Karakteristik Morfologi Ganoderma Steyaertanum Yang Menyerang Kebun Benih Acacia Mangium Dan Acacia Auriculiformis Di Wonogiri, Jawa Tengah
Acacia mangium and Acacia auriculiformis seed orchards on the island of Java are associated with a different species of Ganoderma. The importance of G. steyaertanum as a pathogen of forest trees has not been previously highlighted. The aim of this study is to look at the characteristics of the G. steyaertanum which attacks two Acacia seed orchads at Wonogiri Central Java. Activities undertaken are to identify the signs of the G. steyaertanum both in the field and in the laboratory. Characterization of fungi is conventionally done by observing the morphology of signs, such as the shape and color of the fruit body, shape and color of mycelium. Morphological characteristic applied in this study has proved to be effective to identify the pathogen. G. steyaertanum was isolated from fruitbodies of affected trees and pathogenicity tests confirmed Koch\u27s postulates. Somatic incompatibility tests demonstrated high genetic variability of the pathogen
Uji Inkompatibilitas Somatik Dan Pertumbuhan Jamur Ganoderma Dari Kebun Benih Generasi Pertama Acacia Auriculiformis Di Wonogiri, Jawa Tengah
Seed orchard A. auriculiformis F1 at Wonogiri, Central Java has attacked by ganoderma caused root rot. To determine the genetic variation, the pattern of spread of ganoderma necessary to somatic incompatibility test and measure the growth. This study used 8 isolates of the fungus ganoderma. Fungi were grown on PDA (Potato dextrose agar), made parental isolates and paired with each other. The results showed that all pairings indicated incompatible reactionsm except self pairings. All self-pairings showed compatible reactions that indicated by miycelia merged on PDA forming a single colony. Incompatible reaction zone is characterized by sparse zone, demarcation line and pigmentation. The results of somatic incompatibility test, ganoderma have different genotypes or it is not a single colony. The result indicates that the distribution of root rot in Seed orchard A. auriculiformis F1 at Wonogiri, Central Java not only occured by root to root contact
Penggunaan Rhizobium Dan Mikoriza Untuk Pertumbuhan Calliandra Calothyrsus Unggul
Calliandra calothyrsus, a rhizobium-associated legume, fixes atmospheric nitrogen by forming root nodules. Rhizobium availability is crucial for Calliandra\u27s growth especially on new sites. Additive or synergic effects of rhizobium and mycorrhiza are found to improve seedling quality. Genetically improved Calliandras require optimum silvicultural practices including rhizobium and mycorrhiza application and differences among families need to be observed. This followed with combination treatment of 5g rhizobium and different mycorrhiza level at and 10g applied to 5 families in 30 X 30 cm polybag. Assessments were for leaf number, height, diameter at 1, 4 and 8 weeks and number of root nodules at 4 and 8 weeks after application. Results show that rhizobium application has no significant effects although it enhances grow, while mycorrhiza application improve leaf number after 14 weeks. Second experiment for 3.5 month seedlings, indicates interaction on family-mycorrhiza level to seedling height and root nodules. Very positive correlations show that more root nodules improved leaf number (r=0.41**), height (r=0.3*) and diameter (r=0.45**) up to planting time. Quite cheap rhizobium and mycorrhiza application is therefore beneficial to optimize the growth of genetically improved Calliandra, although genotype differences may eXist

PENGARUH GAME EDUKATIF TERHADAP KEMAMPUAN LITERASI DAN NUMERASI PESERTA DIDIK TINGKAT SEKOLAH DASAR
Literacy and numeracy are thinking activities that involve learning symbols and the language that expresses them orally or in writing. Data from PISA 2018 shows significant challenges in improving these capabilities in Indonesia. The research method used is an experimental approach by conducting a pretest and posttest. This method is used to study students in a subject using certain learning media. The purpose of making this journal is to find out how much influence education has on the literacy and numeracy skills of elementary school level students. The results of the research show that the use of literacy and numeracy games has a positive impact on students' literacy and numeracy skills. Learners who engage in literacy games show significant improvements in reading ability and text comprehension, while numeracy games help improve basic math skills such as addition, subtraction and problem solving. Apart from that, these games also increase students' learning motivation, making the learning process more fun and interactive.

Kecenderungan Pola Perilaku Agresif dan Eksplosif Remaja (Study Kasus Perilaku Delinkuensi Pelajar di YOGYAKARTA, Perspektif Sosio-religius-edukatif)
This study aims to determine the tendency of aggressive and explosive behavior of adolescents (student delinquency actors) in the Yogyakarta area, which in this case the researchers conducted research at the Sleman Police, Class 1 Child Correctional Center (BAPAS), and the Youth Social Protection and Rehabilitation Center (BPRSR). ) Yogyakarta in Sleman.
This qualitative research in collecting data using in-depth interviews / in-dept interviews, observation/observation, and documentation. The data analysis applies Miles and Huberman's theory, with the following steps: data reduction, data display, verification.
The results showed that the tendency of adolescent aggressive and explosive behavior had elements of revenge and trial and error. The factors causing aggressive and explosive behavior are caused by the underdevelopment of adolescents regarding the development of social cognition, the development of moral reasoning, and the development of a lack of understanding of religion. Besides that, family attention that is not optimal and the negative influence of "gang" are also factors that greatly influence this aggressive and explosive behavior. The solutions that the researchers offer are strengthening education in the family (the power of family), strengthening religious values, developing skills and there is a follow-up on the guidance program provided from the BPRSR at home, in this case, guided by the family
