One of the obstacles in shallot cultivation is the attack of purple spot disease caused by the fungus Alternaria porri. Alternative disease control that can be done and is relatively safe for the environment is biological control using indigenous endophytic fungi isolated from the plant to control the disease. Biological control using indigenous microorganisms will be more successful because of their higher compatibility and adaptability. This study aimed to characterize and determine the ability of 5 isolates of endophytic fungi islated fron shallot to control the pathogenic fungus Alternaria porri in vitro. It was carried out through observation and experiment, consisting of: (1) isolation and characterization of endophytic fungi on shallots and (2) in vitro testing of endophytic fungi against A. porri. The data obtained from observations were analyzed descriptively and the data from the inhibitory test were analyzed by analysis of variance, to test five endophytic isolates obtained from shallot root and leaf tissues. The results of this study indicated that: (1) isolate B belonged to the genus Nigrospora, isolate C to the genus Aspergillus, isolate D to the the genus Epicoccum, whereas isolates A and E were unknown; (2) 5 isolates of this indigenous endophytic fungus were hypovirulent with a disease severity index <2 so that they could be used as disease control agents; (3) 5 isolates of indigenous endophytic fungi of shallots showed inhibition ranging from 47.76%-55.25%, with isolate C genus Aspergillus having the highest inhibition with a percentage of 55.25%.

Papaya (Carica papaya L.) cultivation gets a lot of disturbances such as pests or diseases that can reduce the quality and quantity of papaya fruit. The use of vegetable insecticides is effective in controlling pests and has potential as a plant insecticide such as citronella, neem and cloves. This study aims to determine daily mortality and obtain the most effective botanical insecticides in controlling mealybug pests on papaya plants. The study consisted of two stages: (1) assessing the percentage of daily mortality, (2) the effectiveness of citronella oil, neem extract and clove oil vegetable insecticides on papaya seedlings. Daily mortality data were calculated using the daily mortality formula and data on the effectiveness of vegetable insecticides were analyzed using analysis of variance. The results showed that the highest percentage of mortality by giving citronella oil had a 24-hour daily mortality percentage and clove oil at a 48-hour daily mortality percentage. Botanical insecticides had an effect on all observation parameters, plant height, number of leaves and stem diameter, while the most effective treatment in controlling the mealybug P. marginatus treatment N1 was citronella oil with a concentration of 1 cc/500 mL.

Buah pepaya sangat disukai oleh masyarakat Indonesia karena rasanya yang manis dan memiliki kandungan nutrisinya yang tinggi. Salah satu organisme penganggu tanaman yang menyebabkan kehilangan hasil buah pepaya adalah penyakit antraknosa yang disebabkan oleh jamur Colletotrichum spp., yang merupakan penyakit penting bagi tanaman pepaya. Penelitian ini bertujuan untuk memberikan informasi mengenai penyakit antraknosa pepaya di Kelurahan Rantau Panjang, Kecamatan Rumbai Barat. Pengamatan kondisi lahan dengan sistem tumpang sari dan tunggal, gejala penyakit antraknosa, serta dilakukan pengukuran tingkat insidensi dan keparahan penyakit di lapangan. Hasil pengamatan penyebab busuk buah pada pepaya adalah jamur C. gloeosporioides. Persentase insidensi penyakit busuk buah sistem tanam tumpang sari paling tinggi mencapai 25%, sedangkan sistem tanam tunggal 10%. Keparahan penyakit busuk buah akibat C. gloeosporioides pada sistem tanam tumpang sari berkisar 8-10% sedangkan pada sistem tanam tunggal berkisar 5-6%. Tingginya tingkat serangan insidensi dan keparahan penyakit pada sistem tanam tumpang sari disebabkan tidak adanya sanitasi lahan terhadap buah yang terinfeksi dan kesalahan dalam pemilihan tanaman tumpang sari seperti cabai dan keladi selain itu penggunaan pestisida yang tidak tepat sasaran diduga menyebabkan penyakit ini selalu ada di lahan.

This study aims to implement an expert system using a web-based backward chaining method approach to help farmers diagnose and manage tomato plant diseases. This study was conducted because diagnosing plant diseases requires the help of agricultural experts, which causes problems with consultation costs and farmers who have difficulty knowing the type of disease in tomato plants will cause losses for farmers due to crop failure. The methodology used in this study is the prototype method which begins with identifying problems through data collection from literature, interviews with agricultural experts, and field observations. The collected data is then analyzed using the backward chaining method to trace symptoms to the cause of the problem and provide recommendations for handling. This system is implemented in the form of a web application that facilitates access for farmers. The results of the study show that this expert system is able to provide accurate and reliable diagnoses and recommendations with an accuracy level of this study of 85%. Thus, this expert system is expected to improve farmers' knowledge and skills in managing tomato plants, as well as contribute to increasing yields and the quality of agricultural products

Ketergantungan petani akan penggunaan pupuk Urea pada tanaman padi sawah perlu dicarikan alternatif lain, umumnya petani memberikan pupuk terutama urea dengan takaran yang cukup tinggi, mencapai 300 kg/ha, bahkan hasil survei menyatakan bahwa 400 kg/ha diberikan pemerintah sebagai dukungan terhadap produksi padi, hanya saja bantuan tersebut bagi petani padi sawah dianggap terlalu kecil dan masih kurang. Solusi pemecahan masalahnya dengan meningkatkan pengetahuan dan pemahaman serta ketrampilan mitra tentang pengembangan azolla dalam budidaya padi sawah. Metode kegiatan antara lain FGD (Focus Group Discussion), praktek budidaya azolla, pendampingan, dan evaluasi. Berdasarkan hasil kegiatan pengabdian kepada masyarakat yang telah dilakukan tim dapat disimpulkan peserta dalam mengikuti kegiatan FGD sangat aktif selama kegiatan berlangsung, dimana peserta menunjukkan semangat dan antusias yang baik pada saat diskusi mengenai materi yang diberikan terkait budidaya azolla ditunjukkan dengan banyaknya pertanyaan yang diajukan mitra dalam diskusi, berdasarkan jawaban spontan dari beberapa petani terlihat bahwa seluruh yang hadir belum mengenal azolla. Beberapa petani mengemukakan baru mendengar saat diperkenalkan nama azolla, dan terasa asing bagi kelompok tani. Setelah kegiatan para mitra telah mempunyai pengetahuan dan pemahaman yang sangat memuaskan untuk melakukan kegiatan budidaya azolla secara mandiri.

Fish wealth in the Indonesian region is abundant and efforts are continuously being made to increase the catch. Abundant fish catches become leftover fish or discarded fish due to various reasons, for example the fishermen's limited knowledge and facilities in fish processing methods. It turns out that the remaining fish or discarded fish can still be used. Nowadays snakehead fish (Channa striata) is widely used to make fish sauce, but in the manufacturing process only the flesh is used, this causes the skin and bones to become unusable waste. In general, fish waste contains many nutrients, namely N (Nitrogen), P (Phosphorus) and K (Potassium), which are components of organic fertilizer.The increase in waste production greatly influences global warming which triggers climate change. With proper processing in accordance with the environment and its presence in the environment, it is hoped that the environment will be clean, healthy and comfortable, in addition, appropriate waste can produce use value that will add income. From the research results, it can be concluded that the addition of the bromelain enzyme with a concentration of 150 mL produces the highest nitrogen content, namely 0.39%, while for the phosphorus content, the addition of 150 mL of enzyme shows a higher value, namely 0.168% and the highest nitrogen content, namely 0.037%, is owned by POC with the addition of 150 mL of bromelain enzyme.
