Judul: Potensi Larva Black Soldier Fly (Hermentia illucens) sebagai Campuran Formula Pakan Pengganti Trenggiling (Manis javanica)
Abstrak: Trenggiling jawa (Manis javanica) merupakan salah satu kekayaan fauna Indonesia yang harus dilestarikan. Salah satu faktor penting dalam konservasi ex situ adalah pakan. Pada pemeliharaan di kandang atau dalam penangkaran, trenggiling umumnya diberi pakan kroto atau kumpulan telur dan larva semut. Berbagai penelitian telah dilakukan bertujuan untuk mencari campuran pakan terbaik bagi trenggiling dengan biaya ekonomis. Larva Black Soldier Fly (BSF) yang dikenal dengan maggot merupakan bahan campuran pakan yang banyak digunakan di dunia peternakan karena memiliki kandungan protein dan lemak yang tinggi. Penelitian ini bertujuan untuk mengetahui potensi penambahan larva Black Soldier Fly (BSF) pada formula pakan pengganti trenggiling terhadap palatabilitas, tingkat kecernaan pakan, pertambahan bobot badan trenggiling, serta perhitungan biayanya. Formula pakan pengganti untuk empat ekor trenggiling terdiri dari 130 g kroto, 108 g maggot, 115 g telur rebus, dan 54 g pelet ikan koi serta tambahan suplemen berupa vitamin C, vitamin B kompleks, vitamin K, kalsium, dan asam formiat sebagai penambah aroma. Pakan diberikan sebanyak 2.5-3% bobot badan. Hasil penelitian memperlihatkan formula pakan dapat memenuhi kebutuhan dasar trenggiling dengan nilai kecernaan rata-rata 77.26% dan biaya pakan perhari sebanyak Rp37 275 harga ini lebih murah dari harga formula pakan pada penelitian sebelumnya. Hasil tersebut menunjukkan bahwa larva BSF bisa digunakan sebagai bahan campuran pakan trenggiling.

Judul: Test Palatability of Commercial Cat Feed with The Addition of Maggot Black Soldier Fly (Hermetia illucens) Protein Flour
Abstrak: Larva Black Soldier Fly (BSF) spesies Hermetia illucens memiliki kandungan nutrisi protein yang berpotensi menjadi alternatif sumber pakan hewan kesayangan yang ramah lingkungan, ketersediaan terpenuhi, serta komposisi nutrisi yang ideal. Namun, laporan penggunaan masih belum diketahui sebagai bahan pakan kucing. Uji palatabilitas pakan komersial dengan penambahan tepung protein maggot BSF bertujuan untuk mengetahui penerimaan pakan yang dikonsumsi. Uji palatabilitas dilakukan dengan metode monadik atau mangkuk tunggal pada kucing jantan domestik dengan dua tahap yaitu pemberian pakan adaptasi dan pemberian pakan uji pada empat kelompok perlakuan (0, 25%, 50%, dan 75%) dengan penambahan tepung maggot, yang masing-masing terdiri dari 3 ekor kucing. Hasil uji diperoleh dari jumlah konsumsi pakan harian dengan cara jumlah pakan yang diberikan dikurangi jumlah pakan sisa. Hasil penelitian menunjukkan tidak ada perbedaan nyata (P>0.05) pada perlakuan P1 sebesar 119±15.36 (g/h) dan 204±26.31 (kkal/h) pada jumlah konsumsi pakan dan jumlah kebutuhan kalori kucing harian. Berdasarkan hasil jumlah konsumsi pakan dan jumlah kebutuhan kalori maka dapat disimpulkan bahwa tepung protein maggot BSF dapat menjadi sumber bahan pakan kucing., Black soldier fly’s (BSF) larvae of Hermetia illucens species contain protein nutrients that have the potential to be an alternative source of pet feed which is environmentally friendly, sustainable, and has an ideal nutrition composition. However, the usage reports are still unknown as an ingredient in cat feed. The palatability test of commercial feed with the addition of maggot protein flour aims to determine the acceptability of the feed consumed. The palatability test was carried out by monadic method or single bowl on domestic male cats in two stages, feeding adaptation and giving test feed to four treatment groups (0. 25%, 50%, and 75%) with the addition of maggot flour, each of which consisted of 3 cats. The test results obtained from the amount of daily feed consumption by means of the amount of feed given minus the amount of leftover feed. The results showed that there was no significant difference (P>0.05) in P1 treatment of 119±15.36 (g/d) and 204±26.31 (kcal/d) in the amount of feed consumption and daily amount of cat needs. It can be concluded that BSF maggot protein flour can be a source of cat feed ingredients

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
