    Bulakbaru village in JeparaDistrict is a village located in the northeastern coast of Java Sea. This village is prone to abrasion. Each year its land was reduced by between 50 to 100 meters. The existing vegetation in the area is only some mangroves, so that the condition of this coastal area has become more extreme. This condition requires efforts to improve and manage the coastal area potential with a variety of methods. Coastal rehabilitation requires strong human resources, equipped with appropriate science and technology for the coastal community. The research aims to encourage karang tarunato manage coastal potential and transfer simple technology for the rehabilitation of the coastal area so that the community can participate actively in preserving a sustainable environment. This programcomprises methods of public education, consultation, diffusion of science and technology, training and mediation. In the implementation of the program it was evident that the community, particularly members of karangtaruna, actively participated in all activities so that they could learn the science and technology and became more open-minded in managing the potential of their coastal village. Large portion of the the coastal rehabilitation technology can be transfered to the community.  The village community was able to realize the importance of mutual cooperation to manage their environment in order that it can be sustainable

    Pitu Village, Pitu subdistrict located along the Bengawan Solo River in Ngawi, East Java, 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, Pitu Village, and Pitu Subdistrict. 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)

    Coastal area with its high temperature, high soil salinity, strong winds and sandy soil structure may cause environment condition which limits the survival and growth of undergrowth. Such an extreme environment may also affect the pattern of distribution of the undergrowth, such as a random, regular or clustered pattern. This study aims to determine the composition and distribution patterns of the undergrowth under Cemara Udang stand in a coastal area at Karanggadung, Kebumen, as well as the function of the undergrowth. Data was collected using line transect method, in which a systematic sampling with random start was utilized to determine sample plots locations. Line transects were perpendicularly made for 5 m in wide and 50 m in length to the shoreline. The distance between lines was 100 m. Each of the lines was divided into 10�10 m plots, and undergrowth were observed from 2�2 m sample plots located diagonally in the 10�10 m plots. The total number of the sample plots is 30 plots. Types of undergrowth were indentified and the coverage magnitudes of each species were estimated. Data was analyzed by calculating Importance Value Index (IVI) of each of the species, as well as Dispersion Index and Chi-Square for determining the distribution pattern. There were 15 undergrowth species (within 11 families) found in the Cemara Udang stand. Spinifex littoralis, Ermeleria sonchyfolia, Isachne pulhella Cyperus pygmaeus and Calothropis gigantea dominated the area, with the IVI of 98.7 %, 16.8 %, 15.6 %, 14.1 %, and 11.5 %, respectively, while 10 other species less than 10 %. Among the species, 4 species distributed in random pattern and 11 species distributed in clumped pattern. The undergrowth species were useful and beneficial for the community in term of life support and ecology. The undergrowth under Cemara Udang Stand in a Coastal Area at Karanggadung, Kebumen were used for animal fodder, medicine and as sand binder in the sand dunes. The environmental factors strongly affected the presence of the undergrowth species

    Optimalisasi Penggunaan Lahan dengan Sistem Agroforestri di Desa Ngancar, Ngawi: Land Use Optimization using Agroforestry System in Ngancar Village, Ngawi

    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
