PENGENCER SEMEN YANG DIPERKAYA MINYAK IKAN MENJAGA KUALITAS SPERMATOZOA BABI (Sus scrofa domesticus) SELAMA PENYIMPANAN JANGKA PENDEK Fish Oil Enriched Semen Extender Protect Boar (Sus scrofa domesticus) Spermatozoa Quality During Short Term Storage

Parsaoran Silalahi — 2026-06-21

This study aimed to evaluate the effect of fish oil addition to semen extender on the quality of boar spermatozoa during 24-hour storage at 15°C. Fresh semen was collected from a healthy adult boar with initial motility ≥70% and diluted using a glukosa–sitrat–EDTA extender supplemented with 0 g (P0), 0.15 g (P1), 0.30 g (P2), and 0.45 g (P3) of fish oil per 1.000 mL. The experiment was arranged in a completely randomized design (CRD) with four treatments and four replications. Parameters observed included motility, viability, abnormality, and semen pH after 24-hour storage. Analysis of variance showed that fish oil addition had a highly significant effect (P<0.01) on sperm viability, but no significant effects (P>0.05) on motility, abnormality, or pH. The highest viability was found in P1 (93.25%) and the lowest in P3 (82.00%). Motility and abnormality improved at low doses but declined at higher concentrations. The pH values remained stable (6.7–7.2) across all treatments. In conclusion, adding a low dose of fish oil (0.15 g/1.000 mL) effectively maintained spermatozoa quality without altering extender chemistry, suggesting its potential as a natural additive for semen extender formulations in tropical artificial insemination programs.

THE EVALUATION OF FROZEN SEMEN PRODUCTION POTENTIAL IN ETAWAH GRADE AND ANGLO-NUBIAN BREEDS (Evaluasi Potensi Produksi Semen Beku pada Kambing Peranakan Etawah dan Anglo Nubian)

Casmuti Casmuti — 2026-06-21

This study aimed to evaluate the potential of frozen semen production in Etawah Grade and Anglo-Nubian breeds based on fresh semen characteristics and to assess variations among individuals and breeds. The research was conducted at the Lembang Artificial Insemination Center, West Bandung, using primary data from five ejaculations per individual and secondary data from the year 2024. Fresh semen was evaluated for semen volume, sperm motility, and sperm concentration, reflecting the number of straws that can be produced per ejaculation. Frozen semen production potential was calculated based on semen volume, sperm motility, and sperm concentration. The results showed significant differences (P<0.01) in production potential among individuals and between breeds. The highest production potential was observed in the buck named Andromeda (122.45 ± 2.07 straws), which was significantly higher than that of other individuals. Anglo-Nubian breed showed a higher production potential (105.76 ± 2.54 straws) compared to Etawah Grade (91.63 ± 1.92 straws). However, Etawah Grade bucks exhibited relatively better sperm motility. In conclusion, both individual and breed factors significantly influence frozen semen production potential. Anglo-Nubian bucks have higher production capacity, while Etawah Grade bucks may offer better sperm quality. These findings provide important insights for optimizing breeding strategies and semen production planning in artificial insemination programs.

KARAKTERISTIK ORGANOLEPTIK DAN FISIKO-KIMIA PRODUK SUI WU’U DENGAN PENAMBAHAN TEPUNG BERAS MERAH (Organoleptic and Physico-Chemical Characteristics of Sui Wu’u Products wuth The Addition of Red Rice Flour)

Rosalia Rosinta — 2026-06-21

Sui wu'u is a pork product typical of the people of Flores (Ngada), East Nusa Tenggara, and has been passed down through generations since ancient times. This dish is made from pork preserved in a unique way using corn flour and salt, then stored in bamboo segments (tuku).This study aims to determine the effect of adding red rice flour on the organoleptic and physicochemical quality of sui wu'u. This study used a Completely Randomized Design (CRD) with 4 treatments and 4 replications. The treatments included P₀ (control without red rice flour), P₁ (10% red rice flour), P₂ (20% red rice flour), and P₃ (30% red rice flour) from corn flour. The results showed that the addition of red rice flour significantly affected the color of sui wu'u (P<0.01), where the color changed from bright red to dark red at 30% treatment. Aroma, taste, and tenderness did not experience significant changes (P>0.05). The treatment did not affect pH and water activity (P>0.05), but significantly affected protein content, fat content, fat oxidation and anthocyanin (P<0.01) with a decrease in protein and fat content and an increase in anthocyanin content at the highest treatment (P₃). It was concluded that the addition of red rice flour up to 30% had a positive effect on several physico-chemical quality parameters (except protein content) of sui wu'u without significantly changing the organoleptic properties except color.

Daniel Kurniawan Tulle Dani Tulle — 2026-06-21

Artificial insemination is a modern livestock breeding method that has been widely applied and proven effective in commercial farming systems. This study aimed to evaluate the success of artificial insemination using three types of semen extenders, namely Tris-egg yolk (T-EY), Citrate-egg yolk (C-EY), and Beltsville Thawing Solution-egg yolk (BTS-EY), supplemented with optimal levels of Moringa oleifera leaf extract (MLE), in order to determine the best extender. A total of 18 sows aged 1–2 years were inseminated using liquid semen. A descriptive method was applied to analyze non-return rate (NRR) and conception rate (CR), while a completely randomized design (CRD) was used for service per conception (S/C). The treatments consisted of P1: artificial insemination using T-EY + 2% MLE, P2: C-EY + 4% MLE, and P3: BTS-EY + 2% MLE. The observed variables were NRR, CR, and S/C. The results showed that the T-EY + 2% MLE extender achieved the highest CR and NRR, both reaching 100%, with an S/C value of 1.00. Meanwhile, the C-EY + 4% MLE and BTS-EY + 2% MLE treatments resulted in CR and NRR values of 83.33%, with an S/C value of 1.16. It can be concluded that the T-EY extender supplemented with 2% *Moringa oleifera* leaf extract was the best extender for liquid semen preservation of Landrace boars in artificial insemination programs.

CHEMICAL AND ORGANOLEPTIC QUALITY OF SMOKED SALTED EGGS WITH THE ADDITION OF HERBAL INGREDIENTS GINGER AND TURMERIC

Salma Sania — 2026-06-21

The addition of herbal ingredients such as turmeric and ginger can increase the durability and shelf life of smoked salted eggs. The active compounds curcumin and gingerol are thought to play a role in increasing the quality of salted eggs. This study aims to analyze the effect of adding turmeric and ginger on the chemical and organoleptic properties of smoked salted eggs. The method used was a Completely Randomized Design (CRD) with four treatments: P₀ (control), P₁ (turmeric 7.5%), P₂ (ginger 7.5%), and P₃ (combination of turmeric and ginger 7.5%), each with five replications. The parameters observed included ash content, salt content, crude fiber, and organoleptic tests (color, aroma, texture, and preference). The results showed that the addition of turmeric and/or ginger had a significant effect on ash content, color, aroma and had a very significant effect on crude fiber content, but had no significant effect on salt content, texture and preference level. The mineral and crude fiber content in turmeric and ginger contributed to the increase in ash and crude fiber content. Meanwhile, the addition of turmeric and ginger in the salted egg mixture does not affect the salt content, so the salty taste remains balanced, neither excessive nor lacking. The best results were obtained in the combination treatment of 7.5% turmeric and 7.5% ginger (P₃) with an ash content of 12.27%, a salt content of 4.00%, crude fiber of 4.41%, and an organoleptic score for color of 4.07, aroma of 3.60, and a preference level of 3.47. Thus, the use of a combination of turmeric and ginger can be an alternative in improving the quality and durability of smoked salted eggs without changing the balance of taste.

KUALITAS TELUR AYAM ARAB KONSUMSI DAN PERUBAHAN MUTUNYA SELAMA PENYIMPANAN PADA SUHU YANG BERBEDA (Quality Changes of Arabian Chicken Table Eggs During Storage at Different Temperatures)

Herwin Pisestyani — 2026-06-21

The quality of Arabic Chicken table eggs (Gallus turcicus) and changes in quality during storage at room temperature (25–27 °C) and refrigerated temperature (4–7 °C) were evaluated. A total of 200 fresh eggs obtained from Arabic laying hens at peak production (30–40 weeks of age) were assigned to two storage temperature groups. Measurements were performed on days 0, 5, 10, 15, 20, 25, 30, 35, 40, and 45, using five eggs per group at each sampling time. External quality (egg weight and air cell height) and internal quality (yolk index, albumen index, and Haugh Unit) parameters were determined. Data were analyzed using two-way analysis of variance (ANOVA) to assess the effects of storage temperature, storage duration, and their interaction, followed by Tukey's post hoc test. Storage temperature, storage duration, and their interaction were found to have significant effects (P < 0.05) on air cell height, yolk index, and Haugh Unit. A significant temperature–time interaction indicated that the rate of egg quality deterioration depended on both storage temperature and storage duration. Eggs stored at room temperature exhibited faster quality deterioration, which was detected as early as day 10 of storage, as evidenced by decreased yolk index and Haugh Unit values and increased air cell height. In contrast, eggs stored under refrigerated conditions showed greater stability, with internal quality maintained until days 40–45 of storage. Overall, refrigerated storage was more effective than room-temperature storage in maintaining the quality of Arabic chicken table eggs.

ANALISIS INDEKS ANIMAL WELFARE KUDA PADA PASAR KUDA TRADISIONAL (Analysis of the Horse Animal Welfare Index in Traditional Horse Market)

Ayu Lestari — 2026-06-22

This study aims to analyze the animal welfare index for horses sold at the Horse Market in Jeneponto Regency. A mixed methods approach was used, combining quantitative and qualitative data. Quantitative data were obtained through observations of 100 horses using the Five Freedoms principle, assessed on a scale of 1-5, while qualitative data were collected through interviews with traders, buyers, and market managers. Data were analyzed descriptively by calculating the animal welfare index based on the average score of all observed indicators. The results showed that the horse animal welfare index was 2.16, which is considered adequate. The highest score was for freedom from pain/injury/disease (3.56), categorized as good, while the lowest score was for freedom from hunger and thirst (1.00), categorized as poor. Freedom from discomfort (1.73) and freedom to express natural behavior (2.00) were also considered low, while freedom from stress was considered adequate (2.50). The low implementation of animal welfare is influenced by limited market facilities, high livestock density, unhygienic environmental conditions, and market participants' poor understanding of animal welfare principles. This study shows that the implementation of animal welfare in horse trading in traditional horse markets is still not optimal, so that improvements in facilities, improved market management, and education related to animal welfare for all market players are needed to support a more sustainable and ethical livestock trading system.
