Abstract

Mushola Nurul Iman di Desa Naga Timbul, Kecamatan Tanjung Morawa, Kabupaten Deli Serdang merupakan sarana ibadah yang berperan penting sebagai pusat kegiatan keagamaan masyarakat. Meskipun Desa Naga Timbul telah memperoleh akses listrik PLN sejak tahun 2021, fasilitas pendukung di mushola masih belum memadai. Kondisi eksisting menunjukkan belum tersedianya instalasi pipa air bersih menuju WC sehingga jamaah harus mengambil air menggunakan ember, penerangan hanya tersedia di ruang utama sedangkan area tempat wudu, WC, dan selasar masih minim pencahayaan, serta belum tersedia kipas angin yang menyebabkan ruang ibadah terasa panas dan kurang nyaman. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kenyamanan, keamanan, dan kualitas fasilitas ibadah melalui revitalisasi sarana dan prasarana Mushola Nurul Iman. Metode pelaksanaan meliputi survei dan identifikasi kebutuhan mitra, perencanaan teknis, pengadaan material, pemasangan instalasi pipa air bersih menuju WC, penambahan instalasi penerangan, pemasangan kipas angin, pengujian fungsi seluruh instalasi, serta pendampingan kepada pengurus mushola mengenai pengoperasian dan pemeliharaan fasilitas. Hasil kegiatan menunjukkan bahwa instalasi air bersih ke WC telah berfungsi dengan baik, sistem penerangan pada area mushola menjadi lebih memadai, sirkulasi udara di dalam ruang ibadah meningkat dengan pemasangan kipas angin, serta seluruh fasilitas yang dipasang beroperasi sesuai fungsinya. Perbaikan tersebut meningkatkan kenyamanan jamaah dalam melaksanakan ibadah sekaligus mendukung keberlanjutan pengelolaan fasilitas Mushola Nurul Iman.

Abstract

Ketersediaan hijauan makanan ternak (forages) yang berkualitas merupakan faktor krusial dalam mendukung produktivitas dan keberlanjutan usaha peternakan, khususnya pada peternakan kambing Ettawa di Dusun I Tambak Rejo, Desa Amplas, Kecamatan Percut Sei Tuan. Bapak Sutejo, sebagai peternak mitra, telah menjalankan usaha ini sejak tahun 2001 dengan fokus pada produksi susu kambing. Populasi ternak saat ini mencapai 43 ekor, turun dari jumlah tertinggi sebelumnya sebanyak 79 ekor, dengan produksi susu yang juga mengalami penurunan dari 55 menjadi 15 bungkus per hari. Penurunan tersebut berkaitan erat dengan ketersediaan dan kualitas pakan segar. Saat ini, sumber pakan masih bergantung pada rumput alami dan hijauan lokal seperti batang jagung dan daun ubi, namun belum dikelola secara optimal. Banyak rumput terbuang karena tidak termakan sempurna oleh ternak. Oleh karena itu, diperlukan intervensi melalui penyediaan mesin pencacah rumput dan teknologi fermentasi pakan, guna meningkatkan efisiensi konsumsi pakan dan memastikan ketersediaan cadangan saat musim kemarau. Penguatan aspek manajemen kandang dan pembentukan kelompok peternak juga menjadi strategi penting untuk meningkatkan skala dan daya saing usaha peternakan rakyat di wilayah ini. Ditawarkan solusi berupa pengadaan alat bantu berupa mesin pencacah rumput dan pelatihan penggunaan dan perawatan mesin. Metode pelaksanaan pengabdian dengan rancang bangun mesin pencacah rumput, pelatihan dan pendampingan kepada mitra peternak.

Abstract

Budidaya ikan lele merupakan salah satu sektor perikanan air tawar yang memiliki nilai ekonomi tinggi dan berkontribusi terhadap ketahanan pangan nasional. Namun, produktivitas budidaya masih menghadapi kendala berupa tingginya tingkat mortalitas ikan yang berdasarkan data Badan Pusat Statistik dapat mencapai 60%. Kondisi tersebut umumnya disebabkan oleh menurunnya kualitas air kolam akibat fluktuasi parameter lingkungan, seperti suhu dan derajat keasaman (pH), yang tidak terpantau secara berkelanjutan sehingga menghambat pengambilan keputusan secara cepat oleh peternak. Penelitian ini bertujuan merancang, membangun, dan mengimplementasikan sistem monitoring kualitas air kolam berbasis Internet of Things (IoT) dengan arsitektur komunikasi Device-to-Cloud sebagai solusi preventif dalam mendukung pengelolaan budidaya ikan lele secara lebih efektif dan efisien. Pengembangan sistem mengacu pada model Prototype Pressman yang meliputi tahapan komunikasi kebutuhan pengguna, perencanaan, pemodelan, konstruksi prototipe, serta pengujian dan evaluasi secara iteratif hingga diperoleh sistem yang sesuai dengan kebutuhan pengguna. Sistem memanfaatkan sensor DS18B20 untuk mengukur suhu air dan sensor pH untuk memantau tingkat keasaman, sedangkan data hasil pengukuran dikirimkan secara real-time ke platform berbasis cloud dan ditampilkan pada perangkat bergerak sehingga dapat diakses kapan saja dan di mana saja oleh peternak. Hasil pengujian lapangan selama sepuluh hari menunjukkan bahwa sistem mampu beroperasi secara stabil dengan kemampuan menampilkan data monitoring secara real-time. Hasil validasi instrumen menunjukkan bahwa sensor suhu DS18B20 memiliki tingkat akurasi sebesar 99,88% dengan nilai galat 0,12%, sedangkan sensor pH mencapai tingkat akurasi rata-rata 99,71% dengan nilai galat 0,14%. Tingginya tingkat akurasi kedua sensor menunjukkan bahwa sistem memiliki keandalan yang sangat baik dalam memantau perubahan kualitas air kolam. Dengan demikian, sistem monitoring berbasis IoT yang dikembangkan dinilai layak diterapkan sebagai perangkat pendukung pengambilan keputusan dalam pengelolaan budidaya ikan lele, sehingga berpotensi mengurangi tingkat mortalitas, meningkatkan produktivitas budidaya, serta mendorong penerapan teknologi digital pada sektor akuakultur.
