The objective of research was to evaluate the effect of different level of decomposers from bioethanol waste as a bioactivator to compost nutrient content. The materials used in this study were feces collected from six 3 to 5 years old of male Fresian Holstein (PFH), and decomposer agents from processed-bioethanol waste. The experimental design used was completely randomized design with four treatments and six replications, i.e. P1: 0.4% of decomposer, P2: 0.5% of decomposer, P3: 0.6% of decomposer, P4: 0.7 of decomposer %. Analysis of nutrient contents of compost was conducted at the the Laboratory of Chemistry and Soil Fertility, Department of Soil Science, Faculty of Agriculture, Gajah Mada University, Yogyakarta. Data analysis was performed using Minitab 17 software. The results of the analysis of variance showed that different levels of decomposer affected organic C, phosphor (P), Kalium (K), and Magnesium (Mg). Organic C, P, K, and Mg contents were found highest in P2, on the other hand N and Ca contents, C/N ratio, pH, and temperature of compost were not different among treatments. It could be concluded that compost made with 0.5% decomposer agents from processed-bioethanol waste was the best.

Pemberian pakan komplit yang mengandung limbah pertanian kepada ternak akan meningkatkan utilitas bahan pakan terutama limbah pertanian. Pengawetan dengan cara silase bisa menjadi solusi saat pakan sulit ditemukan di musim kemarau. Silase yang ditambahkan additif akan meningkatkan kualitas fermentasinya. Penelitian ini bertujuan untuk mengkaji pengaruh yang ditimbulkan dari pakan silase pakan komplit dengan aditif fermented juice lactic acid bacteria (FJLB) yang berbeda terhadap imbangan energi dan nitrogen ternak domba lokal. Sebanyak 12 ternak domba lokal jantan dengan bobot badan awal 17,67 ± 1,7 kg (umur 12 bulan) disusun dalam rancangan acak lengkap. Ransum terdiri dari jerami padi, bungkil kedelai, jagung, dedak padi, pollard dan mineral mix yang disilase menjadi pakan komplit selama 3 minggu. Perlakuan dalam penelitian ini antara lain yaitu T1= Silase tanpa aditif FJLB, T2= Silase dengan aditif FJLB dari Pennisetum purpureum, T3= Silase dengan aditif FJLB dari Pennisetum purpupoides, dengan 4 ulangan tiap perlakuan. Analisis data menggunakan uji ANNOVA. Hasil penelitian menunjukkan bahwa konsumsi energi dan energi tercerna pada T2 lebih rendah dibandingkan dengan control dan T3. Pemberian FJLB memberikan nilai kecernaan energi, energi termetabolisme, dan energi metana yang sama di semua perlakuan. Penambahan aditif FJLB menurunkan konsumsi protein kasar, namun aspek protein kasar tercerna, kecernaan protein kasar, protein kasar termetabolisme, dan allantoin menunjukkan nilai yang sama dengan kontrol. Dapat disimpulkan bahwa perbedaan penambahan aditif FJLB pada silase pakan komplit masih memberikan deposisi energi dan protein yang sama.

This community service activity aimed to provide outreach through knowledge about feeding management and parasitic diseases in horses. Community service activities by the TAP&D (Tropical Animal Production and Disease) Research Group were held at the Bendi Horse Sukoharjo community group on June 25, 2023, in Sukoharjo Regency, Central Java. Data were collected using interviews and observation. All data obtained were then analyzed descriptively. The horses used are descendants of Banyuwangi horses. This bendi is used by the owner to attract or transport tourists who come to Sukoharjo Square every Monday to Sunday. The horses used are generally small, and some are even skinny. After analyzing horse faeces in the laboratory at the start of the pre-survey, it was found that 100% of the bendi horses in the association were infected with worms. Diseases in horses can also be caused by poor feed management. So, the solution is to provide education on maintaining good horse practices, especially feed management. The next problem is that the feed given to horses usually consists of long grass, so the horse doesn't eat all the parts. The solution we provide is a grass chopper. After the service activities were carried out, farmers increased their knowledge regarding parasitic diseases in horses and good feed management. This service activity concludes that horse farmers have increased knowledge about good horse care and about horse diseases.

Lifting aircraft or crane is a combination of a lifting mechanism separately with a frame to lift and or simultaneously move loads that can be hung freely or tied to a crane. Part of the crane hoist has a main component called a crane hook that functions as a load or material hook. The hook is one of the hoisting elements that is very important in crane operations[9]. The types of hooks differ in terms of function, material, form and safety factor, so they must be analyzed, inspected and tested properly so as not to endanger workers in the field. The analysis was carried out numerically using Autodesk Inventor Professional 2020 software[2] . Analysis of hooks generally uses analytical methods or calculations with mathematical models and standardized (common) Algebraic formulas, along with the development of technology today, many engineering sciences have been developed in the field of finite element science which unites mathematics, engineering and science. computer to produce software such as Autodesk Autocad, Autodesk Inventor. In the simulation results of the finite element software on the hook for a loading of 25 tons, the single hook type obtained a maximum stress of 807.809 MPa and the deflection that occurred was 1.444 mm, in the double hook type the maximum stress was 532.632 MPa and the deflection was 0.1871 mm. The simulation results will then be compared with the results of analytical calculations. Analytical calculations for single hooks obtained working stress of 761,729MPa, on double hooks of 387,102 Based on the simulation results and analytical calculations, it can be concluded that the crane hook structure is still within safe limits. This is because the yield strength of the material used in AISI A514 alloy steel is 890 MPa. However, of the three types of hooks at a loading of 25 tons, single hooks have the greatest potential for failure.

Soybean groats and earthworms (Lumbricus rubellus) are natural sources of protein, which are easy to obtain. Therefore, this research aims to evaluate the effects of protected soybean groats (PSG) and earthworm meal (PEM) in the diet on estrus response, milk production and composition of Saanen Peranakan Etawa (Sapera) dairy goats. These feed supplements were further protected by 1% formaldehyde. A completely randomized design with three treatments consisting of basal diet (P0), 75% basal diet + 25% PSG (P1), and 74.96% basal diet +24.99% PSG and 0.05% PEM (P2) was used in this research. Also, a total of 21 lactating Sapera goats were utilized and equally grouped into these treatments. Milk productions and composition were recorded and checked using a Lactoscan milk analyzer. Moreover, estrus synchronization was applied using the PGF2α and GnRH hormone using the intramuscular (IM) injection method and observing estrus. The data were analyzed using one-way analysis of variance while the differentiation of treatments was conducted with Duncan's multiple range test (DMRT). Electrical current resistance, vaginal temperature, vulva color, milk production, fat, total solids, and protein contents were observed to be significantly affected by the supplementation of PSG and PEM (P<0.05). In conclusion, supplementation of PSG and PEM in the diet could improve estrus response, milk production and composition of Sapera goats.
