Abstract

Soil macrofauna are important bioindicators of soil fertility. Soil fertility is strongly influenced by soil conditions, which affect the presence and density of macrofauna populations through the decomposition of organic matter. This study aimed to determine the diversity of soil macrofauna across different habitat types in the Batutegi Protection Forest (BPF), Tanggamus, Lampung. The methods used included pitfall traps, point counts, and hand sorting. Three plots were set up, each with three pitfall traps. The point count method involved walking a 100-meter transect with 10 stopping points, each observed for 10 minutes. The hand sorting method was conducted in three 25 × 25 cm plots at a depth of 20 cm. The soil macrofauna diversity indices obtained using the pitfall trap method were as follows: river border (H'=2.9), shrub area (H'=3.1), and forest interior (H'=3.1). Using the point count method, the diversity indices were: river border (H'=3.5), shrub area (H'=2.8), and forest interior (H'=3.3). The diversity indices from the hand sorting method were: river border (H'=2.7), shrub area (H'=2.4), and forest interior (H'=1.8).

Abstract

Way Kambas National Park (TNWK) in Lampung Province is experiencing prolonged drought, prompting the need for artificial water sources for wildlife. This study evaluated natural water conditions and compared three water provision methods. Conducted in collaboration with the Sumatran Tiger Conservation Foundation (October–December 2023), the research covered SPTN I Way Kanan (Rawa Bunder and Way Kanan Resorts) and SPTN III Kuala Penet (Margahayu Resort) in TNWK. Parameters included salinity measurements of natural water and testing plastic tubs, tarpaulin ponds, and their combination at 12 sites, monitored using trap cameras.The results showed that the Way Kanan River, the only remaining natural water source, had high salinity (13–15‰). Wildlife activity was higher at plastic tubs than at tarpaulin ponds, based on trap camera data.  Key words: wildlife water developments, drought, Way Kambas National Park.

Abstract

Way Umpu River, located in Way Kanan Regency, Lampung Province, is widely used by the local community and the waste products are ultimately disposed of into the river. This can cause a decrease in river water quality which can cause changes in the balance of the ecosystem, both biotic and abiotic. One of the organisms that can be used as a bioindicator is macrozoobenthos. This research aims to determine the diversity of macrozoobenthos as a bioindicator of water pollution quality. The method used was a survey method and sampling using Ekmen Grab at 6 sampling stations. Samples were taken 3 times in the left, middle and right bank areas of the river. Apart from that, water analysis was carried out in the form of physical parameters (temperature and TSS) and chemical parameters (pH, DO, COD, BOD). The data was then analyzed using the Diversity Index. The research results found 14 types of macrozoobenthos consisting of 5 phylum, namely Arthopoda, Mollusca, Porifera, Ciliophora, and Annelida. From the results of the analysis of the macrozoobenthos diversity index at station IV, it has a value of 0.56 ind/m2, which states that the location is heavily polluted. Physical and chemical factors show a significant correlation with macrozoobenthos diversity.

Abstract

The Faculty of Mathematics and Natural Sciences (FMIPA) as one of the faculties at the University of Lampung has many trees that produce organic waste in the form of leaf litter every day, and this is very potential to be used as a substrate for compost. Compost is the final substance of a fermentation process of piles of waste/plant litter and sometimes also includes animal carcasses. In the open, compost can occur on its own, through natural processes. However, the process takes a long time while the need for fertile soil is urgent. Therefore, the process needs to be accelerated with the help of microorganisms. This community service activity is a form of application of science and technology by inducing leaf debris as compost material with saprotroph fungi inoculum. Saprotroph fungi isolates are very potential to be developed into composting inoculum in making organic fertilizers. Compost induced with this fungal inoculum is expected to produce organic fertilizer relatively quickly and contain high plant nutrients. The results of the Community Service showed quite good results, namely an increase of about 88.4% from the initial understanding. This is quite interesting because the initial understanding of compost and inoculum was relatively low at 25.04%. After the explanation given by the Community Service team, it was able to be understood by the target audience well so that their understanding increased to 63, 6%.

Abstract

As an additional nutrient that can enhance plant fertility, fertilizer is a crucial factor in achieving plant productivity. One type of fertilizer that is good to use is organic fertilizer, which is derived from the fermentation or composting of plant and animal residues. Organic fertilizer can be made at home using household organic waste. In Pisang Baru Village, a considerable amount of banana stem waste is often discarded by the community. Based on this condition, this activity is aimed at providing training and understanding to the community of Pisang Baru Village regarding liquid organic fertilizer from banana stem waste. The activity is conducted through presentations, hands-on practice, and discussions with participants who are members of farmer groups. The results of this activity indicate that farmers who participated in the training show a high level of interest in using organic fertilizer on their agricultural land, which has the potential to realize sustainable agriculture through the use of organic fertilizers.

Abstract

Bukit Barisan Selatan National Park (BBSNP) is the third largest protected area in Sumatra.  Unfortunately, the area is invaded by Merremia peltata which occupied  about  7 000 ha. The aims of this study was to determine the ecological impacts of  M. peltata on plant biodiversity at BBSNP. Three locations were selected for vegetation analysis and M.peltata invasion assessment on the vegetation composition in BBSNP, i.e. the primary forest representing undisturbed area, secondary forest representing burned area, and invaded forest representing forest invaded by M. peltata. Three line transects  were constructed at each locations along1 km, and  the nested sampling plots were constructed every 100 m with the following quadrants : 20 m x 20 m for trees, 10 m  x 10 m for poles, 5 m  x 5 m for sapling, and 2 m x 2 m for seedling. The data collected were invasions of M. peltata, trees species, and diameter of the trees.  Invaded forest has lower diversity index (1.90)  than the other two. This caused by the invasion of M. peltata as the percentage of coverage in the invaded forest reached 44% compared to secondary and the primary forest which were  27.11% and 1.00%. It is evidenced by the correlation between the percentage of coverage M. peltata and diversity index (-0.988).

Abstract

Some areas in Bukit Barisan Selatan National Park have serious environmental problems related to the invasion of Merremia peltata (Family: Convolvulaceae). This study investigated abiotic factors influencing the invasion. The research compared abiotic conditions in three forest locations with different invasion levels: severe, moderate, and mild. Measured abiotic factors included percentage of tree canopy cover, microclimate variables (temperature and humidity), elevation above sea level, and the physical and chemical properties of the soil surface. In this study, canopy cover was categorized as an abiotic factor because it affects the amount of light reaching the forest floor. A post-hoc Duncan's Multiple Range Test (DMRT) was performed to determine significant differences (p < 0.05) among abiotic variables. Additionally, correlation analysis and multiple linear regression were conducted to evaluate the relationships between abiotic factors and the level of M. peltata invasion. Multiple regression analysis showed that canopy cover significantly (p < 0.05) affected the invasion. Based on the generated model, a 1% increase in canopy cover would decrease the M. peltata invasion by approximately 2.8%. Soil nutrient analysis through multiple linear regression revealed that the C/N ratio, and concentrations of P₂O₅, Ca, Mg, and Na significantly (p < 0.05) influenced invasion level. An increase in C/N ratio and concentrations of P₂O₅ and Ca were correlated with a reduction in invasion, whereas increases in Mg and Na concentrations were associated with higher invasion levels. Overall, the invasion of Merremia peltata in Bukit Barisan Selatan National Park was influenced by an open forest canopy and was associated with high concentrations of Na and Mg in the soil of invaded areas.
