Abstract. Saidah, Wahyuni AN, Muchtar, Padang IS, Sutardi. 2020. The growth and yield performance of true shallot seed production in Central Sulawesi, Indonesia. Asian J Agric 4:  18-22. Shallot  (Allium ascalonicum L.) is a vegetable commodity that has high economic value and market prospects. So far, planting shallots using seeds from tubers, but planting onions with seeds is better and cost efficiency and seeds are healthier. The aim of this study was to determine the growth and yield performance of true shallot seed production in Central Sulawesi, Indonesia. The study was conducted from May to September 2018 in Wuasa Village, North Lore Sub-district, Poso District at an altitude of 1083.7 meters above sea level. Research with an on farm research approach on farmer's land as a cooperator covering an area of ??3000 m2. The study used the Probability Sampling Method with 10 replications. The results showed that the growth and yield performance of true shallot seed in Central Sulawesi was quite high. This is due to the suitability of the climatic conditions and cultivation technology that has been applied. In the yield component, the percentage of flowering plants was quite high at 78% with a number of capsules/flowers at 80.67. The success of true shallot seed production is expected to be able to replace the source of seed from the tuber which has been containing viruses and diseases carried by the tuber seeds.

Abstract:This study aims to examine the effect of Net Profit Margin, Earning per Share, Return onEquity, and Price to Book Value on stock prices in LQ-45 companies in 2016-2018. The method usedis quantitative methods. This study used SPSS version 25. The results partially explain that NetProfit Margin and Return on Equityhave a significant negative effect on stock prices, Earning perShare and Price to Book Value have a significant positive effect on stock prices. Meanwhile,simultaneously Net Profit Margin, Earning per Share, Return on Equity, and Price to Book Valuehave a significant effect on stock prices. Based on the calculation of the coefficient of determination,it shows that the stock price is influenced by the independent variables in this study of 81.5% and theremaining 18.5% is influenced by other variables outside of this study.Keywords: Stock Price, Net Profit Margin, Earning per Share, Return on Equity, and Price toBookValue

Abstract

The installation of elbow ducting in closed-loop wind tunnel installation will cause a pressure drop. Pressure drop was caused by flow separation and secondary flow phenomenon in the elbow ducting. The test section used in this experimental study was an octagonal elbow 90º with radius ratio (rm/Dh) = 0.6. Diameter hydraulic (Dh) elbow of 806 mm. In this study, the Reynolds number is measured based on the free flow velocity (U∞) inlet section, that is ReDh = 4.63x105. The experimental results showed the pressure drop is ΔCp = 1.46 for Re = 4.63x105. This difference in pressure value between the outer and inner (ΔCp) of the elbow ducting was caused by secondary flow. The secondary flow was observed through a horizontal velocity profile where at xi/Dh = 1.35, fluid flow was accelerated on the inner wall and decelerated on the outer wall of the ducting elbow. Then, at xi/Dh = 1.63 to xi/Dh = 2.01, there are gradual shifts of the velocity profile where the fluid flow is accelerated toward the outer wall.

Abstract

Terbatasnya transportasi publik yang nyaman serta juga kecenderungan masyarakat menggunakan kendaraan secara individu telah menciptakan peluang pekerjaan baru, yakni ojek. Bagi pengemudi ojek, sepeda motor untuk melayani pelanggan merupakan tulang punggung kehidupan ekonomi mereka. Sehingga perawatan sepeda motor menjadi kebutuhan utama. Namun dengan penghasilan yang hanya 100 ribu rupiah per hari, maka biaya perawatan menjadi persoalan tersendiri. Oleh karena itu, pengabdian masyarakat ini dilakukan dalam rangka membantu para pengemudi ojek dalam merawat sepeda motornya secara gratis. Bekerja sama dengan mahasiswa yang tergabung dalam Lembaga Bengkel Mahasiswa Mesin (LBMM), para dosen pengabdi dari Departemen Teknik Mesin, Fakultas Teknologi Industri dan Rekayasa Sistem, Institut Teknologi Sepuluh Nopember, telah berhasil melakukan servis gratis untuk 75 sepeda motor pengemudi ojek di sekitar kampus. Seluruh pengemudi ojek peserta kegiatan ini menyatakan sangat puas dan berharap kegiatan servis gratis ini dapat dilakukan secara rutin, karena sangat membantu mereka dalam melakukan pekerjaannya sehari-hari.

Abstract

The purpose of the study was to determine the effect of pruning and land use under shelter using a planting system on the response of cocoa yields (Theobroma cacao L.) and the vegetative growth component of jack bean (Canavalia ensiformis L.) carried out from Juny 1 to August 31, 2021 in Plosokerep, Patuk, Gunung Kidul, Yogyakarta Special Region. The study experiment arranged a Split Plot Design, the main plot of the planting system (monoculture and intercropping) and the pruning plot children, namely without pruning, 30% pruning, and 60% pruning. The results showed that there was no interaction between the planting system and pruning the vegetative growth variables of cocoa plants, but the treatment of the planting system, namely, monocultures produced a lower dry seed weight than intercropping on the cocoa yield variable and pruning had no effect on the variable components of jack bean growth.

Abstract

Sorghum is a drought-tolerant crop that can contribute to Indonesia’s food security and income generation. However, this potential often fails to improve farmers’ income and welfare unless accompanied by economic feasibility, particularly in marketing practices. This study examined market efficiency and partnership models in sorghum development in Daerah Istimewa Yogyakarta and Central Java Provinces. The research analyzed the marketing cost, marketing margin, farmers’ share, and partnership cultivation models of the sorghum. The data were collected through surveys, interviews, and observations to 120 sorghum farmers and 60 traders. The study utilized descriptive statistics, ANOVA to compare farmers’ share in the different marketing channels, and the Analytic Hierarchy Process (AHP) to select the partnership models. The results unveiled Channel II which consisting of farmers, village collector traders, traders outside the city or regency, and national companies, produced the highest marketing margin. Meanwhile, Channel III, comprising farmers, village collector traders, and the local feed industry, generated the highest farmers’ share. The study revealed that sole proprietorship partnerships were the farmers' dominant choice in the sorghum business. Nevertheless, the partnership model with feed industry had also formed in the research area.

Abstract

Sleman Regency is one of the regions with extensive agricultural land and the largest rice producer in the Special Region of Yogyakarta Province. To increase rice production in East Sleman, water services are prioritized. This is achieved through the construction of irrigation networks, including dams, canals, culverts, gutters, and sluice gates. This ensures that the operation and maintenance of existing irrigation channels are prioritized. Operations and Maintenance (O&M) are conducted to monitor the condition of irrigation structures in each irrigation area by calculating the extent of physical damage and maintenance costs. To support smooth operation and maintenance activities, a method is needed that can quickly access information on the condition of irrigation structures in each irrigation area using a Spatial Data System, which provides links via HTML Popup, containing information on the condition of the irrigation structures. Through monitoring, damage and maintenance costs are calculated, including damage to the physical structures, such as river stone masonry and plaster. The total volume of river stone masonry in the East Sleman Irrigation Area is 1,188.20 m3 and plastering 3,599.46 m2, while the costs required for the Operation and Maintenance of River Stone Masonry are @ Rp. 929,298.70/m3 so that it requires a cost of Rp. 1,104,201,265.00 and for plastering @ Rp. 52,116.69/m2 so that it requires a cost of Rp. 187,591,905.00. For data on the operation and maintenance needs of each irrigation area, it is easier to store, manage, and display using spatial data from GIS (Geographic Information System) applications.
