Pinus merkusii) with boiling, steaming, hot vapor pressure, and oven treatments in the Arboretum of the Faculty of Forestry, IPB University, Bogor, West Java, Indonesia, and to analyze the species and the distribution of the subterranean termites that attacked the samples. The wood samples were 2 cm x 2 cm x 46 cm in size (ASTM D 1758-06). The steaming (100°C), boiling (100°C), and hot vapor pressure (1 bar, 105°C) treatments were carried out for five hours, while the oven treatment (103±2°C) was set up for 48 hours. Wood samples without treatment were also prepared as a control. After the treatments, all the samples were air-dried, sanded, weighed, and installed in the research location. The results showed that four subterranean termite species, i.e., Schedorhinotermes sp., Microtermes sp., Capritermes sp., and Macrotermes sp, were found attacking the wood samples. The highest attack frequency and the highest damage intensity were found in wood samples with hot vapor pressure treatment. Based on the scoring, the preeminent treatment for the wood samples was the hot vapor pressured treatment.

“…Intensitas cahaya mempengaruhi proses fotosintesis, dimana tingginya tingkat fotosintesis pada tanaman akan meningkatkan pertumbuhan xylem dan floem sekunder yang berkembang dari jaringan meristem sekunder sebagai ukuran pertambahan diameter pohon (Putri, 2009). Selain itu, intensitas cahaya yang rendah karena naungan yang terlalu rapat bagi jenis yang memerlukan cahaya (intoleran) akan menyebabkan etiolasi (Herdiana, Siahaan, & Rahman, 2008). Sebaliknya intensitas cahaya yang berlebihan akan menyebabkan gangguan pada pertumbuh-an bahkan kematian bagi tanaman yang toleran.…”

“…Naungan berpengarh kurang baik pada pertumbuhan maupun hasi tanaman kacang merah, dimana semakin tinggi tingkat naungan pertumbuhan tanaman dan hasil seperti jumlah daun per tanaman, jumlah cabang per tanaman, persentase jumlah polong isi per tanaman,jumlah polong isi per tanaman, jumlah polong per tanaman, bobot biji kering per tanaman, bobot 100 butir biji , kecuali tinggi tanaman semakin menurun, kecuali pada parameter tinggi tanaman dimana naungan yang semakin rapat membuat tanaman lebih tinggi. Kerapatan naungan mengakibatkan pertumbuhan tanaman kurang baik (Herdiana et al 2008). Naungan yang terlalu rapat bagi jenis tanaman yang memerlukan cahaya akan menyebabkan etiolasi, gangguan pada pertumbuhan bahkan kematian bagi tanaman yang toleran.…”

The research aims to obtain varieties of red beans was tolerant oflow light intensity under this shade.The research implemented in the experimental garden UNWIM BojongSeungit campus, from late June to early September 2016, with a height of 850 meters above sea level and precipitation type C (Dampish ).The experimental design used was split plot design consisting of 16 treatments and 4 Deuteronomy .Treatment consists of two levels : size of the shade (P), p0 = 0%Shade, p1 = 50% Shade, p2 = 65% Shade, p3 = 75%Shade, and varieties (v), v1 = Garut and v2 = Tasik.The results of this experiment showed the effect of growth and different results in higher plants in shade 65% and 0% in the varieties of Garut and Tasik age 35 days after planting, number of leaves per plant and the number of branches per plant at 28 days after planting in the shade of 75%, the number of pods contents per plant and the number of pods per plant in the shade of 0% whereas 50% shade highest yield of dry grain weight per plant, weight of 100 grains of seed varieties Garut and percentage (%) number of pods per plant were highest in varieties Tasik Varieties of Garut and Tasik are sensitive to shade 75%, moderate to 65% shade and still tolerant to shade 50%.
