Microplastic (MP) is one of the most dangerous contaminants due to its ecotoxicological impact on the aquatic environment, aquatic biota, and human health. Defined as particles less than 5 mm, these contaminants originates from either primary or secondary source. Therefore, this study aimed to analyze the abundance, shape, color, size, and type of microplastic (MP) polymers. In the process, water samples were collected from 3 distinct points in the Batang Anai River, to obtain MP. Subsequently, analysis was conducted using a microscope and Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-FTIR). The results showed that the abundance of MP in the water samples ranged from 37-77 particles/L, and the most dominant shapes, colors, and sizes identified were fragments (49.44%), black (48%), and sizes >1,000 µm (33%), respectively. Characterization and interpretation of functional groups in the FTIR spectrum indicated the presence of cellulose polymer, ethylene-propylene copolymer, neoprene, and polyester. In conclusion, this report can be used as initial information to help control plastic waste pollution.

Ikhtilaful Ulama Dalam Menetukan Timbulnya Hubungan Mahram Sebab Susuan
Authors: Fauziyah Ririn
Published: January 2024

Breast milk (ASI) is a staple food and is very important for the growth of the baby. So important is the role of breast milk that when a mother is unable to breastfeed her baby sometimes chooses to breastfeed her baby to another woman. This situation is often not realized by some people that babies who have been breastfed to other women cause mahram relations between the baby and the mother who breastfeeds him. There is a cross opinion among scholars in determining milk which causes the occurrence of mahram relations both regarding milk levels, breastfeeding age, how to breastfeed and so on. Like Imam Shafi'i and some Hanbali Madhabs, for example, requiring the level of breast milk drunk by babies to reach five times the milk that can be filling can only be considered to cause mahram relations. Unlike Imam Shafi'i and some Hanbali Madhabs who have breastfeeding rates, Hanafi Imams, Malikis, and some other Hanbali Madhabs do not require five feedings because a little or a lot is the same, that is, when a baby has been breastfed by another woman, the baby and the nursing mother naturally have a mahram relationship without having to measure how many times the milk.

occurs in PPC transactions is not significant and tolerance must be given so that maqashid sharia in the economic field in the form of rawaj al-mal is realized so that economic growth becomes high, income distribution in the community and poverty reduction
Ambiguitas Norma dan Problem Teknikalitas Dispensasi Kawin pada Peradilan Agama di Indonesia
Authors: Husni Alfi , Mustofa Latif
Published: January 2024

This study aims to discuss the norms regarding the minimum marriage age and dispensation for marriage, which appear contradictory, although both are within the same law. This study employs a normative-empirical juridical approach with a judicial case study type. The normative data sources include Law Number 1 of 1974 and Law Number 16 of 2019, while the normative-empirical data consists of two judicial decisions from the Talu Religious Court. The study finds that dispensation for marriage should not be deemed a direct factor contributing to the high incidence of early marriages because this norm is not a direct instrument to curb early marriages. The relevant instruments to address early marriages are community awareness and empowerment. In certain aspects, the norm regarding marriage dispensation is also related to the status or legitimacy of children, especially when a woman applying for dispensation is already pregnant (out of wedlock). However, formally, the Compilation of Islamic Law has already clarified that legitimate children are those born within a valid marriage, without considering whether the pregnancy occurred within a valid marriage or not.

Published: January 2024

Introduction: Noise Induced Hearing Loss is a person's hearing loss either partially or completely which is permanent and can affect one or both ears caused by continuous exposure to noise in the work environment. One of the causes of Noise Induced Hearing Loss (NIHL) is working as a motorboat fisherman.

Content: NIHL can arise as a result of the interaction between genetic factors and environmental factors with the role of internal and external risk factors. The diagnosis of NIHL can be established through history taking, physical examination such as otoscopy and tuning fork tests, as well as supporting examinations in the form of pure tone audiometry.

Conclusion: NIHL will produce the impression of sensorineural deafness with a permanent nature so that the only treatment that can be given is supportive and preventive management.

Keywords: Noisy; noise-induced hearing loss; motorboat fisherman

The echocardiography shows an untreated giant intracardiac mass in a rare place in the right ventricle, obstructing the blood flow, and massive pericardial effusion. We do a pericardiocentesis first to manage the pericardial effusion. Pericardiocentesis was done in different normal locations due to ascites permagna.  Nevertheless, our patient needs emergency surgical excision as soon as possible to prevent sudden death caused by obstruction, embolic, and other complications.
Friction and Wear of the Piston Ring – Cylinder Liner System with Artificially Aged Ultra-low Viscosity Engine Oils
Authors: Nagy András Lajos
Published: January 2024

This study aims to investigate the performance of artificially aged prototype engine oils through friction and wear experiments. Experiments were performed on a piston ring – cylinder liner model system with boundary conditions derived from real-life operating conditions. The experimental design implemented two prototype oils (SAE 0W-12 and 0W-16) in unaltered and artificially aged form. An additional fully formulated off-the-shelf engine oil (SAE 0W-20) was also aged and analyzed as reference. Oil samples were artificially aged in a custom rig, to simulate long-term in-engine use through thermal cycling at 180 °C. Fourier Transformed Infrared Spectroscopy of the lubricant samples highlighted a depletion of zinc dialkyl-ditiophosphate antiwear additives in all cases, which is comparable to a selected in-service oil. Oxidation was also measurable, albeit lower compared to the in-service sample. Averaged friction coefficients showed a ranking of aged 0W-12 < aged 0W-16 < unaltered 0W-12 < unaltered 0W-16. A decrease in surface roughness was experienced with aged oil samples, whereas unaltered 0W-16 oil produced an unexpected transition in the wear phenomenon and resulted in severe wear.

Authors: Novanursandy Nikita Besty , Rachmawati Diah
Published: January 2024

Cayenne pepper (Capsicum frutescens L.) is a commodity that often experiences price fluctuations due to a decrease in the supply of cayenne pepper amidst a large market demand. One of the factors causing the decrease in the supply of cayenne pepper is the environmental conditions that experience drought stress during the dry season. Osmopriming of seeds is one method that can be used to overcome drought stress. This study aims to determine the effect of osmopriming seeds using PEG 6000 on the germination and growth of cayenne pepper plants on drought stress. This study was experimental using a completely randomized design, with 2 treatment factors and 3 replications. The first factor was the application of priming at three concentration levels: P0 (0% PEG), P1 (12.5% PEG), and P2 (25% PEG). The second factor was drought stress treatment which consisted of 3 levels, namely: K1 (100% field capacity), K2 (75% field capacity), and K3 (50% field capacity). Data analysis used univariate analysis of variance and followed by DMRT (Duncan's Multiple Range Test) advanced testing with α = 0.05. The results showed that the application of 25% PEG priming gave the most optimal results on the performance of germination and growth of cayenne pepper plants, such as plant height, root length, root fresh weight, shoot fresh weight, root dry weight, and shoot fresh weight.

Authors: BALCI Murat
Published: January 2024

Ceza muhakemesi, temel insan haklarına en ağır müdahalelerin yapıldığı bir süreçtir. Bir kişinin suçlu olup olmadığının tespiti için itham altında olanın belirli yükümlülüklere katlanması gereklidir. Bu süreçte, hukuk dışına çıkılmaması, devlet gücünün orantısız şekilde kullanılması ve henüz suçu sabit olamayan bireyin ağır mağduriyetler yaşanmaması için tarihi tecrübelerin iyi incelenmesi gerekmektedir. Orta Çağ’da engizisyon yargılamaları, ceza muhakemesinin kötüye kullanılmasının ne denli ağır sonuçlara yol açabileceğini göstermektedir. Çalışmada ceza muhakemesi hukuku tarihi bakımından acı bir tecrübe olan engizisyon mahkemeleri ve engizisyon mahkemelerindeki yargılama usulü ile uygulanan işkence yöntemlerine değinilmiştir. Bugün ceza muhakemesi hukukunda yer alan birçok ilke ve kuralın kaynağını engizisyon yargılamalarındaki acı tecrübeler oluşturmaktadır. Ceza muhakemesinin araçsallaştırılması ve bunun sonucu olarak ortaya çıkan cadı yargılamaları da unutulmaması gereken uygulamalardır. Ölmüş kişilerin yargılanması ve malvarlığı müsaderesi cezaları, engizisyon mahkemelerinin bugün hala akılda tutulması gerektiğini ortaya koymaktadır. Çalışmada engizisyon kavramı, engizisyon mahkemelerinin ortaya çıkışı, uygulanan işkence şekilleri, hükmolunan cezalar, cadı yargılamaları ve engizisyon yargılamalarının son bulması konusu üzerinde durulacaktır.
