Abstract

Mattirodeceng is a village located in Pinrang Regency, which has considerable natural resource potential in coconut production. But the utilization of coconut plants, especially the water of coconut, is still low. Coconut water only used for consumption purposes at certain times. The purpose of this activity is to provide training on the benefits and ways of processing coconut water into soy sauce for PKK groups in the Mattirodeceng village. The method used in this activity consisted of the pre-activity stage, which included a survey of the location and trial making of soy sauce made from coconut water. The implementation of activities carried out by counseling methods and training on the benefits and ways of processing coconut water into soy sauce. The result of the application of this activity was an increase in participants' knowledge about coconut water, namely its nutritional content, and its processed products in the form of soy sauce. The Organoleptic test showed the level of panelists' preference for taste, flavour, texture, and color showed good results, where all panelists liked the coconut water soy sauce products   Keywords: Coconut water, soy sauce, organoleptic Mattirodeceng Village.   ABSTRAK Mattirodeceng merupakan salah satu desa yang terletak di Kabupaten Pinrang yang memiliki potensi sumber daya alam yang cukup besar dalam produksi kelapa. Namun pemanfaatan tanaman kelapa, terutama air kelapa masih rendah. Air kelapa hanya digunakan untuk keperluan konsumsi pada saat-saat tertentu. Tujuan dari kegiatan ini yaitu untuk memberikan pelatihan manfaat dan cara pengolahan air kelapa menjadi kecap kepada kelompok PKK di desa mattirodeceng. Metode yang digunakan dalam kegiatan ini terdiri dari tahap pra kegiatan yang meliputi survei lokasi dan uji coba pembuatan kecap air kelapa. Tahap pelaksanaan kegiatan dengan metode penyuluhan dan pelatihan tentang manfaat serta cara pengolahan air kelapa menjadi kecap. Hasil dari pelaksanaan kegiatan ini adalah meningkatnya pengetahuan peserta tentang air kelapa, yaitu kandungan gizinya, dan produk olahannya berupa kecap. Hasil uji organoleptik menunjukkan tingkat kesukaan panelis terhadap rasa, aroma, tekstur dan warna menunjukkan hasil yang baik, dimana seluruh panelis menyukai produk kecap air kelapa.   Kata kunci: Air kelapa, kecap, organoleptik, Desa Mattirodeceng.

Abstract

Mining activities with an open system trigger land degradation which results in a decrease in land quality. The decline in land quality is related to the level of fertility and soil chemical properties, so that in general ex-mining land contains low nutrients. These problems in several mining companies that implement environmental sustainability are resolved through reclamation activities. This reclamation activity needs to be assessed, to measure the success of the mine in overcoming land degradation problems. In this study we demonstrate an assessment of the success of mine reclamation in the largest nickel mining area in South Sulawesi, using remote sensing technology. Formulation of NIR and Red bands on Sentinel 2 imagery can produce Normalized Difference Vegetation Index index. From the vegetation index value, it is known that the observed reclamation area is close to the high vegetation index value (0.7 - 0.9). This value is actually close to the vegetation index value in the surrounding natural forest, but with a low percentage of area. The distribution of the results of the assessment of plant growth in the reclamation area was lowest vegetation by 3.14%; lower vegetation by 12.15%; low vegetation by 21.53%; moderate vegetation by 14.82%; high vegetation by 25.94% and higher vegetation by 22.42% of the total reclamation area.

Abstract

Large scale land-based investments have a significant impact on natural resources and environmental conditions. It is necessary to protect areas of high conservation value (HCV) within land management investments, such as the mining sector, to minimise this impact. The existence of high conservation value sites in locations with activities related to the mining sector is intended to maintain the ecological and conservation value of a mining investment area. We demonstrate a model that can identify potential high conservation value sites in mining areas using remote sensing data and spatial analysis compiled with field observation data. The research was conducted in one of the largest nickel mining areas (71,047 ha) in South Sulawesi, Indonesia. We mapped vegetation density using the normalized difference vegetation index (NDVI), calculated from Sentinel-2 imagery. We also collected biodiversity data in predetermined inventory sampling plots, which we then used to estimate species richness using the Shannon-Wiener diversity index. Using a linear regression model to compare the normalized difference vegetation index value in each sampling plot with the biodiversity value of flora and fauna, we then estimated biodiversity distribution patterns for the entire study area. We found that potential high conservation value areas (areas likely to have high biodiversity based on our regression model) covered 40,000 ha, more than half of the total concession area.

Abstract

Nanopartikel Zink Oksid (ZnO-NP) merupakan suatu material yang dapat digunakan sebagai nanoplatform dalam sistem penghantaran obat sekaligus pencitraan biologis karena karakteristiknya yang unik. Penelitian ini bertujuan untuk mensintesis serta mengevaluasi pengaruh inkorporasi dua dopant (co-doping) magnesium (Mg2+) dan besi (III) (Fe3+) terhadap karakteristik optik dan struktur dari ZnO-NP. ZnO-NP (tanpa dopan, dengan dopan tunggal dan dengan dopan kombinasi) disintesis lewat jalur kimiawi dengan menggunakan metode ko-presipitasi sederhana. Larutan Zink Klorida dalam air digunakan sebagai material awal dan diendapkan dengan menambahkan Natrium Hidroksia dengan perbandingan molar 1:2. Sampel dikarakterisasi dengan menggunakan spektrofotometer UV-Visible dan Powder X-Ray Diffractometer (P-XRD). Hasil analisis sifat optik menunjukkan serapan maksimum sampel berada pada kisaran 361- 367 nm dan kalkulasi nilai bandgap berdasarkan data serapan tersebut berada pada rentang 3,09-3,23 eV. Difraktogram sampel menunjukkan sampel yang terbentuk adalah ZnO-NP dengan struktur kristal hexagonal wurtzite. Dari data difraktogram yang diperoleh, besar ukuran butir diestimasi dengan beberapa persamaan dan diketahui rentang diameter kristal berada pada kisaran 17,25 hingga 27,74 nm. Dari hasil penelitian ini dapat ditarik kesimpulan bahwa inkorporasi dopan Mg2+/Fe3+ mempengaruhi karakteristik ZnO-NP. Perubahan karakterisik ini dapat mempengaruhi performa nanomaterial ini sebagai agen teranostik.

Abstract

Sea worms have enormous potential to be used as alternative food ingredients because they have a fairly high protein content. The Research of the analysis yield and phytomomic compounds of Eunice Siciliensis marine worms has never been done. An effort to develop Eunice siciliensis sea worm-based alternative food ingredients is important to do phytochemical screening. This study aims to identify phytochemical compounds found in Eunice siciliensis marine worms and find out their benefits for health. This study was analyzed descriptively. The results showed that extract yield was 17.97% and Eunice siciliensis sea worm extract contained alkalaoid, flavonoids, saponins, triterpenoids / steroids, and tannins.
