Abstract

ABSTRAKTanaman rosemary (Rosmarinus officinalis) digunakan oleh masyarakat lokal Desa Rolat Rayat Kabupaten Karo, Sumatera Utara untuk pengobatan tradisional, seperti mengatasi gangguan pencernaan, nyeri otot, dan infeksi kulit. Di alam rosemary memiliki kemampuan yang menonjol dalam bertahan dari serangan hama. Penelitian bertujuan untuk mengidentifikasi dan menganalisa senyawa metabolit sekunder yang terdapat pada daun dan akar tanaman rosemary yang diperoleh dari Desa Dolat Rayat, Sumatera Utara. Analisa senyawa metabolit sekunder dilaksanakan secara kualitatif dan menggunakan Gas Chromatography-Mass Spectrometry (GC-MS). Ekstrakrosemary diperoleh melalui maserasi, di mana sampel daun dan akar masing-masing direndam dalam pelarut etanol 96% selama 3 x 24 jam pada suhu kamar. Hasil penelitian menunjukkan bahwa daun rosemary mengandung flavonoid, tanin, dan alkaloid, sementara akarnya mengandung flavonoid, terpenoid, tanin, dan alkaloid. Analisa GC-MS mengidentifikasi senyawa terpenoid utama seperti 9-tetradecen-1-ol dan dodecanal pada kedua bagian tanaman, serta senyawa tambahan 3-cyclohexene-1-acetaldehyde dan cyclohexene,1-methyl-4-(1-m) pada akar. Penelitian ini memberikan wawasan penting mengenai potensi farmakologis rosemary yang dapat dimanfaatkan untuk pengembangan produk herbal, obat-obatan dan mendukung pertanian berkelanjutan. ABSTRACTThe rosemary plant (Rosmarinus officinalis) is used by the local community of Rolat Rayat Village, Karo Regency, North Sumatra for traditional medicine, such as treating digestive disorders, muscle pain and skin infections. In nature, rosemary has a prominent ability to defend against pest attacks. The research aims to identify and analyze secondary metabolite compounds found in the leaves and roots of rosemary plants obtained from Dolat Rayat Village, North Sumatra. Analysis of secondary metabolite compounds was carried out qualitatively and used Gas Chromatography-Mass Spectrometry (GC-MS). Extract of rosemary was obtained through maceration, where each leaf and root sample was soaked in 96% ethanol solvent for 3 x 24 hours at room temperature. Research results showed that rosemary leaves contain flavonoids, tannins and alkaloids, while the roots contain flavonoids, terpenoids, tannins and alkaloids. GC-MS analysis identified the main terpenoid compounds such as 9-tetradecen-1-ol and dodecanal in both plant parts, as well as additional compounds 3-cyclohexene-1-acetaldehyde and cyclohexene,1-methyl-4-(1-m) in the roots. This research provided important insights into the pharmacological potential of rosemary which can be utilized for the development of herbal products, medicines and supporting sustainable agriculture.

Abstract

ABSTRAKInsektisida kimia sintetis masih banyak digunakan kalangan petani untuk mengendalikan hama ulat grayak (Spodoptera frugiperda J.E Smith) yang menyerang tanaman jagung. Penggunaan insektisida kimia secara berlebihan menimbulkan pengaruh negatif bagi lingkungan dan kesehatan. Alternatif pengendalian S. frugiperda yang ramah lingkungan perlu dilakukan dengan memanfaatkan jamur entomopatogen, salah satunya berasal dari spesies Beauveria bassiana. Penelitian ini dilakukan untuk mengetahui tingkat kerapatan spora B. bassiana dan waktu aplikasi yang efektif terhadap mortalitas S. frugiperda pada tanaman jagung. Penelitian disusun secara rancangan acak lengkap (RAL) faktorial. Faktor pertama berupa kerapatan spora (106, 107, 108, dan 109 spora/ml), akuades steril dan insektisida kimia sintetis deltametrin sebagai kontrol. Faktor kedua adalah waktu aplikasi jamur (pagi dan sore hari). Hasil penelitian menunjukkan aplikasi B. bassiana pada waktu sore hari dengan kerapatan 108 dan 109 spora/ml mengakibatkan mortalitas larva S. frugiperda sebesar 60% dan 73.3%. Waktu aplikasi B. bassiana pada sore hari mengakibatkan persentase mortalitas lebih tinggi dibanding pada pagi hari. ABSTRACTSynthetic chemical insecticides are still widely used by farmers to control armyworm pests (Spodoptera frugiperda J.E Smith) which attack corn plants. Excessive use of chemical insecticides has negative effects on the environment and health. Environmentally friendly alternative control of S. frugiperda needs to be done by utilizing entomopathogenic fungi, one of which comes from the Beauveria bassiana species. This research was conducted to determine the density level of B. bassiana spores and the effective application time for S. frugiperda mortality on corn plants. The research was structured in a factorial Completely Randomized Design (CRD). The first factor was spore density (106, 107, 108, and 109 spores/ml), sterile distilled water and the synthetic chemical insecticide deltamethrin as a control. The second factor was the time of fungal application (morning and evening). The results show that application of B. bassiana in the afternoon with a density of 108 and 109 spores/ml resulted in S. frugiperda larvae mortality of 60% and 73.3%. The application time of B. bassiana in the afternoon resulted in a higher mortality percentage than in the morning.

Abstract

ABSTRAK Lalat buah merupakan hama utama tanaman belimbing. Atraktan tanaman aromatik merupakan salah satu pengendalian yang ramah lingkungan. Jenis tanaman yang dapat dijadikan atraktan adalah pala dan kemangi. Metil eugenol pada minyak atsiri tanaman menghasilkan aroma feromon seks yang mirip dengan lalat buah betina sehingga menurunkan laju reproduksinya. Penelitian menggunakan rancangan acak lengkap dengan 5 perlakuan dan 4 ulangan. Pengumpulan data dilakukan dengan deteksi varian, jika terdapat perbedaan nyata maka dilanjutkan uji BNJ pada taraf 5%. Korelasi antara faktor abiotik dan populasi lalat buah juga diamati. Atraktan yang paling sering menangkap lalat buah adalah minyak atsiri pala. Korelasi suhu dan jumlah populasi lalat buah Y= 30.275 – 0.001x; R²=0.602 dan korelasi curah hujan dengan populasi lalat buah Y= -14.457 + 0.013x; R²=0.081. Kedua korelasi tersebut sama-sama tidak berpengaruh nyata. Semua lalat buah yang tertangkap adalah lalat buah jantan dari spesies B. carambole. Minyak atsiri pala mampu menangkap lalat buah lebih banyak yaitu sebanyak 262.5-344.7 ekor dibandingkan minyak atsiri kemangi sebanyak 35.6-39.7 ekor. Minyak atsiri pala memiliki masa aktif lebih dari 7 hari sedangkan kemangi hanya memiliki masa aktif 4 hari. ABSTRACT Fruit flies are the main pest of star fruit plants. Aromatic plant attractants are an environmentally friendly control agent. Types of plants that can be used as attractants are nutmeg and basil. Methyl eugenol in the plant's essential oil produces a sex pheromone aroma similar to that of female fruit flies, thereby reducing their reproductive rate. The study used a completely randomized design with 5 treatments and 4 replications. Data collection was carried out by variant detection, and if there were real differences then the BNJ test was continued at the 5% level. Correlations between abiotic factors and fruit fly populations were also observed. The attractant that most often catches fruit flies was nutmeg essential oil. Correlation between temperature and fruit fly population size was Y= 30.275 – 0.001x; R²=0.602 and correlation between rainfall and fruit fly population was Y= -14.457 + 0.013x; R²=0.081. Both correlations had no real effect. All fruit flies caught were male fruit flies of the species B. carambole. Nutmeg essential oil was able to catch more fruit flies, namely 262.5-344.7 compared to 35.6-39.7 basil essential oil. Nutmeg essential oil had an active period of more than 7 days, while basil only had an active period of 4 days.

Abstract

ABSTRAKJagung manis banyak digemari sebab mempunyai rasa lebih manis, beraroma lebih harum dan bergizi lebih tinggi. Pemupukan yang dilakukan petani selama ini terlalu banyak menggunakan pupuk anorganik yang tidak sesuai dosis. Metode ini tidak efektif dan mengganggu keseimbangan sifat-sifat tanah sehingga menurunkan produktivitas tanaman dan menghasilkan residu yang berbahaya bagi ekosistem. Untuk mengurangi ketergantungan pada pupuk anorganik perlu pengaplikasian pupuk organik. Penelitian menggunakan rancangan acak kelompok (RAK) faktorial. Faktor pertama yaitu dosis pupuk NPK (N) dengan taraf 5 g/tanaman, 10 g/tanaman dan 15 g/tanaman. Faktor kedua yaitu dosis POC urin kelinci dengan taraf yaitu 150 ml/tanaman, 225 ml/tanaman dan 300 ml/tanaman. Kontrol dibuat dengan pemberian pupuk NPK 100% tanpa POC urin kelinci. Hasil penelitian menunjukkan bahwasa tidak terdapat interaksi antara kombinasi perlakuan dosis pupuk NPK dengan POC urin kelinci terhadap semua parameter pengamatan. Masing-masing perlakuan dosis pupuk NPK 15 g/tanaman maupun faktor tunggal pada perlakuan dosis POC urin kelinci 300 ml/tanaman pada tanaman jagung manis memberikan hasil tertinggi pada parameter jumlah daun, panjang tanaman, diameter batang, bobot tongkol tanpa kelobot dan diameter tongkol. Tetapi semua perlakuan tersebut belum dapat menyamai hasil yang diperoleh perlakuan kontrol dosis pupuk NPK 20 g/tanaman (dosis anjuran 100%).  ABSTRACTSweet corn is popular because it has a sweeter taste, has a more fragrant aroma and more nutritious. Fertilization carried out by farmers so far uses too much inorganic fertilizer which is not in the appropriate dosage. This method is ineffective and disrupts the balance of soil properties, thereby reducing plant productivity and producing residues that are harmful to the ecosystem. To reduce dependence on inorganic fertilizers, it is necessary to apply organic fertilizers. The research used a factorial randomized block design (RAK). The first factor was the dose of NPK (N) fertilizer with levels of 5 g/plant, 10 g/plant and 15 g/plant. The second factor was the dose of rabbit urine POC with levels namely 150 ml/plant, 225 ml/plant and 300 ml/plant. Controls were made by recommended 100% NPK fertilizer without rabbit urine POC. The results of the study showed that there was no interaction between the combination of treatment doses of NPK fertilizer and rabbit urine POC on all observed parameters. Each treatment with an NPK fertilizer dose of 15 g/plant and the single factor treatment with a rabbit urine POC dose of 300 ml/plant on sweet corn plants gave the highest results in the parameters of number of leaves, plant length, stem diameter, cob weight without husk and cob diameter. However, all these treatments were not able to match the results obtained by the control treatment with an NPK fertilizer dose of 20 g/plant (100% recommended dose).

Abstract

ABSTRAK           Unsur iklim erat hubungannya dengan cuaca yang dapat menurunkan suatu usaha budidaya. Salah satu unsur iklim yang berpengaruh terhadap pertumbuhan dan produktivitas tanaman yaitu angin. Kecepatan angin memegang peran penting dalam evapotranspirasi, karena sebanding dengan evapotranspirasi. Data evapotranspirasi digunakan untuk kepentingan sumber daya air dan menghitung kesetimbangan air khususnya keperluan penentuan kebutuhan air bagi tanaman dalam periode pertumbuhan dan produksi tanaman sorgum. Penelitian ini bertujuan untuk menentukan bagaimana kecepatan angin dan evapotranspirasi mempengaruhi pertumbuhan dan produksi tanaman sorgum. Penelitian dilakukan di lapangan percobaan Stasiun Klimatologi BMKG Aceh, Aceh Besar. Metode penelitian yang digunakan meliputi analisa regresi linier berganda, uji T, uji F, koefisien korelasi dan koefisien determinasi. Parameter penelitian meliputi tinggi tanaman, jumlah daun, berat basah/tanaman dan berat basah/plot. Hasil penelitian menunjukkan bahwa kecepatan angin berpengaruh terhadap bobot basah tanaman dan bobot basah/plot. Evapotranspirasi berpengaruh secara parsial terhadap tinggi tanaman, jumlah daun dan bobot basah/plot. Hasil analisa uji F simultan menunjukkan bahwa kecepatan angin dan evapotranspirasi memiliki pengaruh secara simultan terhadap tinggi tanaman. Kecepatan angin menunjukkan hubungan yang kuat terhadap tinggi tanaman, jumlah daun, dan bobot basah/plot, serta memiliki hubungan yang cukup berarti terhadap terhadap produksi bobot basah tanaman/plot.  ABSTRACT           Climate elements are closely related to weather which can reduce a cultivation business. One of the climate elements that influences plant growth and productivity is wind. Wind speed plays an important role in evapotranspiration, because it is proportional to evapotranspiration. Evapotranspiration data is used for water resources purposes and calculating water balance, especially for determining water needs for plants during the growth and production period of sorghum plants. This research aimed to determine how wind speed and evapotranspiration affect the growth and production of sorghum plants. The research was carried out at the experimental field of the BMKG Aceh Climatology Station, Aceh Besar. The research methods used include multiple linear regression analysis, T test, F test, correlation coefficient and coefficient of determination. Research parameters included plant height, number of leaves, wet weight/plant and wet weight/plot. The results showed that wind speed had an effect on plant wet weight and wet weight/plot. Evapotranspiration partially influences plant height, number of leaves and wet weight/plot. The results of the simultaneous F test analysis showed that wind speed and evapotranspiration had a simultaneous influence on plant height. Wind speed showed a strong relationship with plant height, number of leaves, and fresh weight/plot, and had a significant relationship with the production of fresh weight of plants/plot.

Abstract

ABSTRAKIndustri kertas merupakan salah satu industri penting di Indonesia yang cukup besar kontribusinya terhadap pendapatan negara. Industri kertas menghasilkan limbah yang disebut sebagai sludge. Sludge dapat dikategorikan sebagai limbah organik karena berasal dari kayu dan bubur kertas (pulp) yang diolah untuk menjadi kertas. Akan tetapi limbah tersebut terindikasi mengandung logam berat yang diperlukan sebagai bahan baku dan katalis. Pencemaran logam berat pada lahan pertanian dapat berlanjut pada tercemarnya organ tanaman seperti akar, daun, batang dan gabah yang dihasilkan. Hal ini berbahaya bagi kesehatan lingkungan dan manusia. Tujuan penelitian ini adalah untuk mengkaji unsur cuaca selama pertanaman padi dan kandungan logam berat (Hg, Cd dan Pb) pada tanaman padi (akar, batang, daun dan bulir) di kawasan industri limbah kertas di Kabupaten Malang. Penelitian dilaksanakan dengan mengkaji data cuaca dari BMKG Karangploso dan menguji organ tanaman padi di lahan pertanian di sekitar industri tersebut. Penelitian dilaksanakan Februari-Maret 2024. Hasil penelitian menunjukkan bahwa temperatur rata-rata tertinggi dan temperatur maksimum tertinggi serta lama penyinaran terpanjang dan radiasi matahari tertinggi terjadi pada Oktober 2023 berturut-turut adalah 25.6°C; 32.3°C; 92% dan 445 gr Kal/cm2, sedangkan temperatur minimum tertinggi 21.1°C pada November 2023. Curah hujan tertinggi sebesar 496 mm pada September 2022. Uji laboratorium menunjukkan bahwa logam berat Hg, Cd, dan Pb yang ditemukan pada organ tanaman padi (akar, batang, daun dan bulir) pada lahan pertanian lokasi atas, tengah dan bawah di sekitar industri kertas semuanya berada di atas ambang batas yang diijinkan.  ABSTRACTPaper industry is one of the key industries in Indonesia, significantly contributing to state income. This industry produces waste known as sludge, which can be categorized as organic waste because it comes from wood and pulp processed to make paper. However, this sludge is indicated to contain heavy metals which are needed as raw materials and catalysts. Heavy metal pollution on agricultural land can lead to contamination of plant organs such as roots, leaves, stems and grain produced. This is dangerous for the environment and human health. The aim of this research is to examine weather elements during rice planting and heavy metal content (Hg, Cd and Pb) in rice plants (roots, stems, leaves and grains) in the waste paper industrial area in Malang Regency. The research was carried out by reviewing weather data from BMKG Karangploso and testing rice plant organs on agricultural land around the industry. The research took place in February-March 2024. The results showed that the highest average temperature, highest maximum temperature, longest exposure time, and the highest solar radiation occurred in October 2023, with values of 25.6°C; 32.3°C; 92% and 445 gr Cal/cm2, respectively. Meanwhile, the highest minimum temperature was 21.1°C in November 2023. The highest rainfall was 496 mm in September 2022. Laboratory tests showed that the heavy metals Hg, Cd, and Pb were found in the rice plant organs (roots, stems, leaves and grain) on agricultural land in the upper, middle and lower locations around the paper industry, all exceeding the permitted threshold.
