Abstract

Abstract Fulfilment of nutrients in the land must be cultivated by increasing the physical and biological properties of the soil so that the presence of nutrients in the ground will be more maintained. The application of technology often used in land use efforts is mostly only focused on chemical fertilization activities. One alternative to reduce the use of chemical fertilizers is to use liquid organic fertilizer (POC) in thitonia and calotropis plant extracts and cow urine. This study aims to obtain a combination of plant extracts that can increase the growth and yield of maize plants and the best blend of biourin and plant extracts in suppressing pests and diseases in maize. The research was carried out on the land of the Faculty of Agriculture, Hasanuddin University (Eksfarm), Makassar City, South Sulawesi, from September to December 2019. The research was arranged using a split-plot design with the first factor as the main plot. The application consisted of 4 levels namely without spraying (K), a combination of bio urine, tithonia extract, calotropis extract, pineapple MOL (B1), bio urine, tithonia extract, calotropis extract (B2) and bio urine (B3) with each application dose of 40 ml/1 liter of water. The second factor as a sub-plot was the spraying interval at the age of 14 DAS which consisted of 3 levels, namely without application, once a week, once in two weeks. The results showed that the application of biourin could increase the growth rate and yield of corn plants. The combination of biourin with plant extracts had a significant effect on the level of pest attack that attacked the leaves and cobs of corn plants and the best interaction between the intervals of application of biourin in increasing the productivity of spraying plants per two weeks.     Keywords: Biourine, Spodoptera litura, Tithonia, Calotropis, Pest attack rate

Abstract

Araecerus fasciculatus (Coleoptera: Anthribidae) is a primary pest mostly found in cocoa bean storage. Controlling A. fascuculatus is highly necessary, as this action would also reduce infestation of secondary pests. Utilization of natural materials as bait or trap is one applicable method to lessen damage and loss during storage. Vitex trifolia L., Acorus colomus L., and Andropogon nardus L are plant species that posess insecticidal properties that can be used to control post harvest pests. Materials used in this experiment are leaves of V. trifolia, rhizome of A. colomus and leaves of A. nardus. The three types of materials are blended and sieved with 300 mesh until finely broken up for make powder formulation. As much as 1 g of powder extract was taken then mixed with additional substract (water + CMC + saw dusts). The mixtures were then shaped in the form of ellipse resembling cocoa beans with approximately similar weight of 0.6 g (± 20 beans). Results show that V. trifolia and A. nardus are highly repellent (90.5 % and 94.5%) to A. fasciculatus, and crhizome of A. colomus is attractant to A. fasciculatus.

Abstract

Spodoptera frugiperda is a novel invasive pest of maize crops. Therefore, studies on this pest are limited. Research on the use of artificial diets in S. frugiperda larvae rearing is essential to facilitate the provision of test larva stocks for lab-scale study purposes. The aim of this research was to figure out the effect of an artificial diet from soybeans as a protein source on S. frugiperda rearing. The parameters observed in this research were larval-stage longevity, larval survival rate, pupa size, sex ratio, pupal-stage longevity, pupal survival rate, fecundity, and nutritional index. The results showed that an artificial diet with soybeans had a significant effect on sex ratio, pupal survival rate, relative consumption rate (RCR) 4.89 g/g/day (4th instar); 1.99 g/g/day (5th instar), approximate digestibility (AD) 98.39% (4th instar); 95.45% (5th instar), and fecundity, but it did not have any significant effect on larval-stage longevity, larval survival rate, pupa size, pupal-stage longevity, the efficiency of conversion of ingested food (ECI) 3.68% (4th instar); 7.84% (5th instar), and efficiency of conversion of digested food (ECD) 3.76% (4th instar); 8.27% (5th instar). Artificial diet-based soybean was highly potential to be used in S. frugiperda rearing.

Abstract

Excessive use of pesticides confers several ecological and environmental consequences. In this research, we evaluated arthropod occurrence on shallot crops in Palu Valley, Central Sulawesi as an impact of pesticide application in different frequencies. Almost all farmers used synthetic pesticides for controlling pests and diseases where 46.7%, 43.3%, 10.0% of them applied in high, moderate, and low frequency, respectively. By comparing to the last application, the first reduced arthropod diversity index, evenness index, and abundance by 13.8%, 6.7%, and 70.6%, while the second by 7.3%, 2.3%, and 33.5%, respectively. Analysis of the dynamic abundance of pests and natural enemies in seven weeks observation indicated that the pests abundance at low and moderate levels was no different. Whereas predator abundance at low frequency was significantly different with moderate and high rate and between the last two not distinct and the presence of parasitoids was not observed at all, it means the natural enemies were susceptible to pesticides. These data showed the negative impact of pesticides application to arthropods including pests resistance and natural enemies lost; therefore it is necessary to minimize the use of pesticides and integrated pests.

Abstract

Kabupaten Gowa merupakan salah satu daerah sentra tanaman sayuran yang terletak di sebelah selatan Provinsi Sulawesi Selatan. Sayuran merupakan salah satu tanaman hortikultura yang banyak dibudidayakan  tetapi  pengelolaan tanaman sayuran bersifat konvensional dengan asupan senyawa kimia sintetik yang tinggi terrmasuk pupuk dan pestisida sintetik. Pengunaan bahan kimia sintetik yang tinggi dalam pengelolaan tanaman sayuran akan membahayakan kesehatan konsumen dan tidak ramah lingkungan. Keprihatinan terhadap isu lingkungan dan  preferensi  konsumen yang tinggi terhadap produk sayur organik maka Fresko Organik yang berlokasi di Desa Pacellekang Kecamatan Pattalassang Kabupaten Gowa telah melakukan budidaya sayuran secara organik tetapi masih banyak kendala yang dihadapi sedangkan pada kelompok masyarakat (KWT ASYTA) adalah yang ada di lokasi tersebut juga tidak berkembang/produktif karena tidak mendapat pendampingan/bimbingan terutama bagaimana sistem budidaya sayuran yang ramah lingkungan semuanya masih mengandalkan penggunaan senyawa kimia sintetik. Dari hasil pengamatan dilapang dan  wawancara/diskusi, maka permasalahan yang ditemukan adalah kurangnya pemahaman dan teknologi bagaimana memanfaatkan potensi sumber daya lokal yang ada misalnya pemanfaatan teknologi BABT terutama untuk pembuatan pupuk organik  dan untuk pengendalian/pengelolaan hama dan penyakit tanaman. Solusi yang ditawarkan adalah dengan melakukan pelatihan pembuatan pestisida dan pupuk organik yang berasal dari bahan alami bioaktif tanaman dan implementasi penggunaan BABT pada lahan Fresko organik sebagai tempat pembelajaran terhadap dampak penggunaan BABT dalam upaya mengurangi serangan hama. Pemanfaatan BABT mulai dari pengenalan jenis jenis BABT yang bisa dimanfaatkan sebagai pengendali hama dan pupuk organik kompos. Metode yang diterapkan adalah: penyuluhan, pelatihan, demonstrasi teknologi, aplikasi teknologi serta pendampingan yang dilakukan secara partisipatif. Kata kunci: Pestisida nabati, BABT, sayur organik. ABSTRACT Gowa Regency is one of the vegetable growing centers among the 23 regencies and municipalities in South Sulawesi Province and is located in the south of the province. Vegetables are one of the most widely cultivated horticultural crops, but the management of vegetable crops is conventional, with a high intake of synthetic chemical compounds, including synthetic fertilizers and pesticides. The high use of synthetic chemicals in the management of vegetable crops will endanger the health of consumers and is not environmentally friendly. Concerned about environmental issues and high consumer preferences for organic vegetable products, the organic frescoes are located in Pattalassang sub-district, Pacellekang village, and Pacellekang district. Gowa has been cultivating vegetables organically, but there are still many obstacles to face. The community group (KWT ASYTA) says that those in that location are also not developing or productive because they don't get assistance or guidance, especially since an environmentally friendly vegetable cultivation system still relies on the use of synthetic chemical compounds. From the results of field observations and interviews and discussions, the problems found are lack of understanding and technology on how to take advantage of the potential of existing local resources, for example, the use of BABT technology, especially for the manufacture of organic fertilizers and for the control and management of pests and plant diseases. The solutions offered are conducting training on making organic pesticides and fertilizers derived from natural bioactive plant ingredients and Implementation of the use of BABT on organic Fersko land as a place to learn about the impact of using BABT in an effort to reduce pest attacks. The utilization of BABT, starting with the introduction of the types of BABT that can be used as pest control and organic compost fertilizer. The methods applied are counseling, training, technology demonstration, technology application, and mentoring, which is carried out in a participatory manner. Keywords: Botanical pesticides, BABT, organic vegetables.

Abstract

Spodoptera frugiperda J.E. Smith, or fall armyworm (FAW), is a significant pest in maize plants and can reduce crop yields. Synthetic insecticides are still used to control S. frugiperda, but their use harms the environment and non-target organisms and can cause pests to become resistant. For this reason, alternative environmentally friendly technologies are needed, such as habitat management by planting insectary plants. This research aims to evaluate the potential of insectary plants to attract beneficial arthropods to suppress the S. frugiperda population and minimize the damage caused. This research activity was carried out using field research. The treatment in this research was the type of insectary plant used, and as a comparison, observations were made on land managed by farmers. The research results show that habitat management by planting insectary plants can increase the population of beneficial arthropods such as Coccinellidae, Formicidae, Miridae, Staphylinidae, and Araneidae. Increasing the population of beneficial arthropods can suppress the population of S. frugiperda so that its damage decreases and yields increase. These results show that planting insectary plants has the potential to prevent outbreaks of S. frugiperda, which can be combined with the application of other environmentally friendly technologies.

Abstract

Bawang merah salah satu komoditas sayuran penting yang banyak dibutuhkan masyarakat sebagai bumbu penyedap masakan. Kebutuhan dari tahun ke tahun mengalami peningkatan seiring dengan bertambahnya jumlah penduduk dan beragamnya produk olahan. Ketersediaannya yang langka menimbulkan keresahan di tengah masyarakat dan mempengaruhi inflasi secara nasional. Sebagai komoditas penting maka pemerintah mencanangkan produksi nasional bawang merah sebesar 1.410.847 ton. Untuk mencapai produksi tersebut dibutuhkan benih sebanyak 155.556 ton umbi bibit dan biji bibit (True shallot seed) sebanyak 28.590. Selama ini, biaya usahatani bawang merah khususnya dari bibit dapat mencapai 60% dari total biaya produksi dengan mutu bibit yang kurang memenuhi syarat agronomi. Karena bibit diperoleh dari umbi yang diseleksi dari hasil panen umbi untuk konsumsi. Semestinya produksi untuk bibit berbeda cara pe-nanganannya dengan produksi untuk konsumsi. Perbanyakan tanaman bawang merah dengan umbi memiliki kekurangan di antraanya biayanya mahal karena dibutuhkan bibit dalam jumlah besar (1,0-1,5 ton/ha), mudah rusak dan umur simpannya singkat (kurang 3 bulan) serta mengalami masa dormansi. Sedangkan keuntungan menggunakan biji adalah biaya produksinya rendah karena dibutuhkan 5-6 kg/ha, hemat biaya transportasi bibit,  umur simpan lebih lama (2 tahun), ukuran umbi  lebih besar, dan produksinya lebih tinggi. Penggunaan biji untuk bibit bawang merah merupakan alternatif dalam membudidayakan bawang merah lebih murah dengan produktivitas yang tinggi.   Kata Kunci, Bawang merah, biji untuk bibit, dan umbi untuk bibit.

Abstract

Sayuran merupakan tanaman yang mempunyai peranan yang sangat penting dalam pemenuhan gizi masyarakat dan mempunyai nilai ekonomis.  Desa Benteng Alla adalah salah satu desa yang berada di Kecamatan Baroko Kabupaten Enrekang yang merupakan salah satu penghasil sayuran terbesar di Sulawesi Selatan dan membudidayakan sayuran dengan teknologi konvensional dengan dengan penggunaan pestisida sintetik yang tinggi antara 1 sampai 2 kali per minggu. Dari hasil wawancara sebelumnya diketahui petani belum memahami dan mengetahui alternatif pengganti pestisida sintetik padahal di desa tersebut terdapat beberapa sumber biopestisida nabati. Masalahnya petani tidak mengenal tanaman sebagai sumber biopestisida nabati dan tidak mengetahui bagaimana cara membuat dan mengaplikasikannya. Berdasarkan hal tersebut diperlukan pengenalan bahan alami tanaman lokal disekitar pertanaman petani sebagai sumber biopestisida untuk dapat dimanfaatkan dalam upaya pengendalian hama dan penyakit pada tanaman sayuran. Tujuan pelatihan ini adalah untuk meningkatkan pengenalan, pemahaman, dan pengetahuan tentang tanaman lokal sebagai biopestisida yang dapat dimanfaatkan dalam budidaya sayuran petani untuk mengurangi penggunaan pestisida sintetik. Ada lima jenis tanaman lokal yang didapatkan antara lain: Toona sureni, Ageratum conyzoides, Chromalaena odorata, Tithonia diversifolia, dan Tagetes erecta.Kata kunci: Tanaman lokal, biopestisida nabati, sayuran organik.
