Abstract

Naturally, the human body has tolerance to free radical attacks. However, the natural antioxidant ability will decrease when exposure to free radicals from within and outside the body occurs intensively. Antioxidants play potential preventive role to protect the body from damage associated with oxidative stress by free radicals. One of the potential marine resources used as an antioxidant is macroalgae. Turbinaria is widely distributed in tropical waters of Indonesia, including West Kalimantan. This genus produces secondary metabolites with several biological activities. This genus abundantly grows in Kabung Island. However, it has not been used by the local community, even tends to be considered as a weed that disturbs others marine biota. This study aimed to evaluate the potential antioxidant activity of tropical brown macroalgae Turbinaria ethanol extract from Kabung Island, West Kalimantan. antioxidant activity was evaluated using the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenger method with UV-vis spectrophotometer. The result showed that the ethanolic extract had a high of potential antioxidant activity which IC50 was 87.31 mg/L and it was classified into strong antioxidant potential.

Abstract

Xestospongia sp. is a barrel sponge belonging to the phylum porifera of the class Demospongia. This sponge abundant in coral reefs ecosystem. It is a filter feeder where the filtering of nutrients available in the environment occurs in the pores along the body. Various microorganisms in the seawater were exposed to sponges, so that they can produce various biological activities. This study aims to determine the antioxidant activity of crude protein from sponge Xestospongia sp from Spermonde waters of Sulawesi Island. The protein of the sponge was extracted using ammonium sulfate. Then, the protein was determined by the Lowry method in each fraction. Furthermore, the antioxidant activity was carried out by the DPPH method. The crude protein extracts in various fractions produced intermediate antioxidant activity produced from each fraction. They are fraction 1 (0-30%) of 81.31 ppm, fraction 2 (30-60%) was 180.22 ppm, and fraction 3 (60–90%) was 93.97 ppm, while crude protein was 128.33 ppm.The ascorbic acid as a positive control has antioxidant 2.98 ppm.

Abstract

Salah satu komoditas unggulan Kalimantan Barat di bidang holtikultura adalah buah Nanas dengan jumlah produksi sebesar 76.400 ton pada tahun 2019. Buah Nanas dijual dalam kondisi segar maupun berbagai jenis olahan. Pengembangan hasil olahan Nanas berpotensi memberikan kontribusi pada peningkatan volume sampah organik di Kalimantan Barat. Sampah menjadi isu global yang dapat mengakibatkan pencemaran lingkungan dan gangguan kesehatan manusia apabila tidak dikelola dengan baik. Hingga saat ini, penanganan sampah masih menjadi problematika yang belum terselesaikan. Slogan Reuse, Reduce dan Recycle (3R) telah menginspirasi masyarakat dalam melakukan pengelolaan sampah secara sistematis dan berkelanjutan. Kegiatan PKM ini bertujuan untuk menerapkan pemahaman dan meningkatkan skill sejak dini dalam pengelolaan limbah organik menjadi produk yang lebih bermanfaat bagi lingkungan. Sampah limbah Nanas dapat diolah menjadi produk yang memiliki nilai tambah dan bermanfaat. Kegiatan pelatihan dilaksanakan pada September 2022 dengan peserta siswa SMUN 3 Pontianak sebanyak 40 orang. Kegiatan dilaksanakan dengan metode ceramah dan praktek membuat eco-enzyme. Sedangkan, evaluasi kegiatan dilaksanakan melalui kuis pada saat pre-test dan post-test, serta evaluasi keterampilan siswa dalam mempersiapkan proses fermentasi. Hasil penelitian yaitu pembuatan ekoenzim dilakukan dengan pencampuran bahan dengan perbandingan limbah kulit Nanas : gula aren : air sebesar 3 : 1 : 10. Fermentasi dilakukan ± 3 bulan. Kegiatan mandiri ini menunjukkan antusiasme dan semangat dari peserta mengikuti seluruh proses kegiatan. Selain itu, peserta menjadi lebih terampil dalam mengolah limbah menjadi larutan ekoenzim. Training and Socialization of Pineapple Peel Waste Fermentation to Eco-enzyme as the Implementation of the Slogan Reuse, Reduce dan Recycle  One of the featured commodities of West Kalimantan in the horticulture sector is Pineapple with a total production of 76,400 tons in 2019. Pineapple is sold in the form of fresh or in various types of processing. The development of processed pineapple has the potential to contribute to increasing the volume of organic waste in West Kalimantan. Garbage is a global issue that cause environmental pollution and human health problems if not managed properly. Until now, waste management is still an unresolved problem. The slogan Reuse, Reduce and Recycle (3R) has inspired the community to carry out waste management systematically and sustainably. This community services aimed to apply understanding and improve skills in managing organic waste into useful products to the environment. Pineapple waste can be processed into products that have an added value and useful. The community service activity was carried out in September 2022 with participants from SMUN 3 Pontianak as many as 40 students. Activities were carried out with the lecture method and practice of making eco-enzymes. Meanwhile, evaluation was done through quizzes during the pre-test and post-test, as well as evaluating students' skills in preparing for the fermentation process. The result showed that the production of eco-enzymes was done by mixing the ingredients with a ratio of pineapple waste: palm sugar: water of 3 : 1 : 10. Fermentation was carried out for ± 3 months. This activity showed the enthusiasm of the participants to attend in the whole process of this activity. In addition, the skill of the participants was increased in processing organic waste into an eco-enzyme

Abstract

Demam Berdarah Dengue (DBD) ditularkan melalui gigitan nyamuk Aedes aegypti, menjadi ancaman serius di banyak negara tropis dan subtropis, termasuk Indonesia. Edukasi pencegahan DBD pada anak sekolah di wilayah Kalimantan Barat menjadi krusial mengingat tingginya angka infeksi di kalangan anak-anak dan dampaknya terhadap kesehatan serta aktivitas belajar mereka. Tujuan dari kegiatan Pengabdian kepada masyarakat (PKM) ini adalah untuk meningkatkan pengetahuan peserta didik SMPN 8 Kubu Raya tentang penyakit DBD meliputi pola penyebaran, gejala dan pencegahan serta pengobatannya. Kegiatan diikuti oleh 20 orang siswa, dilaksanakan dengan metode ceramah edukatif dan pengenalan tanaman zodia, lavender dan sereh wangi yang dapat digunakan dalam pencegahan penyakit DBD. Hasil evaluasi menunjukkan adanya peningkatan pengetahuan pada peserta kegiatan. Diharapkan program edukasi pada anak usia sekolahj dapat dilakukan secara periodik untuk meningkatkan kesadaran anak-anak, mendorong mereka untuk menjadi agen perubahan di rumah dan lingkungan sekitar. Reducing the Number of Dengue Fever Sufferers through the Active Role of Students at SMPN 8 Kubu Raya Dengue Hemorrhagic Fever (DHF), transmitted through the bite of the Aedes aegypti mosquito, is a serious threat in many tropical and subtropical countries, including Indonesia. Education on dengue prevention among school children in the West Kalimantan region is crucial considering the high number of infections among children and the impact on their health and learning activities. The aim of this Community Service (PKM) activity is to increase the knowledge of SMPN 8 Kubu Raya students about dengue fever including spread patterns, symptoms and prevention and treatment. The activity was attended by 20 students, carried out using an educational lecture method and an introduction to the zodiac plant, lavender and citronella which can be used to prevent dengue fever. The evaluation results showed an increase in knowledge among activity participants. It is hoped that educational programs for school-age children can be carried out periodically to increase children's awareness, encouraging them to become agents of change at home and in the surrounding environment.
