Abstract

Ketersediaan sumber pakan yang rendah menjadi salah satu permasalahan yang dihadapi petani madu lebah A. dorsata di Kampar, Riau. Aktivitas lebah terdiri dari spatial learning atau pengenalan lingkungan, foraging atau mencari sumber pakan dan aktivitas migrasi. Penelitian bertujuan menganalisis aktivitas terbang lebah dan mengidentifikasi keanekaragaman polen yang ada di dalam madu. Pengamatan aktivitas terbang dilakukan dengan menghitung aktivitas keluar sarang, masuk sarang tanpa polen dan masuk sarang dengan polen selama 3 hari dengan 3 interval waktu. Polen didapatkan dari madu asal Kampar, Riau. Aktivitas lebah A. dorsata keluar sarang, masuk ke sarang tanpa polen dan masuk ke sarang dengan polen selama 3 hari paling tinggi berada pada pukul 11-12, yang merupakan bukan waktu terbang untuk mencari nektar dan polen pada umumnya. Aktivitas terbang meningkat seiring dengan meningkatnya suhu dan intensitas cahaya. Sebanyak 13 spesies tumbuhan yang menjadi sumber pakan A. dorsata terdiri atas habitus pohon, perdu, semak dan herba. Jumlah persentase polen paling banyak yang menjadi sumber pakan A. dorsata merupakan habitus pohon yaitu Pentace sp. (64%), Eucalyptus alba (22.9%) dan Elaeis guineensis (4%).

Abstract

Cinnamon (Cinnamomum burmannii) is an herbal plant that has a function, one of which is lowering glucose in the blood and warding off free radicals that cause oxidative stress. This study aims to determine the inhibitory activity of the enzyme compound α-glucosidase and the suppression of DPPH free radicals using the first, second, and third replications of cinnamon bark water extract (C. burmannii) as a natural source of antidiabetic drug candidates. The extraction method uses the infundation technique and is carried out using a spectronometer. The highest yield was obtained in the extraction of the first repeat, which is with an average of 0.674%, the yield did not differ markedly (p>0.05) with the second and third repeats. The highest results of total phenolic testing were obtained in the second repeat extraction of 100.374 GAE g-1, the results differed markedly (p<0.05) with the first and third repeats. The highest results of testing antioxidant activity were obtained at the extraction of the first repeat which was 9.012 mg of AAE g-1, the results differed markedly (p<0.05) with the second and third repeats. The highest result of testing of enzyme inhibition activity α-glucosidase was found in the extraction of the first repeat which was 99.650%, the results did not differ markedly (p>0.05) with the second and third repeats.

Abstract

Temulawak (Curcuma xanthorrhiza) is known to be used as ingredient in Jamu and traditionally utilized to cure a range of illness. The global market demand for the rhizome of the temulawak affecting the urgency of sustainable rizhome production. The aim of this research was to analyze the effects of root endophytic and arbuscular mycorrhizal fungi on growth and rhizome curcumin content of the temulawak. There were five fungal inoculation treatments on C. xanthorrhiza seedling grown in sterilized and unsterilized growth media. They were root endophytic fungi A. niger (A), Glomus sp. (G), combination of A. niger and AMF Glomus sp. applied at the same time (GA) and at different time (G-A) and control. The experiment was conducted under greenhouse condition. The plant growth parameters, fungal colonization, and rhizomes curcumin content were measured. The result showed that there was a significant interaction between fungal inoculation and control treatments. In general, fungal inoculation on both sterilized and unsterilized growth media increased the plant growth and rhizomes curcumin content. On the sterilized growth media, C. xanthorrhiza inoculated by A. niger showed the best growth parameter. On the other hand, the best growth parameter on the unsterilized media was showed by C. xanthorrhiza inoculated by mixed fungal inoculums. The highest amount of curcumin content was showed by C. xanthorrhiza inoculated by Glomus sp. as a single inoculation.
Kepadatan dan Persebaran Parmarion pupillaris pada 10 Jenis Sayuran di Desa Dlangu, Kecamatan Trawas, Kabupaten Mojokerto: Density and Distribution of Parmarion pupillaris on 10 Species of Vegetables in Dlangu Village, Trawas District, Mojokerto Regency Novi; Oktavia Pradikaningrum, Novi; Chikmawati, Tatik; Widarto, Tri Heru

Abstract

Vegetables are one of horticultural commodities having a relatively short life cycle. Pest is one of the problems faced in vegetable cultivations. One specie that often attack vegetables is Parmarion pupillaris (Mollusca). It is a semi-slug that has a small bump transparent coat and shell on its back. These semi-slugs are often found eating leaves, stems, flowers and fruit of the vegetables. The aims of the study were to study distribution patterns, density, feeding activity and size distribution of the P. pupillaris in 10 species of vegetables in Dlangu Village, Trawas District, Mojokerto Regency. The observation plots were chosen randomly by determining three plots of each species sized 1m x 1m plot with three replications. Direct observation of feeding activities was conducted at night. Measurement of body length was conducted directly at the time of observation. Data analysis of density and distribution patterns used the quadratic method and Morisita Index. The results of this study showed that the highest P. pupillaris density found in tomato (Solanum lycopersicum), 8.7 ind / m2, while the lowest density was found in corn (Zea mays), 0.5 ind / m2. P. pupillaris found had medium and small sizes. Distribution patterns of semi-slugs based on the Morisita Index is categorized as clump.

Abstract

The study was conducted to observe the growth, fruiting body production and nutritional contents of white oyster mushroom (Pleurotussp., wild HS isolate) grown on 300 g of mixed substrate between sengon sawdust (Albizia chinensis) (SGKS) and dried banana leaves or klaras (Musa sp.) and compared with SGKS, the commonly used single substrate. Both substrates were added with 15% bran, 1.5% lime and 1.5% gypsum. The production of mushroom fruiting bodies on mixed substrates was higher than that of single substrate with biological efficiency of 27.24% and 22.00%, respectively. Likewise, the protein content of the mixed substrate was much higher than that of the single substrate, 19.6% and 10.9%, respectively, while the crude fiber and carbohydrate contents were slightly higher in the single substrate, respectively 8.76% and 54 ,37%. Further research needs to be carried out on a mixed substrate of at least 500 g to get a more complete pattern of the production and biological efficiency.

Abstract

Penggunaan pewarna alami untuk tekstil memiliki keunggulan, antara lain ramah lingkungan. Penelitian ini bertujuan menganalisis potensi pemanfaatan enam jenis tumbuhan sebagai pewarna alami tekstil. Penelitian menggunakan bahan daun dari pucuk merah (Syzygium oleana), kayu manis (Cinnamomum burnamii), alpukat (Persea americana), jakaranda (Jacaranda mimosifolia), kayu putih (Eucalyptus sp.) dan lanang (Oroxylum indicum); tiga jenis mordan yaitu tawas, tunjung, kapur sirih; dan tiga jenis kain yaitu katun combed, katun primisima, dan sutera. Tahapan penelitian meliputi ekstraksi zat warna dari tumbuhan dan pencelupan kain yang sebelumnya telah diberi perlakuan mordan. Potensi sebagai pewarna dianalisis berdasarkan warna yang dihasilkan dan stabilitas warna. Identifikasi warna dilakukan menggunakan RGB (Red Green Blue) Color Chart Reader. Stabilitas warna diukur dengan uji tahan luntur warna terhadap proses pencucian mengacu SNI ISO 105-C06-2010. Penerapan ekstrak pewarna pada jenis kain berbeda yang diberi perlakuan mordan berbeda-beda menghasilkan variasi warna. Selain itu, pemberian mordan juga berpengaruh baik terhadap ketahanan luntur warna akibat pencucian. Semua ekstrak menghasilkan warna dan ketahanan luntur terbaik pada kain sutera yang diberi perlakuan mordan tunjung. Semua jenis tumbuhan dalam penelitian ini berpotensi sebagai pewarna tekstil, namun untuk mendapatkan hasil terbaik dalam penggunaannya perlu mempertimbangkan jenis kain dan mordan.
