Wax apple Delima and Citra Cultivars are two superior non-climacteric tropical fruit commodities from Demak Regency which have similar morphological characters but have different fruit characteristics. Identification wax apple cultivars from Demak regency using DNA barcoding approach has not been researched yet. The aims of this research are to analyze the morphological similarities of wax apple between Delima and Citra cultivars and to identify genetic variations of wax apple Delima and Citra using trnL-trnF intergenic spacer for molecularly authentication. The results shown that there were no differences in the environmental parameters of the wax apple two cultivated area in Demak Regency. According to the morphological approach, the Delima and Citra cultivars in Demak Regency were grouped separately into Delima and Citra clusters with a similarity index of 61.5% (Citra cultivars) and 60.5% (Delima cultivars) and separated based on the origin of their cultivation area. Genetic variations between wax apple Delima and Citra in Demak Regency consisted of deletions (9delA 17delA) and conserved P6 loop in all compared cultivars. The possibility of heteroplasmy R (A,G) found at 73 nucleotide number in Delima Betokan cultivar and Citra cultivars (Betokan and Jungpasir). Meanwhile, Delima Jungpasir cultivar is K (G,T). There were P8 stem-loops with different lengths between Delima cultivars (Betokan and Jungpasir) and the same length in Citra cultivars (Betokan and Jungpasir). Therefore, the trnL-trnF intergenic spacer has not been thoroughly used in wax apple Delima and Citra authentication due to the presence of a secondary structure which causes the loss of the electropherogram signal so that the nucleotide sequence cannot be read.

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.

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.

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.

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.

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.
檀香(Santalum album L.)生长在东努沙登加拉，是一种被称为hau meni的特有植物。檀香被用作雕刻和香水的基础，其中含有具有独特香气的精油。拥有的优势导致售价非常昂贵。这导致了檀香木的开发，导致檀香木的数量减少。通过种苗和苗圃进行了重新种植的努力，但成功率仍然很低。通过体外实验的努力有望帮助保护这种植物。研究了施用液体有机肥对檀香生长的影响及促进檀香萌发的最佳浓度。通过添加不同类型的LOF，并随浓度变化进行研究。在Murashige和Skoog (MS)培养基上添加浓度为2ml的Nasa是促进种子萌发的最佳浓度，对种植后14天(DAP)有响应;在添加浓度为2ml的lontar时，对毛囊外观有响应。在MS培养基上添加碱型LOF对檀香植株的发芽率有82%的影响，而龙骨型LOF对檀香植株的营养生长有促进作用。

The resources of the blue swim crab are currently under pressure on survival due to the increasing effort to catch in nature. Management of blue swim crab resources requires information on the biological conditions of the crab to determine the size, sex, and number that can be caught. This study aims to analyze the structure of carapace width concerning differences in sex, gonad maturity level, and crab condition factors. The method used is the method of observation by measuring the length, weight, and maturity level of the gonads and then analyzed descriptively. The results showed that the size of the crabs was included in the category of juvenile to adult crabs for both male and female crabs. The growth pattern of male crabs with a coefficient of b value of 2.47 and female crabs of 2.78 shows that the growth patterns of crabs in Pulau Baai waters are negative allometric. Most of the female crabs are in the immature stage of the gonads, so the condition factor for the female crabs tends to be lower than the male crabs, this is because most of the female crabs have just passed the spawning phase.
