Abstract

The objectives of the study are to obtain optimum yield of extraction red rice bran oil, to determine the physico-chemical characteristics, and componen coumpounds. Data was analyzed using Nir Parametric Statistics by Friedmann test. The result showed the optimum extraction results was obtained by the ratio of substrate : solvent of 1: 8 and the oil yield was 12.31 ±0.325%. The physico properties of red rice bran oil were greenish brown colour, with a density ranged from 0.908 ± 0.014 to 0.922 ± 0.014 (g/mL), and the water content ranged from 0.87 ± 0.06 to 0.91 ± 0.02 %. The chemical properties of red rice bran oil were: the acid number ranged from 116.41 ± 1.22 to 118.11 ± 2.45 (mg NaOH/g); the saponification number ranged from 193.74 ±21.88 to 199.62 ± 12.63 (mg KOH/g); and the peroxide number ranged from 24.37 ± 2.44 to 26.07 ± 4.88 (mgek/kg), respectively. Oils was analyzed used GC-MS. The chemical components of rice bran oil are oleic acid (46.24%), palmitic acid (18.25%), linoleic acid (13.29%), 9-octadecane(7.76%).

Abstract

Overripe tempe is a food product that used by peoples in Indonesia as a food seasoning. So far, overripe tempe received less attention than fresh tempe and research of overripe tempe is rarely done. The objective of the study is to identify the fatty acid compounds of the fifth day fermentation overripe tempe oil before and after purification . The overripe tempe oil of fifth day fermentation was extracted with soxhletation method using n – hexane solvent, then it was purified. The various fatty acids of overripe tempe oil were analyzed by GC – MS. The purification process was done by using H3PO4 0,2% and NaOH 0,1N. The result of the study showed that before purification the oil was composed of eight compounds are palmitic acid (13,33%), linoleic acid (77,57%), stearic acid (6,15%), and the five chemical components, Dasycarpidan – 1 - methanol, acetate , oleic acid, 9 - Octadecenamide ,Cholestane - 3, 7, 12, 25 - tetrol, tetraacetate, (3?, 5?, 7?, 12?) and 6, 7 – Epoxypregn – 4 – ene -9, 11, 18- triol - 3, 20 - dione, 11, 18 – diacetate have percentage of areas less than 3%. After purification the oil was composed of palmitic acid (12,38% ), linoleic acid (80,35 %), stearic acid (5,84%), and 17 – Octadecynoic acid (1,42 %) .

Abstract

Extract of Candlebush (Senna alata L. Roxb) flowers and leaves show toxicity effect on Artemia salina Leach. The crude extract was obtained by maceration method using methanol 80% and followed by partition into hexane, chloroform and ethylacetate. Data was analized using Randomized Completely Block Design (RCBD) Sub Sampling, that consisted of six treatments, five replications and three sub samples. To compare the differences between the mortality rater of A. salina, the Honestly Significant Differences (HSD) at 5% level of significance was used. Furthermore, to determine the LC50, the probit analysis was used. The results of this study show that the most effective toxin from all fractions of S. alata was the hexane fraction of the leaves extract. The LC50 of S. alata crude extract of leaves was 187,72 ppm (hexane fraction) and 290,34 ppm (EtOAc fraction). The crude extract of S. alata flowers toward A. salina were 210,77 ppm (hexane fraction) and 354,49 ppm (EtOAc fraction). In general, this study showed that all fractions which were tested had the toxic activity on A. salina.

Abstract

This study aims to determine the effect of anxiety facing work termination on employee motivation at PT X Salatiga. The sample in this study amounted to 73 respondents who are still active employees working at PT X. The sampling technique is done by simple random sampling. Data collection uses a psychological scale that is the scale of work motivation based on Abraham Maslow's motivation theory and anxiety facing retirement scale based on the theory put forward by Oluseyi & Olufemi. The data used are primary data analyzed using a simple linear regression test. The results showed that anxiety facing work termination affects work motivation by 26.8% while the remaining 73.2% is influenced by other variables not examined. The researcher can then study based on age, position and also examine other variables that are factors of work motivation, for example marital status between married employees compared to employees who have not married, the length of service of employees in a company.

Abstract

Menikmati masa purna tugas dengan bahagia merupakan harapan semua orang, namun tidak semua orang mampu mencapai kepuasan hidup dan kebahagiaan sebagai bagian dari kesejahteraan psikologis subjektif (subjective well-being) di hari tua. Salah satu penyebab sulitnya seseorang menjalani purna tugas adalah kekhawatiran berlebihan akan hidup dan kesehatan fisiknya. Penelitian ini bertujuan untuk menentukan pengaruh perilaku sehat dan dukungan sosial secara simultan terhadap subjective well-being purna tugas PT PLN Persero di kota Ambon berdasarkan status kerja. Pendekatan kuantitatif digunakan dalam penelitian ini dengan 168 responden yang terdiri dari 90 purna tugas dan 78 karyawan jelang purna tugas menggunakan purposif sampling. Skala Health Behavior Checklist (HBC), Skala Multidimensional Scale of Perceived Social Support, dan skala Satisfaction With Life (SWLS) dan Positive Affect And Negative Affect Scale (PANAS) digunakan dalam pengumpulan data. Hasil penelitian menunjukan bahwa hanya perilaku sehat yang berpengaruh terhadap subjective well-being pada purna tugas maupun juga jelang purna tugas. Pada purna tugas hasil (R=0,632) dengan nilai F=114,020 dan nilai signifikansi= 0,000(p<0,05) dan R2=40,4%, sedangkan jelang purna tugas (R=0,775) dengan nilai F= 205,453 dengan nilai signifikasi 0,000(p<0,05) dan R2=60,44%. Uji Beta t-test subjective well-being antara purna tugas dan jelang purna tugas menunjukan nilai t=1,037 dengan signifikasi sebesar 0,301>0,05 sehingga dapat disimpulkan tidak ada perbedaan subjective well-being pada purna tugas maupun jelang purna tugas.Kata Kunci: perilaku sehat; dukungan sosial; subjective well-being

Tradisi pengasingan ini merupakan bentuk kearifan lokal yang masih dipertahankan pada era milenium. Penelitian bertujuan menganalisis kebutuhan dan masalah mendasar yang dialami perempuan di rumah pengasingan berdasar kajian psikoanalitis Jung. Metode kualitatif dan teknik studi kasus digunakan untuk menganalisis kebutuhan dan masalah serta nilai-nilai kesejahteraan hidupperempuan dalam pengasingan di Buru Selatan dan Buru Utara. Unit amatan adalah 8 perempuan yang sedang dan pernah dimasukkan dalam rumah pengasingan. Unit analisis mencakup pengalaman psikologis, reaksi emosional, interaksi sistem psiko-spiritual-budaya dan biologis. Hasilnya adalah tradisi turun temurun sebagai warisan budaya sudah membentuk sistem kepribadian melalui ketidaksadaran kolektif. Sekalipun dilakukan melalui keterpaksaan dan ketidakberdayaan, namun arketipe sebagai bagian struktur warisan, dirasakan oleh subjek kajian mampu memberi petunjuk dalam mengatasi situasi yang mengancam, dan membuat individu semakin didominasi perasaan emosional. Arketipe yang dominan pengaruhnya adalah kelahiran, kematian, Tuhan, setan dan orang bijak berpengaruh mengatur tingkah laku. Kajian ini memberi petunjuk pentingnya pemimpin masa depan memerhatikanpemerataan pendidikan. Secara empiris pendidikan diharapkan meningkatkan fungsi kesadaran. Self sebagai proses individuasi diharapkan mampu menyeimbangkan kesadaran dan ketidaksadaran, sehingga dalam mencapai realisasi diri, kepribadian yang sejahtera dapat terintegrasi secara harmonis dalam ego melalui fungsi psikis yang religius.

Abstract

Batik is a cultural product of Indonesia and it is produced by home industries under Putting Out System (POS). Although batik home industries are beneficial economically, their impacts on environment tend to be destroyed due to water pollution resulted from the process of POS. Moreover, batik production by POS is considered to disadvantage female homeworkers. This paper aims to explain the benefit of batik industries in Jarum Village, Klaten toward female homeworkers, even if water pollution occurs in the village. Batik industries give benefit because they provide employment for female homeworkers in Jarum Village. Unfortunately, the benefit from batik production not yet received by some female homeworkers due to low wages they get, in addition to the pollution which could contaminate the groundwater they use for domestic activities. Finally, batik benefits are not merely regarding economics context as batik provides a space for self-actualization, mainly to the elder workers.
