Abstract

The use of quality seeds increase productivity and competitive the success of a potato agribusiness. This study aims to determine the influence of seed size and seed origin paclobutrazol use of growth and production of potato seeds. The research conducted in Berastagi experimental farm, Karo regency, with type of the soil is andisol and altitude of 1,340 m asl. The research was beginning from February to May 2017. The design was used randomize block factorial with 2 replication. The first factor is the size of the seed (U1. small 25 g, U2. medium > 25 - 65 g and U3. large > 65 g). The second factor is the seed origin paclobutrazol use (P0. Control, P1. 7 WAP 250 ppm, P2. 7 WAP 500 ppm, P3. 8 WAP 250 ppm, P4. 8 WAP 500 ppm, P5. 9 WAP 250 ppm, P6. 9 WAP 500 ppm, P7. 10 WAP 250 ppm and P8. 10 WAP 500 ppm. The results showed that large seed size (> 65 g) was more important increasing vegetative growth of potato (plant height and canopy width, leaf area and number of tillers). The seed origin of paclobutrazole given at 8 WAP with dose 250 and 500 ppm have higher crop growth. The highest percentage of total seeds per plot is obtained by using medium size seed with use paclobutrazol 8 WAP 500 ppm (84.22%). Production of potato per plant and per plot was obtained by using medium seeds derived from the use of paclobutrazol 7 WAP 250 ppm (1.15 kg and 13.79 kg).

The study aimed to classify avocado accession based on morphological characters and to evaluate avocado accession based on predefined idiotype. The research has been conducted in January and February 2015 in three sub-districts in Solok District, representing lowland, middle and highland. The characters observed were morphological characters, both qualitative and quantitative in accordance with Descriptors for Avocado (IPGRI 1995). The calculation of genetic distance between accessions was done by Gower method. The selection of idiotypes has been done by collecting information on consumer preferences on the characteristics of avocado from fruit shops, fruit traders in traditional markets, farmers, and consumers. The results showed that 21 avocado accession of Solok regency can be grouped into two main groups, namely Idal 3 avocados and 20 other accessions. The coefficient of dissimilarity between the two groups is about 45% or with a similarity of 55%. Accessions that have many superior characters are the accession of Idal-1, Zainal and Asni-2.

Abstract

This study analyzes online fraud as one of the most common forms of cybercrime in Indonesia, which has expanded alongside rapid advances in information and communication technology. These crimes utilize digital platforms such as social media, online marketplaces, and fraudulent websites to deceive victims for unlawful financial gain. The research aims to examine online fraud from a criminological perspective by identifying its causes, patterns, and relevance to routine activity theory and differential association theory. A normative juridical method is employed, using statutory, conceptual, and case-based approaches, with qualitative and descriptive analysis. The findings show that online fraud reflects a shift from conventional fraud to digital-based crimes, driven by low public awareness of cybersecurity, easy access to technology, and weak online supervision. Several fraud schemes were identified, including online investment scams, phishing, and identity impersonation. This study highlights the need for an integrated approach that goes beyond law enforcement by emphasizing digital literacy, public education, and cross-sector collaboration to reduce cybercrime in Indonesia.

Abstract

The development of social media as part of digital technology has significantly transformed patterns of social interaction among adolescents in Indonesia. Social media no longer functions solely as a medium for communication and self-expression, but also as a social space that influences behavioral formation, including deviant and criminal behavior. This study aims to analyze the influence of social media on juvenile criminal behavior from a criminological perspective, with particular attention to social learning processes and the weakening of social control in digital environments. This research employs a qualitative method using a literature study approach by examining scientific journals, official reports, and statistical data related to social media use and adolescent behavior. The findings indicate that high intensity of social media use, exposure to negative content, and the normalization of aggressive behavior in digital spaces contribute to increased vulnerability of adolescents to criminal behaviors such as cyberbullying, online aggression, and other forms of deviance. Within the framework of Social Learning Theory, social media serves as a medium for behavioral learning through mechanisms of observation, imitation, and social reinforcement, while Social Control Theory highlights how weak supervision by families and educational institutions amplifies the risk of deviant behavior. The implications of this study emphasize the importance of preventive, non-penal approaches through strengthening social control, improving digital literacy, and enhancing the active role of families and schools to minimize the risk of juvenile criminal behavior in the digital era.

Abstract

Penelitian ini bertujuan untuk menganalisis hubungan antara pemahaman kriminologi dasar dan sikap anti-kekerasan pada peserta didik MTsN 4 Cianjur. Penelitian menggunakan pendekatan kuantitatif dengan desain korelasional dan didukung oleh data kualitatif sebagai pelengkap interpretasi. Sampel penelitian terdiri atas 64 siswa kelas IX yang dipilih menggunakan teknik total sampling. Instrumen penelitian berupa angket skala Likert dan kuesioner terbuka. Data kuantitatif dianalisis menggunakan statistik deskriptif dan uji korelasi Spearman Rank, sedangkan data kualitatif dianalisis melalui analisis tematik. Hasil penelitian menunjukkan adanya hubungan positif dan signifikan antara pemahaman kriminologi dasar dan sikap anti-kekerasan (ρ = 0,554; p < 0,001). Koefisien determinasi sebesar 30,7% menunjukkan bahwa pemahaman kriminologi dasar memberikan kontribusi yang bermakna terhadap pembentukan sikap anti-kekerasan siswa. Temuan kualitatif mengungkap bahwa sikap anti-kekerasan juga dipengaruhi oleh faktor internal, seperti empati, kontrol diri, dan literasi hukum, serta faktor eksternal meliputi lingkungan keluarga, iklim sekolah, pengaruh teman sebaya, dan paparan media. Penelitian ini menegaskan pentingnya integrasi pendidikan kriminologi dasar dalam penguatan karakter dan pencegahan kekerasan di lingkungan sekolah.
