Abstract:
Generally, the standard procedure for karyotype analysis of shallot is sorted by chromosome sizes. Therefore, the identification of homologous chromosomes is difficult without using a specific probe. Nucleolus Organizing Regions (NORs) can be used as a probe for precise identification of homologous chromosomes. However, the use of NORs for plant karyotyping in Indonesia is poorly investigated. In this study, shallot chromosomes were prepared using modified Carnoy’s solution II, fixed in Carnoy’s solution, and stained by using aceto-carmine and AgNO3 for detecting NORs. Chromosome images were analyzed by CHIAS IV. One locus NOR bearing chromosome pair was detected at metaphase and interphase, and it was located at short arms of subtelomeric chromosome number 6. NORs can be used as a probe for precise identification of homologous chromosomes in shallot. Therefore, this technique has the potential to be applied on species closely related to shallot and on other plant species.Keywords: AgNO3, chromosome condensation, NORs, shallot chromosome, shallot karyotype ABSTRAKProsedur kariotipe untuk bawang merah umumnya masih disusun berdasarkan ukuran kromosom, sehingga diperlukan suatu penanda yang dapat mengidentifikasi kromosom homolog secara presisi. Identifikasi kromosom homolog secara presisi menggunakan suatu penanda, khususnya deteksi Nucleolus Organizing Regions (NORs), yang di Indonesia masih jarang dilakukan. Penelitian ini bertujuan untuk membuat kariotipe dan mengidentifikasi kromosom homolog bawang merah melalui deteksi NORs menggunakan metode pewarnaan AgNO3. Proses fiksasi akar dilakukan dengan menggunakan modifikasi larutan Carnoy II, lalu difiksasi dengan larutan Carnoy, dan kromosom diwarnai dengan aceto-carmine dan larutan AgNO3 untuk mendeteksi NORs. Selanjutnya, citra kromosom dianalisis menggunakan CHIAS IV. Hasil penelitian menunjukkan bahwa terdapat sepasang NORs yang terdeteksi pada fase metafase dan interfase yang terletak pada bagian lengan pendek di kromosom subtelosentrik nomor 6. Hasil dari penelitian ini dapat dijadikan sebagai dasar di bidang sitogenetika bawang merah untuk mengidentifikasi kromosom homolog secara presisi menggunakan penanda NOR. Oleh karenanya, teknik ini dapat diaplikasikan pada spesies yang berdekatan dengan bawang merah dan komoditas tanaman lainnya.Kata Kunci: AgNO3, kariotipe bawang, kondensasi kromosom, kromosom bawang, NORs

Abstract:
The Effects of Cereal Made From Sagu and Moringa oleifera on the Blood Glucose Level of Alloxan-Induced RatsDiabetes Mellitus (DM) type 2 could increase oxidative stress and blood glucose level. Resistant starch compounds in Cersa Mori have an antidiabetic properties.This research aimed to analyze the effect of Cersa Mori on fasting blood glucose (FBG) level of diabetic white rats induced by alloxan. This is a true experimental study with a randomized pre-post control group design using 27 male Wistar strain rats divided into 3 groups randomly, i.e (KN) feed and aquades, (KP) glibenclamide 0.126mg/200gBB/day, (P) Cersa Mori 5g/200gBB/day. KP and P groups were given alloxan 125 mg/KgBB subcutaneously and the intervention was carried out for 30 days. FBG level was measured using the GOD-PAP method. The results of Paired T-Test showed the effect of Cersa Mori on lowering FBG level in hyperglycemic rats (P=0,006). One-Way ANOVA test showed that Cersa Mori reduced FBG level, which was equalent to those given glibenclamide (P=0,366). It can be concluded that giving Cersa Mori 5g/200gBB/day for 30 days had a significant effect on lowering FBG level.

Abstract:
IDENTIFIKASI BAKTERI PATOGEN PENYEBAB PENYAKIT PURPLE SYNDROME PADA KARANG FUNGIA DI PULAU HARI SULAWESI TENGGARA Nowadays coral disease is one of the causes of damage to coral reefs in Indonesia. Causative agents were found for some types of coral disease. This study aims to identify the type of pathogenic bacteria that cause purple syndrome which attacks Fungia corals. The study was conducted using descriptive exploratory methods. Corals infected with purple syndrome were collected on Pulau Hari, Southeast Sulawesi, through scuba diving. Then, microbiological analysis was carried out which included isolation using the scatter method, purification using a scratch method, a challenge test (antagonistic), a Koch Postulate test, and DNA analysis of putative bacterial isolates. Results showed that 5 bacterial isolates lived in symbiosis with the corals infected with purple syndrome (PSMH1, PSMH2, PSMH3, PSMH4, and PSMH5). Based on the Koch postulate test, 2 bacterial isolates which were pathogenic were obtained, namely PSHM2 and PSHM4 isolates. These bacteria infected the test corals with the characteristics of coral skeleton damage and coral bleaching (dead). Based on biomolecular testing, the two isolates were members of Enterobacter cloacae with a 99% similarity level.Keywords: Coral disease; Enterobacter cloacae; Fungia coral; Hari island; Purple syndromeABSTRAKSaat ini penyakit karang menjadi salah satu penyebab kerusakan terumbu karang di Indonesia.

Abstract:
Pharmaceutical Grade Dextrose Monohydrate from Manihot ecsulenta, Metroxylon sagu, Zea mays, Oryza sativa, dan Triticum Starch ABSTRACT Pharmaceutical-grade dextrose monohydrate, one of raw materials used as active pharmaceutical ingredients (API) and additives, can be made from starch. There are five types of local Indonesian commercial starch that are potentially used, namely tapioca (Manihot esculenta), sago (Metroxylon sagu), corn (Zea mays), rice (Oryza sativa), and wheat (Triticum) starch. This study aimed to compare these five starches as raw materials for preparing pharmaceutical-grade dextrose monohydrate which was expected to meet the requirements of the Indonesian Pharmacopoeia (5th Edition) and the United States Pharmacopeia (USP). The starch was converted into dextrose monohydrate through liquefaction hydrolysis, saccharification hydrolysis, activated carbon purification and filtration, ion exchange purification, evaporation, crystallization and drying. High Performance Liquid Chromatogram (HPLC) and the Luff-Schoorl methods were used for dextrose equivalent value (DE) analysis. The results showed that only three of the starch types produced pharmaceutical-grade dextrose monohydrate, namely (DE) sago starch (107.23% and 100.77%), corn starch (97.86% and 96.19%), and tapioca starch (85.18% and 99.20%).Keywords: dextrose equivalent, dextrose monohydrate, hydrolysis, pharmaceutical grade, starchABSTRAKDekstrosa monohidrat kualitas farmasi, salah satu bahan baku yang digunakan sebagai active pharmaceutical ingredient (API) dan bahan tambahan, dapat dibuat dari bahan pati-patian.

Abstract:
Response Surface Optimization of Medium Fermentation for Streptomyces prasinopilosus as An Antifungal against Ganoderma boninenseGanoderma boninense is one of the pathogenic fungi that cause basal stem rot (BPB) on oil palm plants. This research aims to study the effect of carbon sources, nitrogen sources, and minerals on the production of Streptomyces prasinopilosus active compounds. Lactose, yeast extract, and minerals are medium components that show a real influence on the production of S. prasinopilosus active compounds. Optimization of the factors that have significant influence was predicted by the second-order model, statistically through a central composite design (CCD). The highest S. prasinopilosus active compound production, with a medium composition of 44.77 g L-1 lactose, 13.02 g L-1 yeast extract, and 15.95 mL L-1 mineral solution, was predicted by the quadratic model to reach 32269366.338 peak area unit on high-performance liquid chromatography (HPLC). The verification of the mathematical model of the production of the active compounds through experiments in the laboratory was 27,203,907.310 peak area unit. This result was 15.7% lower compared to the result of the quadratic model. Optimization increased S. prasinopilosus active compound 9-fold compared to that before optimization.Keywords: active compound; G. boninense; optimization; RSM; S. prasinopilosus ABSTRAKGanoderma boninense merupakan salah satu jamur patogen yang menyebabkan penyakit busuk pangkal batang atau biasa disebut BPB pada tanaman kelapa sawit.

Abstract:
Optimization of Western Blot Technique for Protein Expression of Rice Plant (Oryza sativa L.) Western blot (WB) technique has been widely used for analyzing protein expression and for identifying specific proteins derived from animals, plants, and microorganisms. During the use of WB, especially in agricultural studies, some difficulties are encountered such as unclear or unspecific protein bands, the presence of bubbles, and the absence of protein bands on membrane. This study aims to determine the WB conditions appropriate for the protein expression of rice plants (Oryza sativa L.). Protein from rice plant was extracted and the obtained protein lysate was then used for proteomic analysis using western blot with β-actin antibody. Our experiment showed that some optimized parameters like blocking buffers, the concentration of primary antibody and the ratio of secondary antibody determined the clarity of the results. β-actin was used as internal control that measured the success of the WB technique. Results showed that lysis process was important in determining good WB results in addition to the optimal blocking solution using a BSA of 0.2%, a primary antibody concentration of 1 μg mL–1, and a secondary antibody of 1:10,000. Optimizing techniques during extraction, incubation, and documentation facilitated good WB results.Keywords: β-actin; optimization; protein; rice plant; western blotABSTRAKTeknik western blot (WB) telah banyak digunakan untuk analisis ekspresi protein dan mengidentifikasi protein spesifik dari hewan, tumbuhan dan mikroorganisme. Dalam implementasi teknik WB, khususnya studi dalam bidang pertanian, beberapa kesulitan ditemui seperti pita protein tidak jelas, tidak spesifik, adanya gelembung, hingga tidak munculnya pita protein pada membran. Penelitian ini bertujuan untuk mengetahui kondisi WB yang tepat untuk deteksi protein tanaman padi (Oryza sativa L.). Protein tanaman padi diekstraksi, kemudian lysate protein yang didapat dianalisis dengan metode westernblot menggunakan antibody β-actin. Penelitian kami menunjukkan bahwa beberapa parameter yang dioptimasi seperti larutan blocking, konsentrasi antibodi primer dan rasio antibodi sekunder akan menentukan hasil yang jelas. β-actin digunakan sebagai kontrol internal yang menjadi tolok ukur keberhasilan teknik WB. Hasil menunjukkan bahwa proses lisis menjadi hal penting dalam menentukan hasil WB yang baik disamping larutan blocking yang optimal menggunakan BSA 0,2%, konsentrasi antibodi primer 1 µg mL–1 dan antibodi sekunder 1:10.000. Mengoptimalkan teknik selama ekstraksi, inkubasi dan dokumentasi membantu mendapatkan hasil WB yang baik.
