Abstract

The amount of plastic waste, especially disposable plastic bottle waste (PET), needs to be utilized. plastic bottle waste is a flexible material that can be used as an alternative additive to the pavement mixture so as to reduce the production of PET disposable bottle waste. So this research needs to be done to find out its utilization. The purpose of this research is to analyze Polyethylen Terephtalate (PET) plastic bottle waste can be used as an additive and analyze the amount of Polyethylen Terephtalate (PET) bottles needed for Asphalt Concrete Wearing Course (AC-WC) pavement mixtures. The method used is an experimental method carried out in two stages. The first stage of Marshall testing without using plastic to find the Optimum Asphalt Content (KAO) with variations of 4%, 4.5%, 5%, 5.5%, 6%, 6.5%. The second stage of Marshall testing using the optimum asphalt content (KAO) obtained from stage one with additional variations of Polyethylen Terephtalate (PET) plastic bottle waste 1%, 2%, 3%, 4%, 5% to get the optimum PET content. The results of stage one Marshall testing obtained an optimum asphalt content of 5.675%, while Marshall in the second stage obtained an optimum PET content of 0.45% equivalent to 0.0026 gr and all types of Marshall parameters met the Bina Marga 2018 revision 2 specifications for mixing Asphalt Concrete Wearning Course (AC-WC). Each production of one ton of Asphalt Concrete Wearning Course (AC-WC) requires 204.3 bottles of Polyethylen Terephtalate (PET) plastic.The amount of plastic waste, especially disposable plastic bottle waste (PET), needs to be utilized. plastic bottle waste is a flexible material that can be used as an alternative additive to the pavement mixture so as to reduce the production of PET disposable bottle waste.

Abstract

This study investigates the implications of population growth and the conversion of paddy fields on rice food security in Gorontalo Province, Indonesia, during 2018–2023. Employing a quantitative descriptive research design with panel regression analysis, the research examines the relationship between population growth, paddy field conversion, and rice food security as a dependent variable. The findings reveal that both population growth and paddy field conversion significantly and positively influence rice food security. Population growth raises demand for rice, while paddy field conversion threatens production capacity, intensifying food security challenges. The results suggest that addressing land-use changes and managing population growth are crucial for maintaining sustainable food availability. This study contributes to understanding the dynamics of food security and provides recommendations for policymakers to design effective strategies in balancing population needs, agricultural sustainability, and economic development in Gorontalo.

Abstract

Abstrak: Strategi Pengelolaan Limbah Cair Industri Kecil Menengah di Kabupaten Gorontalo Utara. Saat ini Kabupaten Gorontalo Utara memiliki 508 Industri Kecil Menengah. IKM berpotensi menimbulkan dampak negatif melalui limbah yang dihasilkan. Pemerintah Kabupaten Gorontalo Utara telah melakukan antisipasi terhadap segala dampak negatif yang ditimbulkan oleh aktivitas IKM salah satunya dengan mengeluarkan peraturan bupati (PERBUP) Nomor 9 Tahun 2015. Namun kebijakan ini belum efektif diberlakukan. Penelitian ini bertujuan, 1) menganalisis kualitas limbah cair industri kecil menengah di Kabupaten Gorontalo Utara, 2) menentukan strategi kebijakan pengelolaan limbah cair industri kecil menengah di Kabupaten Gorontalo Utara. Metode pengumpulan data dilakukan secara sampling dengan cara mengambil sampel limbah cair di lapangan dan wawancara terhadap pengelola IKM. Data yang diukur meliputi Suhu, pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solid (TSS). Selanjutnya untuk menganalisis strategi pengelolaan limbah cair IKM di Kabupaten Gorontalo Utara, digunakan metode SWOT dengan menganalisis kondisi internal dan kondisi eksternal pengelolaan limbah cair di IKM. Hasil Analisa laboratorium menunjukkan Konsentrasi BOD, COD, TSS pada IKM tahu dan minyak kelapa berada diatas baku mutu yang mengancam kelangsungan biota perairan dan Kesehatan manusia. Antisipasi terhadap hal ini adalah limbah cair yang dihasilkan harus dapat diolah kembali menjadi bahan yang bernilai ekonomi tinggi Abstract: Management Strategy of small and medium enterprises waste pollution in Gorontalo Regency. North Gorontalo Regency has 508 Small and Medium Enterprises (SME’s) that have the potential negative affects through the waste their produce. The government of North Gorontalo Regency has anticipated the negative impacts caused by SME activities through PERBUP No 9 2015. However, this policy has not been effectively implemented. This study aims to 1) analyze the quality of small and medium enterprises liquid waste in North Gorontalo Regency, 2) determine policy strategies for managing small and medium industrial waste pollution in North Gorontalo Regency. The method of collecting data is by taking samples of liquid waste in the field and interviews with IKM managers. The data measured include Temperature, pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total suspended Solid (TSS). Furthermore, to analyze the SME liquid waste management strategy in North Gorontalo Regency, the SWOT method was used by analyzing the internal conditions and external conditions of liquid waste management in SME. The results of the laboratory analysis showed that the concentrations of BOD, COD, TSS in SME tofu and coconut oil were above the quality standard which threatened the survival of aquatic biota and human health. The anticipation of this is that the liquid waste produced must be reprocessed into materials of high economic value

Abstract

                                               ABSTRAK Aktivitas penambangan oleh masyarakat di sempadan Sungai Paguyaman, menyebabkan pencemaran di perairan sungai. Dampak langsung dapat dilihat pada kualitas perairannya. Tujuan penelitian ini adalah untuk menganalisis kualitas air Sungai Paguyaman pada areal penambangan batuan Desa Motoduto Kecamatan Boliyohuto. Penelitian ini dilakukan pada tahun 2022 di Sungai Paguyaman. Pengambilan sampel air di dilakukan di tiga tempat yaitu sebelum lokasi tambang sebagai kontrol, di tapak kegiatan tambang liar saat beraktivitas dan setelah lokasi pertambangan. Paremeter kualitas air meliputi parameter kecerahan, pH,  dan Dissolved Oxygen (DO). total dissolved solid (TDS), Total Suspended Solid (TSS), suhu dan ammonia, Biologycal Oxygen Demand (BOD) dan Chemical Oxygen Demand (COD). Hasil pengukuran akan ditampilkan dalam bentuk grafik dan dibahas seacara deskriptif dengan merujuk pada baku mutu PP Nomor 22 tahun 2021 (Lampiran VI). Hasil analisis laboratorium menunjukkan bahwa parameter TSS dan Surfactan melewati baku mutu kualitas air untuk Kelas II. Konsentrasi TSS di lokasi control sebesar 98 mg/l dan Surfactan 0,009 mg/l. Konsentrasi TSS di sekitar lokasi tambang sebesar 119 mg/l dan Surfactan 0,02 mg/l. Konsentrasi TSS setelah lokasi tambang adalah 148 mg/l dan Surfactan  sebesar 0,021 mg/l. Baku mutu TSS untuk air sungai Kelas II sebesar 50 mg/l dan Surfactan sebesar 0,001 mg/l.ABSTRACT Rock mining activities on the Paguyaman River border can cause river water pollution. The purpose of this study was to analyze the water quality of the Paguyaman River around the rock mining area of Motoduto Village, Boliyohuto District. Water sampling was carried out at three locations, namely before the mine site as a control, at the rock mining activity site and after the mining site. Water quality parameters include brightness, pH, and Dissolved Oxygen (DO) parameters. total dissolved solid (TDS), Total Suspended Solid (TSS), temperature and ammonia, Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). The measurement results will be displayed in graphic form and analyzed descriptively by referring to the PP No. 22 of 2021 quality standard (Appendix VI). The results of the laboratory analysis showed that the TSS and Surfactant parameters passed the water quality standard for Class II. The concentration of TSS at the control location was 98 mg/l and surfactant 0.009 mg/l. The concentration of TSS around the mine site is 119 mg/l and Surfactan is 0.02 mg/l. The concentration of TSS after the mine site is 148 mg/l and Surfactan is 0.021 mg/l. The TSS quality standard for Class II river water is 50 mg/l and Surfactant is 0.001 mg/l.
