The aim of the research was to study the quality of livestock production in relation to carcass quality and body weight. The research was conducted descriptively using exploratory techniques on cattle and their products (carcasses). Research for 1 (one) month at the cattle slaughtering location in Manokwari district, namely the first slaughtering location is Transito Wosi, the second slaughtering location is Rendani and the third location is Wosi Market. Samples were obtained randomly by selecting 86 male cattle which were slaughtered with the following criteria: Age 1-2 years, Age 2-3 years, Age 3-4 years, Age 4-5 years and Age > 5 years. The results of this study indicate that the percentage of cattle slaughtered is based on age, namely 2-3 years of 67.44%, 3-4 years of 43.99%, while the highest carcass weight is in the 3-4 year age category of 162.89 ± 77. 32 kg, and the longest carcass length in the 4-5 year old cattle category was 122.40 ± 11.80 cm. Slaughter weight has a close relationship (94.72%) with carcass weight, carcass percentage and carcass length. Differences in age category had no effect on carcass weight, carcass length and carcass percentage. Body weight is strongly influenced by body length and chest circumference. It is necessary to carry out further research with observations starting from livestock rearing, feed given, livestock handling before to after slaughter, carcass quality (thickness of fat, area of rib eye veins).

Hubungan Ukuran Tubuh dengan Bobot Badan dan Bobot Karkas Bandikut (Echymipera rufescens) Di Kampung Manawi Distrik Angkaisera Kabupaten Kepulauan Yapen: The Relationship between Body Measurement and Body Weight and Carcass Weight of Bandicoot (Echymiera rufescens) in Manawi Village, Angkaisera District, Yapen Isand Regency
No full textAbstract
Bandicoot (Echypera rufescens) is an alternative source of animal protein and a source of germplasm for humans, especially local communities in Papua. These animals are obtained by hunting and/or setting traps in the community's closest habitat. The aim of this research was to determine the relationship between body measurements and body weight and carcass weight by utilizing 32 bandicoots, 16 males and 16 females, with a live weight range of 400 - 2000 grams in Yapen Island Regency, Papua. The study was conducted by using an explorative study and the data were analyzed using multiple correlations and regression. The carcass was obtained by slaughtering the head, removing the blood, and then removing the hair by burning (singeing). The average body weight of male bandicoots was 1403 grams and that of females was 598.75 grams, while the average carcass weights of males and females were 1050.06 grams and 415 grams, respectively. The average heart girth of male bandicoots is 23.03 cm and that of females is 17.81 cm, while the average body length of male and female bandicoots is 25.19 cm and 18.91 cm, respectively. The average percentage of male bandicoot carcasses was 73.99 cm and that of females was 69.22 cm. The correlation coefficient between body weight and body measurements was 0.911 while the carcass weight and body measurements were 0.901. The correlation between body weight and carcass of male bandicoots were 0.911 and 0.901. The correlation between body weight and carcass of female bandicoot were 0.702 and 0.747. The regression equation for male bandicoots to estimate body weight (BB) and carcass weight (BK) were BB = (-1705, 594+84,432 X1 +46,234X2) and (BK = -432,092 +71,545 X1 +33,127X2). The female bandicoot regression equations to estimate body weight (BB) and carcass weight (BK) were: (BB = -509,134+39,437 X1 +21,443X2) and (BK= -436,703 +31,720 X1 +15,164X2).

Scientific Reports, 9(1), (2019): 12319-019-48661-9, doi:10.1038/s41598-019-48661-9.We present observational evidence that a significant regime change occurred around the year 2000 in the formation of Warm Core Rings (WCRs) from the Gulf Stream (GS) between 75° and 55°W. The dataset for this study is a set of synoptic oceanographic charts available over the thirty-eight-year period of 1980–2017. The upward regime change shows an increase to 33 WCRs per year during 2000–2017 from an average of 18 WCRs during 1980 to 1999. A seasonal analysis confirms May-June-July as the peak time for WCR births in agreement with earlier studies. The westernmost region (75°-70°W) is least ring-productive, while the region from 65°W to 60°W is most productive. This regime shift around 2000 is detected in WCR formation for all of the four 5-degree wide sub-regions and the whole region (75°-55°W). This might be related to a reduction of the deformation radius for ring formation, allowing unstable meanders to shed more frequent rings in recent years. A number of possible factors resulting in such a regime shift related to the possible changes in reduced gravity, instability, transport of the GS, large-scale changes in the wind system and atmospheric fluxes are outlined, which suggest new research directions. The increase in WCRs has likely had an impact on the marine ecosystem since 2000, a topic worthy for future studies.The authors acknowledge financial supports from NOAA (NA11NOS0120038), NSF (OCE-0815679), SMAST and UMass Dartmouth.

Condition and Status of Shrimp Fisheries in West Papua Province: Case from Bintuni Bay Regency, Sorong City, and South Sorong Regency
No full textThe aim of this research was to determine the condition and status of shrimp fisheries in Bintuni, Sorong, and South Sorong Regency. This research was conducted from May to July 2019 in the center of the shrimp industry. Variables measured in this study include the status of shrimp fisheries, shrimp fisheries production data for 10 (ten) years, conditions of shrimp availability, size, and type of shrimp obtained through interviews using questionnaires used to obtain an overview of shrimp stock conditions in nature. Analysis of the estimation of potential shrimp resources using the surplus production method from FAO (Food Agriculture Organization). Surplus Production is based on the assumption that Catch per Unit Effort (CPUE) is a function of f (catching effort/effort) which is linear. Data analysis, it was found that the highest number of shrimp catches occurred in 2010-2015, while the status of shrimp fisheries from the maximum sustainable yield (MSY) was 10,943.1 tons per year. Based on data collected for 10 years, from 2010 to 2020, the number of shrimp catches in the waters of Bintuni Bay and South Sorong has not exceeded the value of shrimp sustainable potential. The highest shrimp catch in the waters of Bintuni Bay and South Sorong occurred in 2015, which was 5,473 tons. The utilization rate of shrimp in the waters of Bintuni Bay and South Sorong is 5,473/10,943.1 which is 50.01%, respectively. Based on calculations using the catch effort data analysis package (CEDA 3.0), the value of the catchability coefficient (q), intrinsic growth rate (r), and carrying capacity (k) are used to determine the population growth rate. In equilibrium condition, when the growth rate is equal to zero, the shrimp population is equal to a carrying capacity of 15.519,9 tons per year, respectively
PERAN TERNAK BABI SEBAGAI BIO-TILLAGE SYSTEMS PADA LAHAN KEBUN DALAM BUDAYA BERTANI MASYARAKAT ARFAK, PAPUA BARAT
No full textABSTRAKMengetahui seberapa jauh aplikasi penggunaan ternak babi dalam kebun masyarakat Arfak di Pegunungan Arfak penting untuk dipelajari karena Arfak memiliki kondisi agroekologi penting. Masyarakat Arfak memiliki kearifan dalam bertani serta memiliki hubungan yang dekat dengan ternak babi. Hasil tinjauan di lapang dan referensi menunjukkan bahwa ternak babi relatif masih digunakan pada lahan pertanian atau kebun keluarga masyarakat Arfak sebagai hewan penggembur tanah (soil dozer). Ternak babi, kebun dan masyarakat Arfak saling berinteraksi dengan memberikan peranan kepada masing-masing komponen. Kelebihan ternak babi sebagai penggembur tanah kebun biologis mampu membantu petani orang Arfak. Terdapat 7 keunggulan penggunaan ternak babi dalam kebun. Namun jumlah ternak yang dapat dimasukkan serta sejauhmana kinerja ternak babi dalam setiap luasan lahan secara ekonomis, ekologis dan sosiologis masih harus dikaji secara intensif. ABSTRACTKnowing how far the application of pig farming in Arfak people 's gardens in the Arfak Mountains is important to learn because Arfak has important agro ecological conditions, the Arfak people have wisdom in farming and have a close relationship with pigs. The results of the review in the field and references show that the pigs are relatively still used on agricultural land or Arfak people's family farms as soil dozers. Pigs and gardens and Arfak people interact with each other by providing service to each component. The advantages of pigs as biological gardeners are able to help Arfak farmers. There are 7 benefits of using pigs as bio-tillage inside Arfak household gardens. However, the number of livestock that can be included and the extent to which the performance of pigs in each area of land economically, ecologically and sociologically, must still be studied intensively. Â
A Bibliometric Analysis of Research on Indonesian Governance
No full textThis paper is a bibliometric analysis aimed at understanding and analyzing the evolution of Indonesian governance publications. SINTA and Google Scholar were used to find articles from academic journals, which were then organized in Publish or Perish and Mendeley. The year of publication, the institution or educational institution that published, the name of the publication, the name of the author of the article, and citations from the authors who published the articles on governance in Indonesia were all used to analyze 772 articles from academic journals. VOSviewer was used to visualize the collected articles. We thereby produced co-occurrence visualizations that show how the publications are related to one another. For all articles on Indonesian governance published since 2001, nine clusters of interrelationships were discovered. According to our findings, Indonesian governance research is mostly focused on efforts to achieve good governance through public services. The topic of collaboration with stakeholders outside the government, on the other hand, is still missing. As a result, we recommend that this subject be investigated further.

The definitive version was published in Journal of Geophysical Research: Oceans 125(8), (2020): e2019JC016033, doi:10.1029/2019JC016033.A census of Gulf Stream (GS) warm‐core rings (WCRs) is presented based on 38 years (1980–2017) of data. The census documents formation and demise times and locations, and formation size for all 961 WCRs formed in the study period that live for a week or more. A clear regime shift was observed around the Year 2000 and was reported by a subset of authors (Gangopadhyay et al., 2019, https://doi.org/10.1038/s41598-019-48661-9). The WCR formation over the whole region (75–55°W) increased from an average of 18 per year during Regime 1 (1980–1999) to 33 per year during Regime 2 (2000–2017). For geographic analysis formation locations were grouped in four 5° zones between 75°W and 55°W. Seasonally, WCR formations show a significant summer maxima and winter minima, a pattern that is consistent through all zones and both temporal regimes. The lifespan and size distribution show progressively more rings with higher longevity and greater size when formed to the east of 70°W. The average lifespan of the WCRs in all four zones decreased by 20–40% depending on zones and/or seasons from Regime 1 to Regime 2, while the size distribution remained unchanged across regimes. The ring footprint index, a first‐order signature of impact of the WCRs on the slope, increased significantly (26–90%) for all zones from Regime 1 to Regime 2, with the highest percent increase in Zone 2 (70–65°W). This observational study establishes critical statistical and dynamical benchmarks for validating numerical models and highlights the need for further dynamical understanding of the GS‐ring formation processes.The authors acknowledge financial support from NOAA (NA11NOS0120038), NSF (OCE‐0815679 and OCE‐1851242), and SMAST and UMass Dartmouth.

The definitive version was published in Journal of Geophysical Research: Oceans 125(10),(2020): e2020JC016507, https://doi.org/10.1029/2020JC016507.Survival of Gulf Stream (GS) warm core rings (WCRs) was investigated using a census consisting of a total of 961 rings formed during the period 1980–2017. Kaplan‐Meier survival probability and Cox hazard proportional models were used for the analysis. The survival analysis was performed for rings formed in four 5° zones between 75° W and 55° W. The radius, latitude, and distance from the shelf‐break of a WCR at formation all had a significant effect on the survival of WCRs. A pattern of higher survival was observed in WCRs formed in Zone 2 (70°–65° W) or Zone 3 (65°–60° W) and then demised in Zone 1 (75°–70° W). Survival probability of the WCRs increased to more than 70% for those formed within a latitude band from 39.5° to 41.5° N. Survival probability is reduced when the WCRs are formed near the New England Seamounts.We are grateful for financial supports from NOAA (NA11NOS0120038), NSF (OCE‐1851242), SMAST, and UMass Dartmouth.
