Various studies have concluded that the presence of modern minimarkets has a negative impact on traditional kiosks. One of the negative impacts is revenue s decrase of the tradisional kiosks. However, the various studies have not answered why and how the kiosts revenue decrase or even they bankrupted. Losing in competition is not a correct reason to explain the above phenomenon because the fact is €”and is perceived so by consumers €”the price of goods in traditional kiosks is cheaper than the price of the same goods in modern minimarkets.With a qualitative approach this study found that the phenomenon of revenue s decrease and even the bankruptcy of traditional kiosks were because of disruption and not because they could not compete with modern minimarkets. It is, however, differ from Chistensen's disruptive innovation theory where disruption always starts from low-end market; this research found the opposite direction, namely disruption starting from high-end market or disruption from above.

Media televisi merupakan bagian yang tidak dapat terpisahkan dari kehidupan masyarakat di Indonesia. Hampir semua rumah mempunyai televisi terutama dipulau Jawa. Hasil dari beberapa lembaga riset ternama menjelaskan bahwa penggunaan media televisi masih sangat diminati dikalangan masyarakat. Akan tetapi seiring perkembangan jaman, hadirnya media baru dengan platfom digital serupa tahun ke tahun semakin meningkat dan mendominasi. Terutama dikalangan anak muda, karakter media baru yang lebih felksibel membuat keberadaan media baru tersebut semakin digandrungi. Hasil penelitian ini menunjukan bahwa adanya perubahan pola penggunaan media konvensional ditunjukan oleh hasil rendahnya tinggkat menggunaan media televisi dengan indikasi khalayak mulai beralih menonton program televisi melalui platfom digital lain seperti youtube. Dibutuhkan sinergisitas, kreatifitas, dan kualitas program yang baik agar media televisi masih dapat terus eksis menghadapi pesatnya perkembangan teknologi di era digital

Seseorang dengan status lajang tidak terlepas dari adanya stigma negatif seperti dianggap kesepian dan gagal menjalin hubungan romantis. Penelitian ini bertujuan untuk memahami stigma yang dialami oleh lajang dan dampaknya. Selain itu juga digali mengenai kondisi nyata dari seseorang yang berstatus lajang. Metode kualitatif digunakan dengan melakukan wawancara mendalam terhadap subyek yang merupakan seorang lajang yang menerima stigma negatif. Hasil penelitian ini menunjukkan bahwa subyek sering mendapatkan pertanyaan mengenai status lajangnya, dibanding-bandingkan dengan orang lain, dan dianggap tidak laku. Kondisi tersebut membuat subyek merasa terganggu dan tidak nyaman hingga akhirnya subyek menjadi sering menghindari orang-orang yang memberikan stigma. Pada kenyataannya subyek tidak merasa kesepian karena menurutnya kebahagiaan tidak hanya diukur dari kondisi relasi romantis.

The purpose of this research is to design and realize a pipe leak detection system that can be monitored with an Android application. Water flow sensor is used to determine the flow of water, with water flow rate analysis it is possible to know the leakage area, pipe leakage rate, and the number of leaks in pipe area if there is a water flow rate decrease. The data is processed with an NodeMCU microcontroller based on Internet of Things (IoT). The accuracy of all water flow sensors after calibration is 97,53%. When testing with the determination of each leaked area the results are appropriate. The reading of each water flow rate decrease that occurs has an accuracy of determiningthe leakage rate of 90,2% while the suitability of reading the number of leakage areas depends on the detection of the leakage area and the classification of the leakage rate. The greater the water flow reads on the sensors, the precission level to determine the level of water pipe leakage is getting better, and vice versa, this is due to sensors having variable variations in flow rate readings.

<div class="WordSection1"><p align="center"><em>According to energy observers from the Institute for Essential Services Reform (IESR) the number of electricity consumers in Indonesia has increased by an average of 6-7% annually followed by an increase in the area of its services.</em><em> An increasingly broad network is directly proportional to the potential for interference with the transmission and distribution system. The 150 KV Rembang substations is part of the Java-Bali Interconnection electrical system in northern Central Java that supplies electricity to the Rembang and surrounding areas. Rembang 150 KV substation on May 24, 2019, RBG 01 feeder experienced a disturbance behind the RB1-32 recloser and it was recorded that in 2019 PMT it had been tripped 4 times. Besides, there has been a change in equipment in the form of transformer II. These problems indicate the potential for interference that is not anticipated by the protection system, namely Over Current Relay and recloser.</em><em>  This study evaluates the setting of an outgoing 20 KV OCR protections and recloser on transformer II RBG 01 feeder Rembang 150 KV substation. The scenarios used are calculations with large variations of short-circuit current based on% distance, as well as the calculation of OCR and recloser settings with IEC 60255 standards. Setting currents in the protection equipment is regulated based on current conductivity (KHA) and load current on the recloser. The coordination of the protection settings resulting from this resetting will be compared to the conditions on the ground.  </em><em>Existing (field) OCR outgoing feeder RBG 01 condition TMS OCR value = 0.228 seconds, Iset = 480 A, and t op = 0.3 seconds. The existing OCR recloser condition TMS OCR value = 0.120 seconds and Iset = 400 A. The results of OCR coordinating outgoing feeder RBG 01 obtained TMS OCR value = 0.135 seconds, Iset = 585 A, and t operation = 0.3 seconds. OCR recloser resetting conditions obtained TMS OCR value = 0.10 seconds, Iset = 240 A and t operation = 0.198 seconds. The resetting conditions have met the IEC 60255 standard because recloser working time is smaller than outgoing work time.</em></p></div>

<p>The development of increasingly sophisticated technology follows the needs of the community, one of them in the telecommunications world is FTTH (Fiber to the Home) which is an optical signal delivery format from the center of the provider to the homes of costumers by using optical fiber as a medium of delivery. Delivery by using this FTTH technology can save costs and provide better service to customers. The study was conducted by interview and observation methods with network objects and FTTH components belonging to Telkom Semarang and through the literature method by searching some literature. FTTH configuration starts with the ONT to rosette connected using a patchcord cable then from rosette to OTP using an indoor cable then from OTP to ODP outside the home is connected using a dropcore cable. ODP itself is the result of the distribution of distribution cables/ aerial cables leading to ODC. ODC to STO/FTM/ODF using feeder cable. FTTH network is very effective to use, because it can use triple play services (telephone, internet and IPTV) with just 1ONT/ modem at the customer s side.</p>

<p>The use of electricity with large capacity sometimes faces various kinds of problems. These problems include network losses and voltage drops that occur in the channel. Improvement of electric power factor at PT. Karya Toha Putra is expected to improve the quality of electric power. This improvement is also expected to reduce the cost of electricity bills at PT. Karya Toha Putra. To be able to implement improvements in the quality of the electric power, it is necessary to calculate the reactive power compensated. In this case the power factor to be achieved is 0.95. After doing these calculations, the determination of the capacitor value will be used. By doing these stages, it is expected that the installation of capacitor banks can improve the quality of electric power.

From the results of the study showed that the amount of compensation needed to improve the power factor at PT. Karya Toha Putra is 50 kVAR, divided into 5 steps with one step, a capacitor of 10 kVAR.</p>

<p class="Abstract">Hypo-hyperthermia tool is a devive that can stabilize body temperature which decreases or increases temperature dramatically. The design of hypo-hyperthermia devices has been made using Arduino Uno. Functional tests have also been carried out on the hypo-hyperthermia tool to determine the level of success and eligibility. This tool works by utilizing the flow of water to provide the temperature needed by the patient in order to obtain a normal temperature, namely by increasing the temperature of the blanket when the patient has hypothermia and lowering the temperature of the blanket when the patient has hyperthermia. The design of this hypo-hyperthermia tool uses Arduino uno as a processor and DS18B20 sensor for temperature readings. Heaters are also used as water heaters, condensers as water coolers, and water pumps to drive the water cycle from the appliance to the blanket and back to the appliance. The temperature and mode settings will be displayed on the LCD screen. Function test results obtained by comparing the value of the temperature reading in skin mode with a digital thermometer that is obtained an error value of 0.3%. This temperature difference is affected by the room temperature and body temperature of the patient which can change at any time. It was also obtained by comparison of the temperature reading values in blanket mode with a digital thermometer that is obtained the largest error value of 6% at a setting value of 25 °C and the smallest error value of 0.3% at a setting value of 30 °C. This temperature difference is influenced by the temperature of the room at the time of measurement on the blanket is also influenced by the thickness of the hose installed on the blanket, so that the cold temperature in the water is not absorbed properly.</p>
