Abstract

Hydrophyte merupakan penggambaran habitat dari tumbuhan yang hidup di air baik terendam sebagian atau seluruhnya. Indonesia memiliki kekayaan jenis hydrophyte yang sangat tinggi, namun penelitian terkait inventarisasi belum dilakukan secara menyeluruh. Tujuan penelitian ini adalah untuk mengetahui kekayaan jenis hydrophyte air tawar yang ada di Sumatera Barat dan dikelompokkan berdasarkan life-form. Penelitian ini telah dilaksanakan pada November 2020 hingga Maret 2021. Metode yang digunakan adalah observasi dan data diperoleh menggunakan metode herbarium. Semua informasi pada label spesimen (occurence, taxon information dan event) diamati dan dicatat. Dari penelitian ini didapatkan 78 spesies dengan 54 genus dari 28 famili hydrophyte di Herbarium ANDA. Sebanyak 11 famili merupakan kelas Liliopsida dan 17 famili kelas Magnoliopsida. Berdasarkan life-form 2 jenis merupakan free-floating, 4 jenis floating-leaves, 7 jenis submersed dan 65 jenis lainnya merupakan emergent. Informasi penting secara konservasi pada penelitian yaitu ditemukan 4 spesies endemik dan 2 spesies new occurence. Tiga spesies endemik Sumatera, yaitu Apoballis okadae, Furtadoa sumatrensis (Araceae) dan Potamogeton sumatranus (Potamogetonaceae). Satu spesies endemik Sumatera Barat, yaitu Homalomena rusdii (Araceae). Taksa new occurence, Eleocharis acicularis (Cyperaceae) sebelumnya di Indonesia hanya ditemukan di Sumatera Utara, pada penelitian ini ditemukan di Sumatera Barat, Kabupaten Lima Puluh Kota. Heteranthera reniformis (Pontederiaceae) sebelumnya di Indonesia hanya ditemukan di Bogor, Jawa Barat, pada penelitian ini ditemukan di Kabupaten Tanah Datar, Sumatera Barat.

Abstract

Oil is used as an important component in human life as an energy source. The fried oil gives a delicious taste for consumption. However, the remaining cooking oil that has been cooked is discarded in the surrounding environment which is the cause of soil contamination by the oil. Thus, bioremediation is carried out to degrade contaminants with the ability of microorganisms or macroorganisms to become harmless compounds. The purpose of this research was to isolate and characterize the morphology of bacteria hydrocarbon-degrading from the environment or soil that had used cooking oil spills. The research method used was purposive sampling and descriptive qualitative. Purposive sampling is by determining where the sample to be taken has soil contaminated with used cooking oil and qualitative description is by describing the morphological characterization of the bacterial degrading isolates from the sample. The results of the research obtained that two bacterial isolates had a round shape, optically opaque, and flat edges. BCO-1 isolate has a brown color with a flat elevation and BCO-2 is white with a convex elevation. The bacteria degrading in BCO-1 isolates had a significant ability to degrade used cooking oil that was contaminated in the soil compared to BCO-2 isolates based on changes in the level of oil fluid.

Abstract

Industri kelapa sawit dapat menyebabkan dampak yang buruk bagi lingkungan terkait dengan limbah cair dari industri pengolahan maupun limbah padat dari perkebunan. Limbah padat dari perkebunan kelapa sawit, seperti pelepah sawit, sesungguhnya dapat dimanfaatkan ulang menjadi biochar yang digunakan sebagai bahan pelapis slow-release-fertilizer. Penelitian ini bertujuan untuk mempelajari pengaruh variasi komposisi, bahan pelapis, dan bahan perekat terhadap daya lepas nitrogen pada biochar-slow-release-fertilizer, serta mempelajari kinetika pelepasannya. Variasi yang digunakan adalah rasio biochar/bentonite 20%:80% – 80%:20%, jenis perekatnya asap cair dan minyak jarak, dan jumlah pupuk urea 30% massa total. Hasil penelitian menunjukan bahwa hasil optimum yang diperoleh untuk bahan perekat asap cair dan minyak jarak adalah berturut-turut pada rasio biochar/bentonite 50%:50% dan 60%:40%. Sedangkan hasil uji pelindian mendapatkan bahwa kedua formula tersebut mampu mempertahankan pelepasan nitrogen total hingga 28 hari, dibanding 13 hari untuk formulasi yang tidak dimodifikasi. Uji kinetika pelepasan menggunakan model Korsmeyer-Peppas menunjukkan bahwa mekanisme pelepasan kedua sampel tersebut mengikuti difusi Fickian.

Abstract

Several compounds that can boost immune activity (immunostimulatory) include vitamin E, curcumin, flavonoids, and vitamin C. In this study, ascorbic acid or vitamin C, was used as one method to enhance the immune system. This study aims to determine the immunostimulatory effect of vitamin C on the phagocytosis activity of macrophages in mice induced by Staphylococcus aureus. The mice were divided into two groups: the control group, which received 0.3 ml of distilled water orally, and the treatment group, which received 0.036 mg/g BW of vitamin C orally for 14 days. On the 15th day, each mouse was intraperitoneally induced with 0.5 mL of Staphylococcus aureus bacterial suspension and left for two hours. The phagocytic activity value represents the percentage of active macrophage cells among all macrophages observed. The result showed that the value of % phagocytic activity in the control group was 21.43% ± 7.92, whereas the % phagocytic activity in the treatment group was 48.31% ± 22.27. The group of mice given vitamin C 0.036 mg/g BW orally showed increased phagocytic activity compared to the control group mice. This shows that vitamin C has potential as an immunostimulator.

Abstract

Batik production in Indonesia is increasing from year to year. However, regarding environmental quality, it is feared that it will produce waste that pollutes the surrounding water bodies. This study aims to describe problems and solutions in improving the management of batik liquid waste in the city and district of Tasikmalaya (Cipedes and Sukaraja) using descriptive qualitative methods and the Miles and Huberman model. The results of the research using interview and observation methods show that most batik SMEs in these two areas have been unable to manage waste optimally. The problem arising from batik liquid waste is the contamination of residents' fish ponds, sewers, and bathtubs. Although there are three independent and communal WWTPs (Wastewater Treatment Plants) in Cipedes (MSME Agnessa, Deden, and riverbanks) as well as one independent WWTP in UMKM Sukapura "GJM," their utilization is still constrained by various natural and artificial factors. The role of the surrounding community is still low in understanding the existence and impact of batik waste around them.

Abstract

ABSTRAK Down Syndrome merupakan kelainan genetik autosomal karena kelebihan pada jumlah kromosom21 (Trisomi). Salah satu kekhasan pada penyandang down syndrome adalah mulut selalu terbuka, bibir memiliki celah dan relatif tebal. Tujuan dari penelitian ini adalah untuk menganalisis karakteristik pola sidik bibir pada penyandang down syndrome. Penelitian dilakukan pada bulan Desember 2021-Februari 2022 menggunakan metode wawancara dan pendataan langsung terhadap siswa penyandang down syndrome yang memenuhi syarat inklusi dari beberapa sekolah di Kota Bengkulu. Identifikasi pola sidik bibir mengacu pada klasifikasi menurut Suzuki dan Tsuchihashi. Data dianalisis menggunakan uji Chi-square pada program SPSS versi 22. Hasil penelitian menunjukkan bahwa pada siswa penyandang down syndrome ditemukan dua pola sidik bibir yaitu tipe I dan tipe II dengan pola dominan pada tipe I. Persentase pola sidik bibir tipe I pada siswa laki-laki sebesar 66,7% dan pada siswa perempuan 57,1%. Pola sidik bibir tipe II pada siswa laki-laki sebesar 33,3% dan pada siswa perempuan 42,9%. Berdasarkan hasil analisis menggunakan uji Chi-square, tidak terdapat hubungan antara pola sidik bibir dengan rasio tebal bibir dan panjang bibir, serta tidak terdapat hubungan antara pola sidik bibir dengan kemampuan berbicara, kemampuan berjalan, kemampuan menggenggam pena dan kemampuan menulis pada siswa penyandang down syndrome dari beberapa sekolah di kota Bengkulu. Pola sidik bibir dominan tipe I dan II yang ditemukan pada siswa penyandang down syndrome juga umum ditemukan pada non-down syndrome. Kata Kunci: Cheiloscopy, Down syndrome, Pola sidik bibir ABSTRACT An excess of chromosomal number 21 (Trisomy) causes the autosomal genetic disease known as down syndrome. One of the characteristics of people with down syndrome is that their lips have a gap and are rather thick, and their mouths are always open. This study's objective was to examine the characteristics of down syndrome students' lip print patterns. The study was carried out at multiple schools in Bengkulu City between December 2021 and February 2022 using interviews and direct data collecting on Down syndrome pupils with inclusion requirements. The classification of Suzuki and Tsuchihashi is used to identify lip print patterns. The Chi-square test was used to examine the data in SPSS version 22. Data were analyzed using the Chi-square test in the SPSS version 22. The findings indicated that students with Down syndrome had type I and type II lip print patterns, with type I predominating. Male students had a type I lip print pattern prevalence of 66.7%, compared to 57.1% for female students. 33.3% of male students have type II lip print patterns, compared to 42.9% of female students. According to the Chi-square analysis, there is no correlation between lip print patterns, the ratio of lip thickness to lip length, and speaking, walking, pen grasping, and writing abilities in down syndrome from various schools in Bengkulu city. Since the dominating lip print pattern of types I and II observed in down syndrome students is also frequently shown in non-down syndrome individuals, this pattern cannot be used to predict specific motor skills in down syndrome students. Keywords: Cheiloscopy, Down syndrome, Lip print patterns
