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 α = 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

The objectives of this experiments were to determine the effects of drought stress initiated at vegetative growth stage on yield of peanut, to evaluate the tolerance of six peanut cultivars against drought stress, and to determine their leaf prolin and total sugar content. One group of peanut plants were grown in plastic pots and subjected to stress condition during the period of 15-45 days (Experiment I) or 15-80 days (Experiment II) by watering them only in every 4-7 days and were harvested at days 75 (Experiment I) or at maturity (Experiment II). The other group was grown optimally in plastic pot up to harvest period. Leaf prolin content was determined at 12 (before stress), 30 (after three periods of stress), 47 (after six periods of stress), and 64 days in Experiment I and only after six periods of drought stress in Experiment II. Results indicated that drought stress that was initiated at vegetative growth stage reduced plant height, branches number, shoot and root dry weight, and peanut yield. Sensitivity index calculated based on peanut yield showed that peanut cv. Jerapah and Singa were a medium tolerance while Gajah, Kelinci, Macan, and Simpai were sensitive against drought stress. Higher increased in leaf proline content after drought stress was observed in peanut cv. Jerapah and Singa, while less increased was observed in peanut cv. Gajah, Kelinci, Macan and Simpai. Total leaf sugar content of peanut cv. Jerapah, Gajah, Macan and Simpai decreased under drought stress while that of Singa and Kelinci were the same as that under optimal condition. The ability to increase leaf proline content and maintain total leaf sugar content under drought stress could be used as indicators of drought tolerance in peanut cultivars.

Abstract

The government of the South Kalimantan Province moved the provincial capital from Banjarmasin to Banjarbaru at the end of 2011. However, there has not been a clear decision as to what the government’s old building will be used for. One thing is clear, the utilization has to be optimized by considering the local government regulations. The aim of the research is to examine the highest and the best alternatives of utilization that can be adopted for such an asset. Non-probability sampling method was used in the research to find the alternatives. The alternatives were analyzed by using the highest and the best use analysis as the relevance test instrument for each of them. After analyzing the alternatives, the benefit-cost ratio (BCR) analysis was conducted to analyze the alternatives prior to determining their feasibility. Legal analysis, physical analysis, financial analysis, and the maximum productivity analysis were the stages conducted on the research based on highest and best use analysis. Based on the result of the research, the alternative which is feasible to do is that the building is used for other governmental or public purposes. Through the analysis, the alternative meets the criteria of the analysis as mentioned before with NPV Rp. 747,439,143 and BCR 1.024. Furthermore, according to 42.5 percent of the respondents, the building is best used for UPT offices and other institutions.

Abstract

Referring to the Preamble of Constitution of the Republic of Indonesia, every citizen entitled to a proper education is no exception to children with physical, mental-intellectual, social, and emotional disabilities commonly called Special Children (ALB) or Children with Special Needs (ABK). For them, special schools (SLB) from primary to intermediate level are the main hope for fulfillment of non-conventional education desires not obtained from other educational institutions. In SDLB Negeri Sungai Malang, the quality of basic education provided in general is sufficient enough to meet the thirst of education for students in terms of teachers, curriculum, academic atmosphere, and scientific resources. Behind that, there is a lack of discipline in the teacher's aspect, the lack of technology in the learning process in the curriculum aspect, the expansion of school land in the academic atmosphere aspect, and the lack of visual aids on the scientific aspect. In the future, it is necessary to improve the quality of education service in SDLB Negeri Sungai Malang by the Head of Education Office in Hulu Sungai Utara Regency through the expansion of school land of SDLB Negeri Sungai Malang for the fulfillment of academic atmosphere besides the provision of digital technology facilities and a number of props to support the learning process for ABK with the efforts of the Headmaster of SDLB Negeri Sungai Malang to improve teacher discipline through continuous direct/indirect supervision techniques and the use of electronic attendance (finger print) in addition to the exemplary performance of the Headmaster to the teachers.

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.
