Tannin is one of plant secondary metabolites that could protect proteins from various microbes, both in feed material and in rumen. Tannin can be used as an additive in the silage production process, especially high-protein feed material. The study aimed to evaluate the physical quality of soy sauce by-product silage treated with Acacia mangium Wild. tannin (AT; condensed tannin). This study used the fresh soy sauce by-product, tannin of acacia and chestnut (CT; hydrolysable tannin), BAL and propionate acid (PA). Soy sauce by-product was fermented in silo with a capacity of 1.3 Kg. This experiment was arranged in a complete randomized design with 6 treatments and 3 replications. The treatments were (R1) fermented soy sauce by-product, (R2) R1 + BAL, (R3) R1 + 2% AT, (R4) R1 + 2% CT, (R5) R1 + 0.5% PA and (R6) R1 + combination of 1% AT, 1% CT and 0.5% PA. The observed variables were the loss of dry matter (%), temperature (⁰C), smell, color and emerged fungus on silage. Analysis of variance was performed by SPSS version 23. For any significant difference between treatments was evaluated by DMRT at level of confident 5%. The result showed that AT suppressed the loss of dry matter up to 0.91%, and produced no smell with black color such as soybean color. The silage temperature was relatively similar for about 28.9-29.4 ⁰C, no emerged fungus, and did not able to maintain the normal silage temperature. Nevertheless, the use of acacia tannin could produce a good quality soy sauce by-product silage.

Desa Arang Limbung merupakan salah satu desa yang menerima program restorasi gambut dari Badan Restorasi Gambut (sekarang BRGM, Badan Restorasi Gambut dan Mangrove) di Kabupaten Kubu Raya, Provinsi Kalimantan Barat. Di desa ini, terdapat Kelompok Tani Makmur yang menerima program restorasi gambut berupa program Revitalisasi dalam bentuk usaha ternak kambing. Sebagai kelompok tani yang dibentuk untuk menerima program dari BRGM dengan latar belakang pekerjaan yang bukan peternak menyebabkan usaha ternak kambing yang dikelola oleh kelompok tani ini mengalami beberapa kendala. Selain sektor produksi ternak yang belum optimal akibat tingginya angka kematian anak kambing, usaha ternak kambing ini belum menghasilkan pendapatan yang memadai bagi anggota kelompoknya. Salah satu upaya yang dilakukan untuk meningkatkan sumber pendapatan dari usaha ternak kambing adalah mengelola limbah ternak berupa kotoran padat dan urin menjadi produk bokashi dan biourin yang dapat dijual. Peningkatan pengetahuan dan keterampilan untuk membuat bokashi dan biourin dilaksanakan melalui pelatihan yang diadakan pada bulan Juli 2022. Pelatihan tersebut dihadiri oleh 12 orang anggota kelompok Tani Makmur dan didampingi oleh tim pengabdian masyarakat dari Universitas Tanjungpura. Kegiatan pelatihan dilaksanakan melalui metode penyuluhan dan mempraktekkan secara langsung proses pembuatan bokashi dan biourin. Sebagian besar peserta pelatihan merasakan peningkatan pengetahuan dan keterampilan pada akhir kegiatan pelatihan dan berharap dapat menghasilkan produk bokashi dan biourin yang dapat digunakan dalam budidaya tanaman milik sendiri maupun dijual untuk menambah penghasilan keluarga

Sungai Kupah Village has a tourism awareness group (POKDARWIS) consisting of 30 people. Most of the group members work as fishermen or coconut gardeners. The tourist sites managed by the group are in the form of mangrove tourism. The tour is equipped with mangrove tracking facilities, photo spots, canteens, toilets, parking lots. During the pandemic, the number of tourists fell by almost 70%. Another factor that causes the low number of visitors is the lack of information about the location profile of digital-based mangrove ecotourism areas. Promotion is an important activity that plays an active role in introducing information and information about potential products so that a wider audience can understand their existence and can encourage audiences to visit the product or object to be opened. It is hoped that knowledge about the role and importance of mangroves can be disseminated to the wider community through this tourist attraction. One of the promotional steps that can be taken is to create a digital-based profile of the location of the mangrove ecotourism area, where all information will be conveyed to the public to build brand awareness. Lecturers play a role in implementing the Tri Dharma of Higher Education, namely Community Service in the form of participating in empowering and interacting with the community. in Community Service partners, namely POKDARWIS Ekowisata Standing, which is to improve the skills of mangrove tourism management partners in marketing tourism objects, producing mangrove tourism profile videos uploaded on social media and can increase visitors who come to mangrove tourism

This study developed slow-release urea (SRU) additives using autoclaved oil palm empty fruit bunches (OPEFB) and urea via wet granulation to improve nitrogen utilization in ruminants. OPEFB was autoclaved at 121°C and 1 atm pressure to create a stable matrix, which was then combined with urea in different proportions to form SRU. In the first phase, the physical and morphological properties of autoclaved and non-autoclaved OPEFB were analysed using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) were measured, with hemicellulose calculated as the difference between NDF and ADF. In the second phase, SRU formulations included varying percentages of urea and autoclaved OPEFB: SRU 100 (100% urea), SRU 98 (2% OPEFB), SRU 96 (4% OPEFB), SRU 94 (6% OPEFB), SRU 92 (8% OPEFB), and SRU 90 (10% OPEFB). SEM and FTIR descriptively showed surface changes in OPEFB after autoclaving, including increased porosity. Autoclaving also descriptively reduced NDF, ADF, lignin, cellulose, and hemicellulose contents. In vitro rumen incubation revealed that the addition of autoclaved OPEFB in SRU reduced urea release and pH in the rumen at various time intervals: 3, 6, 9, and 24 hours. SRU with autoclaved OPEFB optimizes urea use and controls nitrogen release.

Elephant grass is a common forage for livestock fodder, yet it is prone to damage and requires preservation through silage-making techniques. This study was investigating the potential usage of expired commercial syrup (ECS) as a source of glucose in elephant grass silage production. The research used a Completely Randomized Design with five treatments and five replications. Treatments included a control group that consist of elephant grass (P1/control), and four supplemented grasses with ECS at levels of 2.50% (P2), 5% (P3), 7.50% (P4), and 10% (P5) based on dry matter (DM). After ensiling for 30 days at room temperature, various parameters were measured, i.e. aroma, texture, color, fungal growth, pH, dry matter, dry matter loss (DML), and fleigh value. Data were analysis using analysis of variance, followed by Duncan's test. The results revealed that ECS incorporation up to 10% DM had a significant influence on the evaluated parameters (p<0,05). The results showed P5 received the highest ratings from panellists for aroma (3.75; distinctive fermented acidity), texture (3.61; fine and non-clumping), and color (3.54; green). Additionally, P5 exhibited minimal fungal growth (1.57%), an optimal pH range (3.24-4.56), the highest dry matter content (31.4%), the lowest dry matter loss (2.27%), and the highest fleigh value (138). The research concluded that expired commercial syrup could use as a stimulant additive in elephant grass ensiling, effectively.

Background: This study aimed to determine the effect of bitter leaf flour in ration with different levels of laying hens on the haematological profile. The materials used were 20 laying hens with Hy-line strain, 110 weeks old, placed in battery cages and feed with 16-18% crude protein content of 120 grams/head/day and drinking water addlibitum. Methods: The research was conducted using an experimental method with a completely randomized design four treatments that were repeated five times. The treatments were given in the form of bitter leaf flour in ration with levels of P0: 0% (control), P1: 1%, P2: 2%, P3: 3%. The variables measured were haematological profiles such as erythrocytes, haemoglobin, hematocrit and leukocytes. The data obtained were then analyzed using analysis of variance. Finding: The results showed that giving bitter leaf flour in ration with levels of 0%, 1%, 2%, and 3% had no significant effect (P>0.05) on erythrocytes, hemoglobin, hematocrit, and leukocytes of laying hens. Connclusion: It was concluded that giving levels of bitter leaf flour up to 3% did not affect the haematological profile of laying hens. Novelty/Originality of this Article: The novelty of this study lies in its exploration of bitter leaf flour (Vernonia Amygdalina) as a natural feed additive in the diet of elderly laying hens (110 weeks old), a topic that is still underrepresented in poultry research, especially regarding its effect on haematological health parameter.
