Abstract

Limbah cair aktivitas manusia yang tidak dilakukan pengelolaan dengan baik dapat berdampak buruk terhadap lingkungan, seperti terjadinya penurunan kualitas perairan. Sand filter merupakan salah satu teknologi pengolahan air yang  memanfaatkan gaya gravitasi, sehingga biaya operasional yang dikeluarkan relatif murah. Proses pengolahan yang terjadi adalah gabungan dari proses fisik, biologis, dan biokimia, sehingga efektifitas removal polutan menjadi cukup besar. Rate filtrasi yang lambat menjadi kelemahan sand filter, sehingga perlu adanya inovasi pada media sand filter agar rate filtrasi dapat ditingkatkan namun kualitas hasil tetap optimum. Tujuan penelitian yakni mendapatkan waktu optimum filtrasi pada empat jenis media berbeda. Penelitian dilakukan dengan membuat empat unit reaktor sistem batch. Reaktor dibuat dari bahan PVC dengan ketebalan media filter 0,7 m dan ketebalan media penyangga 0,15 m. Reaktor 1 (media pasir) didapatkan waktu optimum pada menit ke-15 dengan persentase penurunan kekeruhan sebesar 80%. Reaktor 2 (media pasir dan karbon aktif) didapatkan waktu optimum pada menit ke-20 dengan prosentase penurunan kekeruhan sebesar 69%. Reaktor 3 (media pasir dan geotekstil) didapatkan waktu optimum pada menit ke-30 dengan prosentase penurunan kekeruhan sebesar 71%. Reaktor 4 (media pasir, karbon aktif, dan geotekstil) didapatkan waktu optimum pada menit ke-30 dengan prosentase penurunan kekeruhan sebesar 73%.

Abstract

Tofu wastewater is one of the residues produced by the industry, where this residue is greater than the product. Activated sludge is one of the conventional wastewater treatment techniques that can be applied to the tofu industry. Kinetic parameters are an important basis in bioreactor design. This study aims to determine the specific growth rate () and the rate of degradation of the substrate (q) in the bioreactor of tofu wastewater treatment with an activated sludge process. This study consisted of three stages, namely acclimatization 1, acclimatization 2, and the process of treating wastewater purely. Specific growth rates at each stage of acclimation 1, acclimation 2, and running were 0.0589 days-1, 0.0539 days-1, and 0.0478 days-1. Whereas the value of substrate removal rate is 0.4591 day-1, 0.4179 day-1, and 0.3761 day-1, respectively.

Abstract

Introduction: Hypertension is a manifestation of hemodynamic imbalances resulting in various cardiovascular complications and others in the body systems. The prevalence of hypertension in Indonesian adults aged 18 years was 34.1%, and it increased by 8.3%. Globally, it accounts for about 60% of deaths. This study aimed to analyze risk factors for hypertension in industrial workers. Methods: This study used a meta-analysis, a statistical method that combines previous studies to find an effect size value or summary on JASP software. Data in this study came from database online and were sorted according to the inclusion-exclusion criteria following PRISMA. In the final step, 14 research articles were collected. Results and Discussion: Noise intensity had a 1.974 times greater risk on the prevalence of hypertension in industrial workers; work period had 2.316 times greater risk; duration of exposure gave a 1.716 times greater risk; and smoking had a 1.896 times greater risk. Conclusion: The highest risks for the incidence of hypertension in industrial workers come from period of work, noise intensity, and smoking habits; while, the lowest is in the length of exposure

Abstract

Aim: The purpose of this study was to determine the efficiency and characteristics of pig wastewater treatment. This was to be achieved using ABR with the addition of effective microorganism4 (EM4) as a bio-activator during the startup process (R1) and without EM4 (R2). Methodology and Results: Piggery wastewater is poured into ABR with 12 hours HRT (hydraulic retention time), though it is reduced to 6 hours after the concentration is stable. The COD removal efficiency at 12 hours HRT was 60% (R1) and 51% (R2). However, the results did not change significantly, since the 6 hours HRT COD efficiency was 57.8% (R1) and 51.3% (R2). The biomass growth rate at R1 is faster than R2 with Food to Microorganism Ratio (F/M) 0.4-0.89 (R1) and 0.68-1.38 (R2) while the yield of methane gas formation was 0.25-0.28 L-CH4/g-COD. Conclusion, significance, and impact study: COD effluent is the total organic material present in the piggery wastewater effluent, which is discharged into water bodies without meeting the set quality standards. This damages the quality of water bodies. The wastewater treatment needs to be prioritized to meet quality standards of COD effluent. Also, the addition of EM4 to the activated sludge reactor improves the COD removal efficiency and biomass growth, though advanced treatment is still needed for piggery wastewater.

Abstract

Domestic wastewater management is one indicator of sustainable development achievement. Belian Village in Batam City, Indonesia, needs to be evaluated because it has the potential to disrupt environmental conditions. The purpose of this research is to determine the current conditions and make recommendations for domestic wastewater management solutions in Belian Village, Batam City. This study was carried out through direct observation, documentation of activities, and literature searches. From 2014 to 2020, increased access to drinking water and sanitation in Batam City was measured. Despite the increase, it is still observed in Belian Village that wastewater is discharged directly into river bodies. The river's quality will deteriorate as a result of this. To mitigate the negative effects of these activities, communal processing solutions can be implemented. By considering operation and maintenance, an up-flow filter tank can be used for wastewater treatment.

Abstract

Introduction: This study reviewed the negative impacts of artisanal small-scale gold mining (ASGM). This paper presents an examination of ASGM's impact on health, with the scope of discussion covering human diseases and disorders, toxic substances, public and miners' safety, environmental damage, socioeconomic conditions. This study contributes mitigation recommendations for ASGM in Indonesia. This research subject is important because there has not been an ASGM study that has reviewed these aspects in Indonesia. Discussion: Chronic diseases, acute diseases, infectious diseases, and disabilities can threaten local communities' health and survival. Toxic heavy metals such as mercury, cadmium, arsenic, and lead are difficult to avoid in ASGM, since they have a high level of use. Other pollutants generated by ASGM are noise and silicia dust. ASGM has caused accidents with a total of 36 minor injuries, an estimated 57 serious injuries, and 11 deaths. ASGM also causes water, soil, and air pollution; it is a threat to the geology of world heritage sites. ASGM has been proven to improve the community's economy in several parts of Indonesia. Conclusion: ASGM has proven to have a significant impact on public health, environmental sustainability, and the socioeconomic state of Indonesian society. In general, the lack of ASGM legitimization in Indonesia is an enabling factor for these impacts.

Abstract

Marine debris is an important problem because it can directly impact the environment and public health. Good waste management is required to manage coastal waste. One of the coasts on the Indonesian border, which is experiencing an increase in waste in the ocean, is Lengkang Island. This study aims to evaluate the need for waste management facilities based on waste generation and composition. This research was carried out quantitatively and qualitatively, and the generation and composition of the waste were measured by field observations. Qualitatively, this was accomplished through a literature review. The average amount of waste in the marine waters of Lengkang Island is 19.5±3.7 kg/m2. As much as 64% of the waste thrown into the sea is plastic, and the remainder consists of paper/cardboard, rubber, and wood. Managed waste is usually illegally stockpiled, collected in temporary shelters (tempat pembuangan sampah/TPS), and then burned. These problems must be resolved by planning from source, collection, and transportation to processing at the final processing site (tempat pemrosesan akhir/TPA).
