Keberlanjutan lingkungan menjadi perhatian utama dalam pengelolaan ruang terbuka hijau di kampus, salah satunya melalui program penanaman bibit pohon di Bukit Fakultas Pertanian Universitas Negeri Gorontalo. Bukit yang berada di Kawasan Fakultas Pertanian masih dalam kondisi terbuka tanpa penutupan lahan berupa vegetasi pohon, sehingga berpotensi untuk dilakukannya penanaman pohon guna mengurangi erosi permukaan tanah. Selain berfungsi sebagai pengendali erosi, keberadaan pohon-pohon juga memberikan manfaat tambahan menjadi naungan yang mendukung kenyamanan sekitar. Kegiatan ini bertujuan untuk melakukan penanaman bibit pohon di Bukit Fakultas Pertanian untuk keberlanjutan lingkungan kampus Universitas Negeri Gorontalo. Peserta kegiatan ini melibatkan 53 mahasiswa dan tim dosen Jurusan Agroteknologi Universitas Negeri Gorontalo. Metode kegiatan ini dilakukan dengan beberapa tahap yaitu tahap persiapan, tahap pelaksanaan dan tahap evaluasi. Hasil dari kegiatan pengabdian ini mahasiswa dapat memahami bahwa pohon memiliki manfaat ekologis yang menyeluruh dimulai dari akar hingga buah yang dapat dimanfaatkan secara langsung sebagai sumber pangan atau keanekaragaman hayati. Sehingga dengan melakukan penanaman pohon di wilayah kampus dapat meningkatkan pengetahuan dan keterampilan mahasiswa terkait teknik-teknik penanaman pohon yang benar. Dengan demikian, diharapkan kegiatan ini dapat meningkatkan keasrian, kenyamanan, dan keindahan lingkungan kampus khususnya di Fakultas Pertanian.

Freshwater crayfish (Cherax quadricarinatus) is a valuable aquaculture commodity with relatively easy cultivation. However, low larval survival during early developmental stages remains a major challenge in its farming. This study aims to evaluate the effects of dissolved glucose and amino acid combinations on growth characteristics, molting frequency, and survival rate. The research was conducted in the Greenhouse of the Faculty of Agriculture, Animal Husbandry, and Fisheries, Universitas Muhammadiyah Parepare, using hatchery-produced crayfish larvae. Four dosage combinations were tested: A) 100 ppm glucose + 250 ppm amino acids, B) 150 ppm glucose + 200 ppm amino acids, C) 200 ppm glucose + 150 ppm amino acids, and D) 250 ppm glucose + 100 ppm amino acids, each replicated three times. The results showed that glucose and amino acid combinations significantly affected crayfish length growth. The highest absolute length growth was observed in the 250 ppm glucose + 100 ppm amino acid group. Meanwhile, the 150 ppm glucose + 200 ppm amino acid combination showed the best performance in molting frequency, number of molting crayfish, survival rate, and percentage of surviving crayfish. The optimal treatment for supporting freshwater crayfish growth and development was the 150 ppm glucose + 200 ppm amino acid combination.Keywords:Cherax quadricarinatusGlucoseamino acidsgrowth characteristicssurvival ratemolting

Peningkatan produktivitas jagung sangat dipengaruhi oleh karakter fisiologi seperti klorofil dan stomata daun. Hal ini sangat berkaitan dengan proses fotosintesis yang dipengaruhi oleh kandungan nitrogen dan air dalam tanah. Penelitin ini bertujuan untuk mengetahui pengaruh penggunaan pupuk slowrelase dari biochar tongkol jagung berbasis NPK terhadap karakter dan kolerasi fisiologi tanaman jagung. Metode penelitian merupakan percobaan lapangan menggunakan Rancangan Acak Kelompok untuk menguji empat jenis perlakuan, yakni Pupuk kimia (P0), pupuk slowrelase berbasis NPK (P1), pupuk slowrelase diperkaya urin sapi (P2) dan pupuk slowrelase diperkaya urin sapi dan bakteri (azotobacter dan basillus)(P3). Parameter yang diamati terhadap karakter fisiologi tanaman jagung, yakni Chlorofil content Indeks (CCI), kehijauan daun, jumlah stomata dan ukuran stomata serta korelasi antar karakteri fisiologi. Hasil penelitian menemukan bahwa pemberian pupuk slowrelase diperkaya urin sapi dan bakteri memberikan hasil terbaik pada CCI dan kehijauan daun yakni 44,64 dan 3,77 berbeda nyata hingga sangat nyata dengan pemberian pupuk kimia (16,27; 2,77). Untuk tindak adaptasi pemberian pupuk slowrelease diperkaya urin sapi dan bakteri mengurangi jumlah ukuran stomata dengan hasil yang lebih kecil (78,33) berbeda nyata dengan pemberian pupuk slowrelease pengkayaan bakteri (P0,P1 dan P2). Terdapat korelasi yang nyata antara CCI dan jumlah stomata terhadap kehijauan daun. Berdasarkan hal tersebut, maka penggunaan pupuk slowrelase yang diperkaya urin sapi dan bakteri menjadi strategi adaptif usaha tani jagung menghadapi perubahan iklim. Increasing corn productivity is strongly influenced by physiological characters such as chlorophyll and leaf stomata. This is closely related to the photosynthesis process which is influenced by the nitrogen and water content in the soil. This research aims to use slow-relase fertilizer from NPK-based corn cob biochar on the characteristics and physiological correlation of corn plants. The research method was a field experiment using a Randomized Block Design to test four types of treatment, namely chemical fertilizer (P0), NPK-based slowrelase fertilizer (P1), slowrelase fertilizer enriched with cow urine (P2) and slowrelase fertilizer enriched with cow urine and bacteria (azotobacter and bacillus )(P3). Observation parameters on the physiological characteristics of corn plants, namely Chlorophyll content Index (CCI), leaf greenness, number of stomata and stomata size as well as correlation between physiological characteristics. The results of the research found that the application of slowrelase fertilizer enriched with cow urine and bacteria gave the best results in CCI and leaf greenness, namely 44.64 and 3.77, significantly to very significantly different from the application of chemical fertilizer (16.27; 2.77). For adaptation, giving slow-release fertilizer enriched with cow urine and bacteria reduced the number of stomata sizes with smaller results (78.33), significantly different from giving slow-release fertilizer enriched with bacteria (PO, P1 and P2). There is a real correlation between CCI and the number of stomata on leaf greenness. Based on this, the use of slowrelase fertilizer enriched with cow urine and bacteria is an adaptive strategy for corn farming to face climate change.

Analisis korelasi dan sidik lintas merupakan analisis statistik deskriptif untuk memahami hubungan langsung dan tidak langsung antar karakter morfologi. Penelitian ini bertujuan untuk mengetahui respon perendaman benih terhadap karakter amatan; menduga aksi gen yang mengendalikan karakter perkecambahan benih padi terhadap perendaman benih; memperoleh karakter amatan yang memiliki keeratan hubungan dengan karakter lainnya melalui nilai korelasi; dan mengetahui pengaruh langsung dan tidak langsung beberapa karakter amatan perkecambahan benih padi terhadap beberapa perlakuan perendaman benih. Penelitian ini dilaksanakan di Laboratorium Agronomi Fakultas Pertanian Universitas Negeri Gorontalo pada Bulan November 2024. Penelitian ini menggunakan rancangan faktorial dua faktor dalam RAL, dimana faktor pertama terdiri atas jenis perendaman yaitu tanpa perendaman, perendaman menggunakan air biasa, air kelapa, air panas suhu 40°C, dan ekstrak bawang merah. Sedangkan untuk faktor kedua yaitu durasi perendaman yang terdiri atas 5 menit dan 10 menit. Hasil penelitian menunjukkan perendaman benih berpengaruh nyata terhadap perkecambahan benih padi Var. Inpari Nutri Zinc yang dibuktikan dari nilai kuadrat tengah, dominansi karakter amatan dipengaruhi oleh aksi gen aditif dan epistasis komplementer dan dikendalikan oleh banyak gen, karakter panjang plumula dan radikula berkorelasi positif dan sangat kuat dengan karakter kadar air kecambah. Sementara bobot kering kecambah berkorelasi negatif dan berpengaruh sangat nyata terhadap kadar air kecambah; dan karakter bobot kering kecambah menghasilkan pengaruh langsung tertinggi serta karakter panjang radikula menghasilkan pengaruh tidak langsung tertinggi. Sehingga, karakter kadar air kecambah dan panjang plumula dapat digunakan sebagai karakter seleksi untuk uji perkecambahan benih padi menggunakan perlakuan perendaman benih. Correlation and cross-fingerprint analysis is a descriptive statistical analyses to understand the direct and indirect relationships between morphological characters. This study aims to determine the response of seed soaking to observed characters; predict the action of genes that control rice seed germination characters to seed soaking; obtain observed characters that have a close relationship with other characters through correlation values; and determine the direct and indirect effects of several observed characters of rice seed germination on several seed soaking treatments. This study was conducted at the Agronomy Laboratory, Faculty of Agriculture, Gorontalo State University in November 2024. This study used a two-factor factorial design in RAL, where the first factor consisted of the type of soaking, namely, without soaking, soaking using plain water, coconut water, hot water at 40°C, and shallot extract. The second factor is the duration of soaking, which consists of 5 minutes and 10 minutes. The results showed that seed soaking had a significant effect on the germination of rice seeds of Var. Inpari Nutri Zinc, as evidenced by the mean square value, the dominance of observed characters is influenced by additive gene action and complementary epistasis, and is controlled by many genes. The plumule and radicle length characters decrease positively and very strongly with the character of the water content of the sprouts. While the dry weight of the sprouts has a negative and very significant effect on the water content of the sprouts, the dry weight character of the sprouts produces the highest direct effect, and the radicle length character produces the highest indirect effect. Thus, the characters of the water content of the sprouts and the length of the plumule can be used as selection characters for rice seed germination tests using seed soaking treatments.
