The Indonesian Kacang goat (Capra hircus) is fecund and is perfect for tropical countries but its production and population have not been optimised. Livestock reproductive improvement requires hormone monitoring. The enzyme-linked immunosorbent assay (ELISA) and radio-immuno assay (RIA) are required for precise progesterone quantification. To our knowledge, this is the first study to compare progesterone estimation methods in Indonesian Kacang goats and correlate them with corpus luteum size throughout an oestrus cycle standardized using oestrus synchronisation. All periods showed a high ELISA-RIA correlation. The data also showed that CL and progesterone concentrations were highly correlated until day 8 but uncorrelated thereafter. Our study found that the two methods were qualitatively similar but required different quantitative range standards. This research emphasizes that the comparison of progesterone hormone test results will differ when different assays are used and data on the range of deviation using these two methods is required.

Public transportation is considered to be able to handle several transportation problems, such as “the ancient” traffic congestion to “the contemporary” environmental impact. Rail transit, or also known as commuter rail, is one of the most important public transportation types since it could reduce effectively the traffic congestion. At this instant, service quality of commuter rail is essential to achieve the customer satisfaction. This research aims to assess the operations of commuter rail by assessing its service quality. The importance-performance and gap analysis (IPGA) based on nine criteria was applied to accomplish the objective. A case study was conducted in KRL commuter line of Jakarta Metropolitan Area which is operated by P.T. Kereta Commuter Indonesia. The result shows that the safety criterion has the highest relative importance score and the fare has the highest relative performance score. The IPGA technique then was employed to build strategies based on the relative importance and performance from the passengers’ point of view.

Penelitian ini bertujuan mempelajari gambaran ultrasonografi (USG) ovarium kambing kacang setelah penyuntikan hormon prostaglandin. Penelitian ini menggunakan enam ekor kambing kacang berumur 2-3 tahun, pernah melahirkan, dan bersiklus reproduksi normal. Pengamatan ovarium dilakukan dengan menggunakan USG selama 7 hari sebelum penyuntikan hormon prostaglandin sampai dengan ovulasi. Pengamatan ovarium dilakukan setiap hari dan diintensifkan setiap 12 jam menjelang ovulasi. Pengamatan ovarium terdiri atas folikel dan korpus luteum (CL). Pengamatan visualisasi respons berahi dilakukan sebelum dan setelah penyuntikan hormon prostaglandin. Hasil penelitian menunjukkan bahwa ovarium memperlihatkan dinamika folikel dan CL. Dinamika folikel dikarakteristikkan dengan gelombang folikel. Interval antara penyuntikan hormon prostaglandin sampai dengan ovulasi ialah 52,8±6,6 jam dengan nilai rataan diameter folikel ovulasi 5,7±0,7 mm. Visualisasi respons berahi pada kambing kacang tidak bermakna baik sebelum dan setelah penyuntikan hormon prostaglandin.

Spontaneous and ragi fermentations are the most common methods in producing traditional fermented foods in Indonesia. The present work aimed to compare the impacts of spontaneous and ragi fermentations on cereal flour properties. Three kinds of cereal, namely whole sorghum, waxy coix, and white maize were processed into flours through spontaneous fermentation, ragi fermentation, and without fermentation (control). Fermentation methods were adopted from the Indonesian traditional processing methods. Cereal grains were immersed for 72 h in distilled water (1:2 w/v) for spontaneous fermentation, and in 1% ragi tapai solution (1:2 w/v) for ragi fermentation. Meanwhile, native flour (without fermentation) was produced by grounding and sieving the cereal grains. Results showed that both fermentation techniques significantly altered the physical properties of cereal flours, as indicated by the increase in lightness index and decrease in water-binding capacity and viscosity. However, cereal flours' chemical and functional properties remain unchanged during fermentation, except for lipid and amylose. Spontaneous fermentation significantly resulted in the lowest lipid content of cereal flours, while ragi fermentation resulted in the lowest amylose content of cereal flours. Sorghum flour generally showed better nutritional properties among the examined cereal flours, especially lipid, protein, and dietary fibre. Meanwhile, waxy coix and white maize flours had the highest folate. [ABSTRACT FROM AUTHOR]

llmu komunikasi merupakan ilmu terapan. Artinya ia menerapkan asas-osas ilmiah teori, generalisasi, dan penemuan ilmiah dari empat ilmu sosial dasar yang telah melandasinya. Tidak bisa dibayangkan seorang ilmuwan atau pakar komunikasi yang bergerak pada dataran praktis sekalipun,jika ia tidak memahami atau menguasai prinsip-prinsip ilmu sosial dasar, karena yang menjadi inti perhatian sehari-hari adalah perilaku manusia dan perubahan sosial. 1idak berarti bahwa sebagai ilmu terapan ia lantas menjadi pasif. ia justru harus aktif berkreasi. berinovasi, dan berimajinasi, melalui penelitian, pengembangan, dan penyebaran dalam situasi riil. Dalam hal ini ia akan dibimbing oleh masalah-masalah implementasi praktis maupun masalah-masalah konsepsional teoritik.
