Abstract

In industrial processing, side products are produced in the form of liquid waste containing heavy metals, including Cr (III) which can have a negative impact on the environment. Some egg shell characteristics containing  high concentrations of CaCO3 and have a natural pore structure can be used as adsorbers (biosorbents) of heavy metals produced by the processing industry. The purpose of this study was to obtain the optimum conditions of absorption (adsorption) of Cr (III) metals carried out by egg shell biosorbents. The research method was carried out experimentally which included the preparation of egg shell waste biosorbents, determining the optimum time, as much as 1.0 gram of eggshell biorsorbent was put into 25 ml of heavy metal waste solution with a concentration of 50 ppm, then adsorption was carried out with time variations of 5, 10, 20 , 30, 40, 50, 60 and 120 minutes. Variation of  Cr concentration  were 50,0 ppm; 100,0 ppm,  150,0 ppm; 200,0 ppm; 250,0 ppm; 300,0 ppm; 350,0 ppm, 400,0 ppm; 450,0 ppm; 500,0 ppm; dan 1000 ppm. After that the mixture is filtered and the filtrate is read on the Atomic Absorption Spectrophotometer (AAS) to find out the maximum adsorption. The results showed the optimum conditions of adsorption of Cr (III) metals obtained an optimum time of 40 minutes with an absorption capacity of 1242.46 µg Cr (III) / g biosorbent, and optimum concentration with optimum treatment time and weight at 200 ppm with an absorption capacity of 4984 , 99 µg Cr (III)/g biosorbent. The adsorption isotherm adopts the Freundlich isotherm or physically (physical) type, because the linearity of the Freundlich isotherm obtained from the calculation results is R2 = 0.7312 or 73.12% higher than the Langmuir isotherm ie R2 = 0.0335 or 3.35%.  Keyword : Cr (III) heavy metal, eggshell biosorbent, optimum adsorption conditions

Abstract

The construction project is assessed based on the realization of the construction according to the quality, time and cost in the planning document. To monitor implementation, a scheduling method is needed that can describe the relationship between activities and implementation time, so that the work can be completed according to the target duration specified in the construction contract. Two methods are known in scheduling critical paths, namely Activity On Arrow (AOA) and Activity On Node (AON) where AOA is more widely used in projects, whereas AON has the advantage of 4 relationships between activities with activity symbols on the box, while AOA is only 1 type with symbol of the activity on the arrow. The purpose of this study is to obtain the benefits of using AON rather than AOA by scheduling using the two methods on the schedule of the construction of a high-rise building in Banten, using Microsoft Project (MS Project) software, and analyzing the differences. In MS Project AOA is known as the Activity Diagram Method and AON with the Precedence Diagram Method. From the comparative analysis results obtained that with AOA obtained 74 activities and 48 activities with AON with the same duration and critical activities in both methods. The AON diagram can better illustrate the relationship between activities that are simpler and simpler with a total efficiency of 35%.

Abstract

Currently the industry is trying to improve its competitiveness. This makes the manufacturingindustry needs to adapt the Lean-Kaizen concept. Lean-Kaizen means eliminating waste through small improvements made on an ongoing basis. This research takes a case study at PT Inoac Poltechno Indonesia, which is engaged in foam production. The current production target is only 56% of the planned target. Besides that, there are found many defective products and activities that have no added value. Furthermore, a map of the current condition is made to find waste and know the kaizen that will be carried out. Furthermore, a future map was developed with work standardization and Value Stream Mapping to determine activities that have no added value. Calculation of Waste Assessment Model (WAM), shows the biggest waste is defect (26.73%), inventory (15.79%), and waiting (13.35%). This study found that by adding trolley, adding operators, making SOPs, scheduling engine maintenance would make non-value added (NVA) activities decrease from 29.95% to 20.5%. Process Cycle Efficiency increased from 22.31% to 28.25% (thus fulfilling international PCE requirements for the manufacturing industry). Keyword : Lean-Kaizen, productivity, waste

Abstract

Improvement of Textile Industry system design with Six Sigma and FMEA to improve process quality. Six Sigma is a method of continuous quality improvement, by minimizing the number of defects. FMEA (Failure Mode Effect Analysis) tool is used to help determine the appropriate action, eliminating priority failure modes. The next step to improve to determine the most influential factor to the occurrence of color defects, so that the influence of the interference factor is minimum. If the control function is carried out and the factors causing the defect do not appear again there will be an increase in sigma value. FMEA analysis results obtained by machine temperature and material factors that most influence the occurrence of color defects, with RPN values of 210 and 120 respectively, the Six Sigma calculation results an increase in sigma value from initial conditions of 3.78 sigma to 4.93 sigma, or an increase in process capability of 1.15 sigma. Proposed improvements with DOE so that color defects do not appear are suggested by setting the thermosol engine temperature control device and mixing the optimized NaCl.

Abstract

For beginners, to start investing should have careful consideration. Investment objectives, time period, risk are things that must be considered, and the most important is what investment instruments are suitable and we will choose later, of course, to achieve the objectives of the investment itself, namely future profits. Some investment instruments that have the advantages that have been summarized by the Indonesia Stock Exchange as of December 29, 2017 include, Savings (2.53%), government bonds (8.96%), gold (7.30%), deposits (7.36) %), and shares (13.13%).Technical and fundamental analysis are two analyzes that are often used to analyze stock movements. Technical analysis is an analysis that predicts future stock prices using historical prices. Whereas fundamental analysis is an analysis that uses information inside and outside the company, such as performance, business competitors, industry and even micro-macroeconomics, as well as market information. Fundamental analysis is generally used by long-term investors, so the sustainability of the company is a very important consideration.Common indicators in Fundamental Analysis are EPS (Earning Per Share), PER (Price Earning ratio), PBV (Price Book Value), ROE (Return of Equity), Dividend Yield, and DER (Debt Earning Ratio). From the fundamental analysis using the 2019 financial statements of food and beverage sector companies in LQ45 with EPS, PER, PBV, ROE, DY, and DER indicators the best performance is on UNVR company shares, because almost all indicators occupy good positions except DER indicators because UNVR has a high DER, then followed by JPFA, ICBP, and INDF.

Abstract

Usaha Mikro, Kecil dan Menengah (UMKM) merupakan penggerak perekonomian Indonesia yang memiliki potensi yang besar, guna meningkatkan ekonomi dan kesejahteraan masyarakat. Namun berdasarkan wawancara terhadap pakar , pendamping dan pelaku UMKM, untuk memaksimalkan potensi tersebut masih banyak masalah di lapangan yang perlu diperbaiki. Oleh sebab itu, rumusan masalah pada penelitian ini adalah hal apa saja yang masalah utama yang terjadi pada UMKM di Tangerang Selatan dan strategi apa yang dapat dilakukan untuk pengembangan UMKM Tangerang Selatan. Sehingga tujuan penelitian ini adalah merumuskan alternatif kebijakan pengembangan UMKM di Tangerang Selatan dengan pendekatan SSM. Penelitian ini menggunakan pendekatan soft system methodology (SSM), dimana inti proses pendekatan metode SSM adalah membandingkan antara kondisi nyata yang ada dengan kondisi model yang seharusnya terjadi, sehingga menghasilkan pemahaman lebih baik atas kondisi yang dijadikan objek penelitian. Dari hasil analisa perbandingan terhadap model konseptual dengan model dunia nyata (aktual), dapat disimpulkan bahwa masalah utama yang dihadapi UMKM adalah masih terdapat gap yang besar antara kondisi ideal yang diharapkan dengan kondisi nyata. Strategi yang perlu dilakukan adalah 1.Akademisi perlu mengarahkan risetnya ke riset terapan yang dibutuhkan UMKM/ industri, pengabdian masyarakat yang bersifat insidentil perlu diarahkan menjadi tematik berkelanjutan. 2. Perbankan perlu memberikan pinjaman ringan khusus bagi para UMKM baik dari segi persyaratan maupun suku bunga. 3.Bantuan pemerintah tidak bersifat sepotong-sepotong tidak saling terkait dan pelatihan yang bersifat proyek, tapi perlu pendampingan, yang berkelanjutan. 4.UMKM perlu didorong untuk memiliki jaringan dan motivasi yang kuat hingga mampu bertahan dan menjawab setiap tantangan. 5.UMKM perlu dibantu untuk mampu memenuhi hak konsumen yang sering kali diabaikan, sehingga mampu membangun kepercayaan dan loyalitas pelanggan.

Abstract

Abstract A mixed use area is basically an urban area that is designed in an integrated manner (integrated development), with a fairly high building density and a combination of land functions that are mixed (mixed used), where the most important key to its success is the functioning of the control mechanism which is the implementation. from the regulations for the development of the superblock area itself (Wikipedia, 2018). Another definition based on arsitag.com states that Mixed use is the use of a building, a building complex, or an environment for more than one use. This concept has been adopted by several countries in the world since 1920. The idea is to combine offices, residences, and other activity centers in adjacent areas or even in the same building. In Indonesia, mixed areas are permitted and regulated in Government Regulation Number 15 of 2010 concerning Spatial Planning, which mandates that to improve the quality of spatial structures and spatial patterns. In addition, in the Regulation of the Minister of ATR / BPN Number 16 of 2017 concerning Guidelines for the Development of Transit Oriented Areas, Regulation of the Minister of ATR / BPN Number 1 of 2018 concerning the Compilation of Regional Spatial Planning (RTRW), and Regulation of the Minister of ATR / BPN Number 16 of 2018 concerning Compilation Detailed Spatial Planning (RDTR) and Zoning Regulations (PZ. In the spatial planning regulations, the mixed area is regulated in a mixed zone (C), which includes; housing and trade / services, housing and offices, trade / services and offices. For the use of the mixed zone category, it must be supported by the existence of a clear zone boundary which can limit the further expansion of the mixed function and there must be an effort to encourage the development of the mixed function towards a certain designated zone. Therefore, it is necessary to conduct this research to provide input and suggestions for related parties, including mixed area typology, mixed area prerequisites, mixed area principles, mixed area criteria and standards.

Abstract

Rumah tinggal peninggalan Raden Aria Wangsakara yang berlokasi di permukiman Lengkong, Tangerang, Banten merupakan salah satu bangunan bersejarah yang telah ditetapkan sebagai bangunan cagar budaya. Namun, seiring dengan gencarnya aktivitas pembangunan kota untuk meningkatkan nilai kawasan, terutama yang terjadi di Lengkong, hal ini berpotensi menggerus dan menghilangnya bukti sejarah serta nilai-nilai budaya kawasan tersebut apabila tidak adanya upaya pelestarian yang lebih lanjut. Penelitian terdahulu terhadap Rumah Arya Wangsakara telah lebih banyak dilakukan pada lingkup yang makro, yaitu obyek bangunan yang dikaitkan dengan konteks sejarah dan geografis kawasan. Sementara itu, dalam upaya pelestarian yang lebih teknis pada bangunan, pengetahuan membangun bangunan belum banyak dibahas. Padahal, langkah ini sangat diperlukan untuk mengetahui nilai-nilai budaya yang terkandung pada bangunan rumah Raden Aria Wangsakara melalui tipologi arsitektur bangunannya dan menentukan signifikansi bangunan yang berkontribusi untuk meluaskan khasanah arsitektur dan ketukangan. Untuk itu, langkah penelitian ini, yaitu menguraikan kesejarahan bangunan cagar budaya rumah Raden Aria Wangsakara, mengidentifikasi tipologi bangunan cagar budaya rumah Raden Aria Wangsakara melalui elemen-elemen arsitekturnya, dan menganalisa elemen-elemen arsitektural bangunan sekitar bangunan cagar budaya rumah Raden Aria Wangsakara. Hasil penelitian ini diharapkan dapat bermanfaat bagi peningkatan nilai sejarah dan budaya bangunan serta kawasan, dokumentasi catatan ketukangan, dan menginspirasi masyarakat untuk mengekspresikan upaya pelestarian melalui elemen arsitektural yang diterapkan pada bangunan atau kawasan sekitar mereka.
