Abstract:

Silk fabric was dyed with the colourant extracted from Laccifer Lacca Kerr. by using post-mordanting process and pad-dry technique. The effect of metal mordantats at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Laccifer Lacca extract showed a light pink shade, while those dyed with alum and stannous chloride produces pinkish-red colour. Silk mordanted with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between good and excellent for dyed fabric.The results confirmed that natural dyes from Laccifer Lacca Kerr. extract have potential applications for silk fabric dyeing and producing ultraviolet (UV) protective silk fabric.

Abstract:

Laccifer lacca has generally been used as pigmenting, coloring agent and dying in chemical industry. Although, it has wide range of industrial applications, but inappropriately, due to lesser availability of data, it has been ignored. Keeping in mind, the wide application of Laccifer lacca, we tried to report the in-silico anti-cancer effects. The experimental techniques used to determine the structure was X-RAY diffraction. The reported resolution of this entry is 2.80 Å. Percentile scores (ranging between 0-100) for global authentication metrics of the record. In silico have a good pool to explore various parameters in molecular docking. We have performed in silico analysis of the active components of Laccifer lacca against the cervical, breast and lung cancer proteins and also found that lac extract enhances the production of anti-inflammatory markers and the increase is significant when compared to the standard vinblastine. It has been demonstrated by Lala and colleagues that a short lived molecule nitric oxide can result in the progression of human tumours. Therefore, the prominent antioxidant activity of phytochemical that can act as inhibitors of nitric oxide production can act as anticancer therapeutics. Both methanolic and aqueous extract shows significant anticancer effect on the hela, MCF-7 & A549 cells suggesting them as potential anticancer therapeutics for future. Keywords: Laccifer lacca, In-vitro & In-silico analysis, Carcinogenesis, Anti-inflammatory, Molecular Docking.

Abstract:

Abstract A new method has been proposed for detection of lac color in food. Lac color is a natural color additive derived from a secretion of the insect Coccus Laccae (Laccifer lacca Kerr). It is extracted from food with methanolic oxalic acid and eluted from a column of Amberlite XAD-2 with the same solvent. The fraction containing the lac color is treated with diazomethane to produce 2 reddish-orange markers. The marker species in the reaction mixture are detected by both thinlayer chromatography and reverse-phase liquid chromatography.

Abstract:

Lac insects (Laccifer lacca Kerr) live parasitically on “kosambi” plants, and produce resins that are called lac. Lac are used for electronics, printing, textile, clothing, cosmetics, and food industry. The insects also live on various plants. The goal of this research was to evaluate the population quality of Lac insect that live on three host plants. The best parameter for population quality was biomass or lac production. Three host plants were inoculated by broods. The result showed that “kosambi” was the best host plant for the insect due to higher biomass (i.e lac production) than “kabesak putih” and “kabesak hitam” plants.

Abstract:

Cold-pad-batch technique of silk dyeing fabric with two natural dyes (Laccifer lacca Kerr. And Garcinia dulcis (Roxb.) Kurz bark) using pre-mordant are performed using 3 different mordants namely, alum, tartaric acid and ferrous sulfate. The study showed that color intensity (K/S) slightly increased when the batching time increased from 1 to 24 hours. Dyed silk fabrics have different color shades depending on the types of mordant applied. Ferrous sulfate and alum was found to be the best mordants for improvements of color depth. Various fastness properties (wash, crock and light) of the dyed silk fabrics have also been investigated.

Abstract:

Kutu lak (Laccifer lacca Kerr) (Homoptera: Kerriidae) merupakan serangga yang hidup secara parasitik pada tanaman inangnya. Serangga tersebut menghasilkan resin alami yang kompak dan tebal, yang menempel pada cabang tanaman tempat hidupnya yang biasa disebut lak. Lak cabang merupakan resin alami dari hasil sekresi serangga L. lacca berupa lapisan tebal lak yang membungkus ranting-ranting tanaman inang. Serangan parasitoid dan predator terhadap kutu lak berdampak langsung pada penurunan produktivitas lak. Penelitian ini bertujuan untuk mengidentifikasi parasitoid dan predator yang menyerang kutu lak, dan menghitung tingkat parasitisasi di BKPH Kabuaran dan Taman, KPH Probolinggo, Perum Perhutani Unit II Jawa Timur. Sampel lak cabang diambil dari BKPH Kabuaran dan Taman masing-masing sebanyak 200 sampel lak cabang. Masing-masing lak cabang dimasukkan ke dalam tabung reaksi. Pengamatan parasitoid yang keluar dari lak cabang dilakukan dalam tabung reaksi. Famili parasitoid yang dominan ditemukan, yaitu Aphelinidae, Encyrtidae, dan Eulophidae. Predator yang ditemukan pada kutu lak terdiri atas Famili Lathridiidae (Coleoptera), Cosmopterigidae, dan Noctuidae (Lepidoptera), Nabidae (Hemiptera), serta Chrysopidae (Neuroptera). Jumlah kumulatif parasitoid di lapangan lebih banyak (5.900 individu) dibandingkan dengan di gudang (5.263 individu). Pertambahan individu parasitoid tertinggi dari lapangan dan gudang terjadi pada pengamatan hari ke-7 sampai hari ke-17. Tingkat parasitisasi kutu lak di lapangan dan gudang tergolong tinggi dengan nilai rata-rata sebesar 93% dan 96%. Dapat disimpulkan bahwa kutu lak yang berasal dari lapangan maupun gudang mengalami serangan parasitoid yang sangat tinggi.

Abstract:

Lac is a non-timber forest product derived from the secretion of Laccifer lacca insects that are cultivated in kesambi tree (Schleicera oleosa Merr). Low lac production in Indonesia due to poor conditions of host plant indicated by poor growth symptoms, yellowing, and falling leaves. The aim of this research was to study the effect of molasses injection on the growth and vitality of kesambi tree. Molasses were injected into the plant using passive liquid injection methods. Pre-research activities were carried out by the tree trunk injection in 0.5, 1.5, and 2 meters above the ground using gentian violet to determine the best stem injection position, while the main research activity was performed by injection of the kesambi tree trunk using molasses in concentrations of 5, 10, 15% and water as control. The parameters measured at the pre-study was translocation length of gentian violet whereas at the main research were the volume uptake, the increase of branch diameter growth, total sugar content and chlorophyll content. Pre-research results showed that 1.5 meters above the ground is the best injection position. The main research results indicated that the highest volume uptake was water followed by others treatments. Molasses injection at concentration of 10% gives better effect on the increase of branch diameter growth (4.3 mm), obtained sugar content in 18.46%. The vitality of kesambi tree also increased by the molasses injection at concentration of 10%. It was shown by thein creased of chlorophyll a (1.117 mg/g), b (0.416), carotene (0.365), and Anthocyanin (0.094 mg/100g).

Abstract:

With increased awareness about the environment, raw materials from petroleum based synthetics and the "green" quotient of consumer products have developed, shellac or shellac modified resins have gained importance due to their unique nontoxic and hypoallergenic properties. Shellac is water soluble, biologically degradable and has film forming, excellent adhesion, hardness, high gloss and superior in electrical properties. Shellac or shellac modified resins are also compatible with other resins and can be cross linked making them a wider applications. Shellac is abundant in Thailand, China and India, which produced from lac insects, Laccifer Lacca. The resinous secretion can be purified to become shellac. The main structure of shellac consists of polyesters and single esters that have hydroxyl and carboxyl groups [1, . Shellac was first used as a wood polish for music instruments and furniture and later for uses in spar varnishes with antifouling properties for ship paints, phonographic records, wood and wallpaper paints, printing inks, resins for electrical applications and floor polishes. Currently, new applications for using are such as child-safe paints and inks and the coating of fruits and vegetables, food and confectionary, pills, tablets and vitamins in the pharmaceutical industries. Bleached shellac has been widely used in pharmaceutical and cosmetics instead of native shellac due to the whiteness. However, conventional method for bleached shellac used many solvents [3, . Therefore, the aim of this study was to explore a new technique in order to avoid the use of organic solvent prior to the process of bleaching. The comparison was made between bleaching by the conventional and the new methods. The studied properties were acid value, viscosity, color change, water vapor permeability, chemical structure and powder x-ray diffraction.

ABSTRACTPhysical and Ecological Approaches to Using Tamarinds as Street Trees around the Sidewalk in Puputan Badung Parks, DenpasarMany streetscapes in Indonesia cities used tamarinds (Tamarindus indica L.) tress as soft scape elements and Denpasar city is also one of them. This paper is concerned with the use of tamarinds species in street trees, especially it uses around the Puputan Badung sidewalks. The objectives of this paper were to identify the positive impact of tamarinds physically and ecologically on the environment. A survey methods was employed to obtain information about the existing trees. Descriptive methods was used to analyze trees character physically and ecologically and also its suitability based on literature study. Study results showed that there were sixteen individuals of tamarinds found along the sidewalk in Puputan Badung parks. The trees distributed as many as four individuals on northern and southern part, six individuals on eastern part, and two individuals on western part of the park. Some physical characteristic of the trees have been identified, i.e. vase canopy shape to provide tree canopy cover and avoid sun glare effect, fine plant texture to expand space impression, and slow stem growth. In addition, trees ecological characteristics recognized for controlling air pollutants (15N and Pb) and also providing wildlife habitat for lac insects (Laccifer lacca) as well as providing nectar for honeybees. It is suggested that, given the contribution of tamarind trees to the environment, more and more of them should be planted as street tress, and to maintain it, the requirements of planting the trees should be taken into account.
