Abstract

In this study, low-cost sensors for air quality monitoring system have been characterized and designed. These sensors are applied in a monitoring system and installed at Sriwijaya University, which is vulnerable to the impacts of forest fires in the surrounding area. This monitoring system will provide information especially for the university community to determine the level of air quality on campus. In this research the researchers focussed on the characterization and design of system sensor that aimed to get the best configuration of low-cost sensors namely MQ-7, Sharp GP2Y1010AU0F and own-designed smoke sensor to have high reliability and effectiveness to be applied to monitoring systems. The test results showed that the sensors have good response and sensitivity. Therefore, it can be applied to the monitoring system to provide information about the level of particle concentration, carbon monoxide and smoke which meet the needs of low-cost monitoring systems.

Abstract

ABSTRAKKampung Adat Cireundeu merupakan salah satu wilayah industri Kota Cimahi yang masih mempertahankan kegiatan pertanian. Keunggulan daerah (comparative advantage) yang dimiliki meningkatkan potensi Kampung Adat Cireundeu mengembangkan agribisnis singkong melalui penerapan agroindustri dan agrowisata berbasis kearifan lokal. Jumlah pengunjung yang masih sedikit dan fluktuatif akan menentukan jumlah permintaan produk agroindustri singkong karena sebagian besar konsumen merupakan pengunjung Kampung Adat Cireundeu. Tujuan penelitian ini adalah mengetahui adanya keterkaitan antara agroindustri singkong dan agrowisata di Kampung Adat Cireundeu, dan mengetahui strategi yang tepat untuk pengembangan agribisnis di Kampung Adat Cireundeu berbasis kearifan lokal. Metode yang digunakan adalah studi kasus dengan melakukan analisis deskriptif kualitatif pada 37 responden dengan alat analisis yang terdiri dari persepsi pengunjung, WTP, IFE, EFE, dan SWOT. Hasil dari penelitian ini menunjukkan bahwa adanya keterkaitan antara agroindustri singkong dan agrowisata di Kampung Adat Cireundeu dengan posisi strategi pada kuadran 3 sehingga Kampung Adat Cireundeu perlu melakukan diversifikasi strategi. Strategi yang tepat untuk pengembangan agribisnis singkong di Kampung Adat Cireundeu berbasis kearifan lokal, yaitu 1) Memperkenalkan produk melalui media berupa brosur yang diberikan kepada konsumen yang pernah datang, 2) Mendirikan restoran yang bernuansa Kampung Adat Cireundeu, dan 3) Memperbanyak saluran pemasaran agar jaringan hubungan konsumen semakin luas. Kata kunci: Agroindustri, Agrowisata, Analisis Persepsi Pengunjung, WTP, dan SWOT.  STUDY OF LOCAL WISDOM-BASED CASSAVA  (Manihot esculenta) AGRIBUSINESS DEVELOPMENT THROUGH THE APLLICATION OF AGRO-TOURISM IN THE CIREUNDEU VILLAGE ABSTRACTKampung Adat Cireundeu is one of areas an industrial Cimahi City who maintain the agricultural sector. Primary area (comparative advantage) owned increase potential Kampung Adat Cireundeu agribusiness develop of cassava with the application of agroindustry and agrotourism based on local cultural. The number of visitors still a little and fluctuates will determine the number of requests products agroindustry because most consumers is visitors of Kampung Adat Cireundeu. The purpose of research is to know the linkages between agroindustry and agrowisata in Kampung Adat Cireundeu and know strategy proper to the development of agribusiness in Kampung Adat Cireundeu based on local cultural. Methods used is the case study by doing descriptive qualitative analysis in 37 respondents with a analysis of perception visitors, WTP, IFE, EFE, and SWOT. The result of the research indicated that the existence of the links between agroindustry and agrotourism in Kampung Adat Cireundeu with the position of strategy at the quadrant 3 that Kampung Adat Cireundeu need diversified strategy. The right strategy to the development agribusiness of cassava in Kampung Adat Cireundeu based on local wisdom, such as 1 ) Introducing products through the medium of in the form of a leaflet given to consumers that never came , 2 ) Created a restaurant Kampung Adat Cireundeu’s nuance, and 3 ) Make many marketing line so the consumer relations the larger. Keywords: Agroindustry, Agrotourism, Analysis Of Percepstion Visitors, WTP, and SWOT.

Abstract

The course of thermodynamics is one of the subjects whose material content consists of real theory and practice and the use of formulas. Therefore, in the application of this course is a need to apply a learning model that is able to help students find and solve problems and be able to explain their findings in achieving the basic competencies of thermodynamics course. The learning model is a Problem Based Instruction learning model based on Blended Learning. This study aims to improve the critical thinking skills of pre-service physics teacher as a result of using Problem Based Instruction based on Blended Learning in the course of thermodynamics. Retrieval of data in this study was conducted on third semester students of physics education study programs that take Thermodynamics course. This research was conducted in September-October 2019. The research method used is quasi-experimental. Quasi-experiments are research carried out on a single group of students. Data analysis in this study used a one-party t-test. The results showed that (1) the application of the Problem Based Instruction learning model based on Blended Learning can improve students’ critical thinking skills, (2) Students’ responses to the application of the Problem Based Instruction learning model based on Blended Learning get a very happy category of ongoing learning.
