PARAMETER GENETIK DAN ANALISIS HUBUNGAN ANTAR SIFAT PADA GENERASI F2 PADI HASIL PERSILANGAN INPARI 31 X BASMATI DELTA 9
No full textOne of the goals of Indonesia's rice improvement program is to develop high-yielding varieties with long and slender rice grains. This study aimed to estimate the genetic parameters affecting gene action, amount of gene action, number of gene control, magnitude of genetic variability, heritability, genetic advance, and correlations between yield components and yield of Inpari 31 x Basmati Delta 9 in the F2 generation. The experiment was carried out at an experimental farm at the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, Central Java, Indonesia. The genetic material used was seed from an F2 population crossed between Inpari 31 and Basmati Delta 9 with the two parental genotypes. Estimates of skewness, kurtosis, genetic variability, heritability, genetic advance, correlations between traits and path analysis were calculated for yield and yield component traits. Results show that additive and complementary epistatic action control yield-related and yield traits. Yield-related trait components and yield are controlled by a monogenic or polygenic genes, depending on the observed trait. Wide genetic variability, high broad sense heritability and high genetic advance were found in the number of productive tillers per hill and grain weight per panicle. These traits show a significant positive correlation and have a direct effect on the yield; therefore, they can be used as traits in the selection to produce high-yielding rice, with long rice sizes and slender shapes.

T0 was the control diet while T2, T4, T6, and T8 received additional 2%, 4%, 6%, and 8% moringa leaf meal, respectively. The treatment was given during pregnancy until the kit was 21 days old. Blood samples collected from rabbits does on the last day of study and evaluated for serum biochemical indices, data obtained were analysed statistically. The variables observed were cholesterol, glucose, total protein, albumin, globulin, creatinine, and urea. The results showed that cholesterol, total protein and albumin in the blood serum of rabbit doe were significantly different (P<0.05) while glucose, globulin, creatinine, and urea were similar (P>0.05) between the groups. Giving Moringa leaf meal up to 8% in biscuit diet was able to reduce cholesterol content in the blood from 75.10 mg/dl to 58.20 mg/dl. Total protein in blood serum increased from 6.94 g/dl to 8.24 g/dl. This increase in total protein seems to be influenced by a significant increase in albumin from 4.08 g/dl to 5.58 g/dl. The other variables still have values in the normal level such as controls
Community Based Tourism Model Development in a Cultural Conservation, Agro Tourism Management, and Creative Economics in Sailing Tourism Village, Tanggamus Regency
No full textThe principle of sustainable tourism development is derived from variousattractions management concepts, which is applied among others in ecotourism and tourismvillages. The tourism village is developed by exploring the potential that exists in thevillage, both natural potential, customs of the surrounding community, cultural uniqueness,and patterns of life that occur in daily life. The tourism village directly involves theparticipation of the local community as a party that is in direct contact withtourists, so that itbecomes a special concern to determine the management model by making the community asubject, not just an object. One of the tourism villages that has been active in LampungProvince is in Tanggamus Regency, namely Sailing tourism village as a weaving industrycenter of Lampung. The village offers the attractiveness ofthe process of making Lampungtapis woven cloth to the sales process. In addition, thereare also agro-tourism locations withfruit gardens as objects and waterfalls, as well as springs managed by the community. Theexistence of the Sailing tourism village, which is positioned in the middle of communitysettlements and even formed with collaboration between communities, becomes a specialdemand that the management of this area should be designed with the participation of thecommunity as tourism actors, one of which is through the concept of developing communitybased tourism (CBT) in 3 participations, namely ideas, material, and real action. Thecommunity based tourism model designed from the findings in the Sailing tourism villagehas 4 stages, namely identifying potential that can be developed into attractiveness, raisingawareness to the public as subjects and tourist objects, developing a managementorganization with the formation of organizational structures and governance documents, andimplementing tourism programs and businesses
Integrasi Pasar Daging Ayam Ras (Broiler) di Pasar Modern Indonesia
Get PDFProduction and consumption of chicken meat in Indonesia continues to increase; however, the development of broiler chicken prices at the consumer level tends to fluctuate. In addition to price fluctuations, there are risks related to chicken weight depreciation, chicken mortality, transportation costs, as well as poorly organized marketing channels and distribution patterns for broiler chickens. The distribution pattern of broiler chicken meat is closely related to market integration. Market integration is one of the characteristics of an efficient market, where strong integration means that price information at various market levels is well communicated. Therefore, a study will be conducted to assess the market integration of broiler chicken meat at the farmer and retailer levels in modern markets. The data used in this study will consist of monthly time series data for five years, from January 2018 to December 2022. The study on market integration of broiler chicken meat will employ the Index of Market Connection (IMC) analysis. Based on the IMC value of 5.242 and β2 value of 0.283, it can be concluded that the market integration of chicken meat at the Farmer and Modern Market levels is classified as weak, in the long terms.Production and consumption of chicken meat in Indonesia continues to increase; however, the development of broiler chicken prices at the consumer level tends to fluctuate.
