Abstract

Objective: To evaluate the effect of testosterone replacement on epithelial and stromal changes of prostatic lobes in castrated wistar rats. Material & Method: The subjects were 30 wistars equally assigned to castrated + testosterone replacement group (n = 10), castrated group (n = 10), and control group (n = 10). After 60 days, prostatectomy was performed in all rats and prostatic specimens were analyzed by haematoxylin eosin (HE) staining under microscope. Semi–quantitative analysis was performed by evaluating growth of epithelial structure and loss of fibromuscular stroma. Results were analyzed using ANOVA test method for normally distributed data. The statistical analysis was performed using SPSS. Results: There was significant reversibility in castration + testosterone replacement groups in all prostatic lobes compared with castration groups (p = 0,010).There were 5 rats showing normal structure of prostate gland compared to control groups in all prostatic lobes (50%), and 5 showed hyperplasia in all prostatic lobes (50%). Conclusion: Testosterone deprivation can cause prostatic atrophy. Dominant atrophy was found in ventral and lateral lobes. Testosterone replacement can prevent atrophy in all prostatic lobes regardless of specific prostatic lobes.Keywords: Testosterone deprivation, testosterone replacement, prostatic lobes.

Abstract

Garbage is goods derived from human activities that are no longer used, either unused or discarded. Good waste management not only makes the environment clean and healthy, but can also improve the community's economy. Bueng Village is one of the villages in the Jantho City District, Aceh Besar Regency which is classified as underdeveloped according to the Village Development Index and classified as underdeveloped according to the Village Development Index. The livelihoods of the people in Gampong Bueng are mostly farmers, because this village is located in the mountains and filled with rice fields. The problem that occurs in Bueng Village is that there is no garbage disposal area, so a lot of garbage is thrown carelessly around the location and causes an unpleasant odor. Therefore, there is a need for a garbage disposal site that can make it easier for the surrounding community to dispose of waste in its place. So the potential for used drums is very interesting to function as a high-value trash can both from an aesthetic and economical point of view. In addition to having the advantage of a strong base material, used drums have sufficient volume. The purpose of making this trash can is to minimize waste in Bueng Village. With the trash can, there will be public awareness to collect garbage and dispose of garbage in its place so that the environment is clean and free from disease.Keywords: Used drums, environment, garbage

Abstract

Keamanan data telah menjadi bagian dari pengembangan teknologi informasi, mengingat bahwa berjuta-juta bit informasi telah dipertukarkan dalam jaringan komputer terutama di internet. Keamanan data yang menjamin bahwa data tidak terganggu selama proses transfer dari sumber ke tujuan melalui saluran-saluran komunikasi. Masalah integrity berkaitan dengan bagaimana melindungi data dari penyusup yang berusaha masuk ke sumber data, atau menyusup dalam jaringan data untuk mengubah dan merusak. Algoritma triangle chain cipher merupakan salah satu algoritma penyandian yang beroperasi berdasarkan penyandian (kriptografi) klasik khususnya dalam teknik subtitusi terhadap karakter. Setiap karakter akan disubtitusi berdasarkan kunci dan faktor pengali yang telah ditetapkan berdasarkan formula yang berlaku dalam algoritma ini. Algoritma ini melakukan penyandian pada pesan teks sebanyak dua kali dan selalu bergantung pada hasil proses sebelumnya. Hal inilah yang mendasari rumitnya pemecahan dari algoritma penyandian berantai ini.Penyandian pesan khususnya pada pesan teks merupakan salah satu hal yang sangat penting dilakukan dalam meningkatkan keamanan pesan teks tersebut dari berbagai tingkat kejahatan yang dilakukan oleh orang-orang yang tidak berhak dan tidak bertanggungjawab. Implementasi algoritma triangle chain cipher pada penyandian pesan teks dapat mempersulit siapa saja yang berhasil mengakses dan mendapatkan pesan teks untuk memahami dan mengerti, merusak, mendistribusikan, mencuri pesan teks atau tindakan lain yang dapat merugikan pihak-pihak pemilik pesan teks tersebut

Abstract

MSMEs play a vital role in the Indonesian economy, particularly in creating jobs and driving the economy. However, MSMEs in rural areas still face limited market access and technology, particularly in utilizing digital marketing. This situation is also experienced by MSMEs in Batu Mekar Village, most of whom operate in the snack food sector but lack an effective understanding of digital marketing strategies. Recognizing this issue, the University of Mataram Community Service Program (KKN-PMD) provided mentoring to MSMEs in Batu Mekar Village, focusing on local product processing, branding enhancement, and digital marketing outreach. The methods used included field observation, interviews, direct mentoring, business legalization, and digital marketing education. The results of the activities showed that the assisted MSMEs achieved improved product quality through improved packaging, simple financial management training, and the use of social media for promotion. Furthermore, several MSMEs successfully obtained business legality in the form of NIB (National Business License) and SPP-IRT (Special Business License), which strengthened their product competitiveness. Thus, this KKN program makes a real contribution to empowering MSMEs in Batu Mekar Village through improved branding, business management, and digital marketing utilization, thus making MSMEs better prepared to compete in a wider market.
