The method used in this study is a quantitative research method. The results showed that the highest efficiency of PLTU Unit 1 was at 93.3% with an output power of 5.8 MW and an input power of 6.21 MW, while the lowest was at 83.9% with an output power of 5.5 MW and a power 6.55 MW input. The highest efficiency of PLTU Unit 2 is at 95.7% with an output power of 5.5 MW and an input power of 5.75 MW, while the lowest is at 61.03% with an output power of 3.3 MW and an input power of 5.41. MW. Meanwhile, the transformer life for Unit 1 PLTU Sumbawa Barat is 0.0469 hours/day with an average load of 5.8 MW, while for Unit 2 it is 0.0311 hours/day with an average load of 5.2 MW. The size of the loss of life of the transformer depends on the given load, the greater the load, the greater the loss of life. In this case, the load for Unit 1 is higher than for Unit 2, so it can be seen that the life loss of the Unit 2 transformer is smaller. While the optimal load on the PLTU is in the position of 80-85% of its capacity. The results of this study are expected to be a material consideration for the Sumbawa power plant to better distribute and optimize the load so that there is no imbalance between the transformer capacity and the power produced and perform routine transformer maintenance to reduce losses that occur.</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Ilham Bayu Tiasmoro, Wirentake, Paris Ali Topan https://jurnal.uts.ac.id/index.php/Tambora/article/view/1106 PENGARUH PUTARAN PULLY (RPM) DAN TEKANAN TERHADAP PRODUKTIVITAS MESIN PEMECAH BIJI KEMIRI 2021-07-22T14:17:09+07:00 Mietra Anggara mietra.anggara@uts.ac.id Aburijal Jibril jaburijal@gmail.com <p>Candlenut is a spice that is used as an ingredient in the manufacturing process of the food and cosmetic industry, the obstacles faced in breaking the candlenut shell are that the time and energy required is still too large so that the splitting of the candlenut shell is less efficient and there are still many farmers who still use traditional candlenut crackers. with a driving force in the form of human power. In addition, the results of the quality of the candlenut cracking are not good because there are still many broken hazelnut seeds after the process of breaking the candlenut shell. These constraints add to the time, cost and effort in the process of breaking candlenut manually. From some of the constraints that have been described, there is an idea to conduct research to find out how the rotation of the candlenut crusher influences the pressure according to the needs and optimizes the rotation variation of the candlenut crusher to produce whole candlenuts. The research method used is rotational variation (10 RPM, 20 RPM, and 27 RPM) to pressure 24.928 /????2, 21.952 /????2 and 19.286 /????2 with three treatments and each treatment combination was repeated three times. The parameters of this research are the percentage of whole, split, crushed and unbroken candlenut. The results of this study indicate that variations in rotation and pressure affect the percentage yield of candlenut seeds. The average value of the right rotation to break candlenut seeds with a beating pully A is 20 rpm with a pressure of 24.928 N/m2 to get an average of 60% intact, 20% halved, 0% crushed and 20% unbroken. At the right rotation of the pulley B, which is at 20 Rpm with a pressure of 21.952 N/m2, the average value of breaking is 60%, intact is 60%, split is 30%, destroyed is 0% and does not break is 10%. Meanwhile, at a pressure of 19.286 N/m2 for a rotation of 20 Rpm, the average value of broken, 50% intact, 0% halved, 20% crushed and 30% unbroken.</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Mietra Anggara , Aburijal Jibril https://jurnal.uts.ac.id/index.php/Tambora/article/view/1110 PERANCANGAN JARINGAN MENGGUNAKAN ROUTER SWITCH CISCO PACKET TRACER PADA KANTOR DISKOMINFOTIK PROVINSI NUSA TENGGARA BARAT 2021-07-22T14:47:04+07:00 Isnaeni Zulkarnaen mincinjr77@gmail.com Jannatun Aliyah jannatun.aliyah@uts.ac.id <p>In the current era of globalization, technological developments are increasingly advanced, therefore human resources are required to be competent in various fields.

The success of mangrove forest rehabilitation can be seen by the density of mangrove vegetation and the increase in mangrove crabs. Mangrove crab is the main commodity for farming communities because in addition to playing an important role in the mangrove ecosystem, it also has high economic value so it needs to be developed to increase people's income. This research was conducted with the aim of knowing the density of mangrove vegetation and crab density in different planting years and the effect of mangrove habitat characteristics on crab density. The research was conducted in three different planting years, namely 2003, 2005, and 2006. Each planting year consisted of a front zone, a middle zone and a back zone. In each zone a measuring plot with a size of 5 m x 5 m was made to collect data on vegetation density, temperature, mud thickness, salinity, acidity, and dissolved oxygen (DO). Then in the 5 m x 5 m plot, a 1 m x 1 m plot was made to collect data on the number of crabs. Data analysis used regression equation and ANOVA difference test. The results showed that the highest vegetation density was in the back zone of the 2006 planting year with a density of 2160 individuals/ha, while the highest density of crabs was in the 2005 planting year with a density of 12111.11 individuals/ha. Regression analysis showed the effect of temperature, mud thickness and salinity variables on crab density with the equation Y = 3.447 - 0.044X1 - 0.009X2 - 0.230X3 with R = 0.809. In the different ANOVA test, only the thickness of the mud had a significant difference at three years of planting (0.00 &lt; 0.05).</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Roni Haposan Sipayung https://jurnal.uts.ac.id/index.php/Tambora/article/view/1117 INOVASI LAYANAN PERSIAPAN PERSALINAN (EDUKASI DAN SENAM HAMIL) PADA IBU HAMIL DI WILAYAH KERJA UPT PUSKESMAS ALAS BARAT KABUPATEN SUMBAWA 2021-07-23T09:41:16+07:00 Fitri Setianingsih fitrisetyaningsihsumbawa1@gmail.com Ayuning Atmasari ayuning.atmasari@uts.ac.id Taryono taryonojogja1465@gmail.com <p>The labor process is influenced by three factors, namely Passage (birth canal), Passanger (fetus), Power (strength). Childbirth can run normally if all three factors are met properly. In addition, there are other factors that affect the delivery process, namely psychological and helper. Maternal Mortality Rate (MMR) can be reduced by various efforts, both promotive and preventive, by providing education in preparation for childbirth. This education can be an alternative for pregnant women to find out the extent of maternal and fetal development, increase maternal independence and train coping management for maternal stressors. Pregnancy exercise is a form of coping method that can avoid the occurrence of physical stress due to pregnancy, such as reducing leg and back cramps, increasing the mother's ability to adapt to changes in her body. This study aims to identify the effect of labor preparation services (pregnancy education and exercise) on the preparation for delivery of pregnant women in the working area of ??the UPT Puskesmas Alas Barat. Pre-experimental research design with one group pretest-post test design. The instrument used for data collection is a questionnaire. Testing the instrument using the product moment person validity test and reliability test. The analysis used is simple linear regression with the number of respondents as many as 102 pregnant women. The results showed that the regression significance value of the delivery preparation service variable (pregnancy education and exercise) on the preparation for delivery of pregnant women was 0.000 or less than 0.05. The hypothesis which states that delivery preparation services (pregnancy education and exercise) has an effect on preparation for delivery of pregnant women (accepted). Based on the results of this study, it can be suggested that pregnant women play an active role in participating in activities during pregnancy so that mothers have knowledge about the needs during pregnancy, especially preparation for childbirth so as to minimize emergencies to the mother and fetus during the delivery process.</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Fitri Setianingsih, Ayuning Atmasari, Taryono https://jurnal.uts.ac.id/index.php/Tambora/article/view/1122 PENGARUH PSIKOLOGI REKAYASA TATA RUANG KERJA TERHADAP MOTIVASI KERJA TENAGA KEPENDIDIKAN UNIVERSITAS TEKNOLOGI SUMBAWA 2021-07-23T10:06:27+07:00 Lana Zakiya Hanifa lanahanifa98@gmail.com Fitra Hasri Rosandi fitrah.hasri.rosadi@uts.ac.id <p>Sumbawa University of Technology certainly has goals that must be achieved.

The ultrasonic testing method has several advantages, namely it can be used to analyze the position of the defect in the object, both the depth of the defect and the dimensions of the defect, and it is an environmentally friendly method. Physical defects that are in solid objects of course cannot be known from direct vision so it is necessary to carry out an inspection of an object to see whether or not there are defects that occur in solid objects. Ultrasonic testing of the results of FCAW welding on the foundation of the ship's engine. FCAW welding is applied to the foundation with two types of welding positions, namely the overhead position coded P1 and the horizontal position coded P2. The test was carried out using a wave frequency of 4 MHz and using a 0° probe for analysis of defects in the area around the weld metal and a 70° probe for analysis of the weld metal. The tests were carried out using the ASME section V and ASTM E164 standards as the standard for determining defects. The test results at the P1 welding position found two types of defects, namely incomplete fusion defects with five welding points with the longest defect length of 40mm and porosity defects with two points with the longest defect length of 30mm. While the results of ultrasonic testing at the P2 welding position found two types of defects, namely slag inclusion defects with a defect length of 35mm and incomplete penetration defects with a defect length of 20 mm. The conclusion of ultrasonic testing is that the difference in welding positions is that the welding position greatly affects the quality of the welding results. The defects resulting from the welding position also vary.</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Fauzi Widyawati, Lino Marano https://jurnal.uts.ac.id/index.php/Tambora/article/view/1126 ANALISIS PENGARUH PAPARAN FISIK PADA SAMPEL GIGI TERHADAP HASIL KUANTIFIKASI DNA FORENSIK MENGGUNAKAN METODE KIT PURIFIKASI DNA KOMERSIAL 2021-07-23T10:39:05+07:00 Septi Arini septi020ftbuts@gmail.com Arief Budi Witarto Witarto@gmail.com Setia Betaria Aritonang setiabetaria@yahoo.com <p>Physical exposure to biological samples has an enormous influence on the results of forensic DNA analysis. The lack of molecular research on the effect of physical exposure on dental samples is the reason for the need for further research. This study aims to determine the effect of physical exposure on dental samples on the results of forensic DNA quantification. The parameter used is the concentration value of isolated DNA obtained from real time PCR analysis. The use of real time PCR allows the detection and quantification of specific sequences of DNA samples at the same time to be analyzed. The dental samples used were obtained from different individuals. Teeth are used as identification media because teeth are the hardest part of the body and are chemically the most stable and most resistant to degradation and decomposition. The method in this study is to give three types of treatment to the tested samples in the form of sea water immersion, river water immersion and exposure to free air at room temperature with each treatment consisting of three test samples. All samples were extracted using a Commercial DNA purification KIT with a reagent in the form of a Qiagen KIT (QIAamp® DNA Investigator) then a quantification process was carried out to see the value of the DNA concentration of each sample using real time PCR. The results of DNA quantification of dental samples from each treatment showed that the highest sample concentration value was based on the average of each treatment, namely samples with treatments exposed to free air at room temperature with a concentration value of 1.34 ng/µl, followed by samples soaked using river water with a concentration value of 0.15 ng/µl, while the sample with the lowest concentration is shown by a sample treated with seawater immersion with a concentration value of 0.10 ng/µl. Physical exposure in the form of exposure to free air, exposure to river water and exposure to sea water on dental samples, gave a not too significant effect on the results of DNA quantification produced.</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Septi Arini, Arief Budi Witarto, Setia Betaria Aritonang https://jurnal.uts.ac.id/index.php/Tambora/article/view/1127 PENGARUH AGENCY COST, RETURN ON EQUITY (ROE), DAN FREE CASH FLOW TERHADAP DIVIDEND PAYOUT RATIO PADA PERUSAHAAN MANUFAKTUR YANG TERDAFTAR DI BEI PERIODE 2010-2019 2021-07-23T10:43:49+07:00 Siti Sarah Hasibuan sitisarahhasibuan99@gmail.com Lukmanul Hakim lukmanul.hakim@uts.ac.id <p>The dividend of a company is always a concern for shareholders to invest.

The wood used by the furniture industry in Indonesia reaches 2.6 million m3 per year. The waste generated reached 54.24% of the total production. Sawmill waste generated as much as 1.4 million m3 per year. Based on field observations in several furniture industries in the Sumbawa Region, most industries produce sawdust waste that has not been used optimally, so that sawdust waste accumulates in the soil and decomposes which can trigger environmental pollution and water pollution. Teak sawdust waste has a high cellulose content so it plays an important role as a reinforcement raw material in the manufacture of particle composites. In this study using the hand lay up method of making composite particles by utilizing waste teak sawdust as raw material for reinforcement and epoxy matrix with volume variations of 30:70%, 40:60%, 50:50%, 60:40%, 70:30. %, to obtain quality composite characteristics. Water absorption obtained 14%, each composite specimen has met the standard of SNI 03-2105-2006. The results of physical tests on the water absorption of particleboard composites were the lowest at 0.48% at 30% powder volume with 24 hours immersion due to the wood powder being mixed and bonded evenly by the matrix so as to reduce voids, while the highest yield was 9.41% in 70% volume is due to the matrix not being able to bind evenly, causing voids to occur. It can be concluded that the increasing volume of powder and the length of time of immersion, the greater the percentage value of water absorption produced.</p> 2021-07-21T00:00:00+07:00 Copyright (c) 2021 Rita Desiasni, Rico Chandra, Fauzi Widyawati https://jurnal.uts.ac.id/index.php/Tambora/article/view/1129 INOVASI PEMBELAJARAN BLENDED LEARNING DENGAN METODE PROJECT BASED LEARNING TERHADAP MOTIVASI, MINAT DAN HASIL BELAJAR SISWA DI MASA PANDEMI COVID-19 2021-07-23T11:06:04+07:00 lilis suryani lilisumusahid@gmail.com Tri Susilawati tri.susilawati@uts.ac.id Harjito harjito@uts.ac.id <p>This study aims to: (1) find out how big the relationship between the application of blended learning innovations with project based learning methods on student learning motivation (2) find out how big the relationship between the application of blended learning innovations with project based learning methods on student learning outcomes (3) Knowing how big the relationship between the application of blended learning innovation and project based learning method on students' interest in learning (4) Knowing how big the relationship between the application of blended learning innovation and project based learning method on students' interest and motivation.
