ABSTRACT
This study aimed to determine the school principal's Alaskan system in improving teacher performance. This study uses a qualitative approach with phenomenological methods. This research was conducted at elementary school principals in Lubuklinggau City. The subjects in this study were all people seen by researchers as able to provide data about the elementary school principal's Alaskan system in improving teacher performance. The research subjects included school principals, teacher boards, and staff. Data collection techniques include; observation, interview, and documentation.
In contrast, the data analysis technique used is the data analysis method, according to Miles & Huberman, namely interactive model analysis. Data analysis took place simultaneously, which was carried out simultaneously with the data collection process with a flow of stages: data collection (data collection), data reduction (data reduction), data presentation (data display), and conclusions or verification (conclusion drawing & verifying). The study results show the Alaskan system for leaders in knowing the condition of their subordinates do not have to do blusukan every day because they remember that leaders must carry out other tasks in carrying out their duties. Blusukan can also be carried out suddenly to find out the condition of their subordinates at work, and then also, in the era of the advancement of information technology era leaders can utilize information technology tools to support the activities of carrying out blusukans such as the use of CCTV media to monitor the conditions of their subordinates at work. In conclusion, the school principal blusukan system can utilize information technology tools to support blusukan implementation activities, such as the use of CCTV media to monitor the conditions of his subordinates at work

This study aims to determine the effectiveness of Jatropha plant in accumulating metal contaminants in the form of lead (Pb) in coal solvent. The method used is descriptive quantitative analysis method. The results showed that the metal content of lead (Pb) in the soil before and after treatment changed from 25.8904 mg/kg to 14.3991 mg/kg. In conclusion, Jatropha curcas (Jatropha curcas) is able to accumulate the presence of metal contaminants in the form of lead (Pb) because the metal concentration in the soil decreases after the acclimatization period, so this plant species is very suitable to be used as a phytoremediation effort to reduce contaminants in heavy metal polluted soil.

This study aims to determine the best treatment of spacing, pruning, and their interactions on vegetative growth in the black soybean cultivar Glycine max L. The method used was factorial RAK with 3 replications: 1st factor of Detam 3 (K1) and Detam 4 (K2) cultivars; 2nd factor, J1 = 20 cm 20 cm and J2 = 20 cm 40 cm; 3rd factor, -3 trimming (P1) and no trimming (P2). Parameters observed were plant height, number of active root nodules, number of leaves, number of production branches, and chlorophyll content. The results showed that the treatment of J1 spacing (20 cm x 20 cm) had a significant effect on all research parameters, namely plant height, number of production branches, number of leaves, chlorophyll content, and number of root nodules. Treatment P1 (pruning) had a significant effect on plant height and chlorophyll content; P2 (no pruning) had a significant effect on the number of production branches, number of leaves, and number of root nodules. Treatment of cultivar type K1 (Cultivar Detam 3) had a significant effect on all types of parameters. It can be concluded from this study that there is no interaction between planting distance, pruning, and cultivar type on vegetative growth in black soybeans (Glycine max L).

This study aims to determine the ability of lipolytic bacteria to degrade lipids by obtaining isolates of lipolytic bacteria in palm oil industrial wastewater. By testing the ability of the lipolytic index, the research method used is a description method with bacterial isolation techniques using NA media (Nutrient Agar) and selective media for lipolytic agar. The results showed that there were 10 isolates of lipolytic bacteria with morphological and biochemical characteristics indicating three bacterial genera, namely, the genera Bacillus, Pseudomonas, and Klebsiella. Data analysis showed that 10 isolates of lipolytic bacteria had the potential to degrade lipids; the highest lipolytic activity index value of the isolates was found in isolate BL1 at 0.48 mm, and the lowest lipolytic index was found in isolate BL9 at 0.16 mm. In conclusion, isolating and identifying lipolytic bacteria in palm oil wastewater is one way to reduce environmental pollution that damages existing ecosystems in the environment.

Published: September 2023

This study aims to describe the effect of the verticulture system and spacing on the vegetative growth of two cultivars of black soybean (Gylcine max L.). This study used a factorial randomized block design (RBD) with two treatment factors and 4 replications, namely F1= cultivar (P) consisting of two levels, namely P1= soybean cultivar Detam 1 and P2 = soybean cultivar Detam 4 Prida. F2= plant spacing consists of two levels, namely J1= 20 x 10 cm and J2= 20 x 20 cm. The parameters used were plant height, leaf area index, chlorophyll a, b and total content, relative growth rate, net assimilation rate, and number of root nodules. The results obtained from this study plant spacing had a significant effect on several parameters with the best level, namely J2= 20 x 20 cm and soybean cultivars with P1= detam 1 level had a significant effect on plant height parameters. But the plant spacing and the two soybean cultivars (Gylcine max L.) did not have any interaction in each parameter. It can be concluded that the regulation of planting distances and two soybean cultivars has a significant effect on several parameters such as plant height, chlorophyll content tests a, b and total as well as measuring relative growth rates.
