EFFECTIVENESS OF AGROFORESTRY-BASED WATERSHED REHABILITATION IN SUPPORTING CARBON DIOXIDE REDUCTION IN THE MANAGEMENT AREA OF KTH HIJAU MAKMUR, WEST LOMBOK
Carbon dioxide (CO2) contributes significantly to global warming, leading to climate change that impacts human life. To mitigate emissions, Indonesia has committed to reducing greenhouse gas (GHG) emissions by 29% independently and 41% with international support by 2030, as outlined in its Nationally Determined Contribution (NDC). One of the strategies implemented is the Indonesia’s Forestry and Other Land Uses (FoLU) Net Sink 2030 program, prioritizing the forestry and land-use sectors. This study evaluates the effectiveness of agroforestry-based watershed rehabilitation activities in the area managed by Forest Famers Group (KTH) Hijau Makmur, Gelangsar Village, West Lombok Regency. The results show a high plant density level (>400–600 plants/ha), dominated by high-economic-value multipurpose tree species (MPTS) such as durian, mangosteen, avocado, and stink bean. The observed plants are categorized as seedlings and saplings (1–3 years old, height >1.5 meters, trunk diameter <10 cm). As the plants mature, their stem volume and canopy area are expected to enhance carbon sequestration through stems, roots, litter, and necromass. These findings indicate that agroforestry practices not only provide economic benefits but also support climate change mitigation by increasing carbon storage potential.

AXIAL VARIATION IN THE PHYSICAL AND MECHANICAL PROPERTIES OF MINDI WOOD (Melia azedarach LINN.) FROM SENANGGALIH VILLAGE, EAST LOMBOK REGENCY
The demand for commercial timber in Indonesia continues to rise, while the availability of forest resources is steadily declining, both in terms of production forest area and wood quality. Many native wood species remain underutilized in the Indonesian wood industry due to limited information regarding their properties. One such species, Mindi wood (Melia azedarach Linn.), has been used by local communities but is not widely recognized as a commercial timber alternative. Mindi wood holds potential as a substitute for high-quality commercial timber; however, research on its physical and mechanical properties remains scarce. This study aims to evaluate the axial variation in the physical and mechanical properties of Mindi wood from Senanggalih Village, East Lombok Regency, and to assess the influence of axial position on these properties. The study employed a non-factorial Completely Randomized Design (CRD) with three axial sections (base, middle, and top) as treatments, each replicated three times. Results indicated that axial position significantly affected certain physical properties, including kiln-dry specific gravity, radial shrinkage (from fresh to kiln-dry), and longitudinal swelling (from air-dry to wet). However, no significant effect was observed on moisture content (fresh air or air-dry), fresh specific gravity, air-dry density, or shrinkage and swelling in the tangential, radial, and longitudinal directions for various moisture conditions. In terms of mechanical properties, no significant effect of axial position was found on Modulus of Elasticity (MoE) and Modulus of Rupture (MoR). These findings suggest that Mindi wood is suitable for light construction applications such as furniture manufacturing, as well as for composite wood products including plywood, particleboard, and fiberboard.

PHYSICAL PROPERTIES OF CEMENT PARTICLE BOARD FROM SAWDUST OF KEMPAS WOOD (Koompassia malaccensis Maing)
The increasing demand for wood and the diminishing potential of forests necessitate the efficient and prudent use of wood resources. To address this issue, alternatives to wood are required, and one such option is particleboard made from wood sawdust. The abundance of waste sawdust from kempas wood (Koompassia malaccensis Maing) is noteworthy, yet this waste material remains underutilized. The objective of this research is to determine: i.) the influence of the particle-to-cement ratio, ii.) the effect of different compressive pressures on the physical properties of kempas wood sawdust particleboard, and iii.) the interaction between the particle-to-cement ratio and compressive pressure on the physical properties of kempas wood sawdust particleboard. In this study, a factorial completely randomized design with two factors was employed. The first factor is the particle-to-cement ratio (P), consisting of three levels: P1 (1:3), P2 (1:4), and P3 (1:5). The second factor is the difference in compressive pressure (T), comprising two levels: T1 (25 kg/cm²) and T2 (35 kg/cm²). There are a total of 6 treatments resulting from the combination of these two factors, repeated three times, and yielding 18 test samples. The results indicate that the ratio of cement to particles only significantly affects density at a significance level of 0.05 but does not impact moisture content and thickness swelling of kempas wood sawdust particleboard. The variation in compressive pressure does not influence any of the physical properties (density, moisture content, and thickness swelling) of the particleboard. Furthermore, the interaction between the particle-to-cement ratio and compressive pressure does not significantly affect any of the physical properties (density, moisture content, and thickness swelling) of kempas wood sawdust particleboard.

REPTILE BIODIVERSITY IN THE INTEGRATED FIELD LABORATORY UNIVERSITY OF LAMPUNG
Reptiles are cold-blooded animals that need to be known and their evenness as an environmental bio-indicator. The purpose of the study was to determine the diversity of species and the diversity of reptiles. The research was conducted in December 2020-January 2021 at the Integrated Field Laboratory of the University of Lampung. The research data was collected using the Visual Encounter Survey (VES) method with a combination of the Time Search method. Then the results were analyzed quantitatively using the Shannon-Wiener diversity index and the type mapping index. The results showed that there were five types of reptiles observed, namely the wall lizard (Hemidactylus frenatus), garden lizard (Eutropis multifasciata), striped blackhead snake (Hemalopsis buccata), grass lizard (Takydromus sexlineatus) and welang snake (Bungarus candidus) in the medium category. This is because the habitat still has sufficient food availability, whereas since human activities the habitat has been slightly disturbed. In the third habitat, the distribution of reptiles is even and the distribution of reptile species is included in the category of stable community. The reptile species found were not different because the distance in the three habitats was not too far away which made it easier for the species to move around. The balance of the campus environment can be determined by monitoring and researching the existence of reptiles at the University of Lampung. In addition, other efforts to reduce hunting and illegal trade in reptiles provide protected status for reptile species.

The design used in this study is the completely randomized design (CRD), with factorials consisting of two factors and three replications, giving the total samples of the study of 48 treatments. The first factor is the hormone (R) consists of 4 levels, namely control 0 ppm (), 100 ppm (), 200 ppm (), and 300 ppm (). The second factor is the growing media (M) consists of 4 levels, namely soil (), soil + cocopeat (), sand + cocopeat (), and cocopeat (). The results show that the use of Rootone-F hormone and planting media have no significant effect on all research parameters (namely: seedling height, seed diameter, number of leaves, root length, and live percentage) of cajuput (Melaleuca cajuputi).
SPECIES AND BENEFITS OF Ficus spp. IN THE COLLECTION BLOCK OF TAHURA WAR LAMPUNG PROVINCE
Plants belonging to the genus Ficus have many benefits for the life of the people and animals in it for example as water system guard, absorbing CO2, feed sources and habitat for various species of animals and has potential as a traditional medicine.

IDENTIFICATION AND CONTROL OF PESTS AND DISEASES IN THE NURSERY OF PT NATARANG MINING TANGGAMUS DISTRICT
Quality seedlings are needed to increase land reclamation and rehabilitation activities. Quality seedlings are genetically, physically and physiologically superior seedlings so that they are able to adapt to critical environments. Seedlings are said to be of friendly quality, having normal growth, straight trunk, healthy and free from pests and diseases. One way to provide quality seedlings is to build a nursery like the one at PT Natarang Mining. However, the seedlings produced by this nursery are still of low quality because they are attacked by pests and diseases. In this study, an investigation of pests and diseases in the nursery of PT Natarang Mining was carried out. Data were collected by random sampling with a sampling intensity of 10% so that the sample used was 1,210 forest plant seedlings. Then carried out observations on the forest plant seedlings to see whether there are defects caused by pests and diseases. From the observations it is known that the pests and diseases that attack plant seedlings in the nursery forest of PT Natarang Mining are dominated by snail pests (26%) and leaf spot disease (16%). These pests and diseases can be overcome in several ways, including by implementing thinning activities and by using plant-based insecticides and fungicides such as garlic extract, neem leaves and others. Pest and disease control can also be done by using chemicals such as fungicides with benomyl and sulfur as an active ingredient.
DIVERSITY OF LOCAL TREE SPECIES IN THE REGISTER 31 PROTECTION FOREST AREA KOTA AGUNG UTARA PROTECTION FOREST MANAGEMENT UNIT LAMPUNG PROVINCE
Diversity of local tree species is important in the selection of tree species for reforestation of forest areas. The objectives of this study are to determine the diversity of local tree species, to determine the dominant local tree species and suitable for reforestation in the Register 31 protection forest area, Lampung Province. Data were collected using observational methods and analyzed by descriptive analysis. Furthermore, vegetation analysis is carried out to determine the index of importance value which can then determine the dominance of each local tree population and the diversity of local tree species themselves. The results showed that the most dominant local tree population was durian (Durio zibethinus) with an important value index of 46.5875. The existence of durian trees for all growth phases, including seedlings, poles, saplings, and mature trees, is the most dominant. The local tree species diversity index (H’) was 1.0926. This indicates that the diversity of local tree species in the Register 31 protection forest area is in medium category. Therefore, efforts to enrich local tree species need to be done to maintain the preservation of local tree species in the Register 31 protection forest area, Lampung Province.
