Abstract

ABSTRACTThis study aims to determine To analyze the effect and efficiency of the use of factors of production such as land, labor, seed, fertilizer Urea, SP36, KCl fertilizers and herbicides Gramaxone on hybrid corn production. in the Sugih Waras village Muara Sugihan District Banyuasin Regency. The method used is the method of a survey of corn growers in the Sugih Waras village Muara Sugihan District Banyuasin Regency. Sampling method is done using a random method (simple random sampling) using the formula Slovin. The number of members of the population of hybrid corn farmer in the village of 168 on the Sugih Waras then the amount calculated into the formula Slovin with a confidence level of 85%, 85% confident that the true and the research results with significance level of 0.15, then a sample of the entire population of hybrid maize farmers which can be taken are 35 farmers. Data processing method is the method of interview data collected in this study included primary data and secondary data. Primary data obtained from respondents through direct interviews and field observations accompanied by a list of questions has been provided while secondary data obtained from the competent institutions or agencies associated with this research. Data were processed using mathematical models and presented in tabular form. The results showed that the factors of production labor, urea, fertilizers and herbicides Gramaxone SP36 no significant effect on the production of hybrid corn. While the seeds, area of land and fertilizer KCl significant effect on the production of hybrid corn. Based on the level of inefficiency of production factors such as labor, land, urea and herbicides Gramaxone inefficient that need to be reduced in order to achieve an efficient level. While the factors of production seed, fertilizer KCl, and SP36 has not been so efficient that need to be added to reach the level of inefficiency.

Abstract

Studi ini bertujuan untuk memberikan arahan pengembangan terhadap kawasan Talise  (sepanjang koridor Jl. Yos Sudarso) sebagai salah satu kawasan yang berada di Pusat Kota Palu dan terletak di pinggiran pantai Teluk Palu. Metode yang digunakan adalah metode survei dengan pendekatan analisis kualitatif terhadap aspek-aspek penataan lingkungan dan bangunan. Hasil studi menunjukkan bahwa di kawasan Talise telah terjadi pergeseran penggunaan lahan tambak penggaraman tradisional dan pemberian izin pembangunan dari pergeseran lahan tersebut ke penggunaan lahan sebagai lokasi perdagangan dan jasa. Untuk mengantisipasi hal tersebut maka pengembangannya kedepan hanya diarahkan untuk aktivitas “wisata” berupa pembangunan prasarana seperti : hotel, restauran, dan toko-toko cenderamata (gift stores) dengan orientasi bangunan menghadap ke arah pantai Teluk Palu, sementara batasan lahan konservasinya dapat dimanfaatkan sebagai ruang terbuka hijau ataupun kegiatan rekreasi wisata pantai dan olah raga. Selain itu, kawasan ini juga diarahkan sebagai  pintu gerbang penerima (welcome street), dan kawasan yang mengandalkan rekreasi pemandangan (view recreation) ke arah pantai Teluk Palu

Abstract

Research aim to monitoring and evaluating differences in spatial planning product that it arranged with existing conditions in Kabupaten Poso. The method was survey method with quantify analysis approach to different counts in spatial planning monitoring aspects in to three groups populations, land use, and space structures. Analysis result showed for all spatial planning monitoring aspects have very significant differences and have not relevant with spatial planning product in Kabupaten Poso condition, it also influenced by regional wide become two regions as Kabupaten Poso and Kabupaten Tojo Unauna, so spatial planning product must be totally revised.

Abstract

This study aims to model the growth trend of the extent of land use for building based on thecarrying capacity of land in Palu city which is known as Bay City in accordance with theprediction of time. Methods of research were carried out with the approach of spatial andquantitative methods. The results show that Palu city as Bay City has the characteristics ofurban land that is quite specific to the protected area. There is still available land forbuilding i.e.: ± 13.151,13 ha (34.74%) with a growth rate of land use for building in thefuture 2.72% per year, area of cultivation will be fully filled in the year 2056 with thecapacity of 1.052.730 people. Carrying capacity of land in Palu city until the year 2056 hasnot exceeded the threshold, either by the land consumption per capita or by the level density.

Abstract

This article presents a study on optimizing Tungsten Inert Gas (TIG) welding on mild steel (SPCC-SD/JIS G3141) with varying thicknesses of 0.6 mm and 0.8 mm. Automobile bodies commonly utilize mild steel with a material thickness ranging from 0.6 to 0.98 mm. The objective of this study was to ascertain the upper limit of tensile-shear strength that can be achieved by utilizing the specific parameters utilized in TIG welding. This study utilizes a three-level experiment and incorporates three input variables in the Taguchi experimental optimization method. The advantage of this approach lies in its ability to yield comprehensive outcomes while minimizing expenses, as it can be adapted to the resources available. An additional benefit is that this approach can be implemented in a multitude of industrial situations.The study's input variables are welding current, argon gas flow rate, and electrode diameter. Utilizing a continuous flow of argon gas of 12 LPM (liter per minute), a welding current of 55 A, and an electrode diameter of 1.6 mm, the maximum mean T-S strength of 3457.13 N was achieved. The ANOVA revealed that the flow rate, welding current, and electrode diameter had a per cent contribution of 50.07%, 26.89%, and 23.04%. The flow rate was the parameter with the most significant impact on the influential variable. The welding current and the electrode diameter do not significantly affect the response. The findings indicate that by adjusting the parameters to the optimal level determined by the Taguchi method, the S-N ratio for T-S strength increases by 9.30%, and T-S strength increases by 12.42%. The findings of this study offer a thorough comprehension of enhancing the TIG welding approach and can be further refined by incorporating additional variables.

Abstract

Proyek konstruksi sering mengalami kinerja yang buruk dalam hal keterlambatan waktu sehingga keterlambatan adalah hal yang paling umum, mahal, rumit dan berisiko. Ketika keterlambatan terjadi pada proyek dapat menyebabkan kerugian berbagai pihak seperti pihak pemilik (dalam hal kinerja) dan kontraktor (dalam hal uang). Dalam pelaksanaan proyek konstruksi hunian tetap ini ini menghadapi beberapa kendala yang menyebabkan keterlambatan. Adapun penelitian ini adalah untuk mengidentifikasi risiko keterlambatan, mengetahui risiko keterlambatan yang dominan, serta melakukan penanganan terhadap risiko yang dominan. Metode Penelitian ini akan dilakukan dengan survey, wawancara dan menyebarkan kuesioner kepada 32 responden. Analisis data kuesioner ini akan diolah dengan software SPSS untuk menguji validitas dan realibilitas data. Setelah itu akan dilakukan analisis faktor-faktor yang mempengaruhi keterlambatan pembangunan hunian tetap di Kab.Donggala kemudian dilakukan analisis mitigasi keterlambatan pembangunan tersebut. Dari hasil analisis diperoleh 3 variabel risiko yang paling dominan yang mempengaruhi keterlambatan pada proyek huntap, yaitu: X2 material dan peralatan, X6 pembiayaan dan X1 aspek perencanaan pekerjaan.

Abstract

Salah satu penyebab stunting adalah kurangnya kualitas air yang aman untuk dikonsumsi. Kegiatan pengabdian ini berfokus pada pelatihan instalasi penjernihan air menggunakan sistem Reverse Osmosis (RO) sebagai upaya untuk mengurangi prevalensi stunting di desa Simoro, kabupaten Sigi. Teknologi RO mampu menyaring kontaminan berbahaya dari air, sehingga menghasilkan air bersih yang aman untuk diminum. Pelatihan ini bertujuan untuk meningkatkan akses air bersih, memberikan pemahaman teknis mengenai instalasi dan pemeliharaan sistem RO, serta mendorong masyarakat untuk memanfaatkan teknologi ini sebagai peluang usaha. Dengan pelatihan ini, diharapkan peserta mampu menyediakan air minum yang berkualitas, yang pada gilirannya akan berkontribusi dalam mengurangi risiko penyakit dan stunting, serta meningkatkan kemandirian ekonomi melalui usaha air minum bersih
