The invasion of the ladybug (Vatiga illudens) has started a new chapter in Indonesia, with the first report of this pest in East Java Province in 2021. As a pest that attacks cassava plants, this pest is a threat to cassava plantations, one of which is in Banyumas District, Central Java Province. It is necessary to identify potential natural enemies that can become biological agents that suppress pest populations in the field and insects associated with cassava cultivations to control the pest and anticipate losses due to decreased production of cassava plants in the Banyumas District. This study aimed to explore and describe the natural enemies of ladybug pests and insects associated with cassava cultivations in the Banyumas District. The research was conducted in September 2022-January 2023 in seven cassava cultivation locations in Banyumas District. Samples of pests and or natural enemies were collected using a purposive random sampling method. The results showed a community of potential natural enemies of V. illudens and insects associated with cassava cultivations from the Orders Hemiptera, Diptera, Orthoptera, Coleoptera, and Araneae. The Results showed that 15 species act as potential natural enemies, eight species as pests, and two species as none of them (neutral).

Kepik Vatiga illudens (Drake, 1992) (Hemiptera: Tingidae) merupakan hama baru yang masuk Indoensia. Masuknya V. illudens ini menimbulkan kekhawatiran tentang invasi dan potensinya sebagai hama singkong eksotik baru di Indonesia. Minimnya informasi dasar tentang V. illudens, akan mempersulit penilaian dan prediksi wabah hama di Indonesia. Kabupaten Banyumas wajib mengantisipasi serangan hama tersebut karena memiliki kawasan tanam singkong yang cukup luas pada tahun 2018 yaitu 1.711 ha dengan hasil panen yang juga termasuk banyak dibanding tanaman pangan lainnya. Penelitian ini bertujuan untuk mengetahui tingkat (intensitas) serangan hama baru tersebut pada salah satu aksesi singkong yang ada di Kabupaten Banyumas, khususnya Kecamatan Sumbang, di lingkungan screenhouse Fakultas Pertanian Universitas Jenderal Soedirman. Penelitian menggunakan ulangan sebanyak 3 (tiga) kali, dengan satu set tanaman sebagai control. Pengamatan dilakukan selama 30 (tiga puluh hari). Hasil penelitian menunjukkan bahwa intensitas serangan mengalami kenaikan dari hari ke-hari. Meskipun cenderung mengalami peningkatan, mulai hari ke-18, serangan menunjukkan skala yang stasioner (tetap) hingga hari ke-30.

Spiders are the main natural enemies (predators) for pests that attack crops. Knowledge about the relationship between Arthropods found on agricultural land and the bacteria carrying these animals, which are symbiotic, still needs to be found in Indonesia. Spiders are important biocontrol agents in agricultural land. This study examined the relationship between bacteria potentially carried by spiders, as members of the Phylum Arthropoda, in chili plants grown in agroecosystems. This study aimed to determine the presence of bacteria carried by spiders in chili planting areas of the Banyumas Regency. This study found a species of spider (Oxyopes lineatipes) collected from chili crops in 3 (three) sub-districts in Banyumas Regency. From these spiders, 5 (five) bacteria isolates were found, both from inside the body and from the surface of the spider's body. The results of the hypersensitivity test showed that 2 (two) isolates were non-pathogenic bacteria, while the other 3 (three) isolates had potential as plant pathogens. However, further research is still being carried out regarding identifying the bacterial species found.

Singkong merupakan tanaman yang dapat hidup sepanjang tahun dan berasal dari Amerika Selatan dengan lembah sungai Amazon sebagai tempat penyebarannya. Indonesia menduduki lima besar negara pengekspor singkong dunia. Namun demikian, di Kabupaten Banyumas, Provinsi Jawa Tengah, data luas panen tanaman ini mengalami fluktuasi. Salah satu hal yang dapat mempengaruhi fluktuasi produksi singkong di Kabupaten Banyumas adalah munculnya potensi serangan hama baru, Vatiga illudens. Penelitian ini bertujuan untuk mengetahui potensi intensitas serangan hama Vatiga illudens secara ex situ terhadap 7 (tujuh) aksesi tanaman singkong yang dikoleksi dari seluruh wilayah di Kabupaten Banyumas. Sebanyak 7 (tujuh) aksesi tanaman singkong yang digunakan dikoleksi dari Kecamatan Sokaraja, Sumbang, Ajibarang, Gumelar, dan Cilongok. Penelitian dilakukan di Screen House Fakultas Pertanian, Universitas Jenderal Soedirman. Hasil penelitian menunjukkan bahwa berdasarkan uji lanjut Beda Nyata Terkecil (BNT) pada taraf α 5% yang telah dilakukan, aksesi tanaman singkong yang dikoleksi dari Kecamatan Gumelar menunjukkan rata-rata intensitas serangan tertinggi (22,34%) dibandingkan dengan yang lain. Intensitas serangan terendah (2,69%) ditunjukkan oleh aksesi tanaman singkong dari Kecamatan Cilongok. Penelitian ini dapat dijadikan sebagai dasar dalam menentukan metode pengendalian hama terpadu yang spesifik sesuai dengan karakter tanaman budidaya dan hama yang menyerang tanaman tersebut.

The growth and yield of plants are strongly influenced by the early growth ability of the plants. Similar germination and good seed vigor will greatly support plant growth and increase production. Increasing the germination and vigor of seeds can be done through biopriming. The application of biopriming using rhizobacteria is developing environmentally friendly agricultural technology. This study aimed to determine the effect of inoculation of rhizobacteria from the north coast of Pemalang on rice plants' germination and vigor index. The study was arranged in a Randomized Block Design, consisting of 10 treatments with three replications. Ten rhizobacteria isolates were isolated from the North Coast of Pemalang, Central Java, consisting of Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn, and K3. The biopriming with rhizobacteria isolated from the rice rhizosphere of the Northern Coast of Pemalang increased the seed germination rate, seed vigor index, and early vegetative growth of rice seedlings. Inoculation with isolate J12 produced the highest vigor index of 8280.01. The results of this study imply that the application of rhizobacteria from saline soil has the potential to increase the vigor of rice seedlings to impact better seedling growth in saline conditions.

Padi merupakan komoditas pangan yang memiliki peranan terpenting dalam memenuhi kebutuhan pokok masyarakat Indonesia. Ekstensifikasi produksi padi dapat dilakukan dengan memanfaatkan lahan marjinal seperti lahan salin. Lahan salin merupakan lahan yang memiliki kadar kadar garam tinggi akibat intrusi air laut maupun tingginya laju evaporasi. Pengembangan budidaya padi di lahan salin memiliki kendala berupa serangan patogen busuk pelepah (Rhizoctonia solani). Alternatif pengendalian patogen selain menggunakan pestsida kimia, dapat dilakukan menggunakan Plant Growth Promoting Rhizobacteria (PGPR), seperti kelompok bakteri diazotrof. Penelitian ini bertujuan untuk mengetahui potensi bakteri diazotrof lahan salin dalam meningkatkan ketahanan tanaman padi serta kemampuannya dalam memacu pertumbuhan padi yang terinfeksi R. solani. Penelitian dilaksanakan di Experimental Farm dan Laboratorium Agronomi & Hortikultura, Fakultas Pertanian Unsoed pada bulan Oktober 2021 - Februari 2022. Rancangan yang digunakan adalah Rancangan Acak Kelompok Lengkap (RAKL) dengan 11 perlakuan dan diulang tiga kali, meliputi kontrol tanpa inokulasi bakteri diazotrof dan inokulasi isolat Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn dan K3. Semua tanaman juga dinokulasi dengan Rhizoctonia solani. Hasil penelitian menunjukkan bahwa inokulasi bakteri diazotrof dapat meningkatkan ketahanan padi yang terinfeksi jamur R. solani, ditandai dengan penurunan intensitas penyakit hingga 70%, peningkatan kandungan saponin, tanin dan hidrokuinon, serta peningkatkan pertumbuhan tinggi tanaman dan panjang akar total padi.ABSTRACTRice is the most important food commodity that supply the basic needs of the Indonesian people. The development of rice cultivation in salin land has obstacles in the form of attacks by sheat blight pathogen (Rhizoctonia solani). Alternative to controlling pathogens other than using chemical pesticides is by using Plant Growth Promoting Rhizobacteria (PGPR), such as diazotroph bacteria. This research aimed to determine the potential of diazotrof bacteria in increasing rice resistance and its ability to stimulate the growth of rice infected with R. solani. The research was carried out at Experimental Farm and Agrohorti Laboratory, Faculty of Agriculture Unsoed in October 2021 - February 2022. The design used was Randomized Completely Block Design (RCBD) with 11 treatments and repeated three times, including controls without inoculation of diazotroph bacteria and inoculation of isolates Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn and K3. All plants were also inoculated with R. solani. The results showed that inoculation with diazotrof bacteria could increase the rice resistance towards attack of sheath blight pathogen (R. solani) that characterized by a decrease disease intensity up to 70%, increase saponins, tannins and hydroquinones content, also increase growth of plant height and total root length of rice.

High-yielding varieties are the primary determinant of the success of increasing Indonesia's rice production. Plant breeding for new high-yielding varieties is possible through mutation induction and selecting desired traits. The effectiveness and efficiency of selection require comprehensive genetic parameters. This study aimed to study the genetic diversity, heritability, genetic advance, and relationship between yield components and yield in the M1 generation of mutant rice irradiated with gamma ray. This research used a factorial randomized complete block design, involving gamma irradiation doses of 100 Gy, 150 Gy, and 200 Gy, as the first factor; and the second factor was the rice genotype: UnsoedBDBP, UnsoedBDIU, UnsoedBPIU, UnsoedIUBD, and UnsoedIBP. Each treatment was repeated three times. Results showed that traits with broad genetic variation were tiller number plant-1, grain number panicle-1, and grain yield plant-1. High heritability and genetic advance values were found in plant height, grain number panicle-1, and yield plant-1, indicating that improvement in these traits can be achieved simply through selection methods. Panicle number plant-1 and filled grain percentage panicle-1 showed a unidirectional relationship and directly affected high values on yield plant-1. Therefore, these traits can be considered selection indicators for breeding high-yielding mutant rice.
