Abstract

Pabrik Kelapa Sawit merupakan salah satu bentuk agroindustri yang berperan penting dalam mengolah Tandan Buah Segar (TBS) menjadi Crude Palm Oil (CPO) dan kernel. Proses produksi Crude Palm Oil (CPO) melibatkan penggunaan suhu dan tekanan tinggi sehingga memiliki potensi bahaya terhadap keselamatan tenaga kerja. Penelitian ini bertujuan untuk menganalisis tingkat risiko kecelakaan kerja pada setiap tahapan proses produksi di PT XYZ dengan menggunakan metode Job Safety Analysis (JSA) Penelitian dilaksanakan pada data diperoleh melalui observasi langsung, wawancara dengan pekerja dan petugas Keselamatan dan Kesehatan Kerja (K3), serta dokumentasi aktivitas di sepuluh stasiun produksi. Analisis dilakukan melalui identifikasi bahaya, penilaian tingkat kemungkinan (likelihood) dan keparahan (severity), serta penentuan tingkat risiko menggunakan matriks JSA.Hasil penelitian menunjukkan bahwa dari 28 aktivitas kerja yang diamati, 11 aktivitas tergolong berisiko rendah, 8 berisiko sedang, dan 9 berisiko tinggi. Bahaya utama meliputi kebisingan, luka bakar akibat uap panas, serta risiko terpeleset di area kerja. Risiko tertinggi terdapat pada stasiun sterilizer, boiler, dan kamar mesin yang beroperasi dengan suhu serta tekanan tinggi. Penerapan Job Safety Analysis (JSA) terbukti efektif dalam mengidentifikasi bahaya, menetapkan prioritas pengendalian, serta meningkatkan kesadaran keselamatan kerja di lingkungan pabrik.

Abstract

The agricultural sector is currently facing an environmental crisis that demands early integration of technology through STEM education. This research aims to develop a learning recommendation model grounded in the SAMR stages as a structured pedagogical framework for integrating the Internet of Things (IoT) into the school environment. The method used is an exploratory qualitative method, which includes data reduction, activity analysis, and qualitative synthesis based on the SAMR model. Concept validation is conducted through a virtual simulation on the Autodesk Tinkercad platform to assess the design's technical and instructional feasibility. The research successfully designed three agricultural IoT prototypes: Smart Irrigation, Smart Seeding Heater, and Soggy Soil Alarm. These prototypes were systematically mapped from the Substitution to Redefinition level. Simulations show that threshold-based automated programming logic can be validated with high precision without the risk of cost or hardware damage. In conclusion, this model successfully bridges the gap between technical tools and meaningful pedagogical transformations. The implementation of virtual simulations has proven to be a strategic solution to enhance computational thinking skills and student engagement in solving real problems in an innovative and fun way.

Abstract

Bioflapon is a construction material developed as an alternative to gypsum, widely used as ceiling panels. As the demand for gypsum continues to increase, other alternatives such as bioflapon need to be evaluated. This study assesses the environmental impacts of pilot-scale bioflapon production using a Life Cycle Assessment approach. The Life Cycle Impact Assessment is conducted using the CML method, focusing on four key impact categories: Global Warming Potential (GWP), acidification, eutrophication, and human toxicity. The bioflapon production consists of two main stages: transportation and processing. The processing includes pulverisation, mixing, and curing. It shows that transportation and curing are the major contributors to environmental impacts. Transportation has the highest contribution to GWP (0.94 kg CO₂ eq), acidification (5.5 × 10⁻³ kg SO₂ eq), and human toxicity (0.41 kg 1,4-dichlorobenzene eq), mainly due to fuel use and emissions. In contrast, eutrophication is dominated by the curing stage, with a value of 2.5 × 10⁻³ kg PO₄³⁻ eq, associated with high energy consumption. These findings indicate that efforts to reduce the environmental impacts of bioflapon production should focus on optimising transportation and improving energy efficiency during the curing process.

Abstract

Industri tahu merupakan salah satu industri rumahan yang menghasilkan limbah cair. Limbah cair industri tahu harus diolah terlebih dahulu sebelum dibuang ke aliran sungai sehingga tidak menyebabkan pencemaran. Adapun tujuan dari penelitian ini adalah untuk mengidentifikasi kandungan limbah cair yang dihasilkan oleh industri tahu serta mengetahui efektivitas penggunaan larutan ‘Bios’ dalam pengolahan limbah cair pada industri tahu. Penelitian ini dilaksanakan pada bulan Juni 2024 dengan metode penelitian eksperimen dan dilakukan analisis secara deskriptif. Dari hasil penelitian didapatkan bahwa penggunaan mikroorganisme yang ada didalam larutan merek ‘Bios’ dapat menurunkan kadar BOD, dengan kadar awal BOD sebesar 1365,6 mg/L menjadi 73,23 mg/L. Selanjutnya kadar awal COD sebesar 7057,2 mg/L menjadi 343,95 mg/L pada limbah cair  tahu yang sudah ditampung didalam kolam. Nilai pH dari 3,71 menjadi 6,3. Hasil penelitian menunjukkan bahwa kadar BOD dan nilai pH limbah cair tahu yang sudah diberi perlakuan menggunakan larutan ‘Bios’ ke kolam penampungan limbah sudah memenuhi ambang batas yang ditetapkan. Kadar kedua parameter tersebut berada di bawah baku mutu yang diatur dalam Peraturan Menteri Lingkungan Hidup No. 05 Tahun 2014 tentang Baku Mutu Air Limbah.
