Abstract

Mayoritas masyarakat di Desa Pemberwarno bermata pencaharian sebagai petani, baik sebagai petani jagung, ubi kayu, dan padi. Harga panen yang tidak stabil cenderung membuat masyarakat kecewa karena tidak jarang memenuhi harga yang tidak sesuai ekspektasi. Oleh karena itu, masyarakat harus jeli dalam mengantisipasi hasil panen yang tidak memuaskan salah satunya dengan mengolah limbah tanaman untuk dimanfaatkan menjadi penghasilan tambahan. Limbah jagung misalnya dapat dimanfaatkan sebagai media pembuatan jamur janggel. Jagung biasanya dijual setelah melalui proses penggilingan hingga biji jagung terlepas dari tongkolnya. Setelah itu tongkol jagung atau biasa disebut janggel digunakan sebagai bahan bakar untuk memasak secara tradisional dan dibuang begitu saja tanpa ada gunanya. Oleh karena itu tujuan pengabdian ini adalah memberikan pembinaan kepada masyarakat agar memperoleh nilai tambah pendapatan melalui pemanfaatan tongkol jagung sebagai media pembuatan jamur janggel. Hasil yang didapat menunjukkan peningkatan penjualan jamur jejel yang cukup besar dengan harga perkilogram mencapai 35 ribu hingga 40 ribu rupiah. Untuk pemasarannya masih sebatas pasar tradisional.Training on the Utilization of Corn Cobs as Media for Making Janggel Mushrooms in the village ofgantiwarno, East LampungAbstractMajority of the people in Pemberwarno village livelihood as farmers, both as corn, cassava, and rice farmers. Unstable harvest prices tend to make people disappointed because it is not uncommon to meet prices that do not match expectations. Therefore, the public must be smart in anticipating unsatisfactory crops one of them by treating crop waste to be utilized to be additional income. Corn waste, for example, can be used as a medium for making mushroom janggel. Corn is usually sold after going through the milling process until the seeds of corn are separated from the cobs. After that corncobs or commonly called janggel used as fuel for cooking traditionally and just thrown away without any use. Therefore, the purpose of this dedication is to provide training to the public in order to obtain value-added income through the utilization of corncob as a medium for making mushroom janggel. The results obtained indicate a considerable increase of sales of mushrooms jejel with perkilogram prices reached 35 thousand to 40 thousand dollars. For marketing is still limited to traditional markets.

Abstract

This activity was carried out through training for teachers at UPTD SDN 4 Pakuan Aji. The aim was to assist teachers in creating more engaging learning media that align with the Merdeka Curriculum. The implementation method consisted of four stages: warming up, presentation, training, and closing. The subjects were 13 teachers from UPTD SDN 4 Pakuan Aji. This activity was motivated by the need for teachers to gain knowledge about literacy-numeracy-based and digital literacy-numeracy-based learning models, as the Merdeka Belajar program from the Ministry of Education and Culture has not yet been fully absorbed by the teachers.The results showed an increase in enthusiasm and changes in participants' behavior at each stage of the activity, as well as improved understanding of literacy and numeracy-based learning models. This was evident from a brief teaching demonstration conducted by one of the teachers from UPTD SDN 4 Pakuan Aji.

Abstract

Purpose: This study investigates the impact of application-based problems in systems of linear equations through the Project-Based Learning (PjBL) model on students’ critical thinking abilities. Critical thinking is a vital 21st-century skill, yet Indonesian students often demonstrate low proficiency in this area, particularly in mathematical contexts such as linear algebra. Method: A mixed-methods design was employed, combining qualitative and quantitative approaches. The participants were 28 students from STKIP Kusuma Negara, selected using purposive sampling. Data were collected through pre-tests and post-tests involving application problems, including chemical reaction equations and polynomial interpolation. Additionally, six students were selected for in-depth qualitative analysis based on their initial critical thinking levels. The data were analyzed using descriptive methods and N-gain calculations. Findings: Findings showed a significant improvement in students’ critical thinking skills after the intervention. The post-test average score increased to 81.93 with an N-gain score of 0.61, categorized as moderate. High-achieving students met all critical thinking indicators, while those with moderate or low abilities showed partial improvement. The use of structured learning worksheets (LKM) and real-world mathematical tasks within the PjBL framework effectively facilitated students’ ability to interpret, analyze, evaluate, and draw conclusions. Significance: This study demonstrates the potential of the PjBL model in fostering critical thinking, especially when combined with contextualized algebra problems. These findings offer practical implications for mathematics instruction, particularly in preparing future educators to promote analytical and reflective learning practices.

Abstract

This research aims to develop valid and reliable measuring tool for students' algebraic abilities that can be used in schools and the general public. The research follows a structured test development design, including stages such as preparing test specifications and items, field testing, revising items, and test development. The questions are aligned with the 2013 curriculum syllabus, ensuring relevance to educational standards. The test was given to 662 junior high school students in Kendari City, Indonesia, and their responses were analyzed using the item response theory (IRT) model with two logistic parameters: item difficulty level and item discriminatory power. The BILOG MG program was employed to estimate item and ability parameters. Before conducting item analysis with IRT, essential assumption tests were conducted, including unidimensional and model fit tests. The results of the development process, based on item analysis using BILOG MG, yielded 15 items covering various aspects of algebraic abilities. These items were derived from indicators such as recognizing algebraic forms, identifying elements within these forms, performing addition, subtraction, multiplication, and division operations on algebraic forms, presenting and solving real-world problems in algebraic contexts, and addressing contextual problems involving algebraic operations. The items demonstrated good fit with the model and exhibited an appropriate level of item difficulty and discriminatory power, making them suitable for use as a reliable assessment tool. Consequently, these developed tests are deemed effective for measuring students' foundational algebraic abilities.
