Abstract

The adolescent phase is a transition phase from childhood to adulthood. A number of studies suggest that psychotic experiences are more common in children and young adolescents compared with adults but few longitudinal studies have assessed psychotic phenomena at multiple points in time using semi-structured interviews, and none have assessed such experiences sequentially from childhood until adolescence. In one study the incidence rate of psychotic experiences increased between ages 13 and 24, peaking in late adolescence . Method Which used that is literature review. The results obtained in this literature were that there were 8 articles obtained with a year limit 2019 – 2024 and that's it done analysis about description psychotic on teenager. Conclusion: teenagers are vulnerable to mental health problems, including psychotic disorders such as schizophrenia. Maintenance Which appropriate And support family important For recovery teenager Which experience psychotic. .

Abstract

The strategic role of the agricultural sector in Samarinda City, particularly in North Samarinda District, supports food security and the regional economy. North Samarinda District holds a crucial position as an agricultural buffer zone in Samarinda, but in the past five years, there has been a significant decrease in horticultural production, such as tomatoes from 1,467.9 tons in 2021 to 263 tons in 2024, chilies from 236.2 tons to 129.9 tons, and shallots from 7.5 tons in 2022 to 1.1 tons in 2023. Various challenges, including climate change, land degradation, and urbanization, have contributed to a decline in agricultural productivity. This study aims to evaluate land suitability to optimize horticultural crop production in the region. The research method employed is a land suitability analysis using a Geographic Information System (GIS) approach, which identifies biophysical factors such as soil texture, pH, and soil depth, as well as soil sampling for further analysis. The results show that most of the land in North Samarinda District has S3 (marginally suitable) land suitability for shallots, chilies, and tomatoes. The suitability class for S3 is influenced by limiting factors such as rainfall, soil pH, erosion, and slope. Further discussion reveals that technical improvements, such as fertilization, the addition of organic matter, and terrace construction, can enhance land suitability. Through appropriate technical improvements, land suitability can be upgraded to class S2 (moderately suitable), which in practice will support increased horticultural yields and strengthen food security in North Samarinda.

Abstract

Management of water quality generated from the wastewater effluent of PT Bio Maraja Nusantara, a company that produces organic fertilizers in Makassar.. This fertilizer production activity produces liquid waste that has the potential to pollute the environment, especially local water quality. This study evaluates water quality based on Government Regulation No. 22 of 2021 concerning liquid waste management. Water quality testing measured physical, chemical, metal, and microbiological parameters. The results showed that the water quality met the quality standards set by the regulation, with the tested water not contaminated by hazardous materials such as odor, color, heavy metals, or pathogenic microorganisms. Analytical results showed the water had undetectable odor and color, low Total Dissolved Solids (TDS) content, and turbidity below the quality limit. In addition, the pH value, nitrate, nitrite, and hexavalent chrome content were also within safe limits. Microbiological testing showed the water was free from E. coli and coliform contamination. This study shows that effluent management efforts at PT Bio Maraja Nusantara effectively minimize negative impacts on local water quality and contribute to industrial water quality management literature in the sustainable agriculture sector.

Abstract

Air limbah merupakan salah satu sumber pencemar yang dapat menurunkan kualitas lingkungan apabila tidak diolah sesuai baku mutu yang berlaku. Parameter Chemical Oxygen Demand (COD) dan logam berat besi (Fe) menjadi indikator penting dalam menilai tingkat pencemaran air limbah karena keduanya mencerminkan kandungan bahan pencemar organik, anorganik, serta logam yang berpotensi mengganggu ekosistem perairan. Penelitian ini bertujuan untuk mengetahui kadar Chemical Oxygen Demand (COD) dan logam berat besi (Fe) pada air limbah workshop dan domestik di perkebunan kelapa sawit, kemudian disesuaikan hasil pengujian dengan baku mutu air limbah yang berlaku. Metode yang digunakan adalah pengujian laboratorium terhadap lima sampel air limbah. Parameter COD dianalisis menggunakan metode refluks tertutup dengan spektrofotometer UV-Vis mengacu pada SNI 6989.2:2019, sedangkan kadar Fe dianalisis menggunakan spektrofotometer serapan atom (SSA/AAS) pada panjang gelombang 248,3 nm. Hasil pengujian menunjukkan bahwa pada parameter COD, sampel kode 1 dan 2 dari limbah workshop kelapa sawit serta sampel kode 3 dari limbah domestik tidak memenuhi baku mutu, sedangkan sampel kode 4 dan 5 memenuhi baku mutu. Pada parameter Fe, sampel kode 1 dan 2 memiliki kadar Fe sebesar 28,0920 mg/L dan 12,7949 mg/L sehingga melebihi baku mutu 5 mg/L, sedangkan sampel kode 3, 4, dan 5 memenuhi baku mutu dengan kadar Fe masing-masing 0,1256 mg/L, 0,0254 mg/L, dan 0,0219 mg/L. Analisis menunjukkan bahwa beberapa sampel air limbah memiliki konsentrasi COD dan Fe yang masih melebihi ambang batas, sehingga penguatan sistem pengolahan diperlukan, terutama pada tahap pra-pengolahan, filtrasi, dan pengendalian sumber pencemar, untuk mencegah degradasi kualitas lingkungan.
