Abstract

This study was aimed to know the effect of B2O3(boria) addition on the phase composition and physical properties of zircon ceramics.The raw zircon powder used in the study was a purified natural zircon sand from Kereng Pangi, Central Kalimantan, Indonesia. The zircon ceramics were prepared by a solid state reaction method with variation of B2O3 addition of 3 wt%, 6 wt% and 9 wt% and sintered at 1300 °C for 5h. The phase composition, density and microstructure were characterized using X-ray diffraction (XRD), densimeter and Scanning Electron Microscope (SEM), respectively. Vickers Hardness measurement was perfomed at the polished surface of the ceramics. Results showed that all samples contained pure zircon phase, i.e. there was no effect of B2O3 addition on the phase composition. In general, the density and hardness increased with increasing B2O3 addition, but addition up to 9 wt% is not optimum to achieve ultra-dense zircon ceramics. Furthermore, the SEM image also showed no significant difference in average grain size. The crystallite size has grown nearly eight times (325 nm) of its original powder. The Vickers hardness of the ceramics is not significantly influenced by the addition of boria. It appears that the boria failure to increase densification also results in the extent of contact between grains which then produces relatively large zircon grains.

Abstract

This study investigated the effect of calcination temperature on the phase composition and crystal size of zinc oxide powders synthesised by the sol-gel method. Zn powder, HCl and NaOH were used as precursors in a multi-step process involving dissolution, titration, gel formation, leaching, drying and calcination at temperatures ranging from 300°C to 700°C for 2 hours. Rietveld analysis of X-ray diffraction (XRD) data using MAUD and Rietica software determined phase composition and crystal size. Initial analysis identified a single simonkolleite phase (Zn5(OH)8Cl2) prior to calcination, which disappeared at 500°C. Wurtzite (ZnO) appeared at 300°C, accompanied by secondary phases (NaCl and ZnCl2). The wurtzite content increased to 81.42 wt% at 700°C. Calcination temperature also influenced crystal size, which ranged from 27.34 nm to 110.61 nm for wurtzite at different temperatures. The results highlight the dynamic changes in phase composition and crystal size with different calcination temperatures, providing valuable insights into tailoring zinc oxide properties for various applications.

Abstract

Abstrak Survei awal di Jalan Soekarno Hatta KM. 15 RT. 32 Kampung Banyumas, Kelurahan Karang Joang, Balikpapan mengidentifikasi dua permasalahan utama, yaitu keterbatasan pasokan air bersih dan jumlah volume air tergenang yang dihasilkan dari air sumur bor. Kegiatan pengabdian masyarakat di RT 32 Kelurahan Karangjoang, khususnya di Gang Sayudi, bertujuan untuk meningkatkan akses masyarakat terhadap air bersih melalui pendampingan pembuatan biopori dan filtrasi air tanah. Metode pelaksanaan melibatkan pertemuan dengan masyarakat, pelatihan langsung, dan sosialisasi rutin. Kegiatan meliputi pelatihan dan penyuluhan, praktik langsung di lapangan membuat biopori dan sistem filtrasi air tanah, serta monitoring untuk mengukur keberhasilan dan efektivitas sistem. Pembuatan biopori memanfaatkan sampah daun serta sampah organik basah dari limbah rumah tangga di Kampung Banyumas. Hasil menunjukkan peningkatan infiltrasi air ke dalam tanah, pengurangan limbah organik, dan peningkatan kualitas air. Sistem filter yang terdiri dari saringan, karbon aktif, mangan zeolit, pasir silika, dan kerikil efektif dalam mengurangi kekeruhan, zat padat terlarut, dan kandungan besi dan mangan. Melalui rangkaian kegiatan ini, diharapkan dapat memberikan solusi komprehensif bagi permasalahan yang teridentifikasi dan memberikan dampak positif bagi masyarakat di Kampung Banyumas, Balikpapan, dengan mendukung praktik pengelolaan sampah yang lebih ramah lingkungan. Kata kunci: filter air; biopori; air tanah; air bersih. AbstractInitial survey on Jalan Soekarno Hatta KM. 15 RT. 32 Kampung Banyumas, Kelurahan Karang Joang, Balikpapan identified two main problems, namely limited clean water supply and the volume of stagnant water produced from drilled well water. Community service activities in RT 32 Kelurahan Karangjoang, especially in Gang Sayudi, aim to improve community access to clean water through assistance in making biopores and groundwater filtration. The implementation method involves meetings with the community, direct training, and routine socialization. Activities include training and counseling, direct practice in the field in making biopores and groundwater filtration systems, and monitoring to measure the success and effectiveness of the system. The creation of biopores utilizes leaf waste and wet organic waste from household waste in Kampung Banyumas. The results showed increased water infiltration into the soil, reduced organic waste, and improved water quality. The filter system consisting of filters, activated carbon, manganese zeolite, silica sand, and gravel is effective in reducing turbidity, dissolved solids, and iron and manganese content. Through this series of activities, it is hoped that it can provide a comprehensive solution to the identified problems and provide a positive impact on the community in Kampung Banyumas, Balikpapan, by supporting more environmentally friendly waste management practices. Keywords: water filter; biopore; groundwater; clean water.

Abstract

Abstrak Cultural Camp merupakan salah satu program pengabdian masyarakat yang dijalankan di Institut Teknologi Kalimantan (ITK), yang bertujuan untuk memberikan pemahaman mendalam tentang kekayaan budaya Indonesia kepada mahasiswa asing dan lokal. Dengan tema "Ibu Kota Nusantara (IKN): A City for All," program ini menargetkan pembentukan generasi mahasiswa yang menghargai perbedaan budaya dan mampu berkontribusi dalam melestarikan warisan budaya Indonesia. Sejumlah 30 peserta dari Perancis, Denmark, Jerman, China, Malaysia, dan mahasiswa lokal mengikuti kegiatan ini. Peserta mengikuti rangkaian aktivitas mulai dari short course tentang IKN, pelatihan membatik, mencicipi santapan khas daerah, hingga campus tour, jalan santai ke Kebun Raya Balikpapan, dan kunjungan ke kampung adat Dayak. Metode deskriptif kualitatif digunakan dalam kegiatan ini, dengan pengumpulan informasi melalui pengamatan, dokumentasi, dan wawancara untuk memahami pengalaman peserta selama Cultural Camp. Interaksi antara peserta dari berbagai latar belakang budaya menguatkan keterlibatan dan pemahaman antarbudaya, menciptakan ikatan peserta dan masyarakat lokal, meningkatkan komitmen bersama dalam mendukung dan memperkaya satu sama lain dalam perjalanan lintas budaya. Kata kunci: cultural camp; budaya; ibu kota nusantara; kalimantan; dayak. Abstract Cultural Camp is one of the community service programs run at Institut Teknologi Kalimantan (ITK), which aims to provide an in-depth understanding of the richness of Indonesian culture to foreign and local students. With the theme " Ibu Kota Nusantara (IKN): A City for All," this program targets the formation of a generation of students who respect cultural differences and are able to contribute to preserving Indonesia's cultural heritage. 30 participants from France, Denmark, Germany, China, Malaysia and local students took part in this activity. They took part in a series of activities ranging from a short course on IKN, batik training, tasting regional specialties, to a campus tour, a leisurely walk to the Balikpapan Botanical Gardens, and a visit to a Dayak traditional village. A qualitative descriptive method was used in this activity, by collecting information through observation, documentation and interviews to understand the participants' experiences during the Cultural Camp. Interaction between participants from various cultural backgrounds strengthens intercultural engagement and understanding, creates bonds between participants and local communities, increasing mutual commitment in supporting and enriching each other in cross-cultural travel. Keywords: cultural camp; culture; ibu kota nusantara; kalimantan; dayak.
