The research objective was to find out borax and formalin content in snacks at Lubuklinggau palm trees citypark. The research was a qualitative descriptive research with snacks samples as the object of the research. The data collection was conducted through observation and documentation. The data were analyzed qualitatively through borax and formalin test content by using test kit. The color change on yellow paper test turned into red brownies indicated a positive result of borax content and the color change in the liquid into purple indicated formalin content. The result of the test content with borax and formalin test kit on 187 samples showed the negative result on borax content. The test on formalin content indicated that there were 22 samples that use formalin such as 15 sausage samples, 2 noodle samples, 4 meatball samples and 1 tofu sample. Based on the research result, it can be concluded that the tested samples contain zero borax. In contrast, some snacks contain formalin, such as sausages, noodles, meatballs and fried tofu found at some street vendors. Keywords: snacks , borax, formalin

Lake Aur has many aquatic biota as well as become one of the mainstay attractions in Musi Rawas Regency. Community activities and lack of awareness of tourists on the cleanliness and importance of maintaining the lake environment have an impact on water pollution. One of the organisms that can be used as an indicator of river water quality is microalgae. The purpose of this study is to determine the types of microalgae Bacillariophyta divisions that exist in the lake Aur, Musi Rawas.The type of research used is survey research. Bacillariophyta Division consists of two classes, 6 orders, 7 families, 8 genera and 11 species. Observed environmental factors: temperature: 290C, pH: 6.7, Brightness: 115 cm and dissolved oxygen amount of: 38 mg / L. Based on the results of research and discussion, we can conclude that: the type of microalgae division bacillariophyta were found in Lake Aur namely: Cylotella sp, Eunotia sp, Eunotia pectinalis, Fragilaria croronensis, Synedra acus, Nitzschia sp, Nitzschia acicularis, Surirella sp, Surirella elegans, Pinnularia sp and Stauroneis sp.

The purpose of this research is to determine the effect of liquid organic fertilizer of banana stem on the growth and productivity of 3 types of mustard. This type of research is a descriptive quantitative with an experimental method. The study design used a completely randomized design (CRD) with three treatments and eight replications. Data collection by observation using observation sheets. The data obtained were analyzed by analysis of variance (ANOVA) in one path and continued with LSD. Based on the results of the research, there are differences in the effect of giving Liquid Organic Fertilizer to banana stem on the plant height parameters of three types of mustard. The plant height parameters of chinese green cabbage, and collards meat are significantly different from those of green mustard. There are differences in the effect of giving Liquid Organic Fertilizer banana stem to the parameters of the number of leaves of three types of mustard. The parameters of the number of chinese green cabbage and green mustard leaves are significantly different from collards meat. There is a difference in the effect of Liquid Organic Fertilizer on banana stem on the wet weight parameters of three types of mustard. The parameters of wet weight of chinese green cabbage and green mustard are significantly different from collards meat.

The present study aimed at improving the attitude and behavior of the students of SMPN 2 in waste management through the implementation of problem based learning (pbl) aided by 6M based waste management module. This study was a classroom action research (CAR), and the subjects of the study were 129 students. The problem based learning consisted of several stages, covering: the orientate the students to problems, ask the students to study, guide the students to individual and group investigation, develop and present the students' works which are supported by 6M based waste management module utilization that is able to change the students' attitude and behavior towards waste. The data of the students' attitude were collected through Likert scale, while the data of the students' behavior were collected through questionnaire. Other supported data were collected through observation. The data which were obtained from the attitude scale and the behavior checklist were analyzed by using N-gain score. The result of the study showed that the mean score of the students' attitude in cycle I was 79.8 increased into 88.5; while in cycle II increased from 78.0 into 92.0. The cycle I N-gain score increased from 0.4 (moderate) to 0.6 (moderate).The result of the study showed that the mean score of the students' behavior in cycle I was 50.6 increased into 56.2; while in cycle II increased from 59.2 into 81.9. The cycle I N-gain score increased from 0.1 (low) to 0.6 (moderate). Those means showed that the implementation of Problem Based Learning (PBL) strategy aided by 6M based waste management module can improve the students' attitude and behavior in managing wastes.
