Abstract

Kabupaten Tuban memiliki tingkat risiko bencana yang tinggi, terutama bencana hidrometeorologi yang dipengaruhi oleh Sungai Bengawan Solo. Jenis bencana yang sering terjadi di antaranya banjir, kekeringan, cuaca ekstrem, dan tanah longsor. Untuk mengurangi dampak bencana, Pemerintah Kabupaten Tuban telah mendorong berbagai upaya mitigasi, termasuk sosialisasi kesiapsiagaan di lingkungan sekolah melalui Program Sekolah Siaga Bencana. Kegiatan sosialisasi di SMKN Palang Tuban bertujuan untuk meningkatkan kesadaran dan kesiapsiagaan siswa, guru, serta staf sekolah dalam menghadapi bencana. Metode yang digunakan dalam kegiatan ini meliputi ceramah, diskusi interaktif, serta pemutaran video simulasi. Hasil kegiatan menunjukkan bahwa mayoritas peserta belum memiliki pemahaman yang memadai tentang mitigasi bencana sebelumnya, sehingga sosialisasi ini menjadi langkah penting dalam mengisi kesenjangan pengetahuan dan keterampilan. Program ini menjadikan seluruh elemen sekolah dapat lebih siap menghadapi situasi darurat, memahami langkah-langkah evakuasi, serta memiliki keterampilan tanggap bencana yang baik. Keberlanjutan sosialisasi dan pelatihan serupa sangat diperlukan untuk menjadikan lingkungan sekolah lebih aman dan tangguh terhadap ancaman bencana.

Abstract

Sampah organik masih menjadi persoalan lingkungan yang nyata di tingkat rumah tangga, terutama di wilayah pedesaan. Menanggapi hal tersebut, program pengabdian ini bertujuan memberdayakan masyarakat Dusun Ngrangin, Desa Sumberpasir, Kecamatan Pakis, Kabupaten Malang untuk mengelola sampah organik secara mandiri melalui inovasi eco enzyme. Kegiatan meliputi sosialisasi, pelatihan teknis, praktik pembuatan, pendampingan, dan evaluasi hasil penerapan di masyarakat. Pendekatan partisipatif diterapkan dengan melibatkan kelompok ibu rumah tangga sebagai penggerak utama perubahan perilaku. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan warga dalam memproduksi serta memanfaatkan eco enzyme untuk kebutuhan sehari-hari. Program ini turut menumbuhkan kesadaran lingkungan, mengurangi volume sampah, dan membuka peluang ekonomi baru berbasis produk ramah lingkungan yang berkelanjutan.

Abstract

This study aims to develop performance improvement strategies for educational institutions based on theEuropean Excellence Model (EEM). The research is conducted at an upper secondary-level educational institution in Malang City using a self-assessment method and a questionnaire constructed based on seven criteria and 32 subcriteria of the EEM. The analysis involves scoring and examining correlations between the Direction and Execution dimensions with the Results dimension, particularly stakeholder perceptions. The institution scores a total of 360 points, identifying several priority areas for improvement, such as organizational culture and performance transformation. The proposed strategies leverage significant internal strengths to address the identified weaknesses

Abstract

Corrosion still remains a serious problem in the application of aluminum alloys, such as Aluminum 6061, which is one of the most widely used aluminum alloys in industries because of its high strength-to-weight ratio. However, the material degrades when exposed to aggressive environments, such as acidic, alkaline, or salty solutions, and the control of corrosion has been achieved with the use of synthetic chemical inhibitors, but the increasing concern of environmental and health risks has shifted attention to more eco-friendly alternatives. The present study aimed at evaluating the efficacy of three vegetable oils (coconut oil, palm oil, and soybean oil) as environmentally friendly corrosion inhibitors for Aluminum 6061, and the alloy coupons were subjected to three different corrosive solutions (hydrochloric acid, sodium hydroxide, and sodium chloride). A quantitative experimental procedure was employed to determine the corrosion rate through the measurement of the weight loss of aluminum coupons prior to and after the immersion, and the results showed that all three oils were able to reduce the corrosion rate when compared to the samples without any inhibitor. Among them, coconut oil gave the best protection, followed by soybean oil and palm oil, because the adsorption of the organic compounds and fatty acids in the oils onto the aluminum surface formed a thin layer that separated the metal and the corrosive environment. Consequently, the results also showed that the use of bio-based oils can be a promising alternative to synthetic corrosion inhibitors in industries that use aluminumbased materials.

Abstract

The growing problem of plastic waste requires innovative and sustainable solutions in terms of processing and recycling. One of the key technologies in the recycling process is the shredder machine, which serves to shred plastic waste into smaller sizes before further processing. However, in practice, industry players, especially at the microscale, often face a dilemma in choosing the optimal shredder machine between performance and cost aspects. This research aims to fill the gap by conducting a comparative analysis of three shredder designs based on price and technical performance criteria. The method used in this research involves quantitative measurements of vary in several key aspects, namely: physical dimensions (body area), frame length, transmission system (gearbox and/or clutch), storage capacity, chopper type, motor specifications (power), speed controller, additional features such as presser, foldability, and total price. Furthermore, the data was analyzed using a simple machine learning approach based on heatmap scoring with the help of Python libraries such as Pandas, Seaborn, and Matplotlib. The analysis results show that the 3rd design provides the best performance. This research contributes to data-driven decision making in shredder machine selection, with an approach that combines technical and economic aspects in an integrated manner. The findings are expected to serve as a reference for the development of efficient and sustainable waste plastic processing technology in the microscale industry sector.

Abstract

Corporate awareness of sustainability has increased significantly alongside growing stakeholder expectations for environmentally responsible practices. The industrial sector’s GDP growth in 2023 was accompanied by higher CO₂ emissions, emphasizing the need for a managerial approach that integrates economic, social, and environmental dimensions. This study develops a strategy map based on the Sustainability Balanced Scorecard (SBSC) by identifying key sustainability performance indicators. Using Exploratory Factor Analysis (EFA), 18 indicators were obtained and grouped into four perspectives: Learning and Growth (3 indicators), Internal Business Processes (8), Stakeholders (3), and Financial (4). The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was then applied to examine causal relationships. Results highlight “green technology innovation,” “energy efficiency and renewable energy practices,” and “green corporate image” as the most influential indicators. The Internal Business Process perspective was identified as the primary driver of sustainability performance. These findings stress the importance of aligning strategies with operational improvements to achieve balanced economic and environmental outcomes.
