Abstract

Sistem komunikasi nirkabel dengan menggunakan modul nRF24L01+ yang memanfaatkan gelombang Radio Frequency 2.4 GHz  telah diimplementasikan pada Ading Pintar (Automatic Feeding Penebar Pakan Ikan Pintar). Sistem ini digunakan untuk menampilkan informasi terbaru yang dikerjakan oleh ading pintar. Informasi yang dikirimkan oleh ading pintar kemudian diterima oleh modul yang disebut sistem slave. Informasi tersebut terdiri dari status pemberian pakan serta kondisi suhu dan pH air kolam. Informasi yang diterima oleh sistem slave disimpan di dalam memori, dimana data tersebut dapat menjadi bahan evaluasi kinerja ading pintar oleh pemilik kolam. Implementasi sistem komunikasi nirkabel ini menggunakan beberapa komponen diantaranya, Arduino Mega 2560, modul nRF24L01+, modul LCD keypad shield, modul RTC DS3231, Modul SD Card serta modifikasi program pada ading pintar dan sistem slave.  Pengujian sistem dilakukan selama 4 hari secara terus-menerus dengan menempatkan ading pintar di laboratorium instrumentasi fisika FMIPA ULM sedangkan sistem slave ditempatkan di laboratorium komputasi fisika FMIPA ULM. Berdasarkan hasil pengujian, sistem komunikasi nirkabel pada ading pintar dan sistem slave bekerja dengan baik, dimana informasi suhu dan pH air kolam yang dikirimkan oleh ading pintar sama dengan yang diterima oleh sistem slave. Selain itu status pemberian pakan juga bekerja dengan baik, dimana setelah ading pintar selesai memberi pakan, indikator pemberian pakan yang tertera pada LCD sistem slave yang semula tanda silang berubah menjadi tanda centang. Tanda tersebut akan secara otomatis direset menjadi tanda silang setiap pukul 00:00 WITA.

Abstract

One of the potential of ecotourism in South Kalimantan that has not been much explored is the Liang Bangkai site in Tanah Bumbu. Ecotourism on the Liang Bangkai site highlights conservation in its cultural aspects and natural authenticity, without ignoring the economic aspects that are indicated to be unique and of high value. The artifact findings on this site are far more complete than the Sakulirang site, a site recommended by UNESCO as a world heritage (Sugiyanto, B., 2010). It is not easy for local governments to determine the right strategy in tourism promotion. This is related to many factors, one of which is the carefulness and thoroughness of the local government as decision makers in determining the criteria that are the strengths, weaknesses, opportunities and threats of each tourist location. Accuracy of the local government in digging information on each criterion built both externally and internally, then analyzed so that it can provide accurate information related to tourist sites and be able to formulate appropriate and measurable decision strategies for the promotion of ecotourism. The Fuzzy Analytical Network Process - Extend Analysis Chang method is used in determining the weight of interest between criteria and sub criteria and the weight of interest between promotion strategies. Based on the perception of the importance level of the sub-criteria for promotion strategies, the level of importance was found, namely Strengts - Opportunies (21.70%), Weakness - Opportunities (34.52%), Strengt - Threats (32.54%) and Weakness - Threats (11.24%). From these results, it can be seen that decision makers still emphasize strategies to overcome internal weaknesses to capture opportunities from potential Liang Bangkai sites and utilize the potential strength of the site to overcome external threats to the site.

Abstract

Karakterisasi ukuran partikel menjadi salah satu parameter yang sangat penting dalam uji keberhasilan sintesis mikro- maupun nanomaterial. Walaupun secara teori sudah diketahui bahwa beberapa perlakuan fisika seperti proses penyaringan dan pengeringan dapat berpengaruh terhadap ukuran partikel sampel, tetapi perlakuan ini sering diabaikan sehubungan dengan beberapa teknik karakterisasi, misalnya SEM (scanning electron microscopy) mempersyaratkan sampelnya berbentuk serbuk kering.Penelitian ini bertujuanuntukmendapatkan data imiahtentang pengaruh penyaringan dan pengeringan terhadap ukuran partikel oksida besidengan karakterisasi secara kualitatif menggunakan mikroskop optik. Hasil penelitian menunjukkan bahwa proses penyaringan dan pengeringan dapat mempengaruhi ukuran partikel.

Abstract

The tire repair location is one of the determining factors sought by motorized vehicle users if they are experiencing a tire leak in the middle of a trip. This makes vehicle users panic and think to immediately look for the nearest tire repair location. Banjarbaru City has 5 sub-districts and 12 villages, and is the center of the South Kalimantan Province administration. Given the large number of settlements, especially now that there are many housing complexes in Banjarbaru, this automatically makes the number of new roads opened by the local government. Actually this can be an opportunity for tire repair entrepreneurs to open tire repair locations in several places, because nowadays there are still very few workshops or tire repair locations in the new residential area.Location Based Service System, or better known as LBS, combines the process of a mobile service with the geographical position of its users. The important point is when the target position, where a target might be an LBS user or another entity that is incorporated in a service. This research leads to android based applications and services that provide information of tire repairlocation, to make it easier for motorbike riders to find tire repair locations based on available facilities.

Abstract

The drought is a routine problem that occurs at several region in Indonesia. Due to the drought, water depletion in the Riam kanan watershed sub-district is very large. Several methods are used to find out and analyze the drought that occurs, one of them is the Theory of Run method. The Theory of Run method is a method to calculate the drought index in the form of the longest duration and the largest number of droughts with a certain return period in some area. The results showed that the longest duration of drought occurred in 2009, for 12 months with the largest number of cumulative droughts was 1125 mm. Based on the drought level distribution map, Aranio Subdistrict was the worst region of drought. In 1998-2002, 2003-2007, 2008-2012, and 2013-2017 the area of drought reached 88,918.62 ha, 90,873.6 ha, all of the Aranio Subdistrict regions , and 69,710.34 ha, respectively.
