Abalon (Haliotisasinina) is a marine animal that is classified in shellfish and belongs to the class of gastrophoda, family haliotidae. It is one of the mainstays of NTB and national ethnofauna as marine commodities for export. The existence of these snails has provided an important role for the economy of coastal communities not only eaten or sold in the local market but also exported to several Asian countries, Europe and the United States. Thus, the growth of Abalone is very important to know quickly so that the process of abalone cultivation becomes more effective. Abalone growth is a logistical problems, Abalone growth can be observed through changes in weight, length and biomass. this study focused on the growth of abalone length as a continuation of previous research. The length of Abalone is also one of the parameters of successful cultivation and marketing. It should be noted that knowing the growth of Abalone is quiteslows so this also becomes an interesting phenomenon to study. Slow growth is certainly one of the economic problems because it is related to the time of marketing or harvesting. One way to know quickly the growth of abalone is to construct the mathematical modelso that based on the results of analyzing the model can be known the optimal length and time of harvesting. The mathematical model constructed in this case is the Von Berlatanffy model as a generalization of the Verhulst logistics model. Based on the results of analysis of the model obtained the growth of the length of the Abalone reaches a maximum of 12 cm at the age of 80 months. However, harvesting at that age is less effective because it will require more maintenance costs so that the optimal harvesting time is 26 months with an abalone length of 8 cm and the length is said to be the optimal length because it meets national or international market standards.Abalon (Haliotisasinina) is a marine animal that is classified in shellfish and belongs to the class of gastrophoda, family haliotidae.

This study aims to determine the effect of expired bread supplementation on sheep rations in digestibility and rumen fermentability in vitro. The study used a Compeletely Randomized Design (CRD) with 4 treatments and 3 replications. The first treatment P0 was a control, sheep fed with 100% basal concentrates. The second treatment P1, sheep fed with 95% basal concentrates plus 5% expired bread. The third treatment P2, sheep fed with 90% basal concentrates plus 10% expired bread. And the last treatment P3, sheep fed with 85% basal concentrates plus 15% expired bread. Data collected were rumen pH, concentration of NH3 (mM), digestibility of dry matter and organic matter (%). The result showed that feed treatments didn’t significantly affect (P>0.05) on rumen pH, concentration of NH3, digestibility of dry matter and organic matter. The average of rumen PH of treatment P0, P1, P2 and P3 respectively was 6.84; 6.86; 6.82 and 6.87. The average of concentration of NH3 of treatment P0, P1, P2 and P3 respectively was 16.17; 16.07; 13.52 and 16.62 mM. The average of dry matter digestibility of treatment P0, P1, P2 and P3 respectively was 51.76; 53.01; 52.16 and 54.71%. The average of organic matter digestibility of treatment P0, P1, P2 and P3 respectively was 53.16; 55.82; 52.24 and 57.59%. It was concluded that expired bread supplementation at the level of 15% can be used to replace basal concentrates in feed male local sheep.This study aims to determine the effect of expired bread supplementation on sheep rations in digestibility and rumen fermentability in vitro.

The article deals with the investigation of the homogenization process of high viscous liquid in a mixing tank. High viscous liquids are characterized by a high value of dynamics viscosity above value 10 Pa.s usually caused by Non- Newtonian behavior. There are lot of aspects that have a positive or negative effect on the homogenization efficiency, e.g. type of impellers, shape of vessel or spatial arrangement of the inserts in the vessel. The direction of the rotation of the proper impellers also affects the efficiency of the homogenization process. Correct high viscous liquid flow in mixing tank must be ensured by several specific types of impellers. The vertical direction of the liquid loop is recommended for homogenization process in cylindrical vessels. The simulations of the homogenization process of high viscous liquid in the cylindrical vessel have been performed. Two types of impellers were used. The axial pumping impellers were placed near the axis of vessel. The double-helical ribbon impeller ensured the liquid vertical movement near the wall. It has been found that the direction of the impeller rotation has a crucial effect on the homogenization effect, as expected. Simulations have been performed in ANSYS Fluent software. The liquid flow fields generated by clockwise (CW) and counter-clockwise (CCW) direction of the impeller’s rotation were investigated and compared.The article deals with the investigation of the homogenization process of high viscous liquid in a mixing tank.

Coral symbiont diversity is one of the most important factors in coral resistance and coral reef resilience to bleaching. Many corals host only one symbiont clade, thus many of them vulnerable to climate change induced bleaching. Corals in Alas Strait have survived from several bleaching events. The present study aimed to look at genetic factors that potentially contributed to the survival of Echinoporalamellosa coral. Previously, E. lamellosawas reported to host only one clade of symbiont, either in Pacific or Indian Oceans. Here we provide new evidence on the ability of E. lamellosain hosting multiple clades of symbionts. The symbiont rDNA was extracted from small E. lamellosafragments and amplified by targeting ‘the non-coding gene region’ of ITS1-5.8S-ITS2. The clustering technique was used to determine the clade type of symbiont, by constructing the phylogenetic tree consist of the sequenced samples and downloaded sequences from GenBank NCBI as comparison. The constructed phylogenetic tree was based on Maximum Likelihood (ML) with bootstrap value 1000× to get the best result. The result shows the symbiont in E. lamellosatissue belonged to clades B and C. The combination of the two symbiont clades has never been recorded in previous studies, and it is very likely to have contributed to coral survival from bleaching events.Coral symbiont diversity is one of the most important factors in coral resistance and coral reef resilience to bleaching.

The use of plants as traditional medicine is widely used in Indonesia society, especially in rural areas that still have plenty of plant varieties. The plants that have been used empirically and investigated to have potential efficacy as traditional medicine are MoringaoleiferaL.andCassia alata L. Leaves Extracts of Moringaoleifera L and Cassia alataL. contain several bioactive compounds and have high antioxidant activity. However, bioactive compounds of those leaves extract have low solubility in water. Hence, to be formulated into Self-Nanoemulsifying Drug Delivery System (SNEDDS) is one of the solutions to increase the extract solubility. SNEDDS formulation of the extracts is not only can increase solubility but also bioavailability of the extract, so effectiveness of therapy is improved. Results showed that SNEDDS of MoringaoleiferaL.and Cassia alataL.leaves Extracts that used corn oil as oil phase, tween 80 as surfactant, and propylene glycol as the co-surfactant provided nanoemulsion with good characteristics. Emulsification time of Moringaoleifera L. and Cassia alata L. SNEDDS in Artificial Gastric Fluid (AGF) media were from 17 to 48 seconds and from 7 to 19 seconds; % transmittance ranges were from 89.40 to 90.09% and from 84.85 to 88.30%; particles size in the optimum formula were 10.7 nm and 20.2 nm; polydisperse index values were 0.012 and 0.447; and zeta potential values were -5.0 mV and -3.9 mV respectively.

One of the potential food sources of the Indonesian people is soybeans. This is due to the protein content which reaches 40%. The demand of soybean in Indonesia increase exponentially year by year and domestic production is unable to fulfill it, therefore the fulfillment of soybean needs is done through imports. Some efforts made to increase soybean productivity include improving soil fertility. One effort to improve soil fertility and increase photosynthetic productivity in seeds is by adding phosphor and organic fertilizers. The indicator of increasing soybean crop production is derived from the amount of photosynthate accumulation in seeds. This study aims to investigate photosynthate accumulation and distribution on soybean crop (Anjasmoro variety, a well known soybean variety in Indonesia) at various dosages of phosphor and organic fertilizers during the vegetative and generative phase. The experiment was conducted in Sesela Village, West Lombok Regency, West Nusa Tenggara Province during the second dry season (August - November 2015). The experimental design was using a randomized block design with two factors. The first factor was phosphor with 4 dosage levels: 0 kg/ha, 36 kg/ha, 72 kg/ha and 108 kg/ha. The second factor was organic fertilizer with 4 dosage levels: 0 ton/ha, 2.5 tons/ha, 5 tons/ha and 7.5 tons/ha. Parameters observed were included nodule dry weight, root dry weight, stem dry weight and leaf dry weight. The results showed that the application of phosphor and organic fertilizers were not significantly affected the photosinthate accumulation and distribution on nodules, stems and leaves during the vegetative phase, however it was significantly affected the distribution of photosinthate on leaves during the generative phase. Application of phosphor 108 kg/ha and organic fertilizer 2.5 tons/ha gave highest dry matter accumulation on leaves at generative phase as well as highest N and P nutrient contents.One of the potential food sources of the Indonesian people is soybeans.

The economical value of horticultural product depends on the products freshness and its long lasting storage ability. These long lasting storage ability is depend on how we keep the fruits with their appropriate surrounding and also how we supplied the plants with exact dose of nutrient. It has been reported that brown macroalgae contains a lot of bioactive compounds including growth hormone and several kind of macro and micro nutrient which is potential to use as biofertilizer for tomato plant growth together with urea. Combination of these two fertilizers is expected to produce better quality and quantity of fruit. This article reported fruits in combination with longer shelf life quality and shelf age of tomato storage in soil applied with urea and brown macroalgae extract. Tomato plant were grown in soil media contained different dose of urea 0 gr for control (P0), 0.25 gr (P1) and 5 gr (P2). Each plant were also sprayed with 10% of Sargassum crassifolium (E1), Sargassum cristaefolium (E2), Sargassum aquifolium (E3) and Turbinaria murayana (E4). The result demonstrated that the tomato fruits produced by plants supplied with combination between urea and seaweed extract has better quantity of fruits (14-15fruit/plant) compared to control (9 fruits/plant). Fruit produce by plant supplied with 5 gr urea and S. cristaefolium extract has diameter of 2.7 cm which is bigger compared to the control and other treatment. Meanwhile, best fruit texture were 0.125 mm/g/5g (P1E3 and P2E2) in one month storage.

Brucea javanica (L) Merr, locally called “Wali”, is a plant traditionally used to treat diabetes mellitus by local people in Lombok. The people daily consumed the seed to control the blood glucose into normal level. However, the mechanism of action of Wali seed as antidiabetic agent was still unclear. Hence, in this study we investigate the proposed mechanism of action of Wali seed suspensed and ethanolic extract trough measuring the glycogen content in liver and muscles and observing the pancreatic histology of diabetic rats. Wali seed extract (dose 20 and 30 mg/kg BW) and suspense (25 and 50 mg/kg BW) have comparable antidiabetic activity with glibenclamide. Treatments of Wali seed extract and suspense showed dramatically higher glycogen level both in liver and muscles than all controls. Treatment with glibenclamide and Wali seed extract and suspense the pancreas to normal architecture, regeneration of β-cell and enhanced morphology of the β- cells in the islets of Langerhans. The proposed mechanism of action of Wali seed extract and suspense is by converting blood glucose to glycogen storage trough glycogenesis and by recovering the islets of Langerhans of pancreas damage.Brucea javanica (L) Merr, locally called “Wali”, is a plant traditionally used to treat diabetes mellitus by local people in Lombok.
