Abstract

Latar Belakang: Ubi kayu merupakan salah satu tanaman yang banyak ditanam hampir di seluruh wilayah di Indonesia dan menjadi sumber karbohidrat  dan sumber kalori yang cukup tinggi (161 Kkal), umbinya mengandung air sekitar 60%, pati (25-35%), protein, mineral, serat, kalsium, dan fosfat. Ubi kayu hitam merupakan jenis makanan tradisional masyarakat Banda yang memanfaatkan jenis ubi kayu pahit (Manihot aipi Phol) yang berkadar HCN tinggi, merupakan kearifan lokal  yang  perlu di kembangkan. Dimana ubi kayu  hitam ini akan di olah menjadi menu makan yang disebut dengan sunu-sunu.Metode: Tipe penelitian yang digunakan adalah penelitian eksperimen untuk menguji kandungan HCN  Metode Trimetrik. Penelitian ini dilaksanakan mulai dari tanggal 17 Juni sampai 17 Juli.Hasil: Penelitian ini ,menunjukkan bahwa hasil pengukusan  dengan pengulangan sebanyak 4 kali pada kadar HCN ubi kayu hitam, menunjukan bahwa perlakuan pengukusan 30 menit dan 1 jam menunjukkan setiap perlakuan 30 menit dengan memiliki rata-rata kadar HCN tertinggi sebesar  74,6 (mg/kg) sedangkan pada perlakuan 1 jam dengan pengulangan 4 kali memiliki rata-rata kadar HCN terendah, sebesar 63m4 (mg/kg).Kesimpulan: Rata-rata  kadar HCN ubi kayu hitam  pada waktu pengukusan  30 menit dan 1 jam yaitu 74,6 mg/kg dan 63,4 mg/kg,  kadar HCN ubi kayu hitam tertinggi pada waku 30 menit lebih tinggi dibandingkan kadar HCN pada waktu 1 jam

Abstract

The objective of this research is to assess the effects of sodium borat on concentration, motility, velocity of movement, and normal morphology of spermatozoa in rats. Fifty male rats at four months age were fed in five trearment groups per day,    i. e : (1) without treatment, (2) placebo of sodium borate ; 1 ml CMC 1%, (3) 200 mg sodium borate per kg body weight, (4) 400 mg sodium borate per kg body weight, and (5) 600 mg sodium borate per kg body weight. The concentration, motility velocity of movement and normal morphology of spermatozoa were research with modification of First method (1991) ; Suhadi and Arsyad method (1983). The result of this research showed that sodium borat decreased concentration, motility, velocity of movement and normal morphology of spermatozoa in rats.

Abstract

The low participation of men in Family Planning Program is caused by the limited choices of contraception for men. The purpose of this research is to find out the effects of secang woods extract on the spermatozoa viability of male mice, it is expected that some day secang wood could be formulated into components of oral contraception for male.        Thirty male mice weigh 25-30 g of 2,5 month old are grouped using Complete Random Design (RAL) factorial patterned 2x5 witn n=3. The extract of secang wood is made as ethanol extract, chloroform and water fraction each with 50 mg/25 g weight and given 1 ml orally each day. The analysis of the spermatozoa viability is conducted by supravital painting. The observation of preparation is done by 400x magnification. The living spermatozoa are colorless and the dead ones are red. The observation is conducted twice. Ten days after the extract is given (to identify the changes) and ten days after the extraααct is stopped (to see the recovery of spermatozoa). The gathered data is tested using Anava  (α   = 0,05) and DMRT   (α  = 0,05).  The result shows that the extract of secang wood can lower the viability of mice spermatozoa.

Abstract

Imperata grassland can be found in South Kalimantan in great amount and is known as a nuisance weed plants. The research is conducted to find out reed’s chemical content and its properties to know the description of the nature of the fiber as raw material for pulp and paper. The result of the research shows the water content of Imperata grassland is 97.76%, extractive content is 8.09%, the lignin content is 31.29%; 59.62% of holocellulose, 40.22% of alphacellulose, and 18.40% of pentosan. The second phase of the study of Imperata grassland fiber anatomy have been completed with the results of the fiber diameter is equal to 20 μm; 8.75 μm of lumen diameter, cell wall thickness is 5.65 μm and fiber length is 2.19 mm mm. Value of the derivative dimension of the Imperata grassland fiber obtained as follows: runkel ratio is 1.29; 42.24 (%) of mulstep number, power loom is 109.37, the valueof flexibility is 0.44 and stiffness coefficient is 0.28

Abstract

Bandotan (Ageratum conyzoides L.) is a plant belonging to the Asteracea family. This plant is widely used as medicine in various countries such as Africa, Asia and South America. Bandotan is used as medicine because it contains useful phytochemical compounds such as terpenoids, alkaloids, essential oils, saponins and phenolics. Some of the pharmalogical activities on bandotan include antibacterial, anti-inflammatory, antioxidant, and antidiabetic. Several studies have shown that bandotan can be used as a treatment for fever, rheumatism, headaches, stomach aches, medicine for pneumonia, drugs for diarhea, diabetes, and HIV/AIDS. The article review is expected to provide information about the use of bandotan as a traditional medicine or herbal medicine and its pharmacological activity.

Abstract

South Kalimantan province has huge natural resources Tanah Laut regency is one of the regencies in this province. This research is aimed to define the contents of Pb and Cd heavy metal in Crustaceae (shrimp and crab) of the Takisung and Batakan coasts in Tanah Laut regency, South Kalimantan.  Sampling was done twice with duplo method.  Pb and Cd content of the crustaceans was measured with AAS.  The result  showed a high contamination levels which were 42 – 125 ppm for Pb and 8 – 17 ppm for Cd, indicating that the contamination had exceeded the normal threshold (2 ppm for Pb and 1 ppm for Cd). It could be concluded that Takisung and Batakan Coast has been contaminated with heavy metals.

Abstract

The capability of Acetobacter xylinum to convert carbohidrate of rice-bran to cellulose was studied. Six treatments: 0, 1, 5, 10, and 20 g/L of rice-bran water were applied, and the thickness, weight and fiber from cellulose as fermentation results were recorded. It was discovered that higher concentration of rice-bran increased the thickness, weight and amount of fibers. Significant increase in fiber were found among 1 g/L, 5 g/L, and 10g/L of rice-brand. Higher concentration of rice-brand did not produced significant increase in fibers.
