Abstract

Oyster mushroom is a commodity that is in high demand in the community. Oyster mushroom production in Indonesia is decreasing year after year as wood sawdust, which is often used as a media for oyster mushrooms, becomes increasingly difficult to get. Bamboo has a nutrient content similar to wood sawdust; therefore, bamboo sawdust can be utilized as a media for growing oyster mushrooms. The aim of this research was to find the best mixture of bamboo and wood sawdust for the growth and yield of oyster mushrooms (Pleurotus ostreatus). This research was carried out from July to October 2023 at Lampung State Polytechnic. This study used a randomized block design with one factor that was repeated four times. The following treatments were used: C0 = 100% wood sawdust, C1 = 90% bamboo sawdust + 10% wood sawdust, L2 = 80% bamboo sawdust + 20% wood sawdust, C3 = 70% bamboo sawdust + 30% wood sawdust, C4 = 60% bamboo sawdust + 40% wood sawdust, and C5 = 50% bamboo sawdust + 50% wood sawdust. The collected data was analyzed using analysis of variance (ANOVA) and then evaluated with LSD test at the 5% level. The results of this research were that the treatment of C5 = 50% bamboo sawdust + 50% wood sawdust gave the best results on the parameter of the mycelium growth rate, the time of the fruit body initiation (FBI), the number of hoods, the diameter of the hood, the thickness of the hood, the harvest, the harvest weight per baglog, and the total harvesting per plot.

Abstract

Philodendron xanadu is one of the leaf ornamental plants that much liked by society. Apart from being an ornament, P. xanadu also functions as an absorbent of toxic compounds contained inside the room. The potential development of P. xanadu is quite promising because the plant is widely used for decorating rooms and garden-forming elements.  The growth rate of P. xanadu which derived from the separation of saplings is very slow, where the plant height is barely increased, but the addition number of saplings is very rapid / numerous. These conditions are unfavorable when used as an ornamental plant because the beauty of the plant is not optimally expressed. To overcome this, it is necessary to conduct research on the use of gibberellic acid (GA3) and naphthalmylene acetic acid (NAA) to spur the plant growth.  The purpose of this study was to determine the influence of the use of GA3 and (NAA) to the growth of P. xanadu. The study was arranged factorial (2 factors) with a group randomized environment design. As the first factor is three levels of GA3 (0, 50, and 100 mg.l-1), and the second factor is 3 levels of NAA (0, 50, and 100 mg.l-1). Each experimental treatment was repeated 4 times. The results showed that the given of NAA and GA3 concentrations of 0, 50, and 100 mg.l-1 had no effect on the growth (leaf length) and the number of saplings P. xanadu. Keywords: GA3, NAA, Philodendron xanadu

Abstract

The oyster mushrooms are generally cultivated on baglog medium, which is produced from leftover wood sawdust. The oyster mushroom may thrive in a variety of cellulose, hemicellulose, and lignin-containing substrates medium. The purpose of this study was to determine the effect of leftover bamboo powder waste on the proximate content of oyster mushrooms when it was utilized as a growing medium in mushroom baglogs. This study was carried out at the Lampung State Polytechnic of Mushrooms Kubung from August to October 2022. The test material consisted of oyster mushrooms collected from mushroom baglogs constructed of 100% sawdust, 100% coarse bamboo waste, 100% fine bamboo waste, and 50% coarse bamboo waste + 50% fine bamboo waste. Three harvests of oyster mushrooms were made on various media types for testing purposes in the lab. According to this study's findings, oyster mushrooms grown on bamboo powder media have a better value than oyster mushrooms grown on wood sawdust media in terms of their proximate content of water, protein, fat, and carbohydrates. Key-words: Bamboo Powder, Nutrition, Oyster Mushroom, Proximate, Wood Sawdust INTISARI Jamur tiram umum ditumbuhkan pada media baglog yang berbahan dasar limbah serbuk gergaji kayu. Jamur tiram memiliki kemampuan untuk tumbuh di berbagai jenis media yang mengandung selulosa, hemiselulosa, dan lignin. Tujuan penelitian ini untuk mengetahui pengaruh dari limbah serbuk bambu yang digunakan sebagai media tumbuh dalam baglog jamur pada kandungan proksimat jamur tiram. Penelitian ini dilaksanakan pada bulan Agustus – Oktober 2022 di Kubung Jamur Politeknik Negeri Lampung. Bahan uji yang digunakan adalah jamur tiram yang dipanen dari baglog jamur berbahan dasar utama Limbah bambu kasar 100%; Limbah bambu halus 100%, Limbah serbuk kayu 100%; dan Limbah bambu kasar 50%+Limbah bambu halus 50%. Jamur tiram yang dipanen pada setiap jenis media dilakukan tiga kali pengulangan untuk keperluan pengujian di dalam laboratorium. Kesimpulan dari penelitian ini adalah kandungan proksimat kadar air, protein, lemak dan karbohidrat jamur tiram yang ditumbuhkan pada media serbuk bambu memiliki nilai lebih tinggi dibandingkan dengan jamur tiram yang ditumbuhkan pada media serbuk gergaji kayu. Kata kunci: Gizi, Jamur tiram, Proksimat, Serbuk bambu, Serbuk gergaji kayu
