Abstract

Abstrak Selenium (Se) merupakan mikro mineral penting yang sering ditambahkan dalam pakan ternak domba untuk meningkatkan efisiensi reproduksi. Selenium organik memiliki keunggulan karena dapat tersimpan dalam jaringan tubuh sehingga berperan lebih optimal dalam mendukung produktivitas ternak. Selain kandungan nutrisi, bentuk pakan juga memengaruhi efektivitas dan efisiensi pemberian pakan. Pakan dalam bentuk wafer memiliki kelebihan dalam kemudahan penanganan, penyimpanan, serta menjamin keseimbangan nutrisi sesuai komposisi pakan, sehingga dapat mengoptimalkan produktivitas ternak. Pemberian pakan wafer dengan penambahan selenium organik diharapkan mampu meningkatkan reproduktivitas induk domba Cross Merino sekaligus menurunkan tingkat mortalitas.Implementasi pakan wafer dengan selenium organik juga menjadi solusi dalam pemanfaatan bahan pakan lokal serta menjaga kualitas pakan agar dapat tersedia sepanjang tahun. Metode kegiatan pengabdian meliputi sosialisasi, pelatihan dan praktik, penerapan teknologi, pendampingan, serta evaluasi. Hasil kegiatan menunjukkan bahwa peternak Kelompok Ternak Sido Makmur mengalami peningkatan pemahaman mengenai penggunaan selenium organik sebesar 0,2 mg/kg pakan yang diaplikasikan dalam bentuk pakan wafer menggunakan teknologi hydraulic press. Peningkatan pemahaman ini menjadi indikator keberhasilan kegiatan pengabdian. Dengan demikian, teknologi pakan wafer berbasis selenium organik berpotensi diterapkan secara berkelanjutan untuk menurunkan mortalitas ternak dan mendukung keberlanjutan usaha ternak domba di Kelompok Ternak Sido Makmur.

Abstract

Sheep farming in Indonesia is generally still carried out conventionally to semi-intensively, and there is also minimal support for the sheep farming business being run. Livestock partners from CV An-Kim Indo Farm and Faris Jaya Farm are partners who still run sheep farming businesses by relying on the availability of green fodder in the form of field grass and rice straw as their main feed. Both of these feed ingredients have low nutritional quality. The level of sheep productivity is maintained if the feed contains a minimum of PK 10.90-12.70%, and TDN 55-60%. This factor causes the sheep of partner farmers to not be able to produce optimally. In fact, other feed sources besides field grass are widely available around partner farms and can be used as alternative feed, for example various agricultural waste. However, the low knowledge and skills of farmers in identifying and processing alternative feeds cause the nutritional needs of sheep not to be met and affect their productivity. The solution to this problem is to conduct socialization regarding increasing the nutritional value of animal feed through the manufacture of complete feed using alternative feed raw materials from agricultural waste. Complete feed silage innovation is a practical solution to overcome the availability of fresh feed for partner sheep farmers at CV An-Kim Indo Farm and Faris Jaya Farm. This silage saves labor and time, reduces dependence on field grass, its application is expected to improve feed management, save time and energy for farmers, and increase efficiency.

Abstract

Sweet corn (Zea mays L. Var saccharata Sturt) has a high demand in Indonesia, but its productivity is threatened by drought; therefore, it is necessary to analyze its growth under drought stress conditions. This study aims to observe the morphological and physiological responses of sweet corn plants to drought stress and potassium administration. The research was conducted over a three-month period at the experimental garden of the Faculty of Agriculture, University of Riau. A Factorial Completely Randomized Design (RA LF) was used with two factors: drought stress and potassium fertilization. The study consisted of three levels of potassium fertilization, with three replications, resulting in a total of 18 experimental units. The first factor: A1 = everyday; A2 = drought stress. The second factor: K 1 = 2.3 g K 2 O plant -1; K 2 = 2.8 g K 2 O plant -1; K 3 = 180 kg K 2 O ha -1. Analysis of Variance was continued with the Honestly Significant Difference (HSD) test at 5% level. The observed parameters consisted of physiological and morphological factors in sweet corn plants. The study found that drought stress negatively impacted the physiological parameters of sweet corn, including reduced plant water content and increased proline levels. Additionally, drought stress decreased key morphological traits, including plant height, root condition, cob husk weight, cob husk length, and cob husk diameter. However, the application of potassium fertilizer, particularly at a dose of 3.4 g K₂O plant-1, significantly improved the length of the cob husk. Overall, increasing potassium application under drought stress conditions tended to enhance both morphological and physiological parameters of sweet corn.
