The measuring system is used to measure the quality of water on theriverMartapura South Kalimantan, Indonesia. The physical parameters that measured is the of water. The measuring of turbidity detected by the sensor through the light that traverse the suspended particles in water. The output signal from the sensor in from of the voltage signal is connectedwith ATMega16A-PU microcontroller viaport A0. The voltage signal output is inversely proportional to the turbidity. Theequation of sensor characteristic is obtained by comparing the measuring device with HACH DR 890 Colorimeter turbid meter gauge. The characteristic equation obtained is counted into five equations to get a small error value, where v1 = -0.0036k1 + 4.0834, v2 = -0.0024k2 + 3.9351, v3 = -0.003k3 + 4.1777, v4 = -0.0033k4 + 4.3355, v5 = -0.0034k5 + 4.4315, the five equations have different measurement ranges. The result of data measurement are displayed on the LCD 16 x 2 character and the personal computer (PC) with the Delphi.7 interface program. The advantages of personal computer (PC) interface are the data measurement result could monitor and stroge in excel and database format.

This makes vehicle users panic and think to immediately look for the nearest tire repair location. Banjarbaru City has 5 sub-districts and 12 villages, and is the center of the South Kalimantan Province administration. Given the large number of settlements, especially now that there are many housing complexes in Banjarbaru, this automatically makes the number of new roads opened by the local government. Actually this can be an opportunity for tire repair entrepreneurs to open tire repair locations in several places, because nowadays there are still very few workshops or tire repair locations in the new residential area.Location Based Service System, or better known as LBS, combines the process of a mobile service with the geographical position of its users. The important point is when the target position, where a target might be an LBS user or another entity that is incorporated in a service.

Biobriket juga mempunyai keuntungan ekonomis karena dapat diproduksi secara sederhana, memiliki nilai kalor yang tinggi. Biobriket yang dibuat berasal campuran antara bottom ash batubara dan onggok tepung tapioka. Ketersediaan bottom ash batubara onggok tepung tapioka cukup banyak di Kalimantan Selatan. Bottom ash merupakan sisa hasil pembakaran batubara di PLTU yang saat ini belum banyak di manfaatkan dan hanya dibuang sebagai limbah. Padahal bottom ash batubara ini masih mempunyai nilai kalori yang cukup tinggi sedangkan onggok merupakan ampas dari hasil pembuatan tepung tapioka yang juga belum di manfaatan secara maksimal.Permasalahan yang sering di jumpai dalam penggunaan biobriket bottom ash batubara sebagai bahan bakar energi adalah lamanya penyalaan, bau yang tidak sedap pada saat di bakar, daya rekat briket yang tidak bagus sehingga briket mudah pecah. Tujuan dari penelitian mengetahui komposisi terbaik biobriket berdasarkan komposisi campuran, ukuran partikel dan parameter kualitas bottom ash batubara. Metode penelitian dilakukan dengan uji laboratorium.

Properly distributed sound would ensure everyone in the room to hear the same quality of sound. Good sound quality is defined as a sound that did not diminish its character (sound intensity and sound clarity) significantly to its sound source. In this research, has been fabricated an in-room sound distribution measuring instrument, based on the Arduino microcontroller that equipped with nRF24L01 to be wirelessly functionated. The fabricated measuring instrument consist of 4 transmitter devices and 2 receiver devices. The transmitter devices is an Arduino Pro Mini microcontroller that equipped with nRF24L01 and a sound sensor. The receiver devices is an Arduino Nano microcontroller equipped with nRF24L01, that connected to a PC, and an Arduino Pro Mini microcontroller equipped with nRF24L01 that connected to a speaker. The fabricated measuring instrument equipped with a Python 2.7-based acquisition software to acquire data in real time and store it in CSV (Comma Separated Value) format. Test was carried out to the transmitter devices that equipped with a sound sensor and the receiver device that connected to a speaker. The transmitter devices was compared with a standard sound level meter, and showed 0,65% - 1,24% of error percentage. The test made to receiver device showed that sound intensity of 100 dB could only be achieved with frequency of 2000 Hz and 3000 Hz. On the measurement of sound distribution, the primary data of Einstein Hall sound distribution has been obtained, with 16 sound level measuring point, 7 variations of sound source position, and 5 variations of sound source frequency.The background noise measurement of Einstein Hall of the FMIPA ULM, showed the value varied between 57 dB – 60,56 dB.","PeriodicalId":34112,"journal":{"name":"Jurnal Fisika Flux","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46775344","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}

Ecotourism on the Liang Bangkai site highlights conservation in its cultural aspects and natural authenticity, without ignoring the economic aspects that are indicated to be unique and of high value. The artifact findings on this site are far more complete than the Sakulirang site, a site recommended by UNESCO as a world heritage (Sugiyanto, B., 2010). It is not easy for local governments to determine the right strategy in tourism promotion. This is related to many factors, one of which is the carefulness and thoroughness of the local government as decision makers in determining the criteria that are the strengths, weaknesses, opportunities and threats of each tourist location. Accuracy of the local government in digging information on each criterion built both externally and internally, then analyzed so that it can provide accurate information related to tourist sites and be able to formulate appropriate and measurable decision strategies for the promotion of ecotourism. The Fuzzy Analytical Network Process - Extend Analysis Chang method is used in determining the weight of interest between criteria and sub criteria and the weight of interest between promotion strategies. Based on the perception of the importance level of the sub-criteria for promotion strategies, the level of importance was found, namely Strengts - Opportunies (21.70%), Weakness - Opportunities (34.52%), Strengt - Threats (32.54%) and Weakness - Threats (11.24%). From these results, it can be seen that decision makers still emphasize strategies to overcome internal weaknesses to capture opportunities from potential Liang Bangkai sites and utilize the potential strength of the site to overcome external threats to the site.","PeriodicalId":34112,"journal":{"name":"Jurnal Fisika Flux","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46024322","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}
