Abstract

Permasalahan kualitas udara di kawasan perkotaan semakin serius akibat pembangunan, industrialisasi, dan padatnya jumlah penduduk. Masalah ini berdampak pada kesehatan masyarakat, seperti penyakit pernapasan dan gangguan jantung. Pengabdian masyarakat ini bertujuan memberikan informasi akurat tentang kondisi udara perkotaan dan meningkatkan kesadaran masyarakat akan pentingnya menjaga kualitas lingkungan. Sistem pemantauan kualitas udara berbasis teknologi dikembangkan menggunakan sensor multi-in-one RK300-08, yang mengukur berbagai parameter polusi udara, seperti karbon monoksida (CO), ozon (O₃), sulfur dioksida (SO₂), nitrogen dioksida (NO₂), serta partikel debu halus (PM2.5) dan lebih besar (PM10). Data pemantauan diproses dengan mikrokontroler ESP32 dan ditampilkan real-time melalui dasbor web yang dapat diakses masyarakat. Sensor ini dipilih karena kemampuannya yang komprehensif untuk mengukur parameter udara yang berbahaya bagi kesehatan. Hasil implementasi menunjukkan bahwa informasi yang diberikan cepat, akurat, dan terintegrasi, lebih efisien dibandingkan metode konvensional seperti Indeks Standar Pencemaran Udara (ISPU) yang tidak memberikan informasi waktu nyata. Evaluasi dampak sosial menunjukkan peningkatan kesadaran masyarakat yang lebih proaktif dalam mengambil langkah preventif, seperti mengurangi aktivitas luar ruangan saat udara buruk. Dengan sistem ini, masyarakat dapat berpartisipasi langsung dalam pemantauan lingkungan, mendukung terciptanya lingkungan yang lebih sehat dan berkelanjutan, serta menunjukkan potensi teknologi IoT dalam mengatasi masalah lingkungan di kawasan padat penduduk.

Abstract

Background: Malnutrition is a very common problem in hospitalized patients. Based on studies conducted in various countries, the prevalence of hospital malnutrition ranges from 20-45%. Hospital malnutrition can occur as a result of insufficient nutrient intake, impaired absorption of nutrients in the gastrointestinal (GI) tract, loss of nutrients due to disease, or increased metabolic requirement during illness. Nutrition is the basis for the healing process as it requires good nutrients through various enzymatic reactions. Some studies have shown that hospital malnutrition increases morbidity, mortality, prolongs the duration of hospitalization, and delays recovery. To improve nutritional status, a high-protein diet can be given. Liquid diet is one of the alternative forms of nutrition because it is easier to swallow.Method: This study was a double-blind randomized controlled trial conducted to assess the effectiveness of high protein liquid dietary supplementation in malnourished hospitalized patients. The patients were assessed for their nutritional status based on ESPEN 2015 criteria. Patients who experienced malnutrition will be divided into 2 groups, namely the control group which was given normal protein liquid diet, while the intervention group was given high protein liquid diet supplementation as much as 2 bottles (200 mL) per day for 7-10 days. Furthermore, the nutritional status of the patient was assessed.Results: By administering high-protein liquid diet supplementation, there was a tendency to increase the strength of the right handgrip in 3 subjects (50%), the tendency to increase body mass index (BMI) in 3 subjects (50%), Subjective Global Assessment (SGA) score improved in 2 subjects with mild/moderate malnutrition (33.3%) and 1 subject with normal nutrition (16.7%), and the tendency to increase the fat-free mass in 3 subjects (50%).Conclusion: The administration of high protein liquid dietary supplementation tended to increase the strength of the right handgrip, BMI, SGA score, and body fat-free mass index.

Abstract

Nowdays the application of wireless communication system at the airport area is very important as it is used to support the services and savety of people. In the beginning the communication is done by using Handy Talkie (HT) and the communication is limited on voice. To increase the working operation and savety of public the data communication, besides the voice, is needed. This research is designed to use wireless communication using TETRA technology on frequency 450 MHz by counting the linkbudget and are coverage of the airport. The calculation shows that the more the distance between Tx and Rx, the bigger the pathloss will be. When the distance is 5 km, the pathloss reaches 144,46dBm on the antenna receiver 1,25m. Menwhile the Rx heigh antenna does not have any significance effect on the pathloss. The coverage area for the plan can reach the distance 3,3 km when the power of transmission is 33 dBm which is enough to cover the whole area of the airport.Keywords: TETRA, Link Budget, Pathloss, Airport

Abstract

Deploying femtocells that have low power level in LTE with small coverage area is an alternative solution for mobile operators to improve indoors network coverage area as well as system capacity. However deploying femtocells (HeNB) that were used co-channel frequency, can be brought about interference problem to the Macro BTS (eNB). Close Subscriber Group (CSG) of HeNB allows only User equipment (UE) to access HeNB. HeNB is the source of interference for UE who cannot access it. Therefore it is necessary for interference coordination methods among the HeNB and eNB. The methods are ICIC (Intercell Interference Coordination) and eICIC (enhanced Intercell Interference Coordination).  This paper proposed performance analysis of scheduling schemes for Femto to macro interference coordination that allocated resource in the frequency and time domain using LTE-Femtocell suburban and urban deployment scenario. Simulation result using ICIC methods can improve SINR performance 15.77 % in urban and 28.66 % in suburban, throughput performance 10.11 % in urban and 21.05 % in suburban. eICIC methods can improve SINR performance 17.44 % in urban and 31.14 % in suburban, throughput performance 19.83% in urban and 44.39 % in suburban.The result prove using eICIC method in time domain resource have better performance than using ICIC method in frequency resource. However using eICIC method in suburban deployment scenariocan increase the performance of SINR and throughput more effective than using eICIC method in urban deployment scenario.

Abstract

The cellular subscribers’s growth over the years increases the traffic volume at Base Stations (BSs) significantly. Typically, in central business district (CBD) area, the traffic load in cellular network in the daytime is relatively heavy, and light in the daynight. But, Base Station still consumes energy normally. It can cause the energy consumption is wasted. On the other hand, energy consumption being an important issue in the world. Because, higher energy consumption contributes on increasing of emission. Thus, it requires for efficiency energy methods by switching BS dynamically. The methods are Lower-to-Higher (LH) and Higher-to-Lower (HL) scheme on centralized algorithm. In this paper propose cell zooming technique  which can adjusts the cell size dynamic based on traffic condition. The simulation result by using Lower-to-Higher (LH) scheme can save the network energy consumption up to 70.7917% when the number of mobile user is 37 users and 0% when the number of mobile user is more than or equal to 291 users. While, Higher-to-Lower (HL) scheme can save the network energy consumption up to 32.3303% when the number of mobile user is 37 users and 0% when the number of mobile user is more than or equal to 292 users. From both of these schemes, we can analyze that by using Lower-to-Higher (LH) scheme reduces energy consumption greater than using Higher-to-Lower (HL) scheme. Nevertheless, both of them can be implemented for energy-efficient method in CBD area. Eventually, the cell zooming technique by using two schemes on centralized algorithm which leads to green cellular network in Surabaya is investigated.

Abstract

Over time, cellular communication technology developed significantly from year to year. This is due to increasing the number of users and the higher needed. To overcome this problem, many providers increase the number of new base station installations to fill up the customer's needed. The increase number of base stations does not take into account the amount of power consumption produced, where in the cellular network Base Stations (BS) are the most dominant energy consuming equipment estimated at 60% - 80% of the total energy consumption in the cellular industry. In addition, energy waste often occurs in the BS where the emission power will always remain even if the number of users is small. Power consumption and energy savings are important issues at this time because they will affect CO2 emissions in the air. This paper proposes to save energy consumption from BS by turning off BS (sleep mode) if the number of users is small and distributed to other BS (neighboring BS) which is called cell zooming technique. The cell size can zoom out when the load traffic is high and zoom in when the load traffic is low. To determine the central BS and neighboring BS, a sequential to better signal (SBS) scheme is used where this scheme sorts neighboring BS based on the SINR value received (user). The results of this research, base station can be able to save energy 29.12% and reduce CO2 emission around 3580 kg/year. It means saving energy consumption which is also reducing air pollution occurs and this term can be named as green cellular network.
