Abstract

Livestock population in Indonesia is one of the key indicators supporting national food security, particularly in meeting the demand for animal-based protein. However, the suboptimal utilization of livestock population data for strategic planning remains a challenge in the livestock sector. This study aims to predict livestock population in Indonesia using the Long Short-Term Memory (LSTM) method, a variant of Recurrent Neural Network (RNN) designed for time series data analysis. The livestock population data used in this research was obtained from the Central Statistics Agency (BPS) for the period of 2006 to 2022. The LSTM model was trained using 80% of the data for training and 20% for testing, with evaluation conducted using Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE). The results indicate that the LSTM model can forecast the national livestock population up to 2033 with good accuracy, particularly for livestock such as goats (MAPE 5.47%) and beef cattle (MAPE 5.64%). However, a higher error rate was observed for buffalo (MAPE 16.57%). The predictions indicate a significant growth trend in poultry populations, such as broiler chickens and laying hens. In conclusion, this model can support data-driven decision-making to ensure stable and sustainable animal protein availability, thereby strengthening national food security.

Abstract

This study aims to enhance understanding of water pollution through the use of histology preparations as educational tools for the sub-topic of water pollution in Grade X high school or equivalent. The research employs a descriptive method with a skinative approach. Water pollution is defined as the introduction of organisms, substances, energy, and/or other components into water due to human activities, resulting in a decline in water quality that affects its intended function. Histology preparations serve as a medium to assess the condition of organisms' tissues in rivers. Histology is essential for studying the normal tissue structure of organs or other body parts, addressing both anatomical and physiological aspects. Under a microscope, tissue preparations allow for the study of normal and abnormal tissue structures. Quality preparations must meet two criteria: identification, from organ collection through to observation, requiring expert handling; and cleanliness, assessed by the absence of air bubbles and the overall cleanliness of the preparation.

Abstract

Ongole crossbreed cattle (OCC) is a type of local cattle in Indonesia. Exploration of the main products of local livestock, especially by product, of local Indonesian cattle has never been carried out. The important potential of the by-product is to combat protein malnutrition and food insecurity in many countries. The aim of the study was to explore the proximate composition. The research was carried out using the exploratory laboratory method by taking objects in the field and then analyzing them in the laboratory. Samples were taken from the Animal Slaughterhouse of Lamongan district which originated from 8 Farmers. The variables observed were proximate includes water content, protein, carbohydrate, fat and ash. The proximate composition was dominated by water and protein content with the highest average value obtained from the red offal species. Differences in proximate composition also occur between male OCC and female OCC.

Abstract

Penelitian ini bertujuan untuk meneliti bagaimana lama perendaman dalam ekstrak bawang putih memengaruhi kualitas internal telur. Kualitas intrinsik telur menjadi perhatian penting karena mempengaruhi nilai gizi dan fungsionalitasnya. Bawang putih (Allium sativum) diketahui memiliki senyawa aktif yang berpotensi meningkatkan kualitas telur. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 7 perlakuan dan 5 kali ulangan untuk berbagai lama perendaman dalam ekstrak bawang putih. Analisis data kualitas intrinsik telur, yang meliputi persentase penyusutan bobot telur, HU telur, IPT, dan IKT, dilakukan dengan menggunakan ANOVA satu arah dan uji lanjut Duncan. Penelitian menunjukkan bahwa perendaman telur dalam ekstrak bawang putih selama 25 menit secara signifikan meningkatkan kualitas internal telur. Peningkatan ini diduga terkait dengan aktivitas senyawa aktif dalam bawang putih yang memengaruhi komposisi telur. Penelitian ini menyimpulkan bahwa ekstrak bawang putih berpotensi menjadi larutan perendam alami untuk meningkatkan kualitas telur dengan perendaman selama 25 menit dan penyimpanan pada suhu ruang selama 12 hari. Penelitian ini diharapkan dapat berkontribusi pada pengembangan produk telur yang lebih berkualitas dan bernilai gizi tinggi.   Kata kunci: Bawang putih, Ekstrak bawang putih, Kualitas intrinsik, Lama perendaman, Telur

Abstract

Usaha peternakan ayam petelur di Kabupaten Blitar, khususnya Desa Ponggok, Kecamatan Ponggok, merupakan sentra produksi telur nasional yang krusial bagi ketahanan pangan. Namun, tingginya harga pakan komersial menjadi tantangan utama yang secara signifikan menekan profitabilitas peternak rakyat. Penelitian ini dilakukan untuk mengevaluasi secara komprehensif penampilan produksi dan kualitas telur ayam layer yang mengadopsi pakan selfmix, yaitu praktik pencampuran pakan sendiri, sebagai strategi peternak menekan biaya produksi dan menjamin keberlanjutan usaha. Penelitian menggunakan metode studi kasus dengan pendekatan kualitatif, melibatkan peternak di Desa Ponggok. Peneliti mengumpulkan data melalui observasi langsung, wawancara mendalam, dan dokumentasi. Secara sosial ekonomi, peternak di lokasi studi memiliki rata-rata umur 51–60 tahun dengan tingkat pendidikan rata-rata Sekolah Dasar (SD). Mereka umumnya memelihara layer strain Malindo dengan populasi antara 2.000 hingga 3.000 ekor. Hasil evaluasi menunjukkan bahwa pakan selfmix memberikan penampilan produksi yang memadai: rata-rata konsumsi pakan harian mencapai 120 gram per ekor. Tingkat produksi telur harian (Hen Day Production - HDP) berada pada angka 85%. Namun, pakan selfmix ini tampak memengaruhi kualitas fisik telur; warna cangkang telur sebagian besar (28%) berwarna cokelat, dan tekstur cangkang 91% termasuk mutu 3, yang berarti sedikit kasar. Kesimpulan dari penelitian ini menunjukkan bahwa pakan selfmix berhasil mempertahankan produktivitas yang tinggi (HDP), tetapi peternak perlu melakukan penyesuaian formulasi untuk memperbaiki kualitas dan konsistensi fisik cangkang telur.   Kata kunci: selfmix, konsumsi pakan, hen day production, tekstur cangkang, warna cangkang
