This research is the development of e-modules of mangrove species diversity based on the local potential of Pulau Dua Nature Reserve Serang Banten which is a learning media to assist students in introducing the biodiversity of mangrove local potential around and used as teaching materials that are used independently. The purpose of developing this e-module is to produce teaching materials that are valid, practical and effective for use in learning. This local potential-based mangrove species diversity e-module development model uses the Lee & Owens (2004) development model. To see the validity of e-modules, validation of material experts, media experts and teaching materials and field practitioners was carried out. Practicality test with one to one trial of 3 students, small group trial of 12 students and field trial of 36 students. The effectiveness of e-modules was measured objectively using the Simple Paired T test and subjectively using the N-Gain Score on students' digital literacy. The results showed that the e-module of mangrove species diversity developed was valid, practical and effective. There are differences in students' digital literacy before and after being taught with e-modules of mangrove species diversity.

An ineffective learning process can cause students’ critical thinking skills to be low. This study aims to develop an e-module for the diversity of living things based on problem-based-learning (PBL) in improving students’ critical thinking skills. Research and development model from Lee & Owen (assessment/analysis, development design, implementation, and evaluation). This research was conducted at MAN Kota Batu. The research population, namely all of tenth grade students in the school year of 2023, the sample used was 36 students with sampling techniques using non-probability by purposive sampling. The research design was one-group-pre test-post test to measure the critical thinking skills after using the e-module. Based on the results showed that the e-module developed was stated very valid (97, 25%), very practical based on students’ responses (91, 6%) and teachers’ responses (89%), and based on the N-gain score to see the effectiveness obtained a value of .6 which means that the students’ critical thinking skills developed in the medium category after the application of e-module based on Problem-based-learning.

Bactrocera is a pest that is detrimental to citrus farming. Bactrocera attacks cause developmental disorders in citrus fruit, including changes in fruit color (black spots appear from Bactrocera infection) and premature rot. Bactrocera also has a symbiotic relationship with Liberibacter asiaticus which causes Citrus Vein Phloem Degeneration (CVPD) disease which attacks phloem tissue in citrus plants. Bactrocera pest control was carried out by combining plants that have the potential to be used as biocides, namely kitolod, papaya, and lemongrass plants. This combination was used to switch the habits of fruit farmers who previously used synthetic pesticides to control pests. Natural biocides are expected to have the same effectiveness as synthetic pesticides, but leave no residue on cultivated plants. A combination biocide from the three plants was made using the maceration method to obtain an infusion from each plant. Before being tested on Citrus plantations, an assay was carried out using an olfactometer to determine the effectiveness of the biocides. The research revealed that the combination of these three plants has the potential to be used as a natural biocide without leaving residueand causing damage or other developmental disorders to citrus plants.

Penelitian ini bertujuan untuk mengembangkan model Economic Production Quantity (EPQ) yang dimodifikasi dengan mempertimbangkan produk cacat dan proses perbaikan ulang, guna mengoptimalkan manajemen produksi dan persediaan. Model EPQ tradisional, yang biasanya hanya memperhitungkan biaya setup dan biaya penyimpanan, sering kali tidak cukup realistis karena tidak memasukkan biaya tambahan yang terkait dengan produk cacat dan perbaikannya. Oleh karena itu, penelitian ini mengusulkan model EPQ yang lebih detail, yang mencakup biaya perbaikan per unit, serta tingkat produksi dan perbaikan produk cacat. Melalui pengumpulan data empiris dan penggunaan teknik analisis sensitivitas, penelitian ini menganalisis dampak variasi dalam parameter kunci seperti permintaan tahunan, tingkat produksi, dan biaya perbaikan terhadap biaya total. Hasil dari contoh numerikal menunjukkan bahwa model yang dimodifikasi ini lebih akurat dalam mencerminkan kondisi produksi sebenarnya dan dapat secara signifikan mengurangi biaya total dibandingkan dengan model EPQ tradisional. Analisis sensitivitas lebih lanjut mengungkapkan bahwa perubahan dalam variabel-variabel ini dapat memiliki dampak besar pada hasil, menunjukkan pentingnya pemantauan dan penyesuaian berkelanjutan. Hasil yang diperoleh dari percobaan contoh numerikal diatas menunjukkan bahwa jumlah produksi optimal dalam satu siklus sebanyak 5385 unit dengan TIC sebesar Rp. 56.148.621.Yang membutuhkan waktu 6 hari untuk menyelesaikan produksi, repair hingga menghabiskan produk tersebut

This research focuses on the role of promotion and product packaging in increasing the decision to purchase products through Kalome’s Instagram account with the mediation of brand awareness. The objective of this quantitative explanatory research is to explain and analyze the direct effects of promotion and product packaging on purchase decision and their indirect effects through brand awareness. The research population is people who purchase The Scented Candle through Kalome’s Instagram account. The data was harvested from online questionnaires distributed to fifty respondents who have the same strata in the population and was analyzed using Structural Equation Modeling – Partial Least Squares (SEM-PLS) in SmartPLS. This study finds that promotion significantly influences the purchase decision, promotion significantly affects the brand awareness, and that product packaging negatively influences the purchase decision and negatively affects the brand awareness. Furthermore, brand awareness has a significant impact on the purchase decision, mediates the influence of promotion on the purchase decision, and does not mediate the effect of product packaging on the purchase decision.
