Abstract

Indonesia merupakan negara dengan kekayaan alam yang melimpah, hampir segala jenis tumbuhan dapat tumbuh di negara ini. Saat ini, penggunaan bahan herbal telah banyak dikembangkan. Sejalan dengan hal tersebut, taksonomi modern mensyaratkan adanya pendugaan senyawa kimia dalam suatu tumbuhan selain kajian morfologinya. Salah satu familia yang berpotensi sebagai bahan obat dan telah banyak dimanfaatkan adalah Piperaceae. Penelitian ini merupakan penelitian awal yang bertujuan untuk mendeteksi senyawa bahan obat pada dua ekstrak spesies anggota Piperaceae, yakni Piper betle dan Peperomia pellucida. Ekstraksi dilakukan dengan metode maserasi menggunakan pelarut etonol 96%. Pemeriksaan terhadap daun sirih (Piper betle L.) positif mengandung steroid, alkoloid, flavanoid, dan minyak atsiri. Pemeriksaan terhadap daun sirih air (Peperomia pellucida L. Kunth) positif mengandung alkaloid, flavonoid, terpenoid, minyak atsiri, dan tanin. Hasil penelitian ini lebih lanjut dapat digunakan sebagai bahan penelitian dalam bidang taksonomi tumbuhan maupun penemuan bahan obat.

Abstract

This study aims to determine the interaction of rice straw ash application and P fertilizer on the growth of Mucuna bracteata on latosol soil. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Lancang Kuning University located at Jl. Yos Sudarso KM 8 Rumbai, Pekanbaru, Riau with an altitude of 16 m above sea level. This research was conducted from October to December 2024. This research was conducted experimentally using a 4 x 4 factorial Completely Randomized Design (CRD), which consisted of two factors, namely factor P (Rice Straw Ash) and factor T (P Fertilizer), and each had 3 replicates with a total of 48 polybags. The first factor is rice straw ash with four treatment levels, namely P0 (control), P1 (rice straw ash 5 gr/polybag), P2 (straw ash 10 gr/polybag), P3 (straw ash 15 gr/polybag). The second factor is the application of P fertilizer with four treatment levels, namely P0 (control), T1 (P fertilizer 1 gr/polybag), T2 (P fertilizer 2 gr/polybag), T3 (P fertilizer 3 gr/polybag). The research data were analyzed using ANOVA (Analysis of variance) with a real level of 5%. If there is a real difference, it is continued with Duncan's multiple range test or DMRT (Duncan Multiple Range Test) with a real level of 5%. The results of variance showed a significant interaction between the application of rice straw ash and P fertilizer on the growth of Mucuna bracteata on latosol soil. The combination of 15 g of rice straw ash and 2 g of P fertilizer gave the best effect on the growth of the number of internodes of Mucuna bracteata and soil pH in latosol soil.

Abstract

This study aims to determine the influence of compensation and company reputation on Gen Z's decision to choose to work as an assistant in oil palm plantations with work-life balance as a moderation variable. The type of research used is quantitative research with 2 (two) data sources, namely primary data consisting of questionnaire data and secondary data consisting of journals, articles and others. This research consists of 3 (three) variables, namely exogenous variables consisting of compensation (X1) and company reputation (X2), endogenous variables consisting of decisions to choose work (Y) and moderation variables consisting of work life balance (Z). This study was conducted in February – April 2025 on 106 Gen Z respondents who worked as assistants in oil palm plantations. Data analysis using the SmartPLS application with 3 (three) analyses, namely outer model analysis, inner model analysis, and bootstrapping or hypothesis analysis. The results of the study obtained from the analysis of the outer model show that all indicators or items have met the requirements for validity and realism and no multicollinearity between indicators was found. Analysis of the inner model showed that the structural model in the study was proven to be stable without multicollinearity. The bootstrapping analysis or hypothesis shows that compensation and company reputation are proven to have a significant influence on Gen Z's decision to choose to work as an assistant in oil palm plantations, while Work-Life Balance does not play a moderator role in the relationship between these two variables and Gen Z's decision to work as an assistant in oil palm plantations.
