Abstract

Kacang tanah (Arachys hypogaea L.) varietas lokal Tuban merupakan salah satu tanaman budidaya yang memiliki potensi ditanam pada lahan marginal bekas tambang kapur karena memiliki adaptasi yang tinggi pada kondisi kering dan alkali. Secara biologi, fisika dan kimia lahan bekas tambang kapur memiliki kesuburan tanah yang rendah. Salah satu upaya untuk meningkatkan kesuburannya adalah dengan menggunakan pupuk hayati yang adaptif  pada kondisi lahan bekas tambang kapur. Tujuan dari penelitian ini adalah untuk mengetahui potensi pemanfaatan PGPR dari tanaman pioneer yang tumbuh  di lahan bekas tambang kapur terhadap pertumbuhan vegetatif  kacang tanah (Arachys hypogaea L.) varietas lokal Tuban pada media tanam bekas tambang kapur. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan (25%, 50%, 75% dan 100%) dan satu kontrol (0%) masing-masing lima kali ulangan. Hasil penelitian ini menunjukkan bahwa berdasarkan uji MANOVA pemberian berbagai konsentrasi PGPR tidak memberikan pengaruh yang signifikan terhadap tinggi dan jumlah daun tanaman.  Sementara berdasarkan uji statistik korelasi Spearman memiliki korelasi yang signifikan terhadap warna daun. Semakin tinggi konsentrasi PGPR yang diberikan menghasilkan warna daun yang semakin hijau berdasarkan skala Leaf Colour Chart (LCC).

Abstract

The process of composting inked waste paper can be done because inked waste paper contains organic material in the form of cellulose, hemicellulose, lignin and ash compounds. But unlike other organic materials inked used paper has undergone various chemical processes in its manufacture so it needs to be done soaking treatment in advance to reduce the content of various chemicals. In this case inked scrap paper is soaked with distilled water added with activated charcoal, corn cobs charcoal, PGPR and rumen liquid. The PGPR was then added to a phosphate buffer of pH 7 and incubated for 7 days at room temperature without exposure to sunlight. Rumen fluid is taken at the Jenu Slaughterhouse in Tuban Regency, this liquid is taken directly after the cow is slaughtered and put into a flask then phosphate buffer pH 7 is added and incubated for 7 days at room temperature and not exposed to sunlight. Provision of activated charcoal, corn cobs charcoal and PGPR can be done in the process of precomposting inked waste paper with a cow rumen liquid starter without causing pH and temperature fluctuations. Keywords: Activated Charcoal, Corncob Charcoal, Pgpr, Rumen Liquid, Waste Paper

Abstract

Bakteri tanah memiliki kemampuan sebagai agen pengkhelat senyawa beracun, penyedia unsur hara bagi tanaman, pelindung tanaman dari bakteri patogen dan penghasil zat pengatur tumbuh bagi tanaman. Genangan pada lahan pertanian menyebabkan perubahan komposisi dan aktivitas bakteri tanah. Selain itu, genangan dapat menyebabkan cabai rawit mengalami stres oksidatif. Sehingga genangan secara umum dapat menyebabkan cabai rawit mengalami gangguan pertumbuhan dan perkembangan. Meskipun secara alami cabai rawit dapat pulih dari stres genangan namun memakan waktu yang kebih lama sehingga menimbulkan kerugian bagi petani. Pemberian Plant Growth Promoting Rhizobacteria (PGPR) dapat membantu mempercepat proses pemulihan cabai rawit pasca stres genangan. Namun tidak semua bakteri dalam PGPR dapat beradaptasi terhadap kondisi lingkungan rhizosfer cabai rawit pasca genangan. Oleh karena itu penelitian ini dilakukan untuk karakterisasi bakteri di rhizosfer cabai rawit pasca genangan dan aplikasi PGPR. Metode dalam penelitian ini meliputi aklimatisasi cabai rawit di greenhouse, pembuatan larutan PGPR, penggenangan parsial cabai rawit selama 48 jam, drainase cabai rawit selama 24 jam, aplikasi larutan PGPR pada rizhosfer cabai rawit, pengambilan sampel media tanam, isolasi bakteri media tanam, purifikasi isolate bakteri, serta karakterisasi bakteri berupa pengamatan morfologi dan uji biokimia. Data yang diperoleh berupa karakteristik morfologi dan uji biokimia selanjutnya dianalasisis secara deskriptif. Hasil penelitian menunjukkan bahwa terdapat 13 isolat yang diperoleh berbentuk coccus, bacil dan coccobacil, hasil uji katalase seluruh isolat positif, 12 isolat gram positif dan 1 isolat gram negatif, respirasi (aerob 5 isolat, anaerob 4 isolat, aerob fakultatif 3 isolat dan 1 isolat aerotolerant anaerob)

Abstract

Traditional food is one of the cultural products that was created to meet primary human needs by involving local wisdom. Various types of traditional food are processed from plants taken from the surrounding environment and other places. Local communities have specific interactions and perceptions of plants as ingredients for their traditional foods. The goal was to determine the diversity, the categories of utilization, the organs used, the preparation methods, and the Cultural Significance Index (ICS) of plants in traditional Tuban food ingredients. This research was conducted by surveying 117 respondents from 20 sub-districts in Tuban Regency, followed by in-depth interviews with 20 traditional food makers in Tuban. The data obtained is in the form of qualitative data in the form of local knowledge of the Tuban people regarding plants in their traditional food ingredients, while quantitative data is in the form of the Cultural Significance Index (ICS). The results showed that there were 15 families consisting of 10 species of plants in traditional Tuban food, all of which were cultivated plants, the most used category of plants as spices and the organs most used were seeds and the highest ICS value was Oryza sativa L.

Abstract

Cayenne pepper is known to be susceptible to various types of flooding by showing various negative responses. This study seeks to ascertain the influence of PGPR on the adverse effects of floods on cayenne pepper as a means to mitigate farmer losses. The study used a completely randomized design on cayenne pepper which was given treatments in the form of control without PGPR (K(-)), control with PGPR (K(+)), flooding treatment for 2 days with PGPR 7 days later (P(+)) and without PGPR (P(-)) each with 10 reps. The two-way ANOVA test reflected that flooding had a significant effect on the response of plant height increase, petiole curvature angle, and wilting. In contrast, PGPR application had a significant effect on plant height increase and number of branches. The interaction of flooding and PGPR application significantly affects the increase in plant height but not the number of leaves, the number of branches, the angle of curvature of the petiole, and wilting. It was concluded that the application of PGPR can reduce the adverse effects of flooding on cayenne pepper farming.

Abstract

Pioneer plants are plants with high adaptability, so they can grow in disturbed environments, such as ex-limestone mining areas. This adaptability is supported by the ability of these plants to associate with soil bacteria in their rhizosphere area. The presence of these bacteria can support the growth of pioneer plants on disturbed land. The purpose of this study was to characterize the soil bacteria around the rhizosphere of pioneer plants in the former limestone mining areas. Soil samples in the rhizosphere area of 5 pioneer plants from ex-mining lime were then isolated using the Pour plate method to obtain bacterial isolates. The bacterial isolates obtained were then identified their colony morphology. Based on the results of colony morphological identification, 21 isolates were obtained from the rhizosphere of 5 pioneer plants from the former limestone mining area. The highest number of isolates was obtained from the rhizosphere of the Waltheria indica with 9 isolates, 8 isolates of each Lamium barbatum and Digitaria sanguinalis, 7 isolates of Chromoleana odoratum, and 5 isolates of Tridax procumbens.
