Most of the people live in Ngancar village, Pitu sub-district, Ngawi  district, East Java  are farmers. They cultivate crops not only on their privately-owned land but also on Perhutani’s forest land which is dominated by old teak stands. One of the problem in cultivating agricultural crops under old teak stands is the crown cover. It will significantly reduce the light intensity received by crops, and consequently decreasing the yield potential. Knowledge about the shade tolerant species and various silvicultural techniques should be understood and practiced by farmers, so that they can optimize the land use and achieve the high yield. Community service activities by Team of Silviculture Department, Faculty of Forestry UGM are carried out by establishing demonstration plot, maintenance, evaluation of plant growth and health, as well as problem identification and evaluation of successful cultivation under agroforestry system. Observation, focus group discussion, interview, questionnaire and counselling are implemented in order to collect related data and information. This community service activity uses descriptive qualitative approach. Outcome from this community service activity is recommendation of several shade tolerant species which can be cultivated under the old stands such as longan, avocado, and ginger. In addition, silvicultural treatment such as embroidery, weeding, and pest and disease control should be intensively managed  in agroforestry practice in order to achieve optimal yield productivity.

Desa Pitu, located along the Bengawan Solo River in Ngawi, Jawa Timur, is one of the regions with a high risk of flooding due to human activities like as settlement and intensive agriculture along the riverbanks. This phenomena causes soil erosion and crop failure, which reduces the income of the Pitu local community. A rehabilitation strategy is required to resolve this issue, not only for the recovery of the riverbanks but also for the enhancement of the local community’s revenue. The objective of this community activity is to educate the public about the use of bamboo species in riverbank restoration (Dendrocalamus asper). Bamboo is selected because it has both ecological and socioeconomic benefits. This project was conducted between March and September of 2022 on the Grojogan riverbanks, Bengawan Solo River, Desa Pitu. This exercise utilized Focus Group Discussion, lecture, and practice or training as its methods. The population of Desa Pitu might simply adopt bamboo species and cultivate them along riverbanks. The community and the community service team from the Silviculture Department planted 1,000 bamboo seedlings. The survival rate of bamboo plantations exceeded eighty percent, and new shoots grew swiftly (5 - 15 cm for 5 months). Training in bamboo growing and bamboo product processing improved their skills well. The community generates bamboo seedlings successfully through vegetative propagation. In addition, three local communities in Cebongan, Sleman, and Yogyakarta participated in a four-day bamboo processing training program. They were also producing some tables, chairs, and handicrafts with success (woven bamboo).

A B S T R A C TCoastal sandy soil without trees is characterized by a high temperature, salinity, strong wind, as well as lacking nutrient content. The environmental conditions limit affects the variety of undergrowths. This research aimed to figure out the composition, distribution pattern, habitat condition and rooting of brushes species found on coastal sandy areas at the Lemburpurwo. The study was conducted using line transect method applying systematic sampling with a random start. The observations of undergrowths were carried out on the three types of threads, i.e., near the sea, under the beach-she-oak stands locally know as Cemara Udang, and behind the beach-she-oak stands with no trees. Transects were made perpendicular approximately 53 m from the shoreline, and the distance between transects was 95 m. A series of 2x2 m 2 plots were laid diagonally (zigzag) across the transect line for undergrowths sample collection. 81 plots were taken, represented the Lemburpurwo area covering 72,960 m 2 . Scrubs plant species were identified, the length and number of roots were measured, environmental conditions and soil condition including pH, conductivity, total N, available P, and available K were also measured. Lembupurwo coastal sandy area was inhabited by 20 species of 13 families of undergrowths. Three species were found randomly distributed, and 17 species were found in a clustered distribution pattern. Spinifex littoralis has the longest root as well as the largest number of roots, especially in open areas. The measured values of soil pH and conductivity below the stands were 6.41 and 32.23 µs/cm lower compared to near the sea site. Total N and available P of the soil under beach-she-oak stands were 0.03% and 5.05 ppm which higher than the other two locations.
