Concordance of dynamic fractional inequalities interconnected on time scales

In this work, we present an extension of dynamic reverse Minkowski’s inequality by using the time scale Riemann–Liouville type fractional integrals. By using the definitions of delta and nabla time scales Riemann–Liouville type fractional integral operators, we find other general dynamic fractional inequalities. Our findings unify and extend some continuous, discrete and quantum analogues.Publisher's Versio

Transfer Control of Public Housing Ownership in Indonesia

Introduction to The Problem: Resettlement/Shelter is one of the basic human needs and plays a strategic role as the formation of character as well as national personality. However, there is still a problem concerning the availability of public housing in Indonesia. The root of this problem is because people are free to transfer their ownership over their public housing, which leads to the escalation of public housing price. One of the situations where an escalation of public housing price occurred and inaccurate-ownership is in Kalibata City. Kalibata City was supposed to be public housing, but in the present, it 3is occupied by upper-middle-income families as well as an investor.Purpose/Objective Study: The purpose of this research article is to observe, analyze, and criticize the transfer of public housing ownership in Indonesia and provide a comparison with the Community Land Trust in the United States of America.Design/Methodology/Approach: The research method employed in this research article is normative research method, whereas the types of data utilized are literature studies. The literature studies comprise of various sources in the form of laws, books, and journals related to public housing. The data is analyzed by employing a qualitative method and presented descriptively.Findings: The result of this research article indicates that the Government Regulation which is a follow-up to Article 55 paragraph (5) Law Number 1 of 2011 regarding Housing and Resettlement Area which mandates to regulate further related to the appointment and establishment of the institution has not been formed yet. Furthermore, to realize intergenerational justice, the transfer institution must be burdened with specific duties

ANALISIS DAMPAK KETERLAMBATAN SUB-SUB PEKERJAAN STRUKTUR ATAS TERHADAP JADWAL PEKERJAAN STRUKTUR ATAS

Pekerjaan struktur bangunan gedung dibagi menjadi struktur atas dan struktur bawah. Struktur atas yang dimaksud adalah struktur bangunan yang berada di atas permukaan tanah, sedangkan struktur bawah yang dimaksud adalah struktur bangunan yang berada di bawah permukaan tanah. Penelitian ini bertujuan untuk mengetahui faktor – faktor teknis dominan yang mengakibatkan keterlambatan pekerjaan struktur atas. Penelitian dilakukan untuk mengetahui besarnya dampak yang ditimbulkan akibat keterlambatan pekerjaan struktur atas. Penelitian ini juga bertujuan untuk mengetahui faktor utama yang menjadi penyebab keterlambatan pekerjaan struktur atas. Metode penelitian yang digunakan merupakan metode penelitian deskriptif. Pengumpulan data dilakukan dengan menyebaran angket (kuesioner) untuk identifikasi faktor dominan dan dampak keterlambatan yang timbul pada pihak kontraktor proyek. Analisis penelitian menggunakan metode AHP (Analisis Hirarki Proses) untuk menentukan peringkat faktor yang dominan dan metode PCA (Principal Component Analysis) untuk mengetahui faktor utama penyebab keteerlambatan. Hasil penelitian menunjukkan kesalahan dimensi kolom menjadi faktor yang paling dominan dengan dampak sangat tinggi terhadap jadwal pelaksanaan pekerjaan struktur atas gedung. Dampak yang ditimbulkan jika terjadi kesalahan dimensi kolom akan mengakibatkan proyek pada posisi kritis. Terdapat dua kelompok faktor yang menjadi penyebab utama keterlambatan struktur atas. Building structure work is divided into upper structure and lower structure. The upper structure meant is the structure of the building that is above the ground surface, while the lower structure is the structure of the building that is below the soil surface. This study aims to determine the dominant technical factors that result in delays in the work of the upper structure. The research was conducted to of the impact caused by delays in the work of the upper structure. This study also aims to find out the main factors that cause job delays in the upper structure. The research method used is descriptive research method. Data collection was carried out by distributing questionnaires to identify dominant factors and the impact of delays arising on the project main contractor. Research analysis uses the AHP method (Analysis Hierarchy Process) to determine the dominant factor ranking and the PCA (Principal Component Analysis) method to determine the main factors causing the delay. The results of the study show that column dimension error is the most dominant factor with very high impact on the work schedule of building structures. The impact caused if an error occurs in the column dimension will result in the project in a critical position. There are two groups of factors which are the main causes of the upper structure delays

Sintesis hidroksiapatit dari limbah cangkang telur ayam dengan metode presipitasi kimia sebagai adsorben ion logam tembaga(II)

INDONESIA : Limbah cangkang telur ayam dapat didaur ulang menjadi adsorben hidroksiapatit karena mengandung kalsium yang tinggi. Hidroksiapatit dapat digunakan sebagai adsorben karena memiliki pori-pori, kapasitas penyerapan tinggi, kelarutan air rendah, laju degradasi yang rendah, non-toksik, serta stabilitas tinggi dalam kondisi reduksi dan oksidasi. Adsorbat yang dapat diserap yaitu logam berat, salah satunya ion logam tembaga(II). Reaksi yang terjadi antara adsorben dengan adsorbat adalah reaksi pertukaran ion yang terjadi antara anion pada hidroksiapatit dengan kation pada logam tembaga(II). Pada penelitian ini dilakukan sintesis dan karakterisasi hidroksiapatit dari limbah cangkang telur ayam dengan metode presipitasi kimia kemudian diaplikasikan ke dalam ion logam tembaga(II). Metode presipitasi kimia ini menggunakan Ca(NO3)2, (NH4)2HPO4, dan NH4OH sebagai prekursor. Ca(NO3)2 didapatkan dengan melarutkan CaCO3 pada cangkang telur ayam. Karakterisasi yang dilakukan yaitu XRD, SEM-EDS, dan FTIR. Hasil karakterisasi menunjukkan bentuk kristalin, terdapat aglomerasi, pori-pori, serta terbentuk gugus fungsi penyusun hidroksiapatit. Hasil penelitian menunjukkan senyawa hidroksiapatit hasil sintesis dari limbah cangkang telur ayam dengan metode presipitasi kimia merupakan adsorben yang baik dalam menyerap ion logam tembaga(II). Hal ini dibuktikan dengan hasil adsorben menjerap adsorbat pada kondisi optimum yaitu pada 70 ppm selama 75 menit dengan menggunakan 0,1 gram sampel dan 75 mL larutan serta efisiensi rata-rata yaitu 88,142%. Hasil isoterm adsorpsi menunjukkan model Langmuir dengan adsorpsi kimia (kemisorpsi). ENGLISH : Chicken eggshell waste can be recycled into hydroxyapatite adsorbent because it contains high calcium. Hydroxyapatite can be used as an adsorbent because it has pores, high adsorption capacity, low water solubility, low degradation rate, non- toxicity, and high stability in reduction and oxidation conditions. The adsorbate that can be absorbed is heavy metals, one of which is copper(II) metal ions. The absorption reaction between the adsorbent and the adsorbate is an ion exchange reaction that occurs between anions in hydroxyapatite and cations in copper(II) meta ionsl. In this study, the synthesis and characterization of hydroxyapatite from chicken eggshell waste was carried out by chemical precipitation method and then applied to copper(II) metal ions. This chemical precipitation method uses Ca(NO3)2, (NH4)2HPO4, and NH4OH as precursors. Ca(NO3)2 is obtained by dissolving CaCO3 in chicken egg shells. The characterizations carried out are XRD, SEM-EDS, and FTIR. The characterization results showed a crystalline form, there was agglomeration, pores, and the formation of a functional group as a constituent of hydroxyapatite. The results showed that the hydroxyapatite compound synthesized from chicken egg shell waste by chemical precipitation method was a good adsorbent for absorbing copper(II) metal ions. This is evidenced by the results of the adsorbent absorbing the adsorbate at the optimum condition, namely at 70 ppm for 75 minutes using 0.1 gram sample and 75 mL solution and the average efficiency is 88.142%. The results of the adsorption isotherm showed the Langmuir model with chemical adsorption (chemisorption)
