Abstract

ABSTRACT This study aims to determine the effect of the combination of liquid and solid organic fertilizer on the growth and production of peanuts (Arachis hypogaea L.). This research was carried out for four months, from January to June 2021, at the screen house of Musamus University, Merauke. The method used in this study was a Factorial Randomized Block Design (RBD) with two treatment factors, the first factor being liquid organic fertilizer and the second factor being solid organic fertilizer. The results showed that applying liquid organic fertilizer and solid organic fertilizer had no significant effect on all experimental parameters. However, using solid organic fertilizer with a dose of 200 g gave an average yield that tended to be better for the plant height parameter, which was 24,64 cm, and the number of branches reached 5,33 branches. The application of 300 ml of liquid organic fertilizer gave an average yield that tends to be better on the parameters of the number of pods, namely 24,33 pods dry pod weight 25,00 g, the number of pods contained 23,33 pods. In contrast, the two factors gave an average value in the combination treatment. The average tended to be suitable for the parameters of wet pod weight 34,67 g, and the number of empty pods 4,33 pods. In the highest treatment, the importance of dry pods when converted to hectares resulted in 6,25 tons/ha production.

Abstract

This study aims to determine the distribution pattern and intensity of the attack of the corn cob and stem borer in Merauke Regency, Papua Province. This study uses purposive sampling method to determine the sampling by determining the specific characteristics that are in accordance with the research objectives, so that it is expected to determine the spread of insect pests. This research was conducted in 4 (four) villages in Semangga District and Tanah Miring District which have a lot of corn plants. One village was taken from each sub-district as the sampling location. Then each village is determined one location with an area of ± 0.5 ha. Sampling at each location used the diagonal slice method, so that in each location there were five sub-locations. Each sub-location 20 clumps were taken, and observations were made every 10 days on 42-day-old plants until harvest. Based on the results of the study, the highest percentage of attacks by Ostrinia furnacalis was in Semangga District in Semangga Village (6.71%), and the lowest was in Waninggap Say Village (3.13%). Meanwhile, the highest percentage of Helicoperva armigera attacks was in Isanombias Village (7.12%), and the lowest was in Muram Sari Village (3.12%). The low pest population is caused by farmers already using insecticides in pest control. The distribution pattern of Ostrinia furnacalis and Helicoperva armigera in Merauke Regency was random, where individuals spread out in several places and grouped together in other places, this was due to the homogenous environment of maize cultivation.

Abstract

Mengembangkan pertanian organik perlu memperhatikan beberapa aspek antara lain kesehatan dan kesuburan tanah, keseimbangan organisme di alam serta dapat memperbaiki kualitas tanaman namun tetap mempertahankan nilai produksi suatu komoditi tanpa menggunakan bahan kimia sintetis. Tujuan dari kegiatan pengabdian ini yaitu meningkatkan pengetahuan, sikap dan tindakan kelompok tani di Kampung Yasa Mulya, Distrik Tanah Miring, Merauke tentang pentingnya mengenal hama, musuh alami tanaman padi serta dapat menggunakan bahan tanaman sebagai bahan insektisida nabati. Metode observasi dilakukan untuk mengumpulkan informasi tentang teknik budidaya padi yang diterapkan dan masalah yang dihadapi petani. Selanjutnya dilakukan sosialisasi kepada kelompok tani tentang hama, penyakit, musuh alami serta pelatihan pembuatan insektisida nabati. Tahap evalusi dilakukan melalui hasil uji coba yang telah dilakukan oleh petani. Berdasarkan hasil observasi dan sosialisasi diketahui bahwa perilaku petani dalam mengaplikasikan pestisida didasarkan pada pemahaman sendiri, pengalaman teman atau saudara serta kekhawatiran akan gagal panen. Persentase biaya yang dikeluarkan petani untuk membeli pestisida sampai dengan 80%. Selain itu, belum pernah dilakukan tindakan pengendalian lain seperti memanfaatkan bahan-bahan alami atau menggunakan entomopatogen.selain menggunakan pestisida sintetik.

Abstract

Kampung Wasur terletak di dalam wilayah Taman Nasional Wasur yang merupakan salah satu dari 50 taman nasional di Indonesia. Penduduk asli di wilayah Kampung Wasur merupakan komponen penting dalam upaya pelestarian taman nasional tersebut karena merekalah yang sehari-hari hidup dan memanfaatkan sumber daya di dalam kawasan tersebut. Ironinya, sebagian besar masyarakat asli di Kampung Wasur masih memiliki tingkat kesejahteraan yang rendah. Rendahnya tingkat kesejahteraan mereka, merupakan dampak dari mata pencaharian penduduk asli yang masih berkutat pada upaya berburu dan meramu. Rendahnya tingkat pendidikan dan keterampilan masyarakat asli Papua membuat mereka kesulitan untuk mencari pekerjaan lain dengan upah yang layak Masyarakat ini adalah bagaimana meningkatkan keterampilan masyarakat asli Papua di Kampung Wasur untuk melakukan pertanian organik dan bagaimana mengoptimalkan sumber daya alam di Kampung Wasur yang sangat terbatas tanpa menggangu keseimbangan ekosistem di wilayah tersebut. Untuk mengatasi kedua masalah tersebut, solusi yang kami tawarkan adalah dengan melakukan pelatihan budidaya tanaman organik dengan sistem irigasi tetes untuk meningkatkan pendapatan dan ketahanan pangan masyarakat di Kampung Wasur. Luaran yang telah dihasilkan adalah tersedianya demplot mini pertanian organik di Kampung Wasur, meningkatnya pengetahuan masyarakat mengenai budidaya tanaman secara organik, publikasi pada media massa Kompas TV Merauke (https://www.youtube.com/watch?v=_HjMUijmSxg), serta Lensa Merauke. com (https://lensamerauke.com/2022/11/12/tim-dosen-unmus-latih-warga-kampung-wasur-kembangkan-pertanian-organik/), sementara draft artikel pengabdian akan disubmit pada akhir Desember 2022.

Abstract

This study aims to determine the relationship of metabolite compounds in meliaceae plants to the preference of Hypsipyla sp. This research was conducted at the Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Sam Ratulangi State University, Manado BALITKA Laboratory, Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, State University of Gorontalo and sending samples to the Pharmacy Laboratory of Sendai Japan to see the NMR structure. This study was designed in a Latin square design with 5 treatments and 5 replications. The total number of plants in all treatments was 250 plants. The determination of secondary metabolites was carried out in five stages, namely: 1) sample collection and processing, 2) extraction, 3) purification, 4) phytochemical test, 5) identification of compounds using UV-Vis and IR spectrophotometers. The sample materials used were dry samples of langsat, duku, mindi, and mahogany leaves consisting of large mahogany and small mahogany. The results of phytochemical screening on samples of lansium, duku, chinaberry, large mahogany and small mahogany in the n-hexane, ethyl acetate and water fractions showed positive results for flavonoids and steroids, while for alkaloids, terpenoids and saponins showed negative results. The results of the analysis showed that small mahogany plants contained high starch content of 43.72 g/mL, high fat content of small mahogany plants of 24.15% and high protein content of Langsat plants of 9.01 g/mL. The level of preference Hypsipyla sp prefers small mahogany plants compared to other plants. The number of mahogany stomata compared to other plants regulates the rate of evaporation in which will also release secondary metabolic compounds as attractants to attract insects to plants. The main flavonoid groups in mahogany are Quercetin 3-O-β-D-galactopyranoside, Quercetin 3-O-β-D-glucopyranoside, and quercetin 3-O-α-L-rhamnopyranoside.  Key words: phytochemicals; plant metabolites; quercetin; mahogany; Hypsipyla sp.

Abstract

Perkembangan dan penerapan pendekatan pertanian organik terus meningkat seiring dengan semakin jelasnya dampak negatif dan bertambahnya kesadaran penduduk tentang bahaya penggunaan bahan-bahan kimia. Sistem pertanian organik yang bertujuan untuk tetap menjaga keselarasan  dengan sistem alami, dengan memanfaatkan dan mengembangkan semaksimal mungkin proses-proses alami dalam pengelolaan usaha tani. Secara umum para petani kampung Bokem belum memiliki pengetahuan dan keterampilan untuk bercocok tanam organik. Untuk itu sangat perlu dilakukan pelatihan keterampilan bercocok tanam organik sehingga dari awal konsep ini sudah diterapkan oleh masyarakat Bokem. Hal ini diharapkan kedepan bahwa petani Kampung Bokem dapat menghasilkan produk sayuran yang bebas pestisida dan pupuk kimia. Selain itu dengan adanya pelatihan bercocok tanam sayur-sayuran secara organik akan meningkatkan perekonomian masyarakat dan membuat masyarakat mengkonsumsi sayuran sehat. Jenis luaran yang akan dihasilkan dari kegiatan ini adalah petani kampung Bokem dapat membuat Pupuk Organik Cair sehingga tidak bergantung pada pupuk kimia atau bahkan bebas pupuk kimia. Selain itu penggunaan bahan alam disekitar kampung dapat digunakan sebagai pestisida nabati. Lebih lanjut hasil yang diharapkan dari pengabdian ini adalah agar petani kampung Bokem menghasilkan sayuran organik dan kedepannya menjadi sentra produksi pertanian organik. Kata kunci: Usaha tani, Organik, Kampung Bokem. ABSTRACT The development and application of organic farming approaches continue to increase along with the clearer negative impact and increasing awareness of the population about the dangers of using chemicals. An organic farming system that aims to maintain harmony with natural systems, by utilizing and developing as many as possible natural processes in farming management. In general, Bokem village farmers do not have the knowledge and skills to grow organic crops. For this reason, it is very necessary to conduct training in organic farming skills so that from the beginning this concept has been applied by the Bokem community. It is hoped that in the future the farmers of Kampung Bokem can produce vegetable products that are free of pesticides and chemical fertilizers. In addition, training in organically grown vegetables, will improve the community's economy and make people consume healthy vegetables. The type of output that will be produced from this activity is that Bokem village farmers can make liquid organic fertilizer so they don't depend on chemical fertilizers or are even free of chemical fertilizers. In addition, the use of natural materials around the village can be used as vegetable pesticides. Furthermore, the expected result of this service is that Bokem village farmers produce organic vegetables and in the future become centers of organic agricultural production. Keywords: Farming, Organic, Bokem Village.
