Abstract

Striped catfish is one of the leading sectors in aquaculture in Banjar Regency, it is stated in the Decree of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number. KEP.32/MEN/2010 and the Decree of the Banjar Regency Number. 241 of 2008 about the Stipulation of Striped Catfish Cultivation Fisheries Areas. Until this time, striped catfish production is mostly sold in fresh form in traditional markets from South Kalimantan to Central Kalimantan and East Kalimantan. Whereas striped catfish can be processed into various varied and productive forms because it has a rich taste, colored meat with a chewy texture, highly nutritious and affordable prices. To increase the utilization of striped catfish, it is necessary to have processed products in order to increase the income of the surrounding community. The Community Partnership Program activity aims to transfer community technology through training in processing various foods made from striped catfish. The method consists of (a) counseling and (b) practical demonstration which aims to provide knowledge and skills to the target audience, which are the communities around the striped catfish minapolitan in Bincau Village, Martapura District, Banjar Regency. The continuance from the training results of this activity is to increase community skills in processing catfish-based products which leads to improvements in the household economic sector through economic growth and increasing incomes of the surrounding community.

Abstract

Water is a very important daily need in human life. Water is needed for drinking, preparing food, washing and cleaning. The water used must be suitable for use with quality according to physical, biological and chemical parameters. The aim of this study is to design an instrument for water turbidity which is a one of physical parameter. Turbidity occurs due to the scattering of particles that affect the absorption of light rays in water, such as sediment. Feasible water has a turbidity value of 25 NTU. The tool for measuring water turbidity uses a turbidity sensor SKU: SEN0189 which has been integrated with the Arduino Uno R3 microcontroller and can store measurement results automatically through the Delphi 7.0 interface software in .xls format. This water turbidity measuring instrument can be applied with a smart water tool, so that the percentage value of the decrease in the level of turbidity of water that has been carried out by the filtration process can be known. The test results of the water turbidity measuring instrument showed that turbidity ≤452 NTU had a standard deviation value of ±2 NTU and turbidity ≥520 NTU had a standard deviation value of ±1. The implementation of a river water turbidity measuring instrument using a SKU:SEN0189 turbidity sensor has been carried out in Martapura river water with 3 different location points. The measurement results before filtration show that the highest turbidity value is 124 NTU at point 1, 130 NTU at point 2, and 189 NTU at point 3. In the measurement after filtration, the smallest turbidity value is 9 NTU at point 1, 9 NTU at point 2, and 13 NTU at point 3. This shows that after the filtration process of Martapura river water has been carried out with a smart water tool, Martapura river water can be used for sanitary hygiene purposes according to the water turbidity parameter with a value below the 25 NTU threshold.

Abstract

PET (Positron-emission tomography) is used to determine physiological and metabolic functions in the body. Monte Carlo simulation is an important part of PET imaging, and the Particle Heavy Ion Transport code System (PHITS) is a simulation platform that can be used to perform Monte Carlo simulations. This study uses a Monte Carlo simulation based on PHITS to determine the range of gamma absorption with an energy of 511 keV in a scintillation detector crystal material. The gamma absorption range determines the effective crystal length in the PET modality. The simulation process is carried out by shooting Gamma at various types of materials, which are the materials used in PET scintillation crystals. The materials used in this simulation are NaI (Sodium Iodide), BaF2 (Barium Florida), BGO (Bismuth Germanate), and GSO (Gadolinium Oxyorthosilicate), considering their atomic number and crystal density. The crystal material is capable of absorbing gamma radiation with an energy of 511 keV with detailed crystal lengths for each NaI crystal of 0.26 cm; 0.25 cm BaF2 crystals; 0.1cm BGO crystals; and 0.18 cm GSO crystals. The crystal length from this simulation is smaller than the commercially available crystal length (range 1-3 cm). Based on the crystal length data, the most effective crystal for absorbing gamma radiation is the BGO crystal.

Abstract

Telah dilakukan penelitian penentuan karakteristik akustik interior ruangan menggunakan Metode Elemen Batas (Boudary Element Method, BEM). Model ruang/ objek yang digunakan berbentuk persegi berukuran 18 m x 8 m x 3,5 m dengan asumsi permukaan rigid (keras). Ruang objek didiskritisasi menjadi 56 elemen dan 170 node. BEM merupakan salah satu metode untuk menyelesaikan masalah-masalah numerik. BEM memiliki keunggulan utama yaitu hanya permukaan sumber akustik yang didiskritisasi sehingga mengurangi dimensi persoalan yang dipecahkan, menghemat waktu komputasi dan akurasi yang lebih baik. Penelitian ini bertujuan menentukan karakteristik akustik dalam domain interior yaitu tekanan akustik dan kecepatan potensial yang kemudian divisualisasikan menggunakan software MATLAB. Ada empat kasus yang akan diuji yaitu, pertama semua sumber suara ada pada permukaan ruangan, kedua sumber suara berasal dari dua buah loudspeaker, ketiga sumber suara berasal dari satu buah loudspeaker dan keempat sumber suara berasal dari dua buah loudspeaker dengan dua buah bidang permukaan diberi bahan penyerap. Hasilnya menunjukkan nilai minimum dan maksimum tekanan pada titik medan (field point) kasus pertama, kedua, ketiga dan keempat masing-masing adalah 31,768 Pa dan 1664,600 Pa; 0,019 Pa dan 1,278 Pa; 0,018 Pa dan 1,742 Pa; 0,028 Pa dan 1,283 Pa. Waktu dengung yang diperlukan pada kasus pertama, kedua, ketiga dan keempat berturut-turut adalah 1,06 detik, 1,25 detik, 1,27 detik dan 0,7 detik. Waktu dengung pada kasus keempat lebih kecil dibandingkan pada kasus kedua dengan selisih 0,55 detik (sama-sama diberi perlakuan yang sama akan tetapi pada kasus keempat diberi bahan penyerap). Hal ini memperlihatkan bahwa dua buah sumber bunyi dengan kekuatan sama dapat menyebabkan waktu dengung yang berbeda bila bahan permukaan ruangan diganti dengan bahan yang mempunyai koefisien serapan tertentu. Selain itu, didapatkan pengurangan kebisingan pada kasus keempat sebesar 2,5 dB.
