Abstract

   Hermetia illucens (L.), the black soldier fly (BSF), has raised attention due to its potential in solving various organic waste prob-lems and the benefits of the prepupa biomass as an alternative highly nutritious livestock feed. The availability of BSF populations strongly depends on mating success and reproduction. The mechanism of sex-ual selection during the mating period also determines the success rate of mating and reproduction and the survivorship of the offspring. Here, we analyzed how the influence of different mating status (virgin-ity) of mating pairs on mating success, daily oviposition, the number of eggs and fertility of eggs. BSF reared in semi-outdoor screen cages with five replication and four treatment of mates virginity combina-tion. An analysis of variance (ANOVA) was used to assess differences in mating and reproductive performance among treatment. Male and female BSF performed the remating activity. The virginity of males and females significantly influenced mating and oviposition frequen-cy. Mate choice was influenced by the virginity of mates. However, vir-ginity status of mates did not affect the number of eggs, eggs weight, and eggs fertility. Understanding of mate selection behavior in rela-tion to virginity in BSF served as important information to obtain the sustain population in the various scale of rearing design applicat

Abstract

 This study aimed to determine the response of the growth of sweet corn plants and weed density to the treatment of bio-fertilizer based on arbuscular mycorrhizal fungi and cow manure fertilizer. The study was conducted using a randomized complete block design (RCBD) in a factorial pattern. The first factor was arbuscular mycorrhiza fungi (AMF) consisting of four doses, namely without AMF (A0), AMF 5 g/planting hole (A1), AMF 10 g/planting hole (A2), AMF 15 g/ planting hole (A3). The second factor was cow manure fertilizer con-sisting of three doses, namely without cow manure fertilizer (B0), cow manure fertilizer 3 kg/plot (B1), cow manure fertilizer 6 kg/plot (B2). The treatment applied consisted of 12 combinations of treatments with 3 replications, so there were 36 experimental units. The observed variables were plant height, stem diameter, leaf area and weed density. The results showed that the average height of sweet corn was best at 42 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 111.6 cm. The average highest of stems diameter was at 14 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 0.40 cm. The average leaf area of sweet corn was at the age of 28 DAP was highest in the combination treatments cow manure fertilizer 6 kg/ plot (A0B2) and without AMF as 894.5. The weed species with the highest density found was I.cylindrica as 0.5-32.4%, C. kyllingia as 1.3-41.8%, C. rotundus as 1.3-30.3% and F.miliaceae as 1.2-12.7%.

Abstract

Diabetic wounds lead to severe tissue damage and are diffi-cult to cure. Jengkol (Archidendron pauciflorum) is a plant commonly used by local Indonesian communities to treat diabetic wounds. The efficiency of herbal medicine still has a deficiency of its ability to reach the target organs, therefore nanotechnology is applied in the hope that all drug concentrations can reach the target organs successfully. This study aimed to evaluate the effectiveness of PLGA nanoparticle ointment-ethanol extract jengkol fruit peel (EEJFP) to accelerate the wound healing process in the skin of streptozotocin-induced diabetic mice. The research method used was experimental with a completely randomized design using six treatments and four replications. Diabe-tes was induced by intraperitoneal injection of streptozotocin 180 mg/ kg BW. Mice with a blood glucose level of ≥150 mg/dL were used for diabetic mice models. The incision wound created at the dorsolateral region of shaven skin at ±1 cm2 using sterile scissors. The treatments given were vaseline for Control Negative (CN) and Control Positive (CP), Betadine ointment (PB), 10% EEJFP ointment (P1), 5% PLGA nanoparticle ointment-EEJFP (P2), and 2.5% PLGA nanoparticle ointment-EEJFP (P3). The results showed that the administration of PLGA nanoparticles ointment-EEJFP with a concentration of 5% PLGA nanoparticle ointment-EEJFP (P2) resulted in the shortest wound length on day 3, 7 and 14; narrower granulation tissue; a larger number of blood capillaries; and denser collagen fibers (α <0.05) compared to CP and PB treatments. The administration of PLGA nanoparticle ointment-EEJFP with a concentration of 5% was the most effective concentration in accelerating wound healing in the skin of diabetic mice.

Abstract

 Chicken meat and shrimp are perishable food materials. Giving natural preservatives is one way to extend the storage time of food. This study aimed to know the potential of papaya seed powder varieties of ‘Bangkok’ and ‘California’ as preservatives. The sample consisted of two varieties of papaya seed powder with concentrations of 2,4,6 and 8 g. Storage time for chicken meat and shrimp was the third days. Parameters measured were total bacterial colonies, pH va-lues, and organoleptic characteristics (color, aroma and texture) of fresh chicken meat and shrimp. The result showed papaya seed pow-der influences the quality of chicken meat and shrimp. fresh chicken meat and shrimp with papaya seed powder varieties ‘Bangkok’ and ‘California’ had a lower total bacterial colony as much as 9 x 105 until 1x106 compared to control which were 4.2 x 107 - 1.87 x 107. Organoleptic result of chicken meat and shrimp with the treatment of papaya seed powder and stored for three days continue to decrease in term of color, aroma and texture. In chicken meat, the decrease in bacterial growth was still within the limits of microorganism con-tamination quality in animal-based food. However, the same con-centrations of papaya seed powder in the shrimp have not been able to reduce bacterial growth until the limit permitted by SNI.

Abstract

Coffee fruit skin contains antioxidant compounds that can repair damaged tissues, especially those of reproductive or-gans. This study was designed to assess to what extent the metha-nolic extract of coffee fruit skin affected sperm characteristics and testicular histology in mice receiving 15% ethanol for 15 days. It used 25 male mice aged four months and employed a completely randomized design with two controls (K) and three treatments (P), namely K1 (without ethanol), K2 (15% ethanol), P1 (15% ethanol and the methanolic extract of coffee fruit skin, or MECS, at 125 mg/ kg BW), P2 (15% ethanol and MECS 250 mg/kg BW), and P3 (15% ethanol and MECS 500 mg/kg BW). These treatments were administered orally with a 1 mL disposable syringe for 15 days. The parameters observed were sperm characteristics (viability, morphology, and sperm count) and the microscopic structure of the testicles (lu-men area, diameter, and area of seminiferous tubules). These data were then analyzed using the one-way ANOVA, continued with the LSD and Duncan’s tests (P <0.05). The results showed that P2 (250 mg/kg BW) substantially improved sperm count (86.5x105±1.73 cells/ mL), sperm viability (87.26±0.05%), and the proportion of normal sperm morphology (93.33±0.004%) of mice with 15% ethanol-in-duced sperm damages. Testicular histology also confirmed improve-ments in spermatogenic cells, as evident from the lumen, diameter, and area seminiferous tubules after receiving P1 and P2. In conclu-sion, the optimum dose of the coffee skin extract for improving sperm quality and microscopic structures of mice testicles is 250 mg/kg BW.

Abstract

Snakes in Mekar Jaya mangrove ecosystem have the potential be ecotourism objects. On the other hand ecotourism activities might reduce the quality of wildlife habitat, including that of the snake. This study aimed to determine the diversity and status of snake species in the mangrove ecosystem of Rawa Mekar Jaya. A transect of 20 x 50 m was made in three stations: rivers (S1), ecotourism route (S2), and dense mangroves (S3). The observation was carried out at low tide and repeated three times with a span of 2 days. Snake data was collected using the Visual Encounter Survey (VES) method. We revealed 59 snakes in the mangrove area of Rawa Mekar Jaya consisting of 3 species namely Boiga dendrophila, Cerberus rynchops, and Trimeresurus purpureomaculatus. B. dendrophila and C. rhyncops are mangrove specialists. The Shannon Wiener diversity index value (H ') for all observation stations is below one, so it is classified as low. All types of snakes found are not protected and classified as the least concern. C. rynchops is included in the CITES appendix III

Abstract

Black soldier fly (BSF) (Hermetia illucens) is an insect spe-cies utilized as the converter of organic wastes into biomass applicable as a potential replacement of protein and lipid sources of animal feed and other industrial use. The limiting factor for the sus-tainability of this activity is the number of eggs produced as all processes started from the egg. Variable of quality of the substrate eaten during the larval stage and the proportion of males and fe-males are among the decisive factors for egg production. The pur-poses of this study were to understand the impact of the substrate to the production of a particular sex, to developed a simple method by comparing the weight and size of the pupae to distinguished between male and female, and to find the best sex ratio to produce the highest number of eggs. In this study, two types of substrates (balance proportion of macronutrient and high in protein and lipid were applied as feeding material for larvae. The weight and length of each pupa produced were measured and the pupae kept inside separated containers to find the morphological differences between male and female pupae. Adult insects produced from pupae then used for study on the effect of sex ratio on reproduction success. The adults kept inside 1 x 1 x 1 m screen cages with 3 groups of sex ratio (male : female) which were 50%:50% (P1), 60%:40% (P2), and 40%:60% (P3). The probability of sex was analyzed by logistic regression while the number of eggs estimated by the weight of the egg batch. The result showed substrate used in this study is not affect the sex ratio of adult flies, weight of pupae as the best predictor for sex of the adult flies, and the best ratio of male and female for egg production was 40:60.

Abstract

There are differences in the content of lactic acid, fat, pro-tein and carbohydrates in the curd kefir and colostrum kefir. The aims of this study were to determine the content of lactic acid, protein, fat, and carbohydrates of curd kefir and colostrum kefir based on the con-centration of starter and fermentation time. Experimental data were collected from a number of experiments at a temperature of 28°C. The method used was the experimental method of CRD 3 × 3 with 3 replications, the data were analyzed by analysis of variance. Good kefir contained high lactic acid, proteins, and carbohydrate and low in fat. The results showed curd kefir with the highest lactic acid con-tent of 1.59 % was at a starter concentration of 20% and a fermen-tation time of 72 hours (d2w3), the highest protein of 2.20% was at a starter concentration of 30% and a fermentation time of 72 hours (d3w3), the lowest fat of 1.16% found at a starter concentration of 30% and a fermentation time of 72 hours (d3w3), and the highest carbohydrate of 4.81% found at a starter concentration of 30% and a fermentation time of 72 hours (d3w3). Whereas in colostrum ke-fir with the highest lactic acid content of 2.83 % found at a starter concentration of 20% and a fermentation time of 72 hours (d2w3), the highest protein of 6.13 % was at a starter concentration of 10% and a fermentation time of 24 hours (d1w1), the lowest fat of 1.58% was at a starter concentration of 30% and fermentation time of 24 hours (d3w1) and the highest carbohydrate content of 17.91% was at a starter concentration of 30% and a fermentation time of 72 hours (d3w3). It can be concluded that the starter concentration and fer-mentation time have a significant effect (α <0.05) on lactic acid, pro-tein, fat, and carbohydrates content of curd kefir and kefir colostrum.

Abstract

Fruit flies (Bactrocera spp.) are an important pest for horticultural crops, especially fruits and vegetables. One of the most effective and eco-friendly methods to control male and female fruit flies is by usingtraps that use Methyl Eugenol (ME) block plus fruit essence as an attractant. The purposes of this research were to acquire the most effective formulation of ME Block plus fruit essence to catch the most male and female fruit flies on the chili plantation and to detremine the increase in total of fruit flies caught. This research started from December 2017 to January 2018 at Cibeureum Village, Sukamantri District, Ciamis Regency, West Java Province. The research was conducted using a randomized block design consisting of 8 treatments and 3 repetitions. The treatments consisted of adding fruit essence to the ME block: 2 ml of ME on cotton; 2 ml of ME block; 2 ml of ME block + 4 ml of mango essence; 2 ml of ME block + 4 ml of orange essence; 2 ml of ME block + 4 ml of guava essence; 2 ml of ME block + 4 ml of star fruit essence; 2 ml of ME block + 4 ml of chili essence; Antilat (Organic pesticide) as a comparison. The results showed that ME block plus fruit essence has increased the total of male fruit flies caught, but it did not attract female fruit flies. The best combinations with the highest average of male fruit flies caught were ME block plus orange essence with 750.67/5 week, followed by ME block plus chili essence with 746.00/5 week
