ABSTRACT Brazil is the second largest soybean producer in the world, with a yield of around 96.2 million tons per crop. This high yield leads to a great amount of waste resulting from soybean cultivation, which can reach approximately 41 million tons of waste per year. This material has lignocellulosic properties, which may enable its use as a raw material for particleboard production. Therefore, the objective of this study was to evaluate the use of soybean pods in particleboard production. For particleboard manufacture, wood of the hybrid Eucalyptus urophylla and Eucalyptus grandis was used, added with soybean pods, at proportions of 0%, 25%, 50%, 75% and 100%. For particleboard evaluation, a completely randomized design was used, with five treatments and three replicates, using linear regression and the Scott-Knott test at 5% significance for comparison among the different treatments. The properties apparent density, compaction ratio, water absorption after 2 and 24 hours, thickness swelling after 2 and 24 hours in water immersion, internal bonding, modulus of rupture and modulus of elasticity in bending properties were evaluated. The ratio soybean pod waste and eucalyptus particles in the panels led to an increase in water absorption values and thickness swelling, in addition to a decrease in mechanical properties. The production of panels with approximately 23% soybean pods is feasible.

Kepiting bakau (Scylla serrata) merupakan jenis golongan Crustaceae   yang mengandung protein hewani yang cukup tinggi dan memiliki nilai ekonomis yang tinggi. Ablasi mata merupakan salah satu cara untuk menghilangkan hambatan perkembangan telur (gonad) pada kepiting bakau. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) non factorial dengan 4 perlakuan dan 3 ulangan. Adapun perlakuan dalam penelitian ini adalah perlakuan A (ablasi satu pasang mata), perlakuan B (ablasi mata kiri), C (ablasi mata kanan), D (tanpa ablasi).   Hasil penelitian menunjukkan bahwa kecepatan kematangan gonad tertinggi pada perlakuan C (ablasi mata kanan) yaitu pertumbuhan gonad mencapai 21,53% dan terendah terjadi  D (tanpa ablasi)  pertumbuhan gonad hanya 14,8%. Analisa statistik dengan uji F menunjukan bahwa ablasi mata berpengaruh terhadap kecepatan kematangan gonad kepiting bakau. Pertambahan bobot tertinggi  terdapat pada perlakuan C (ablasi mata kanan) yaitu sebesar 2,67 gr kemudian disusul oleh D (tanpa ablasi)  sebesar 1,89 gr  dan terakhir  pada B (ablasi mata kiri) dengan nilai rata-rata sebesar 0,77 gr. Tingkat kelangsungan hidup terbaik terdapat pada perlakuan D (tanpa ablasi)   yaitu 100%, perlakuan B (ablasi mata kiri) 77,77%, perlakuan C (ablasi mata kanan) 66,66% dan kelansungan hidup terendah terjadi pada perlakuan A (ablasi satu pasang mata) 0%. Rata-rata kualitas air selama penelitian adalah suhu 27 0C dan Ph 7,65.Mangrove crab (Scylla serrata) have been classifying in Crustaceae clas that containing high animal protein and high economic value. Ablation of the eye is an solution to eliminate the egg development (gonads) barriers in the mangrove crab. The research design used a completely randomized design (CRD) non- factorial with 4 treatments and 3 replications. Treatment in this study were the treatment of A (ablation of the pairs of eyes), treatment B (left eye ablation), treatment C (right eye ablation), D (without ablation). The results showed that the highest rate of gonadal maturation was in treatment C (right eye ablation) where gonadal development growth reached 21.53 %, whereas the lowest was in treatment D (without ablation) where gonadal development growth was only 14.8 %. Statistical analysis by F test showed that ablation of the eye was affected the mud crab gonadal maturity. The Weight gain was found highest in the treatment C (right eye ablation) that reached 2.67 g and followed by treatment D (without ablation) 1.89 grams and the last in the treatment B (left eye ablation) with was an average value 0.77 grams.

One of the factors that caused the decline in cocoa production was the attack of cocoa pod borer. Black ants (Dolichoderus thoracicus) are known to be biological agents to control cocoa pod borer. This study aims to calculated the ability to prey on black ants in the cocoa pod borer larvae, the percentage of cocoa pod borer larvae that are eaten and to measured the potential of black ants as biological agents of cocoa pod borer. This research was conducted in Jaya Makmur Village, Nuhon District, Banggai Regency. The research used a completely randomized design consisted of 6 treatments and 3 replications, with each treatment as follows : P1 (20 larvae: 10 predators), P2 (20 larvae: 15 predators), P3 (20 larvae: 20 predators), P4 (20 larvae: 25 predators), P5 (20 larvae: 30 predators), and P6 (20 larvae : 35 predators). The results showed that the treatment of black ants on cocoa pod borer larvae (Conopomorpha cramerella) had a very significant effected on the cocoa pod borer larvae. The highest number of dead borer larvae was in the P6 treatment (20 larvae: 35 predators) two weeks after application with an average value of 16.3 then one week after application with an average value of 14.3. The highest percentage of borer larvae preyed on the P6 treatment was 81% at two weeks after application and 0.71% at one week after application.

The purpose of this research aims to determine the effect of adding enzymes (amylase, protease, xylanase) in feed on egg weight and egg yolk diameter in mixed ducks. The experimental animals used were 24 laying ducks. The design used was a completely randomized design (CRD) with 4 treatments and 6 replications. The four treatments were P0 (Control), P1 (6 ducks with Avizym1502®5gram / kg), P2 (6 ducks with Avizym1502® 10gram / kg), and P3 (6 ducks given Avizym1502). ® 15gram / kg). This treatment is carried out once a day for 9 weeks. Before the treatment, the ducks were adapted for a week. After that, the initial egg weight and yolk diameter were measured at week 0, week 6, and week 9. Data obtained from the results of weighing eggs found an average value of P0 (59.1667 ± 3.9200a) g, P1 5gram / kg (56.1667 ± 2.9268a) g, P2 10gram / kg (60.1667 ± 4.9966a) g, and P3 15gram / kg (67.6667 ± 2.7325ᵇ) g.

Seaweed Culture

Nusa Penida island is one of center for seaweed culture in Bali province. Seaweed that cultured is Euchema spinosum and Euchema cottoni spread around coastal. There also found wild seaweed, such as Ulva sp and Gracillaria sp. Abalone (H. squamata) is one of kind Mollusca which high economic value, but abalone cultured is not yet develop in Nusa Penida island, although this island have high potency for developing abalone culture. Abalone culture needs seaweeds as a diet. The abundance of seaweeds as abalon diet is important for developing abalon culture in Nusa Penida Island in the future. The aim of this research was to asses the potency of seaweeds as diet for developing abalone culture in Nusa Penida island. Research was done in Batununggul village, Nusa Penida Island. Experimental design was used Completely Randomized Design (CRD) with 3 treatments and 3 replications. The treatments were used different seaweeds as diet for abalone culture: (DG=Diet Gracillaria sp, DS=Diet Spinosum sp. and DU=Diet Ulva sp.). Abalon were cultured for 4 months by feeding the diet at satiation. Data analysis was used analysis varian (Anova) with SPSS. 16. The result showed abalon fed with Gracillaria sp (DG) at 4.73 g was the highest growth by 4.73 g, followed DU by 3.93 g and DS by 3.43 g. Meanwhile the abalon shell length fed with Gracillaria sp (DG) was the highest growth by 6.55 mm, followed DU by 5.97 mm and DS by 5.60 mm. Based on variant analysis showed growth performance (length shell and weight) abalon, all treatments were not significantly different (P>0.05). The conclusion this research, the three species of seaweed can be used as diet for abalone culture. These seaweeds have same potency as diet for developing abalone culture in Nusa Penida Island
