This study aimed to utilize waste cooking oil as raw material for biodiesel production and to study the influence of time and temperature of the transesterification reaction on the biodiesel production and its characteristics. The study was conducted by base transesterification with NaOH at a molar ratio of waste cooking oil to methanol 1:6. A combination of three levels of temperature (45⁰C, 55⁰C and 65⁰C) and three levels of reaction time (5 minutes, 10 minutes, and 30 minutes) was performed. Each treatment was conducted with 3 replications. The results showed that the yield of biodiesel was affected by temperature and reaction time. The optimum treatment combination was transesterification at temperature of 65⁰C and 30 minutes of reaction time, which produced 72,87 % methyl ester with a density of 0,85 g/ml, viscosity of 1,65 cSt and acid number of 0,07 %. Although the density and acid number of biodiesel produced met the biodiesel quality standards of Indonesia (SNI), it was not recommended to be used as fuel engine. Keywords: Biodiesel, waste cooking oil, transesterification, temperature and reaction time.

Shallot cultivation in Lampung faces challenges because the land is dominated by ultisol soils, which have low nutrients. Therefore, soil improvement materials such as biochar and fertilizers are needed. This study aims to determine the effect of coconut shell biochar addition on the effectiveness of NPK fertilizer in the production of shallots. The study was arranged in a Factorial Completely Randomized Design consisting of 2 factors, namely the dose of biochar (0, 40, 80, and 120 g/pot) and the dose of NPK fertilizer (0, 0,8, 1,6, and 2,4 g/pot). Each treatment combination was repeated 3 times. Parameters included soil characteristics (pH, soil volume shrinkage) and plant parameters (plant height, number of leaves, canopy area, buld number and diameter, evapotranspiration, fresh root weight, bulb air dry weight, and water productivity. The results showed that coconut shell biochar had a significant effect (α = 0.05) in increasing soil pH and decreasing soil shrinkage. The dose of biochar 80 g/pot (B2) with a dose of NPK 1.6 g/pot (N3) was the best treatment. In this treatment combination, shallots produced an average weight of 120.54 g/pot of fresh stover, 14 bulbs with diameter of 2.05 cm and air dry bulb weight of 70.17 g/pot, and the water productivity of 18.22 kg/m3.

Oil palm (Elaeis guineensis) empty fruit bunches (EFB) have not been utilized optimally. Currently, it is considered as a resource with low economic value. This biomass can be converted into bioenergy through a torrefaction process. Torrefaction is a mild pyrolysis at temperatures ranging between 200 and 300 °C, and it is generally performed under an inert atmosphere. The objective of this study was to evaluate the effects of torrefaction using Counter-Flow Multi Baffle (COMB) on the properties of oil palm EFB pellets. Torrefaction was conducted at 280 °C temperature with a residence time of 4 minutes. The results showed a decrease in the equilibrium moisture content and an increase in hydrophobicity after torrefaction using the COMB reactor. The change in the hygroscopic property could make the oil palm EFB pellet more stable against chemical oxidation and microbial degradation, hence self-heating and auto-ignition during storage could be prevented. The heating value of biomass increased after torrefaction. Torrefaction with the COMB reactor resulted in a heating value of 17.90 MJ/kg, which is comparable with the results of oxidative torrefaction (with longer residence time) of 18.28 MJ/kg. The results suggested that torrefaction using the COMB reactor could provide a great improvement in the quality of the bioenergetic properties of oil palm EFB pellets. However, the high ash content of the EFB pellets implied that the EFB pellets suitable for a small-scale application, but not yet for cofiring in power plants or as a feedstock for gasification.Keywords: Counter-Flow Multi Baffle; oil palm empty fruit bunches; renewable; torrefactionA B S T R A KTandan kosong kelapa sawit (Elaeis guineensis) belum dimanfaatkan secara optimal. Saat ini bahan tersebut masih dianggap sebagai sumber daya bernilai ekonomi rendah. Tandan kosong kelapa sawit (TKKS) dapat dikonversi menjadi bioenergi melalui proses torefaksi. Torefaksi merupakan proses pirolisis ringan pada suhu berkisar antara 200 dan 300 °C dan umumnya dilakukan di bawah kondisi inert. Penelitian ini bertujuan untuk mengetahui pengaruh torefaksi dengan reaktor Counter-Flow Multi Baffle (COMB) terhadap sifat-sifat pelet TKKS. Torefaksi dilakukan pada suhu 280 °C dengan waktu tinggal 4 menit. Hasil penelitian menunjukkan bahwa torefaksi menyebabkan penurunan kadar air kesetimbangan dan menjadi hidrofobik setelah torefaksi dengan reaktor COMB. Perbaikan sifat higroskopis dapat membuat pelet TKKS lebih stabil terhadap oksidasi kimia dan degradasi mikroba, sehingga pemanasan sendiri dan pembakaran spontan selama penyimpanan dapat dicegah. Nilai kalor biomassa meningkat setelah torefaksi. Torefaksi dengan reaktor COMB menghasilkan nilai kalor 17,90 MJ/kg, yang sebanding dengan hasil torefaksi oksidatif dengan waktu tinggal lebih lama, sebesar 18,28 MJ/kg. Hasil penelitian menunjukkan bahwa torefaksi dengan reaktor COMB dapat meningkatkan kualitas energi pelet TKKS. Tetapi pelet TKKS masih memiliki kadar abu yang tinggi sehingga biomassa hasil torefaksi belum sesuai untuk cofiring di pembangkit listrik atau sebagai bahan baku untuk gasifikasi.Kata kunci: Counter-Flow Multi Baffle; tandan kosong kelapa sawit; terbarukan; torefaksi

Harvesting of cassava is still mostly done manually by pulling cassava stems that are ready to be harvested. This study aimed to determine the amount of force required to pull cassava stems. The research was conducted on farmer's land in Bandar Agung Village, Bandar Sakti District, Central Lampung Regency. A sample of 50 cassava trees was selected to represent the center and four edges of 1-ha area sizing of 50-m x 200-m. Measurement of the pulling force of cassava was carried out using a winch supported by a triangular frame of iron pipe and equipped with a 100-kg chicken scale and rope. Parameters included force to uproot cassava stem, soil moisture content, soil hardness, stem circumference, plant height, and cassava tuber weight. The results showed that the uprooting force of cassava stem ranged from 20 kg (196 N) to 70 kg (686 N) with an average of 44.9 kg (440.2 N). The results also showed that the pulling force of cassava decreased with increasing soil moisture content with a range between 196 kN at soil moisture 15,9% and 686 kN at soil moisture 10%. Factors of plant height, stem circumference, and tuber weight also had a positive effect on the pulling force of cassava.

Chronic kidney disease (CKD) is a long-term disease where the kidneys have decreased function. In women who experience prolonged CKD, other problems will arise, namely Menstrual abnormalities. CKD patients who have just undergone hemodialysis therapy are prone to stress, if not treated immediately it will disrupt the menstrual cycle. This research design uses correlation analytic with cross sectional approach. The population in this study were 49 women who suffered from CKD in the hemodialysis unit of RSUD Prof. Dr. Soekandar. Sampling using non-probability sampling technique Consecutive sampling type within a period of 3 weeks. The sample in this study amounted to 43 people. The instruments used in this research are DASS questionnaire and Menstrual abnormalities checklist sheet. Data analysis using logistic regression test. The results showed that 20 respondents (46.51%) had CKD >4 years. For stress levels, it was found that 17 respondents (39.53%) were at mild stress levels. And 39 respondents (90.70%) experienced Menstrual abnormalities. The results of the logistic regression test showed that the p-value = 0.048. It can be concluded that there is a long-standing relationship between chronic kidney disease and stress with menstrual abnormalities in the hemodialysis unit of RSUD Prof. Dr. Soekandar. Women who suffer from CKD in their bodies will experience hyperprolactinemia which will disrupt the menstrual cycle. A person who has just been diagnosed with CKD is prone to stress, which stress will stimulate the release of Corticotropic Releasing Hormone (CRH). Hyperprolactinemia and CRH can affect the performance of Gonadotropin-releasing hormone (GnRH) which lead to menstrual abnormalities.
