Judul: Performa Ayam Broiler dengan Penggunaan Tepung Maggot (Hermetia illucens) dalam Pakan.
Abstrak: Populasi ayam broiler terus mengalami peningkatan setiap tahunnya. Kendala pada peternakan ayam pedaging di Indonesia saat ini adalah bahan baku pakan yang masih impor. Maggot memiliki kandungan protein sebesar 43.42%. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan tepung maggot pada pakan terhadap performa ayam broiler. Penelitian ini menggunakan rancangan acak lengkap (RAL), dengan taraf perlakuan tepung maggot yang digunakan adalah R0 = 0%, R1 = 2.5%, R2 = 5%, dan R3 = 7.5%, dengan 5 ulangan dan masingmasing ulangan terdiri dari 10 ekor ayam. Peubah yang diamati adalah konsumsi pakan, bobot badan akhir, pertambahan bobot badan, konversi pakan, mortalitas, dan income over feed and chick cost (IOFCC). Hasil penelitian menunjukkan bahwa penggunaan tepung maggot berpengaruh sangat nyata (P<0.01) terhadap bobot badan, konsumsi pakan, pertambahan bobot badan, dan konversi pakan. Kesimpulan dari penelitian ini yaitu penggunaan tepung maggot dalam pakan dengan taraf 2.5%, 5%, dan 7.5% dapat menurunkan bobot badan, konsumsi pakan, pertambahan bobot badan, IOFCC, dan meningkatkan nilai konversi pakan serta mortalitas ayam broiler.

Judul: Sifat Fisikokimia Daging Ayam Broiler dengan Pemberian Pakan Tepung Maggot (Hermetia illucens).
Abstrak: Ayam broiler merupakan jenis ternak unggas yang memiliki pertumbuhan relatif cepat dengan umur panen 4-5 minggu. Komponen terpenting dalam pakan ayam broiler adalah protein. Sumber protein alternatif saat ini dibutuhkan untuk memenuhi kebutuhan ternak akan asam amino. Tepung maggot memiliki kandungan protein hingga 48% sehingga dapat dijadikan sebagai sumber protein pada pakan ayam broiler. Penelitian ini bertujuan untuk melihat pengaruh penggunaan tepung maggot terhadap sifat fisikokimia daging ayam broiler. Penelitian ini menggunakan rancangan acak lengkap (RAL), bahwa taraf perlakuan yang digunakan adalah R0 = 0%, R1 = 2.5%, R3 = 5%, dan R4 = 7.5%, dengan 5 ulangan. Parameter yang diamati adalah nilai pH, daya mengikat air, susut masak, keempukan, kadar air, kadar abu, kadar lemak, dan kadar protein. Hasil dari penelitian ini adalah daging ayam yang diuji memiliki DMA 35.80%-36.98%, pH 5.18-5.79, susut masak 37.32%-47.02%, keempukan 3.22-3.68, kadar air 73.85%- 76.12%, kadar abu 1.44%-1.62%, kadar lemak 0.33%-0.65%, dan kadar protein 20.18%-21.08%. Hasil penelitian menunjukkan penggunaan tepung maggot dengan taraf berbeda tidak memberikan pengaruh (P>0.05) terhadap DMA, keempukan, kadar abu, kadar lemak, dan kadar protein. Penelitian ini menunjukkan bahwa penggunaan tepung maggot tidak memengaruhi kualitas dari daging ayam broiler, sehingga dapat dijadikan sebagai sumber alternatif pakan ayam broiler.

Judul: Systematics of Desmos (Annonaceae) in Malesia
Abstrak: Desmos is a woody climbing genus of Annonaceae which has been widely used as traditional medicine in several countries such as China, Indo-China, Thailand, and Peninsular Malaysia to treat dysentery, vertigo, fever, and postpartum. Phylogenetic studies on Desmos showed a close relationship between Desmos and Dasymaschalon. They share similar moniliform monocarpic fruits, but their flowers are different. It has been debated among Annonaceae researchers whether both genera should be treated as the same or distinct genus. Therefore, investigation on the taxonomic delimitation of Desmos species and Dasymaschalon will be necessary. Plastid genome (plastome) identification, leaf epidermal section of Desmos species and Dasymaschalon species, a taxonomic revision of Desmos in Malesia using morphological data, the spatial distribution of Desmos species in Malesia, and morphological and genetic variation in Desmos chinensis population using ISSR marker were used to investigate taxonomic delimitation of Desmos. Plastome study of Desmos chinensis and Dasymaschalon dasymaschalum was carried out to determine the origin, evolution, phylogenomics, and identify marker candidates for Desmos and Dasymaschalon or with other genera in Annonaceae. We discovered that the plastome of Desmos chinensis was circular with the size of 167,677 bp (smaller than Dasymaschalon dasymaschalum), consist of 111 genes, including 78 protein-coding genes, 29 transfer RNAs, and 4 ribosomal RNAs. The plastome showed a typical quadripartite structure, i.e., large single copy (LSC), small single copy (SSC), and two inverted repeats (IRs). The plastome of Dasymaschalon dasymaschalum was 191,488 bp in length, which also exhibited a typical quadripartite structure (LSC, SSC, and two IRs). Desmos chinensis and Dasymaschalon dasymaschalum showed different copies of accD, ndhD, ndhF, rps18, and ycf2. Protein coding genes of rpoB, rpoC1, rbcL, matK, rpl32, infA, and rpl36 were identified based on nucleotide diversity, sequence variability, and parsimony-informative sites. The genes are defined as molecular marker candidates of plastome for phylogenetic, barcoding, and population genetic research. We predicted that Desmos chinensis and Dasymaschalon dasymaschalum separated at ca. 64 million years ago during the Paleocene. Leaf anatomical feature study was carried to support the taxonomic delimitation of interspecific Desmos and intergeneric of Desmos and Dasymaschalon. Leaf anatomy in the paradermal section of 20 taxa (12 species of Desmos, eight species of Dasymaschalon) have been carried out. According to the leaf epidermal section, Desmos and Dasymaschalon are two distinct genera mainly distinguished based on the anticlinal wall undulation of epidermal cells and supported by variation of the crystal type and size. The anticlinal wall undulation of Desmos was almost straight to slightly wavy and never sinuous; meanwhile, Dasymaschalon varies from almost straight to deeply sinusoid. The crystals of Desmos consist of rhombohedral, druse type A, and druse type B crystals, whereas Dasymaschalon has prism, druse type A, druse type B, and druse type C crystals. The recent taxonomic revision using the morphological data was mainly based on the examination of about 1374 specimens from BO, L, WAN, ANDA, SING, SAN, K, P, HUH herbaria. The Desmos species in Malesia consists of eight species: D. acutus, D. chinensis, D. chryseus, D. dunalii, D. pedunculosus, D. subbiglandulosus, two new records: D. lawii and D. macrocarpus, and one
