Abstract

Breeding, feeding and management are important components of the success of a livestock business. Feeding, especially in providing feed with good quantity, quality and continuity, is one of the biggest inputs and challenges in livestock business. Until now, providing feed, especially forage, is still a big challenge in ruminant livestock farming. Mulato grass is a potential alternative forage source because it has good quality, is drought resistant, has high biomass, and is popular with livestock. This community activity (PKM) aims to announce hybrid mulato grass to breeders as a potential forage alternative for ruminants. The object or target in this community service activity is the Bakti Mekar Jaya Forest Farmers Group. The counseling method was used in this activity. The stages of implementing activities consisted of the preparation stage, assessment stage (pre-test), counseling stage and evaluation stage (post test). The results achieved in this extension activity provide benefits for livestock, including: (1) obtaining alternative sources of forage for the livestock being kept; (2) minimizing the risk of a shortage of forage during the dry season; (3) gain knowledge about cultivating hybrid mulato grass. The continued phase of this PPM activity involves observing the development of Mulato hybrid grass to serve as a supplementary feed source.

Abstract

Limbah cair merupakan salah satu penyebab utama pencemaran lingkungan yang dapat mengancam ekosistem, sehingga diperlukan proses pengolahan yang efektif untuk mengurangi dampaknya. Berbagai upaya pengendalian telah dilakukan, dan salah satu alternatif teknologi terbaru adalah penambahan bakteri probiotik ke dalam proses pengolahan. Bakteri probiotik terbukti memiliki kemampuan menurunkan kadar parameter kualitas air limbah, yaitu BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand), dan TSS (Total Suspended Solids). Berdasarkan hasil telaah, ditemukan tiga jenis probiotik yang paling banyak digunakan, yaitu Lactobacillus, Bacillus, dan kombinasi keduanya. Penelitian ini bertujuan untuk mengolah data dan menguji apakah penurunan nilai parameter BOD, COD, dan TSS setelah penambahan bakteri probiotik signifikan secara statistik, mengklasifikasikan persentase penurunan nilai tersebut ke dalam kategori rendah, sedang, dan tinggi, serta menguji perbedaan signifikan dalam penurunan parameter antara ketiga jenis bakteri secara statistik. Metode yang digunakan adalah pengolahan data sekunder yang diperoleh dari jurnal-jurnal relevan, kemudian diproses menggunakan IBM SPSS Statistics. Analisis dilakukan melalui statistik deskriptif, uji normalitas, dan ANOVA. Hasil penelitian menunjukkan bahwa: (1) penambahan bakteri probiotik berhasil menurunkan kadar BOD, COD, dan TSS secara signifikan berdasarkan uji Wilcoxon Rank-Test (p < 0,05), dengan BOD turun dari 2.100 mg/L menjadi 70 mg/L dan COD dari 132 mg/L menjadi 38,1 mg/L. (2) Distribusi nilai persentase penurunan menunjukkan bahwa mayoritas data untuk ketiga parameter (BOD, COD, dan TSS) berada pada kategori sedang, yang mencerminkan efektivitas pengolahan yang baik secara umum. Namun, beberapa data di kategori rendah menunjukkan perlunya optimalisasi, sementara kategori tinggi menunjukkan potensi hasil optimal. (3) Hasil uji ANOVA menunjukkan tidak ada perbedaan signifikan antar jenis bakteri (Lactobacillus, Bacillus, dan kombinasi keduanya) terhadap penurunan BOD, COD, dan TSS (p > 0,05), yang mengindikasikan bahwa pemilihan jenis bakteri tidak mempengaruhi efektivitas, sehingga fokus sebaiknya diarahkan pada pengelolaan proses pengolahan limbah cair.

Abstract

Meningkatnya permintaan daging ayam broiler di Indonesia menekankan pentingnya manajemen kesehatan yang efektif untuk memastikan produktivitas dan kualitas daging yang optimal. Antibiotik atau vaksin yang secara tradisional digunakan untuk mencegah penyakit dan meningkatkan pertumbuhan memiliki risiko residu dalam produk daging, sehingga mendorong eksplorasi alternatif alami. Ekstrak daun binahong (Anredera cordifolia) dikenal memiliki sifat antibakteri, antioksidan, dan meningkatkan kekebalan tubuh, serta menunjukkan potensi sebagai pengganti vaksin alami pada ayam broiler. Penelitian ini bertujuan untuk mengevaluasi dampak ekstrak daun binahong terhadap produktivitas ayam broiler, termasuk bobot badan, rasio konversi pakan (FCR), dan konsumsi pakan. Rancangan Acak Lengkap (RAL) diterapkan pada lima kelompok perlakuan, masing-masing menerima konsentrasi ekstrak binahong yang berbeda atau vaksin konvensional. Hasil menunjukkan bahwa FCR dan konsumsi pakan memiliki perbedaan yang signifikan (P<0,05). Dosis tinggi ekstrak binahong memiliki efek signifikan dalam menurunkan FCR tetapi tidak berbeda dengan kelompok kontrol, sehingga menunjukkan potensinya sebagai alternatif pengganti antibiotik dalam manajemen broiler.

Abstract

Talaga Bodas Nature Park is a volcanic ecotourism area vulnerable to degradation if not managed sustainably. This study aims to develop a sustainable development strategy based on a spatial eco-hydrological approach. This approach integrates NDVI (Normalized Difference Vegetation Index) satellite imagery analysis, erosion estimation using the RUSLE (Revised Universal Soil Loss Equation) method, and strategy formulation using the Analytical Hierarchy Process (AHP). The results show that most areas in Talaga Bodas have moderate to low NDVI values and erosion rates ranging from very light to very severe. The degradation of vegetation and high erosion potential is suspected to be related to uncontrolled tourism activity. AHP-based strategy priorities indicate that zoning regulation, local community involvement, and environmentally-based tourism development are the main strategies for sustainable development in Talaga Bodas. This study highlights the importance of an integrated eco-hydrological approach in managing ecologically vulnerable nature tourism areas.

Abstract

Data security is vital in digital exchange, yet standard Least Significant Bit (LSB) steganography remains vulnerable to unauthorized extraction. This study aims to develop a web-based steganography application combining LSB with Exclusive OR (XOR) encryption to enhance confidentiality. The proposed method involves encrypting secret data using XOR operations before embedding it into the cover image's LSB. The application is built on a web platform for accessibility, and the resulting image quality is evaluated using Mean Square Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The results demonstrate that the system successfully embeds and extracts data intactly. The obtained PSNR values exceed 40 dB, indicating that the stego-images maintain high visual fidelity indistinguishable from the original images, thereby offering a robust solution for secure data transmission.
