Abstract

Seedless watermelons, both seeds and fruits, possess a significantly higher economic value than their seeded counterparts. Serif Saga Agrihorti, a variety developed by the Tropical Fruit Research Institute, offers several advantages, including a sweet taste, high fruit yield, bright red flesh, and large fruit size. However, it is characterized by a relatively high number of seeds. The development of a new seedless variety from Serif Saga Agrihorti is crucial. Polyploid induction using mutagenic agents like colchicine is an effective method to obtain tetraploid female parents. This study aimed to identify the optimal method and colchicine concentration for inducing polyploidy in watermelons and to produce putative tetraploid plants. Polyploid induction was conducted using two methods: directly applying colchicine solution to plant shoots and soaking seeds in colchicine solution for 24 and 48 hours at concentrations of 0.2% and 0.4%. The observed traits included stem diameter, leaf length and width, stomatal length and width, pollen diameter, pollen viability, male and female flowering periods, harvesting time, fruit weight, fruit diameter, seed count, and seed dimensions (length and width). Data were analyzed using an unpaired t-test using the Statistical Tools for Agricultural Research (STAR) software. The results identified four putative tetraploid genotypes based on morphological observations of pollen diameter, stomatal size, and seed dimensions. In conclusion, seed soaking in colchicine solution effectively induces polyploidy in watermelons compared to shoot application.

Abstract

The rapid development of information technology presents new challenges in the field of law, especially related to cyber crime. One of the most alarming forms is the attack of extortion devices (ransomware), against Indonesia's National Data Centre (PDN). This research aims to analyse the implementation of Law No. 17/2011 on State Intelligence in overcoming the crime of blackmail devices, the impact on national security, and the relevance of Law No. 1/2024 on Electronic Information and Transactions. The method used is normative juridical with an analytical approach to legislation. The results showed that ransomware fulfils the elements of a criminal offence as stipulated in the Criminal Code and the Electronic Information and Transaction Law. In addition, the role of intelligence agencies is very important in early detection and handling of cyber threats. This research confirms the importance of synergy between intelligence agencies and legal reform in dealing with evolving cyber threats

Abstract

This research examines land use planning and land control in the buffer zone of the Asahan Hilir River, a strategic area that intersects between the City of Tanjung Balai and Asahan Regency. North Sumatra Province. The river buffer zone is a protected area that has important ecological functions but is under pressure due to the development of settlements, plantations, and infrastructure that do not align with its intended use. The method used is empirical legal research and case studies, focusing on the inventory of land ownership status and land utilization. The study results show that based on inventory data, there are still settlements established without ownership rights to the land, either in the form of land rights certificates, based on control status, found in the study area in Asahan Regency and Tanjung Balai City totaling 7344 plots, with land rights status or lease status, as well as based on the use and utilization of space, including: community settlements, government and non-government buildings, markets, public facilities, state-owned enterprise plantations, private and community plantations, as well as palm oil mills (PKS) and sand mines. There are conflicts of interest between environmental preservation, regional development interests, and community needs. This research recommends a multidisciplinary approach in reorganizing the river buffer zone, through strengthening regulations, law enforcement, community participation, and the application of incentive and disincentive systems to encourage land use that aligns with its ecological functions.

Abstract

Cocoa is one of the plantation commodities which is a source of state income. Growing media is not only related to seed germination in general, but also relates to the ability of seeds to survive even in a less favorable environment. The purpose of this study was to determine the vigor of cocoa seeds of BL50 variety on several types of germination media. The research was carried out in Nagari Tanjung Lolo, Tanjung Gadang District, Sijunjung Regency from March to April 2022. The tools used consisted of a handsprayer, ruler, caliper, and writing utensil. The materials used in this experiment were BL50 variety cocoa seeds, crushed bricks, humus soil, sand, and insecticide. The experiment was arranged according to the rules of Randomized Block Design (CRD) with 3 treatments and 4 replications, and each replication consisted of 7 samples, with a total of 84 samples of cocoa seeds. The treatments given in this study were various sprout media, namely; A = crushed brick B = humus soil, and C = sand. The data were analyzed for variance, if significantly different, it was continued with the Honestly Significant Difference Test (BNJ). The results showed that humus soil media was a good medium for accelerating germination, while sand media was good for root development which included root length and diameter.

Abstract

Penelitian ini bertujuan untuk menganalisis secara komprehensif fenomena tindakan main hakim sendiri (vigilantisme) dalam masyarakat Indonesia, dengan menyoroti faktor-faktor penyebab, dinamika sosial yang melatarbelakanginya, serta upaya penanggulangan yang relevan menurut perspektif kriminologi dan hukum pidana. Fenomena vigilantisme dipahami sebagai bentuk pengendalian sosial informal yang muncul ketika masyarakat kehilangan kepercayaan terhadap efektivitas sistem peradilan formal. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kepustakaan, yang mengkaji literatur hukum, teori-teori kriminologi, data empiris, dan peraturan perundang-undangan yang terkait. Analisis dilakukan secara deskriptif kualitatif untuk menguraikan pola, kecenderungan, serta dampak tindakan main hakim sendiri dalam konteks sosial-hukum. Hasil penelitian menunjukkan bahwa vigilantisme dipicu oleh dua kelompok faktor: (1) faktor internal, seperti kemarahan kolektif, frustasi, persepsi negatif terhadap pelaku kejahatan, serta dorongan emosional yang diperkuat oleh dinamika massa; dan (2) faktor eksternal, meliputi lemahnya penegakan hukum, rendahnya literasi hukum, ketidakpastian hukum, keterlambatan proses peradilan, serta pembiaran aparat terhadap kekerasan. Dampaknya tidak hanya menimbulkan eskalasi kekerasan dan pelanggaran hak asasi manusia, tetapi juga melemahkan legitimasi negara sebagai pemegang otoritas hukum. Selain itu, fenomena ini berpotensi menciptakan budaya impunitas dan normalisasi tindakan kekerasan yang dapat mengganggu stabilitas sosial dalam jangka panjang.

Abstract

Early childhood legal education plays a crucial role in shaping students' character to adhere to norms and laws. Basic criminological understanding is a form of legal education that needs to be implemented in elementary school students to instill the ability to recognize right and wrong behavior in social life. The purpose of this study is to examine and analyze the significant relationship between the level of basic criminological understanding and the formation of law-abiding character in elementary school students at Cintaresmi State Elementary School, as well as to measure the contribution of the level of basic criminological understanding to the formation of law-abiding character in elementary school students at Cintaresmi State Elementary School. The research method used is a quantitative method with an associative approach. Data were obtained through questionnaires that have been tested for validity and reliability, with sample determination using the Slovin formula. Data analysis was carried out using the Statistical Package for the Social Sciences (SPSS) application. The results of the study indicate a strong, positive, and significant relationship between the level of basic criminological understanding and the formation of law-abiding character in elementary school students. The correlation coefficient value shows a linear and significant relationship, while the results of the determination test show that understanding basic criminology makes a significant contribution to the formation of law-abiding character, so that the higher the level of students' understanding of basic criminology, the better the law-abiding character that is formed.

Abstract

This study seeks to dissect the operational patterns of cybercrimes that leverage deepfake technology, with a specific focus on fraud schemes that digitally superimpose the likeness of public figures onto deceptive content. Through a criminological lens, it explores the psychological and social drivers behind such acts, the multifaceted harms inflicted on victims and society, and the significant hurdles faced by Indonesian law enforcement in responding to these technologically advanced offenses. Employing a descriptive-analytical methodology, the research synthesizes case studies, legal document analysis, and theoretical frameworks to map the crime's ecosystem. The analysis uncovers a triad of enabling factors: a deficit in societal oversight that fails to curb digital misconduct, a social learning environment where deviant online behavior is acquired and normalized, and a critical regulatory vacuum that lacks laws specifically tailored to govern synthetic media. Presently, authorities are forced to apply existing statutes namely the Criminal Code (KUHP) and the Electronic Information and Transactions (ITE) Law which are often ill suited to tackle the evidentiary and jurisdictional intricacies of deepfake fraud. Consequently, this research argues for a decisive, multi-layered counter-strategy. It underscores the imperative to elevate public digital literacy, empowering citizens to critically evaluate media. It calls for the drafting of agile, forward-looking regulations that directly address content provenance and accountability. Finally, it highlights the necessity of investing in advanced detection tools capable of identifying sophisticated forgeries in real-time, thereby forming a crucial bulwark against this evolving threat to digital trust and security.

Abstract

Penelitian ini bertujuan untuk menganalisis bentuk, karakteristik, dan determinan Kekerasan Dalam Rumah Tangga (KDRT) melalui perspektif hukum dan kriminologi guna memberikan pemahaman komprehensif mengenai pola viktimisasi serta faktor penyebab yang memperkuat terjadinya kekerasan dalam lingkup domestik. Kajian ini juga bertujuan menilai efektivitas instrumen hukum positif Indonesia dalam memberikan perlindungan bagi korban serta mengevaluasi sejauh mana pendekatan kriminologi dapat memperkaya strategi penanggulangan KDRT secara preventif maupun represif. Metode penelitian yang digunakan adalah pendekatan yuridis normatif yang menelaah peraturan perundang-undangan terkait KDRT, terutama Undang-Undang Nomor 23 Tahun 2004 tentang Penghapusan Kekerasan dalam Rumah Tangga, dipadukan dengan pendekatan kriminologis untuk mengidentifikasi faktor sosial, psikologis, dan struktural yang memengaruhi perilaku kekerasan. Pengumpulan data dilakukan melalui studi kepustakaan terhadap literatur hukum, penelitian terdahulu, serta kajian kriminologi yang relevan.Hasil penelitian menunjukkan bahwa KDRT mencakup empat bentuk utama, yaitu kekerasan fisik, psikis, dan penelantaran rumah tangga, masing-masing memiliki karakteristik dan pola eskalasi yang berbeda. Dari perspektif hukum, keberadaan UU PKDRT telah memberikan dasar perlindungan yang lebih tegas bagi korban, namun implementasinya masih menghadapi kendala seperti minimnya pelaporan, ketergantungan ekonomi korban, dan stigma sosial. Sementara itu, analisis kriminologi mengungkap bahwa KDRT dipengaruhi oleh faktor internal seperti ketidakstabilan emosi, tekanan ekonomi, serta pengalaman trauma, sedangkan faktor eksternal meliputi budaya patriarki, struktur sosial yang mendukung subordinasi perempuan, terhadap kekerasan, serta lemahnya kontrol sosial. Penelitian ini juga menegaskan bahwa upaya penanggulangan KDRT harus dilakukan secara integratif melalui penegakan hukum yang konsisten, penyediaan layanan pemulihan korban, serta strategi preventif berbasis edukasi dan pemberdayaan masyarakat dan menciptakan sistem perlindungan yang lebih efektif.
