Abstract

Peningkatan polutan logam berat kadmium (Cd) di persawahan menjadi masalah lingkungan yang serius karena dapat menimbulkan toksisitas dan berakibat pada penurunan pertumbuhan tanaman pangan yang tidak toleran. Gejala toksisitas Cd pada tanaman dapat dikurangi dengan memanfaatkan unsur benefisial seperti silikon (Si). Namun, peran Si dalam mengurangi gejala toksisitas Cd pada padi ‘Cempo Merah’ belum banyak diteliti. Tujuan penelitian ini yaitu mengkaji peran Si dalam meningkatkan pertumbuhan dan kadar klorofil padi ‘Cempo Merah’ yang tercekam logam berat Cd.Penelitian ini menggunakan desain Rancangan Acak Lengkap 2 Faktorial, yakni perlakuan 3CdSO4.H2O­ dan CaSiO3 (masing-masing dengan konsentrasi 0, 50, dan 100 mg.kg-1 tanah), dengan 3 kali ulangan. Data penelitian dianalisis menggunakan ANOVA (analisis sidik ragam) dan uji DMRT (Duncan Multiple Range Test) pada p0,05. Hasil penelitian menunjukkan bahwa perlakuan Si (100 mg.kg-1 tanah) efektif meningkatkan pertumbuhan dan kadar klorofil padi ‘Cempo Merah’ baik dalam kondisi tidak tercekam maupun tercekam logam berat Cd. AbstractIncreasing cadmium (Cd) in rice fields become a serious environmental problem because it can cause toxicity and decrease the growth of intolerant food crops. These toxicity symptoms can be reduced by utilizing beneficial elements such as silicon (Si). However, its role in rice 'Cempo Merah' has not been much studied. This study aimed to examine the role of Si in increasing the growth and chlorophyll content in the rice ‘Cempo Merah’ under Cd stress. This study used a Complete Randomized Design, two factorials, namely 3CdSO4.H2O and CaSiO3 (each with 0, 50, and 100 mg.kg-1 of soil concentrations), with 3 replications. The research data were analyzed using ANOVA and Duncan’s test at p 0.05. The results showed that Si (100 mg.kg-1) effectively increased the growth and chlorophyll content in rice both under Cd stress and normal conditions.  Keywords: silicon, cadmium, growth, chlorophyll, rice AbstrakPeningkatan polutan logam berat kadmium (Cd) di persawahan menjadi masalah lingkungan yang serius karena dapat menimbulkan toksisitas dan berakibat pada penurunan pertumbuhan tanaman pangan yang tidak toleran.

Abstract

Sandalwood (Santalum album L.) which grows in East Nusa Tenggara is an endemic plant known as hau meni. Sandalwood is used as a base for carving and perfume containing essential oils that have a distinctive aroma. The superiority that is owned causes the selling price is very expensive. This causes exploitation which results in a diminishing number of Sandalwood trees. Efforts to replant have been carried out through seedlings and nurseries but the success rate is still low. Efforts through invitro are expected to help conserve this plant. To determine the effect of giving Liquid Organic Fertilizer (LOF) on the growth of Sandalwood and the best concentration in promote germination. The study was conducted by adding different types of LOF with concentration variation. The addition of Nasa with a concentration of 2 mL which is the optimal concentration in promote the germination with the response at 14 Days After Planting (DAP) on Murashige and Skoog (MS) medium while on the addition of lontar the concentration of 2 mL shows the response of the appearance of plumula. The addition of base type LOF on MS medium affected 82% germination percentage while lontar type LOF stimulated vegetative growth of Sandalwood plants.

Abstract

Microplastics are a form of new pollution that the Indonesian people are not aware of. The factors for the entry of microplastics into pond waters are water sources, anthropogenic activities, and pond cleanliness. The purpose of this study was to determine the abundance of microplastics, the color and shape of microplastics, and the types of microplastic polymers found in sediment, water, and the digestive tract of milkfish (Chanos chanos) in Sidoarjo ponds. The average abundance of microplastics in sediment samples obtained from semi-intensive ponds is 300 particles per 50 grams, while the sediment samples from traditional ponds are 613 particles per 50 grams. The average abundance of microplastics in the semi-intensive pond water samples was 2.1 particles per 20 liters and in traditional ponds was 2.3 particles per 20 liters. The average abundance of microplastics in the milkfish (Chanos chanos) samples from the Semi-Intensive Pond was as many as 6 particles per tail, while the Traditional Pond had 9.5 particles per tail. In this study, four colors of microplastics were found, namely blue, black, red, and transparent, while the microplastics obtained were fiber, fragment, and filament. The types of microplastic polymers encountered in this study were dominated by polyamide or nylon polymers. In sediment samples from both ponds, we found the presence of Polyamide or Nylon polymers, namely Polystyrene and Polyamide or Nylon, and in the digestive tract of milkfish (Chanos chanos), namely Polyamide or Nylon.

Abstract

Cayenne pepper (Capsicum frutescens L.) is a horticultural plant that has high economic value and contains nutrients that the body needs. Cayenne pepper is one of the leading national horticultural commodities, so it is necessary to increase the production of cayenne pepper appropriately. The obstacle that is often faced in the production of cayenne pepper is the disruption of the production of cayenne pepper caused by the attack of anthracnose disease. Anthracnose disease or fruit rot caused by the fungus Colletotrichum capcisi Sydow can result in yield losses ranging from 20-90%. Trichoderma harzianum Rifai. is a soil saprophytic fungus that naturally can be used as a biological agent, because it has antagonism against pathogens in the form of competition for space and nutrients, mycoparasites and antibiosis. The experimental results in the laboratory showed that the biological agent Trichoderma harzianum Rifai was able to suppress the development of anthracnose disease.

Abstract

This research aims to determine the potential of bacterial isolates from Marina beach seawater to be used as natural textile dyes and to test their antibacterial ability. The media used for culturing bacteria is a zobel synthesis medium with a mixture of seawater. The results of the isolation and extraction of color pigments obtained a red color with a characteristic wavelength of 535 nm and has a variety of chemical content results. Pigment immersion trials using 3 types of fabric, namely cotton, primisima and dobby fabric. The results of immersion with ethanolic solvent obtained optimum results for 12 hours and with the addition of mordant (Fe.H2O4S.7H2O), the color of the fabric is strong enough to withstand washing with detergent and sunlight. From the results of the study, data showed that the dyed primisima fabric gave a reduction or inhibition of the growth of E. coli bacteria by 9% while the inhibition of S. aureus bacteria was 116%. The pigment has the potential to be used as a dye for batik cloth with the provisions of optimizing to find the right reinforcement or mordant. This study has implications for the discovery of red pigment-producing bacteria from the isolation of seawater at Marina Semarang beach.

Abstract

Bogor Botanic Gardens is an ex-situ plant conservation area in Indonesia. Since BBG is 103 years old, many collections are 100 years old or older. These antique collections may sustain damage, such as broken or collapsing, endangering visitors and employees. As a result, monitoring tree health at BBG is a critical task. According to the tree health monitoring data, 73 of 244 trees were further checked using the PiCUS Sonic Tomograph. Trees from the Fabaceae (31%) and Myrtaceae (10%) families were the most frequently checked. Walnuts trees from the Burseraceae family had the most specimens (47,94%). The PST effectively provides an immediate picture of the stem condition by calculating solid and decaying wood percentage values.
