Abstract

Tropical regions face threats from pests, leading to significant losses in the global potato supply. Intercropping potatoes with faba beans is being explored to control pest infestations in tropical areas. This study aims to provide insights into pest dynamics and improve pestmanagement strategies for sustainable potato cultivation. The research evaluates five cropping systems, each replicated across seven beds: potato monoculture, alternating growth of potatoes and faba beans at a 2:1 ratio, planting faba beans between the rows of potatoes at a 1:1 ratio, growing faba beans between two beds of potatoes, and cultivating solely faba beans. The study looked at various factors such as the type and intensity of pest attacks on potatoes. It found that planting faba beans alongside potatoes can help reduce aphid (Homoptera: Aphididae) and mirid bug (Hemipetra: Miridae) attacks, but may not affect grasshopper (Orthoptera: Acrididaeand Pyrgomorphidae) attacks. The distance between potato beds and the population of faba bean plants can also influence pest interactions. Understanding these dynamics offers important information for sustainable pest management practices in intercropping systems.

Abstract

Penurunan kandungan karbon organik dalam tanah sering kali menjadi dampak dari penerapan praktik budidaya yang kurang ramah lingkungan di agroekosistem salah satunya adalah lahan perkebunan. Penelitian ini bertujuan untuk mengidentifikasi praktik budidaya yang diterapkan di berbagai perkebunan di Sub DAS Tuntang, mengetahui kandungan karbon organik tanah, serta menganalisis hubungan antara praktik budidaya dengan kandungan karbon organik tanah. Penelitian dilakukan melalui survei lapangan di 41 titik sampel menggunakan metode stratified random sampling, disertai observasi agroekosistem dan wawancara petani. Analisis hubungan antara praktik budidaya dengan kandungan SOC dilakukan menggunakan Fisher's Exact Test. Hasil menunjukkan bahwa sebagian besar praktik budidaya seperti pemupukan, pola tanam, pengolahan tanah, penutup tanah, dan pengendalian hama tidak memiliki hubungan signifikan dengan kandungan karbon organik tanah. Namun, pengelolaan sisa tanaman dengan membiarkannya terurai secara alami terbukti memiliki hubungan signifikan dalam meningkatkan kandungan karbon organik tanah. Temuan ini menunjukkan bahwa retensi residu tanaman merupakan strategi yang efektif untuk memperbaiki kualitas tanah sekaligus mendukung upaya mitigasi perubahan iklim di lahan perkebunan.

Abstract

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.

Abstract

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.

Abstract

Peningkatan jumlah penduduk di wilayah perkotaan meningkatkan permintaan untuk pasokan makanan bergizi secara berkelanjutan. Penelitian oleh Pinto et al. (2015) menunjukkan bahwa microgreens selada, meskipun memiliki kandungan nitrat lebih rendah dibandingkan tanaman dewasa, mengandung mineral seperti kalsium, magnesium, besi, mangan, seng, selenium, dan molibdenum dalam kadar yang lebih tinggi. Dengan meningkatnya limbah cangkang telur puyuh akibat konsumsi telur puyuh yang meningkat 16,4% di Indonesia (Susenas, 2016), perlu dilakukan daur ulang limbah tersebut. Penelitian ini bertujuan untuk menilai pengaruh penambahan cangkang telur puyuh terhadap pertumbuhan dan hasil microgreens selada serta menentukan dosis terbaik untuk hasil optimal. Menggunakan metode Rancangan Acak Kelompok (RAK), penelitian ini melibatkan lima perlakuan (kontrol dan dosis cangkang telur puyuh 10g, 20g, 30g, 40g) yang diulang lima kali, dengan 25 sampel. Parameter yang diamati termasuk tinggi tanaman, klorofil, karotenoid, dan vitamin C. Hasilnya menunjukkan bahwa penambahan cangkang telur puyuh mempengaruhi tinggi tanaman, klorofil, dan karotenoid. Perlakuan kontrol menghasilkan tinggi tanaman terbaik (6,998 cm), sedangkan penambahan 40 gram cangkang telur puyuh memberikan hasil terbaik untuk klorofil dan karotenoid dengan nilai 3,341; 1,169; dan 0,997.

Abstract

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.

Abstract

Whiteflies (Bemisia tabaci) are a major pest of curly red chili peppers, acting as vectors for gemini viruses that significantly reduce crop productivity. This study evaluated the efficacy of neem and basil leaf extracts at three different concentrations for controlling whitefly infestations on chili plants. A randomized complete block design (RCBD) was employed with 8 treatments and 2 controls: PA (Neem 1%), PB (Neem 2%), PC (Neem 3%), PD (Basil 1%), PE (Basil 2%), PF (Basil 3%), PKM (commercial pesticide as positive control), and P0 (distilled water as negative control). Parameters assessed included whitefly infestation intensity, yellowing of shoots, fruit weight, total fruit count, and the number of infested fruits. The results indicate that both neem and basil leaf extracts effectively reduced whitefly infestation intensity and yellowing of shoots compared to the negative control (P0). Despite some increase in infestation intensity in subsequent observations, both neem and basil extracts positively impacted fruit yield, including higher fruit weight and total fruit count. However, there was no significant effect on the number of infested fruits with the treatments. These findings suggest that neem and basil leaf extracts are promising alternatives for managing whitefly infestations and improving yield in curly red chili peppers.
