Experiments on natural convection in water-cooled ribbed channels with different aspect ratios
No full textNatural convection heat transfer in vertical ribbed channels, using water as working fluid, has been experimentally studied. The investigation encompassed a large range of the channel aspect ratio, defined as the ratio between channel spacing and channel height, while the wall-to-fluid temperature difference was kept fixed. The measurement of local heat transfer coefficient was facilitated by a non-intrusive diagnostic tool, the schlieren technique, whose use for the quantitative study of liquid flows is rarely documented in the literature. Results provided an insight into the nature of free convection heat transfer from ribbed channels, whose geometry is significant in such several engineering devices as electronic equipment. It was found that a general reduction of heat transfer performance, relative to that of a flat vertical surface or a smooth vertical channel, was induced by the presence of ribs, within the range of the parameters investigated. Local and heat transfer characteristics were sensitive to changes in interplate spacing for small channel aspect ratios. Experimental data, recast in dimensionless form, were in excellent agreement with those obtained by this author in a previous research performed for aircooled channels, using the same experimental technique, the same geometric parameters of the ribbed surface, and a similar Rayleigh number

PENGGUNAAN NAMA DAERAH SEBAGAI TANDA PEMBEDA DALAM SUATU PRODUK
Get PDFSuatu tanda yang menjadi milik umum tidak dapat didaftarkan/digunakan sebagai merek suatu produk. Seperti yang digunakan oleh sebuah perusahaan yang menggunakan nama daerah sebagai merek produk kopi yang diberi nama “Kopi Sumba”. Dalam Pasal 20 Undang-Undang Nomor 20 Tahun 2016 tentang Merek dan Indikasi Geografis memuat unsur-unsur yang tidak dapat didaftarkan sebagai merek. Tanda milik umum tidak dapat didaftarkan sebagai merek oleh karena tanda milik umum merupakan suatu tanda yang merepresentasikan khalayak banyak dan secara otomatis tanda tersebut tidak dapat dikuasai secara individual. Tetapi tanda milik umum dapat diterima pendaftarannya melalui rezim indikasi geografis. Menurut penulis seharusnya tanda-tanda yang sudah diketahui menjadi milik umum untuk tidak dijadikan sebagai merek suatu produk oleh karena bertentangan dengan prinsip dalam hukum merek dan indikasi geografis.
A sign that has become a public property cannot be registered as a trademark. This article discusses a case in which the name of “Kopi Sumba” is used as a coffee brand product deriving the name of a region ‘Sumba’ by a company. Accordance with Article 20 of Law Number 20 of 2016 concerning Trademarks and Geographical Indications, certain categories cannot be registered as trademarks. One of them is signs of public property, which cannot be registered as trademarks because the sign of public property is a sign representing the public, so it cannot be owned by an individual. In this article, the author argues that public signs should not be used as a trademark of a product because it is against the principles in trademark law and geographical indications

Strategies to enhance efficiency of microbial protein production in cattle consuming tropical forages
No full textMicrobial crude protein (MCP) is the main source of protein supplied to ruminants. Several studies report that the efficiency of MCP production (eMCP) from tropical forages is low due to low rumen degradable protein (RDP) content. The studies reported in this thesis determined the eMCP from tropical forages varying in crude protein (CP) and dry matter digestibility (DMD), examined strategies to increase eMCP and the possible practical methods of application under extensive cattle production systems. This was done through four metabolism experiments, one rate of digestion experiment and a preference test experiment. In Experiment 1, the eMCP of 3 tropical forages (speargrass (Heteropogon contortus), Mitchell grass (Astrebla spp) and pangola grass (Digitaria eriantha)), and temperate ryegrass (Lolium multiflorum cultivar aristocrat) was measured. All tropical forages were associated with low eMCP (102 - 110 g MCP/kg digestible organic matter (DOM)) due to low CP and RDP content. The RDP content of the tropical forages ranged from 43 - 103 g RDP/kg DOM compared to 214 g RDP/kg DOM in ryegrass. Retention time of Cr-EDTA and Ytterbium in the rumen ranged from 13 - 34 and 29 - 59 h for tropical forages respectively, compared to 10.2 and 13.2 h for ryegrass. In Experiment 2, the rate of digestion of speargrass, Mitchell grass and ryegrass varied when incubated in the rumen of steers consuming speargrass hay (1.8% CP). Addition of a variety of nitrogen supplements; urea-ammonium sulphate (US), US plus branch chain amino acids (leucine, isoleucine and valine) plus phenylalanine (USAA), casein, cottonseed meal (CSM), yeast and Chlorella (Chlorella pyrenoidea) algae to supply approximately 170 g RDP/kg DOM improved the rate of digestion of all three substrates. However, there was no difference in rate of digestion of the three substrates between the different nitrogen supplements. In Experiments 3 and 4, steers fed medium quality pangola grass hay (9.9% CP and 61% DMD) or low quality Mitchell grass hay (4.5% CP and 41% DMD) were supplemented with US, casein and USAA. US was provided at 130, 170, 210 and 250 g RDP/kg DOM. The USAA treatment was provided at a RDP/DOM of 170 with US and then amino acids (USAA) were provided in the same ratio and level as the amino acids in the casein treatment at 130, 170, 250 and 300 g RDP/kg DOM. Increased RDP intake from all supplements increased the rumen ammonia-N concentration for both hays. The molar percentage of branch chain fatty acids (BCFA) increased 3 - 4 fold (6.6% of total VFA) above control with increasing intake of USAA or casein supplements for both hays. However, eMCP did not increase in response to increasing RDP intake from either supplement for both hays. The RDP supplementation also had no effect on intake, rate of digestion and retention time of Cr-EDTA in the rumen. In Experiment 5, steers fed Mitchell grass hay (3.8% CP and 44% DMD) were supplemented with US and Spirulina (Spirulina platensis) algae. The US was supplied to provide 90, 130, 170 and 210 g RDP/kg DOM and the Spirulina supplied to provide 90, 130, 170 and 290 g RDP/kg DOM. Increased RDP intake from US and Spirulina was associated with linear and quadratic increases in eMCP respectively. The eMCP at the highest level of US (93 g MCP/kg DOM) was below the minimum feeding standards value of 130 g MCP/kg DOM, whilst the highest level of Spirulina reached the higher end of the feeding standards (166 g MCP/kg DOM). Increasing RDP intake resulted in increased hay DM intake and total DOM intake, which were both higher for the Spirulina than the US supplement (24.5 vs.18.5 g DM/kg W/d and 11.9 vs. 7.6 g DOM/kg W/d). The retention time of Cr-EDTA and lignin in the rumen decreased with increasing RDP intake and were both shorter with Spirulina compared with US supplementation (15 vs. 21 h for Cr-EDTA; 45 vs. 56 h for lignin). In addition, Spirulina increased the BCFA concentration to 4.2% of total VFA. In Experiment 6, four different concentrations of Spirulina solution were offered to steers fed restricted amounts (14 g DM/kg W/d) of pangola hay (3.4% CP). Drinking water containing Spirulina was highly preferred and had no deleterious effect on water or hay intake. Steers strongly preferred Spirulina solution to water, when offered both solutions. Approximately 20.5% of imbibed water by-passed the rumen, which was not influenced by the Spirulina concentration in the drinking water. It may be concluded that RDP is the primary factor affecting eMCP. High eMCP was associated with low retention time of water in the rumen and high intake. Once RDP is not limiting eMCP, a source of RDP rich in true protein, nucleic acids, fatty acids, vitamins and minerals, such as Spirulina algae, may be required for cattle fed low quality tropical hay to achieve the maximum eMCP reported in the feeding standards
KOMPARASI TANDA KEAGAMAAN DALAM FILM AJARI AKU ISLAM BERDASARKAN PANDANGAN SEMIOTIKA PEIRCE
Get PDFABSTRACT
Indonesia as a compound country has a lot of differences of culture especially in the matter of beliefs. This phenomenon may occur some conflicts including interfaith love prohibition. Ajari Aku Islam has been represented a conflict of interfaith love prohibition in the case between Islam and Confucius. In order to compare the differences of Islam and Confucius, the author employs Charles Sanders Peirce communication semiotic theory. The comparison of these two religion will be begun by marking the culture and religion signs that has been shown in the movie Ajari Aku Islam. The form of the data is verbal signs and visual signs. Then, the signs will be divided into three categories consist of icon, symbol, and index. Lastly, the divided signs will be analyzed with Peirce’s semiotic triadic process. The analyses have found some differences between Islam and Confucius especially in term of the place of praying, the tools used in praying, and the way of praying. Besides, the author also found some culture differences consists of the way of dressing and the way of speaking.
Keywords: Islam, Confucius, Semiotic, Signs
ABSTRAK
Indonesia sebagai negara majemuk memiliki begitu banyak perbedaan budaya khususnya pada masalah kepercayaan. Fenomena ini mampu memunculkan konflik-konflik termasuk larangan cinta beda agama. Film Ajari Aku Islam telah menggambarkan sebuah konflik cinta beda agama yakni antara agama Konghucu dan Islam. Dalam membandingkan perbedaan antara agama Islam dan Konghucu, penulis menggunakan teori semiotika komunikasi Charles Sanders Peirce. Analisis perbandingan antara agama Islam dan Konghucu akan dimulai dengan menandai tanda-tanda keagamaan dan kebudayaan yang diperlihatkan dalam film Ajari Aku Islam. Data yang digunakan merupakan tanda verbal dan tanda visual. Kemudian, tanda-tanda tersebut akan dibagi menjadi tiga kategori yakni ikon, simbol, dan indeks. Terakhir, tanda-tanda tersebut akan dianalisis menggunakan proses semiotika pada segitiga triadik Peirce. Hasil analisis menemukan beberapa perbedaan antara agama Islam dan Konghucu, khususnya pada beberapa elemen diantaranya seperti tempat ibadah, media peribadatan, dan cara beribadah. Selain itu, penulis juga menemukan beberapa kebudayaan yang berbeda seperti cara berpakaian dan cara berbicara.

Incidence and Control of Worm Burdens in Bali Bulls Fed Forage Tree Legumes in West Nusa Tenggara
Get PDFBali cattle are the predominant domestic cattle raised in smallholder systems in eastern Indonesia. They are characterised by low growth rates partly due to genetic factors but largely due to insufficient and/or poor quality feed and management. Internal parasites can have severe impacts on animal production and are a common problem in eastern Indonesia due to poor hygiene and management practices. Prevalence, or the ratio of number of worm infestation occurrences, in the cattle population is high in West Nusa Tenggara. Astiti et al. (2011) reported prevalence levels of 81% in some area of Sumbawa Island and Astiti and Panjaitan (2011) found prevalence levels of 78% in some areas of Lombok Island where cattle were housed all day under cut-and-carry feeding system. There is currently no information on worm burdens in smallholder fattening enterprises as previous investigations have focused on smallholder breeding cattle.
The objectives of this study were to determine the status of internal parasite infections in Bali bulls being fattened with forage tree legumes under smallholder conditions and to observe the efficacy of current control practices. It was hypothesised that forage tree legumes may provide some control of gastrointestinal parasites if they contain condensed tannins and if leafy branches for feeding cattle are harvested from \u3e 2 m above ground level where they are unlikely to harbor parasites
Penggunaan Tanda Untuk Berdakwah Pada Akun Instagram Punk Muslim
Get PDFInstagram is a part of social media that is used to share photos and videos, both individually and in groups. With the existence of Instagram, this is utilized by the Muslim Punk community for preaching. Punk is one of the subcultures that exist in the world. As subcultural movements always voice their group's journey to society. As seen in the Muslim Punk community that synergizes and operates through the Instagram account @punkmuslim, with a goal that is no longer purely punk but punk that acknowledges their religious identity. (Islam). Instagram has become a platform for preaching for this community. The use of signs within this community has turned Instagram into a field for preaching, a space for discussion, and a place for creation for this Muslim punk community. We can see that punks, who are based on the principles of anti-establishment and rejection of submission, are actually active on social media and submit and adhere to the teachings of Islam. The purpose of this research is to interpret the signs used and played on the Instagram accounts of Muslim Punks. These signs are used by this community to preach to their followers who are not yet familiar with Islam. The method used by the author in this research is the visual analysis method. The elaboration of every existing visual form, which the author then relates to signs. This research uses observational studies on Instagram accounts. The results of this research are descriptions and interpretations of the signs used and played by the Muslim punk community for preaching.Instagram merupakan bagian dari media sosial yang difungsikan untuk berbagi foto dan video perorangan maupun kelompok.
