Abstract

ABSTRAK: Penelitian ini bertujuan untuk mengetahui kemampuan penyimpanan biomassa karbon atas maupun bawah permukaan tanah dan untuk penyimpanan biomassa karbon pada Sistem agroforestry tanaman kakao (Theobroma cacao, L), dengan luas objek penelitian 1100 ha. Penelitian ini dilaksanakan selama 3 (tiga) bulan. Penelitian ini menggunakan metode allometrik dengan menggunakan rumus W = aDb (Brown 1997) pada lahan agroforestri dan monokultur menggunakan metode destruktif, C organik tanah menggunakan metode Walkey dan Black. Analisa sampel dilakukan di laboratorium Analisa Tanah Fakultas Pertanian Universitas Syiah Kuala dan Laboratorium Balai Pengkajian Teknologi Pertanian Banda Aceh. Hasil penelitian menunjukkan bahwa jumlah cadangan karbon terbesar terdapat pada agroforestri sebesar 66,00 ton/ha, monokultur 32,33 ton/ha Kandungan C organik tanah terbesar terdapat pada agroforestri 7,94 ton/ha, monokultur 6,62 ton/ha. Besarnya cadangan karbon dan kandungan bahan organik tanah pada suatu lahan dipengaruhi oleh tingginya populasi.Kata Kunci : Biomassa karbon, C organik tanah, kakao, agroforestri, Lembah Seulawah

Abstract

This research aims to determine the influence of leadership and work motivation on employee performance at the Peudada Subdistrict Office, Bireuen Regency. The population in this study consists of 44 employees, with a sample selected using purposive sampling. The data analysis method used in this research is multiple linear regression analysis, utilizing SPSS version 25 and Microsoft Excel 2014. Based on the research results, it is found that, partially, the leadership variable has a positive and significant effect on employee performance at the Peudada Subdistrict Office, Bireuen Regency. This is evidenced by the tvalue (3.047) > t-table (1.682) and a significance value of 0.004, which is less than 0.05. The motivation variable also has a positive and significant effect on employee performance at the Peudada Subdistrict Office, Bireuen Regency. This is evidenced by the t-value (2.658) > ttable (1.682) and a significance value of 0.011, which is less than 0.05. Simultaneously, leadership and work motivation have a positive and significant effect on employee performance at the Peudada Subdistrict Office, Bireuen Regency. This is evidenced by the Fvalue (59.959) > F-table (3.23) and a significance value of 0.000, which is far less than α (0.05).

Abstract

This research aims to determine the Influence of STEAM (Science, Technology, Engineering, Art, and Mathematics) Learning Model on the Creativity of 5-6 Year-Old Children. This research is an experimental quantitative study (One group pretest-posttest design). The research population consisted of 15 children. The sample was 15 children aged 5-6 years old in Group B at TK Permata Sunnah Kindergarten, Kota Selatan District, Gorontalo City. Data analysis was conducted using statistical data processing. The research results indicated an increase in the average pre-test score, with an average score of 18.26 and a standard deviation of 3.71. Meanwhile, the post-test data obtained an average score of 31.8 and a standard deviation of 4.76. These results demonstrated a significant increase before and after the treatment. Based on the t-test results at (α) = 0.05, the t-table value was obtained as 2.131, then the t-count was calculated as 8.67. Thus, t-count > t-table; 8.67 > 2.131, meaning that since the tcount > ttable, the H0 was rejected, and the alternative hypothesis (H1) was accepted. Accepting the alternative hypothesis implies that there is an Influence of the STEAM Learning (Science, Technology, Engineering, Art, and Mathematics) on the Creativity of 5-6 Year-Old Children at TK Permata Sunnah Kindergarten, Kota Selatan District, Gorontalo City.

Abstract

The Jantho STIK educational forest is an important habitat for the kedih primate species (Presbytis thomasi), the gray langur (Christatus auratus), and the long-tailed macaque (Macaca fascicularis). The destruction of these primate habitats through forest encroachment is also carried out by the community around the educational forest. The conservation status for these three species is listed as vulnerable in the IUCN and Appendix II in CITES. They are protected animals. Habitat disturbance in the form of forest encroachment is often carried out by the community. This encroachment results in a decline in the quality of primate habitats, due to the loss of food sources and the loss of sleeping trees. In order for the protection of primate species and habitats to take place properly, and the economic value of the community can increase with the presence of primates, as well as to suppress the rate of forest encroachment, it can be done by building ecological barriers in the primate habitat. This ecological barrier is basically made to improve the habitat of wildlife that is experiencing fragmentation. In addition, it is to keep wildlife in their home range, and not to leave their habitat into community agricultural areas. The community service was conducted on August 22-24, 2025, at the STIK education forest in Boeng Jantho village. Community service included socialization of ecological barriers, planting vegetation on ecological barriers, mentoring, evaluation and monitoring. The ecological barrier was made in an area of ​​one hectare and planted with types of vegetation that are not favored by primates (pine, sugar palm and candlenut). The community's enthusiasm was quite high to participate in the socialization and planting. The vegetation developed on ecological barriers can control animals from leaving their natural habitat, so that hunting can be suppressed and forest encroachment can decrease.
