Abstract

Daerah penelitian terletak di daerah Sako Merah dan Manau, Provinsi Jambi, termasuk dalam wilayah Ijin Usaha Pertambangan (IUP) PT ANTAM Tbk. Sampel batuan diperoleh dari singkapan dan bawah permukaan (pemboran) yang mewakili elevasi singkapan. Di daerah Sako Merah, mineralisasi urat kuarsa terdapat pada batuan volkanik berjenis vitrik tuf, kristal tuf, lapili tuf, breksi tuf, dasit, dan andesit serta diorit. Zona alterasi dibagi menjadi tiga zona, yaitu propilitisasi, argilik, dan silisifikasi. Analisis inklusi fluida menunjukkan temperatur pembentukan mineralisasi berkisar antara 260oC-290oC dengan salinitas 1,6-2% wt NaCl ekuivalen. Hasil XRD, menunjukkan adanya mineral lempung, illit, kaolinit, nakrit, dan serisit. Struktur urat kuarsa terdiri dari breksi, masif, dan amethyst. Tekstur urat kuarsa terdiri atas colloform, crustiform, comb, banding, drusy, saccharoidal, dan zoned crystal. Hasil mineragrafi terdiri dari pirit, magnetit, dan oksida besi, limonit/gutit. Di daerah Manau, mineralisasi urat kuarsa terdapat pada batuan volkanik berupa lapili tuf dan vitrik tuf. Zona alterasi dibagi menjadi empat zona, yaitu propilitisasi, sub-propilitisasi, argilik, dan silisifikasi. Struktur urat kuarsa terdiri dari breksia dan tekstur terdiri dari drusy, crustiform, zoned crystal dan saccharoidal. Hasil mineragrafi terdiri dari pirit dan oksida besi. Indikasi mineralisasi di daerah Sako Merah dan Manau, memiliki karakteristik yang relatif sama dengan model mineralisasi pada tipe epitermal sulfidasi rendah.Kata kunci : Sako Merah, Manau, IUP, Tekstur kuarsa, Alterasi, Epitermal.

PETUNG DALAM PRIMBON JAWAHartonoFKIP Universitas Sebelas Maretemail: hartono@fkip.uns.ac.idAbstrakPenelitian ini bertujuan: (a) mengklasifikasikan, (b) mendeskripsikan makna, dan(c) menemukan sistem kognisi dan kearifan lokal petung primbon Jawa. Jenis penelitianini adalah deskriptif kualitatif.Sumber data penelitian adalah Kitab Primbon BetaljemurAdammakna (KPBA). Tahapan penelitian meliputi: (a) terjemahan harfiah; (b) analisiskonteks; (c) analisis ciri-ciri khas primbon; (d) analisis makna primbon; dan (e) menemukansistem kognisi dan kearifan lokal. Hasil penelitian sebagai berikut. Pertama, petungprimbon berdasarkan keperluannya diklasifikasikan menjadi 16 petung, sedangkanberdasarkan simbol yang digunakan diklasifikasikan menjadi 57 petung. Kedua, petungprimbon Jawa tidak bisa dipahami hanya berdasarkan makna harfiahnya, tetapi perlumempertimbangkan makna lain yang membentuknya. Ketiga, petung primbon merupakanakumulasi dari kearifan lokal yang dapat menghasilkan ilmu titen. Ilmu titen dapatmembangun sebuah sistem kognisi yang menghasilkan kearifan lokal berisi nasihat bijakuntuk generasi mendatang.Kata kunci: petung, primbon Jawa, sistem kognisi, kearifan lokalPETUNGIN A JAVANESE PRIMBONAbstractThis study aims to: (1) classify, (2) describe meanings, and (3) investigate the cognitionsystem and local wisdom in petung (calculations) in a Javanese primbon (a handbookcontaining predictions). This was a qualitative descriptive study. The data source was KitabPrimbon Betaljemur Adammakna (KPBA). The research stages included: (a) literal translation;(b) analysis of contexts, (c) analysis of typical characteristics of the primbon, (d) semanticanalysis of the primbon, and (e) investigation of the cognition system and local wisdom.The research findings are as follows. First, types of petung in the primbonbased on theneeds are classified into 16 types and those based on the symbols are classified into 57types. Second, petung in a Javanese primbon cannot be conceived based on the literalmeaningonly, but other meanings constituting petung should be considered. Third, petungin a primbon is an accumulation of local wisrom resulting in ilmu titen (insight based onrepeated observations). Ilmu titen can construct a cognition system resulting in localwisdom containing wise advice for the next generation.Keywords: petung, Javanese primbon, cognition system, local wisdom

Abstract

Cost profit volume analysis is a tool used by management to do a shortterm profit planning by using an approach to costs, volume of sales, and profits. The purpose of its research is to determine the application of the analysis of cost volume profit at PT Inko Java Semarang in profit planning with the calculation of contribution margin, contribution margin ratio, break-even point, the analysis of the profit target, margin of safety, degree of operating leverage, shut down point, and sensitivity analysis. Data that used in this final project is secondary data consist of the sales and costs data in 2017. Data collection was obtained by interview and documentation. The writing method thatused are description and exposition method. The results of this research showed that break-even point was at the sales value of Rp 51.560.373.141,52 or 148.868 units with an average contribution margin per unit of Rp 41.217,04and contribution margin ratio amounted to 11,90%. The profit target set at 1% of the sales in 2017. To reach the expeceted profit, the volume of sales must be Rp 55.520.899.913. Margin of safety are Rp 3.960.526.771,48or by 7,13% and the degree of operating leverage amounted to 11,90. Shut down point occurs at the level of sales of Rp 45.823.939.568,56.

Abstract

Abstract  A manual hydraulic press machine with a capacity of 20 tons is a production tool that functions to press or press thick-layered workpieces with the help of a hydraulic pump. The aim of this research is to determine the process of making a manual hydraulic press machine with a capacity of 20 tons. In this research, the research method used is a descriptive qualitative research method, because this research will only explain the process of making a 20 ton capacity manual hydraulic press machine, therefore research activities are only limited to finding out about tools and materials. what is needed in the process of making the machine and also about the process of making the machine. Based on research, the appropriate materials used in the process of making a 20 ton capacity manual hydraulic press machine are materials that have been well tested, such as UNP ST 37 iron material which produces a maximum tensile strength of 481,559 N/nm2 with a loading force of 77, 5000 kN. and in testing assental iron with a diameter of 16mm and a length of 24cm, it produces a bending test of 17.6044 kgf/mm2 with a loading force of 3,575.06 kgf, has a yield load of 56.4063 kN and a tensile load of 350.490 N/nm2. Apart from that, in making a manual hydraulic press machine with a capacity of 20 tons, there are several processes, namely design, measuring, cutting, welding, smoothing, assembling, punching, and painting and tensile testing on ST 37 steel plates.
