Perbandingan Temperatur Engine Menggunakan Water Coolant Dan Air Biasa Pada Engine Daihatsu Taruna EFI 1.6
Get PDFMobil yang digunakan untuk menempuh perjalanan yang jauh biasanya dipacu dengan kecepatan yang cukup tinggi dengan putaran mesin berkisar pada rpm 2000 dan dalam jangka waktu yang cukup lama. Agar tidak terjadi hal-hal yang tidak diinginkan akibat suhu mesin melebihi suhu normal mesin saat bekerja, maka penelitian ini perlu dilakukan. Pada penelitian ini dilakukan pengujian perbandingan laju pembuangan panas mesin antara pemakaian 100% air dengan campuran 80% air dan 20% radiator coolant dengan metode paired comparison pada rpm 2000. Dari penelitian tersebut diambil data antara lain temperatur masuk dan keluar radiator, dan volume aliran fluida radiator (Q) yang kemudian dilakukan pengolahan data untuk menentukan laju aliran massa (m), panas spesifik fluida (Cp), laju pembuangan panas radiator (q), dan pengolahan data secara statistik. Hasil pengujian terhadap campuran fluida radiator 80% air dan 20% radiator coolant menunjukkan rata – rata selisih temperatur inlet radiator dengan temperatur outlet radiator yang lebih tinggi sebesar 4,725˚C serta rata-rata laju pembuangan panas radiator yang lebih tinggi juga sebesar 8,0378 kJ/s. Kondisi ini menunjukkan pada rpm 2000, campuran 80% air dan 20% radiator coolant memiliki kemampuan penyerapan dan pembuangan panas mesin yang lebih tinggi daripada 100% air
PENGARUH KONSENTRASI EKSIPIEN PADA PEMBUATAN TABLET PENYEDAP RASA BERBAHAN BAKU KEPALA UDANG WINDU (Penaeus monodon)
Get PDFShrimp heads, which are usually discarded, are a byproduct often produced during shrimp processing. The heads of Panaeus monodon contain glutamic acid, an amino acid with the ability to impart a umami taste. The heads can be made into natural flavoring tablets through a wet granulation process. The aim of this research is to determine the concentration of fillers that affect the physical properties of tablets. To fill the shrimp head powder, amilum manihot and monohydrate lactose were added at concentrations of 5%, 10%, 15%, 20%, and 25%. Gradually, a 5% PVP was added to the mixture and kneaded until smooth. The wet granules are sieved with a 12-mesh sieve, then dried for two hours in an oven at 60 degrees Celsius. The dry granules are sieved with a 16-mesh sieve, and PEG 4000 is added at 2% of the dry granule weight. A tablet press is used to process the mixture. Then a weight uniformity, brittleness, and disintegration time test were conducted. The results show that the flavoring tablets with a 5% concentration of cassava starch as the filler have a weight uniformity of 1.4%, a brittleness of 0.7%, and a disintegration time of 6 seconds. The flavoring tablets with a 25% concentration of monohydrate lactose as the filler have weight uniformity, brittleness, and disintegration time characteristics of 0.3%, 0.2%, and 18 seconds, respectively. Based on the brittleness test results, the flavoring tablets with a 25% concentration of monohydrate lactose as the filler have the best characteristics.

The aim of this research is to analyze the influence of financial and macroeconomic ratios on the financial performance of banks listed on the BEI in 2019-2023. The data used is secondary data obtained from the official websites of the Indonesian Stock Exchange and Bank Indonesia. The sampling method was carried out using purposive sampling with 13 banks sampled during the research period. The data analysis used is multiple linear regression which consists of classic assumption tests and hypothesis tests. The research results prove that 1) Capital Adequacy Ratio has a negative and insignificant effect on Return on Assets, 2) Loan to Deposit Ratio has a negative and significant effect on Return on Assets, 3) Inflation has a negative and insignificant effect on Return on Assets, 4) BI- 7 Day Reverse Repo Rate has a positive and significant effect on Return on Assets (ROA). Simultaneous testing proves that the Capital Adequacy Ratio, Loan to Deposit Ratio, Inflation, and BI-7 Day Reverse Repo Rate have a positive and significant effect on financial performance as measured using Return on Assets (ROA) in banks listed on the BEI in 2019-2023.

DESAIN LAPANGAN PAMEDAN AHMAD YANI SEBAGAI TAMAN KOTA TANJUNGPINANG BEBASIS KEBUDAYAAN MELAYU KEPULAUAN RIAU
No full textGreen Open Space was an instrument to provide an open space for people to do some activities that can be city icons. Pamedan Ahmad Yani Field was one of the city's icons in Tanjungpinang, but the design has not implemented the local culture into its design. Local culture can be used or implemented as a site appeal. This research aims to provide a redesign of Pamedan Ahmad Yani Field as a city park using local culture in the site design. Riau Islands culture was adapted considering the site location located in Tanjungpinang, Riau Islands, which is popular with its culture and literature, Gurindam 12. Questionnaires were distributed to 93 people to gain visitors' data and their perspectives about redesigning using local culture in the site design. The concept applied in the design is Modern-Local Cultural (Moltural), which combines local culture with current design developments. This research contains a series of designs consisting of commissioning, analysis, problem definition, conceptual studies, preliminary/schematic designs, site plans, and construction documents, with the final result in the form of designs with a local cultural approach consisting of working drawings and illustrations
REDESAIN KANTOR IMIGRASI KELAS I TPI SAMARINDA PENEKANAN PADA ORGANISASI RUANG DAN GAYA ARSITEKTUR NEO VERNAKULAR
Get PDFThe Class I Immigration Office of TPI Samarinda is one of the technical implementation units of the regional office of the Ministry of Law and Human Rights of East Kalimantan. It has the duty to carry out some of the main tasks and functions of the Ministry of Law and Human Rights, namely providing travel documents and residence permits for both Indonesian citizens and foreigners, particularly in the areas of Samarinda city, Bontang, Kutai district, and Mahakam Ulu. As a public service office, the Immigration Office faces several challenges, including poorly planned spatial organization, lack of adequate photo studios, separate service areas, and unplanned space additions, all of which hinder the primary activities and functions within the office. The redesign of the Class I Immigration Office of TPI Samarinda emphasizes spatial organization and incorporates the architectural style of Neo Vernacular Dayak Kenyah. This emphasis aims to facilitate both visitors and employees in carrying out activities within the office through the application of a grid spatial organization. The application of the Neo Vernacular Dayak Kenyah architectural style includes the form, facade, and building ornaments.
 
PENGARUH PEMANFAATAN LIMBAH CANGKANG KERANG DAN LIMBAH KERAMIK SEBAGAI SUBSTITUSI AGREGAT HALUS DAN AGREGAT KASAR PADA BETON TERHADAP KUAT TEKAN BETON
Get PDFLimbah cangkang kerang dan keramik merupakan limbah yang jumlahnya cukup banyak dan sering ditemukan di Provinsi Kalimantan Timur khususnya di Kabupaten Kutai Lama.Penelitian ini dilakukan untuk mengetahui pengaruh pemanfaatan limbah berupa cangkang kerang sebagai substitusi sebagian agregat halus dan limbah keramik lantai sebagai substitusi agregat kasar terhadap kuat tekan beton.
Campuran limbah cangkang kerang dengan presentase 5% ditambah limbah keramik dengan presentase yang digunakan masing - masing adalah 13,75%, 27,5%, 41,25%, dan 54%. Pengujian material agregat kasar dan halus yang dilakukan adalah pengujian analisis saringan, kadar air, berat jenis dan penyerapan, bobot isi dan abrasi. Pengujian kuat tekan beton dilakukan pada beton umur 7, 28 dan 35 hari dengan benda uji silinder 10 x 20cm.
Hasil pengujian menunjukkan bahwa substitusi limbah cangkang kerang dan keramik mempengaruhi kekuatan tekan dan nilai slump beton. Terjadi penurunan kekuatan tekan beton campuran limbah cangkang kerang dan keramik sebesar 10,94%, 3,80% 23,60%, dan 25,88% terhadap campuran beton normal. Berdasarkan penelitian ini dapat diketahui bahwa substitusi limbah cangkang kerang sebagai substitusi sebagian agregat halus dan limbah keramik sebagai substitusi agregat kasar dengan proporsi tersebut tidak dapat menaikkan kuat tekan beton
