Abstract

The study of butterfly in the in Air Dingin Landfills needs to be carried out to find out what types of butterflies are in this area and how their diversity is, given the increasing area of Landfills that will change the surrounding environment into a place of rubbish heap. The study was conducted by implementing survey method with insect net. The collection of butterflies was carried out in 2 periods (2x6 = 12 days) in April-June 2019 during sunny weather from 09:00 – 12:00 of Western Indonesian Time. All butterflies were collected at ±5 m distance from the collector. The data was analysed to calculate abundance, relative abundance, frequency of the presence of butterfly, and determine diversity was conducted by using the Shannon-Wiener Index and Evenness index. The results obtained 5 families, 14 genera, 22 species, and 220 individuals consisting of 122 males and 98 females. The diversity index value obtained was 2.27 and categorised as the medium category it is mostly because, as assumed, the environmental conditions of the Air Dingin Landfills were still in good condition.

Abstract

Abstrak Penelitian kupu-kupu di Sumatra Barat masih belum banyak dilakukan. Khususnya pada kawasan Tempat Pembuangan Akhir (TPA) Air Dingin yang berfungsi sebagai tempat timbulan sampah 400-450 ton/hari. Sehingga penelitian ini perlu dilakukan untuk mengetahui jenis kupu-kupu apa saja yang ada di kawasan ini mengingat semakin luasnya area TPA yang akan merubah lingkungan disekitarnya menjadi tempat timbulan sampah. Penelitian dilakukan menggunakan metode survey dengan jala serangga (insect net). Pengoleksian kupu-kupu dilakukan 2 periode (2x6=12 hari) pada bulan April-Juni 2019 pada saat cuaca cerah dari pukul 09.00 – 12.00 WIB. Semua kupu-kupu dikoleksi dengan jarak ± 5 m dari kolektor. Hasil penelitian didapatkan 5 famili, 14 genera, 22 spesies dan 218 individu. Kata Kunci: Kupu-Kupu (Rhopalocera), Lepidoptera, TPA Air Dingin Abstract Butterflies research in West Sumatra is still not much done. Especially in the Final Disposal Site (FDS) in Air Dingin area which functions as a place for waste generation of 400-450 tonnes/day. So this research needs to be done to find out what types of butterflies exist in this area considering that the increasingly large landfill area will change the surrounding environment into a place for waste generation. The research was conducted using a survey method with insect nets. Butterfly collection was carried out in 2 periods (2x6=12 days) in April-June 2019 when the weather was sunny from 09.00 – 12.00 of Western Indonesian Time. All butterflies were collected within ± 5 m from the collector. The results obtained 5 families, 14 genera, 22 species and 218 individuals.

Abstract

Hazardous and Toxic Waste (B3) is a result waste from various activities that contain harmful and toxic materials. According to the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia No. P.56 of 2015, hospitals are categorized as healthcare facilities required to manage B3 waste. The significance of managing B3 waste in hospitals is substantial, as improper management can lead to various negative impacts. During the management process, particularly during the sorting of B3 waste at the source, there are frequent issues with incorrect packaging and contamination. Such packaging errors during sorting can lead to workplace accidents.The objective of this research is to assess the B3 waste management system at RSUD Pasaman Barat, focusing on whether the processes of sorting, packaging, storage, and transportation comply with Permen LHK No. 56 of 2015, which outlines the procedures and technical requirements for managing hazardous and toxic waste from healthcare facilities. This research employs a qualitative method to evaluate the management system of hazardous and toxic waste (B3). The findings indicate that RSUD Pasaman Barat generates an average of 1,740.51 kg of B3 waste per month. Overall, the processes involved in managing B3 waste at RSUD Pasaman Barat-from sorting and packaging to transportation and temporary storage-still exhibit several non-compliances with Permen LHK No. 56 of 2015.

Abstract

The Air Dingin Landfill (TPA) in Padang City is a major waste disposal site, with open burning and waste decomposition activities producing hazardous gas emissions. This study aims to analyze the concentrations of sulfur dioxide (SO₂) and carbon monoxide (CO) as air pollution parameters around the landfill. Sampling was conducted in the active area of the Air Dingin Landfill on May 19, 2025. Laboratory analysis compared the concentrations of SO₂ and CO to ambient air quality standards established by Government Regulation No. 22 of 2021. The results showed that the SO₂ concentration was 173 µg/m³ and CO was 4,170 µg/m³, both exceeding the established standards. These findings indicate the need for emission management and combustion activity control to minimize the impact of air pollution.

Abstract

Palm oil mill liquid waste contains high organic matter and nutrients, such as Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solid (TSS), and low acidity (pH). If this liquid waste is discharged directly into water bodies without treatment, it will pollute the environment and disrupt aquatic ecosystems (National Standardization Agency.2016). One of the efforts to treat liquid waste in palm oil mills can be done by aeration process. The aeration process aims to increase the level of dissolved oxygen (DO) in liquid waste so that aerobic microorganisms can effectively degrade organic matter. The aeration process can be carried out by several methods, such as using an aerator (Fitri, A., Susanto, H., & Budiaman, I. G. S. 2017).)Dissolved Oxygen (DO) Increased from 0 hours to 3.9 Mg/l, 24 hours to 5.7 Mg/l and 72 hours to 6.3 Mg/l. PH Increased from 0 hours to 4.32, 24 hours to 4.78 and 72 hours to 5.32 So the increase in DO and PH during the Aeration process is very helpful in reducing the level of pollutants in palm oil mill waste The effectiveness of the aerobic aeration process in the treatment of palm oil mill waste is able to reduce the level of TSS, COD, BOD, for TSS at 0 hours 461 m/L, 24 hours 403 m/L ,72 hours 275 m./L for COD at 0 hours 4240 m/L 24 hours 3816 m/L ,72 hours 1018 m/L for BOD at 0 hours 506 m/L, 24 hours 358 m/L ,72 hours 298 m/L.
