Abstract

This research aims to identify the type and amount of soil macrofauna, calculate the population density (K) and the relative density (KR) of soil macrofauna with different water level on peat lands under oil palm stands. This research was carried out by observation, sampling for soil macrofauna data was determined by purposive random sampling method which selected the location in accordance with the purpose of research. The samples of the soil were taken in the circle, live path and die path of oil palm with the total area ​​1 m x 1 m in the soil depth until 15 cm which were repeated 3 times to obtain 18 samples. The data of research were calculated and presented on table, then these data were analyzed by descriptive statistic. These results indicated that the type and amount of soil macrofauna on the circle, live path and die path of oil palm in water level of       43 cm were higher than at 60 cm below in the water soil. The population density (K) and the relative density (KR) of soil macrofauna on the circle, live path and die path oil plam at the water level 43 cm below the soil surface had various types and higher amount than at the level 60 cm.

The process of resolving criminal cases is not only oriented towards the perpetrators but also accommodates the interests of the victims and the community. An attempt was made to bring things back to the way they were before the case. Apart from being rooted in the law that lives in the community, this pattern of case resolution tends to be more effective and efficient so that it does not leave or cause new problems. Secondly, in Indonesia the settlement of criminal cases with customary law commonly known as peace has been carried out since the existence of customary law itself, namely since the existence of the community. This is done not only because it looks at the interests of various parties but is also considered as an effort to cleanse the soul of the person, the community, and the environment from the evils caused by disputes in the community. So, peace is part of the religion or beliefs held by Indonesian indigenous people.

Abstract

Ayakan getar (vibrating screen) banyak digunakan dalam proses pemilahan bahan sesuai ukuran yang dikehendaki. Peralatan ini diaplikasikan di dunia industri dalam skala besar maupun dalam skala kecil di laboratorium. Sektor pertambangan, powder metallurgy, proses kimiawi maupun bidang konstruksi banyak menggunakan peralatan ini. Penelitian ini bertujuan untuk mendapatkan pengaruh sudut kemiringan terhadap unjuk kerja ayakan getar. Unjuk kerja ayakan getar didefinisikan sebagai laju aliran hasil ayakan. Penelitian dilakukan dengan eksperimen. Peralatan ayakan getar berukuran panjang 150 cm dan lebar 30 cm. Ayakan terdiri dari 3 bagian yaitu ayakan halus, sedang dan kasar. Bahan yang digunakan adalah pasir sesuai ukuran ayakan dengan berat masing-masing 1 kg. Sudut kemiringan divariasikan sebesar 5o, 10o, 15o, 20o dan 25o. Sumber gerak digunakan motor listrik dengan variasi kecepatan putar 1000, 1200 dan 1450 rpm. Laju aliran massa bahan divariasikan dengan katup geser pada hopper sebesar 5, 10 dan 15 gram/detik. Pengukuran putaran motor dilakukan dengan tachometer. Pengukuran berat bahan dilakukan dengan timbangan digital. Lama waktu pemrosesan diukur menggunakan stopwatch. Pengambilan data dilakukan sebanyak 3 kali ulangan untuk masing-masing percobaan. Data hasil penelitian dihitung nilai rata-ratanya. Laju hasil ayakan merupakan hasil bagi berat bahan dan lama pemrosesan. Hasil penelitian menunjukkan bahwa sudut kemiringan ayakan getar berpengaruh terhadap hasil ayakan. Semakin besar sudut kemiringan maka waktu proses menjadi semakin kecil. Semakin besar sudut kemiringan maka laju pengayakan bahan menjadi semakin besar.

Abstract

Phyllanthus niruri L., a medicinal plant from the Phyllanthaceae family, is widely recognized in traditional medicine for its flavonoid content in the leaves, which functions as a natural antioxidant protecting cells from damage caused by free radicals. This study aims to investigate the effect of the Maceration Vortex Technique (MVT) on the total flavonoid content of Phyllanthus niruri leaves. The method involved a 2-hour maceration process followed by 5 minutes of vortexing using 70% ethanol as the solvent. Total flavonoid content was analyzed using UV-Vis spectrophotometry at a maximum wavelength of 431 nm. The results demonstrated that the MVT method yielded a high flavonoid content, indicating the technique's effectiveness in extracting flavonoid compounds from Phyllanthus niruri leaves. The study concludes that MVT is a promising alternative extraction method that is efficient, simple, and applicable for obtaining bioactive compounds from natural sources. These findings have positive implications for the development of antioxidant-rich herbal products derived from natural ingredients.

Abstract

This research is motivated by the presence of students from broken home families who lack confidence in their career choices and are not yet able to develop their careers. This study aims to understand the career choices of students from broken home families from the following aspects: 1) self-confidence in career choices, 2) responsibility in career choices, 3) guidance and self-development, 4) perseverance, creativity, and initiative, 5) desire to independently pursue their career choices. This type of research uses qualitative descriptive methods with 2 key informants, SH and KAR. Additional informants include 4 people, EDF, ALN, W, and N. Data collection techniques involve interviews, and the analysis technique includes data reduction, data presentation, and drawing conclusions. The results of this study show differences between the two informants, SH and KAR, in choosing a career: 1) SH students are confident in choosing a career because they already know their interests and talents. Informant KAR shows relatively low confidence because they do not know their interests and talents. 2) SH students have a responsible attitude and effort in the learning process, both in theory and practice, while KAR students tend to be lazy during practice and do not focus on their chosen field. 3) SH students can identify their potential in the automotive field and are able to develop their potential, while KAR students are still confused about their potential despite attending a career-focused school. 4) SH students have not yet applied the three aspects of diligence, creativity, and initiative in their career choice process, but they have applied these three aspects in their learning process. KAR students do not apply these three aspects in their learning process. 5) SH students have internal motivation to choose a career, while KAR students lack internal motivation. The results of this study indicate that students from broken home families tend to face obstacles in making career choices. Therefore, it is recommended that the school, particularly the guidance counselors, provide more intensive and directed career counseling services.
