Abstract
Environmental protection and recovery are the main challenges facing our society today, therefore it is important to know and understand more about pro-ecology behaviour, and what factors influence it. The study was conducted to explain the effect between Instructional Leadership on Student Pro-ecology Behaviour Quantitative method was used to analyse the results. In addition to this, the survey also used through expose fact studies. The sampling was carried out by means of multistage random sampling using the selected 100 students of MAN 6 East Jakarta. From 100 people divided into two groups that gave an assessment of Instructional Leadership below the average of 50 people and above the average of 50 people. Data analysis using t-test to test whether there is influence between Instructional Leadership on Pro-ecology Behaviour. Two opinion instruments have been developed which produce new concepts about Instructional Leadership and pro-ecology behaviour, each of which is 30 items that are valid and realiable. distribution of descriptive and inferential data. The next finding is the influence between Instructional Leadership on the Pro-ecology Behaviour that is significant (t = 1.83> t table = 1.67 α 0.05 df: 48). This shows a high or low level of positivity. The student pro-ecology behaviour was not caused by its assessment of the Melian Instructional Leadership Teacher but because of other factors. Other factors are recommended for further research both internal and external factors. The massive external factor influencing students is probably social media in the era of industrial revolution 4.0.

Published: December 2019

Abstract
Lignin is an essential bio-polymer which is required in the formation of plant cell wall. The degradation of lignin in the nature is a major challenge due to the complexity of its structure. It has been long known that white rot fungi produce ligninolytic enzyme that can degrade lignin efficiently. To identify white rot fungi, screening test was carried out by testing different strains of Basidiomycota using czapek dox agar supplemented with Guaiacol (0,02%). The results showed that two out of thirteen strains of Basidiomycota have ligninolytic activity. In this study, we successfully obtained two strains that have ligninolytic activity. In terms of ligninolytic activity, the potency index of phenol oxidation was higher in SP1 which accounts for 4.30, meanwhile, SP13 only reached potency index of 0.94. This study sheds light on further observation of these strains which potentially can be used for lignocellulose waste treatment especially oil palm empty fruit bunch (OPEFB) to produce valuable product.

Published: December 2019

AbstractLignin is difficult to be decomposed due to its extensive polymerization carbon chain. Previous studies have discovered that ligninolytic enzymes effectively degrade lignin waste. Numerous microorganism such as white rot fungi which belong to basidiomycetes have been taken into account to accelerate the decomposition process of lignin. The aim of this study is to detect the capability of the fungi which were isolated from decayed root and stem of oil palm tree. Qualitative test using guaiacol 0.02 % and quantitative test using agar with supplemented tannic acid test were carried out to observe the ligninolytic capability and potency index of fungal isolates. Out of ten isolates, AKS 5 and PLP 3 were found to be positive strains and grouped to basidiomycetes division. The potency index revealed was higher in AKS 5. Successful of this study could be used as baseline information of potential fungi which are able to degrade lignin waste in the environment.

Abstract
This research was conducted to examine the effect of compost and biochar on the growth and yield of red chili plants. This research is a factorial experiment using Randomized Block Design (RBD), which consists of two factors: compost (0, 10, 20, and 30 tons ha−1) and the type of biochar (bamboo and coconut shell). The interaction between compost and biochar did not have a significant effect on all variables observed in this study. The dosage of compost has a significant effect on fruit length, fresh fruit weight, and fresh weight of roots. The biochar treatment does not have a significant effect on the observed variables except for the number of fruits that have a significant effect. The treatment of various dosage levels did not show any significant difference, but the application of 30 tons ha−1 compost produced the highest fresh fruit weight of 185.35 g or increased by 20.94% when compared to the treatment without compost of 153.26 g. The treatment of this type of biochar only had a significant effect on the number of chili fruit, namely coconut shell biochar which gave the highest value of 17.17 chilies and was significantly different from bamboo-based biochar which produced 15.00 chilies.

Abstract
The quality of fish seed may be decreased as a result of inbreeding that is a marriage between two individuals who have the same genetic trait. Fish seed quality improved with the genetic approach to parent selection and crossbreed. Quality of fish seeds is taking from natural populations are determined by the genetic diversity of a population. Inbreeding can decrease the quality of seed because it can increase the number of homozygosity and decrease the number of heterozygosity. This study aims to determine differences in genetic variation three species of sunu groupers (Plectropomus maculatus, Plectropomus leopardus, and Plectropomus oligacanthus) and know the kinship of the three species of grouper. While the benefits of this research can provide information on genetic diversity in natural coral trout grouper, expected inbreeding can be avoided. Muscle and liver tissue was used as a sample for electrophoresis analysis with twelve kinds of enzymes namely aspartate aminotransferase (AAT), Alcohol dehydrogenase (ADH), Estrase (EST), -Gliserofosfat dehydrogenase (-GPD), Glukofosfat isomerase (GPI), Isocitrate dehydrogenase (IDH), Lactate dehydrogenase (EST), Malic dehydrogenase (MDH), Malic Enzyme (ME), 6-phosphogluconate dehydrogenase (6- PGD), phosphoglucomutase (PGM), and sarcoplasmic enzymes (SP). Three polymorphic loci in Plectropomus oligacanthus species are 6-PGD, GPI-2, and PGM. In Plectropomus maculatus, and Plectropomus leopardus all monomorphic loci. The three polymorphic loci on Plectropomus oligacanthus meet the Hardy-Weinberg balance with X2 value for 6-PGD value is 0.123, GPI-2 is 0.028 and PGM is 0.028. Plectropomus oligacanthus has a polymorphism level of 0.188, the total number of the focusing allele is 1,154, and the average heterozygosity is 0.023. The genetic distance between the sepsis population based on twelve enzymes showed between Plectropomus maculatus, and Plectropomus leopardus had a spacing of 0.134, between Plectropomus leopardus and Plectropomus oligacanthus of genetic distance 0.196 and between Plectropomus maculatus and Plectropomus oligacanthus the genetic distance was 0.200. The larger the genetic distance between the species, the kinship relationship will be farther away. The distant kinship is owned by Plectropomus oligacanthus.
