Abstract

Cervical cancer remains a major global health concern, particularly in low- and middle-income countries (LMICs), where barriers such as limited healthcare access, cultural stigma, and logistical challenges hinder routine screening. Human papillomavirus (HPV) self-sampling has emerged as a promising alternative to clinician-collected sampling, offering the potential to improve screening coverage and reduce the burden of cervical cancer. This scoping review aims to synthesize current evidence on the feasibility, effectiveness, and acceptability of HPV self-sampling, with a focus on its impact on screening uptake, psychological outcomes, and diagnostic accuracy. Following the PRISMA-ScR guidelines, a systematic search was conducted across PubMed, Google Scholar, and Scopus, resulting in the inclusion of five studies: four randomized controlled trials and one umbrella review. Findings indicate that self-sampling reduces anxiety associated with cervical screening, improves participation among underserved populations, and demonstrates high diagnostic concordance with clinician-collected samples. Behavioral interventions, such as pay-it-forward models, show potential to enhance sample return and feedback rates. However, challenges remain regarding effective triage strategies for HPV-positive cases, especially in resource-limited settings. The review supports the integration of self-sampling into national screening programs, emphasizing the need for culturally tailored approaches and continued research on cost-effective triage methods.

Abstract

Mangkalaya Village in Sukabumi Regency faces the problem of organic waste management that has not been optimally handled. Approximately 115.10 m³ of waste per month with a composition of 56% organic waste, only 36% is transported to the landfill, while the rest is burned or dumped into the environment, causing pollution, health risks, and greenhouse gas emissions. This community service activity aims to implement Microbial Electrolysis Biodigester (MEB) Technology as a solution for processing organic waste into biogas and liquid organic fertilizer, while empowering the community to become an independent village in processing waste. The approach used includes socialization, technical and business management training, construction and commissioning of a community-scale MEB reactor unit, operational assistance, and technology and socio-economic evaluation. Data were collected through field observations, interviews, reactor operational records, and documentation of the activities of ABEL Porridge and Wet Cake MSME partners. The program successfully installed one MEB reactor unit with a design capacity of 1,000 L of organic waste, to process household waste and remaining MSME raw materials. Initial operational tests showed that the reactor was able to produce biogas that began to be used on a household scale and liquid organic fertilizer that was tested on residents' land. Waste incineration practices have decreased, while organic waste sorting has increased in partner households. However, through intensive mentoring and strengthening the role of partners, most of the first-year output indicators, including technology installation, increased production capacity, the formation of management groups, and publications, have been achieved. The implementation of MEB in Mangkalaya Village has proven technically and socially feasible as the first step for an independent village to manage waste. The next phase focuses on optimizing operations, strengthening the biogas and fertilizer business model, and replication to other villages.ABSTRAKDesa Mangkalaya di Kabupaten Sukabumi menghadapi persoalan pengelolaan sampah organik yang belum tertangani optimal. Sekitar 115,10 m³ sampah per bulan dengan komposisi 56% sampah organik hanya 36% yang terangkut ke TPA, sedangkan sisanya dibakar atau dibuang ke lingkungan sehingga menimbulkan pencemaran, risiko kesehatan, dan emisi gas rumah kaca. Kegiatan pengabdian ini bertujuan menerapkan Teknologi Mikroba Elektrolisis Biodigester (MEB) sebagai solusi pengolahan sampah organik menjadi biogas dan pupuk organik cair, sekaligus memberdayakan masyarakat menuju desa mandiri mengolah sampah. Pendekatan yang digunakan meliputi sosialisasi, pelatihan teknis dan manajemen usaha, pembangunan dan komisioning satu unit reaktor MEB skala komunitas, pendampingan operasional, serta evaluasi teknologi dan sosial-ekonomi. Data dikumpulkan melalui observasi lapangan, wawancara, pencatatan operasional reaktor, dan dokumentasi aktivitas mitra UMKM Bubur dan Kue Basah ABEL. Program berhasil memasang satu unit reaktor MEB berkapasitas desain 1.000 L sampah organik, untuk mengolah sampah rumah tangga dan sisa bahan baku UMKM. Uji operasi awal menunjukkan reaktor mampu menghasilkan biogas yang mulai dimanfaatkan pada skala rumah tangga serta pupuk organik cair yang diuji pada lahan warga. Praktik pembakaran sampah berkurang, sementara pemilahan sampah organik di rumah tangga mitra mulai meningkat. Namun, melalui pendampingan intensif dan penguatan peran mitra, sebagian besar indikator luaran tahun pertama yaitu instalasi teknologi, peningkatan kapasitas produksi, terbentuknya kelompok pengelola, serta publikasi dapat dicapai. Penerapan MEB di Desa Mangkalaya terbukti layak secara teknis dan sosial sebagai langkah awal desa mandiri mengolah sampah. Tahapan berikutnya difokuskan pada optimasi operasi, penguatan model bisnis biogas dan pupuk, serta replikasi ke desa lain.

Abstract

Adolescence is a crucial phase in individual growth and development, especially for young women, who experience significant physical and hormonal changes. These changes impact reproductive health, including the regularity of the menstrual cycle. Menstrual cycle irregularities can be an early manifestation of Polycystic Ovarian Syndrome (PCOS), one of the most common endocrine disorders in women of reproductive age. Hyperandrogenism, ovulatory disorders, and polycystic ovarian morphology characterize PCOS. Its prevalence in adolescents ranges from 6–10% and tends to increase with lifestyle changes such as a high-calorie diet, lack of physical activity, and psychological stress. Pathophysiologically, PCOS involves complex interactions among genetic, epigenetic, and environmental factors that disrupt the balance of hormones LH, FSH, and AMH and cause insulin resistance. This condition triggers hyperandrogenism, inhibits follicular maturation, and leads to chronic anovulation. The diagnosis of PCOS in adolescents requires caution based on the Rotterdam Consensus (2003) and the 2018 International Guidelines, taking into account similarities to the physiological symptoms of puberty. PCOS is strongly linked to obesity, metabolic syndrome, and family history, with insulin resistance playing a significant role in its development. Elevated Anti-Müllerian Hormone (AMH) levels indicate the severity of PCOS and are associated with metabolic disorders. Therefore, a preventive, holistic approach that promotes a healthy lifestyle is essential for adolescents, including education on balanced nutrition, increased physical activity, and stress management. These measures are expected to decrease the occurrence of PCOS and long-term complications such as infertility and metabolic syndrome in young women in Indonesia.

Abstract

The gear sprocket is a transmission system component that operates under repeated torsional and frictional loads, making its surface susceptible to wear. To improve wear resistance, a treatment is required to harden the surface layer without significantly altering its dimensions. This study aims to evaluate the effect of combining ice-water quenching and varying shot peening pressures on the surface hardness and microstructural changes of a medium carbon steel gear sprocket. The specimens were austenitized at 850 °C for 15 minutes and rapidly cooled using ice water. Subsequent shot peening was performed for 20 minutes using 0.6 mm diameter steel shots at pressures of 5, 6, 7, and 8 bar. Surface hardness was measured using the Vickers (HV) method, and microstructural observations were conducted with an optical microscope after 2% Nital etching to identify phase transformations. The results show that ice-water quenching increased the surface hardness from 199 HV to 329 HV, representing an increase of approximately 65% over the untreated condition. The combination of quenching and shot peening further enhanced hardness to 404 HV, 454 HV, 487 HV, and 552 HV at 5, 6, 7, and 8 bar, respectively, with the maximum improvement reaching 177% compared to the untreated specimen. Microstructural analysis revealed fine martensitic structures on the quenched surface and a plastically deformed layer produced by shot impacts. Therefore, the combination of ice-water quenching and shot peening effectively enhances surface hardness and refines the microstructure of gear sprockets, indicating its potential application in improving the transmission components wear resistance.
