Abstract. An experiment was conducted to produce superior pigs with improved growth phenotypes and survival during postnatal growth by injecting the sows with gonadotropin prior to mating.Â The experiment consisted of 2 stages.Â In the first stage, 12 sows were divided into 2 groups i.e., sows injected with NaCl0.95% as a control (NSO) and sows injected with PG600 (SO) prior to mating.Â Parameters measured were growth phenotypes and survival at birth and during pre-weaning period.Â In the second stage, 24 of weaned pigs (age 8 weeks) from the first stage were selected (6 males and 6 females from NSO group and 6 males and 6 females from SO group) to be used for measurement of growth performance.Â The experimental pigs were raised and observed until the age of 28 weeks (7 month).Â The body weights were measured monthly.Â The results of the experiment showed that improvement of uterine environment by gonadotropin injection of the sows prior to mating dramatically improved birth weight with a very homogenous birth weight within litter size.Â Improved birth weight and within-litter variation of birth weight improved pre-weaning growth performance and survival that finally dramatically increased weaning weight and total weight of weaned pigs per sow.Â After weaning, pigs born to SO sows grew faster and had around 10 kg higher body weight as compared to control at the age of 7 month.Â Â It was concluded that superior pigs could be produced by improving endogenous secretion of pregnant hormone during pregnancy.Â Key words: Birth weight, growth phenotypes, survival, prenatal growth, postnatal growthÂ Abstrak. Penelitian ini dilakukan untuk menghasilkan anak-anak babi unggul dengan fenotipe pertumbuhan dan daya hidup yang lebih baik selama pertumbuhan pascalahir dengan cara menyuntik induk babi dengan gonadotropin sebelum pengawinan.Â Penelitian terdiri atas dua tahapan.Â Penelitian tahap pertama, 12 ekor induk babi dikelompokkan ke dalam 2 kelompok, 1) kelompok kontrol, yaitu induk yang disuntik dengan NaCl 0.95% (NSO) dan 2) kelompok yang disuntik dengan PG600 sebelum pengawinan (SO).Â Parameter yang diukur ialah fenotipe pertumbuhan dan daya hidup anak pada saat lahir dan selama periode prasapih.Â Tahap kedua, 24 anak babi lepas sapih dari percobaan tahap pertama (umur 8 minggu) dipilih (6 jantan dan 6 betinadari kelompok NSOdan 6 jantan dan 6 betina dari kelompok SO) untuk digunakan dalam pengukuran kinerja pertumbuhan pascasapih.Â Babi percobaan dibesarkan dan diamati sampai umur 28 minggu (7 bulan).Â Bobot badan diukur setiap bulan.Â Hasil penelitian menunjukkan bahwa perbaikan lingkungan uterus dengan cara penyuntikan induk dengan gonadotropin sebelum pengawinan secara dramatis memperbaiki bobot lahir anak dengan bobot lahir per induk yang lebih seragam.Â Perbaikan bobot lahir dan keseragaman bobot lahir memperbaiki kinerja pertumbuhan prasapih dan kelangsungan hidup anak yang pada akhirnya secara dramatis meningkatkan bobot sapih dan total bobot anak yang disapih per ekor induk.Â Setelah penyapihan, anak babi yang dilahirkan oleh induk yang disuntik gonadotropin tumbuh lebih cepat dengan bobot badan yang lebih tinggi sekitar 10 kg dibandingkan dengan kontrol pada umur 7 bulan.Â Disimpulkan bahwa anak babi unggul dapat dihasilkan melalui perbaikan sekresi endogen hormon kebuntingan selama kebuntingan.Â Kata kunci: Bobot lahir, fenotipe pertumbuhan, daya hidup, pertumbuhan prenatal, pertumbuhan pascalahir

An experiment was designed to study the growth phenotypes of piglets born to sows injected withpregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin (hCG) prior to mating inorder to improve endogenous secretions of pregnant hormones during pregnancy. The experimental sowsused in this study were 10 local breed sows with body weight ranges of 30-40 kg. Before mating, estrouscycles of the experimental sows were synchronized by injecting 3.75 mg prostaglandin twice with 14 daysinterval. The experimental sows were then divided into two groups, each consisted of 5 sows. The firstgroup was injected with 200 IU PMSG and 100 IU hCG per sow at the same time with the secondprostaglandin injection (day 15th), while the second group was not injected with PMSG and hCG but it wasinjected with NaCl 0.95% as a control. After showing estrous behavior, the experimental sows were mixedwith selected boars for natural mating. The pregnant sows were maintained until farrowing and weaning. Variable measured were body weights and body lengths and leg heights of the piglets at birth andweaning. The results showed that injection of the sows with PMSG and hCG prior to the mating, increasedbirth weight by 76.92% and total birth weight of live piglets per sow by 265.6% as compared to control.Piglets born to sows injected with PMSG and hCG prior to mating had higher survival rate with adramatically decreased mortality and a higher pre-weaning growth rate that finally increased total weightof weaned pigs per sows dramatically by 107.44% (increased 2 times) as compared to control. It is concludedthat the growth phenotypes of local piglets could be improved by injecting the sows with gonadotropinbefore mating.

Mujair fish (Oreochromis mossambicus) is a freshwater fish that is commonly consumed. This is due that they are easily found and obtrained and with a price in fresh markets that are relatively cheap. Unfortunately, this fish happens to be a very perishable commodity, due to it’s sensitiveness to spoilage because of its high protein content and moisture content. Pangi seeds (Pangium edule) is known to contain tanines, natural polyphenols that inhibits microorganisms through their cell wall permeability. The purpose of this research was to test the potential of pangi seeds crude extract as natural pangi seed toxiti preservatives on mujair fish, shelf life potential on mujair fish. This was achieved by marinating the fish in crude pangi seed extracts at concentrations of 0% (control), 5% and 10% and then store for 4 days at room temperature. Parameters tested on this research includes cyanide identification BSLT toxicity testing and fish spoilage (degradation) through protein changes and pH. Results of this research indicated that pangi seeds crude extract does not contain any cyanide of whatsoever, pangi seed crude extract toxicity testing indicated thatit was not toxic to a concentration of 128233mg/L, meanwhile protein analysis indicated that the optimum concentration of pangi seed crude extract to inhibit fish spoilage is 10% while in terms of pH degradation, the optimum concentration was 5%.

Perkembangan awal larva sangat dipengaruhi oleh ketersediaan makanan yang berasal dari kantung telurnya. Tidak terpenuhi nutrisi pada masa awal perkembangan dapat mempengaruhi perkembangan larva. Tujuan penelitian ini adalah untuk mengukur diameter telur hasil pemijahan Â dan panjang badan pada awal perkembangan larva ikan mas dari induk yang diberi pakan dengan penambahan kurkumin. Penelitian ini menggunakan induk betina ikan mas yang diberikan suplementasi kurkumin pada beberapa dosis yaitu 0%; 0,25%; 0,5%; 1%; dan 2%.Â Ikan yang telah matang gonad kemudian dipijahkan. Telur yang telah terbuahi kemudian diambil untuk ditetaskan dan diamati perkembangan larvanya selama 2 hari setelah penetasan (hsp). Hasil pengamatan menunjukkan bahwa perlakuan suplementasi kurkumin dengan dosis 0,5% yang diberikan dalam pakan induk betina ikan mas memberikan nilai yang optimal terhadap diameter telur hasil pemijahan (p<0,05) dan panjang badan larva sampai pada umur 2 hsp (p<0,05), namun panjang mutlak larva sampai pada 2 hsp tidak menunjukkan adanya perbedaan antar perlakuan (p>0,5). Berdasarkan hasil penelitian ini dapat disimpulkan bahwa suplementasi kurkumin dengan konsentrasi 0,5% pada induk betina ikan mas dapat mengoptimalkan pertumbuhan larva pada awal kehidupannya.Kata kunci : Cyprinus carpio; kurkumin; larvaÂ Early Development of Common Carp Larva from Broodstock Fed Diet Supplemented with CurcuminABSTRACTThe early growth of the larva is greatly influenced by the availability of food from the egg yolk. Insufficiency of nutrition in the early stages of development can affect the development of larva. The purpose of this study was to know the early growth of larva from broodstock supplemented with curcumin. This study used the female broodstock of common carp that supplemented with curcumin at several doses; 0%; 0,25%; 0,5%; 1%; and 2%. The fishes that had been mature were spawned, and the fertilized eggs were taken to be hatched. The larva was observed for 2 days after hatching (dah). The results showed that the treatment of curcumin supplementation with a dose of 0,5% given in the common carp feed gave an optimal value for egg diameter (p <0,05) and body length of the larva until the age of 2 dah (p <0,05), but did not differ for absolute length growth (p>0,05).Keywords: curcumin; Cyprinus carpio; larva

Feed is an important factor that influences the chicken's development and growth. Meanwhile, dalugha debris is a by-product of dalugha processing which is expected to be a source of feed for the growth and development of broiler chickens. The good feed can optimize metabolic processes in the animal so that it can support the process of growth and development of the animal. This study aims to determine the levels of hemoglobin, cholesterol, and blood glucose in broiler chicken that is given dalugha debris supplementation. This study used a completely randomized design (CRD), where as many as 60 docs of unsex chicken used were divided into four treatments and three replications. Each replication consisted of five chickens. The treatment given was the concentration of dalugha debris at several doses: 0%, 0.065%, 0.13%, and 0.26%. The parameters observed were hemoglobin, cholesterol, and blood glucose levels. The results showed that the provision of dalugha debris in the feed significantly (p<0.05) affected the blood glucose level, but did not affect the cholesterol and hemoglobin levels (p>0.05) of the broiler chicken.

The low student learning results may be observed in the value decided by the teacher, which is less than the KKM's average value of 75. The purpose of this study is to determine the impact of the mnemonic learning model on student biology learning outcomes in class XI MIPA SMA Negeri 4 Manado during the academic year 2021/2022. This study used a quasi-experimental design. This study's sample included two classes: class XI MIPA 1 as an experimental class with 20 students and class X1 MIPA 2 as a control class with 20 students. The results showed that the average pretest and post-test learning outcomes obtained by students in class XI MIPA 1 (experiment) with the application of the pretest mnemonic learning model were 34.75 and 76.75, respectively, while the pretest and post-test learning outcomes obtained by students in class XI IPA 2 (control) with only conventional learning were 31.25 and 71.25, respectively. The value of tcount> ttable was derived by hypothesis testing the pretest and post-test data in the experimental and control classes at a significant threshold of 0.05. The table value is 2.024, whereas the count value is 2.681. H0 is rejected based on the hypothesis testing criterion, but H1 is approved. This suggests that H0 has no effect, however H1 has an affect on student learning outcomes in Biology class XI at SMA Negeri 4 Manado.
