This study aimed to identify tree vegetation types and the structure and composition of trees in two oil palm companies, namely PTPN IV and PTPN III. Identification of forest areas was performed by collecting data from the plantations, and processed tree species data using the quadrat method and calculated using the Shannon-Wiener and Simpson's diversity indices. Results showed that tree species with the highest Importance Value Index is Koompasia excels with a percentage of 92.95%, Shorea sp (56.7%), and Koompasia malaccensis (69.32%). Based on tree height, stratum A (>30 m) dominated in PTPN IV with 840 individual/ha, while in PTPN III-1 stratum B (20-30 m) dominated with 330 individual/ha. There were 600 individual/ha in PTPN IV with diameter class of 10-29 cm, 250 individual/ha with diameter class of 30-49 cm in PTPN III-1, and 220 individual/ha with 30-49 cm diameter in PTPN III-2. The highest Shannon-Wiener diversity index (2.148) was found in PTPN III-2, and the highest Simpson's dominance index (0.187) was found in PTPN IV. An inverted \"J\"-shaped curve indicated that the forest area had a good stand structure, with more small-diameter trees than large-diameter ones. Keywords: High Conservation Value, Importance Value Index, Shannon-Wiener Index, Simpson's Index of Oil Palm.

However, other parts of the rosella plant have not yet been utilized for their antioxidant content and activity. The aim of this research is to compare the profiles of essential oils of parts of the rosella plant (seeds, leaves and flower petals) and their antioxidant activity. This research method begins with the process of extracting essential oils using the water-steam distillation method. Furthermore, the profile of the essential oil is known from the results of yield calculations and characterization using the GC-MS instrument. The antioxidant activity was tested using the DPPH method. The yield of essential oils obtained was 0.0107% for seeds, 0.0087% for leaves and 0.0136% for flower petals. GC-MS characterization shows that the most abundant chemical components contained in the essential oils of seeds, leaves, and flower petals are fatty acid compounds (2-propanoic acid, butanoic acid, hexanoic acid) and esters (neopentyl isobutyrate). The results of the antioxidant activity test showed the IC50 value for each essential oil, namely, seeds: 30.15 μg/ml, leaves: 171.27 μg/ml and flower petals: 126.58 μg/ml. The compound characteristics obtained showed the best results for rosella seed essential oil, this was supported by the fairly high antioxidant activity test results IC50 <50 μg/ml.

A total of 11 managers and 22 operators from 11 farm machinery hire service groups were selected purposively and interviewed to collect field data. The collected data were analyzed using descriptive and quantitative approaches. The results showed that farm machinery hire service groups manage 3 to 6 types of machines, including hand tractors, mini tractors, water pumps, rice transplanters, combine harvesters, and power threshers. The available farm machines are not sufficient to cover the entire area owned by farm machinery hire service groups. Therefore, most machines must work beyond capacity to achieve the target of covering as wide an area as possible. The machinery hire service was profitable for businesses at the farm level in the region.

This study aims to examine the rainfall dynamics leading to landslides in the Bompon Watershed using rainfall threshold analysis. Intensity and duration are selected as parameters to establish the rainfall threshold model. The research findings indicate that long-duration rainfall is the dominant cause of landslides in the Bompon Watershed. High-intensity rainfall can trigger landslides when lasting for more than one day. The established rainfall threshold equation in the Bompon Watershed is I = , where I is intensity and D is duration. The effects of long-duration rainfall include raising the groundwater level, thereby increasing the slope load. The presence of clay in the Bompon Watershed can hinder proper rainwater infiltration. Poorly infiltrated water adds to the slope load and induces slope instability. The calculated rainfall threshold can serve as the basis for early landslide warning systems.

The aim of this study was to improve the biosorption capacity of the biosorbent from agricultural solid waste and its usability for Fe²⁺ removal. The biosorption performance of ECH biochar was optimized through carbonization parameters: temperature, time, and temperature gradient. Response Surface Methodology (RSM) based on multivariate analysis was employed to evaluate the biosorption performance of ECH biochar for Fe²⁺ biosorption. The optimum performance predicted through Box-Behnken design experiment. The optimal combination of the three parameters was 549.37°C, 1.98 h and 21.98°C/min. At the optimal condition the removal efficiency (RE) was predicted to be 107.01% and biosorption capacity (qt) was 5.11 mg/g.
