This study aims to determine the success of pseudopregnancy induction with artificial copulation methods in local rabbits. In this study, 9 local female rabbits and 1 local male rabbit aged 1–1.5 years-old and 1.8–2.2 kg body weight were used, which were divided into three treatment groups (n= 3).

Therefore, effort is needed to improve the local chicken population for its potential as Broilers. One of the solutions is to crossbreed between Jawa super hens and Pelung roosters with faster growth than other local chickens. The crossbreed chicken (Supel chicken) is expected to have faster growth and the potential as Broilers with local characteristics. The purpose of this study is to evaluate growth, body morphometry, and the phenotype of Super pelung (SUPEL) chicken. Parameters measured were body weight, body morphometry, and phenotype of Supel chicken. The measurements of weight, color, morphometry, and proximate analysis were also conducted on Jawa super egg. The results showed that the weight of Supel chicken during Day Old Chicken (DOC) was 33.57 ± 2.44 g and reached 1,164.00 ± 98.20 g in 3 months. The phenotype of Supel chicken showed combination characteristics of the two broods. Meanwhile, the weight of the Jawa super chicken egg average of 43.15 ± 3.57 g.

Interaksi padi varietas Dendang dengan penambahan 300 mg dosis silika menghasilkan jumlah malai per rumpun dan produktivitas tertinggi. Jumlah anakan dan bobot kering tajuk berkorelasi positif terhadap jumlah malai per rumpun (R²= 0,85; R²= 0,81), persentase gabah isi (R²= 0,75; R²= 0,60), dan produktivitas (R²= 0,65; R²= 0,70). Padi varietas Dendang mampu tumbuh dan berproduksi lebih optimal pada kondisi salin dibandingkan padi varietas IPB 4S. Penambahan silika sebanyak 300 mg mampu memperbaiki beberapa karakter morfofisiologi dan hasil panen.AbstractThe use of tolerant varieties with the addition of silica nutrients is an effort to increase rice resistance to saline conditions, thus improving the crop yields. The objective of the study was to examine the relationship between morphophysiological characters and crop yields of two rice varieties under salinity stress with the addition of solid silica nutrients. The study applied a completely randomized factorial design. The first factor was rice of Dendang and IPB 4S varieties, and the second factor was the dosage of silica per kg of soil, namely 300 mg, 450 mg, and 600 mg. In terms of plant height, Dendang variety was lower than IPB 4S, however Dendang produced higher number of tillers, canopy dry weight, number of panicles, percentage of filled grain, and productivity. Interaction between Dendang variety and the addition of 300 mg silica nutrients resulted in the highest number of panicles and productivity. The number of tillers and canopy dry weight had a positive correlation to number of panicles (R²= 0.85; R²= 0.81), to percentage of filled grain (R²= 0.75; R²= 0.60), and to productivity (R²= 0.65; R²= 0.70). The rice of Dendang variety was able to grow and optimally produce yield compared to IPB 4S under saline conditions. The addition of 300 mg solid silica nutrients was able to improve several morphophysiological characters and crop yield.","PeriodicalId":31088,"journal":{"name":"AlKauniyah Jurnal Biologi","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89079012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dransf. is an endemic palm species originating from the island of Sumatra. The palm is one of the collections of the Bogor Botanic Gardens with seven collection numbers of N. gajah from Jambi and Riau. However, the reproduction information of the palm is still unknown until now. Information on the phenology of flowering is essential in conservation activities, especially its presence in nature and the production of seeds for reintroduction purposes. This study aims to determine the phases and timing of the flowering period and the factors that influence the flowering of N. gajah in the Bogor Botanic Gardens. This study was conducted on individuals at the phase of initiation of flowering. Flowering observation variables include the length of the period from flower buds to the anthesis phase until the flowers wither, and the fertilization process from young fruit to ripe. The flower and fruit of N. gajah were documented in each stage. The data recorded included flower and fruit development time for each phase and visiting insects. Data analysis was carried out descriptively to describe the process of flowering and fertilization that occurred. The results showed that the flower initiation phase took an average of 25.5 days, the anthesis phase took 6–7 days, the anthesis phase took 7–9 days, and the fruit formation and ripening phase took 100–120 days. Insects that are thought to act as pollinating insects for N. gajah include Trigona sp., Polyrachis sp., and Apis sp.AbstrakNenga gajah J.

Palem tersebut menjadi salah satu koleksi Kebun Raya Bogor dengan tujuh nomor koleksi N. gajah yang berasal dari Jambi dan Riau namun informasi reproduksi palem tersebut masih belum diketahui hingga kini. Informasi fenologi pembungaan tersebut sangat diperlukan dalam kegiatan konservasi, khususnya keberadaannya di alam dan produksi biji untuk tujuan reintroduksi. Penelitian ini bertujuan untuk mengetahui fase-fase dan waktu periode pembungaan dan mengetahui faktor-faktor yang memengaruhi pembungaan N. gajah di Kebun Raya Bogor. Penelitian ini dilakukan terhadap individu yang berada pada tahap inisiasi pembungaan. Variabel pengamatan pembungaan meliputi panjang periode dari kuncup bunga menuju fase antesissampai bunga layu dan proses pembuahan dari buah muda sampai masak. Perkembangan bunga dan buah N. gajah didokumentasikan pada setiap fase, data yang dicatat meliputi waktu perkembangan bunga dan buah untuk setiap fase, serta serangga pengunjung. Analisis data dilakukan secara deskriptif untuk menggambarkan proses pembungaan dan pembuahan yang terjadi. Hasil pengamatan menunjukkan bahwa fase inisiasi bunga membutuhkan waktu rata-rata 25,5 hari, menuju fase antesis membutuhkan waktu 6–7 hari, fase antesis membutuhkan waktu 7–9 hari, dan fase pembentukan dan pematangan buah membutuhkan waktu 100–120 hari.
