Abstract

Endophytic fungi in lately was getting a lot of attention in agriculture. Besides being able to increase plant resistance against plant pest organism, it has also the ability to stimulate germination and pant growth. One of endophytic fungi tested in its research was Beauveria bassiana from isolate Wheat, Coffeae, Cacao and entomopatogen fungus from Leptocorisa acuta insect. The aim of this research was to know the ability of Beauveria bassiana from some tested isolates and its effect on chlorophyll content of leaf chili followed Mack Kinner methode by doing seed treatment aplication. Colonization and chlorophyl content of chili leaf was done on 7 MPI. The research design used Random Block Design non factorial, data was analysis by 8 STAT. The result showed all of Beauveria bassiana isolates were able to colonize and established as endophytic in chili plant.Beauveria bassiana of wheat isolate was the best isolate giving spurring germination and seedling plant growth and not significant with B.bassiana isolate from Leptocorisa acuta insect. Aplication of B.bassiana isolates was able to increase the chlorophyll contentof chilileaf compared control. All of the tested B.bassiana fungus could increased chlorophyl-b content and chlorophyl totally of chili leaf, whereas chlorophyl-a content all of tested isolates was not significant. From its research showed there were corelation between colonization and leaf chlorophyll content, the higher percentage of endophytic fungus on leaf chili, it made higher the chlorophyl-b content and chlorophyl totally content of leaf chili.

Abstract

Seeds are a valuable plant material for agriculture. The Kuantan Singingi district has many local rice seeds that can be developed, but these have not yet passed standard testing. This study aimed to determine the physical and physiological qualities of the seeds of two local rice genotypes in Kuantan Singingi Regency. This research was conducted in a completely randomized design (CRD), which was repeated four times. The factor tested consisted of two rice genotypes: the white and yellow genotypes. เว็บสล็อต | R4shub The parameters observed were the percentage of the First Count Test (FCT) of germination capacity (GP), Maximum Growth Potential (MGP), Root and Shoot Growth Test (RSGT), and Seedling Growth Rate Test (SGRT). The collected data were analyzed by ANOVA at the 5% level and further tested by the LSD test. The results showed that FCT (%), GP (%), and Vigor (%) provide high figures according to SNI. Meanwhile, the IVT of all seeds on day 2 germinated. Based on the data from the RSGT and SGRT, all seed growth was normal.  Keywords: Kuantan Singingi, local seeds, viability, vigor

Abstract

Colorants are commonly added to food products to enhance their visual appeal and increase consumer interest. Among the various types of natural pigments, anthocyanins—derived from fruits, vegetables, flowers, and tuberous plants—have garnered significant scientific interest due to their vivid coloration and associated health-promoting properties. Nevertheless, anthocyanins exhibit considerable sensitivity to environmental variables, including temperature, pH, oxygen exposure, ultraviolet (UV) radiation, and interactions with other molecular constituents. A range of environmental stressors can accelerate the deterioration of anthocyanin pigments during processing and storage, leading to a decrease in colour intensity. To counteract these destabilizing influences, various encapsulation strategies have been developed to protect anthocyanins from degradation. Among these, spray drying is widely recognized for its efficacy in maintaining both the physicochemical integrity and biofunctional performance of anthocyanin molecules. This review discusses the strategic importance of encapsulation in enhancing anthocyanin stability and examines the primary degradation mechanisms relevant to their application in food systems.

Abstract

Amorphophallus titanum dan Amorphophallus gigas merupakan flora endemik Sumatera yang terancam punah. Perbanyakan tanaman melalui setek dapat digunakan untuk menunjang kegiatan konservasi. Keberhasilan setek ditentukan oleh konsentrasi zat pengatur tumbuh (ZPT) untuk menginduksi terbentuknya akar, corm dan tunas, sehingga kajian tentang konsentrasi ZPT penting untuk dipelajari. Penelitian ini bertujuan untuk mendapatkan konsentrasi IBA terbaik untuk menginduksi akar dan corm pada A. titanum dan A. gigas. Penelitian telah dilakukan dari bulan Juli-Oktober 2022. Penelitian disusun berdasarkan rancangan acak lengkap dengan perlakuan konsentrasi IBA yang terdiri dari 5 taraf yaitu: 5, 10, 15, 20 dan 25 mg L-1. Setek pada A. titanum menggunakan rachis dan petiole, sedangkan pada A. gigas hanya menggunakan rachis. Hasil penelitian menunjukkan bahwa setek petiole menunjukkan respons yang lebih baik dibandingkan dengan rachis dalam menginduksi terbentuknya akar pada A. titanum. Konsentrasi IBA 15 mg L-1 menghasilkan persentase berakar sebesar 80% pada setek petiole A. titanum dan 20% pada setek rachis A. gigas.Kata Kunci : biodiversitas, endemik, konservasi, punah, zat pengatur tumbuh

Abstract

Secondary forest is primary forest that managed for forest exploitation purposes, so there are many oil palm plantations that are directly adjacent to secondary forest. Hymenopteran parasitoid is a group of the most important insect in the Hymenoptera order, because of its role as natural enemies or biological control agents against insect pests in agricultural ecosystems, including oil palm plantations. The objective of this study was to understand the diversity, species richness and abundance of Hymenopteran parasitoids in oil palm plantations which adjacent to secondary forests. The research was a survey, the purposive sampling method to determine the research location, while to determine the sample points used a systematic random sampling method. For insect collection, insect nets and yellow pan traps were used. The research was carried out in oil palm plantations located in Gunung Selasih and Siguntur Village. In each research unit there were 10 sample points with a distance of each sample point was 100 m along the transect line. The results showed that the total number of Hymenopteran parasitoids collected was 199 individuals belonging to 23 families and 94 morphospecies. Braconidae and Ichneumonidae were the Hymenopteran parasitoids family which its members were found many in the present study.

Abstract

Pertumbuhan tanaman kakao sangat dipengaruhi oleh ketersediaan unsur hara di dalam tanah. Ketersediaan unsur hara ditentukan oleh sifat fisik, kimia dan biologi tanah. Pada tanah marginal seperti Ultisol memiliki tingkat ketersediaan unsur hara yang sangat rendah. Hal ini disebabkan oleh proses pelapukan yang intensif. Oleh karena itu, perlu dilakukan perbaikan kesuburan tanahnya. Salah satu upaya yang bisa dilakukan untuk memperbaiki kesuburan tanah Ultisol agar kakao dapat tumbuh dengan baik adalah dengan melakukan penambahan pupuk alam. Pupuk alam dapat berasal dari pemanfaatan sisa-sisa tanaman atau hewan. Salah satu diantaranya yaitu pemanfaatan limbah darah sapi, limbah ini belum banyak digunakan sebagai sumber pupuk alam. Penelitian ini dilaksanakan pada bulan November 2019 hingga April 2020, yang bertempat di kebun percobaan kampus 3 Universitas Andalas, Dharmasraya. Penelitian ini merupakan penelitian eksperimen yang disusun dalam Rancangan Acak Lengkap (RAL). Perlakuan yang dicobakan terdiri dari 5 taraf perlakuan yaitu: P0: 0 ml darah/L air P1: 40 ml darah/L air, P2: 60 ml darah/L air, P3: 80 ml darah/L air, P4: 100 ml darah/L air. Dari hasil penelitian diketahui bahwa penambahan pupuk cair darah sapi memberikan pengaruh terhadap pertumbuhan bibit kakao pada ultisol. Aplikasi pupuk cair darah sapi dengan dosis 40 ml – 100 ml pada tanaman kakao memberikan respon pertumbuhan yang lebih baik pada tanah ultisol, jika dibandingkan dengan tanaman yang tidak ditambahkan pupuk cair darah sapi. Hal ini dapat dilihat pada variabel pengamatan jumlah daun dan diameter batang. Dengan demikian pemanfaatan limbah darah sapi dapat dipertimbangkan sebagai salah satu sumber pupuk cair alami.
