Abstract

This study aims to determine the effect of the Project Based Learning (PjBL) learning model by using the Inquiry method on the concept comprehension ability of Grade VII students of O Mangunharjo Middle School in 2019/2020. The research method used is pure experimental form. 154 students and the sample is class VII.A as an experimental class and VII.E as a control class. Collecting data in research using tests in the form of a matter of description. Data collected were analyzed using t-test at the significance level α = 0.05. Based on the results of the t-test analysis at a significant level, it can be concluded that there is a significant influence on the Project Based Learning (PjBL) learning model by using the Inquiry method on the ability of concept understanding of seventh grade students of O Mangunharjo Middle School in 2019/2020. The average score of the ability of understanding the concept of the experimental class was 33.13 and the control class was 27.74. Keywords: Project Based Learning Model, Inquiry Method, Concept Understanding

Abstract

Purpose: This study aims to inventory and forecast Greenhouse Gas (GHG) emissions and formulate effective emission reduction strategies in the transportation and industrial sectors of Kendal Regency, with projections extending from 2024 to 2033. Methodology: This study employs Tier 1 and Tier 2 calculation methods based on the IPCC guidelines. Emission projections are modeled under a Business as Usual (BAU) scenario. Mitigation strategies were developed by assessing international best practices and adapting them to the local conditions. Result: By 2033, GHG emissions in the transportation sector are projected to reach 1,596,350 tons of CO? equivalent (CO?eq), while industrial sector emissions are estimated at 111,530.09 tons of CO?eq. The mitigation strategies proposed for the transportation sector could reduce emissions by up to 28%, whereas industrial sector strategies have the potential to cut emissions by up to 76%. Conclusions: Comprehensive mitigation strategies can significantly curb GHG emissions in Kendal Regency. The combination of technological advancements and policy-based interventions offers a robust framework for achieving substantial reductions across both sectors. Limitations: This study is limited by the availability and accuracy of local emission factor data and the assumptions used in BAU projections, which may not fully capture dynamic policy changes or technological breakthroughs. Contribution: This study provides a localized GHG emissions model for Kendal Regency, offering actionable, evidence-based strategies to policymakers and stakeholders to advance regional climate action goals.

Abstract

Tumbuhan Asteraceae dilaporkan mengandung metabolit sekunder tinggi yang aktif sebagai antioksidan. Senyawa antioksidan juga digunakan untuk mencegah penuaan/reaksi glikasi. Penelitian ini bertujuan menentukan aktivitas antioksidan dan antiglikasi 7 tumbuhan Asteraceae. Daun Adenostema lavenia, Ageratum conyzoides, Dichrocephala integrifolia, Galinsoga parvifolia, Synedrella nodiflora, Mikania micrantha, dan Sphagneticola trilobata masing-masing diekstraksi menggunakan air. Ekstrak kemudian ditentukan kandungan total fenol, flavonoid, dan aktivitas antioksidan menggunakan metode 1,1-difenil-2-pikrilhidrazil (DPPH) dan 2,2’-azino-bis(3 ethylbenzothiazoline-6-sulfonic acid (ABTS), serta aktivitas antiglikasi. Ekstrak dengan kadar total fenolik dan flavonoid tertinggi adalah ekstrak M. micrantha. Ekstrak A. lavenia memiliki aktivitas antioksidan terhadap DPPH tertinggi dengan nilai IC50 sebesar 121,82 μg/mL dan A. conyzoides tertinggi terhadap ABTS dengan kapasitas sebesar 4,51 mg trolox ekivalen (TE)/g ekstrak. Aktivitas antiglikasi tertinggi pada ekstrak G. parvifolia sebesar 90,67% yang tidak berbeda nyata dengan ekstrak A. lavenia (87,87%) dan S. trilobata (87,38%). Secara keseluruhan ekstrak A. lavenia dan S. trilobata baik dikembangkan sebagai antioksidan dan antiglikasi.
