Abstract

This study aims to isolate the alcoholic patchouli from patchouli oil using a vacuum distillation method using vacuum distillation unit. The isolation process is conducted by varying vacuum pressure, distillate volume, and remaining residue volume. The vacuum pressure variated at 1, 1,5, 2, and 2,5 mmHg, distillate volume by 70, 80, and 90 ml, while remaining residue volume at 10, 20, and 30 ml. Samples were analyzed using GC-MS to determine the concentration of patchouli alcohol and analyzed using a pycnometer to determine its density. The results showed that the use of low pressure affected separating patchouli alcohol from patchouli oil. The highest patchouli alcohol content from the isolation results is 100% obtained in 10 ml of remaining residue volume at a pressure of 2 mmHg. This vacuum distillation method is quite effective.

Abstract

The LNG Receiving Hub facility is an existing facility that has not been used for a long time. In order for this facility can be used again, all equipment and piping systems must first be conditioned to a temperature close to the operational temperature of LNG, which is -160 oC. The purpose of this approach is to determine the theoretical and actual volume of LNG used for the cooling down process of the LNG Hub facility, as well as to compare it with the cooling down process for the regasification facility. An analytical approach is used in this study to determine the ideal amount of LNG needed for cooling down the facility and compare it with the actual amount of LNG that is being used for cooling down the facility. From the results of the analysis, the theoretical LNG volume needed for cooling down the LNG Hub facility is 8,176 m3 and the actual volume is 7,013.6620 m3, while the actual value for cooling down the regasification facility is 11,573.19 m3. The actual volume for the LNG Hub facility is smaller compared to regasification which can be caused by the smaller volume of pipelines and the difference in the cooling down mechanism in both facilities.

Abstract

Broadband Wireless Access (BWA) is useful for spreading and improving internet services evenly to all regions in Indonesia. While the frequency spectrum used in this Broadband Wireless Access (BWA) service is 2.3 GHz. The antenna gain test method is carried out with 3 antenna models working at the same frequency, and before the gain test is carried out, it is confirmed that the Voltage Standing Wave Ratio (VSWR) value ≤ 2 on the 2.3 GHz frequency spectrum. The test results of the parabolic Bowtie reflector antenna show that the gain value for each diameter is 6.35 dB, 7.3 dB, 7.45 dB, and 12.45 dB respectively. And the distance from the focus of the antenna to the reflector affects the Gain value for each reflector size. This antenna polarization is directional and the larger the diameter the higher the directivity value.

Abstract

Balai pengajian Babul Muta’allimin merupakan salah satu balai pendidikan agama yang terdapat di Desa Blang Awe, Kecamatan Syamtalira Bayu, Kabupaten Aceh Utara. Sekalipun sudah berkiprah lebih dari 20 tahun, balai pengajian Babul Muta’allimin sampai saat ini sama sekali tidak memiliki sarana wudhu yang memadai untuk santri. Padahal, sarana tersebut meruapakan salah satu kebutuhan utama bagi para santri yang belajar AlQurán dan sholat di balai pengajian tersebut. Kegiatan pengabdian kepada masyarakat ini bertujuan mengembangkan suatu sistem Penyedia Air Wudhu (SPAW) berbasis sumber daya lokal, yang dapat dikelola dan dirawat secara mandiri oleh mitra. Kegiatan PkM dilaksanakan dalam 3 (tiga) tahapan, meliputi: (1) Pengembangan Sistem Penyedia Air Wudhu (SPAW) untuk mitra; (2) Pembekalan pengetahuan dasar tentang operasional dan perawatan paket teknologi yang dikembangkan, serta; (3) Evaluasi keberhasilan kegiatan, menggunakan kuisioner. Setelah kegiatan PkM diselesaikan, suatu Sistem Penyedia Air Wudhu’ (SPAW) berbasis sumber daya lokal sudah tersedia untuk mitra kegiatan. Sistem tersebut mampu menyediakan air wudhu’dengan kapasitas 2,14 liter/menit pada 7 titik akses terintegrasi, dengan kualitas air yang memenuhi baku mutu air untuk keperluan hygiene sanitasi menurut Kepmenkes RI No. 32 tahun 2017. Hasil evaluasi kepuasan mitra menunjukkan bahwa mitra memberi apresiasi positif terhadap kegiatan PkM yang telah dilaksanakan.
