The research was conducted in Mount Rinjani National Park, Lombok Timur, to observe the daily activities of Long-tailed macaque in utilizing their habitat and vocalization analysis as a hallmark of species. The Long-tailed macaque’ activities were analyzed using the scan sampling method. Ten (10) individuals of Long-tailed macaque were observed. The results showed that the observed activities of Long-tailed macaque were feeding, sleeping, inactive, grooming, mating, moving, excretion, playing, making sound, and agonistic (fighting). The average percentage of Long-tailed macaque observed was feeding (10.1%), sleeping (9%), inactive (9.4%), grooming (14.9%), mating (8.5%), moving (11.1%), excretion (7.9%), playing (9.7%), making sound (9.5%), and agonistic (9.9%). The daily activities can be as a reference in detecting the ‘species’ of the Long-tailed macaque. To support the population of this species, especially for long-term survival, the manager of the Rinjani Nasional Park should preserve the forest with conservation of natural forests and wildlife or biodiversity conservation and ecotourism, also prevent littering and illegal activities.

Pemanasan global menjadi faktor penyebab perubahan iklim dunia.  Dampak pemanasan global salah satunya adalah mencairnya es di kutub yang menyebabkan naiknya permukaan air laut yang menjadi ancaman bagi ekosistem pesisir yang salah satunya adalah ekosistem hutan mangrove.  Peran ekosistem mangrove dalam mitigasi pemanasan global adalah dengan mengurangi konsentrasi CO2 yang disimpan dalam bentuk cadangan karbon.  Kawasan mangrove Tanjung Batu merupakan bagian dari Kawasan Ekosistem Esensial (KEE) Koridor Mangrove Teluk Lembar yang memiliki peran penting dalam upaya konservasi mangrove khususnya di Kabupaten Lombok Barat.  Tujuan dari penelitian ini adalah untuk menganalisis biomassa dan serapan karbon hutan mangrove Tanjung Batu.  Pengambilan data biomassa dilakukan dengan petak ukur ganda dengan metode jalur berpetak.  Data vegetasi mangrove dianalisis menggunakan persamaan allometrik untuk analisis biomassa, cadangan karbon dan serapan karbon.  Berdasarkah hasil penelitian, total estimasi nilai biomassa yang dihasilkan oleh hutan mangrove  Tanjung Batu yaitu 1621,74 ton dan jenis Rhizophora stylosa menjadi penyumbang terbesarnya.  Total estimasi cadangan karbon di hutan mangrove Tanjung Batu yaitu 810,87 ton dan serapan karbonnya 3048,87 ton CO2 dan jenis Rhizophora stylosa menjadi penyumbang terbesarnya.

There is four hiking track in the Gunung Rinjani National Park area, namely Senaru, Sembalun, Timbanuh, and Aik Berik. In 2016 there were 93,018 visitors to Mount Rinjani National Park. A large number of a visitor can be a potential because it contributes to state revenues, but on the other side, the presence of waste become manager's homework because the higher number of visitor occurs waste also getting bigger. This study aim is to develop a waste management plan in the hiking track of Mount Rinjani National Park.

Kelulut cultivation (meliponiculture) has the potential to be developed in West Nusa Tenggara (NTB) due to the availability of abundant natural bee forage resources. The meliponiculture in NTB is generally still on a home garden-based scale. However, the lack of public knowledge about the variety of plants that produce nectar, pollen, and resin throughout the year is an obstacle to the development of meliponiculture. This study aims to identify the variety of the bee forage and identify constraints and opportunities for developing its cultivation. The results showed that 30 species of plants have the potential as bee forage sources, consisting of seasonal and herbaceous plants. All these plants produce pollen, in which 27 species produce pollen and nectar, and only six can produce all pollen, nectar, and resin. Based on the identification results, there are five obstacles and five opportunities in meliponiculture at the research site. The main obstacle was the lack of knowledge about the economic and ecological prospects of meliponiculture. At the same time, the opportunity for cultivation is enormous due to the availability of abundant bee forage resources. Therefore, it is necessary to conduct counseling and training on the economic and ecological prospects of meliponiculture, potential food sources, colony maintenance, and post-harvest processing.

Tahura is a nature conservation area with a purpose to collecting natural or non-native plants and or animals, native and or non-native species, which are utilized for research, science, education, supporting cultivation, culture, tourism and recreation. As a conservation area whose territory is directly adjacent to the community, Nuraksa Forest Park is a source of economy and life for the surrounding community so that it can be said that there is community dependence on land in the area. This is a challenge in managing the area. In an effort to provide management direction so that the functions and benefits that have been regulated in the legislation and the achievement of the goals that have been formulated can be achieved, the perceived need for activities to identify problems and management strategies of Nuraksa Forest Park. The research was carried out through a series of activities, which consisted of literature studies, interviews and field surveys. The results of the SWOT analysis of the management of Nuraksa Forest Park are in quadrant III. This shows that Nuraksa Forest Park faces enormous opportunities, but on the other hand faces several internal obstacles / weaknesses. The strategy that must be implemented is to minimize the internal problems of the institution so that it can seize better opportunities.
