Abstract

Analysis of power flow in the power system is used to determine the parameters of the system itself. The benefit of the power flow analysis is to determine whether the amount of power in the electric power system still meets the predetermined limits, as well as to determine the number of existing losses, and to obtain the initial conditions for planning the new system. To solve the power flow problem, a power flow simulation can be performed using ETAP software. Simulations were carried out using the Newton-Rhapson method to determine the flow of power during the rainy and dry seasons. The results of the power flow simulation in the rainy season show that the highest active and reactive power values ​​are found in bus 1, namely 156.78 kW and 101.77 kVAR, while the simulation during the rainy season shows the highest active power and reactive power in bus 1, which is 137.85 kW and 88.97 kVAR. Then the highest voltage drop in the rainy season is 3.11% and the dry season is 2.78%. The Newton-Rhapson method requires 2 iterations to reach a convergent value.

Abstract

Kemumu berada di Kecamatan Armajaya Kabupaten Bengkulu Utara dengan luas kecamatan mencapai 68 km2. Kelurahan Kemumu memiliki potensi lahan budidaya pertanian khusunya padi sawah yang terluas di Kabupaten Bengkulu Utara yaitu 960,52 ha dan luasnya mencapai 1,13% dari total luas sawah di Provinsi Bengkulu. Hasil survei dan wawancara terkait potensi dan permasalahan serta kebutuhan masyarakat di Kelurahan Kemumu Kabupaten Bengkulu Utara yang didapati terkait dengan potensi sumber daya lahan sawah dan produksi padi yang tinggi di kawasan ini adalah pengelolaan limbah sisa panen padi yang belum mampu dimanfaatkan secara baik oleh masyarakat tani. Tujuan pengabdian ini adalah untuk memberikan pengetahuan dan pelatihan kepada anggota kelompok wanita tani Kemuning Kelurahan Kemumu Kabupaten Bengkulu Utara dalam pengelolaan limbah sisa panen padi berupa jerami menjadi pupuk organik cair yang kaya akan unsur hara dan dapat dimanfaatkan oleh tanaman sebagai sumber energi di tanah sawah di daerah tersebut serta menjadi solusi alternatif untuk meningkatkan kualitas lingkungan yang terhindar dari pulusi sampah menumpuk yang lama terombak di permukaan tanah. Metoda yang digunakan adalah PRA (Partical Rural Appraisal) yang memungkinkan masyarakat di Kelurahan Kemumu melalui Kelompok Wanita Tani Kemuning dapat saling berbagi, meningkatkan dan menganalisis pengetahuan tentang pembuatan pupuk organik cair dari jerami padi dan aplikasi pemanfaatannya di lahan pertanian. Hasil pengabdian menunjukan tingginya minat dan penambahan pengetahuan masyarakat sebesar 68% dalam pembuatan POC dari limbah padi ini. Hal lain manfaat dari pupuk organik cair juga mampu meningkatkan nilai ekonomi limbah sisa panen padi serta menekan penggunaan pupuk sintetis yang mahal dan sulit diperoleh oleh masyarakat tani.

Abstract

The Government of the Republic of Indonesia has long encouraged the use of renewable energy, but in fact there are still many people who use primary energy. Seeing this, the idea emerged from the Community Service Team by Bengkulu University lecturers to design and implement Solar Power Plants (PLTS). This renewable energy idea was implemented at the Qoryah Thoyyibah mosque, Kandang Limun Kota Bengkulu. The purpose of this service is the implementation of Appropriate Technology, namely PLTS for alternative energy supply at the Qoryah Thoyibah Mosque facility. So that if there is a power outage by PLN, the facilities at the Qoryah Thoyyibah Mosque can still operate according to their functions. This service method is carried out by two methods, namely counseling and implementation of PLTS Appropriate Technology. It is hoped that in the future by designing and building PLTS as an alternative energy source at the Qoryah Thoyyibah Kandang Limun mosque in Bengkulu City, the backup electricity supply will be fulfilled and we will not always depend on PLN, besides that it can also reduce the monthly cost of electricity at the Qoryah Thoyyibah Mosque. The result of Community Service activities with the 2023 Development scheme is that PLTS has been installed with an AC source to operate lighting lamps with a capacity of 100 WP for PLTS and lamps of 800 Watts. So that it can be operated as a source of lighting for Qoryah Thoyyibah mosque facilities in a state where there is no source from PLN.

Abstract

Hyperemesis Gravidarum (HG) is a pregnancy complication that is often overlooked as it is typically considered normal. If HG is not properly treated, nutrition will not be fulfilled which can negatively affect maternal and fetal health and even maternal and fetal death. The exact cause of HG is not identified, so there are no effective preventive methods. However early detection can help for prompt and appropriate treatment. Therefore, a monitoring system for pregnancy conditions was designed for HG early detection. This system employs the MPX5050 DP pressure sensor for measuring blood pressure, the MAX30100 for assessing maternal heart rate and oxygen saturation, the MAX4466 sensor for monitoring fetal heart rate, and an expert system using the certainty factor method to diagnose the probability of hyperemesis gravidarum. The expert system achieves an accuracy of 93.33%. In comparison to the aneroid sphygmomanometer, the designed sphygmomanometer reveals a mean difference of 3.5 mmHg for diastolic pressure, with a standard deviation below 8 mmHg for both systolic and diastolic pressures. The measurement of heart rate and oxygen saturation has a deviation of 1.8 % and 1.02 % respectively. These deviations align with the standards specified by the Ministry of Health for medical devices. For the fetal heart rate, the mean deviation is 3.4 bpm, and the measurement error is 2.38%. Thus, this system can be utilized to monitor pregnancy conditions, enabling the early detection of hyperemesis gravidarum

Abstract

Proses pengemasan semen PCC di PT. Cemindo Gemilang Plant Bengkulu menggunakan alat bernama Rotary Packer 8 SRC. Alat ini memiliki kemampuan untuk mengemas 8 kantong semen secara simultan. Sensor encoder digunakan dalam rotary packer untuk memantau proses pemutaran, serta sudut posisi atau putaran selama pengemasan semen. Jenis sensor encoder yang digunakan adalah jenis inkremental, yang merupakan jenis rotary encoder yang dapat mengukur perubahan sudut. Rotary Packer 8 SRC juga dilengkapi dengan load cell untuk mengukur berat timbangan dari setiap kantong yang diisi. Load cell yang digunakan adalah jenis Bending Beam dengan tipe Z6FC3 yang diproduksi oleh HBM, dengan kapasitas pengukuran hingga 500 Kg. Penelitian ini bertujuan untuk menganalisis sistem kerja sensor encoder dan load cell pada sistem pengemasan semen. Kinerja kedua sensor dianalisis dengan membandingkan hasil pengukuran dengan batas toleransi 5% yang telah ditetapkan. Berdasarkan hasil pengukuran, nilai posisi sudut discharge bag tertinggi tercatat pada posisi 317º dengan nilai error sebesar 1,6% pada sensor encoder. Nilai timbangan tertinggi adalah 50,50 kg atau terdapat error 1% pada sensor load cell. Nilai error pada kedua sensor tersebut tidak melebihi batas toleransi yang telah ditetapkan sehingga disimpulkan kedua sensor masih berfungsi dengan baik.

Abstract

Capacitive Voltage Transformer (CVT) adalah salah satu komponen penting pada sistem gardu induk. Fungsi CVT adalah untuk mengubah besaran tegangan dari tegangan tinggi ke tegangan rendah atau memperkecil besaran tegangan pada sistem tenaga listrik untuk pengukuran dan proteksi. Pemeliharaan dan perawatan yang terjadwal membuat CVT bekerja sesuai fungsi nya dalam beroperasi. Pengujian tahanan isolasi adalah salah satu pemeliharaan yang dilakukan. Pengujian ini dilakukan pada bay penghantar Tes 1/70 kV PT PLN (Persero) Gardu Induk Pekalongan, yang merupakan pemeliharaan pencegahan (preventive maintenance). Pemeliharaan gardu induk dilakukan dalam kondisi padam setiap dua tahun dan terdiri dari tiga proses utama: pengukuran, pengujian, dan perbandingan hasil uji dengan standar. Hasil pengujian menunjukkan bahwa data tahanan isolasi memenuhi standar yang berlaku, menandakan bahwa CVT masih berfungsi dengan baik dan layak digunakan dalam sistem tenaga listrik.
