Abstract

Embalut power plant is one of the power plants that supply electricity in East Kalimantan. The plant which is operated by PT. Cahaya Fajar Kaltim, has one PLTU unit with a capacity of 2x25 MW and another with the capacity of 1x60 MW. As an electricity company that must keep continuity of electric supply to customers, a reliable electrical system is necessary. Such reliable system requires protection system to detect a problem and avoid electrical equipment damage. A proper protection system should isolate the affected area and prevent black out on the other area. A type of problem may occur is a short circuit. This study analyzes the performance of overcurrent relays in 1 × 60 MW power plant unit. The analysis was performed through ETAP 12.6.0 software which was also used to design the single line diagrams, calculate the setting currents of short circuit current, also to simulate the coordination of several overcurrent relays in the system. Adjustment of the current and time value in the overcurrent relay is obtained from the result of manual calculations. The results then are displayed in the form of a characteristic curve. Afterwards, a simulation is performed in a situation where three-phase short circuit occurs at BFWP 1.3 Bus, TR AUX.3 Bus and TR 3A.3 Bus. The results show that the overcurrent relays work properly and could overcome the problem quickly.

Abstract

Background: In critically-ill patients, liver dysfunction plays a significant role on patient’s morbidity and mortality in the intensive care unit (ICU). Metabolic, hemodynamic and inflammatory factors also contribute in liver damage. Bilirubin is one of clinical markers for liver dysfunction. Some literatures indicated that patients with hyperbilirubinemia have higher mortality rate. The aim of this study was to assess the death prognosis of critically-ill patients with hyperbilirubinemia. Method: This study was an observational, prospective, and cohort study. All patients at the ICU of Kariadi hospital with hyperbilirubinemia were consecutively recruited over 8-month period from May 1st 2008 to January 31st 2009. Hyperbilirubinemia was defined as serum bilirubin levels ≥ 1.3 mg/dL for at least 72 hours and no hyperbilirubinemia was observed when the patients were admitted to the hospital. Results: Of 79 subjects who fulfilled inclusion criteria, the incidence of hyperbilirubinemia in critically-ill patients was 39.2%. About 56 subjects were enrolled in the study. Among them, 28 subjects showed hyperbilirubinemia and the other 28 subjects were included in the control group. There was no significant difference regarding the baseline characteristics of hyperbilirubinemia group and non- hyperbilirubinemia group. At the end of the study, the mortality rate in hyperbilirubinemia patients were 60.7% and 21.3% in the non-hyperbilirubinemia patients. The relative risk (RR) of death was 2.8; (95% CI = 1.3 - 6.1; p = 0.003). Conclusion: The incidence of hyperbilirubinemia was high in critically ill-patients hospitalized in the ICU of Kariadi hospital. The incidence of death between non-hyperbilirubinemia and hyperbilirubinemia subjects was significantly different. The significant relative risk of death indicates that hyperbilirubinemia may have influences on the mortality rate of critically-ill patients hospitalized in the ICU.   Keywords: liver dysfunction, hyperbilirubinemia, death

Abstract

Throughout the pandemic, all levels of society still want to continue to carry out their normal lives and activities. Including in carrying out life as individuals and in society. An example of this is community service activities that have a positive impact on the dynamics of community life. Community service is also an activity that fosters self-awareness of one’s surroundings. This self-awareness allows people to pay more attention, as a symbol of humanity. Humanity itself is an essential nature of humans that distinguishes them from other creatures. As a human being, it is something that must be done to have a greater sense of humanity towards others. The method that can be done to create a greater sense of humanity is community service. Community service can be done by anyone, including students who are studying. This activity will provide great learning in terms of socialization and living as a community side by side. Community service can be done. One of which is by socializing the positive activities that are carried out by suburban child service organizations in Surabaya. This will have an impact on the community who lacks awareness to know and participate in community service. One of them is by participating in campaigning and promoting childcare organizations to the community. One small thing that is implemented for a good purpose will shape the character and character, especially of the younger generation of Indonesia to be improved. Improving the nature and character will create leaders who have a high social spirit and that is what is needed by the Indonesian state.

Abstract

Salah satu pemberdayaan remaja masjid yang bisa dilakukan adalah dengan melakukan wirausaha di Majid, misalnya dengan wirausaha di bidang perikanan.  Wirausaha di bidang perikanan disamping untuk meningkatkan keuangan juga dapat menambah gizi bagi makanan sehari-hari. Salah satunya adalah budidaya ikan dan tanaman dengan pemanfaataan lahan pekarangan masjid serta penggunaan biaya yang murah dan tentu mudah dalam aplikasinya dapat melalui kegiatan budikdamber (budidaya ikan dan tanaman dalam ember).  Budi daya ikan di perkotaa juga perlu memperhatikan lingkungan sekitar, limbah budi daya perlu dikontrol dengan baik. Salah satu cara untuk mengontrol limbah budi daya adalah dengan penggunaan probiotik. Mekanisme kerja probiotik yang dapat mendegradasi ammonia dapat meminimalisir terjadinya pencemaran lingkungan sekitar budi daya.  Penggunaan probiotik dalam budikdamber juga perlu dilakukan untuk guna menciptakan budidaya yang ramah lingkungan Metode yang digunakan pada kegiatan PkM ini antara lain metode pra kondisi, ceramah dan diskusi, anjangsana dan anjangkarya, serta evaluasi.  Kegiatan ini bertujuan untuk meningkatkan kapasitas Remaja Masjid Al Iman dalam pelaksanaan urban aquaculture melalui teknologi probiotik dalam budikdamber yang memperhatikan kelestarian Lingkungan untuk mewujudkan ecopreuner mosque. PkM telah dilakukan selama 4 bulan, dengan luaran yang dihasilkan yaitu peningkatan pengetahuan dan keterampilan risma tentang budikdamber yang dapat diihat dari hasil pretest dan posttes.

Abstract

Alginat Sargassum telah terbukti mampu meningkatkan imunitas udang vannamei. Kegiatan Pengabdian kepada Masyarakat (PkM) ini  bertujuan melakukan diseminasi hasil riset suplementasi alginat untuk meningkatkan produksi udang vannamei di tambak masyarakat di Desa Berundung, Ketapang, Lampung Selatan. Metode PkM dilakukan dengan survei lokasi, pemetaan masalah, ceramah, diskusi, pelatihan, dan diseminasi alginat di tambak udang vannamei. Peserta PkM adalah para teknisi tambak, anak kolam, dan pemilik tambak di sekitar kecamatan Ketapang, Lampung Selatan dan sebagian berasal dari Kecamatan Pasir Sakti dan Kecamatan Labuhan Maringgai, Lampung Timur. Hasil kegiatan PkM menunjukkan adanya peningkatan pemahaman dan ketrampilan peserta terkait pembuatan alginat dari Sargassum, pemanfaatan alginat pada budidaya udnag vananmei dan manajemen kesehatan dalam budidaya udang di tambak. Hasil diseminasi menunjukkan adanya peningkatan laju sintasan udang vannamei dan dapat dilakukan panen parsial sebanyak dua kali pada hari budidaya (day of culture, DOC) 60 dan 67. Hasil sangat dirasakan manfaatnya oleh mitra setelah dua siklus budidaya sebelumnya selalu mengalami kegaglan panen. Kegiatan ini telah memberikan dampak positif bagi masyarakat khususnya mitra, baik secara ekonomi maupun sosial sehingga diharapkan tetap berlanjut dan memberikan dapak positif bagi pembudidaya udang vannamei lainnya
