Effect of Vitamin A and Magnesium Supplementation on Consumption and Digestibility of Dry Matter and Organic Matter in Lamb
A study to determine the effect of vitamin A and magnesium supplementation on Dry Matter Digestibility (DMD) and Organic Matter Digestibility (OMD) in lamb. The research was conducted experimentally using a Randomized Completely Block Design (RCBD) using 18 rams local aged 7 - 8 months with an average initial body weight of 20 kg ± 2.38 kg. The feed was given at 4% Dry Matter (DM) of body weight with a ratio of ammoniated rice straw and concentrate of 25%:75%. The treatments tested were T0 (control), T1 (25% ammoniated rice straw, 75% concentrate, plus 2000 IU of vitamin A), and T2 (25% ammoniated rice straw, 75% concentrate, plus 2000 IU of vitamin A, plus 1 gram of magnesium). The results of the variance of the analysis showed that the treatment of vitamin A and Magnesium administration had a real effect (p<0.05) on the digestibility of organic matter, while other variables were not accurate. The average digestibility of organic matter was T0 at 91.49%, T1 at 91.19%, and T2 at 92.24%. T2 was the treatment with the highest digestibility, with a difference of 2.75% from the control treatment. After the Randomized Completely Block Design (RCBD) and Variance of Analysis test, the next test used Honestly Significant Difference (HSD). Vitamin A and Magnesium supplementation affected the digestibility of organic matter by 2.75% higher than the control treatment.Penelitian untuk mengetahui pengaruh suplementasi vitamin A dan magnesium terhadap konsumsi dan kecernaan bahan kering, bahan organik pakan pada domba. Penelitian secara RAK menggunakan 18 ekor Domba Jantan (7 – 8 bulan) dengan bobot 20 kg ± 2,38 kg. Pakan diberikan 4% bahan kering dari bobot badan dengan imbangan jerami padi amoniasi (JPA) dan konsentrat (25%:75%). Perlakuan yang diberikan berupa P0 (kontrol), P1 (JPA 25%, konsentrat 75%, dan vitamin A 2000 IU), sedangkan P2 (JPA 25%, konsentrat 75%, dan vitamin A 2000 IU serta magnesium 1 gram). Hasil penelitian menggunakan ANAVA menunjukkan rata-rata KBK P0, P1, dan P2 sebesar 797,70 ± 86,69 gram/ekor/hari, 857,19 ± 83,96 gram/ekor/hari, dan 914,75 ± 113,62 gram/ekor/hari. Rata-rata KBO P0, P1, dan P2 sebesar 776,88 ± 68,93 gram/ekor/hari, 774,54 ± 77,11 gram/ekor/hari, dan 879,56 ± 106,80 gram/ekor/hari. Rata-rata KcBK P0, P1, dan P2 sebesar 88,54 ± 0,02%, 88,84 ± 0,01% dan 89,70 ± 0,01%. Rata-rata KcBO P0, P1, dan P2 sebesar 91,49 ± 1,17%, 91,19 ± 0,85%, dan 92,24 ± 1,02%. Uji Beda Nyata Jujur (BNJ) terdapat pada kecernaan bahan organik P2 dan P3 sebesar 1,05 berpengaruh nyata terhadap kecernaan bahan organik. Suplementasi vitamin A 2000 IU dan magnesium sebesar 1 gram mampu meningkatkan KcBO, tetapi tidak berpengaruh nyata pada KcBK, KBK, dan KB
PENGARUH PENGGUNAAN FLY ASH PADA KUAT TEKAN BETON GEOPOLIMER DENGAN AKTIVATOR NATRIUM HIDROKSIDA (NaOH) DAN NATRIUM SILIKAT (Na2SiO3)
The study aims to find out the impact of the use of fly ash on the compressive strength of geopolymer concrete when compared to normal concrete as well as to know the optimum strength of geopolymer concrete with specified variation of activator mixture. This study uses experimental method by mixing concrete with previous research as references. The specimens used a cylinder mold with a diameter of 10 cm and a height of 20 cm with a specimens age of 7, 14, and 28 days. The total specimens is 36 with the NaOH concentration used was 14 M. The comparative ratio of NaOH and Na2SiO3 for variation I is 1,0 : 0,5, variation II 1,0 : 1,0, variation III 1,0 : 1,5. Geopolymer concrete replaces 100% of the amount of cement in normal concrete with fly ash. Compressive strength value of geopolymer concrete for variation I : 4,883 MPa, variation II : 7,856 MPa and variation III : 10,403MPa and compressive strength value of normal concrete is, 36,943MPa. The compressive strength of geopolymer concrete when compared with compressive strength of normal concrete in this study decreased with 67,28% for 7 days, 72,22% for 14 days, and 71,84% for 28 days. The optimum compressive strength of geopolymer concrete from variation of the activator mixture specified is at variation III with compressive strength of 10,403 MPa

Pemberlakuan Sanksi Terhadap Pengabaian Pengelolaan Limbah B3 Medis Di Indonesia
The medical hazardous waste management has been regulated in Indonesian laws, but awareness of its management is still at the lowest level. This can be seen from the open dumping of The Medical waste, processing without a permit, waste burning processes that do not comply with quality standards, lack of processing services, storage of hazardous waste that is not stored in its area, storage areas that do not comply with standards, and termination of the use of incinerators because they do not have a permit. This research analyzes the sanctions for neglect of The Medical (Hazardous) waste management provisions. This research is normative juridical research using a descriptive qualitative approach. The research shows that (1) in the laws governing the management of medical hazardous waste, there are provisions for sanctions related to not managing medical hazardous waste properly which are given in stages starting from written warnings, government coercion, administrative fines, freezing of business licenses, revocation business licensing up to criminal sanctions as an ultimum remidium. In addition, (2) it is undeniable that there are several challenges that are quite complex in the management of medical hazardous waste until the management has not run optimally.Mekanisme pembuangan limbah B3 medis telah diakomodir dalam peraturan perundang-undang di Indonesia, namun kesadaran akan pengelolaannya sesuai tuntunan dari regulasi yang ada masih begitu minim. Hal ini dapat dilihat dari masih adanya pembuangan limbah B3 medis secara terbuka, pengolahan tanpa izin, proses pembakaran limbah yang tidak mematuhi standar mutu, kekurangan jasa pengolahan, penyimpanan limbah berbahaya yang disimpan tidak pada areanya, penimbunan limbah, tempat penyimpanan yang tidak mematuhi standar, dan penghentian pemanfaatan incinerator karena belum mempunyai izin dari KLHK. Penelitian ini menganalisis sanksi yang diterapkan terhadap ketidaksesuaian dalam pengelolaan limbah B3 medis. Metode penelitian yang digunakan adalah penelitian yuridis normatif yang menggunakan pendekatan kualitatif deksriptif. yang menganalisis data sekunder guna mendapatkan gambaran mengenai sanksi-sanksi yang dapat diterapkan terhadap pihak yang mengabaikan pengelolaan limbah B3 medis. Hasil penelitian menunjukkan bahwa (1) dalam peraturan perundang-undangan yang mengatur mengenai pengelolaan limbah B3 medis terdapat ketentuan sanksi terkait tidak dikelolanya limbah B3 medis dengan baik yang diberikan secara bertahap mulai dari teguran tertulis, paksaan pemerintah, denda
Dampak Hukum Pengakuan Terhadap Palestina Menurut Hukum Internasional
Palestine, a country that has received recognition from many nations, faces unique challenges in achieving equal standing with other countries. These challenges include the territory still under the control of Israel and Hamas, a population largely composed of Israeli citizens, and a government structure that is divided between two entities-Hamas and Fatah/PLO. Despite the explicit and de jure recognition from various countries, Palestine's inability to function as a subject of International Law in practice renders this recognition ineffective. On the other hand, Israel has experienced a significant impact from this recognition, notably in the form of damaged diplomatic relations with several countries.Palestina adalah sebuah negara yang sudah mendapatkan pengakuan dari banyak negara. Namun pengakuan tersebut belum dapat membuat Palestina berdiri sejajar dengan negara-negara lain karena berbagai sebab, seperti wilayah yang masih dikuasai oleh Israel dan Hamas, penduduk yang lebih banyak warga Israel, pemerintahan yang tidak jelas karena ada 2 pemerintahan yaitu Hamas dan Fatah/PLO. Jadi walaupun Palestina sudah mendapat pengakuan eksplisit dan de yure dari berbagai negara namun pengakuan itu tidak berdampak karena secara de facto Palestina belum dapat menjalankan peranannya sebagai subjek Hukum Internasional. Sebaliknya Israel mendapatkan dampak yang signifikan dari pengakuan tersebut berupa rusaknya hubungan diplomatic dengan beberapa negara
