Development of conceptual framework for cyber fraud investigation

The increase in the number of internet users in Indonesia as much as 175.4 million as recorded in the Datareportal.com report and 4.83 billion globally, impact the increase in the number of cyber fraud cases. Data states that 96% of fraud cases are not resolved due to fraud methods carried out online and make it difficult for legal officers to obtain evidence. Previous fraud investigation research mainly focused on fraud detection, so this research focuses on submitting a framework for investigating cyber fraud cases. The cyber fraud case requires a new framework for investigation because in this fraud case, there is digital evidence that is very prone to be damaged, lost, or modified, which makes this case unsolved. This research aims to develop a framework that is expected to help auditors to uncover cases of cyber fraud so that resolved cyber fraud cases can increase. The method used in making this framework uses Jabareen's conceptual framework development method, which consists of 6 stages, namely, Mapping the selected data source, extensive reading and categorizing of the chosen data, Identifying and naming objects, Deconstructing and categorizing the concept, Integrating concept, Synthesis, resynthesis. And make it all sense. The framework for cyber fraud investigation uses 22 digital forensic frameworks and eight frameworks for fraud audit investigations. The results of developing a framework using the Jabareen method resulted in 8 stages, integrating various concepts selected from digital forensics and fraud audits. Evaluation of framework development was carried out by giving limited questionnaires to practitioners and academics, which produced 89% for the feasibility value and needs of the framework and 67% there is no need for changes to the framework being developed

Penyuluhan Pengetahuan tentang Narkoba pada Penggiat Anti-narkoba di Kota Tasikmalaya

Masih maraknya penyalahgunaan narkoba di masyarakat yang akan berpengaruh terhadap perkembangan dan kemajuan bangsa Indonesia di masa depan maka perlu adanya pengetahuan dan pemahaman tentang narkoba. Karena ini, diperlukan kegiatan-kegiatan yang mendukung pada peningkatan dan pencegahan penyalahgunaan narkoba.

Hasil pengabdian masyarakat dapat berjalan dengan lancar dan adanya pemahaman peserta pengabdian masyarakat tentang narkoba

HUBUNGAN POLA HIDUP DAN BERAT BADAN MAHASISWA PENDIDIKAN BIOLOGI SEMESTER 7A

ABSTRAK Kualitas pola hidup mempengaruhi indikasi dari berat badan. Mahasiswa sebagai akademisi dituntut untuk memiliki kualitas hidup yang sehat..Tujuan dari penelitian ini untuk mengetahui pengaruh pola hidup terhadap berat badan mahasiswa pendidikan biologi kelas 7A. Metode yang digunakan  bersifat survey analitik dengan study cross sectional. Pengambilan sampel dilakukan dengan menggunakan teknik sampling kuota yaitu semua mahasiswa Pendidikan Biologi semester 7 kelas A UIN Sunan Gunung Djati Bandung sebanyak 37 orang. Hasil dari penelitian ini mahasiswa rata-rata memiliki pola hidup yang sama, kecuali pada faktor genetik. Maka simpulan yang didapatkan faktor yang paling berpengaruh pada kondisi berat badan adalah faktor genetic dengan persentase ibu yang ideal 50% dan ayah yang ideal 57,7 %. Kata kunci : Berat Badan, Pola Hidup, Mahasiswa ABSTRACK Quality of life patterns influences the indication of body weight. Students as academics are required to have a healthy quality of life. The purpose of this study is to determine the effect of lifestyle on the weight of 7A grade biology education students. The method used is analytical survey with cross sectional study. Sampling was carried out using quota sampling techniques, namely all Biology Education students in the 7th grade of AIN Sunan Gunung Djati Bandung as many as 37 people. The results of this study on average students have the same lifestyle, except for genetic factors. So the conclusion that the most influential factor influencing weight condition is genetic factor with the percentage of ideal mothers 50% and ideal father 57.7%. Keywords: Weight, Lifestyle, Students 

Pengaruh Perbedaan Rasio Mol Gliserol dengan Asam Asetat dan Jumlah Katalis terhadap Konversi Reaksi Asetilasi Gliserol Menggunakan Katalis Karbon Teraktifasi-Asam Sulfat

Esterification of glycerol with acetic acid produces highly important oxygenated biofuel additives, which are generally called as acetins namely, mono acetyl glycerol, di acetyl glycerol, and tri acetyl glycerol. Individually, each acetylated product has its own potential applications in various fields. Generally, esterification of glycerol is performed over homogeneous mineral acids. However, the use of these mineral acids is usually limited by several technical and environmental drawbacks. The challenge is to replace them with highly efficient heterogeneous solid acid catalysts which are easier to separate from the products, stable at high temperatures and less toxic. This study is to perform activated carbon catalyst on esterification of glycerol by varying molar ratio glycerol to acetic acid (1:3, 1:4, 1:5, and 1:6) and amount of catalyst (3%, 5%, 7% and 9%). The highest conversion was about 81.19% which was performed at 1:6 molar ratio and 5% catalyst amount

Glycerol Acetylation: Effect of Graphene Oxide Catalyst Mass Percentage on Glycerol Conversion and Acetin Selectivity

Glycerol, a byproduct of the transesterification reaction has a wide range of applications. Acetylation is a promising method for converting surplus glycerol into mono-, di-, and tri-acetin, which is used in the cosmetic, pharmaceutical, polymer, and fuel additive sectors. The kind of catalyst and reaction conditions influence glycerol conversion and acetylation selectivity. Acetylation of glycerol was performed in this study by reacting acetic acid and glycerol with a graphene oxide catalyst produced using the Hummers method. The amount of graphene oxide catalyst (3%, 5%, and 7%) in the reaction mixture was adjusted to see how it affected glycerol conversion and reaction product selectivity. Other variables such as the glycerol:acetic acid mole ratio of 1:9, reaction temperature of 120oC, stirring speed of 1000 rpm, and reaction time of 120 minutes were held constant. Glycerol conversion improves with increasing catalyst mass in the reaction mixture, with the highest conversion (92.1%) achieved when employing a 7% catalyst mass, with its selectivity to monoacetin, diacetin, and triacetin being 70.2%, 4.2%, and 25.6%, respectively

The Research Program Merdeka Belajar Kampus Merdeka and the Community Dedication based on Research Result is implemented in society. In previous study, Tempuyung and Breadfruit leaves contain flavonoid which can shed kidney stones. The dried Breadfruit leaves contains higher potassium rather than the fresh ones and it’s about 573,68 mg/kg. Ca oxalate was 81.73 % soluble in boiling water of leaf’s breadfruit tea when it consumed once a day for seven days. The method for increasing the production of kidney stone laxative herbal medicines have three steps: preparing the team and partner there are GAPOKTAN Mekar Makmur and Group of society RW VI Krapyak, Semarang. The results of this study need to implemented in society. The step of implementation held in RW VI hall, practice making product of tea bag and brew, also making reports. Based on the questionnaire data, the benefits of this program increase public knowledge about Tempuyung and Breadfruit leaves for shedding kidney stones. The average of increasing knowledge about Breadfruit and Tempuyung leaf goods is 28%, 44% packaging and labelling, and 45% in product marketing. The output is documentation videos, publication in social media, journal community service also the product tea bag and brew of Tempuyung and Breadfruit leaves as well as the other herbal drinks (turmeric, ginger and temulawak)
