AbstractA screw tree (Helicteres isoraL.) is a small/large shrub species that grows and spreads in many Asian countries, including Indonesia (NTT and Maluku). It is a medicinal plant commonly used to treat many diseases, such as bleeding and constipation. This study aimed to determine the effect of Arbuscular Mycorrhizal (AM) fungi and planting media on the growth of screw tree seedlings in a nursery. This research was conducted at Bogor Forest Research and Development Center’s nursery, Indonesia. This study consisted of two factors: AM fungi with three levels, namely control,Glomus aggregatumandGlomus clarumand growth media with two levels, namely mixed media of soil: rice husk charcoal (2:1) and mixed soil of media: rice husk charcoal: cocopeat (2:1:1). The results showed that treatment ofG. aggregatumand soil mixed of media: rice husk charcoal: cocopeat (2:1:1) was significantly different from other treatments except forG. clarumand soil mixture of media: rice husk charcoal: cocopeat (2:1:1) that significantly increased height, diameter and dry weight of seedlings and the values were 97, 56, 126 and 46, 37, 127% compared to the control. Mycorrhizal dependency of screw tree was very high (126 and 127%). Generally, interaction treatment ofG. clarumand mixed media of soil: rice husk charcoal: cocopeat (2:1:1) increased the growth of 11-month-old screw tree in the nursery.

Abstract
This paper explores the role of Bogor Botanic Gardens (BBG) as a form of Nature-Based Solution (NBS) to mitigate Urban Heat Islands (UHI). Time series analysis of LANDSAT 8 OLI thermal band and Normalized Difference Vegetation Index (NDVI) was done from 2013 to 2020 using Google Earth Engine. Land Surface Temperature (LST) from Bogor and BBG were calculated, compared, and annual UHI areas were derived. The relationship of LST and NDVI were also explored annually to describe the effect of vegetation towards LST with linear regression. Overall, Bogor experiences a decrease of mean LST from 30.67°C and a maximum of 39.14°C in 2013 to 27.07°C and a maximum of 34.35°C in 2020. However, the inside of BBG is cooler with temperature ranging from 28.41°C and a maximum of 35.62°C in 2013 to 24.25°C and a maximum of 29.41°C in 2020. This is an effect of vegetation inside the BBG that regulate microclimate in its surrounding. It can be seen in the negative correlation between NDVI and LST observed with r2 ranging from 0.27 to 0.82. While UHI areas tended to increase from 8220 ha in 2013 to 8926 ha in 2020, BBG consistently acts as an urban cool island in the middle of UHI. Therefore, heat mitigation is proven to be one of the environmental services provided by BBG.

Abstract
Timber harvesting in natural production forests in Indonesia is still carried out to his day in the form of a bussines license for the utilization of timber forest products-natural forests (IUPHHK-HA). IUPHHK-HA holders have not fully implemented Reduced Impact Logging (RIL). Forest harvesting activities consisting of felling, skidding, bucking, loading, unloading, and transportation of logs are aimed at without significantly disturbing log production and its environment. The purpose of this review is to provide information on RIL in Indonesia. The collection of data was done by using a desk study. Data on productivity, efficiency, costs, damage to the residual stands, and the impact of RIL on emissions were collected. Several research results showed that: (1) logging productivities generally decreased when compared to Conventional Logging (CL), (2) logging efficiency generally increased when compared to CL, (3) logging costs generally increased in the short term, (4) residual stand damages generally reduced when compared to CL, and (5) RIL has potential to reduce emissions compared to CL. It is necessary to do the following: harvest planning such as mapping and distribution of trees, skid trail alignment, design of landings; harvest preparation such as the opening of skid trails, opening of landing places; harvesting such as determining felling direction, felling, skidding, and closure of harvesting such as closure of skid trails and landings.

Abstract
Today’s stingless bees are in great demand by beekeepers in Lombok. Besides producing honey, it also produces propolis which has more value. Propolis or bee glue is a substance produced by honey bees collected from the top young leaves mixed with the saliva, patch, and hive sterilization. This substance could be used for antibacterial, antivirus, antifungal, and anti-protozoa. In Lombok, apiculture for stingless bees has spread in almost every district. Northern Lombok, West Lombok, and East Lombok were the first three locations that developed stingless bees. This study aimed to identify the species of stingless bees and their propolis productivity and characteristics produced by each species. There were two species of stingless bees cultivated by the people of Lombok, Trigona clypearis and Trigona sapiens. The development of science, genus Trigona changed nomenclature into Tetragonula. The yield of propolis through extraction using water or Aqueous Extraction Propolis (AEP) produced by T. clypearis was 34-55% and T. sapiens was in the range of 3-24%. The flavonoid content equivalent to quercetin in propolis produced by T. sapiens as vary as T. clypearis. The results of this study could be used as a baseline for other propolis extraction activities to produce propolis more marketable.

AbstractIndonesia is a mega-biodiversity country that grows about 4000 timber producer tree species in tropical rain forest. The comprehensive information of wood properties and quality is important in managing the natural resources sustainably. However, stem in basic properties studies of wood from the natural forest is limited because of some difficulties in harvesting until the transportation process. Hence, study the wood branches becomes a solution, as sometimes wood core samples are not adequate. The question was whether the branch properties could represent the main stem properties? Wood anatomy is an important wood property that can predict the other properties, for instance, the physical and mechanical properties, that determine the effective use of this material. This paper aims to present the comparison of wood anatomical properties of branches and main stem of seven commercial wood species. Quantitative and qualitative anatomical structures were investigated according to the International Association of Wood Anatomist (IAWA) Committee. Result shows that the quantitative wood anatomy of four samples (Mimba, Leda, Jabon, and Bintangur) was statistically different, while only one parameter in Tusam, Mindi, and Khaya was different. Accordingly, it can be concluded that studying the wood properties could be carried out using branch effectively.

Abstract
Thirty Hills National Park (THNP) located in Riau province has a local community, namely Talang Mamak tribes, who live inside its territory. To increase their livelihood and reduce their dependency on forest resources, THNP conducts an empowerment activity as an alternative for living through meliponiculture. Meliponiculture is a practice of beekeeping using stingless bees. The objective of this study is to evaluate the effectivity of meliponiculture as an empowerment activity program. This study was conducted at five communities of Talang Mamak tribes during 2019, namely Tualang, Bangayauan, Nunusan, Air Bomban, and Sadan. Provide to assist and initiate their enthusiasm in this program. Honey production and their capability in maintaining the stingless bees are respond variables that are assessed to determine the effectivity of the program. Results reveal that honey production at five communities are highly increase (avg. 63.12%) in the second semester except in Sadan that is slightly decline (9,89%) even though Sadan have the highest honey production in the first semester as 5 kgs. Furthermore, Air Bomban produces 16.3 kg in the second semester and have the highest honey production in the second semester or increase 91.06% compare to first semester. In addition, there is only in Bengayauan that only have six colonies that have not produced honey yet from total fiveteen colonies. Meanwhile, sixty colonies of stingless bees that are placed at the other four communities are already active in producing honey and show that the communities are able to maintain those colonies. The consistency and marketing are needed to guarantee the effectivity of this empowerment program in the following years.

Abstract
The management of protection forests in KPH Yogyakarta has involved the surrounding community. Community involvement is expected to keep forest sustainability and contribute to the surrounding community’s income. Community engagement activities in the protection forest at RPH Mangunan have been developed long time before the KPH Yogyakarta was formed. Several social forestry activities was designed by utilizing forest land to involve the community in protection forests, especially in RPH Mangunan. Activities with the community on KPH land are permitted as long as the crops and trees are not disturbed. This paper aims to identify community involvement in RPH Mangunan and calculate the economic contribution of each land area used by the community. The research was conducted in July-August 2018. The collection of socio-economic data are obtained through household surveys of KPH land users, in-depth interviews with key stakeholders and Focus Group Discussion (FGD) of parties involved in KPH land management. The income from managing the KPH land is still below the needs of one household based on Yogyakarta provincial minimum wage. Apart from carrying out agricultural activities, some community members have other sources of livelihood. To increase the community’s income and support forest sustainability, some strategies need to be implemented.

Abstract
Gender discourse in Indonesia is currently developing very rapidly. On one hand, gender activists have focused on gender mainstreaming. On the other hand, the socio-cultural reality in Indonesia persists with the old traditional construction of power relations between men and women. Feminists fight for justice and inclusiveness for women. However, their struggle must be confronted with the fact that the prevailing socio-cultural norms still tend to be male-dominant. This paper will reveal how the social reality of power relations in the realm of gender is constructed in rural areas in Indonesia. The subjects studied are families at the clan level who are managing sustainable bamboo forestry in Ngadha Regency, East Nusa Tenggara, Indonesia. The research was conducted in 2019-2021. The methods used are participatory rural appraisal (PRA), in-depth interviews, and observation as participants. Time allocation is used as the object of this study to create gender mapping. The analysis is carried out using a social construction theory. This study concluded that the clan of Neguwulacan adopt the HBL system. This is reflected in the emergence of local initiatives to manage finances, the workforce, groups, as well as build and implement them at the clan level. The gender relations that exist in SBF practice at the clan of Neguwula are relative. First, in terms of family lines, women obtain benefits because could hold matrilineal law. Political decisions remain in the hands of women. Second, practically speaking, women work twice as much in domestic and commercial work. Third, in some cases, deliberation is put forward for a fair division of labor. At this point, inclusiveness emerges as a reality that colors gender relations.
