Abstract

This study aimed to investigate the effect of stocking density on stress indicator, carcass composition, and meat cholesterol content of kampung–broiler crossbred chicken. Anamount of 90 DOCs of crossbred kampung-broiler (KB) were placed into 9 plots sized 1x1 m2 in semi closed house that consist of 3 stocking densities 8, 10 and 12 birds m-2 and respectively 3 replicates. The chickens were fed commercial broiler feed. Approximately ± 30% roosters slaughtered for analysis of malondialdehyde, carcass quality, and meat cholesterol. Malondialdehyde, carcass composition, and meat cholesterol was completely randomized designed with different stocking densities treatments and three replicates. Data was analyzed using analysis of variance (ANOVA) and had previously been tested for requirement of variance test assumption. Data of temperature humidity index (THI) was descriptively explained. The results showed that the effect of different stocking densities on stress indicator reflected by THI value and MDA content, carcass composition (percentage of carcass and abdominal fat weight), and cholesterol level were not significant. The different of stocking densities (8, 10 and 12 birds m-2) did not affect the stress indicators reflected by THI and MDA level, carcass composition and meat cholesterol level. Kampung-broiler crossbred chicken could develop at 8, 10 or 12 birds m-2 densities since the lower of abdominal fat and meat cholesterol were resulted

Abstract

Indonesia has agreat variety of roosters, either indigenous type as well as exotic and cross breed. The purpose of this experiment was to study the characteristics of semen from three types of Indonesian local roosters such as Merawang, Kampung and crosses Sentul Kampung with Kedu (SK Kedu). A total of 15 roosters consist of  Merawang roosters,  Kampung, and SK Kedu roosters were 5 each. The semen was collected 3 times a week by dorso-abdominal and cloaca massage method. The parameters evaluation was macroscopic characteristics consist of volume, color, consistency, and pH. Microscopic evaluation of semen such as a mass movement, sperm motility, live sperm, sperm abnormality and sperm concentration. Results of this experiment showed that semen volume of  Merawang  (0.40±0.26 mL) was higher (p<0.05) compare to Kampung (0.24±0.12 mL) or  SK Kedu (0.16±0.10 mL) but no difference on semen color, consistency and semen pH. There were no difference in the mass movement, sperm motility and live sperm as well as on sperm abnormality among three types of roosters.  Sperm  concentration of Merawang (4490 million mL-1) was significantly higher than Kampung (3245 million mL-1) and the SK Kedu roosters (3751 million mL-1). Its was conclude that Merawang roosters had good semen quality better than Kampung and SK Kedu roosters

Abstract

Disamping semakin sulit dan mahalnya pemilihan lokasi Tempat Pemrosesan Akhir (TPA), munculnya penolakan masyarakat terhadap keberadaan TPA juga menjadi persoalan serius. Salah satu teroboson yang dilakukan adalah menerapkan konsep TPA regional. Guna mendukung kebijakan tersebut, diperlukan standar nasional pemilihan lokasi TPA regional. Hal ini dikarenakan belum adanya SNI tata cara pemiliihan lokasi TPA regional, sedangkan  SNI 03-3241-1994  tentang Tata Cara Pemilihan Lokasi Tempat Pembuangan Akhir Sampah, lebih sesuai berlaku untuk pemilihan TPA skala kota. Metodologi penelitian dilakukan melalui penelusuran literatur tentang kebijakan dan peraturan perundangan, kajian terdahulu, kuesioner, wawancara, diskusi teknis dan observasi lapangan terhadap rencana pengelolaan TPA regional. Analisis data dilakukan secara kualitatif untuk merumuskan kriteria dalam pemilihan lokasi TPA regional. Berdasarkan hasil analisis, disimpulkan beberapa kriteria penetapan dalam pemilihan TPA regional antara lain perlunya kebijakan antar daerah menyangkut integritas dengan tata ruang antar daerah, potensi pencemaran antar daerah, dukungan, aspek penerimaan masyarakat, skala ekonomis baik dalam tingkat pengelolaan dan pengangkutan sampah, serta dokumen pendukung seperti Studi Kelayakan dan Analisis Dampak Lingkungan.Kata kunci: Standar, Pemilihan lokasi, Tempat Pemrosesan Akhir, Sampah, Regional

Abstract

This research aimed to compare the productivity of GPS strains, namely Ross, Cobb, Hubbard, and Indian River in hens and males at 21 weeks of age. The research data was obtained from the results of an audit of the breeding company by the Directorate General of Livestock and Animal Health, Ministry of Agriculture, from November 2022 to March 2023. The results showed that the comparison of hen productivity in the four strains, namely (1) the Indian River strain had a high body weight compared to other strains, (2) the Hubbard strain has a higher depletion rate than the other strains, but this depletion rate does not reflect bad or bad genetics, but it reflects a high degree of selection, and (3) the Indian River strain has a higher uniformity level than other strains. The productivity of roosters is (1) the Indian River strain has a high body weight compared to other strains, (2) the Indian River strain has a higher depletion rate than the other strains, however, this depletion rate does not reflect bad or bad genetics, but it reflects high selection rate, and (3) Indian River strain has a higher uniformity level than other strains.

Abstract

The production performance of GPS on Cobb, Indian River, and Hubbard strains has not been well studied. This study aimed to compare the production performance between female GPS strains at 24 weeks of age and the standards set by each principal. This research was conducted from November 2022 to March 2023. The results showed a significant difference in most production performance between GPS strains at 24 weeks of age by each strain. Significant differences were observed for body weight, feed consumption, depletion and uniformity. As for comparing the production performance between the GPS strains and the standards set by the principal, there were also significant differences, and several performance parameters exceeded the standards. This result was influenced by different farming management patterns from each company adapting to actual conditions in the field.

Abstract

This study aims to compare the performance of broiler GPS flocks from 4 GPS strains in Indonesia (Cobb, Ross, Indian River, Hubbard). This research was conducted from November 2022 to March 2023. Data were collected from some breeding companies' audit results conducted by the Directorate General of Livestock and Animal Health. The results showed that the broiler GPS flock performance in the young age group showed a significance value of <0.05, and there was a significant difference in the HDP variable indicator. The average HDP weight for the Ross, Cobb, Indian River, and Hubbard GPS strains was 78.05±3.28, 74.00±3.30, 78.99±3.37 and 75.85±3.61, respectively. The average egg and hatchling weight was also significantly different among each strain, but only on the variable factor of the breeding company. There were no significant differences among the strain factor variables and primary product variables, such as the average number of DOC PS per hen by breeding company and strain. On average, a female GPS line in the young age group period for the Ross, Cobb, Indian River, and Hubbard strains produced 15.14 ± 2.2, 14.92 ± 4.6, 15.35 ±1.47, and 13.78 DOC, respectively. There is no mutual interaction between the performance of HDP flocks, egg weight, and hatching weight of DOC PS from variable factors of the breeding companies with each strain. Factorial interactions only occur in the primary product variable, meaning each broiler GPS strain reared by each breeder company in Indonesia has different performances.

Abstract

Production performance research was carried out on three Grand Parent Stock (GPS) broiler strains, namely Indian River, Ross and Cobb. The data was obtained from the results of production performance audits of broiler GPS breeders during the laying period of 25 – 65 weeks. Variables measured include laying lifeability, egg/hen house production, rate peak production/hen house, hatching egg/hen house production, fertility, hatchibilty, and saleable chick/henhouse. Data were analyzed quantitatively using t-test, analysis of variance (Anova) and Duncan. This study showed that the Indian river strain had higher production characteristics in terms of vitality, egg production, peak production, hatching egg production, and saleable chicks. Ross strains have higher production characteristics at rates of peak production, fertility, hatchability, and saleable chicks. The cobb strain has the lowest production performance compared to the other strains. Comparison between the strains and the principle standard shows that the actual hatchability and saleable chicks were lower than the standard in the Indian Rivers strain. The Ross strain had an actual value greater than the standard for fertility, hatchability and saleable chicks. Whereas the actual values for the Cobb strain for viability, egg production, peak production, hatching egg production, and saleable chicks were lower than the standard.

Abstract

The aim of this study was to examine the preservation of sentul crossbreed chicken semen in ringer lactate egg yolk diluent supplemented with various monosaccharide. Semen was collected from three roosters using massage method. Immediately after collection, the semen was evaluated macroscopically and microscopically. Semen with more than 70% motility was divided into four tubes. Each of them diluted with ringer lactate egg yolk glucose (RLEYG), ringer lactate egg yolk fructose (RLEYF), ringer lactate egg yolk xylose (RLEYX) and ringer lactate egg yolk mannose (RLEYM). Semen was stored in refrigerator (5o C) for sixty hours and evaluated every twelve hours for spermatozoa motility and viability. Results showed that no significant difference (P0.05) among diluents used on spermatozoa quality parameters after dilution and during preservation. Semen quality decrease during storage and at sixty hours of storage, the motility and viability of spermatozoa ranging from 48.332.56 to 55.422.26% and 58.592.87 to 64.832.42%, respectively. This research conclude that glucose, fructose, xylose and mannose can be used as energy source for roosters semen during preservation.

Abstract

Chicken eggs are the most widely consumed poultry product. Eggs have high protein value and are affordable for the public. Demand for local chicken eggs continues to increase every year. Merawang chicken and Arabian chicken are local Indonesian chickens. It is hoped that crossing the two chickens will produce superior offspring in egg production. The research was conducted to evaluate egg production in local chickens of the merawangarab cross with different genetic compositions of the merawang (M), namely 25% M, 50% M, 62.5% M, and 75% M, totaling 31 birds consisting of 21 adult females and 10 males. This research used a randomized block design (RAK). Egg production has achieved quite good results. The genetic composition affected egg index (P<0.05), but egg weight, hen day production, and feed conversion were the same. The four types of merawangarab chickens have the potential to be local egg-producing chickens. The egg production performance of 25%M, 50%M, 62.5%M, and 75%M was the same and all four could be developed as local laying hens.

Abstract

Salah satu permasalahan dalam pengembangan kegiatan perekonomian di kawasan pantai atau pesisir adalah pengelolaan sampah. Pengelolaan sampah di kawasan pesisir ini masih menjadi grey area, belum ada peraturan yang jelas tentang tugas dan tanggung jawab pengelola sampah pesisir sehingga pengelolaan belum berjalan efektif. Terdapat dua jenis sampah di kawasan pantai yaitu sampah dari aktivitas wisata dan sampah bawaan dari laut. Metode penelitian secara kualitatif dan kuantitatif melalui survey, observasi dan wawancara ke Instansi Pemerintah, masyarakat dan LSM . Aspek yang dikaji adalah aspek teknis operasional pewadahan, pengumpulan, pengangkutan, pengolahan, pemrosesan akhir, aspek kelembagaan, pembiayaan dan peraturan. Lokasi kajian di Kabupaten Pangandaran, Kabupaten Lombok Barat , Kabupaten Lombok Utara dan Pulau Seribu, DKI Jakarta. Sedangkan data primer dilakukan sampling timbulan, komposisi sampah di Pulau Untung Jawa Kepulauan Seribu. Sampling komposisi sampah menggunakan metode uji komposisi sampah berdasar SNI 19-3964 - 1994 tentang Metode Pengambilan dan Pengukuran Sampel Timbulan Sampah dan Komposisi Sampah dan komposisi sampah berdasar IPCC (Intergovernmental Panel on Climate Change), 2006. Pengelolaan sampah di pantai dan kepulauan di daerah studi umumnya berupa pewadahan, pengumpulan dan pengangkutan belum berbasis 3 R. (Reduce, Reuse, Recycle). Pengelolaan sampah di kepulauan hanya mengandalkan penimbunan di pulau dan pengangkutan yang dilakukan oleh kapal pengangkut sampah ke TPA. Sampah pantai terdiri atas sampah dari daratan yang timbul akibat aktivitas sekitar pantai yang jumlahnya tergantung pada jumlah pengunjung, jenis fasilitas penunjang, seperti hotel/penginapan, restoran, dan sampah bawaan dari laut yang dipengaruhi musim. Hasil sampling sampah di Pulau Untung Jawa pada hari kerja adalah sebesar 5,06 m3/hari dan pada akhir pekan sebesar 5,79 m3/hari. Sementara timbulan sampah bawaan laut dengan rata – rata timbulan sampah bawaan laut adalah 7,67 m3/hari. Sampah di daratan didominasi sampah organik (47-66) %. sedangkan sampah bawaan umumnya didominasi an organik 64,74%.
