Abstract

Activities of phytoplankton culture needed to be supported by physical and chemical parameters. This study aimed to analyze the effect of a combination of salinity and Walne fertilizer on the population growth of Nannochloropsis sp on the laboratory scale. The method used in this study is an experimental method using CRD (Completely Randomized Design) experimental design with 2 factors, namely salinity and Walne fertilizer, and each factor is given 3 levels of treatment. The level value of each factor is combined to obtain 9 combinations with 3 replications to obtain a total of 27 experimental units. The results of measuring the water quality parameters show that the media conditions were in good condition: an average temperature of 21℃, an average pH of 7.6, and the LED light used is ±2,000 lux. The results showed no significant effect of the combination of salinity and Walne fertilizer on the population growth of Nannochloropsis sp. The best combination value was obtained in the S1W1 treatment with a combination of 15 ppt salinity and 0.5 mL Walne fertilizer dose, resulting in cell population density (4125x103 cells/mL). The second best was obtained in the S1W2 combination with 15 ppt salinity and 1 mL Walne fertilizer dose (3775x103 cells/mL).

Abstract

Stunting telah menjadi masalah kesehatan utama dan prioritas utama di Indonesia. Stunting merupakan salah satu bentuk kekurangan gizi kronis yang menyebabkan pertumbuhan anak lebih pendek dari usianya sehingga mengakibatkan kegagalan tumbuh dan berkembang pada anak balita (bayi bawah lima tahun). Mahasiswa sebagai agen perubahan dalam menjalankan pengabdiannya melaksanakan edukasi stunting melalui program kerja unggulan Kukerta Unri di Desa Kesumbo Ampai, Kecamatan Bathin Solapan, Kabupaten Bengkalis. Tujuan dari pengabdian ini adalah untuk mengedukasi masyarakat mengenai stunting dan pencegahan terhadap hal-hal yang akan berdampak pada stunting. Hasil dari penyuluhan ini menunjukkan bahwa pengetahuan masyarakat mengenai stunting masih minim sehingga perlu adanya cakupan, jangkauan dan perhatian yang lebih luas pada desa. Untuk itu diharapkan pemerintah memberikan pelatihan khusus kepada kader posyandu agar dapat menjadi mata rantai penyuluhan menuju target posyandu itu sendiri yaitu mewujudkan desa bebas stunting.

Abstract

Tujuan pengabdian kepada masyarakat adalah untuk meningkatkan nilai ekonomi kelompok konservasi Laskar Mandiri yang mengelola kawasan mangrove Sungai Bersejarah Permai melalui pemanfaatan buah mangrove yang ada sebagai bahan baku beraneka ragam kue dan sirup di Desa Kayu Ara permai Kecamatan Sungai Apit Kabupaten Siak. Metode yang digunakan dalam melaksanakan kegiatan pengabdian kepada masyarakat ini adalah ceramah, diskusi dan praktek tentang semua rangkaian pengolahan buah dan daun mangrove untuk menjadi beraneka kue dan sirup dengan melibatkan secara langsung semua tim pengabdian meliputi dosen, mahasiswa Belukap Mangrove Club dan mahasiswa kukerta UNRI tahun 2021. Untuk mengetahui pemahaman peserta terhadap materi yang disampaikan dilakukan evaluasi dengan meminta peserta mengisi kuisioner sebelum dan setelah kegiatan dilakukan dan dibandingkan. Data yang diperoleh dianalisis secara deskriptif. Hasil kegiatan pengabdian ini menunjukkan bahwa seluruh peserta mengikuti rangkaian kegiatan dengan baik dari awal sampai akhir. Peserta terlibat langsung dalam praktek membuat makanan dan minuman olahan buah mangrove. Peserta pengabdian dapat memahami tentang materi yang disampaikan dengan baik. Sebanyak 15% peserta sudah mengetahui bahwa buah pedada dapat diolah menjadi sirup, namun 100 % peserta belum pernah mengetahui bahwa buah api api dapat diolah menjadi berbagai makanan seperti bolu dan klepon, demikian juga halnya dengan mengolah daun jeruju menjadi keripik. Seluruh peserta (100 %) sebelum adanya pengabdian dilakukan belum ada yang melakukan pengolahan buah mangrove, baik buah api api, buah pedada maupun daun jeruju. Artinya seluruh peserta (100 %) baru melakukan pengolahan buah mangrove melalui kegiatan pengabdian ini. Kegiatan pengabdian ini telah berjalan dengan baik yang ditandai dengan seluruh peserta dapat melakukan pengolahan buah mangrove langsung di bawah arahan tim pengabdian menjadi beraneka kue.

Abstract

Ketahanan pangan merupakan salah satu permasalahan yang sedang marak di Indonesia, hal ini dikarenakan masih banyaknya daerah-daerah di Indonesia yang mengalami kesenjangan mendasar dalam menciptakan lingkungan yang berwawasan maju, pengelolaan ketersediaan pasokan sumberdaya alam daerah (avaibility), serta keterjangkauan harga pangan (affordability). Budikdamber merupakan suatu kegiatan budidaya yang ramah lingkungan dimana mengsinergikan antara budidaya ikan dan tanaman pada satu wadah dalam skala kecil yang menghasilkan produk pertanian untuk kebutuhan nutrisi esensial seperti protein. Metode budidaya ikan di dalam ember atau budikdamber ini dapat di aplikasikan di rumah dengan memanfaatkan lahan yang terbatas guna menjaga ketersediaan pangan dan gizi seimbang yang cukup untuk masyarakat. Desa Bathin Sobanga merupakan salah satu desa yang pemanfaatan lahan dan ketahanan pangannya masih minim dikarenakan tidak sedikit masyarakat Desa Bathin Sobanga menginovasikan lahan yang sempit untuk suatu kegiatan seperti perkebunan sayur dan buah-buahan, namun kegiatan perkebunan tersebut tidak diterapkan secara keseluruhan oleh masyarakat Desa Bathin Sobanga karena tidak semua masyarakat desa memiliki lahan yang cukup. Melalui penyuluhan budikdamber ini diharapkan agar masyarakat lebih terpadu dan upgrade dalam teknik budidaya yang lebih ekonomis dan ramah lingkungan serta dapat memberikan inovasi dan informasi kepada masyarakat dalam pemanfaatan lahan terbatas, peningkatan ketahanan pangan rumah tangga, pemenuhan gizi seimbang, maupun meningkatkan ekonomi masyarakat.

Abstract

Mushroom coral (Fungiidae) is one of the families of hard corals (scleractinian) that live off the substrate (free-living), and most of the mushroom coral habitat is found on the reef slope, which has a substrate of broken coral. This study aimed to analyze the abundance and diversity and determine the differences in abundance of mushroom corals at different depths. This research was conducted in March 2024 in Pasumpahan Island, West Sumatra. This study used the survey method and belt transect method. The sampling location was divided into three stations consisting of 3 sampling points. Station I is located in the tourist area, Station II is in the dock area, and Station III is in the area facing the open sea. The results showed that the highest abundance based on depth was found at station III with a depth of 7 m, namely 4357.14 ind/Ha and the lowest abundance at station II with a depth of 5 m, namely 1285.71 ind/Ha. The t-test results obtained a significant value of less than 0.05, namely 0.048, which means that the abundance of mushroom corals at different depths is significantly different. The diversity index ranges from 1.930 to 2.013, which shows that the level of diversity of mushroom corals in the waters of Pasumpahan Island is classified as moderate

Abstract

Oil pollution in the waters is one factor affecting the abundance of phytoplankton, especially the diatoms. The waters of Bengkalis Strait, Pangkalan Jambi Village, and Bengkalis Regency are used as international shipping lanes and industrial areas. This study aims to analyze the total oil content, calculate the abundant of planktonic diatoms, and explain the relationships between the total oil content and the abundant of planktonic diatoms carried out in the Bengkalis Strait, Pangkalan Jambi Village Bengkalis Regency, Riau Province. This research uses a survey method. Station 1 is near fish ponds and mangroves, station 2 is in the harbor where the fishing boats moor, station 3 is in wharf bridge and residential areas, and station 4 is in mangrove ecotourism. The result of the oil content analysis obtained an average value of 0.216 ppm. The highest oil content at station 2 is 0.5742 ppm, and the lowest at station 4 is 0.0775 ppm. The calculations of the abundance of planktonic diatoms ranged from 3,323.28 to 11,631.48 ind/L. The highest abundance at station 3 was 9,692.2 ind/L. The lowest abundance was at Station 2, which was 4,154.1 ind/L. Simple linear regression test results obtained equation Y = 6045.927572 + (3013.071268x). The coefficient of determination (R2) = 0.049 states that 4.9% of the abundance of planktonic diatoms is influenced by oil content, and other environmental factors influence the rest. The correlation coefficient (r) = 0.0223, so the relationship between total oil content and the abundance of planktonic diatoms is very weak.
