A spawning area of Lutjanus bohar, a marine fish of high economic value, is one of the eight important resources of Wakatobi and also a critical habitat in the waters of Hoga Island. For protecting the area, Wakatobi National Park has stated the area as a tourism zone (no-take zone). This research was conducted to evaluate progress toward spawning-area protection by examine number of individuals, length size of fish, and trespassing cases that occurred in the spawning area. Research was carried out in 2018-2019. Number of individuals and size of fish werecollected by referring to the monitoring guidelines for the Spawning Aggregation Site (SPAGs), and observations with an Underwater Visual Census. Trespassing case data were collected by interview key persons. Descriptive analysis was used to describe progress toward spawning-area protection. The results indicate that the protection effort of spawning area has a positive impact in increasing number of individuals and length of Lutjanus bohar. However, number of trespassing cases in the waters of Hoga Island still shows an increase. Fishing activities are the most trespassing cases occurred in thespawningarea. This approach should be implemented to evaluate the progress towards protection efforts, besides increasing the number of patrols and socialization with fishermen to increase their awareness.

Earthworms have a role as bioindicators so that their existence is very sensitive to changes in the environment. The decreasing of land quality caused by continuous use (horticultural agriculture) will also decrease the diversity of earthworms. To anticipate degradation of land quality, the land needs to be rested (bero) so that it will facilitate natural recovery. Indicators of land restoration include the diversity and importance index of earthworms. Therefore, the research aim wasto determine the diversity of earthworm in the fallow system lands at KelimutuNational Parkareas. The monolith random sampling method at three soil depths was applied to several fields with different fallow periods (5, 10, 15 and 20 years) to measure importance value index, diversity index, evenness, density, and earthworm biomass. The results showed that there were 4 types of earthworms found in the land given, namely Pontoscolex, Megascolex, Lumbricus and Perithima. Pontoscolex dominates which is indicated by the highest importance value index. While the diversity of earthworms washigher in fallow land with a duration period of 5 and 20 years. The duration of the fallow period is also shown to affect populations of earthworms but has no effect on its biomass. For soil depths not seen no effect at each depth. The results of this study further strengthen the evidence that the application of the bero period can improve land quality by increasing the earthworm population so that land productivity can be maintained.

Timber harvesting activities can cause damage to residual stands, this can occur due to improper timber harvesting techniques. The study was conducted at one of PT Tunas Timber Lestari’s IUPHHK-HA in Papua Province. The results showed that: 1). The number of trees felled and skidded on 3 logging compartment with each of the 3 plot of observation sample has an area of 2 ha (the total area of the research is 18 ha) is 16 trees on average; 2). The average number of residual stand (trees with a diameter of ≥ 20 cm) damaged by logging is 26 trees (13.00%) per ha with details of damage to canopy of 4 trees (15.39%), broken branches of 13 trees (50.00%), the trunk wound of 2 trees (7.69%) and the collapsed/tilted of 7 trees (26.92%); 3). Damage to the residual stand in felling is caused more by the lack of skilled chainsaw operators in determining felling direction; 4) Damage to residual stands due to skidding is an average of 23 trees (9.99%) per ha, with details of 1 trees buttress (4.4%), wounds injuries of 7 trees steam (2.97) and collapsed/slanted 15 trees (65.2%); and 5). The cause of damage to the residual stand on skidding is that the skid trail has not been made and the skid tractor maneuvers too often.

Rattan is one of the promising non-timber forest products which grow widely in Indonesia. The occurrence of rattan species, especially the commercial species, is threatened due to illegal over-exploitation. The study has been done in the Bukit Tiban Protection Forest (BTPF) to investigate the occurrence of rattan species and observe the characteristic of morphology properties and their utilization. In this study, a descriptive exploration method was applied and we performed an interview with local people in the field regarding the utilization. Morphological characteristics observed including habitus, leaves (such as color, leaflets, leaf arrangement, knee, ocrea, and climbing organ/cirrus/flagellum), and fruit. The identification key, illustrations, as well as the diagnostic character of each species were presented. Ten species of rattans were found in the BTPF, namely Calamussp.1 (Daemonorops verticillaris(Griff.) Martius), Calamussp.2 (Calamus rugosusBeccari), rotan sabut (Daemonorops sabutBeccari), rotan buah kecil (Daemonorops didymophyllaBeccari), Plectocomiasp. (Plectocomia elongate Martius ex Blume), rotan bukit (Daemonorops sepalBeccari), rotan dahan (Korthalsia rostrataBlume), Calamussp.5 (Calamus spectatissimusFurtado), Calamussp. (Daemonorops longipes(Griff.) Martius), and Calamus sp.6 (Calamus tanakadateiFurtado). Those ten species of rattan are potentially used for handicrafts, basketry, and ropes. Only five of ten species of rattan have been used commercially.

Community involvement in forest and land fires management at site level is important due to the community can play a central role in preventing forest and land fires. One of the programs that involves the community in controlling forest and land fires is the Fire Care Community or Masyarakat Peduli Api (MPA). The MPA institution is a group consisting of members who join voluntarily. As a organization, MPA requires leadership that is able to mobilize members to carry out their role. MPA Wonorejo in Musi Banyuasin Regency, South Sumatra Province, is one of the successful MPAs. In this case the leader of MPA Wonorejo received the Wana Lestari award from the Minister of Environment and Forestry in 2018. With the case study method, this research was conducted to explore the leadership style that has been applied to the Wonorejo MPA. The results showed that MPA Wonorejo's leadership style is a transformational style with charismatic characters, inspires members, encourages intellectuality and provides individual attention. The leader of MPA has an important role in mobilizing MPA members to play a role in fire control.

Nickel mine is one of the contributors foreign to exchange earners in Indonesia. However, the former mining area creates a complex problem in the physical, chemical, and biological soil properties which directly affect the ability of plant growth for restoration. The planting of legume species, one of them is sengon laut (Falcataria moluccana), in the reclamation of ex-mining land aims to improve soil properties. Legume plants have low C/N ratio so the introduction of nitrogen-fixing soil microorganisms is one alternative that can be used to improvesoil fertility. Nitrogen fixing bacteria can provide nitrogen compounds that can be directly utilized by plants. In addition, the utilization of fast-growing species such as sengon laut is suitable for rehabilitation of critical lands. This study aims to isolate and characterize symbiotic nitrogen fixation bacteria so it can be made as inoculum and applied on revegetation in nickel postmining area. Five bacterial isolates were obtained from nodules of sengon laut belonging to genus Rhizobium(3 isolates) and Bradyrhizobium(2 isolates). All isolates obtained were rod-shaped, Gram negative and did not have endospores. Physiological tests showed that all isolates were aerobic, motile, grew optimally on YEMA media at pH 6 and 7, but did not grow at pH 4. Initial potential testof Acetylen Reduction Assay and IAA test showed that A3.1 SL 5 isolate has the highest value (9.01 ppm and 0.447 ppm) and potential to be inoculum.

Purwodadi Botanic Garden (KR Purwodadi) is an exsitu conservation institution for dry climate lowland plants aiming at saving and protecting biodiversity from extinction. In supporting exsitu conservation efforts, plant exploration activities in their natural habitat need to be carried out. Alas Purwo National Park has a lowland forest area with abundant plant diversity. In addition to functioning as a conservation forest, this area is also a natural and religious tourist attraction, so it is likely to undergo ecosystem damage. Therefore, this plant diversity study with theactivity of plants exploration and collection was carried out for the purpose of ex situ conservation in KR Purwodadi.This study was conducted in August to September 2019 using an explorative method. A total of 24 species were obtained, of which 8 species were not yet cultivated by KR Purwodadi. Besides, there were 5 species included in the IUCN red list, namely Aglaonema simplex, Brucea javanica, Cycas rumphii, Melanolepis multiglandulosa, and Musa acuminata. This study has increased the number of plant collections in KR Purwodadi and contribute positively to the comprehensiveness of plant species data in Alas Purwo National Park.
