Abstract

Asam humat adalah bahan organik yang meningkatkan aerasi tanah dan retensi air. Asam humat memiliki luas permukaan yang lebih besar dan kendaraan yang dapat menyerap dan menahan air tujuh kali lebih banyak daripada pasir. Asam humat kini digunakan sebagai bahan tambahan pupuk yang dapat meningkatkan penggunaan pupuk dan meningkatkan hasil panen. Memasok asam humat efektif dalam memerangi penyakit. Penelitian ini dilaksanakan di di Kecamatan Trowulan, Kabupaten Mojokerto dengan melakukan pengamatan secara berkala setiap 10 hari sekali dengan melakukan pengamatan berupa; tinggi tanaman, jumlah daun, jumlah cabang jumlah malai, persentase serangan OPT, Analisa Usaha Tani dan data pada saat panen. Hasil penelitian menyatakan bahwa adanya asam humat yang mencapai ketinggian tanaman bayam, yang mengandung baik asam humat maupun karbohidrat, meningkatkan kandungan karbohidrat pada tanaman bayam, sehingga tanaman bayam memiliki cadangan hara yang cepat berkembang tunas baru.

Abstract

Chromium (Cr) metal is a pollutant caused by industrial waste disposal and agricultural activities. An alternative solution to managing chromium pollution in an environmentally friendly manner is phytoremediation using Fimbristylis globulosa combined with Agrobacterium sp. This research aims to measure 1). the ability of Fimbristylis globulosa combined with Agrobacterium sp. to absorb Cr metal; and 2). the value of the Cr metal bioconcentration factor (BCF) absorbed by Fimbristylis globulosa combined with Agrobacterium sp. This research used factorial design 2x5 with randomized design. Chromium metal analysis using atomic absorption spectrophotometer. Data were analyzed using BCF test. The results showed: 1) the highest Cr metal absorption in the treatment of Fimbristylis globulosa-Agrobacterium sp.-Cr metal content of 30 ppm (T2V3) root: 7,987 ppm and shoot: 15,649 ppm; 2) the highest value of Cr metal BCF in the treatment of Fimbristylis globulosa-Agrobacterium sp.-Cr metal content of 30 ppm (T2V3) root is 0.266 and Fimbristylis globulosa-Agrobacterium sp.-Cr metal content 10 ppm (T2V1) shoot is 0.675. Conclusions of this research are: 1) Fimbristylis globulosa combined with Agrobacterium sp. has a higher Cr metal absorption ability than without a combination of both; and 2) Fimbristylis globulosa combined with Agrobacterium sp. has a higher value of the Cr metal BCF than without a combination of both.

Abstract

Produksi Jagung Dalam Negeri Belum Mampu Memenuhi Kebutuhan, Sehingga Kedepan Jagung Memiliki Potensi Untuk Dikembangkan Sebagai Sumber Bahan Pakan, Pangan Dan Industri Lainnya. Upaya Peningkatan Produksi Jagung Akan Terus Digulirkan. Tahapan Pasca Panen Merupakan Salah Satu Faktor Vital Yang Cukup Berpengaruh Terhadap Produksi Peningkatan Produksi Jagung Perlu Disertai Dengan Upaya Perbaikan Proses Pasca Panen. Penanganan Pasca Panen Dimaksudkan Untuk Mengusahakan Agar Produk Tidak Mengalami Susut, Baik Itu Susut Mutu Dan Susur Bobot, Sehingga Kualitas Jagung Yang Dihasilkan Oleh Petani Memperolah Harga Yang Layak. Hasil Penelitian Dalam Penelitian Ini Adalah Jagung Biasanya Dipanen Pada Umur Sekitar 4 Sampai 4,5 Bulan. Kegiatan Pasca Panen Terdiri Dari Sejumlah Tahapan Dimulai Dari Panen, Pengupasan, Pengeringan, Pemipilan, Penyimpanan Dan Pengangkutan. Penanganan Pasca Panen Komoditas Jagung Di Beberapa Kecamatan Di Indonesia Masih Belum Optimal, Belum Banyaknya Pengetahuan, Teknologi Dan Ketrampilan Masyarakat Daerah Tentang Jagung. Dalam Hal Penanganan Pasca Panen Jagung Juga Mesin Terbatas.

Abstract

This study aims to analyze the effectiveness of molasses produced from a mixture of sugarcane juice and brown sugar in terms of chemical composition, antioxidant activity, and its potential as a fermentation substrate for ethanol and lactic acid. The study used a literature review approach by reviewing relevant scientific articles, proceedings, and academic books from the last five to ten years. These sources were selected based on the clarity of the method, the relationship to molasses characteristics, and its use in functional foods and the bioindustry. The results of the study indicate that sugarcane molasses is rich in phenolics, flavonoids, and melanoidins with high antioxidant capacity, while brown sugar also has strong antioxidant activity and contributes minerals and Maillard compounds that play a role in redox activity. Sugarcane molasses has been proven effective as a fermentation substrate for the production of ethanol and lactic acid with competitive process performance and relatively low carbon source costs. Theoretically, molasses from a mixture of sugarcane juice and brown sugar has the potential to produce a sweet matrix with a high density of bioactive compounds and favorable fermentative characteristics. However, specific experimental data on the mixed molasses is still limited, so further research is needed to verify its chemical profile, actual antioxidant activity, safety, and fermentation performance.

Abstract

Pengolahan bawang merah pasca panen adalah salah satu bidang yang membutuhkan perhatian khusus, terutama karena proses pengupasannya masih dilakukan secara manual oleh usaha kecil dan rumah tangga pada KWT Mekar Sari Nganjuk. Pekerja memiliki risiko mengalami keluhan muskuloskeletal karena postur kerja mereka yang tidak ergonomis. Kegiatan pengabdian ini bertujuan memberikan solusi perbaikan metode kerja berdasarkan prioritas ergonomic dalam proses pengupasan bawang merah untuk meningkatkan efisiensi kerja, kenyamanan kerja, dan keselamatan kerja pekerja. Metode yang digunakan pendekatan edukatif dan partisipatif melalui sosialisasi, dan pelatihan penerapan prinsip ergonomi. Hasil pengabdian menunjukkan bahwa prioritas usulan perbaikan kepada KWT disesuaikan dengan kemampuan dengan perkiraan biaya meliputi: (1) penggunaan kursi bersandar dan meja kerja, (2) penataan area sistem stasiun kerja duduk, (3) penerapan program istirahat dan stretching setiap jam kerja. Kegiatan ini memberikan manfaat terutama menjadi model penerapan ergonomi sederhana bagi usaha kecil dalam peningkatana produktivitas dan kesehatan keselamatan kerja.

Abstract

The increasing generation of agro-industrial food processing waste presents environmental challenges while offering opportunities for resource recovery within a circular bioeconomy. This study evaluated the conversion of food processing cake waste from PT Belfoods Indonesia (Nganjuk, Indonesia) into organic fertilizer using a double-molasses biofermentation system with beneficial microorganisms activated by fresh sugarcane juice and palm sugar. A longitudinal experimental approach was applied through three stages: raw material characterization, biofermentation, and mature fertilizer production. Physicochemical properties were analyzed using standardized laboratory methods, while fertilizer performance was assessed through a 14-day field bioassay. Biofermentation significantly improved fertilizer quality, increasing total nitrogen from 0.17% to 0.69% and available phosphorus (P₂O₅) from 60.47 mg kg⁻¹ to 5,264.77 mg kg⁻¹. The final product contained no detectable hazardous heavy metals, including arsenic, cadmium, mercury, lead, and tin, confirming its environmental safety. Field observations showed improved plant growth, characterized by darker green leaves, greater foliage density, and stronger stems after fertilizer application. These findings demonstrate that the proposed double-molasses biofermentation system effectively transforms food processing cake waste into a safe, nutrient-enriched organic fertilizer with promising agronomic potential, supporting sustainable waste valorization and circular agricultural production.
