Abstract

Kerusakan benih selama penyimpanan dapat disebabkan oleh infeksi patogen tular benih. Akibatnya dapat terjadi penurunan daya kecambah maupun kematian bibit. Suhu dan kelembaban merupakan salah satu faktor penyebab kemunduran fisiologi benih selama penyimpanan. Oleh karena itu, penelitian ini bertujuan untuk menguji pengaruh suhu dan kelembaban selama penyimpanan terhadap daya kecambah dan cendawan patogen yang berasosiasi dengan benih kedelai. Rancangan yang digunakan pada penelitian ini adalah Ranncangan Acak Lengkap yang terdiri dari 3 perlakuan, yaitu suhu dan kelembaban ruang (kontrol), suhu rendah, dan kelembaban rendah. Setiap perlakuan diulang sebanyak 5 kali.  Benih kedelai disiapkan dengan membungkus 10 butir benih dengan kain kasa sejumlah perlakuan dan ulangan. Benih yang telah dibungkus kasa kemudian disimpan pada suhu dan kelembaban ruang, pada suhu dingin 4oC di refrigerator dan kelembaban rendah (30%) pada desikator yang ditambah silica gel. Setelah 3 minggu penyimpanan, benih kedelai ditumbuhkan dengan metode blotter test. Pada 7 hari setelah tanam, benih yang berkecambah dihitung daya kecambah dan daya infeksi cendawan patogen. Data yang diperoleh kemudian dianalisis ragam dan dilanjutkan dengan uji Tukey sebagai pada taraf5%.Hasil penelitian menunjukkan bahwa perlakuan suhu dan kelembaban dapat menjaga mutu benih dengan daya kecambah 96.67-100%. Perlakuan suhu dingin dan kelembaban rendah juga dapat menghindarkan benih kedelai dari infeksi Cladosporium sp. dan Rhizopus sp.

Abstract

Colletotrichum gloesporiodes is one of the species of Colletotrichum that causes anthracnose on various fruits both in the field and postharvest. C. gloesporiodes is a cosmopolitan pathogen so it is important to know which fruits can be infected as a basis for prevention. This study aimed to determine the host range and virulence level of C. gloesporiodes in several postharvest fruits. The research was conducted at the Agrotechnology Intermediate Laboratory, Gunadarma University from March 2022 to April 2022. This study used a completely randomized design consisting of 4 types of fruit (mango, chili, papaya, and tomato) as treatment. Each treatment consisted of 4 units and then repeated 3 times so that there were a total of 48 experimental units. C. gloesporiodes isolate was obtained from mango fruit with anthracnose symptoms. The isolates obtained were inoculated to tomatoes, chilies, papayas, and mangoes as controls. Anthracnose symptoms and lesin diameter were observed at 7 days after inoculation. The diameter of the lesin was measured to determine the level of virulence. The results showed that C. gloesporiodes was able to colonize and infect chilies, papayas, and mangoes as hosts, but there was no inoculated to tomatoes. The ability to colonize and infect is indicated by symptoms in the form of yellow to black spots, sunken, and watery. The virulence category showed different levels in each fruit with a range from very low to moderate. The conclusions obtained from this study were that C. gloesporiodes was able to infect chilies and papayas with different levels of virulence.

Abstract

Vetiver (Vetiveria zizanioides L.) is a plant that produces essential oils. The use of mycorrhiza and P fertilizer on vetiver plants can support growth and increase root crop production. However, the exact dose of P fertilizer is not yet known to increase and support the growth and production of vetiver plants. For this reason, the dose of fertilization treatment was carried out to see which doses could be associated with Arbuscular Mycorrhizal Fungi (AMF) which could help the growth of vetiver plants. This study used a factorial Randomized Block Design (RAK) with two factors. The first factor was AMF inoculation consisting of 2 levels, without AMF inoculum (M0) and inoculum administration (M1). The second factor is the dose of Phosphor (P) fertilizer consisting of 3 levels, namely, the dose of 50% P fertilizer as much as 397 mg/polybag (P1), 100% P fertilizer at 793 mg/polybag (P2) and 150% P fertilizer as much as 1,190 mg/polybag (P3 ). The results showed that the AMF inoculum had not been able to increase the growth and yield of vetiver plants. AMF inoculum affects the number of spores and root infections. P fertilizer has not been able to increase the growth and production of vetiver plants. There was no interaction between the two treatments.

Abstract

Rosella is a shrub that has potential as an industrial and pharmaceutical raw material. Rosella production in Indonesia remains relatively low, at only 2-3 tons per hectare, while plant quality is declining due to continuous inorganic fertilization. This study aims to determine the effect of providing photosynthetic bacteria (BPS) and compound NPK fertilizer. This research was conducted for 6 months from January to June 2025 in the rosella land of Gunadarma University Technopark Cianjur using a 2-factorial Randomized Completely Block Design (RCBD). The first factor is photosynthetic bacteria with 4 levels, namely without PSB/Control (P0), PSB 5 ml/L (P1), PSB 10 ml/L (P2), PSB 15 ml/L (P3) and the second factor is compound NPK, namely NPK 11,5 g/plant (N1), NPK 17 g/plant (N2), NPK 22,5 g/plant (N3). There were 12 treatment combinations which were repeated 3 times and there were 4 samples so there were 144 experimental units. The parameters observed include growth and production results. Growth parameters include plant height, number of primary branches, and number of productive branches, while yield parameters include fresh fruit weight per plant, fresh fruit calyx weight per plant, dry fruit weight per plant, and dry fruit calyx weight per plant. The data obtained were analyzed using ANOVA at 5% level and further tested using the DMRT test. The results of the study showed that photosynthetic bacteria had a significant effect on plant height, number of productive branches, and dry weight of fruit per plant, while compound NPK fertilizer only had a significant effect on plant height. The results showed no interaction between photosynthetic bacteria and compound NPK on all parameters. Keywords: Photosynthetic bacteria, compound NPK, functional microbes, rosella

Abstract

Tanaman kacang panjang polong ungu memerlukan ketersediaan hara serta kondisi lingkungan yang mendukung agar mampu mencapai pertumbuhan dan hasil optimum. Salah satu pendekatan pemupukan yang lebih ramah lingkungan adalah penggunaan pupuk hayati, seperti pupuk hayati yang digunakan pada penelitian ini mengandung mikroorganisme Pantoea dispersa, Azospirillum sp., Aspergillus niger, Streptomyces sp., dan Penicillium oxalicum, yang berperan dalam penambatan nitrogen, pelrutan fosfat, serta dekomposisi bahan organik. Mikroba tersebut berfungsi memperbaiki struktur tanah, meningkatkan ketersediaan nutrisi.Tujuan penelitian ini adalah untuk mengidentifikasi respons pertumbuhan dan produktivitas kacang panjang polong ungu terhadap pemberian pupuk hayati. Kegiatan penelitian berlangsung pada Maret hingga Juni 2025 di Kebun Percobaan Kampus F7 Universitas Gunadarma, Jakarta Timur. Rancangan percobaan yang diterapkan ialah rancangan kelompok lengkap teracak (RKLT) nonfaktorial dengan lima taraf dosis pupuk hayati, yaitu 0, 5, 6,5, 8, 9,5 g/polybag. Dalam penelitian ini digunakan 8 ulangan. Setiap perlakuan terdiri atas 2 sampel pada setiap ulangan, sehingga diperoleh 40 satuan percobaan dengan total 80 unit percobaan. Hasil penelitian menunjukkan bahwa pemberian pupuk hayati berpengaruh nyata terhadap jumlah polong, bobot 100 biji, dan bobot polong kering. Perlakuan 9,5 g/polybag menghasilkan yang terbaik, sehingga menghasilkan nilai tertinggi pada ketiga parameter tersebut sehingga dapat dianggap sebagai dosis paling efektif dalam meningkatkan hasil kacang panjang polong ungu.
