This city is prone to earthquake activity because it is right above the active volcano, namely Mount Gamalama. in 2012 there was an earthquake that caused severe damage to residential areas. This incident was caused by local tectonic earthquakes occurring 39 times, distant tectonic earthquakes occurring 432 times, and tectonic earthquakes being felt 5 times. It is not surprising that in the future this city will experience a tsunami as a result of the activity of Mount Gamalama because geographically this city is an archipelago city where activities between cities and districts depend on sea transportation. The purpose of this study is to model a tsunami with a height of 30 meters in the city of Ternate. Based on the results of spatial data, the impact of the tsunami occurred that almost all districts on the island of Ternate would sink. The most severe sub-districts are the sub-districts of Central Ternate City, North Ternate City and South Ternate City. Meanwhile, for the Ternate Island sub-district, the impact was not too significant.","PeriodicalId":31860,"journal":{"name":"Techno","volume":"92 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve laboratory management services, a device data collection system was developed which is contained in a web-based application, called SiDal (Laboratory Big Data System). SiDal is a subsystem of the laboratory management system at the Basic Physics Laboratory of FPMIPA UPI. The aim of developing SiDal is for laboratory services to be more effective and efficient with optimal results. Users can access tool data, tool catalog, tool status and where to store the tool. To see the success of the system, research was carried out using the Research and Development method. Trials of the application of this system were carried out at the Basic Physics Laboratory of FPMIPA UPI by conducting surveys through questionnaires and interviews. From the results of the questionnaire distributed, 68 student respondents from various generations had accessed SiDal. 98.5% of respondents agreed that the implementation of SiDal in the Basic Physics Laboratory provided an increase in laboratory management services. The results obtained will serve as an evaluation and further development of the laboratory management system.","PeriodicalId":31860,"journal":{"name":"Techno","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to observe the response of the tissue and organs of arabica coffee seedlings to adding nitrogen. Nitrogen is used in the urea fertilizer form. This research used a single factor of CRD with five replications. 4 levels were tried without urea fertilizer as a control (N1), dosage of urea fertilizer 15 g urea.plant-1 is equivalent to 6,9 g of nitrogen (N2), dosage of urea fertilizer 30 urea.plant-1 is equivalent to 13,8 g of nitrogen (N3), and dosage of urea fertilizer urea.plant-1 is equivalent to 20,7 g of nitrogen (N4). After application, the plants are incubated for 30 days to allow time for the fertilizer to be absorbed by the plants. The analysis result stated that the chlorophyll content was very significantly different, while other agronomic variables were not significantly different. Less adaptation period was thought to be the cause of the various agronomic variables being not significantly different. This is reinforced by the response that arises in plant tissue. The addition of urea fertilizer responded to the thickness of the mesophyll tissue, the size of the epidermal cells, and the regularity of the lower epidermal cells. The result of this research concluded that the response of plants to the treatment had not yet reached the organ level but was still at the tissue level.","PeriodicalId":31860,"journal":{"name":"Techno","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nutrition can be done with AB mix nutrition with a certain concentration while the frequency of water can be controlled with a microcontroller. The purpose of this study was to examine the effect of various concentrations of AB mix nutrients and the frequency of irrigation water using a microcontroller on the yield of mustard greens. This research can be useful as a source of information related to the application of microcontroller sensors in the provision of appropriate AB mix water and nutrition for farmers and practitioners. The research design consisted of two treatments, namely the concentration of AB mix and the frequency of water administration with 3 repetitions. the concentration of AB mix nutrients given consisted of three variations, namely 750 ppm (D1), 1250 ppm (D2), and 1750 ppm (D3) while the frequency variations consisted of variations of 4x water administration (F1), 8x water administration (F2), and 12x water administration (F3). The volume of water has increased by three stages from the beginning of planting to harvest. The results showed that the AB mix concentration treatment showed a significant difference to plant fresh weight but not to other parameters. The frequency of water treatment also showed the same results as the nutrient concentration treatment and there was no interaction between the frequency of water treatment and the AB mix concentration. Furthermore, the best variation is the variation of nutrition 1750 ppm and the frequency of 8x watering.","PeriodicalId":31860,"journal":{"name":"Techno","volume":"92 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, information on the adverse effects of using chitosan on plants still needs to be available. This study aims to discover the side effects of applying chitosan on the Brassica juncea. This test is done using Complete Random Design (CRD). The test is carried out by applying a solution of chitosan with five series of concentrations (0.5%, 1.5%, 2.5%, 3.5%, and 4.5%) plus control of acetic acid 1% (AA) to the upper and lower surfaces of the B. juncealeaves (old and young leaves) using a brush smooth to drip wet. The trial was repeated four times. Data was analyzed using ANOVA (Analisis of Variance). When there is a significant difference between the treatments, further tests are conducted using DMRT at a substantial level of 5%. In two week and three week B. juncea plant, the highest chlorophyll content is observed in the chitosan with a concentration of 3.5% and 0.5% with the same value of 0.74 mg/g, while the lowest concentration is at 1.5% 0.61 mg/g at the age of two weeks and 0.50 mg/g at three weeks. Using chitosan at high concentrations (2.5-4.5%) indicates phytotoxic occurrence in the leaves of two week or three week old B. juncea plants. Phytoxic indications are seen in rolling leaves, thickening, and structurally more hardinge when compared with low concentration (0.5% and 1.5%) and control treatments. It is best to pay attention to the use of concentrations of chitosan so that plants get optimal positive effects without causing adverse side effects.","PeriodicalId":31860,"journal":{"name":"Techno","volume":"61 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136132657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
