The rabbit farming business has great potential to meet the need for animal protein, and currently, many rabbit farming businesses are being cultivated. Farmers face nonoptimal reproductive performance with the currently implemented mating management, so improvement efforts are needed. The community service aimed to implement good breeding practices through communal mating and introducing bucks Rex rabbits to rabbit breeders in Kulonprogo, Yogyakarta. The community service activities were conducted from June to September 2023 at one of the rabbit breeders in Kulonprogo Regency, Yogyakarta. The activities include: 1. initial preparation and coordination, 2. preparation of extension materials, guidebooks (assistance media), 3. Direct training through extension. 4. Implement communal mating, introduce Bucks Rex directly at partner locations, and distribute guidebooks. 5. Monitoring and evaluation of activity results. The enthusiasm of breeders in community service was proven by the presence of 30 breeders in extension and discussion activities with the theme "Kopi Darat Peternak Kelinci Komersial." The results of the application of the communal mating method show farmer satisfaction, with 4 out of 5 rabbits becoming pregnant from the application of this method. Increasing the reproductive performance of the breeder's doe can increase rabbit production, thereby contributing to the breeder's income. Implementing good breeding practices through communal mating and the introduction of bucks Rex rabbits can be a solution for breeders regarding the low productivity of the rabbits.

Beringin Raya Village's position, near the Bengkulu University campus and directly adjacent to Central Bengkulu Regency, should allow it to flourish as a satellite area. This location has the potential to become a new hub of activity, serving as a gateway between Bengkulu City and its neighboring districts. However, the development of the area surrounding the school in Beringin Raya Village is slower than that of neighboring villages nearby. The restrictions of regional expansion in the Beringin Raya sub-district resulted in the formation of spaces between residential settlements with a high potential for agricultural, livestock, and home industry development. The agricultural and livestock sectors are not the primary economic drivers in the Beringin Raya sub-district. The realities on the ground demonstrate that some individuals earn a living as farmers, particularly vegetable and horticulture growers who work in settlements. Identification of surrounding environmental resources in Beringin Raya Village is the first step toward understanding the potential problems, possibilities, and risks that will arise in the area. Field observations and conversations with community leaders are part of the data collection process. The next stage following identification is to establish priorities. The development of the area surrounding the Bengkulu University campus is a difficult task that necessitates a collaborative approach. Various variables are interconnected and impact one another in attempts to solve existing problems. The study programs of Bengkulu University play a vital role in contributing ideas, research, devotion, and solutions to help overcome or decrease current difficulties. Collaboration with the government, stakeholders, and local communities is essential for developing and executing effective policies.

Penelitian ini bertujuan untuk mengukur efektivitas penerapan fly trap dengan menggunakan antraktan berbahan telur ayam di kandang sapi potong. Penelitian dilaksanakan di kandang sapi potong Pusat Pengembangan Ternak (PPT) Fakultas Peternakan Universitas Gadjah Mada. Materi yang digunakan adalah alat fly trap atau perangkap lalat dan atraktan berupa telur ayam yang telah dikocok dan juga petrogenol. Atraktan dimasukkan ke dalam flay trap yang berbentuk tabung silinder. Perangkap berisi atraktan kemudian ditempatkan pada tiap-tiap petak kandang. Pengamatan dilakukan setiap hari hingga tidak ditemukan adanya lalat yang terperangkap di fly trap. Data yang dikaji meliputi daya tahan atraktan, jenis lalat, dan jumlah lalat yang terperangkap. Data dianalisis menggunakan analisis variansi pola searah. Antraktan berbahan telur ayam dan petrogenol mampu bertahan hingga tujuh hari, dan mampu menangkap lalat Musca domestica, Chrysomya megacepala, Bactrocera dorsalis, dan total lalat masing masing sebanyak 32,40±18,52 dan 1,20±1,09 ekor, 6,00±4,95 dan 0,00±0,00 ekor, 0,00±0,00 dan 2,80±1,64 ekor, serta 38,40±22,74 dan 4,00±2,55 ekor. Jenis lalat Musca domestica yang terperangkap pada telur ayam lebih tinggi (p<0,01) daripada petrogenol serta lalat Chrysomya megacepala yang terperangkap pada telur ayam lebih tinggi (p<0,05) daripada petrogenol. Namun, jumlah lalat Bactrocera dorsalis yang terperangkap pada telur ayam lebih rendah (p<0,01) dari pada petrogenol. Secara total jumlah lalat yang terperangkap pada atraktan berbahan telur ayam lebih banyak (p<0,01) daripada petrogenol. Disimpulkan bahwa aplikasi fly trap dengan menggunakan antraktan berbahan telur ayam lebih efektif dalam menangkap lalat di kandang sapi potong dibandingkan dengan menggunakan petrogenol.

ABSTRACT. Penelitian ini bertujuan untuk mengevaluasi penggunaan ekstrak daun senduduk sebagai antioksidan sosis daging sapi selama penyimpanan suhu ruang. Sebanyak 40 g bubuk daun senduduk dimaserasi dalam air destilata (1:4; b/v) selama 24 jam pada suhu kamar, disaring, kemudian di-freeze dry. Lima perlakuan diaplikasikan, yaitu kontrol yang mengandung daging sapi, minyak nabati, susu skim bubuk, tepung tapioka, garam, fosfat, es, dan bumbu-bumbu (P1); formula kontrol ditambah dengan butylated hydroxytoluene 0,01% (P2), formula kontrol ditambah ekstrak daun senduduk 0,5% (P3), formula kontrol ditambah ekstrak daun senduduk 0,75% (P4), dan formula kontrol ditambah ekstrak daun senduduk 1% (P5). Variabel yang diamati adalah susut masak, daya mengikat air, aktivitas antioksidan, nilai Tio barbituric acid reactive substances (TBARS). Hasil penelitian menunjukkan bahwa penambahan ekstrak daun senduduk menurunkan susut masak sosis dan tanpa memengaruhi karakteristik daya mengikat air. Penambahan ekstrak daun senduduk mampu meningkatkan daya hambat terhadap radikal bebas dan kapasitas antioksidan serta menekan nilai TBARS. Selama penyimpanan suhu pada ruang hingga 10 jam, aktivitas antioksidan mengalami penurunan tetapi tidak memengaruhi nilai TBARS. Kesimpulan dari hasil penelitian ini adalah penggunaan ekstrak daun senduduk hingga 1% dari berat daging dapat menekan oksidasi yang setara dengan butylated hydroxytoluene 0,01% pada sosis selama penyimpanan suhu ruang 10 jam.(Reducing oxidation in beef sausage during room temperature storage by adding senduduk (Melastoma malabathricum L.) leaf extract)ABSTRAK. This study aimed to evaluate the use of senduduk leaf extracts as an antioxidant beef sausage during room temperature storage. A-40 g powder was macerated with distilled water (1:4; w/v) for 24 h at room temperature, filtered, and then was freeze-dried. Five treatments were employed including control containing beef, vegetable oil, skimmed milk powder, tapioca, salt, phosphate, ice, and seasons (P1); control added butylated hydroxytoluene 0.01% (P2); senduduk leaf extract 0.5% (P3); senduduk leaf extract 0.75% (P4); and senduduk leaf extract 1% (P5). Variables observed were cooking loss, water holding capacity, antioxidant activity, and Tio barbituric acid reactive substances (TBARS). The results showed the addition of senduduk leaf extract could decrease the cooking loss without any effect on the water-holding capacity of the sausages. The addition of senduduk leaf extract increase the scavenging activity and antioxidant capacity and reduced TBARS value of the sausages. During storage, the antioxidant activity of the sausages diminished with no affect the TBARS value. It could be concluded that the addition of senduduk leaf extract 1% could retard lipids oxidation of the sausage and the capability was equal to butylated hydroxytoluene 0.01 during 10 hours of storage.
