This research was conducted to determine the effect of moringa leaf extract supplementation as a source of natural antioxidants in a complete ration based on fermented citronella oil distillation by-products on the content of crude fiber, crude fat, and nitrogen-free extract. This research used a Completely Randomized Design, five treatments, and three replications for each treatment. The treatments consisted of antioxidant supplementation with doses: of 0% (P0/control), 0.125% (P1), 0.25% (P2), 0.375% (P3), and 0.50% (P4). The variables measured included crude fiber, crude fat, and NFE content. The results of the study showed that the lowest average crude fiber content was in treatment P3 (25.43%), the lowest crude fat content was in P4 (1.88%), and the highest NFE content was in P4 (47.83%). Supplementation of moringa leaf antioxidants in fermented lemongrass waste-based rations with various doses (0%, 0.125%, 0.25%, 0.375%, 0.50%) showed no significant effect (P>0.05) on crude fiber, crude fat, and BETN content. The research concludes that supplementation of moringa leaf extract as a source of natural antioxidants showed no significant effect on crude fiber, crude fat, and NFE content

This study aims to determine the effect of substituting native grass with citronella waste on the digestibility of ruminants' dry matter, organic matter, and crude protein. A completely randomized design with 6 (six) treatments and 3 (three) replications is used in this research. The treatments were as follows: P1 = 50% native grass + 0% citronella waste + 50% concentrate; P2 = 40% native grass + 10% citronella waste + 50% concentrate; P3 = 30% native grass + 20% citronella waste + 50% concentrate; P4 = 20% native grass + 30% citronella waste + 50% concentrate; P5 = 10% native grass + 40% citronella waste + 50% concentrate; and P6 = 0% native grass + 50% citronella waste + 50% concentrate. The results showed that substituting native grass with citronella waste significantly affects (P<0.01) the digestibility of dry matter, organic matter, and crude protein. The highest digestibility values were observed in the treatment using 100% native grass, with dry matter digestibility at 52.67%, organic matter at 56.58%, and crude protein at 67.55%. The study concludes that while native grass cannot be entirely replaced by citronella waste, it can substitute up to 50% of the complete feed when native grass availability is limited.

This research aimed to determine the effect of adding red passion fruit juice (Passiflora edulis) on fat content, protein content, and elongation of mozzarella cheese. This research used an experimental method with a Completely Randomized Design with 4 treatments, namely giving red passion fruit (Passiflora edulis) (0%, 6%, 8%, and 10%) with 4 repetitions. The research results on the average fat content for each treatment were, P0 (15.97%), P1 (15.33%), P2 (13.25%), and P3 (12.69%). protein is P0 (21.70%), P1 (22.29%), P2 (23.24%), P3 (23.86%). The results of the research on the average elongation are, P0 (66.50cm), P1 ( 83.50cm), P2 (85.25cm), and P3 (91.25cm). Based on the research results it can be concluded that giving red passion fruit juice (Passiflora edulis) has a very significant effect (P<0.01) on fat content and protein content and was not significantly different (P>0.05) on the elongation of mozzarella cheese. The best treatment was found in the treatment without the addition of red passion fruit juice (Passiflora edulis) for protein and fat content while the best elongation was obtained in the treatment with the addition of 10% red passion fruit juice (Passiflora edulis).

Kelompok tani Garpondo merupakan kelompok tani yang bergerak dalam pembibitan dan penggemukan sapi potong unggul jenis Simmental. Permasalahan yang dihadapi oleh kelompok mitra selama ini adalah rendahnya tingkat kelahiran anak sapi denis kelamin jantan yang bisa dijadikan sebagai bakalan untuk penggemukan. Selanjutnya, hasil sampingan dari feses dan urin sapi tidak termanfaatkan untuk diolah menjadi sumber energi alternatif seperti gas bio. Solusi yang akan diterapkan untuk mengatasi masalah mitra ini adalah melakukan aplikasi inseminasi buatan dengan spermatozoa hasil sexing (jantan). Dengan ketersedian spermatozoa hasil sexing jantan dari tim pengabdian, maka aplikasi penerapan teknologi dengan inseminasi buatan akan menghasilkan kelahiran anak sapi jantan yang di inginkan oleh mitra karena nilai jual yang tinggi dan penggemukan dengan mudah. Selanjutnya melakukan pengolahan limbah peternakan seperti feses dan urin untuk pembuatan gas bio sebagai energi alternatif bagi kelompok mitra. Pembuatan gas bio ini menggunakan drum air kapasitas 1.100 liter/unit sebagai biodegester dan bisa menghasilkan gas bio yang siap dipakai oleh mitra. Ampas feses hasil fermentasi gas bio tersebut selanjutnya diolah lagi menjadi pupuk kompos yang bisa di jual kepada petani untuk tanaman pertanian dengan harga Rp. 25.000/karung. Metode yang dipakai dalam pencapaian tujuan tersebut adalah dengan penyuluhan dan praktek langsung ke lokasi mitra. Peternak juga akan dilatih dan diterapkan pembuatan fermentasi limbah pertanian sebagai alternatif pakan ternak.

Sapakek Basamo adalah satu kelompok tani ternak yang berada di Rimbo Berantai Kelurahan Tanah Garam Kecamatan Lubuk Sikarah Kota Solok yang berdiri sejak tahun 2019. Jenis usaha yang dijalankan adalah pegembangan usaha ternak sapi pembibitan dan penggemukan sapi potong unggul jenis Simmental. Permasalahan yang dihadapi oleh kelompok tani ternak selama ini adalah masih rendahnya ketersediaan pakan yang berkualitas serta rendahnya ilmu pengetahuan tentang upaya pencegahan dan pengendalian penyakit pada ternak sapi baik pada kelompok sapi pembibitan maupun sapi penggemukan. Umumnya pemberian pakan berupa hijauan rumput lapangan, jerami padi dan ampas tahu, hal ini menunjukkan rendahnya kualitas pakan yang diberikan dan menyebabkan pengembangan sapi bibit dan sapi penggemukan berjalan lambat. Pada kegiatan pengabdian kepada masyarakat ini diberikan penyuluhan ilmu pengetahuan terutama tentang penyediaan pakan berupa tehnologi pakan fermentasi dan upaya pencegahan dan pengendalian penaykit mulut dan kuku yang sedang mewabah pada saat ini. Metode yang dipakai dalam kegiatan pengabdian ini berupa metoda penyuluhan/ceramah dan diskusi bersama anggota kelompok tani ternak. Dari hasil pengabdian ini anggota kelompok tani ternak sangat antusias mengikut kegiatan penyuluhan dan berdiskusi langsung bersama tim pengabdian. Tehnologi penyediaan pakan ternak dengan fermentasi sudah dipahami begitu juga pentingnya upaya pencegahan dan pengendalian penyakit mulut dan kuku pada ternak. Peternak mengharapkan sekali untuk dilaksanakan kegiatan vaksinasi PMK oleh pihak terkait sebagai upaya pencegahan PMK.

The purpose of this study is to determine the quality of epididymis spermatozoa of buffalo after preservation with TALP media by adding serum with different level. The method used in this study is the experimental method and the design used is a randomized block design (RBD) with 3 treatment by adding bovine serum (0%, 5%, and 10%) and there are 6 replications as a group (repetition in the form of days). The result showed that the addition of serum into TALP diluent had a significant effect (P>0, 05) on the percentage of the motility of cauda epididymis spermatozoa of swamp buffalo after preservation which was 73, 33 in P2 10% serum and the viability is 79,167 ± 2,04 on P2 10%. This can be used as an indicator that the serum is effective in protecting spermatozoa from damages during the cryopreservation process, so by that, it would improve the quality of cauda epididymal spermatozoa of swamp buffalo. While the percentages of abnormality of cauda epididymis spermatozoa of swamp buffalo after preservation did not have a significant effect (P>0, 05). Based on the result of this study it can be concluded that the addition of 5% serum and 10% addition of egg yolk and 5% addition of glycerol will improve the quality of motility and viability and had no adverse effect on abnormalities after the preservation process at low temperature.
