Abstract

This paper describes result of research about measurement of degree ofwilting in black tea processing. Degree of wilting was observed by measuring of tealeaves mass loss because the loss of water content. Mass sensor used is single pointload cell type CZL 601 that can measure up to 20 kg. Results of calibration of load cellgives the characteristic equation V = 0.0001 m + 0.2014 volts. Output of sensor isconnected with instrumentation amplifier which with applying three IC OP-07 whichsubsequently became data process for mirokontroller ATMega8. Data measurementresult interfaced on the LCD. Instrumentation system was implemented in miniprocess factory at Indonesian Research for Tea and Cinchona Gambung, Bandung.Results of measurement of mass loss in a trough of 48.39%, whereas in the samplebasket was 49.33%. Measuring the degree of wilting during the withering of theproduction process is 37.00%.

Abstract

Kajian tentang karakteristik kaolin lokal asal Tatakan, Tapin, KalimantanSelatan setelah proses kalsinasi pada temperatur 800°C selama 3 jam telah dilakukanuntuk mengetahui perubahan struktur kaolin. Sampel kaolin sebelum dan setelahproses kalsinasi dianalisis menggunakan spektroskopi infra merah (FTIR), difraksisinar X (XRD) dan scanning electron microscopy (SEM). Hasil analisis menggunakanFTIR menunjukkan terjadinya kerusakan struktur dari kaolin akibat proses kalsinasiyang ditandai dengan hilangnya puncak serapan khas dari kaolin. Berdasarkan dataXRD dan analisis morfologi menggunakan SEM, proses kalsinasi menyebabkanperubahan struktur kaolin dari pseudoheksagonal berlapis menjadi fasa amorf.

Abstract

Self Potential research has been done in the area of geothermal prospectsof Slamet Volcano, with locations is at around the hot water sources of PancuranTujuh Baturaden, District of Banyumas, Central Java. Tools used in this study wereporous pot electrodes and digital milivoltmeter that have very high input impedance.Dimension of research area are 24 x 24 square meters, with the number ofmeasurement points are 112 point. The electrode configuration used is the fixedmodel that is by keeping one electrode fixed at the reference point, while the otherelectrode moved at any interval in accordance with the direction of trajectory in theresearch area. According to the results obtained is known that the highest potentialdata obtained is -2.20 mV, the lowest data is -40.83 mV, and then the average data is-16.40 mV. According to the contour map of iso-potential obtained is known that thestudy area is a conductive zone, which probably contains of sulfide minerals in thesubsurface hot fluid. This is indicated by the low value of the measured self potential(its value are negative). According to qualitative and quantitative interpretation, knownthat the flow of subsurface hot fluid in following the change of research areatopography and self potential anomalies. The subsurface hot fluid in research area ispredicted flow from southern to northern.

Abstract

Telah dilakukan pengukuran lapisan akuifer di Rampa Manunggul,Kabupaten Kotabaru berdasarkan kelistrikan bumi dengan konfigurasi Schlumberger.Pengukuran ini bertujuan untuk mengetahui kemungkinan adanya lapisantanah/batuan yang berfungsi sebagai perangkap air (akuifer) yang dapatdipergunakan sebagai dasar dalam perencanaan pengembangan air bawah tanahdengan cara pengeboran. Nilai tahanan jenis di lokasi pengukuran antara 0,47–0,48Ωm pada bagian atas ditafsirkan sebagai lumpur penutup yang bersifat basah,tahanan jenis 10-30 Ωm ditafsirkan sebagai lempung pasiran, dan tahanan jenis 30 –300 Ωm ditafsirkan sebagai lapisan pasir. Untuk lokasi pengukuran di RampaManunggul, Kotabaru lapisan air tanah yang bersifat tawar pada kedalaman lebih dari>60 meter.

Abstract

The availability of productive land becomes one of the main problems in thedevelopment of food security and independence of Indonesian farmers. After theregional autonomy era begins, the food business is the responsibility of localgovernment, both at provincial and district / city, the implementation and operationalexcellence tailored to the potential for their respective regions. Act No. 7 of 1996 onFood, in particular article 45, 46, 47, and 48 explain that achieve food security is theresponsibility of the government and the community. In order to support making theright decisions to maintain local food security, support is needed more accurate data,especially in raw paddy fields as the main source of producing rice. Extensive datacollection of raw paddy fields along with other supporting data, basically to increasethe availability of extensive data and information materials on various levels ofadministrative fields that have a high accuracy. Satellite imagery interpretation thatcan produce high accuracy is high-resolution satellite imagery such as Ikonos orimage Quickbird image. Based on the results of this mapping is concluded that thetotal land area of raw rice is obtained from measurements in four districts (Kec.Barabai, Kec. Labuan Amas Selatan, Kec. Labuan Amas Utara and Kec. Haruyan) inMiddle River Upper District is 25,277.35 ha consisting of 9,311.17 ha of rainfedlowland, 1,876.00 and 14,090.18 ha irrigated lowland.

Abstract

The measurement had been conducted about an identification ofgeothermal fluid in heated pool tourist territory Murung B village, Hantakan subdistrict,Hulu Sungai Tengah regency. This research aims to find out litolhogy soil/rock in thearea around the hot water pool, knowing the value detainees soil type/rock containinggeothermal fluid and determine the distribution methods of arrest. Electrodeconfiguration used method Schlumberger (1D) and pole-pole (3D). Referring to theresults of the processing of Progress program can be made two-dimensional crosssectionto find out manually litolhogy coating model soil / rock which then correlatedwith ploting 3D models of Res3Dinv program. Geoelectric research results indicatethat the geothermal fluid in the surrounding in heated pool tourist territory, Hantakansubdistrict, Hulu Sungai Tengah regency has a range of resistance values between108 - 663.60 Ωm, in the depths of 14.67 - 90.2 m from the point G-3 - G-1. Geothermalfluid distribution direction at the research area is spread laterally from the point G-3 -G-1 where a layer of sand mixed with clay and granite rock fragments as an area ofconductive layers and clay as cover.

Abstract

Sistem pengolahan air bersih terdiri dari beberapa unit yakni Raw WaterIntake, bak pengumpul, Pulsator, Filter, Storage Well, Reservoir dan Clear Well. Padadasarnya proses pengolahan air bersih pada tiap unit sudah dilakukan secaraotomatis namun untuk pengoperasian pompa masih dilakukan secara manual,khususnya pada pengisian bak pengumpul dari raw water intake. Penelitian inimemodelkan penggunaan kontrol otomatis untuk mengatur proses pengisian bakpengumpul dari raw water intake. Kontrol otomatis yang digunakan yaitu pengontrolPID. Pengontrol PID berguna untuk mendapatkan kestabilan sistem pengisian bakpengumpul PDAM dan Simulasi pengontrolan PID ini dilakukan dengan menggunakansofware Labview 7.1. Simulasi ini merupakan top level VI yang terdiri dari 3 buahsubVI yakni subVI bak pengumpul berfungsi untuk menghasilkan level air aktual danmenghitung debit air yang keluar dari bak pengumpul, subVI pengontrol PID berfungsiuntuk menghasilkan sinyal kontrol dan subVI kontrol valve berfungsi untukmenghasilkan persentase bukaan valve. Dari hasil penelitian didapatkan bahwaproses pengisian bak pengumpul PDAM dari raw water intake dapat diperoleh cukupdengan memasang pengontrol integral (I) saja, karena dengan nilai konstanta I (Ki) =3,985 sudah dapat menghasilkan sistem pengisian bak pengumpul PDAM yang baikpada waktu 2656 detik.
