Abstract

Availability of vessel design and capacity according to the wishes of fishermen groups on a small scale,especially in the area of South Buton Regency must be carried out. Taking into account the cost of makingships and the use of fiberglass materials, it is hoped that a ship design will be produced that is for accordancewith the wishes of the community. The main ship size study provides many options in choosing ships withdifferent characteristics but having almost the same ship volume. This study aims to identify and compareseveral main ship sizes that are designed and provide choices according to existing requirements. The resultsshowed that with a ship length of 7 m, width of 1.5 m, and of 0.72 m, the ship would have a resistance of 2.8kN, a power of 14.22 kW and a displacement of 1464 kg and a surface area of 226854.22 cm2. Meanwhile,with a ship length of 7.25 m, width of 1.5 m, and of 0.70 m, it will have a resistance of 2.9 kN, a power of 14.7kW and a displacement of 1474 kg and a surface area of 232578.12 cm2. Whereas with a ship length of 7.50 m,width of 1.5 m, and of 0.68 m it will have a resistance of 1.6 kN, a power of 15.22 kW and a displacement of1481 kg and a surface area of 238195.85 cm2.

Abstract

Kegiatan pengabdian kepada masyarakat (PkM) ini dilakukan sebagai upaya untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam mengelola sampah organik yang berasal dari rumah tangga menjadi eco enzyme. Eco enzyme adalah cairan alami serbaguna hasil fermentasi dari campuran sisa sayuran/buah, gula, dan air. Kegiatan PkM dilakukan di desa Tanailandu Kecamatan Mawasangka Kabupaten Buton Tengah pada tanggal 01 Mei 2023, yang ditujukan kepada ibu rumah tangga yang tergabung dalam Kelompok Pemberdayaan Kesejahteraan Keluarga (PKK) Desa Tanailandu. Tujuan dari Pkm ini adalah untuk mentransfer pengetahuan dan teknik pengolahan sampah organik menjadi eco enzyme dan memotivasi masyarakat untuk berpartisipasi dalam pelestarian lingkungan. Pelaksanaan Pkm dilakukan melalui tiga tahapan yaitu observasi awal dan koordinasi dengan pemerintah Desa Tanailandu tentang pelaksanaan kegiatan, sosialisasi materi eco enzyme dan praktik pembuatan eco enzyme. Kegiatan PkM berlangsung dengan lancar yang ditandai dengan apresiasi dan antusiasme peserta ibu PKK Desa Tanailandu selama melaksanakan kegiatan pembuatan eco enzyme.

Abstract

Keamanan pangan merupakan aspek penting dalam mendukung kesehatan masyarakat, khususnya pada produk hortikultura yang dihasilkan melalui sistem hidroponik. Salah satu potensi risiko yang perlu diantisipasi adalah paparan logam berat yang dapat mencemari media tanam. Kegiatan pengabdian ini bertujuan untuk memberikan edukasi tentang bahaya logam berat pada sayuran hidroponik serta memberikan pendampingan uji logam berat pada pelaku usaha pertanian hidroponik Say Your Green di Kolaka. Metode yang digunakan meliputi penyuluhan interaktif berbasis media poster edukasi serta pengujian ekperimetal di laboratorium untuk analisis kadar logam timbal (Pb) pada salah satu komoditi sayuran segar hidroponik (seledri) menggunakan instrumentasi ICP-OES (Induktif Coupled Plasma Optical Emission Spectrometry). Hasil kegiatan pengabdian ini telah menunjukkan perkembangan yang cukup signifikan terkait wawasan logam berat pada pelaku usaha pertanian sayuran hidroponik terutama aspek regulasi dan pengujian logam berat pada sayuran. Hasil analisis logam berat pada sayuran hidroponik seledri kebun Say Your Green menunjukkan bahwa sampel yang dianalisis tidak mengandung logam berat Pb, sehingga produk sayuran hidroponik dari kebun Say Your Green relatif aman dikonsumsi. Dengan adanya edukasi dan pendampingan uji logam berat ini, diharapkan usaha hidroponik Say Your Green mampu menjaga kualitas produknya dan meningkatkan kepercayaan konsumen terhadap keamanan pangan yang dihasilkan.

Abstract

Kelompok nelayan di kabupaten Konawe Kepulauan menghadapi kendala berupa keterbatasan pemahaman dan keterampilan terkait fabrikasi dan perbaikan kapal fiberglass. Kondisi ini berdampak pada peningkatan biaya operasional yang mengurangi pendapatan nelayan. Pelatihan ini bertujuan untuk menambah pengetahuan bagi nelayan dalam hal proses pengerjaan kapal fiberglass berupa pembuatan cetakan, pengenalan material fiberglass, metode pengerjaan kapal fiberglass dan hal-hal lain yang berhubungan pengerjaan kapal fiberglass. Metode pelatihan dengan menggunakan pendekatan metode on the job training yang dilakukan dengan ceramah dan praktik langsung di lapangan. Hasil kegiatan pelatihan berupa tercetaknya sebuah cetakan kapal yang berukuran kecil 5 GT yang sekaligus akan menjadi aset nelayan dalam melaksanakan pengadaan kapal berikutnya, proses pelatihan ini juga menambah wawasan pada kelompok nelayan di wilayah Kabupaten Konawe Kepulauan dalam hal pengetahuan tentang bahan fiberglass sebagai bahan dasar pembuatan kapal fiberglass dan peningkatan keterampilan nelayan pada proses pembuatan kapal secara umum. Pelatihan seperti ini diharapkan selalu dilaksanakan untuk setiap kelompok nelayan di kecamatan lain di wilayah Konawe Kepulauan.

Abstract

Susube (Meistera aculeata (Roxb.) Škorničk. & M.F.Newman) is one of the species of the zingiberaceae family that grows in Southeast Sulawesi, especially in Konawe Regency. The fruit of this plant is often consumed and used as a cooking spice by the native. Meanwhile, the compounds content and bioactivity of the rhizome and fruit which is a characteristic of the Zingiberaceae family, has never been reported. Therefore, this study aimed to identify compounds contained in the rhizome along with their antioxidant and cytotoxic properties. The research method used is experimental research, starting with qualitative phytochemical screening in ethanol exctract and then continued with antioxidant (1,1-diphenyl-2-picrylhydrazyl or DPPH) and cytotoxicity assay (Brine Shrimp Lethality Test or BSLT). The results of the phytochemical screening indicate that the ethanol extract of the Susube rhizome and fruit contains alkaloids, flavonoids, tannins, terpenoids, and saponins. Antioxidant activity was determined based on the ability to reduce DPPH radicals and was calculated by determining the IC50 value, while toxicity was assessed based on shrimp larvae mortality and calculated by determining the LC50 value. The study results show that the IC50 values for the ethanol extract of Susube rhizome, fruit and the positive control ascorbic acid are 4.9 µg/mL, 4,5 µg/mL and 2.2 µg/mL, respectively. Meanwhile, the LC50 values for the ethanol extract of Susube rhizome, fruit, and the positive control potassium bichromate are 578 µg/mL, 958 µg/mL, and 2.8 µg/mL, respectively. Based on these results, it can be concluded that the ethanol extract of Susube rhizome and fruit (Meistera aculeata (Roxb.) Škorničk. & M.F.Newman) exhibits toxic effects on shrimp larvae (≤1,000 mg/L). Additionally, its ethanol extract shows very strong antioxidant effects in scavenging DPPH free radicals. Therefore, this study suggests that the Susube rhizome and fruit extract warrants further investigation as a promising candidate for treatment or prevention of diseases, supporting the potential of Southeast Sulawesi's local natural resources for phytopharmaceutical or herbal medicine

Abstract

Sediment Microbial Fuel Cell (MFC) is a technology that can convert chemical energy into electrical energy through the process of nutrient degradation by microbes. Sediment taken from the bottom of shrimp ponds was added as a source of microbes, while fish and shrimp wastewater were used as a source of nutrients for microbes. This study aims to measure the performance of the SMFC system on fish effluent and shrimp effluent to produce bio-electricity while reducing the waste load. The research method was experimental laboratories. The treatment given was the different types of electrodes, namely zinc-copper and aluminum-copper. In addition, 0.2 M KMnO4 electrolyte solution was used. This study consisted of four stages: the manufacture of nutrients from fish and shrimp wastewater, the manufacture of a dual chamber MFC bioreactor, the measurement of electrical values, and the analysis of waste quality. Experiments were carried out for 30 days by measuring electricity every 24 hours. The average value of electricity generated in the nutrients of fish wastewater with Zn/Cu electrodes was 0.705 V and Al/Cu was 0.472 V. Meanwhile, the average value of electricity in shrimp wastewater nutrients with Zn/Cu electrodes was 0.630 V and Al/Cu was 0.625 V. The number of colonies after adding sediment in the shrimp wastewater sample were 8.9 x 106 CFU/mL, the fish wastewater sample was 9.5 x 106 CFU/mL. It indicates the presence of microorganisms that play a role in the SMFC system
