Abstract

Pencemaran udara merupakan salah satu zat yang dapat membahayakan kehidupan serta kesehatan manusia. Pencemaran udara dapat timbul dari sumber alami alam maupun kegiatan manusia salah satu nya limbah pabrik seperti asap yang di hasilkan dari pabrik kelapa sawit .Pencemaran udara yang terjadi dipicu dari bentuk gas, cair, dan padat tertentu yang terpendam di udara. Partikel berasal dari aerosol, debu, asap pabrik, kebakaran hutan, asap kendaraan bermotor, dan asap rokok. Beberapa polutan yang biasanya menyebar, yakni logam berat, karbon monoksida (CO), nitrogen oksida (NOx), ozon (O3), senyawa organik volatil (VOC), dan sulfur dioksida (SO2). Indonesia sendiri masuk dalam jajaran negara yang tingkat polusinya cukup tinggi. Limbah kelapa sawit adalah sisa hasil tanaman kelapa sawit yang tidak termasuk dalam produk utama atau merupakan hasil ikutan dari pengolahan kelapa sawit. Berdasarkan tempat pembentukan limbah kelapa sawit dapat digolongkan menjadi dua jenis yaitu limbah perkebunan kelapa sawit dan limbah insdutri kelapa sawit (Eko, 2013). Pencernaan pabrik kelapa sawit berasal dari unit interaksi pengukusan (sanitasi), siklus penjelasan dan pelepasan dari hidrosiklon. Dari hasil kajian tersebut, kemudian dapat dikaji dan disimpulkan bagaimana performa perusahaan dalam melaksanakan pengelolaan dan pemantauan lingkungan hidup di sekitar areal usaha. (Badrun, 2010) Jenis penelitian yang digunakan adalah penelitian kualitatif yang bersifat naratif melalui pengambilan data,survei,observasi lapangan serta kajian dokumentasi yang dicermati dari Dampak Limbah Pabrik Kelapa Sawit terhadap Kelestarian Lingkungan Hidup Dilingkungan masyarakat PT LSP Bahorok.Pencemaran udara merupakan salah satu zat yang dapat membahayakan kehidupan serta kesehatan manusia.

Air pollution is a substance that can endanger human life and health. Air pollution can arise from natural sources and human activities, one of which is factory waste such as smoke produced from palm oil factories. Air pollution that occurs is triggered by certain gas, liquid and solid forms that are pent up in the air. Particles come from aerosols, dust, factory smoke, forest fires, motor vehicle exhaust and cigarette smoke. Some of the pollutants that are usually spread are heavy metals, carbon monoxide (CO), nitrogen oxides (NOx), ozone (O3), volatile organic compounds (VOC), and sulfur dioxide (SO2). Indonesia itself is included in the ranks of countries with high levels of pollution. Oil palm waste is the residue from the oil palm plant which is not included in the main product or is a by-product of oil palm processing. The digestion of the palm oil mill originates from the steam interaction unit (sanitization), the digestion cycle and the release of the hydrocyclone. From the results of this study, it can then be studied and concluded how the company's performance in carrying out environmental management and monitoring around the business area. (Badrun, 2010) The type of research used is qualitative research that is narrative in nature through data collection, surveys, field observations and documentation studies that examine the Impact of Palm Oil Mill Waste on Environmental Preservation in the PT LSP Bahorok community. Air pollution is a substance which can endanger human life and health. Air pollution can arise from natural sources and human activities, one of which is factory waste such as smoke produced from palm oil factories.

Abstract

The purpose of this study is to evaluate the implementation of the murabahah contract at the Ummahat Al-Kaffah Binjai Sharia Cooperative and assess its compliance with the DSN-MUI Fatwa No.04/DSN-MUI/IV/2000 concerning murabahah. The study employs a qualitative method, which involves gathering descriptive data in the form of spoken or written words from people or observable behavior. Specifically, the research is empirical, aiming to observe and analyze how the law is applied in society. Data collection was conducted through interviews with informants to obtain direct information. The findings reveal that the cooperative allows its members to purchase goods for murabahah financing, including motorcycles, laptops, mobile phones, and business capital. Overall, the implementation of the murabahah contract at the Ummahat Al-Kaffah Binjai Sharia Cooperative largely adheres to the DSN-MUI Fatwa, although there are discrepancies in the fatwa's provisions. Notably, the fatwa's point 4, which stipulates that the cooperative should purchase goods in its own name, is not followed as members buy the goods in their own name, which deviates from the fatwa's guidelines

Abstract

This research is motivated by the low mathematical communication ability of students in expressing ideas and relating the knowledge students have to real situations. This study aims to determine the contextual learning model influences students' mathematical communication ability better than the direct learning model. This research is a quasi-experimental research. The population of this study were all fourth grade students at SDN 050660 Kwala Bingai, Stabat, which consisted of three parallel classes with a total of 89 students. The sampling system used was cluster random sampling with classes IVA and IVB classes being sampled. Class IVA as the control class consisted of 30 students and class IVB as the experimental class consisted of 27 students. Data analysis was performed by two-way analysis of variance (ANOVA). The results showed that the contextual learning model had a better effect on students' mathematical communication abilities compared to the learning model. This shows that the contextual learning model provides a good change in developing students' mathematical communication ability.
