Abstract

Abstrak Solanum merupakan salah satu marga terbesar pada kelompok tumbuhan Angiospermae. Marga tersebut terdiri dari 1400 jenis yang terdistribusi di kawasan tropis dan subtropis. Banyak anggotanya yang memiliki nilai ekonomi tinggi, sehingga telah dibudidayakan secara luas sebagai tanaman pangan, sayuran, tumbuhan obat, dan tanaman hias. Oleh sebab itu, beberapa di antaranya telah diintroduksi ke Pulau Jawa sejak lama. Sebanyak 24 jenis Solanum telah tercatat dalam buku Flora of Java vol. 2. Meskipun demikian, masih memungkinkan adanya jenis-jenis lain yang belum terekam dalam buku tersebut. Penelitian ini bertujuan untuk memberikan informasi mengenai jenis tambahan yang telah ternaturalisasi di Pulau Jawa. Pengamatan dilakukan di beberapa lokasi di Jawa Barat, Jawa Tengah, dan Jawa Timur pada tahun 2015 hingga 2017. Solanum diphyllum telah dikoleksi dari Bogor (Darmaga), Bandung (Taman Sari dan Pasir Impun), Sumedang (Jatinangor), Wonogiri (Desa Johunut), Semarang (Desa Mesu), Trenggalek (Desa Watulimo), Situbondo (Desa Wringin Anom dan Banyuputih), Bondowoso (Desa Bandilan), dan Sumenep (Desa Pakong). Jenis ini memiliki potensi untuk dimanfaatkan sebagai tumbuhan obat. Tumbuhan ini ditemukan tumbuh meliar di semua lokasi pengamatan dan keberadaannya perlu diperhatikan karena jenis tersebut merupakan tumbuhan asing invasif di kawasan lain.  Abstract Solanum is one of the largest genera in Angiospermae. This genus comprises about 1400 species distributed in tropic and subtropic regions. Some of them have high economic value and have been cultivated widely as crops, vegetables, medicinal plants, and ornamental plants. Therefore, several species have been introduced to Java island in the past. A total of 24 species of Solanum has been recorded in Flora of Java vol. 2. However, there is still unrecorded species occurred. The aim of this study was to provide information about an additional naturalized species in Java. The observations have been carried out in several locations in West Java, Central Java, and East Java, from 2015 to 2017. Solanum diphyllum has been collected from Bogor (Darmaga), Bandung (Taman Sari and Pasir Impun), Sumedang (Jatinangor), Wonogiri (Johunut Village), Semarang (Mesu Village), Trenggalek (Watulimo Village), Situbondo (Wringin Anom and Banyuputih Village), Bondowoso (Bandilan Village), and Pamekasan (Pakong Village). This species has a potential to be utilized as a medicinal plant. Moreover, this plant grows wildly in all of the observed locations. Its presence needs to be considered since it is known as an invasive alien species in other regions.  Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1.5448

Abstract

Abstrak Tujuan dari penelitian ini adalah untuk menentukan kondisi optimum fermentasi asam laktat pada beberapa perbandingan konsentrasi substrat dan inokulum yang berasal dari pemanfaatan limbah kulit pisang sebagai subtrat dan Lactobacillus casei sebagai inokulum. Optimasi dilakukan dengan rancangan percobaan menggunakan Central Composite Design (CCD) dengan penentuan titik optimum variabel menggunakan Respon Surface Methodolgy (RSM). Tiga belas satuan percobaan, yaitu konsentrasi substrat (X1: 2,5; 5; 7,5% b/v) dan inokulum (X2: 2, 4, 6% v/v), digunakan untuk menentukan titik optimum proses fermentasi. Fermentasi dilakukan dengan sistem tumpak dengan volume media 100 mL dalam fermentor berupa labu Erlenmeyer 250 mL. Kultur diinkubasi pada goyangan 150 rpm dan suhu 37 °C, selama 72 jam. Selanjutnya, asam laktat hasil analisis digunakan sebagai respon penentuan titik optimum variabel proses fermentasi. Hasil penelitian menunjukkan bahwa rendemen proses penepungan kulit pisang yang dihasilkan adalah 23,02% dengan karakteristik kimia memiliki kadar pati, gulatotal, asam total, dan serat kasar secara berturut-turut adalah 5,35; 1,36; 0,61; dan 1,54 % (b/b). Titik optimum konsentrasi substrat dan inokulum, yaitu 4,71% dan 6,61%, menghasilkan konsentrasi biomassa yang optimum sebesar 5,99 g/L, sedangkan titik optimum variabel X1 dan X2 dengan konsentrasi substrat dan inokulum sebesar 4,31% dan 4,64% menghasilkan nilai optimum konsentrasi asam laktat sebesar 7,06 g/L, yang merupakan hasil produksi asam laktat terbaik pada penelitian ini.   Abstract The objective of this study is to determine the optimum condition of lactic acid fermentation with various concentrations of substrate and inoculum, which derived from the utilization of banana peel waste as substrate and Lactobacillus casei as inoculum. Response surface methodology (RSM) was used in this study. Variable optimization was conducted by Central Composite Design (CDC) with RSM to determine the optimum point of lactic acid fermentation variable. Those step used 13 groups with independent variable in the form of substrate concentrations (X1:2.5; 5; 7.5% w/v) and inoculum concentrations (X2: 2, 4, 6% v/v) to decide the optimum point of variable in the fermentation process. Fermentation was performed in a batch system with 100 mL media in a fermenter of 250 mL Erlenmeyer flask. The culture was incubated at 150 rpm and 37 °C for 72 hours.The result of lactic acid was used to determine the optimum point of variable in fermentation. The results showed that the yield from the fluor making process of banana peel was 23.02% with chemical characteristics of starch content, total sugar, total acid, and crude fiber were 5.35; 1.36; 0.61; and 1.54% w/w, respectively. The optimum concentration of substrate and inoculum concentration, 4.71% and 6.61%, resulted in optimum biomass concentration of 5.99 g/L, while the optimum point of X1 and X2 variables with substrate and inoculum concentration of 4.31% and 4.64% yielded optimum lactate acid concentration of 7.06 g/L, which is the best production of lactic acid in this study.

Abstract

Abstrak Terung (Solanum melongena L.) tergolong tanaman yang sensitif terhadap kekeringan selama tahap pertumbuhan dan perkembangannya. Karakteristik stomata dan trikoma merupakan kriteria yang dapat digunakan untuk mengidentifikasi tanaman yang toleran terhadap kekeringan. Penelitian bertujuan menguji respons karakteristik anatomi daun berupa trikoma dan stomata tanaman terung terhadap cekaman kekeringan melalui empat taraf interval penyiraman. Penelitian menggunakan Rancangan Acak Lengkap melalui empat taraf interval penyiraman, yakni 3, 6, 9, dan 12 hari.  Pengaruh cekaman kekeringan terhadap morfologi permukaan daun pada terung menyebabkan terjadinya peningkatan kerapatan trikoma tiga kali lebih banyak dibandingkan dengan kontrol, penurunan ukuran lebar trikoma mencapai 59,02%, penurunan ukuran lebar stomata mencapai 78,34%, dan penurunan ukuran lebar porus stomata mencapai 80,80%. Hasil penelitian menunjukkan bahwa peningkatan jumlah trikoma dengan ukuran trikoma yang semakin kecil diduga sebagai bentuk proteksi tanaman terhadap kerusakan jaringan dan mekanisme adaptasi tanaman untuk dapat memenuhi jumlah asimilasi CO2 perluas daun yang dibutuhkan untuk fotosintesis pada kondisi kekeringan. Sensitifitas tanaman terhadap kondisi kekeringan berupa mekanisme adaptasi dengan cara memperkecil ukuran stomata dan bukaan lebar porus, sehingga laju fotosintesis tetap terjaga pada kondisi kekeringandan mekanisme tanaman menjaga efisiensi penggunaan air dengan cara mengurangi ukuran stomata dan memperkecil bukaan porus stomata.    Abstract Eggplant (Solanum melongena L.) belongs to a group of plants that are sensitive to drought (water stress) during their growth and development stages. Characteristics of stomata and trichomes are criteria that can be used to identify drought-tolerant plants. This study aims to determine the response of leaf anatomical characteristics of the eggplant as well as trichome and stomata to drought stress through four levels of watering interval. The research using completely randomized design with watering intervals of 3, 6, 9, and 12 days. The effect of drought stress on leaf surface morphology of the eggplant resulted in three times greater trichomes density than control, decreased trichomes width by 59.02%, stomata width by 73.84%, and size of stomata porch width by 80.80%.. The result was showing that increasing number of trichome with smaller trichome size was thought to be a form of crop protection against tissue damage and plant adaptation mechanism in order to meet the amount of CO2 leaf expansion assimilation required for photosynthesis in drought stress condition. The sensitivity of plants to drought stress conditions is the mechanism of adaptation by reducing the size of stomata and wide porous opening, so that the rate of photosynthesis has been maintaining in the dry conditions and the mechanism of the plant maintain the efficiency of water use by reducing the size of stomata and minimizing stomata porous opening.   Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1. 5667

Abstract

Abstrak Manggis (Garcinia mangostana L.) asal Bengkalis merupakan salah satu buah tropis yang menjadi komoditas ekspor Provinsi Riau dengan keunggulan dapat hidup di tanah gambut, tanah rawa, dan tanah masam. Pembentukan nodul tanaman manggis merupakan tahapan awal perbanyakan tunas pada kultur in vitro. Penelitian ini bertujuan untuk menentukan konsentrasi Benzilaminopurine (BAP) dan madu, baik tunggal maupun kombinasi, pada Woody Plant Medium (WPM) dalam pembentukan nodul dari eksplan biji manggis yang dibelah tiga secara membujur. Penelitian ini menggunakan Rancangan Acak Kelompok dengan menggunakan konsentrasi BAP 0, 5, dan 7 mg/L dan madu 0, 3, 6, dan 9 mL/L, baik tunggal maupun kombinasi. Hasil percobaan menunjukkan bahwa persentase pembentukan nodul paling tinggi (100%) diperoleh dari perlakuan 5 mg/L BAP. Perlakuan pemberian konsentrasi BAP dan madu, baik tunggal maupun kombinasi, pada media WPM, tidak mampu mempercepat waktu muncul nodul. Jumlah nodul terbanyak di 40 hari setelah tanam pada perlakuan 7 mg/L BAP yang disertai 3 mL/L madu adalah 25,0 nodul/biji.   Abstract Mangosteen (Garcinia mangostana L.) from Bengkalis in origin is one of the tropical fruit that became an export commodity of Riau Province, with the advantage of living in peat soil, swamp, and acidic soil. The formation of nodules is an early stage of shoot propagation in vitro cultures. This study aims to determine the concentration of BAP (Benzilaminopurine) and honey, either single or combination, in Woody Plant Medium (WPM) in the formation of nodules from mangosteen seed explants. This research employed Randomized Block Design to test the variation of BAP in the concentration of 0, 5, and 7 mg/L and honey in the concentration of 0, 3, 6, and 9 mL/L, either single or a combination. The results showed that the highest percentage of nodule formation (100%) was obtained from the treatment 5 mg/L of BAP. The treatment of BAP and honey, either single or combination, on WPM media, was unable to accelerate the timing of nodules. The highest number of nodules in 40 days after planting in the treatment of 7 mg/L of BAP with 3 mL/L of honey was 25.0 nodules/seed.  Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1.5422

Abstract

Abstrak Lumpur minyak bumi (oil sludge) memiliki kandungan kontaminan petroleum hidrokarbon terbesar, karenanya pengolahan limbah oil sludge perlu dilakukan agar tidak mencemari lingkungan. Penelitian yang menguji kemampuan jamur indigenus Riau (Penicillium sp. PN6) dan legum akuatik (Neptunia oleracea) dalam meremediasi senyawa hidrokarbon dengan pengukuran total petroleum hidrokarbon (TPH) pada limbah oil sludge telah dilakukan. Pertumbuhan N. oleracea dilakukan pada media limbah oil sludge dengan konsentrasi 25, 50, 75, dan 100%. Selanjutnya dilakukan pemberian inokulum Penicillium sp. PN6 ke dalam media pertumbuhan. Hasil penelitian menunjukkan bahwa persentase pertumbuhan N. oleracea adalah 95,58; 85,87; 25,55; dan 0%, berturut-turut pada limbah oil sludge 25, 50, 75, dan 100%. Terjadi penurunan konsentrasi TPH awal pada semua perlakuan di akhir pengamatan. Penicillium sp. PN6 meningkatkan degradasi TPH dari limbah oil sludge dibandingkan dengan kombinasi Penicillium sp. PN6 dengan N. oleracea, tetapi kombinasi Penicillium sp.PN6 dengan N. oleracea meningkatkan persentase penurunan TPH dari limbah oil sludge dibandingkan dengan menggunakan Penicillium sp. PN6 saja. Penicillium sp. PN6 dan kombinasinya dengan N. oleracea sama-sama mampu menurunkan pH limbah oil sludge.Abstract Oil sludge contains the largest contaminant of petroleum hydrocarbon that needs treatment to prevent its pollution into the environment. A study examining the ability of a Riau indigenous fungi (Penicillium sp. PN6) and an aquatic legume (Neptunia oleracea) to remediate hydrocarbon compounds by determining total petroleum hydrocarbon (TPH) in oil sludge waste has been conducted. The growth of N. oleracea was performed in the oil sludge waste media by concentrations of 25, 50, 75, and 100%. The medium was inoculated with Penicillium sp. PN6. The results showed that the percentage of growth of N. oleracea were 95.58; 85.87; 25.55; and 0%, in the oil sludge waste of 25, 50, 75, and 100%, respectively. There was a decrease in initial TPH concentration at all treatments at the end of the observation. Penicillium sp. PN6 increased more TPH degradation of the oil sludge waste compared to a combination of Penicillium sp. PN6 and N.oleracea, but the combination increased the decrease percentage of TPH compared to those that used Penicillium sp. PN6 only. Penicillium sp. PN6 and its combination with N. oleracea are both able to decrease pH of the oil sludge waste. Permalink/DOI: http://dx.doi.org/10.15408/kauniyah.v11i1. 6350

Abstract

Abstrak Bakteri ureolitik merupakan mikroorganisme yang memiliki kemampuan untuk menghasilkan urease yang dapat mengendapkan kalsium karbonat (kalsit). Bakteri ini berpotensi sebagai agen bioremediasi logam berat dan sebagai bahan konstruksi beton. Penelitian ini bertujuan untuk mengisolasi, mengkarakterisasi, dan menguji presipitasi kalsit bakteri ureolitik dari tanah lokal Riau. Hasil penelitian memperoleh 30 isolat bakteri yang berhasil diisolasi dari tanah tempat pembuangan akhir, dan setelah dilakukan pewarnaan Gram, 77% isolat merupakan bakteri Gram positif dan hanya 33% merupakan bakteri Gram negatif.  Hasil uji presipitasi menunjukkan bahwa isolat- isolat dengan kode sp. 32, sp. 9, dan sp. 20 mampu membentuk kalsium karbonat berturut-turut sebesar 0,129 g, 0,126 g, dan 0,105 g, setelah diinkubasi selama 7 hari pada medium cair yang diberi penambahan urea dan kalsium. Isolat-isolat bakteri tersebut memiliki hubungan kekerabatan yang dekat, yang ditandai dengan besarnya koefisien kekerabatannya, yaitu lebih dari 70%. Dengan demikian, bakteri-bakteri yang terisolasi dan teruji dalam  membentuk kalsium karbonat asal tanah lokal Riau berasal dari sekelompok bakteri, yang berpotensi untuk dikembangkan sebagai campuran beton.  Abstract Ureolytic bacteria are microorganisms that have the ability to produce urease that precipitates calcium carbonate (calcite). This bacteria has potential as an agent for bioremediation of heavy metal and as a concrete construction material. The aim of this research is concerning about isolation, characterization, and examination on calcite precipitate of the ureolytic bacteria from Riau local soil. The result showed that 30 isolates were isolated from landfill soil, and after Gram staining, 77% of the isolates are Gram-positive and only 33% are Gram-negative. The result of precipitation examination showed that the bacterial isolates sp. 32, sp. 9, and sp. 20 precipitated 0.129 g, 0.126 g and 0.105 g of calcium carbonate, respectively, after incubation for 7 days in broth medium added with urea and calcium. The bacterial isolates have a close relationship, which is characterized by the magnitude of the coefficient of more than 70%. Therefore, the isolated and tested bacteria having the ability to form calcium carbonate from local soil Riau derived from a group of bacteria, which has a potential to be developed as a mixture of concrete.
