Abstract

The effect of submersion KOH 5% for seaweed as raw materials products air freshener gel has been studied. Seaweed in Indonesia has a big potentially and it is commonly used in food products, beverages, pharmaceuticals and cosmetics. This research aims to use seaweed as a feedstock gel air freshener. Soaking seaweed with KOH was conducted to determine the nature of the water content and gel strength of the gel air freshener products generated given the scent of oranges and cloves. KOH concentration used was 5%. The results showed the water content of seaweed with KOH soaked lower than without KOH, whereas the gel strength with marinated seaweed KOH higher than without KOH. The results of organoleptic test, in this case the sense of smell, the air freshener gel product indicates that the product that uses citrus scent perfuming/lemon, panelists preferred more than the product is scented gel air freshener clove oil.

Abstract

The change of Indonesia's capital from Jakarta to The Capital City of Nusantara (IKN) impacts population movement and must be supported by fulfilling basic needs. One of the basic needs is the availability of good quality clean water. This research aims to analyze the quality of raw water sources that will be used to provide the needs of IKN. Water quality analysis was carried out using the pollutant index method at 4 sampling locations along the Sepaku River, namely Lokdam Bridge (T1), Upstream Intake (T2), Sepaku VI Bridge (T3), and PDAM Intake (T4). The water quality parameters analyzed include pH, Dissolved Oxygen (DO), and Total Dissolved Solid (TDS). The pollutant index values at T1 (2.006), T2 (3.882), and T3 (3.849) are categorized as lightly polluted, so they require additional processes that they can be used as a raw water source, especially to fulfill the Central Government Core Area (KIPP) of IKN. Different results were shown at sampling locations along the Tengin River. Even though T4 (1.055) is included as lightly polluted, the pollutant index value decreased at T5 (0.802) and T6 (0.862) due to the self-purification ability. Thus, the Tengin River is considered to have met the requirements as a raw water source for drinking water. However, efforts are still required to maintain water quality in the future. Abstrak Pergantian Ibukota Indonesia dari Jakarta ke Ibu Kota Nusantara (IKN) berdampak pada perpindahan penduduk dan harus disertai dengan pemenuhan kebutuhan pokok salah satunya ketersediaan air bersih dengan kualitas yang baik. Penelitian ini bertujuan untuk menganalisis kualitas sumber air baku yang akan digunakan untuk pemenuhan kebutuhan masyarakat di IKN. Analisis kualitas air dilakukan menggunakan metode indeks pencemar pada 6 lokasi sampling di sepanjang Sungai Sepaku yaitu Jembatan Lokdam (T1), hulu intake (T2), Jembatan Sepaku VI (T3), Tengin Kanan (T4), Tengin Kiri (T5), dan intake PDAM (T5). Parameter kualitas air yang dianalisis mencakup pH, dissolved oxygen (DO), dan total dissolved solid (TDS). Nilai indeks pencemar pada T1 (2,006), T2 (3,882), dan T3 (3,849) dikategorikan tercemar ringan sehingga memerlukan proses pengolahan tambahan agar bisa dijadikan sebagai sumber air baku khususnya untuk pemenuhan Kawasan Inti Pusat Pemerintahan (KIPP) IKN. Hasil yang berbeda ditunjukkan pada lokasi sampling di sepanjang aliran Sungai Tengin. Walaupun T4 (1,055) termasuk kategori tercemar ringan, nilai indeks pencemar mengalami penurunan pada T5 (0,802) dan T6 (0,862) akibat kemampuan untuk melakukan penjernihan sendiri (self-purification). Sehingga aliran Sungai Tengin dianggap telah memenuhi syarat sebagai sumber air baku air minum. Meskipun demikian, tetap memerlukan upaya untuk menjaga kualitas airnya di masa mendatang.

Abstract

The relocation of the capital of Indonesia from Jakarta to the capital of the archipelago (IKN) has an impact on increasing the population. This increase in population is directly proportional to the increase in the need for clean water. This study aims to determine the carrying capacity of the IKN environment as the capital of a new country based on water availability and needs. The study was conducted by combining quantitative descriptive analysis by comparing the volume of water availability with community needs which results were then classified into water carrying capacity classes. Based on the calculation results, the estimated volume of water available at IKN reaches 712,020,738.75 m3 / year. With water needs for the community reaching 314,505,600.00 m3 / year, the value of water carrying capacity is 2.26 and is included in the category of conditional safe. The volume of water available at IKN is stated to be still able to meet the needs of the community. However, various efforts are needed to maintain the quantity and quality so as to meet the needs of the community in the long run.

Abstract

Abstrak Ciguatera Fish Poisoning (CFP) dan fenomena Marak Alga Berbahaya (MAB) yang disebabkan oleh dinoflagellata bentik beracun merupakan salah satu bencana ekologi atau lingkungan yang dapat mengancam kesehatan manusia di kawasan pesisir Indonesia, seperti di kawasan Taman Wisata Perairan (TWP) Gili Matra yang terdiri dari 3 pulau yaitu Gili Meno, Air, dan Trawangan. TWP Gili Matra merupakan pusat wisata bahari dan kawasan konservasi laut di kawasan Nusa Tenggara Barat yang diketahui mengalami tekanan akibat aktivitas manusia dari kegiatan pariwisata dan perikanan yang berdampak negatif kepada ekosistem pesisir, terutama terumbu karang. Kondisi tersebut dapat meningkatkan kelimpahan komunitas dinoflagellata bentik beracun yang berpotensi menyebabkan terjadinya CFP dan MAB di TWP Gili Matra. Untuk itu diperlukan upaya mitigasinya agar risiko bencana ekologi CFP dan MAB dikemudian hari yang selain dapat menyebabkan terjadinya kerusakan ekosistem perairan TWP Gili Matra, tetapi juga kerugian ekonomi yang cukup besar, tidak terjadi. Menurut perhitungan ekonomi para ahli, nilai ekonomi kegiatan pariwisata di TWP Gili Matra, mencapai 26,86 triliun rupiah per tahun.  Salah satu upaya mitigasi bencana ekologi CFP dan MAB adalah dengan mengetahui kondisi lingkungan perairan di TWP Gili Matra pada musim hujan. Berdasarkan hasil survei diketahui kondisi biofisikakimia lingkungan perairan pada musim hujan bulan Desember 2022 dan Maret 2024 dalam keadaan yang sangat baik dengan tingkat eutrofikasi sebagai indikator kualitas lingkungan perairan pada tingkat ultraoligotrofik dengan nilai skor TSI (Trophic State Index) 12,9-19,4 (<30) yang mengindikasikan bahwa kesuburan perairan sangat rendah, air jernih, konsentrasi oksigen terlarut tinggi sepanjang tahun dan mencapai zona hipolimnion.   Abstract Ciguatera Fish Poisoning (CFP) and the phenomenon of Harmful Algal Bloom (HABs) caused by toxic benthic dinoflagellates are one of the ecological or environmental disasters that can threaten human health in coastal areas of Indonesia, such as in the Gili Matra Aquatic Tourism Park (ATP) area which consists of three islands, namely Gili Meno, Air, and Trawangan. ATP Gili Matra is a center for marine tourism and conservation areas in the West Nusa Tenggara region which is known to be under pressure due to human activities from tourism and fisheries activities that have a negative impact on coastal ecosystems, especially coral reefs. This condition can increase the abundance of toxic benthic dinoflagellate communities that have the potential to cause CFP and HABs in ATP Gili Matra. For this reason, mitigation efforts are needed so the risk of CFP and HABs ecological disasters in the future which can not only cause damage to the ATP Gili Matra aquatic ecosystem, but also significant economic losses, does not occur. According to economic calculations by experts, the economic value of tourism activities in ATP Gili Matra reaches IDR 26.86 trillion per year. One of the efforts to mitigate the ecological disaster of CFP and HABs is to understand the condition of the aquatic environment in ATP Gili Matra during the rainy season. Based on the survey results, it is known that the biophysical and chemical conditions of the aquatic environment during the rainy season in December 2022 and March 2024 are in very good condition with the level of eutrophication as an indicator of the quality of the aquatic environment at the ultraoligotrophic level with a TSI (Trophic State Index) score of 12.9-19.4 (<30) which indicates that water fertility is very low, the water is clear, the concentration of dissolved oxygen is high throughout the year and reaches the hypolimnion zone.
