Desa Cukilan di Kabupaten Semarang Provinsi Jawa Tengah memiliki potensi talas kimpul (Xanthosoma sagittifolium) menjadi komoditas andalan desa. Ada 11 warga desa Cukilan yang berkomitmen membentuk kelompok usaha terpadu untuk mengolah kimpul menjadi produk bernilai jual tinggi, melakukan pemasaran, dan mengembangkan kebun kimpul sebagai penyedia bahan baku. Cita-cita mereka terkendala minimnya ilmu pengetahuan, teknologi, dan ketrampilan. Melalui kegiatan pengabdian masyarakat ini, pengusul dan mitra calon usahawan hendak: 1) Meningkatkan penerapan ipteks oleh mitra untuk menciptakan variasi olahan kimpul serta memasarkannya secara luas, 2) Meningkatkan penerapan ipteks dan wawasan lingkungan oleh petani dalam mengelola kebun kimpul, dan 3) Menerapkan manajemen usaha hulu-hilir kimpul yang terpadu dan kolaboratif antar anggota usaha pengolahan kimpul, anggota pemasaran, dan petani. Terdapat tiga fokus kegiatan yaitu: a) Pelatihan dan pendampingan anggota untuk menciptakan dan memasarkan tepung dan snack kimpul yang berkualitas, higienis, dan menarik, b) Pelatihan dan pendampingan petani untuk meningkatkan produktivitas dan keberlanjutan kebun kimpul, dan c) Pendampingan manajemen usaha terpadu. Selama kegiatan pelatihan dan pendampingan berlangsung, telah dihasilkan produk berupa tepung kimpul Cukilandz dan beberapa olahannya, pembibitan kimpul, akun pemasaran online, keikutsertaan dalam ekspo/pameran pangan maupun pertanian, penjualan tepung kimpul, serta sinergi antara pengusaha olahan, pemasar, dan petani. Kemampuan dan ketrampilan mitra pun bertambah baik dari aspek pengolahan hasil kimpul, pemasaran, maupun pengelolaan kebun.

The excessive use of synthetic chemical pesticides in controlling plant diseases poses significant challenges to sustainable agriculture. As an environmentally friendly alternative, plant growth-promoting rhizobacteria (PGPR) have shown promise by colonizing plant roots and forming symbiotic relationships that enhance plant growth and suppress plant pathogens. Research on the isolation of PGPR from ginger (Zingiber officinale) rhizosphere in Indonesia remains limited, highlighting the need for further exploration to support genetic resource conservation and sustainable agricultural practices. This study aims to evaluate the potential of PGPR isolates from Z. officinale rhizosphere in Semarang, Indonesia, as biological control agents. Isolates were characterized based on morphology, biochemical traits, and their antagonistic activity against fungal pathogens, including Fusarium oxysporum, Colletotrichum sp., and Alternaria sp. A total of 14 isolates were obtained, exhibiting diverse morphological, biochemical, and antagonistic properties. Among them, isolate 235A2 demonstrated the highest potential as a biological control agent, with capabilities including phosphate solubilization, nitrogen fixation, protease enzyme production, and significant inhibition rates of F. oxysporum (13.79%), Colletotrichum sp. (55.56%), and Alternaria sp. (35.61%) in vitro. These findings underscore the potential of PGPR as a sustainable alternative for biological control of plant pathogens, supporting both enhanced plant productivity and environmental conservation.

The use of synthetic pesticides is not effective in reducing the prevalence of disease because it produces residues and does not support biodiversity. This is an unwise practice and can cause problems in the future. The use of endophytic microorganisms is widely used to control plant diseases and pests, because it is known to have various pathogen inhibition mechanisms. Biological agents that are used to inhibit plant pathogens and have been widely developed, one of which is endophytic bacteria. The purpose of the research was to evaluate the potential of endophytic bacterial isolate from ginger plants as biological control agents. The type of research used is descriptive and exploratory. Sampling of healthy ginger plants was carried out at 5 points in two sub-districts, namely Getasan and Sumowono, Semarang Regency. Isolation is carried out by taking healthy ginger plants from the roots, rhizomes, fronds, and leaves. Characterization and selection of isolates were carried out by testing their phosphate dissolving ability, nitrogen anchoring, amylase and protease activities, and antagonist tests with Fusarium oxysporum in vitro. The results of this study are that (1) 20 pure isolates were successfully isolated consisting of 2 isolates derived from leaves, 4 isolates from fronds, 8 isolates from roots, and 6 isolates from rhizomes; (2) D91 isolate has the potential as a biological agent with an antagonist mechanism of 86.91% supported by protease enzyme activity, able to dissolve phosphate and anchor nitrogen.

The Ralstonia solanacearum species complex is a highly destructive plant pathogen with a remarkably broad range of hosts, and ongoing discoveries continue to expand its host list. In May 2023, a new type of bacterial wilt affecting ginger (Z. officinale) crops in Semarang Regency, Central Java was reported. Early symptoms included sudden withering of leaves in adult plants followed by complete wilting and darkening of the vasculature, ultimately leading to plant death. This research specifically investigates the spread of Ralstonia solanacearum Species Complex within ginger cultivation in Semarang Regency. Twenty bacterial isolates were collected from soil and diseased Z. officinale plants at twenty different locations. Physiological and biochemical analyses confirmed that the causative agent for Z. officinale bacterial wilt was Ralstonia solanacearum belonging to biovar 3 and 4. The study also revealed that the distribution of this pathogen remains focused in the Banyubiru and Sumowono sub-districts. These findings will enhance our understanding of how Ralstonia solanacearum Species Complex spreads among ginger crops and its impact on them.

The Ralstonia solanacearum Species Complex (RSSC) is a significant plant pathogen affecting various agricultural commodities, including ginger. Understanding the distribution and characteristics of RSSC in ginger plants is crucial for effective disease management. This study aims to determine the distribution of RSSC in ginger plants and identify the pathogen through morphological and biochemical characterization. The research was conducted in Banyubiru and Getasan districts, Semarang Regency, Indonesia. The study involved purposive sampling, isolation, and purification of isolates, followed by morphological characterization through observation and biochemical characterization using Gram staining with KOH, oxidase test, arginine activity test, hypersensitivity test, bacterial density calculation, Koch's postulates, and biovar characterization. Three isolates from Banyubiru displayed typical morphological characteristics of RSSC, including round, mucoid colonies with red centers and white edges on TZC medium, and rod-shaped bacterial cells. Biochemical characterization identified these isolates as RSSC strains biovar 3 and 4, capable of causing bacterial wilt in ginger plants. The study confirmed the presence of bacterial wilt in ginger in Banyubiru district. The findings reveal the spread of bacterial wilt caused by RSSC in ginger plants in Banyubiru, Semarang Regency. There is a need for measures to control the potential spread of RSSC in the surrounding host plant areas in Tlumpak Village, Banyubiru district.

Penelitian ini dilakukan untuk mengidentifikasi dan mengelompokkan jenis serangga yang terdapat pada tiga genotip sorgum lokal Sumba Timur, yaitu WH Mitting Nggangga, WH Rara Kadita, dan WH Mitting Tadda. Penelitian dilaksanakan di lahan Sains Technopark, Universitas Kristen Satya Wacana, pada Juni hingga November 2024. Metode yang digunakan bersifat eksploratif dengan pemasangan perangkap yellow trap secara sistematis untuk mengamati populasi dan peran serangga. Hasil penelitian menunjukkan bahwa ordo Hemiptera dan Diptera paling dominan, dengan genus Bemisia sp. dan Musca sp. sebagai hama utama. Jumlah serangga tertinggi ditemukan pada genotip WH Mitting Tadda (1257 individu), dan terendah pada WH Mitting Nggangga (1096 individu). Indeks keanekaragaman (H’) berada pada kategori sedang, yaitu antara 1,52–1,67, dan indeks dominansi tergolong sedang, antara 0,26–0,30. Serangga predator dan penyerbuk ditemukan dalam jumlah lebih sedikit dibandingkan hama. Hasil ini menunjukkan bahwa keseimbangan ekosistem di lahan budidaya masih cukup stabil, namun memerlukan perhatian terhadap pengelolaan hama dan konservasi musuh alami agar produktivitas sorgum tetap optimal.
