Indonesia's higher education institutions are facing renewed scrutiny over sexual harassment as fresh allegations have emerged across multiple universities, prompting formal investigations and raising questions about campus safety mechanisms. The University of North Sumatra (USU) has launched an internal inquiry into a student at its Economics and Business School following claims that he sexually harassed a substantial number of fellow students, with the controversy spreading rapidly through digital platforms and generating considerable public attention.

The case at USU centres on a student identified only by his initials, CHS, whose alleged behaviour came to light when one student shared accounts of harassment with peers via social media. What began as individual complaints quickly snowballed into a coordinated response, with approximately 60 students reportedly forming a WhatsApp group to discuss their experiences and coordinate their accounts. University spokesperson Irsan Mulyadi acknowledged the seriousness of the allegations, confirming that institutional leadership was treating the matter with appropriate gravity and had initiated formal processes to investigate the accusations through established university channels.

To move forward with disciplinary or legal action, USU has activated its Sexual Harassment Handling and Prevention task force and requested that alleged victims submit official complaints through this mechanism. As of the initial reporting phase, only ten students had filed formal reports despite claims from roughly 60 individuals who had documented their experiences in the private messaging group. The disparity between the number of alleged victims and those willing to file official complaints highlights a persistent challenge in campus sexual harassment cases: victims' reluctance to engage with formal institutional processes, whether due to concerns about confidentiality, fear of social consequences, or doubts about the effectiveness of university disciplinary procedures.

The accused student was summoned to appear before the university rectorate to respond to the allegations, but had not complied with the invitation as of the time of reporting. University officials confirmed that notification of the investigation was delivered to his family residence, yet the student failed to present himself for questioning. This non-cooperation complicates the investigation process and raises questions about the university's capacity to compel participation in disciplinary proceedings, particularly when accused individuals decline to engage voluntarily.

The allegations themselves paint a troubling picture of predatory behaviour involving multiple manipulation tactics. According to accounts shared by one of the initial reporters, CHS employed diverse methods to exploit and abuse his victims, including luring individuals into private vehicles under false pretences, soliciting explicit images, arranging hotel meetings for sexual purposes, and engaging in coercive sexual interactions via video call platforms. The pattern of behaviour documented by alleged victims extends beyond physical advances to encompass psychological harassment through sexually explicit messages and the distribution of pornographic material designed to provoke distress or compliance.

Notably, the victims span beyond the USU campus, with allegations suggesting that the accused student targeted individuals from multiple institutions. The accusation also encompasses harassment directed at both female and male students, indicating that the predatory behaviour was not limited by the gender of potential targets. This broader geographic and demographic scope suggests a systematic pattern of exploitation rather than isolated incidents, lending weight to the characterisation of the conduct as serious criminal behaviour requiring intervention beyond internal university discipline.

The USU case is not an isolated phenomenon but rather part of a troubling pattern emerging across Indonesian higher education institutions. Muhammadiyah University of Yogyakarta is simultaneously investigating a faculty member from its Pharmacy Study Programme who allegedly sent sexually suggestive messages to students, with evidence appearing on social media platforms after screenshots of WhatsApp conversations were published. The lecturer in question has been suspended pending the outcome of the university's investigation, indicating institutional willingness to take immediate protective action while inquiries proceed.

The University of Indonesia confronted a comparable crisis earlier this year when screenshots revealed that law students had engaged in systematic sexual harassment of female peers and academic staff. The UI case proved significant because the institution's Sexual Harassment Handling and Prevention task force completed a thorough investigation and determined that fifteen of the sixteen accused students had committed documented harassment offences. Rather than imposing uniform penalties, UI differentiated its disciplinary response based on the severity of individual cases, suspending three students for three semesters, seven for two semesters, and four for one semester, while one student received minor administrative sanctions.

The UI precedent offers important insights for how Indonesian universities are approaching these cascading crises. Beyond punitive measures, the institution required all suspended students to undergo psychological counselling and complete anti-sexual violence educational courses, recognising that rehabilitation and behaviour modification should accompany disciplinary action. This approach acknowledges both the responsibility of institutions to protect future potential victims and the need to address the underlying attitudes and psychological factors that generate predatory behaviour among student populations.

The proliferation of these cases across Indonesian campuses reflects broader systemic vulnerabilities in higher education institutions' capacity to prevent sexual harassment and respond effectively to allegations. The role of social media in amplifying these cases is noteworthy—victims are increasingly using digital platforms to publicise their experiences and coordinate with one another, effectively circumventing or supplementing institutional complaint mechanisms that many perceive as inadequate or unresponsive. This shift represents both an opportunity and a challenge: while social media enables victims to find support and build collective voice, it also creates space for allegations to spread without institutional oversight or verification processes.

For Malaysian readers and Southeast Asian observers, these Indonesian developments carry particular relevance. Southeast Asian universities operate within similar institutional frameworks and face comparable challenges in establishing robust sexual harassment prevention systems. The frequency and seriousness of cases now surfacing across Indonesian campuses suggest that many institutions in the region may harbour similar problems that have simply not yet generated sufficient public awareness or victim coordination to become visible. The willingness of Indonesian victims to use social media collectively raises important questions about institutional accountability: if formal university complaint mechanisms are perceived as inadequate, how can institutions restore confidence and ensure that reporting is encouraged and taken seriously?

Moving forward, the cases at USU, Muhammadiyah University of Yogyakarta, and the University of Indonesia will likely influence how other institutions throughout Indonesia and Southeast Asia respond to sexual harassment allegations. The emphasis on formal investigation processes, differentiated discipline based on severity, mandatory psychological intervention, and education in anti-sexual violence principles may become models that other universities adopt. However, the persistent gap between alleged victims and those filing formal complaints suggests that institutional reform must address not only investigative capacity but also victim confidence and trust in institutional processes.
