Abstract

The take or pay contract between PT. PLN (Persero) with Independent Power Producer (IPP), a power plant belongs to PT. PLN (Persero) is no longer operated optimally, for example, the Barru steam power plant. The steam power plant is a power plant that bears the primary load. The actual conditions in the Barru steam power plant field are charged a maximum of only 3-4 hours or only when the peak load is according to the dispatcher's request. This research examines comparing the economy dispatch method to maximize conditions in the Barru steam power plant, which dispatchers no longer order maximally. So that the Barru power plant operator can determine the distribution of the power allocation ordered by the dispatcher to the two power plant units of the Barru steam power plant, the method being compared is the lambda iteration method. The basis for calculating the two ways is to calculate in advance the characteristics of the fuel consumption of the power plant when operating in one day. The primary data is data on the results of electricity production issued by the generator and fuel consumption taken from the coal feeder flow. Based on the research results, it is known that the lambda iteration method can save production costs of Rp. 9.05 per KWH.

Abstract

The independence of nurse graduates in working is an important concept to pay attention to so that nurse graduates are ready to work after completing college. Nurse graduates at the Bengkulu Ministry of Health Polytechnic are absorbed as overseas workers or as workers in the capital or other provinces. However, there are still 33% working as honorary workers in their own place. The large number of DM cases in Rejang Lebong district that experience wound complications provides an opportunity for graduates and students to carry out competent chronic wound care so that they can work as diabetes chronic wound nurses. The aim of this community service is to improve chronic wound care skills, especially for graduates and students so they can apply their skills independently in the community. The method of activity carried out was wound care training which was held on September 5 2024. There were 25 training participants consisting of graduates and students. The results of this training were an increase in knowledge and skills in caring for chronic diabetes wounds before and after being given the training with an average increase in knowledge of 4.76. From the results of observations of wound care practices, all participants were able to carry out wound care practices in accordance with standard SOPs for caring for chronic diabetes wounds. Training participants received a wound care certificate from the PPNI organization. Training monitoring was carried out by supervision of the community service team when carrying out home care and as many as 44% of participants had carried out wound care in the community. Key words: Training, Wound Care, Diabetes Mellitus

Abstract

Patients with DM in the district. Rejang Lebong reached 382 cases, and 9 people died from this disease in 2020. Diabetes Self Management Education (DSME) is a program designed to provide understanding and skills in caring for DM sufferers daily at home. This subject of this study was to analyze the effect of DSME administration on the quality of life in type 2 DM patients in the PKM Perumnas area, Rejang Lebong district. This research is a quasi-experimental study with a pretest and posttest approach with a control group design. The sampling technique used consecutive sampling involving 30 respondents, divided into 15 respondents in the treatment group and 15 in the control group. Bivariate analysis in the form of a parametric test, namely the dependent t-test and independent t-test with ? = 0.05. Researchers use computer programs for data processing and statistical analysis. The mean quality of life for DM patients was 36.20 with a standard deviation of 10.79 and p = 0.000 <0.05. This shows that after the intervention, there is an increase in the quality of life of DM patients by 36.20. There is an effect of Diabetes Self-Management Education (DSME) on the Quality of Life of Diabetes Mellitus (DM) Patients in Kab. Rejang Lebong in 2022. Education is essential for patients to change their behaviour and self-management independently to improve the quality of life of DM patients.

Abstract

Latar Belakang; Diabetes mellitus merupakan dapat menyebabkan berbagai komplikasi metabolik akut seperti ketoasiosis dan sindrom hiperglikemia yang mengakibatkan sindrome hipeglikemia hiperosmoler nonketotik (HHNK). Salah satu metode yang digunakan dalam pendidikan kesehatan dan promosi kesehatan adalah Health Belief Model (HBM). Tujuan: Menganalis efektifitas implementasi health believe model terhadap perilaku pencegahan penyakit diabetes mellitus di wilayah kerja PKM Perumnas. Desain Penelitian menggunakan metode kualitatif untuk mengetahui peresepsi subjek terhadap implementasi HBM dalam upaya pencegahan komplikasi penyakit diabetes mellitus tehadap 7 orang subjek. Penelitian ini dilaksanakan di wilayah PKM Perumnas Kec. Curup Tengah Kabupaten Rejang Lebong pada bulan Oktober sampai dengan November 2021. Pengolahan dan analisis data dilakukan dengan melakukan ongoing content analisis. Etik penelitian diperoleh dari komisi etik penelitian Poltekkes Kemenkes Bengkulu no KEPK.M/189/10/2021 tanggal 11 Oktober 2021. Hasil penelitian; didapatkan bahwa walaupun DM adalah penyakit yang berbahaya tapi tidak boleh takut dan dapat dikontrol dengan rutin berobat dan konsultasi untuk selalu menjaga kesehatan. Hambatan yang dirasakan oleh responden dalam melakukan pengobatan rutin adalah tidak adanya anggota keluarga yang mengantarkan untuk mengambil obat ke puskesmas serta adanya rasa malu karena selalu berkunjung ke puskesmas untuk mengambil obat dan panjangnya alur administrasi yang harus diselesaikan seperti mengambil surat rujukan ke Rumah Sakit. Saran: diaharapkan kepada masyarakat utuk tetap melakukan pengobatan secara rutin dan selalu melakukan deteksi dini dalam pencegahan komplikasi penyakit DM.

Abstract

Pada akhir tahun 2019, dunia digemparkan dengan munculnya penyakit COVID-19. Penyebaran penyakit COVID-19 pada saat itu berlangsung cukup cepat hingga menyebar ke berbagai negara. Hal tersebut menyebabkan banyak negara-negara yang memberikan batasan perjalanan bagi masyarakatnya dengan tujuan untuk mengurangi penyebaran dari penyakit ini. Batasan perjalanan bagi masyarakat dapat terjadi jika terjadi lonjakan kecepatan penyebaran penyakit, hal tersebut dapat dianalisis lebih awal dengan pemodelan matematika. Penelitian ini bertujuan untuk menemukan struktur kualitatif dari model penyebaran COVID-19 dan menemukan eksistensi traveling wave pada model penyebaran COVID-19. Berdasarkan penelitian yang telah dilakukan, diperoleh model PDB dan model PDP pada penyebaran penyakit COVID-19. Model PDB menunjukkan penyakit akan menyebar di dalam populasi yang menyebabkan terjadinya endemik. Model PDP menghasilkan kecepatan minimum penyebaran penyakit COVID-19 sebesar 0,3954599146 km/hari yang artinya dalam satu hari penyakit akan menyebar sejauh 0,3954599146 km. Kata Kunci: COVID-19, Pemodelan Matematika, Traveling Wave.

Abstract

The Office of the Regent of Sidenreng Rappang (Sidrap), situated on Harapan Baru Street, Batu Lappa, Watang Pulu District, Sidrap Regency, South Sulawesi, consumes 200 kWh of electricity daily for lighting, resulting in substantial energy costs. Recognizing the potential for renewable energy, especially with a daily solar radiation potential of 5.8 kWh/m2, this study proposes the implementation of a hybrid solar power plant system. The system incorporates Photovoltaic (PV) as the primary energy source, with the Grid and Generator serving as backup sources through an AC Coupling configuration utilizing Automatic Transfer Switch (ATS). The research employs a simulation approach using HOMER Pro software for system modeling, SketchUp software for solar panel layout, AutoCAD software for ATS circuit modeling, and theoretical calculations for financial analysis. The results indicate a solar power plant capacity of 39.6 kW, producing 75,701 kWh/year with an impressive 83.3% renewable penetration. From an economic standpoint, the project requires an investment of IDR 642,714,960, with a net present cost of IDR 1,573,177,823, and a cost of energy value of IDR 1,401.38/kWh. In terms of feasibility, the project demonstrates a net present value exceeding zero (IDR 216,680,041), a profitability index greater than one (1.33), an internal rate of return surpassing the credit interest rate (12.488%), and a payback period of 7 years and 7 months. These findings affirm the feasibility of the hybrid solar power plant planning project for the Sidrap Regent's Office, showcasing its economic viability and potential for sustainable energy solutions.
