Abstract

THE PROCESSING OF HOUSEHOLD WASTE INTO VARIOUS TYPES OF LOCAL MICRO ORGANISMS (LMO) LIQUID FERTILIZERS IN PUDAK VILLAGE, KUMPEH ULU DISTRICT, MUARO JAMBI REGENCY. Household waste such as leftover rice and vegetables can be used as a major component in producing Local Micro Organism (LMO). Local Micro Organism has many advantages, including being used as liquid organic fertilizer, as a decomposer in compost processing, as well as being used as bio-pesticides. The purpose of this community service project was to help the people, particularly farmers, in Pudak Village in producing LMO liquid fertilizer by providing them with relevant knowledge and technology. The technology was developed by utilizing of leftover rice and vegetables which are normally treated as unwanted household wastes. This LMO liquid fertilizer is very much needed by farmers to increase their farm output since it was proven to be able to improve plant growth and development, which in turn increase farm production eventually. In addition, this liquid fertilizer can also be sold and resulting in additional income for farmer household, and village community in general. Finally, as is stated in the objective, this community service program has produced output in the form of LMO liquid fertilizer, which then can be applied on farmers? field.

Abstract

Tolerance of Transgenic Tobacco Expressing P5CS Gene Against Drought Stress. Drought is majorosmotic stress that dramatically limit plant growth and productivity. Proline accumulation has been correlatedwith tolerance to drought stress in plants. Therefore, overproduction of proline in plants may lead to increasedtolerance against these abiotic stresses. The objectives of this experiment were to determine the effects of droughtstress at the period of 15 – 90 days after planting (DAP) on growth of T1 plants derived from transgenic GStobacco, to evaluate their tolerance against drought stress, and to determine their leaf proline content. One groupof the tobacco plants were grown in plastic pots and subjected to stress condition during the period of 15 – 90DAP. The other group was grown optimally in plastic pot up to harvest period. All tobacco plants were harvestedat 91 DAP. Leaf proline content was determined at 63 DAP (after six periods of stress). The results indicatedreduced plant height, shoot diameter, leaf number, leaf dry weight and leaf area of all tobacco plants. Stresssensitivity index calculated using leaf dry weight character grouped T1 plants derived from P5CS transgenicGS tobacco into tolerance, medium tolerance and sensitive against drought stress while that of non-transgenicGS tobacco were only medium tolerance and sensitive against drought stress. Higher leaf proline content underdrought stress was observed in all T1 plants derived from P5CS transgenic tobacco than that of non-transgenicGS tobacco. These data demonstrated that proline accumulation as an osmoprotectant and that over-expressionP5CS gene results in the increased tolerance to osmotic stress in T1 plants derived from P5CS transgenic tobacco.Key words: Proline biosynthesis, proline accumulation, sensitivity index, biomass yield Stres kekeringan merupakan masalah utama stres osmotik yang dapat menjadi faktor pembataspertumbuhan dan produktivitas tanaman. Akumulasi prolina berkorelasi dengan tingkat toleransi tanamanterhadap stres kekeringan. Oleh karena itu over-produksi prolina diduga dapat meningkatkan toleransi tanamanterhadap stres kekeringan. Tujuan penelitian ini adalah (1) untuk mengevaluasi pengaruh stres kekeringanmelalui pengurangan air terhadap pertumbuhan dan hasil tanaman TI zuriat dari tembakau GS transgenik P5CSgenerasi TO, (2) menganalisis akumulasi prolina daun tanaman TI zurlat dari tembakau GS transgenik P5CSgenerasi TO kondisi stres dan non-stres, serta (3) menganalisis hubungan antara akumulasi prolina daun padakondisi stres kekeringan dengan pertumbuhan dan hasil tanaman. Percobaan dua faktor (tembakau transgenikstres kekeringan) disusun dengan rancangan acak kelompok. Sebagian tanaman yang diuji disiram setiap hari hingga mencapai kondisi kapasitas lapang dari awal tanam sampai dengan 90 HST dan digunakan sebagaiperlakuan non-stres. Sedangkan kelompok tanaman yang lain dipelihara dalam kondisi kapasitas lapanghingga 14 HST dan diberi perlakuan stres kekeringan dari umur 15 HST hingga panen (90 HST). Kandunganprolina diukur pada umur 63 HST (setelah 6x periode stres). Hasil penelitian menunjukkan semua tanamantembakau yang diuji mempunyai tinggi tanaman, diameter batang, jumlah, berat kering dan luas daun yanglebih rendah akibat perlakuan stres kekeringan yang diberikan dibandingkan dengan kondisi non-stres.Berdasarkan hasil perhitungan indeks sensitivitas terhadap stres kekeringan menggunakan peubah bobotdaun kering per tanaman maka tanaman TI zurlat dari tembakau GS transgenik P5CS generasi TO yang diujibersegregasi untuk kategori toleran, medium toleran dan peka, sedangkan tembakau GS non-transgenikdikategorikan sebagai medium toleran dan peka terhadap stres kekeringan. Tanaman TI zurlat dari tembakau GStransgenik P5CS generasi TO menunjukkan kandungan prolina yang lebih tinggi dalam kondisi stres kekeringandibandingkan dengan tembakau GS non-transgenik. Peningkatan akumulasi prolina yang cukup tinggi akibatover-ekspresi dari gen P5CS diduga berkorelasi dengan peningkatan toleransi tanaman terhadap stres kekeringan.Kata kunci : Biosintesis prolina, akumulasi prolina, indeks sensitivitas terhadap stres, produksi biomasa

Abstract

One of the pathogen infecting peanut in Indonesia is Peanut stripe virus (PStV,), causing stripe and blotch symptoms on infected peanut leaves. The objectives of this research were to evaluate effects of PStV infection on yield of 10 introgression lines of peanut derived from crossing of Arachis cardenasii and A. hypogaea, and to determine the tolerance of these lines against PStV infection. Peanut plants were grown in polybag containing 10 kg of potting soils and were grown under glasshouse conditions. The experimental unit consisted of four plants grown separately in four containers and for each treatment was replicated four times. Peanut plants were inoculated mechanically with Bogor isolate of PStV at 15 days after planting (dap) and harvested at 95-100 dap. Results of the experiment indicated peanut cv. Gajah belonged to moderate tolerance while Kelinci was sensitive against PStV infection. Introgression line NC-CS11, CS30 and WS4 were grouped as tolerance while NC-CS51, WSl, and WS3 were moderate tolerance. The tolerance lines showed mild mosaic symptoms, did not show reduction of plant height and peanut yield upon inoculation with PStV. Introgresion line NC-CS15, CS20,CS22, and CS50 were sensitive against PStV infection, showed moderate to severe mosaic/blotch symptoms, reduction of plant height and peanut yield due to PStV infection. Among the tolerance and moderate tolerance lines, only NC-CS30 showed higher yield as compared to peanut cv. Gajah or Kelinci. Therefore, this line may be developed further as commercial peanut cultivar or be use as donor germplasm for PStV tolerance mechanisms in peanut breeding.

Abstract

Chili is a vegetable that has high economic value, but to increase production is hampered by high attacks of pests and diseases. One effort to improve it is by using mulch and selecting superior varieties of chili plants. The study aimed to examine the effect of Black Silver Plastic Mulch (MPHP) on the growth and yield of two chili varieties (Capsicum annuum L). The study used a Randomized Block Design (RBD) with one factor of combination of variety and type of mulch.. The combination of two varieties and mulching is as follows: P1 = (Mario variety + without MPHP), P2 = (Jatilaba variety + without MPHP), P3 = (Mario + MPHP variety), P4 = (Jatilaba + MPHP variety). To see the effect of treatment, the data were processed statistically by analysis of variance, and for further tests using the Smallest Significant Difference Test (LSD) at the level of ? = 5%. The combination of the use of MPHP and two chili varieties affected plant height, number of fruit crops, yield of 2X yields, and weight vanished. The use of Mario varieties given MPHP can increase yields on variable height of chili plants, number of fruit crops, yields and weight loss. Chili Mario varieties more resistant than Jatilaba using MPHP .

Abstract

Diploid species of peanut (Arachis cardenasii) showed no symptoms of PStV infection when mechanically inoculated with PStV. Some introgression lines derived from A. cardenasii and A. hypogaea hybridization have been introduced to Indonesia. Evaluation of their adaptability and yield potential were necessary before pursuing further utilization of these introgression lines. The objectives of this research were to determine yield potential of the introgression lines of peanut in green house and field conditions and to evaluate incidence of PStV infection in the field. Peanut plants were grown in the green house and in the field according to standard procedures for raising peanut. Results of the experiments showed that growth and developmental characters of the tested lines were similar between field and green house grown plants. The introgression lines generally exhibited higher secondary branches and longer to flower and harvest as compared to peanut cv. Gajah and Kelinci. The NC-CS30 line was identfied as having higher yield and bigger seed size as compared to standard peanut cultivars (Gajah and Kelinci). Therefore, NC-CS30 germplasm may be further developed as commercial peanut cultivar or be used as donor for peanut breeding in Indonesia.

Abstract

Ketidakseimbangan ekonomi sebagai salah satu dampak negatif pembangunan menyebabkan berkembangnya sejumlah sektor bisnis informal. Dan dengan pembukaan sektor pertambangan dan perkebunan di Provinsi Kalimantan Selatan secara besar-besaran selama dekade terakhir, munculnya kios-kios malam di beberapa tempat merupakan ironi pembangunan di wilayah tersebut. Penggunaan senjata tajam, obat bius, perkelahian, sampai prostitusi tersembunyi diindikasikan di sejumlah warung malam seperti di Kecamatan Kelua Kecamatan Tabalong. Oleh karena itu, melalui pendekatan kualitatif-deskriptif, keberadaan warung malam di Kelurahan Kelua dijelaskan dengan observasi, wawancara dan dokumentasi mengacu pada teknik analisis termasuk reduksi data, display data, dan penarikan kesimpulan / verifikasi. Keberadaan warung malam di sepanjang jalan Kelua telah dibina beberapa kali dalam kaitannya dengan pelaksanaan Peraturan Kabupaten Tabalong No. 08 tahun 2002 tentang Pencegahan, Pelarangan dan Penanggulangan Prostitusi, meskipun belum sepenuhnya efektif. Pertama, aspek komunikasi telah dilakukan oleh Satpol PP Kabupaten Tabalong melalui sejumlah pihak terkait di tingkat kecamatan, kecamatan, hingga desa dan bahkan dengan sejumlah pemilik warung malam dalam bentuk banding / bimbingan. Kedua, aspek sumber daya telah dipenuhi dalam hal pembinaan / tindakan teknis oleh Satpol PP. Itu hanya karena keterbatasan sumber daya aparatur di Kantor Kelurahan Kelua. Ketiga, aspek disposisi dari pelaksana umumnya seperti yang diharapkan meskipun ada beberapa aparat yang tampaknya melindungi keberadaan warung malam. Keempat, aspek struktur birokrasi dapat memainkan peran maksimum di mana sejumlah lembaga dapat berkoordinasi dengan mengacu pada Standar Operasional Prosedur (SOP) yang digariskan. Karena itu, Bupati Tabalong bersama dengan sejumlah SKPD terkait harus menyajikan pendekatan holistik. Secara teknis, Kepala Satpol PP Kabupaten Tabalong perlu mengintensifkan kegiatan pemantauan di sejumlah warung malam. Tindakan persuasif harus diambil agar warung malam diharuskan terbuka dengan penerangan yang baik, pelayan kios berpakaian sopan, dan pembatasan waktu penjualan selain penegakan hukum kegiatan pelacuran, kepemilikan senjata tajam dan obat-obatan. Selain itu, kepemilikan kartu ID untuk pelayan kios dan pengunjung juga disiplin.
