Abstract This study aims to obtain sucker weight and appropriate seedling site as a source of sago seeds by using seedling techniques in polybags to improve seed quality on sago cultivation. The experiment used a factorial design arranged in a randomized block design with three replications. Factor A, namely sucker weight, consisted of <999 g, 1000-1499 g, 1500-1999 g and > 2000 g. Factor B is the seedling site, consisting of laying seeds in the field, greenhouse and paranet of 60%. The results of the study showed that there was no interaction between the sucker weight combined with the seedling site, but the sucker weight had a significant effect on the number of rachis and the number of primary roots per plant and the percentage of life seedlings. Higher rachis growth was 3.8 obtained from medium-sized sucker weights (1000-1499 g and 1500-1999 g) and the highest number of primary roots was 41.3. It is obtained at sucker weights of 1000-1499 g. Meanwhile, the higher percentage of seedling survival was obtained at medium to large sucker weights of 66.3-71.0%. Thus, multiplication of sago seeds using medium-sized sucker on polybag media is highly suggested.

Rice is an essential food crop besides corn and soybeans. The need for rice each year increases along with population growth. One of the pests affecting rice is the white rice stem borer. The present research aimed to test the effectiveness and to examine the interaction between plant age and the number of Tricogramma japonicum parasitoid. The research was carried out at the Agrotechnology Laboratory of the Faculty of Agriculture, Khairun University, Ternate, and the rice fields of Bumi Restu village SP I, East Wasile district. The research design operative was a randomized block design where factor A (A1 = 21 DAS, A2 = 42 DAS, A3 = 56 DAS) was the age of the plant, and factor B (B0 = 0, B1 = 50, B2 = 100, B3 = 150) was the number of eggs of Corcyra cephalonica. Biological control using different amounts of Trichogramma japonicum parasitoid led to different interactions and results for each tested parameter. For the number of egg groups, there was no interaction with plant age, but the treatments which were found effective in suppressing stem borer populations were B2 and B3 (100 and 150). The most effective pias as indicated by damage intensity parameter was B3 (150), which was applied to plants aged 21 DAP. Furthermore, for plant height, different number of parasitoids poses significantly effective results. Percentage unhulled grain of pias B3 (150) causes insignificant damage. For production there is no interaction with plant age, but pias B2 (100) shows high yield. The conclusion is that pias B3 (150) applied to 21 days of plants is very effective in controlling white rice stem borer.

In order to confirm the dietary calcium (Ca) requirement to keep a balance of the production performance and the albumen transparency, the study examined the effects of different dietary Ca levels on the production performance, egg quality, and albumen transparency of laying pigeons. 1080 pigeon pairs were randomly allocated into six treatment groups, each consisting of six replicates of 30 pigeon pairs per treatment. Ca levels of 0.60, 0.90, 1.20, 1.80, 2.40, and 3.00% were fed. The results showed that the laying rate, average egg weight, and feed to egg ratio were significantly influenced by Ca levels (p < 0.05). Albumen percentage, albumen height, Haugh unit, and eggshell thickness at 8 w and 16 w were significantly influenced by Ca levels (p < 0.05). The L*, a*, b*, and c* values of cooked albumen at 8 w and 16 w were all significantly influenced by Ca levels (p < 0.05). After 16 w of feeding different Ca levels, the percentage of transparent eggs had an early increasing and later decreasing trend. In conclusion, taking the transparency of pigeon eggs as an assessment index and considering production performance secondly, the optimal level of dietary Ca for laying White King pigeons is 0.90%.

Shallot (Allium ascalonicum Linn.) is one of important commodities for Indonesian people, yet its production is still limited by pest attack This research was conducted in Banyuputih Village, Wringin Subdistrict, Bondowoso Regency from July to October 2019. This study applied a Randomized Block Design (RBD) with six treatments, namely: P1 = Polyculture of shallot + lemongrass; P2 = Polyculture of shallot + celery; P3 = Polyculture of shallot + mustard; P4 = Polyculture of shallot + lemongrass + mustard; P5 = Polyculture of shallot + celery + mustard; P6 = Monoculture of shallot. Each treatment was repeated 4 times. Observation was started when plant was at the age of 30 days after planting. Data collection was done by directly observing the sample plants. Sampling was carried out using Yellow trap and pit fall trap. A total of 10 samples were collected from each plot with interval of 4 days. Observation included collecting the pest insects and natural enemies that were found, counting the number of populations of each species, and scoring towards the damage plants. The results showed that shallot planting by polyculture with different types of plants affected the population of pests and natural enemies as well as the level of diversity of insects in shallots. Planting shallots by polyculture has been proven to control pest population compared to planting shallots by monoculture. Polyculture planting with two types of plants was found to produce better outcome than polyculture planting with three types of plants with best treatment observed in P1, namely polyculture of shallot and lemongrass which resulted in the lowest pest population of 17.5.

ABSTRAK. Fertilitas dan daya tetas sangat penting secara ekonomi untuk semua tempat penetasan, oleh karena itu harus diberikan perhatian khusus. Tujuan dari penelitian adalah untuk mengetahui pengaruh ukuran bobot telur terhadap persentase fertilitas dan daya tetas ayam Cemani dan White Leghorn. Telur tetas (299) dari ayam Cemani dan White Leghorn diperoleh dari kompleks kandang Balitnak dan dibagi menjadi 3 kategori ukuran bobot telur (kecil, sedang, dan besar). Data bobot telur tetas, fertilitas, dan daya tetas dianalisis berdasarkan Rancangan Acak Kelompok pola faktorial 3 x 2. Faktor pertama adalah ukuran bobot telur dan faktor kedua adalah jenis ternak, menggunakan prosedur General Linear Model dari SPSS versi 22. Jika terdapat pengaruh, maka diuji lanjut dengan uji Duncan. Sementara itu, untuk mengetahui hubungan antara ukuran bobot telur terhadap fertilitas dan daya tetas dihitung dengan persamaan regresi. Penelitian menunjukkan ukuran bobot telur secara signifikan (P0,05) memengaruhi bobot telur tetas, fertilitas, dan daya tetas. Telur ukuran sedang memberikan persentase fertilitas dan daya tetas yang lebih baik dibandingkan dengan telur ukuran kecil dan besar. Begitu juga untuk persamaan regresi memperlihatkan ada korelasi positif antara ukuran bobot telur terhadap fertilitas dan daya tetas, di mana ukuran bobot telur sedang mempunyai nilai R tertinggi. Pemilihan telur ukuran sedang akan bermanfaat untuk memaksimalkan persentase fertilitas dan daya tetas. (Percentage of fertility and hatchability of cemani and white leghorn chickens based on size of egg weight) ABSTRACT. Special attention to the trait of fertility and hatchability is very important because these two characteristics have economic value in all hatcheries. The purpose of this study was to determine the effect of egg weight size to the fertility and hatchability percentage in Cemani and White Leghorn chickens. The sample used in this research was the hatching eggs of Cemani and White Leghorn chickens (299 eggs) that obtained from the Balitnak chicken station. The eggs are divided into 3 egg weight size categories (small, medium and large). Data on weight of hatching egg, fertility, and hatchability were analyzed based on a 3 x 2 factorial randomized block design. The first factor was egg weight size and the second factor was breed. Data analysis used the General Linear Model procedure from SPSS version 22. If the effect is significantly different, then Duncan's test will be continued. Meanwhile, the correlation between size of egg weight and fertility is analyzed by regression. The results showed that the size of the egg weight was significantly (P0.05) on the hatching egg weight, fertility, and hatchability. The best percentage of fertility and hatchability is eggs in the medium category. Fertility and hatchability of eggs have a positive correlation with egg weight measurements, where the measurement of egg weight in the medium category has the highest R value. The choice of medium size eggs will be beneficial to maximize the percentage of fertility and hatchability.
