Abstract

The subject of Chemistry is still relatively unfamiliar among junior high school students because it is still part of the broader Science subject taught at that level. This is also the case at SMPN 28 Bengkulu Utara, where students are still unfamiliar with chemistry. To introduce chemistry and create a positive impression of the subject among students at SMPN 28 Bengkulu Utara, an outreach activity was conducted focusing on interesting chemical phenomena — in this case, the phenomenon of quantum fluorescence.During the activity, explanations were given about the meaning of fluorescence, the causes behind it, and its applications in everyday life. The outreach activity also included demonstrations of the fluorescence phenomenon. Participants engaged in the event enthusiastically, as seen through the students' active participation. This activity is expected to help participants become more familiar with chemistry, a subject that has long been considered difficult, intimidating, and abstract. Keywords: fluorescence; chemistry; carbon quantum dots; light

Abstract

Di era digital yang semakin terkoneksi, keberadaan situs web sebagai wajah utama sebuah institusi menjadi sangat krusial, terutama dalam sektor pelayanan kesehatan. Penelitian ini mengkaji keamanan situs web rumah sakit rsjsh.co.id dengan pendekatan penetration testing yang merujuk pada panduan OWASP Testing Guide v4. Fokus utama penelitian adalah mengidentifikasi dan memverifikasi kerentanan yang berpotensi dimanfaatkan oleh pihak tidak bertanggung jawab. Metode yang digunakan mencakup pengumpulan informasi (footprinting), pemindaian (scanning), eksploitasi kerentanan, serta evaluasi risiko menggunakan CVSS v3.1 dan OWASP Risk Rating. Hasil analisis menunjukkan adanya 11 kerentanan, di antaranya tiga berkategori sedang: tidak adanya kebijakan Content Security Policy (CSP), anti-clickjacking header, serta keberadaan mixed content. Eksploitasi dilakukan menggunakan berbagai alat seperti Owasp Zap, Burp Suite, dan seography.io. Meskipun beberapa kerentanan tidak dapat dieksploitasi akibat sistem pertahanan yang memadai, temuan valid mengindikasikan perlunya implementasi kebijakan keamanan tambahan, seperti CSP dan konfigurasi HSTS. Penelitian ini merekomendasikan perbaikan proaktif sebagai langkah penting dalam menjaga kerahasiaan data pasien dan meningkatkan kepercayaan publik terhadap sistem digital rumah sakit Kata kunci: penetration testing, keamanan web, rumah sakit, OWASP, Content Security Policy

Abstract

Lampung, including the Register 31 Pematang Arahan area which is next to the Bukit Barisan Selatan National Park, is known for its high biodiversity, and its coffee production. Gapoktanhut Lestari Sejahtera, consisting of 13 Forest Farmer Groups (KTH), practiced community-based forest coffee under the KPH Kotaagung Utara, Tanggamus, Lampung. To support the development of biodiversity data base for KPH Kotaagung Utara, molecular-based species identification for robusta coffee has been carried out under BLU LPPM Unila grant year 2023 and in collaboration with the Lampung Disease Investigation Center. Robusta coffee leaf samples from six KTH areas (Bumi Mulyo, Sido Makmur 1, Sido Makmur 2, Sido Makmur 3, Mandiri Jaya, and Murah Rejeki) were collected for molecular species confirmation based on the N-methyl transferase genetic marker. Molecular analysis included DNA extraction, amplification, and electrophoresis conducted at the Lampung Disease Investigation Center. Sequencing was based on the Coffea canephora CAF2 genetic marker. Bioinformatics analysis was performed using the Basic Local Alignment Search Tool (BLAST) and Molecular Evolutionary Genetics Analysis (MEGA) software version 6. Identical sequence lengths of samples in 6 KTH are varied in base pair length and nitrogen base sequences, ranging from 163-530 bp, with 5 out of 6 KTH having a genetic distance of 0.000%, while 1 sample had a genetic distance of 0.006%. It indicates that robusta coffee samples from 6 KTH areas are genetically closely related. It is supported by its phylogenetic tree, the coffee species cultivated by Gapoktanhut Lestari Sejahtera is molecularly confirmed to be robusta coffee, Coffea canephora.

Abstract

Pesawaran is one of the areas that has the potential to cultivate stingless bees as producers of honey and propolis. This study was aimed at qualitatively analysing partial amplicons of the 16S rRNA gene from individuals found at the research site. The research was performed from April to September 2023 in an explorative approach. Based on the exploration that has been done in Harapan Jaya Village, Way Ratai District, Pesawaran Regency, individual stingless bees were obtained from 5 different colonies. Individual samples of stingless bees were further extracted and amplified by commercial kits. Each individual from 5 different colonies has successfully obtained its DNA amplicons. Based on qualitative analysis using 1% agarose gel, the size of the partial gene ranged from 400bp to 500bp. This result is in accordance with the data contained in the genbank, where the 16S rRNA gene size is more than 500bp. Therefore, it has been concluded that the size of the partial amplicons of the 16S rRNA gene of individual stingless bees from the 5 colonies that were obtained is actually in range of the size of the 16S rRNA gene of stingless bees that have been recorded in the genbank.

Abstract

Along with the development of people's lifestyles resulted in an increasing need for vehicles. In four-wheeled motorized vehicles, the suspension system is a very important part because it can affect the safety and comfort for the rider. The spring is the main component in the vehicle suspension which acts as a medium to receive dynamic loads from the road surface and vibrations on the wheels so that they are not transmitted to the vehicle frame directly and keep the wheels in contact with the road surface. the results of testing the raw material hardness specimens and specimens after normalizing, the average hardness of raw materials is 47.6 HRa, the specimens after normalizing at a temperature of 800° get an average hardness of 29.3 HRa, on the specimens the results after normalizing at a temperature of 850° get an average hardness of 35.3 HRa, the specimens after normalizing at a temperature of 900° get an average hardness of 41 HRa.

Abstract

This article discusses local political dynamics in Indonesia, notably in the city of Metro. There are several factors why a particular candidate is more politically electable than others, including ethno-religious factors and money. Moreover, a traditional factor that needs to be considered in the study of electoral geography is the influence of the spatial effect upon voting behaviour. In the election, demographics and geography are two important factors in voting behaviour. The local election resulted in a competitive and dynamic political contest among the local elite in Metro. The result of the 2020 local election was particularly interesting because the independent candidate won and defeated the party-based candidate. This is a mixed methods approach combining the data from interviews and a qualitative survey. This research aims to analyse the spatial factor in Metro’s local election, looking at why a certain candidate won in a particular area and how the geographical factor influenced voting behaviour. Secondly, the result of the qualitative survey supported the finding that voters still consider ethno-religious factor. The finding obtained by this research reveals two significant narratives, specifically the crucial factor of ethno-religious sentiment on voting preference and the spatial factor related to residency in securing a victory for the candidate in the local election. Essentially, research concludes that the spatial factor is of importance in the context of Metro’s local election and supports Woolstencroft's (1980) classical concept of electoral geography comprising “friends and neighbours”.
