Comparison of the quality of beef from Jagalan RPH Production and Non-RPH Production

Ayu Pramudita — 2025-06-30

Meat quality is determined based on aspects of handling, inspection, environment and facilities at the slaughterhouse. Some of these aspects have been paid attention to by slaughterhouses (RPH), but they are still less of a concern for places that carry out independent slaughtering. The aim of this research is to determine the difference in the quality of meat from RPH production and meat from production other than RPH. Parameters used in meat quality testing include organoleptic tests (color, odor, consistency and cleanliness), pH tests and Water Holding Ability (DIA) tests. Data were analyzed using the Kruskal Wallis test, if there were significant differences, it was continued with the Mann Whitney test. The results showed that there were significant differences in color quality, consistency, pH and DIA values (P<0.05). Meanwhile, the results did not show significant differences in bau and cleanliness parameters (P>0.05). However, meat originating from both places is still at a level suitable for consumption

Identification profile with extensive and semi-intensive beef cattle production system in District Sorong, Southwest Papua Province

Indra Saputra — 2025-06-30

The farmes in Southwest Papua, have started using the semi-intensive farming system for Beef Cattle rearing in recent decades. This study aimed to determine the profile profile of beef cattle farmers under with extensive and semi-intensive farming systems in Sorong Regency, Southwest Papua Province. This research was conducted from January to March 2024 using the Participatory Rural Appraisal method, which is an approach that involves family members or individuals to analyze the reality of the living conditions they live in. This research involved 100 breeders divided into 60 extensive farmers and 40 semi-intensive farmers who were selected using purposive sampling. Data were described quantitatively and analyzed using the independent T test. The results showed that the age of farmers in the semi-intensive system was younger but their farming experience was longer in the extensive system (P<0.05). The motivation for keeping livestock as savings, the main livelihood and the function of livestock as a fertilizer producer are not significantly different, but breeders in different rearing systems view that the motivation for keeping livestock as savings is still very important. The number of cows in the extensive system was higher than in the semi-intensive system (P<0.05). It was concluded that farmers with extensive and semi-intensive farming systems use cattle more for savings and insurance purposes compared to breeders whose background is in animal husbandry as their main occupation and fertilizer producer

Diversity and potential of nuisance flies as vectors of gastrointestinal parasitic diseases in traditional markets in Surabaya City

Marek Yohana Kurniabudhi — 2025-06-30

Nuisance flies are known mechanical vectors capable of transmitting bacterial agents, protozoa, and helminth eggs—particularly Soil-Transmitted Helminths (STH)—from traditional market environments to human food. This study aimed to identify the diversity and distribution of nuisance fly species and to investigate the presence of gastrointestinal parasites in these flies at traditional markets in Surabaya City. Fly samples were collected from five traditional markets and examined using native, sedimentation, and flotation techniques under a microscope. Descriptive statistics were employed to analyze species diversity, relative Abundance, frequency, dominance, and Shannon-Wiener diversity index (H'). The identified species included Chrysomya megacephala, Chrysomya saffranea, Lucilia sp., Musca domestica, and Sarcophaga sp., with M. domestica being the dominant species across all markets. Endoparasitological examination revealed the presence of protozoa and helminth eggs. Entamoeba sp. was consistently detected (100%) in both fly genera, while Isospora sp. oocysts were exclusively found in M. domestica from Wonokusumo Market. Ancylostoma sp. and Toxocara sp. eggs were identified in M. domestica from several markets and in Chrysomya sp. from Kaliwaron LKMK Market. The presence of these parasites is likely due to the flies’ contact with contaminated substrates such as sewage, market waste, animal carcasses, or vegetables. These findings underscore the importance of nuisance fly surveillance, as these insects not only cause discomfort but also act as vectors of zoonotic pathogens posing health risks to animals and humans.

Evaluation of molecular primers for sexing the magpie robin and green cucak via CHD1 gene amplification

Khilmi Fuadah — 2025-06-30

Researchers and breeders are increasingly using the Polymerase Chain Reaction (PCR) method for bird sexing. However, the compatibility of the DNA template and the oligo primer used is the primary key to the success of PCR amplification. In the present study, we evaluated five types of popular PCR primers sexing to determine the sex of a pair of each the magpie robin (Copsychus malabaricus) and green cucak (Chloropsis sonnerati). We used DNA samples from each pair of males and females from the two species above, respectively, to test the five primers listed to amplify the target gene chromodomain helicase DNA binding 1 (CHD1). The results demonstrated that the primer sets of CHD1LF/CHD1LR, CHD1F/CHD1R, and P2/P8 could be used for Copsychus malabaricus, while only CHD1LF/CHD1LR was suitable for Chloropsis sonnerati. It is crucial to select the correct primer to improve bird sexing accuracy because several of the other primers examined in this study were unable to amplify the targeted CHD1 gene correctly.

The potential of utilizing food waste as pig feed in Sentani District, Jayapura Regency

Max Rumbrapuk — 2025-06-30

The increasing demand for sustainable livestock feed sources has sparked interest in the reutilization of food waste. This study aims to assess the quantity, types, and nutritional content of food waste generated from households, restaurants, and hotels in Sentani District, Papua, Indonesia, and evaluate its potential as an alternative feed for pigs. A descriptive mixed-method approach was employed, involving field surveys, structured interviews, and laboratory analysis. Daily food waste production was highest in hotels (33.00 kg/day), followed by restaurants (8.64 kg/day) and households (5.33 kg/day). Nutritional analysis showed that dry matter content was highest in restaurant waste (29.74%), moderate in hotel waste (28.03%), and lowest in household waste (17.19%). The study reveals that hotel and restaurant waste is richer in nutrients and more consistently available, making it a more suitable feed source. However, high moisture content in household waste necessitates prompt handling and processing. These findings highlight the potential of food waste to enhance feed sustainability, reduce costs, and support environmentally responsible livestock practices in rural Papua New Guinea.
